Today will be the hottest day of our brief warm up with today reaching the 90's in all areas - maybe even in the higher spots like here in East Nantmeal. This will however be nowhere close to record levels with the mid to upper 90’s record heat for this date set way back in 1962 remaining safe. Tomorrow will be several degrees cooler and may not reach 90 in all areas. Rain chances will be ramping up with an approaching cold front tomorrow later in the day and will continue through Sunday. Some models are hinting at some of the most beneficial rains we have had in quite some time. We turn chillier than normal for the Memorial Day weekend with highs likely to remain in the 50's to near 60 degrees both Friday and Saturday. The area farmers and green thumbs have their fingers crossed even if it could impact some holiday plans.

Charlie you are again misinterpreting the data. The increasing hot years in Philly during recent years is of course the UHI contamination at PHL.

Below is an analysis of when our daily climate records have occurred here in Chester County PA. Temperature, Precipitation and Snow daily records. Of note the decades of the 1930's through the 1950's accounted for 39% of our record high temperature records. The most daily record highs were recorded during the 1940's. The decades of the 1970's through 1990's recorded 40% of all of our daily record low temperatures across the county. With the 1980's recording the most daily record low temperatures. Precipitation wise the 2010's saw the most daily record precipitation records while the 1960's saw the greatest number of daily snow records.

No cherry picking here as fortunately we have climate facts to fall back on - a quick look for example at when many of the records were set in 1936 the 9th and 10th were both 111 degrees at Phoenixville - even eliminating them still has Coatesville and West Chester at 105 and 104 degrees for records still occurring in the 1930's. Surrounding stations were also very hot. Of note the number of hot days across all of PA And NJ is in fact decreasing since the first half of the 20th century not increasing at all!!

A hot start to the week with our warmest day tomorrow before a sharp chill down by Memorial Day weekend. Many valley locations could touch 90 degrees both today and for sure tomorrow. Some higher ridges may fall a bit short of 90 both days. By Thursday temperatures should be at least 20 degrees cooler than Wednesday. In fact, while the current NWS forecast has highs in the mid 60's both Friday and Saturday I suspect much of Chester County will struggle to get out of the chilly 50's both Friday and Saturday. Shower chances increase on Wednesday with shower chances continuing through the weekend.

We will see a brief stretch of above normal temperature days through mid-week before we turn back to below normal temperatures by Thursday and through the Memorial Day Weekend. Many lower valley locations should reach 90 degrees both tomorrow and Tuesday. Higher spots across Chester County will always struggle to touch 90. Rain chances increase by Wednesday PM with the cold front, and it does look a bit unsettled as we move into the holiday weekend.

So tough for the higher spots out here in Chesco to touch 90....but it will be close. Valley spots will certainly get above 90

Not misleading at all simply presenting the actual climate data for the county. You are just as always attempting to explain away the facts but those facts cannot be changed! The above list of when records occurred is actual and real climate data you cannot somehow recast or redo the above data because it fails to fit a narrative.

We start our warmup today peaking with temperatures not far from 90 by Wednesday. A cold front crosses the area later Wednesday with rain chances increasing and we trend back to near normal temperatures by Thursday and below normal temperatures for the start of Memorial Day Weekend.

16 of our last 20 days have featured below average temperatures. Today will be another below average day before we start a strong warmup with temperatures by Tuesday approaching 90 degrees across especially the valley locations across the County. A cold front will cross the area later Wednesday with a chance of some showers. Following that front we should see temperatures fall back closer to normal levels by the end of next week.

Quite the difference my NWS point and click had the warmest being Tuesday and only 87 degrees...Enola has 94 on Tuesday

We picked up 0.44" here in East Nantmeal since last night, Cool and breezy today before we start a nice warming trend. Some lower valley spots may touch 90 by next Tuesday. Higher ridge locations are likely to remain in the mid to upper 80's. We will likely see a return to cooler temps toward the end of next week. Our next chance of rain looks to be toward mid-week.

I actually did just such a deep dive into for example the NWS COOP station at Coatesville 1SW below shows any bias would only have potentially been present from 1910-1921. So not significant based on the 89 years of history for that station.

If modeling is correct certainly no long lasting warmth through June at least

I have compiled the climate averages based on the NOAA calculation of Climate Normals for the philly burbs of Chester County PA for a full year with 30 year averages updated every 10 years. The first base period was from 1901-1930 with our most recent being the current climate base of 1991-2020. You can see our warmest base climate normal occurred back in the 1921-1950 and 1931-1960 periods.
