USNA Weather Forecast

Forecast Discussion:

High pressure along U.S. East coast this morning will allow for sunny and seasonably warm conditions for U.S. Naval Academy Graduation! The High will become entrench offshore by Friday evening with warm and moist southerly flow develop throughout the forecast period. Separate weak disturbances will pass on Saturday and Sunday. With the moisture rich air mass already in place, scattered slow moving showers and thunderstorms are likely both days in the afternoon through the overnight hours (although not widespread). Isolated storms could contain heavy rainfall. The National Hurricane Center has indicated there is 90% chance of tropical cyclone develop in the Gulf of Mexico this weekend. The latest ECMWF/European and GFS/American models suggest landfall of the tropical system is possible between Sunday night and Tuesday morning. The tropical system is expected to move slowly (and perhaps stall) along the Gulf coast, however the area of high pressure off the U.S. East coast will help funnel tropical moisture northward early next week. Therefore, rain chances remain in the forecast on Monday and Tuesday. Also note that the dew point temperature, and therefore the humidity, will remain elevated Saturday through early next week.

Note: Due to Memorial Day on Monday, May 28 (federal holiday), the next forecast will not be issued until May 30. For updates over the weekend, please visit www.weather.gov/lwx.
