HOT today with Severe Threat! Slightly cooler for some tomorrow – More storms later this week


I do think that overall we are in a slow cool down trend and think the worst heat waves are pretty much done this year. That being said, a day or 2 of 90+ temps with high humidity is not unlikely for Northern VA, MD, and PA. Central VA will still have 90+ days as it is just climatology. But, in general, I think we head for cooler temps as a mean. Today is a hot one though! Temps will peak in the mid and upper 90s! Heat indexes will also be in the 100 – 105 degree range. We also have a threat of severe today. Some models had a derecho look to it and caused some alarm yesterday. I am concerned of a line of severe especially South of Fredericksburg down in to NC, or even a Meso Convective Complex (already see this heading to this area on national Radar) . Isolated to scattered strong storms do look possible throughout the region as a front comes through the north areas and and gets hung up in NC. That front will come back up north Thursday and Friday and continue chances for storms after a drier Wednesday for areas of Northern VA, MD, and PA.

Today – we already have a line of racing storms that could come through later this morning in MD and North VA! Quick strong winds and heavy rains could accompany them. As mentioned – HOT!

Tomorrow, for the north will be less humid and a cooler day. Southern half could see some storms.

Thursday, an increase in humidity and storm chances come back. Highs 90s area wide

Friday will feature a better chance of storms across all the region. Highs again around 90 north and low 90s south.

Saturday – More showers and storms possible. Highs 80s to low 90s.

Sunday – Drying up some – highs in the upper 80s to low 90s.

All for now!
