I have added some additionals stations within 3 miles of the Chester County border to enhance our climate data. The support and rationale is included in our latest study on the website. Thanks! https://chescowx.com/chester-county-area-3-mile-rule/

Over the last 25 years Chester County has shown minor but not significant warming....however PHL Airport is as always off to the races with warming.

No data is of course perfect but it is the best historical validated data we have from the time of record

Almost a 20 degree spread in morning low temperatures today within just a few miles across the area this morning. Elevation and terrain impacts.

The minute we put the words scientific and consensus together we know it is fake news!

Today we should see highs from mid 60's in ridge locations to the low 70's in valley spots with lows tonight in the upper 30's to low 40's. It should be one of the better weather weeks of the year with almost no chance of rain. By Saturday morning we should see lows in the low to mid 30's with a freeze possible in the colder valleys! Temperatures will be near normal through Thursday but by Friday we drop to about 5 degrees below normal, before we return to near normal by Sunday. Of note 7 years ago today back in 2019 Chester County was at the start of a 3 day storm that left as much as 1.56" of rain at Coatesville 1E. This was the remnants of Tropical Storm Nestor which tracked within about 190 miles of the county.

We saw 2 stations across the Chesco area record their first freeze. Below is some season lows to date history through today.

With some lower spots with a chance to have their first freezing temperature attached is the average, earliest and latest dates on record.
