Another pleasant day is on tap for today. Low humidity and temperatures a bit higher than yesterday will make for a nice day. Wind will be a lot less of an issue today with only light winds across the area. Enjoy today...tomorrow will mark a return of warmer and significantly more humid conditions.
By tomorrow morning, dewpoints will be on the rise as they head up to the upper 60s and potentially even the lower 70s. This type of humidity is quite uncomfortable. Highs tomorrow will be well into the 80s. The humidity will make it feel like it is even warmer as well.
During the afternoon and evening, there is a chance of thunderstorms across the area. However, the various computer models disagree significantly on the coverage of thunderstorms. The best threat for storms (potentially severe) will be well north of the area into Pennsylvania and New York state. However, storms will also be possible across the DC/Baltimore area. IF storms do form and move across the area, the ingredients are in place for a potentially significant severe weather event. Again, best odds being to the north.
There is an "Enhanced" risk for severe storms outlined by the NWS Storm Prediction Center for extreme Northern Maryland and Pennsylvania. A lower risk is in place for the rest of the area. Large hail and damaging winds would be the primary threats.
