Discussion

High pressure in the upper part of the atmosphere will expand to the Mid-Atlantic region today from the Northern Plains leading to hotter weather around here for the next few days. In fact, temperatures are likely to reach 90 degrees today, and then peak well up in the 90’s on Wednesday – likely the hottest day of the week. The next few days will generally be relatively quiet in terms of precipitation chances though an isolated thunderstorm or two will be possible. More widespread unsettled weather returns at the end of the week and during the early part of the weekend with the approach of a cold frontal system. This unfolding pattern for the early part of the weekend could result in a heavy rain/flash flooding threat for the Mid-Atlantic region and possible strong-to-severe thunderstorms.
