Northeast

Partly cloudy skies return to most of New England today now that the remains of Jeanne have exited well out into the Atlantic. A pesky upper-level disturbance, though, is sparking showers from central and eastern New York to the Chesapeake Bay region. Highs today will be in the 60s, with 70s more widespread south of the Mason-Dixon Line. Once the upper-level system bids farewell to the area as well, the Northeast will be rain free on Friday. Unfortunately, a strong cold front will arrive with rain and thunderstorms for New York and the Mid-Atlantic on Saturday and for New England Saturday night into Sunday morning.

 

South

Abundant sunshine will continue across most of the South today. Scattered thunderstorms once again pop up across the Florida Peninsula. Also, in western Texas, thunderstorms are expected to develop as part of an upper-level trough moves out of the Southwest. Isolated severe thunderstorms are possible with large hail and damaging winds. Highs will generally be in the 80s region wide. Look for cooler 70s across the Tennessee Valley, while the mercury climbs into the 90s in South Texas. A cold front will push deep into the region over the weekend, preceded by scattered thunderstorms.

 

Midwest

From Michigan to Kentucky, high pressure is providing a beautiful day after a cool start. Meanwhile, showers and thunderstorms are on the increase across the Plains. A strong cold front will rapidly blow through the region Friday and Saturday, preceded by showers and thunderstorms and followed by chilly gusty winds. High temperatures across the High Plains on Friday will struggle to get out of the 40s, with 50s and low 60s becoming more widespread across the remainder of the region through the weekend after plenty of 70s today. A second strong cold front will sweep through the region from the Dakotas to the Ohio Valley Sunday and Monday.

 

West

A trough across the Southwestern U.S. will cause another unsettled day across the region today. Once again, showers and thunderstorms will be widespread across the southern and central Rockies. By late in the day, a cold front will begin to dip into Montana. Light showers are possible ahead of this front. After some morning clouds along the coast, you can expect abundant sunshine from Washington southward through California. High temperatures in these areas will be in the 70s, with some 80s. Look for 90s in the Southwest deserts. Cooler highs in the 50s and 60s will linger across the Rockies. A noticeable cool-down will move into the High Plains for Friday.
