An area of high pressure will become entrenched off the Southeast U.S. coast for the remainder of Commissioning Week. This is a typical “summer time” pattern with southerly flow ushering in warmer temperatures and an increase in the humidity. Expect high temperatures in the mid 80’s this week with the dew point temperature (measure of how much moisture is in the air) increasing from a comfortable 51 oF as of 0600 on Wednesday morning to a sticky 68 oF by Friday afternoon. Sunny skies will prevail on Wednesday, with partly cloudy skies Thursday and Friday. The increase in humidity on Friday could create some air quality issues, as well. The heat index on Thursday and Friday is expected to approach 90 oF.
The increase in temperatures and humidity will also result in a less stable atmosphere. Scattered pop-up showers and thunderstorms are expected to develop across Maryland late Thursday afternoon/evening. Any Bay Breeze could enhance storms chances. By Friday, isolated pop-up showers and thunderstorms could begin to develop by noon across the Mid-Atlantic region, with chances increasing throughout the afternoon/evening. There will not be a coherent front or weather feature associated with these storms; if they develop, they will be purely pop-up in nature and difficult to forecast exact timing/location. The figure below shows the scattered, pop-up showers and storms developing on simulated radar (4km high res NAM model) Thursday and Friday.
