Discussion

The turn of the calendar on Wednesday from June to July will come with the arrival of the hottest weather of the year so far and it’ll persist into the upcoming holiday weekend. In fact, temperatures can reach or even slightly surpass the 100 degree mark for afternoon highs during the second half of the week and humidity will be at very uncomfortable levels as well. Intense upper-level ridging of high pressure will be a key player during this upcoming heat wave as it becomes centered over the northeastern states for a several day period and influences the entire DC-to-Boston I-95 corridor.
