Wet Today. Chance of Rain/Snow in Western PA Wed. Dry Thursday. Significant Coastal Storm Chances Decline

Posted on
Well it looks like a bit of a shloppy day today, and I know how you kids like ’em shloppy. Looks like rain across the board today before rain changes over to snow overnight in western PA. A chance of rain and snow will persist into Wednesday in western PA before conditions dry out on Thursday. The DC Region will look at partly cloudy skies on Wednesday and Thursday. Highs in western PA will reach into the mid to upper 40s today before dipping into the mid to upper 30s on Wednesday. Low to mid 30s will move in on Thursday. Lows will dip into the mid to upper 30s overnight tonight before 20s settle in on Wednesday night and Thursday night. DC highs will reach into the upper 40s to low 50s today before low to mid 50s settle in tomorrow. Low to mid 40s will settle in on Thursday. Lows in the low to mid 40s tonight will fall off into the low to mid 30s on Wednesday night and Thursday night. Models have shied away from a significant coastal storm this upcoming weekend as they push the system further off the coast and mostly out to sea. Hope you have a fantastic two-for-Tuesday!
