First, what AI are you using and did you air gap it? Have you found it difficult to maintain? Second, have you found anything significant with respect to short term snowfall forecasting? 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.

ChescoWx Posted yesterday at 01:44 PM Share Posted yesterday at 01:44 PM 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. Link to comment Share on other sites More sharing options...

Mikeymac5306 Posted yesterday at 07:15 PM Share Posted yesterday at 07:15 PM Kinda ironic that Dolly Parton passes and the next named storm is Dolly. Doncha think? Link to comment Share on other sites More sharing options...

ChescoWx Posted 8 hours ago Share Posted 8 hours ago 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. Link to comment Share on other sites More sharing options...
ChescoWx Posted 8 hours ago Share Posted 8 hours ago 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.

ChescoWx Posted 7 hours ago Share Posted 7 hours ago 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 2020's!
