OK, we are a wake up away from the first 90+ day of the year and the hottest temps in nearly a year! The October Nor’easter turned out to be the biggest snowstorm of the Winter and this early heat blast may end up being the hottest of the Summer…it means business! In fact, the National Weather Service has already issued a Heat Advisory for the area tomorrow, heat and humidity will create dangerous conditions for anyone working outside for a long duration so take it easy.
So how hot will it be? With an offshore wind and exceptionally warm temps aloft, we are looking at highs of 95-100 both Wednesday and Thursday. The only thing that would prevent us from getting to such lofty numbers would be some renegade clouds or a sneaky seabreeze. Both, at this time, do not look likely to occur so we will end up baking from the Berks to the beaches. Boston will challenge the record high of 98 degrees tomorrow and will pass the record of 95 on Thursday. There will be heat, there will be humidity, but there won’t be much of a trigger for widespread thunderstorms. Any that develop will be isolated in nature and would likely occur over hilly terrain.
By Friday, a coldfront will be getting into the picture this will lead to scattered showers and thunderstorms in the afternoon, some could be strong, and as a result temps will be less hot…closer to 90. Still, some towns will have their first official heatwave of the season.
The front now looks like it will get hung up over us to start the weekend…this will delay the clearing and drier air. With a wave of low pressure spinning up along the front, showers are likely too…an unsettled start to the weekend. The wave will pass in the afternoon and more comfortable air will work Saturday night leaving us a solid Sunday with a mix of sun and clouds, highs near 80 and just a small chance of a late day t-storm.
