Tonight will be quiet and comfortable across the Tri-State, with mostly clear skies, a light east wind, and temperatures dropping into the upper 50s. That cool feel won’t last long.

On Tuesday, high pressure that has been keeping us dry moves east, allowing warmer air from the south to surge back into the Tri-State. Sunshine dominates, and temperatures leap all the way into the low 90s. Tuesday night stays much warmer, with only a slight chance of a shower toward daybreak.

Wednesday and Thursday continue the hot pattern, with highs reaching the low 90s. The reason is a strong area of high pressure building across the southeastern states, pumping warm and increasingly moist air northward.

At the same time, the main storm track begins slipping south toward us as a front drops over the area. That introduces occasional chances for showers and thunderstorms Wednesday through Friday. The atmosphere will become increasingly unstable and moisture-rich, so while some severe weather may be possible, repeated rounds of storms and the resulting flood threat could become the bigger concern.

The front should finally move south of the region late Friday into the weekend. Friday remains warm, with highs in the mid 80s. Saturday looks mostly sunny and stays in the low 80s before another chance for showers arrives Saturday night. Sunday becomes partly sunny with scattered showers possible and temperatures easing to near 80 degrees.
