ChescoWx

A nice weekend ahead with increasing sun today and continued below normal temperatures through the weekend. We warm to above normal highs in the mid to upper 80's by Monday lasting through Wednesday we then fall back to a bit closer to normal by the end of next week. Next rain chances look to be toward Tuesday.

The latest ChescoWx Forecast now has 1.34" of rain by midnight tonight at East Nantmeal.

We had a brief shower this morning, but showers will become more widespread later this afternoon and into the night with the ChescoWx model predicting 0.44" of rain by midnight tonight. We start to clear up tomorrow and start a steady warming trend with our peak warm days looking to be next Monday and Tuesday. However, any 90+ days look unlikely especially for the ridge locations. I suspect we have already seen our last "heat wave" across the county.

Fox 29 in Philly posted the below graphic for Philadelphia at the PHL Airport regarding "heat wave" days. I have also posted the same analysis for Chester County since 2020. Of note 10 of the Chester County stations have had the same or less than the 7 heat waves at PHL this year over the entire decade of the 2020's!

For those interested in the very early accuracy of the ChescoWx model forecasts vs. the NWS - so far with a couple complete days all model runs ran cooler than the NWS Forecast and the actual verified temperatures were cooler than the NWS Forecast with ChescoWx at least over a couple full days being closer to the actuals. But it is only a couple of days so we will keep tracking. The first column is the forecast run time with the green shaded being ChescoWx and the unshaded column the NWS forecast.

One more great day before we see the return of some showers and maybe a t-storm tomorrow. Our ChescoWx forecast keeps us in the mid to upper 70's for highs each day through Sunday before we warm into the mid to upper 80's by both Tuesday and Wednesday next week before we cool down again by the end of next week. Some valley spots could certainly see some 90 degree temps for a couple of days but any extended heat wave is unlikely.

Widespread low to mid 50's across the county this morning with the lowest the 51.2 at Warwick. Another beautiful day on tap today with highs per our ChescoWx Model in the mid 70's with the NWS seeing upper 70's. The NWS sees 80's starting tomorrow through the next week while ChescoWx keeps East Nantmeal just shy of 80’s both tomorrow and Thursday before falling back to the mid 70's both Friday and Saturday. Rain chances to increase by Thursday before we clear out on Friday.

Hey Joe - I am using Claude which does not run locally so no air-gapped environment. Regarding snow I just started the model up 3 days ago so we will see when we get to winter.
