Some spots today have their first chance at seeing above freezing temperatures. If we fail to reach freezing today it will mark our 11th straight day. This would tie for the 5th longest sub-freezing streak in County history. If we do not top freezing today we have an increasing chance at setting an all-time county record. If we get through next Monday we would set just such a record at 17 days. There were a couple of flurries out there this morning, but we should see some sun this afternoon. Some additional flurries are possible tonight especially across southern areas. A little better shot at some light snow on Friday before yet another strong arctic front sends us back into the freezer for the weekend.

Some very light flurries here in EN temp at 25.2

Same here quite a bit of ice sliding off roof into yard!

One of our mildest morning lows in over 10 days here in Chester County with all stations remaining in the low to mid-teens. Today and tomorrow look like our mildest days over the next week. High temperatures today will be in the upper 20’s, and some spots tomorrow have a chance to reach freezing or above for the first time in 11 days. We turn colder again to close out the work week and will turn significantly colder again by the weekend with temperatures remaining in the teens for highs. We have a couple of minor snow chances this week - the first on Tuesday night and another on Friday.

We start February as we ended January with well below normal temperatures. I am working on completing the overall Chester County summary for January but at least here in East Nantmeal this January was the 4th coldest and 3rd snowiest across the 23 years I have been recording weather observations at this location. This well below normal stretch of temperatures looks to continue for at least the first 10 days of February. Today will be our 9th straight day with below freezing high temperatures. We do moderate through Tuesday with our best shot at getting above freezing being Tuesday. The current NWS forecast has a high here in EN of 30 degrees. There could be a few light snow chances over the next week with the first potential on Tuesday night a more likely shot by Friday and another chance possibly by next Sunday. For those on Team Snow the good news is February is on average our snowiest month of the year with East Nantmeal averaging 13.3" of snow in a typical 2nd month of the year.

Agreed! I had 0 or below last 3 nights but last night was lowest at 2.8 above....that said valley spots were well below zero

A weenie view of a classic it's coming north radar hallucination. Who else is feeling January 2000? coming north.mp4

ICON with a little snow across the area on Wednesday

A few places touched zero this morning including the icebox of Chester County the Warwick DEOS station that set an all-time record low with records back to 2012 of 10.7 degrees below zero. The old record was 9.1 below zero on January 22, 2025. Our impressive cold stretch continues through the weekend with today being our 8th straight day of sub 32 highs. This is tied for 8th longest streak since 1893. Our best chance to end the streak and get above freezing looks to be on Tuesday with the NWS forecasting a high of 30 degrees. January will end as our 4th consecutive below normal temperature month and our 9th below average month in the last 12 months dating back to December 2024. Could we be entering our next climate cooling cycle here in Chester County?? While cold most of the next week looks dry but there could be a couple chances of some snow toward midweek and again next weekend.

Don!

Agreed great guy!! like you enjoyed his info since the early days of the forums!!

Assuming you were joking above Birds? We all make mistakes even Don LOL!! Take it easy on him!! Even I have made a mistake on Chester County weather!! LOL!!

Hey Don think you have your dates wrong nothing unusually cold at PHL in that timeframe. The most days below freezing in a row during Dec 09 - Jan 10 was only 3 days

But in our current warm cycle it is quite amazing IMHO!

So, with just 2 days left in the month I did a quick analysis to put into perspective how cold these first 2 months of the winter season have been across the Philly burbs of Chester County. This January is on pace to be a top 26 all-time cold January across 133 years of climate data since 1893. It is also our coldest first month of the year since 2014 It will also be a Top 20 all-time cold December/January start to winter. Plus, our coldest start to winter since 2010-11.

It looks like all stations across the area remained in the single digits above zero with Warwick Twp. our normal cold spot at 2.0 above and of note here in East Nantmeal our low this AM was 3.3 above - this is my coldest reading here since the 3.0 degrees last January 22nd. Today and tonight looks to be a couple of degrees colder than yesterday. We stay in the teens for highs both today and tomorrow before we finally crack the 20-degree mark on Sunday. We see a slight moderating trend through the middle of next week with highs possibly approaching 30 degrees by Tuesday. We could see some snow chances by next Wednesday into Wednesday night. We may turn even colder again by next weekend. The long-range models continue to think while we might get close for a couple of days....they have no days reaching the 32-degree mark through at least mid-February!
