ChescoWx

Not a huge believer in even the ensembles at 5 days....I will be more interested in this thread the needle potential if they start to show something at 12z tomorrow.

18z GFS with a Chesco Special..... book it dano!

A needed wet day ahead with rainfall amounts approaching an inch in some lucky areas. It will be chilly with temperatures in the upper 30's to lower 40's. The sun returns tomorrow but don't be surprised if you see a couple snow showers around before the Eagles game at 430pm. Temperatures will be seasonably chilly this week with the exception of Wednesday which looks to be well into the 40's to near 50 for highs before we turn much colder to end the week. There will be increasing chances of some wintry events at some point late this week and early next week.

The 6z GFS before it dissapears at 12z

Plenty of storms and rumours of storms coming up....give me the cold and one of these waves will sharpen just enough for a winter "event" or 2....

Mild temperatures continue today with rain chances increasing this afternoon. A brief break in the rain tonight before we turn chillier with more rain tomorrow into Saturday night. Temperatures turn colder after Sunday with temperatures not too far from normal for mid-January before trending much colder by the end of next week into the weekend. We could see between 0.75” to 1” of rain tomorrow night. Winter weather opportunities start to ramp up by later next week.

valley spots around me were in the 20's but mid 30's here

Some folks had asked me to perform an analysis of both the Winter and Summer Average Temperature by Complete Decades for just here in Chester County from the 1900's thru the 2010's. You will see the very cyclical nature of our warming and cooling patterns. Overall, we have seen some slight warming of winters and conversely some cooling of our summers across Chester County PA. The warmest decade for both summers and winters was way back in the 1930's. Of note so far here in the partial decade of the 2020's we are so far running as the warmest winter decade since the 1930's!! However, last winter was the coldest winter in 10 years and we are off to a colder than normal start to this winter so we will wait and see if this is the start of the next cooling trend across the County. These are also updated on the http://www.chescowx.com website. Let me know if you have any questions.

Have not hit freezing here the last 2 nights- tonight will be our 3rd straight....

Thanks Kevin! it's my original training and early career as an accountant that makes me like to play with numbers

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.
