Unsettled But Not As Toasty
It's been a stormy night down by DC as a few to several inches of rain have fallen across the Mid Atlantic. Flooding is occurring in a number of places down there this morning as slow moving thunderstorms have dumped a ton of rain. With an upper level disturbance over the Mid Atlantic today, the potential for bands of showers and storms to fire up later, pivoting off of the Atlantic, and moving through the region. Odds favor south of the city seeing a bit more thunderstorm activity than north.
Any of those showers could (operative word) produce heavy rainfall, especially if we get any level of sunshine and destabilize the atmosphere.
Temperatures today will be held down a bit further by the presence of those clouds. We're expecting highs barely above 80 degrees in the city and points south, perhaps only in the upper 70's to the north. Humidity levels will be pretty high -- dew points generally in the mid and upper 60's -- so it will still feel a bit muggy out. Winds will be light from the north and northeast.
We do foresee a slow warmup in the weather through the course of the weekend. Guidance does suggest a run at 90 by Sunday and another stretch of 90+ heat for several days next week as high pressure builds in over our region.
