Scattered Snow Lingers Today. Dry Conditions Saturday. Models Trend Northward With Storm Sunday: Significant Snow Potential In Western PA Increased.

Definitely keep an eye on the roads this morning as some icy conditions are possible, mainly on untreated surfaces in both the western PA and the DC Region. I know this since I almost slipped on our stoop this morning. Scattered snow showers will linger early in the day today before conditions dry out on Saturday. Sunday will be an interesting system as models trended warmer (and northward) with the system, allowing for significant snowfall chances across all of PA to increase. southern PA could see the best threat of mixing with this system, but all areas should change over to snow at some point. The Pittsburgh region could see 3-6″ with this system, while the higher elevations could see 4-8″ to the east and north of Pittsburgh. Locally higher amounts are possible in higher elevations and wherever heavy band sets up north of rain/snow line. Risks could still occur with NW PA if further warm changes occur. If warmer changes, Pittsburgh could see less snow and NW PA could see more snow. If colder changes, Pittsburgh could see more snow and NW PA could miss out on the substantial snow. I’ll keep an eye on this during the weekend. In the DC Region, we’re looking at a slight risk of light snow showers early this morning before the afternoon dries out and mostly sunny skies move in by Saturday. Sunday looks to be a slop fest, as rain, snow, freezing rain, and sleet are all in the game for potential precipitation. Light or no snow accumulations are expected at this point. This could change if colder changes occur with the models. Hope you all have a fantastic weekend! As always be safe!

Bad News: Slick roads/sidewalks possible this morning. Driving later on Sunday into early Monday could be rough. Use caution.

Freezing Rain/Sleet/Snow/Rain. All in the Mix Today. Chance of Snow Early Friday in Western PA. Partly Cloudy Saturday.

Looking like a mixed bag of tricks today as a wintry mix tracks through the region. Freezing rain could cause some issues this morning in western PA so keep an eye out for slick spots on the roads. 2-4″ of snow is possible just south of the snow belt in NW PA where the snow belt could see 3-6″ or so. Pittsburgh could see light accumulations but there will be a lot of mixing going on.  Looks like tomorrow will keep a chance of snow in western PA early before conditions dry out into the afternoon. Saturday will bring in partly cloudy skies into western PA. Highs in the 30s today will drop off into the mid to upper 10s by tomorrow afternoon before highs bump up into the low to mid 20s on Saturday. Lows overnight tonight will drop into the upper 10s to low 20s before mid to upper single digits move in Friday night. Lows will rise into the 10s and low 20s by Saturday night. The DC Region will see a chance of rain, snow, and sleet later today and into tonight before conditions start to dry out on Friday. Mostly sunny skies will settle in on Sunday. Highs will peak in the Mid 30s to low 40s today before mid to upper 30s push in on Friday. Upper 20s to low 30s will shuffle in on Saturday. Lows in the low to mid 30s tonight will fall off into the mid 10s to low 20s tomorrow night before Saturday night rise into the mid 20s. Still quite a bit of uncertainty for Sunday’s storm as models have trended the system southward. Models are still all over the place with the system and how much moisture/cold air will push into the area. I should have a better idea of where the track will go tomorrow. Hope you all have a fantastic day! The weekend is getting close. Take care folks!

Bad News: Freezing rain/snow risk today could cause slick roads in western PA. Clipper system Sunday into Monday could be interesting for Mid-Atlantic. Uncertainty still there. No significant warm ups over the next couple weeks.

Cold Temperatures and Wind Chills This Morning. Couple Storms Being Watched on Thursday and Sunday.

After a dry day (and some sun) today we go back into a wetter pattern on Thursday as a chance of rain and snow move into western PA. Could also see some brief sleet/freezing rain in NW PA. A chance of light snow could linger into early Friday before conditions dry out again during the afternoon. Snowfall looks to be a sloppy coating to none in Southwest PA Thursday into early Friday while far NW PA could see the best chance of some light accumulations. Highs in the upper 10s to mid 20s today in western PA will rise into the 30s late tomorrow before afternoon highs decline into the upper 10s to low 20s by Friday afternoon. Lows in the 10s tonight and tomorrow night will rise drop into the single digits Friday night. The DC Region will see mostly sunny skies today before a chance of rain and snow moves into the region late and into early Friday. Conditions will dry out Friday afternoon. Highs in the low to mid 30s today will rise into the mid 30s to low 40s on Thursday before temperatures decline throughout the day on Friday giving way to afternoon highs in the mid 30s. Lows in the upper 10s to mid 20s tonight will rise into the low to mid 30s tomorrow night before mid to upper 10s move into the region on Friday night. Stay warm, drink hot chocolate, and have a great hump day. Get over it!

Good News: Winter doesn’t last the entire year. Some relief from bitter cold today with more manageable temperatures on Thursday.

Bad News: Wind chills frigid today. Friday night also gets very cold. Rain and snow on Thursday and then a potentially nastier system on Sunday. I’ll keep you updated on that one in the coming days.

Lingering Light Snow Early Today. Possible Wind Chills Below 0 Wednesday. Another Clipper Brings Rain/Snow on Thursday.

As a coastal storm continues to pound southern New England, some lighter snow is lingering near the DC Region and in parts of western PA currently. This should wind down throughout the day before mostly sunny skies settle into the region on Wednesday. A big story is yet another clipper system tracking into western PA on Thursday. Several models have indicated that NW PA could get a substantial amount of snow this time instead of the bulk of snow across southwestern PA. We’ll see if things change tomorrow but I wouldn’t be surprised to see 2-5″ fall in parts of NW PA on Thursday and overnight into Friday morning. SW PA should see a chance of rain and snow during the day before changing over to snow overnight. The DC Region should also share in this clipper’s love as a mix of rain, snow, and sleet is possible. Highs in western PA will rise into the mid 10s to low 20s today before low to mid 20s move in on Wednesday. Thursday will rise into the 30s across the region on Thursday. Lows in the single digits and low 10s tonight will rise into the mid 10s to low 20s tomorrow night before Thursday night brings 10s to the area. Wind chills below 0 are possible in western PA on Wednesday. The DC Region will see highs in the mid to upper 30s today before values drop off into the low to mid 30s tomorrow. Mid 30s to low 40s will push in on Thursday. Overnight lows in the upper 10s to mid 20s tonight and tomorrow night will rise into the upper 20s to low 30s on Thursday night. Hope you all stay warm and have a great two-for-Tuesday! Take care folks!

Bad News: Wind chills below 0 possible overnight tonight into tomorrow in western PA. Clipper system to bring more snow to western PA Thursday/early Friday.

Light Snow Lingers in Western PA Today. Chilly. DC to see Rain/Snow with Snow Accumulations North of City Through Tonight. NYC/Boston Prepare for Blizzard. 18-24″ Possible.

Well the clipper system brought some snow to much of PA last night, but accumulations were pretty limited with Pittsburgh seeing the bulk of snow with between 3 and 6 inches. Light snow looks to potentially linger on during the day today in western PA as most locations should see an inch or two at most. Mostly sunny skies will push in on Wednesday. The DC Region will see a mix of rain and snow today and tonight, with potential for some accumulation to the north of the city. Could see 1-3″ of snow to the north of DC with possible higher amounts up towards Frederick and northern Maryland. Light snow could continue into early Tuesday before mostly sunny skies move in on Wednesday. Highs in the mid 20s to low 30s today in western PA will drop into the low 20s tomorrow as 20s hold steady into Wednesday. Lows in the mid 10s to low 20s tonight will drop into the upper single digits and 10s tomorrow night before mid 10s to low 20s return Wednesday night. The DC Region will see highs afternoon highs in the mid to upper 30s today and tomorrow before low to mid 30s settle in on Wednesday. Lows in the mid to upper 20s tonight will drop off into the upper 10s to mid 20s Tuesday night and Wednesday night. Worst of coastal storm for NYC and Boston comes later this afternoon/evening and into early Tuesday. Snowfall rates over 1″/hour possible as winds could gust over 60 mph. If you live in NYC, Long Island, Connecticut, Rhode Island, Massachusetts, southern New Hampshire, and southern Maine, prepare to get a hefty amount of heavy, wet snow. As for Philly, somewhere between 5 and 10″ of snow could fall in the region, with the higher amounts possible in eastern Philly and eastward. Overall, a mess of a day, night, and early Tuesday for the Northeast. Be safe and take care folks!

Good News: Drier conditions will help clean up in NYC/Boston on Wednesday.

Bad News:  Blizzard conditions likely from NYC to southern Maine over the next couple days. Don’t drive this afternoon into tomorrow if you are in these locations. Another clipper Thursday into Friday could bring additional snow.

Clipper/Coastal Storm To Affect Mid-Atlantic and Northeast. Blizzard Conditions Possible from NYC to Boston.

I’m still on the boat that Pittsburgh and southwest PA get hit the hardest with the clipper system out of western PA/DC Region. However, potential for a coastal storm to form from this clipper gives potential for Philly, NYC, and Boston to get hammered with a possible foot or more of snow through Tuesday. In all honesty, I think that schools near Philly, NYC, and Boston will be cancelled on Tuesday. I’d imagine Monday schools could also be dismissed early if not cancelled in those areas as well. For western PA, I think that Monday could bring delays and cancellations to the region, especially in southwestern PA. I think schools will be cancelled in the DC Region, mainly north of the city. South of the PA border, this system could start out as rain before changing over to snow, possible adding to an ice threat under the packed snow. So all in all, don’t be a dumbass and drive like an idiot. Be cautious if you have to drive. If you are in the Philly, NYC, or Boston areas, I suggest staying off the roads Monday afternoon through Tuesday. Be safe and as always, if you have any questions feel free to ask. Take care folks!

Forecast Total Snowfall From Today through Tuesday:

  • Erie, PA: Coating-2″
  • Edinboro, PA: 1-3″
  • Oil City, PA: 2-5″
  • Butler, PA: 3-6″
  • Pittsburgh, PA: 4-8″
  • Uniontown, PA: Rain/Mix Becoming Snow. 3-6″
  • State College, PA: 4-8″
  • Frederick, MD: Rain/Mix changes over to snow. 3-6″
  • Germantown, MD: Rain/Mix changes over to snow. 2-5″
  • Washington, D.C.: Rain Changes over to Snow. 1-3″
  • Philly: 8-12″
  • NYC: 10-15″
  • Boston: 15+”
  • New Hampshire/Maine: 10+”

Frost Advisories: Snow Edition: Pittsburgh Region In Line of Fire of Clipper System for Sunday/Monday

For this Nor’easter, not too bad of a forecast for my focus regions. Pittsburgh got about an inch or 2 out of this where the DC Region saw anywhere from a trace near the city to maybe a couple inches up into the northern burbs. The place that I under-forecasted for was southeastern PA, where although Philly itself didn’t get too much the suburbs north and west of the city saw a good 4-8″. Could see some snow showers linger across central and eastern PA today before the region prepares for a clipper system Sunday into Monday. Models have been consistently picking on Pittsburgh with snow. DC Region could also pick up a decent amount. The timing of this disturbance will most likely cause delays with potential for school cancellations as well. As always, be safe driving!

Forecast Snowfall Sunday through Tuesday:

  • Erie, PA: Coating-2″
  • Oil City, PA: 1-3″
  • Butler, PA: 2-5″
  • Pittsburgh, PA: 4-8″ in immediate suburbs. 3-6″ dahntahn.
  • Uniontown, PA: 4-8″
  • State College, PA: 2-5″
  • Frederick, MD: 2-5″
  • Germantown, MD: 2-4″
  • Washington, D.C.: 1-3″

Mixed Precipitation North of DC and into Southern PA Tonight/Early Saturday. Better Chance of Accumulating Snow Sunday Night/Monday.

A Nor’easter will start to push up the coast today, bringing a threat of a wintry mix to the DC Region tonight and into Saturday. Snowfall accumulations should hold mainly to far northern MD and southern/eastern PA. Looking like 1-3″ is possible across far northern MD while areas in eastern PA north and west of Philly could receive 2-4″ or locally more. Some freezing rain could occur as well with this system in these regions, so definitely take it easy on the roads. The DC Region should stay mainly dry today before the threat of rain, sleet, and snow move into the region overnight tonight and into Saturday. Sunday will dry out for most of the day before a clipper system could bring a better chance of accumulating snow to the immediate DC Region. In Western PA, the southern tier could receive some snow tonight before the system pushes northeastward. Pittsburgh could see a coating overall. Conditions should stay mainly dry during the day on Saturday in western PA before a chance of snow moves in Saturday night. Snow looks to pick up later in the day on Sunday and into Monday. Models have trended the heaviest snowfall further southward into southern PA, MD, and DC. I think 2-5″ is possible across southern PA and northern MD Sunday/Monday at this time (still subject to change). Some areas could receive more, depending on where the rain/snow line and heaviest band sets up. If the models have the timing right (they’re probably too slow), the DC commute could be ugly Monday morning. Definitely a lot to keep an eye on heading into the weekend. Drive safe and have a fantastic weekend! Take care folks! 
Risks: Some areas of eastern PA could see higher snowfall totals from Nor’easter. Southerly trend of the snow for Sunday/Monday storm could bring higher snowfall totals to the DC Region/Less NW PA snow as colder air drifts southward. However, some models show less moisture, decreasing the risk. Since most clippers have performed up to snuff or overperformed this year, I’d go with the higher snow totals potential.

Forecast:

Western PA:

Main threat: Snow possible across southern PA tonight. Coating-1″ in SW PA. Better threat of significant snow Sunday night/Monday. 2-5″ possible in southwest PA. 1-3″ possible in NW PA.

  • Today: Clouds increase. Chance of snow mainly in SW PA later. Afternoon Highs: Low to Mid 30s Overnight Lows: 20s
  • Saturday: Chance of light snow. Highs: 30s Overnight Lows: Mid 20s to Low 30s
  • Sunday: Snow likely. Highs: Upper 20s to Mid 30s Overnight Lows: Upper 10s to Mid 20s

DC Region: 

Main threat: Wintry mix could cause slippery roads tonight/Saturday. Slick roads could return Sunday night/Monday as snow pushes in. 2-5″ possible north of DC Sunday night/Monday.

  • Today: Increasing clouds. Chance of snow/sleet/rain. Highs: Low to Mid 40s Overnight Lows: Low to Mid 30s
  • Saturday: Rain, snow, and sleet. A few inches of wet snow could accumulate well north of the city. Highs: Mid to Upper 30s Overnight Lows: Upper 20s to Mid 30s
  • Sunday: Partly sunny. Chance of snow/sleet late.  Highs: Low to Mid 40s Overnight Lows: Low to Mid 30s

Good News: Temperatures stay pretty seasonal through the weekend.

Bad News:  Travel could be rough with a threat of wintry mix tonight/tomorrow from north of DC up the East Coast. Morning commute Monday could be interesting depending on the timing of the system. Colder temperatures also move in next week.

Dry Today and Tomorrow. Rain/Snow/Sleet in the DC Region on Saturday. Potential Significant Snow in Western PA Sunday/Monday.

After a snowy and sloppy day yesterday across the region, conditions start to dry out over the next couple days. Western PA will see mostly cloudy skies today before I bring some sunshine to the region on Friday when I drive up. Saturday will increase clouds across the region before a chance of snow moves in mainly later in the evening. The DC Region will see mostly cloudy skies today before mostly sunny skies settle in on Friday. A chance of snow and sleet is possible overnight Friday into Saturday before changing over to rain and snow during the day Saturday. A few inches of wet snow is possible for the northern burbs and into northern MD, but a cold air source region isn’t in place to keep temperatures cold enough for all snow. Highs in western PA will sit in the mid 20s to low 30s today before 30s settle in on Friday. Saturday will allow for mid to upper 30s across the region. Lows in the mid 10s to low 20s tonight will rise into the 20s tomorrow night before Saturday night brings in mid 20s to low 30s. The DC Region will look at highs in the low to mid 40s today and tomorrow before upper 30s settle in on Saturday. Lows in the mid 20s to low 30s tonight will rise into the low to mid 30s tomorrow night before upper 20s and low 30s push in Saturday night. Looks like accumulating snow should occur on Sunday and into Monday across PA, but models disagree on the track and amount of moisture with this system currently. DC could also receive some accumulating snow late Sunday and into Monday.  I will hopefully have a better outlook tomorrow. I’ll keep yinz updated with the forecast. A couple more work days until the weekend. Take care folks!
