Heatwave soon?

The cold front that was projected to be stalling across or just south of our region by the model guidance this week moved much further to the south, allowing for some pretty tranquil afternoons overall. We did have a few isolated thunderstorms on Tuesday. Today, we did not have any thunderstorms. We did have some cumulus clouds today.

The front will return as a warm front. As it does so, thunderstorms, isolated, are possible Thursday and Friday. The front will be driven by a low pressure center in the Great Lakes region (a familiar site this year) and it will drive a cold front towards New Jersey on Saturday and Sunday. The one problem is the front will never move through our region through Memorial Day weekend. Therefore, afternoon daytime heating could spark scattered showers and thunderstorms. It could also get quite hot ahead of the cold front, especially the latter half of Memorial Day weekend. It will not be until the middle of next week that a cold front actually swings through our region. It is possible that some areas see three consecutive days of 90 degree weather which means a heat-wave is not out of the question starting Sunday and lasting into Tuesday or Wednesday. This is considerably different from the model projections earlier in the week which showed the weekend cold front pushing offshore allowing for cooler air.
