Today and tomorrow look to be our last below normal temperature days for almost a week. This week will be a welcome but likely brief break from wintry temperatures. The warmest days look to be next Friday and Saturday with highs in the low to mid 50's. Those days also look to feature our next best chances of some rain. There is a slight chance of some light snow or flurries tomorrow morning.

I have zero issues with folks posting long range models as sometimes they are onto something and as I always tell folks on my FB page....the good news is we never have to shovel or scrape even one run of model snow! I know folks on this forum understand what a model is and what it is not. That said on my FB page I always qualify any model post with NOT A FORECAST! This helps folks understand it is not hype, it is not a forecast it is simply one tool of many in the professional meteorologists tool box to make a forecast. A model can never replace a professional meteorologists forecast! I also do not believe as Albedoman says "they are ruining the reliability of the forecasters on this site". Professional forecasters and our NWS are not harmed by posting models that will never actually occur. They our NWS are the only true resource for real forecasts!! Imagine if we actually had to shovel or plow the amount of model snow output by these models the last 2 winters? If so my blower would have been broken long ago! LOL!!

Below is the 2025 Climate Summary for Chester County PA

Below is the 2025 Chester County PA Climate Summary

If you think we were running colder than normal the entire holiday season you are correct. In the 37 days since Thanksgiving day 31 of those days have featured below normal temperatures. We should have another 3 days of below normal temperatures before we finally see an above normal temperature day on Tuesday. In fact, that day should begin a streak of well above normal temperatures that should last for about 6 days before we look to potentially trend back to below normal by next Monday. There is a slight chance of some flurries tonight with our next rain chance arriving by Thursday night.

Still crunching the annual climate numbers for the other Chesco stations but at least here in East Nantmeal our average temperature for 2025 was 52.4 degrees this is the 5th coldest year in my 22 years at this location and the coldest since the 51.7 in 2013.

As I had mentioned yesterday some models were hinting at some snow showers overnight and we did indeed see some overnight which as many have mentioned recoated drives across the area. Here in East Nantmeal we picked up 0.3" of snow. We continue with well below normal temperatures through Monday but then see a nice warmup with temperatures trending well above normal for much of next week. Overall the next week or so looks dry with maybe a snow shower chance Saturday night.

Light snow here in EN at midnight temp 19.0 DP 9.0

Indeed - technically out here in Chesco our average snowfall is 35" so in 66% of these seasons we finished with above normal snowfall....so the trend is your friend!!

With our 7th winter "event" of the season we are now at 12.5" of snow for the seaon to date. This is 175% of normal snow through New Years Day. This is in fact the 17th snowiest start to a winter season here in the philly burbs of Chester County PA. Below are the 36 seasons with at least 10" of snow through New Years Day with the ending snowfall for the entire winter season. There is a high correlation to above normal snowfall with such a relatively "snowy" start to the winter season.
