USNA Weather Forecast
The Baltimore-Washington-Annapolis metro area is entrenched in a heat wave that will likely linger well into next week. Making matters worse, high dew point temperatures over the coming days will result in muggy conditions; expect wet bulb globe temperatures in the upper 90’s and heat index values at or near 100 oF through Tuesday. A weak front will cross the area Friday evening, but will provide little relief from the heat and humidity. Another more powerful front is set to arrive early next week with thunderstorms possible Monday and Tuesday. Looking ahead, Wednesday and Thursday will likely be mostly sunny and seasonable (high temperatures will retreat into the upper 80’s).
Note: No forecasts will be issued July 23 through July 31. For timely weather information during that period, please visit the National Weather Service at www.weather.gov/lwx.
