Dry, breezy and sunny until ...
Sunday's storms marked the passage of the cold front that has brought us this bright, sunny and dry weather for the bulk of this week.
The high-pressure system pushing in on north winds will mean very pleasant weather for the mid-Atlantic through Thursday morning. Chances for some showers and thunderstorms return Thursday afternoon with the next cold front, and those chances will grow through the weekend as Hurricane Irene approaches.
The National Weather Service regional forecast office in Sterling is predicting highs in the low 80s Monday and Tuesday. In between, overnight lows may dip into the 50s Tuesday morning, and the 60s in the cities. By Tuesday night, Wednesday morning, we could record some lows in the 50s in the urban corridor, too.
In the meantime, forecasters along the East Coast are watching the progress of Hurricane Irene. Some additional weather balloons will be launched this afternoon at Sterling to support the effort. For now, here's what the local forecasters are saying:
"With most of the medium to long-range guidance taking Irene roughly up the Atlantic coast from the Florida peninsula to New England, will watch the progress and trends in the coming days. Irene, according to latest runs of these models, may affect the easternmnost sections of the [forecast area] Sunday into Monday of the coming weekend, early next week.
"The synoptic pattern over the Great Lakes, New England under this type of scenario would give the tropical system a bit of an opening to make this northerly trek up the coast..."
AccuWeather.com is predicting landfall Saturday night in the Carolinas.
Word to the wise: If your sump pump is ailing, or your storm drains are clogged, this week will be a great time to get them fixed and ready to flow.
