Weekend Weather Outlook
UPDATED 9 AM EDT, September 14, 2013

The Eastern U.S. hot streak will finally be ushered away for this weekend, in favor of a much-anticipated autumn cool-down. It will be a different story across Florida, far southern Texas, and from the West into the Plains, where summer weather including downpours, thunderstorms and tropical trouble will stir.
WeatherBug Meteorologist Addison Green has the latest in this exclusive WeatherBug National Outlook.
Those across the Eastern U.S. headed to college football games will not only be able to enjoy a deep blue sky, but will also welcome a reprieve from the recent heat and high humidity. It will feel fall-like from the Upper Midwest, Ohio Valley, and Great Lakes into the Mid-Atlantic and New England. Here, the mercury will only top out in the 60s and low 70s, with New England not climbing out of the 50s.
It will be warmer from the central and southern Plains into the Carolinas and Florida, where 70s, 80s and a few very low 90s will be common. Added to the mix will be a few late-day showers and thunderstorms that could send a few outdoor plans indoors.
Meanwhile, the weather will be anything but cooperative across the Desert Southwest, Mountain West, and western and northern High Plains. A push of monsoonal moisture and a broad low pressure system will trigger widespread shower and thunderstorm activity from Arizona to Minnesota.
Temperatures will climb into the 70s and 80s from the Southwest to the Upper Midwest, with toasty 80s and 90s commonplace along the West Coast while basking in plenty of sun. The immediate West Coast is the only place that will escape the heat, with 60s and very low 70s expected.
The Eastern U.S. will see a near carbon-copy of today`s weather, with the lone exception being along a cold front carrying a few nuisance showers and a possible rumble of thunder from the Great Lakes into the central Plains.
Additional showers and thunderstorms will also drench Florida and the Gulf Coast, while a tropical low in the Gulf could spread squalls of very heavy rain and gusty winds into far southern Texas. Cities such as Brownsville, Corpus Christi, and Alice, Texas, will need to have umbrellas and rain gear handy on Sunday.
Temperatures will also be similar to today, with highs along the Northern Tier topping out in the 50s, 60s, and lower 70s. Warmer 80s and 90s will be common from the central and southern Plains into the Carolinas and Florida despite an increase in tropical downpours and thunderstorms.
The Northwest, Mountain West, and Desert Southwest won`t be able to escape its recent soggy stretch of weather on Sunday. Outbursts of rain and embedded thunderstorms will certainly put a kink in those afternoon outdoor plans from Washington and Oregon to Colorado and New Mexico.
Temperatures will again top out in the 80s, 90s, and lower 100s along the West Coast where sunshine will dominate. Elsewhere, it will be 60s and 70s for highs on Sunday across the Western U.S.
