Discussion
After a cool start to the week, it’ll turn slightly warmer today and then uncomfortably warm and humid for Wednesday and Thursday with highs in the 90’s on the table by Thursday afternoon. The warm-up at mid-week comes ahead of a strong cold front and both Wednesday and Thursday can feature strong-to-severe thunderstorms during the PM hours.
After backing off a tad on Friday, temperatures will surge around here from later this weekend through the middle of next week with a run to 100 degrees possible in the big cities all along the DC-to-Boston corridor. Very strong upper-level ridging which has been largely confined to the western states in recent days will push to a position centered over the eastern states by early next week and temperatures will respond in a dramatic fashion.
