Philadelphia Weather Discussion- Thur PM
Well, we've had some pretty wild weather this past week. I think what stands out in my mind most is how poorly the models have been at predicting several of the events in the current weather. The best example is last Friday's derecho thunderstorm complex. None of the models had predicted even a high chance of thunderstorms Friday night and the chance of severe weather was predicted to be very low as well.
Regarding the current heat wave, all of the models had a cooling trend to occur this past Tuesday; then the front was supposed to cool things down on Thursday (today). Now, the front is supposed to move through Sunday night. But will it?
The models are now predicting a greater pattern change for next week, where a cyclonic flow in eastern Canada, an extension of the polar vortex, will move the front through and maintain cooler temperatures. This change had been predicted to occur this week. We will see if this happens.
