Colder today with many spots in the county struggling to escape the 30's for high temps today. Warmer over the weekend with a pretty big Nor'easter coming up the coast by Sunday evening. The track will be too far inland or close to the coast to allow for anything but rain. Although we could see some snow flurries by Monday night. Temps will fall back to near normal levels for December for much of next week. Records for today: High 65 (2015) / Low 4 (1989) / Rain 2.06" (1897) / Snow 8.7" (1917)

0.37" of rain so far here in East Nantmeal temp at high for the day at 58.4....may pop up another couple degrees before the cold front starts to cross the county during the 7pm hour. Temps should fall pretty quickly back into the 40's

Except for Euro which slightly increased snow totals for the western burbs....

Euro Kuchera also increased snow totals with this run

Euro increased snow totals from 6z run to 12z run here in the western burbs

Rain should be spreading in from the west by late this morning. The models still show a transition to snow from west to east across the area before dawn tomorrow. Both the NAM and the NWS are focused on the higher elevations here in Western Chester, Western Montgomery and Berks Counties for the best chance of an accumulation. Both the NAM and GFS are model in the 3" to 4" amounts for these areas. However, the NWS has only up to 1" possible in these areas. The limiting factor will be temperatures which should remain above freezing in all areas so while I am sure there will be some accumulation where it does snow on unpaved surfaces...unless the rates are heavy enough any issues on the road look slight.

Elevation.....will be the only way this accumulates IMHO....

You have been NAMmed...6" over East Nantmeal and points NE....book it!!

Interesting that it never went below freezing during the event

A bit foggy this AM but it should burn away later and yield a nice mild afternoon. Clouds will be increasing later today with rain arriving by tomorrow morning. Windy and rainy through tomorrow night....all models still show the rain mixing with and changing to some wet snow by Monday morning. Of note the NWS does not have snow in the forecast at this time. However, If it does occur it will be a wet snow with temps never falling below freezing....this does not mean snow cannot accumulate especially in the higher elevations of the county on non-paved surfaces etc. Records for today: 71 (1966) / Low 6 (1989) / Rain 1.80" (2009) / Snow 7.8" (2005)

Rain to snow almost always works out in this area.....right??

Rain to snow Sunday night on a couple models out here in ChescoLand....this rarely works out

A nice couple of days before a nice rainstorm moves in on Sunday. We should see above normal temperatures through the weekend (normal highs are in the low 40's) in fact by Sunday we could see many spots in the 60's. As warm as that is it is still nowhere near a record high. The record high for Sunday is the 70 degree reading from 1946. We turn seasonably colder for the rest of the upcoming week. Records for today: High 70 (1980) (RIP John Lennon) / Low 12 (1959) / Rain 1.94" (1978) / Snow 4.7" (1917)
