Forecast Discussion
No change to the forecast reasoning. An extended period of southwest steering flow is expected over the next week, which typically favors the eastern half of the peninsula for afternoon showers and thunderstorms. While coverage is forecast to be a bit less this weekend, precipitation chances are expected to increase again next week as a mid- and upper-level trough develops over the eastern U.S. Given the pattern on Tuesday, the greatest coverage of convection is expected to hold off until after the launch window. Still, a weather-related violation is possible due to isolated showers and thunderstorms in the area, particularly towards the end of the count. The primary concerns at this time are the Cumulus Cloud, Surface Electric Fields, and Lightning Rules.
