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 for the Mid-Atlantic region and it’ll persist into the upcoming holiday weekend. Temperatures can reach or even surpass the 100 degree mark during the second half of the week for afternoon highs and humidity will be at very uncomfortable levels as well. Intense upper-level ridging of high pressure will be a key player during this heat wave as it becomes centered over the Great Lakes for a several day period and influences the entire DC-to-Boston I-95 corridor.
