Brian's exclusive forecast for Annapolis: Mostly sunny and hot again today with highs in the mid 80s to near 90 degrees. Becoming mostly cloudy overnight and unseasonably warm with lows in the low to mid 60s. Mostly cloudy on Monday with widespread rain showers. Humid, but not as warm, with highs in the upper 70s. The outlook for Tuesday calls for clearing conditions and windy at times with highs in the low to mid 70s. Sunny, cooler, and less humid on Wednesday with highs in the upper 60s to lower 70s and overnight lows in the mid 50s.
At 8 a.m., temperatures and dew point values this morning are more reflective of weather in August than in the first week of October with current readings in the upper 60s to near 70 degrees. By later this afternoon, we will experience temperatures in the mid 80s with a few locations reaching the upper 80s. High pressure off the eastern seaboard will ensure a warm, moist, southerly flow of air over the region through this afternoon. Meanwhile, a vigorous cold front will push from west to east across the bay on Monday. Moisture streaming northward in advance of the front will produce widespread rain showers and scattered thunderstorms over the Chesapeake. With the ground hardened by the recent dearth of rainfall, heavier showers may produce localized flooding. Current indications are that some areas may receive in excess of one inch of rainfall, or more, in a six-hour window Monday afternoon. In the wake of the front, much cooler and drier air will overspread the region on Tuesday and Wednesday with highs dropping from the low to mid 70s on Tuesday into the upper 60s on Wednesday.
