Well, it is that time of year again. July is supposed to be a month of hot temperatures. It looks like New England will be in store for an impending heat wave by the time Wednesday rolls around. Before we can look forward to this though, we have to get through a potentially unsettled Monday.
We will see one more nice day on Sunday before the threat for thunderstorms and potentially significant heat arrives from Monday onward. It appears at this time, we will see a cold front drop southeast out of southern Quebec on Monday morning. This will serve as a trigger for shower and thunderstorm development Monday afternoon. There is the concern for thunderstorms to reach severe levels on Monday. The possibility exists for storms to produce large hail, damaging winds, heavy rain, and even an isolated tornado Monday afternoon and possibly into the evening. The region of greatest concern looks to include all of New England (I think risk increases with southward extent due to the timing of the front), as well as New York for points north of New York City. This cold front should drop south of New England into the Mid-Atlantic overnight Tuesday, posing no severe threat to the region on Tuesday.
The severe weather threat on Monday takes a back seat to what's in store for Wednesday and beyond. Potentially the most potent heat we have seen all summer will invade New England for the second half of the week into the weekend. Unfortunately, we will not receive any breaks in the humidity department. Humidity levels will become unbearable, especially from Thursday onward. This early in the week, I would not be entirely surprised to see minimum heat advisory criteria heat overtake a large portion of the region, particularly inland Southern New England as temperatures soar into the 90's. With this heat, air quality will rapidly deteriorate, meaning any person with a respiratory condition may want to consider postponing any strenuous outdoor activities they may have already planned. I will continue to monitor this potential as we move closer to Wednesday.
Check back later for more updates!
