Northeast

Get the umbrellas ready- it’s going to be a wet week for virtually the entire region! A coastal low will drift just offshore from Cape Cod and bring gusty winds and some much-needed rainfall, and it’ll keep temperatures in the 50s for virtually the entire region. The heaviest rainfall looks poised to hit northern New England between Wednesday and Thursday. Things will slowly clear from south to north, and by the weekend sunny skies will rule the weather picture.

East Central

A few showers from the Baltimore-Washington, D.C. region will slowly drift north for Tuesday, Wednesday and Thursday, clearing out by Friday. Otherwise, sunny skies and temperatures in the 60s and 70s will dominate the weather scene. Enjoy the terrific fall weather!

Southeast

More terrific fall weather is in the cards for this part of the country, with the exception of south Florida. Here, a tropical disturbance moving out of the Bay of Campeche (just offshore from Mexico’s Yucatan Peninsula) will move northeast, bringing the potential for flooding rains for Thursday and Friday, particularly for Key West and Miami. Otherwise, calm weather will rule the week in the Southeast.

High Plains

The Dakotas are likely to stay clear and dry today, but a trof of low pressure building in from the west will bring rain and snow to Montana and Wyoming. A Winter Weather Advisory is in effect for parts of western Montana until 5 am Wednesday. Upwards of two inches of slushy wet snow are possible in spots above 6000 feet. Lows will drop into the 30s, 40s, and 50s. The rain and snow will limit highs in the west to the 40s and 50s. Sunshine across the region will bump highs into the 60s and 70s.
