Some large temperature spreads this morning across the area with lower valley locations like Warwick Township with a low at 25.8 degrees while higher spots like here in East Nantmeal could go no lower than 35.7 degrees. Our mild weather continues through Saturday before we turn back to temperatures not too far either side of average for January by Sunday and through much of next week. We have rain chances increasing by later tomorrow and lasting till toward midnight on Saturday night. This could be one of our more significant rain events in the last few months with some models hinting at over an inch of rain. Looking further ahead it appears likely we turn significantly colder by next weekend but at this point no significant winter events are on the horizon. For those on Team No Snow fingers crossed it stays that way!

Does the Wiggum rule require that reading at PHL airport?

A nice January thaw day on the way although a bit breezy with highs well into the 40's. Even better weather tomorrow with sun and less wind. Shower chances increase Friday and into Saturday which will mark the end of our very brief milder period. We turn back to colder during the day Sunday and we should see normal January temperatures returning for much of next week. We may also start to see some potential for more wintry weather as we move toward the end of next week.

Suspect the rain will exit stage right well before kick off - bigger deal IMO will be the wind....

Today we should be seeing the temperature warming to near normal for early January with highs in the low 40's. We could see some light rain later this evening and into tomorrow morning. We then start a stretch tomorrow with above normal temperatures for the next 4 days through Saturday before we chill back down to normal temperatures to close out the weekend and will stay seasonably chilly all of next week.

February 2010 was the snowiest month I have personally experienced in my life time. Over 5 feet of snow with 3 storms over a foot. Including 26.8" / 18.3" and 13.5" over just 3 weeks!

While the 2020's are less than our last very snowy 2 complete decades - we will likely not see such low totals as the true snow drought years back in the 1930's through 1950's and again in the least snowy decade the 1970's....simple cyclical weather patterns - rinse and repeat!!

Below are the top 25 January Snowstorms across the philly burbs of Chester County since 1893 - of note 5 of the top 25 have occurred since the year 2000.

This is a top 25 coldest 1st 5 days of January here in Chesco with 135 years of climate data.

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.
