With a cold frontal passage this AM we have already reached our high temperature for the day. We should see our temperatures hold steady this morning then fall this afternoon. We should reach freezing during the 6pm hour across much of Chester and Berks Counties. We then look to stay below freezing tomorrow and through rush hour on Thursday. This sets the stage for a messy mix of snow to sleet to freezing rain before it tapers off from southwest to northeast on Thursday. Precipitation looks to arrive Wednesday evening. We get to do this all over again Saturday afternoon into evening.

The GFS only "slightly" shaved those 18z totals.....

Fingers and toes crossed the Euro is again king!! I am sure the other models are way overdoing the cold! I don't think any of us wants ice!!

18z NAM with snow / sleet and ZR would be quite the messy mix if it was to be believed...

The latest GFS runs has 4 winter events with all but this weekend's event having snow accumulation as part of the mix. This weekend on the model looks like mainly freezing rain changing to rain. Below are the 3 individual model snow events with 2 day totals over the next couple weeks. NOT A FORECAST! The first snow event is this Thursday. #2 is next Wednesday/Thursday and #3 is the weekend of the 14th-15th.

There continues to be an alarming rise in natural climate change deniers!! LOL!

The first model run of the day the 12z NAM which is a bit out of it's range has temperatures here at the surface staying below freezing all day Wednesday and through around 8 or 9am on Thursday. While that is happening warmer air will be moving in above us at around 5k feet. Meaning by about 4am on Thursday morning temperatures will be well above freezing where snow is made. This means whatever falls after that time will be some form of non-snow meaning sleet or freezing rain. Then it will be a race to see how we get the surface to warm for plain rain.

Our 0.3" of snow/sleet and then some freezing fog this morning resulted in multiple 2-hour school delays this morning. This week looks to feature significant fluctuations in temperatures with highs near 50 degrees today and again on Thursday.....but more snow, sleet, freezing rain and plain rain in our future starting on Wednesday afternoon and into Thursday morning. We may get to do the whole wintry mess all over again come Saturday later in the day.

It is back up

As of 830am still a snow/IP mix with 0.3" so far. Season total at 14.8" (2.2" below normal) which is now 87% of normal snowfall through today.

Some light snow just started here in NW Chesco temp is 30.0 high was 30.1 so far...

Agree with Steve....it has been a while likely since 2016 when I have seen ensembles like this...

Wow what great news!!! Promises made - promises kept!!

The 12z Canadian would be not great for the area.....with snow to sleet to plenty of ZR.....

February Climate Records....the 5 feet of snow that fell in 2010 was memorable!

We could see some light snow showers moving through especially Northern Chester Berks Counties late this afternoon into the evening. Some spots may see a coating of snow. Well below normal temperatures today warm to well above normal for both Monday before it turns colder again during the day on Tuesday. This will set the stage for a wintry mess Wednesday PM into Thursday morning. We should see snow overspreading the area with a quick change to sleet and then freezing rain. Warmer Thursday and we turn chillier again by next weekend with another shot of winter weather by Saturday.

Here in the Philly burbs....January of 2025 finished as the 29th coldest first month of the year in 133 years of Chester County PA records back to 1893. The 9.1 degree below zero reading at Warwick Township was the coldest reading in the last 31 years here in Chester County since the 12 below zero at Hopewell/Elverson and 11 below at Coatesville back on January 19, 1994. While we finished with above normal snowfall for the month we also experienced our 3rd driest January behind only 1955 and 1981.
