Weather Roundup: National Forecast for Sept. 9

9 Sep 2014, 4:56 am



It’s a pretty clear-cut forecast here – warm and muggy air through Thursday before a strong cold front pushes through, bottoming temperatures towards fall-like levels for the second half of the weekend. A strong cold front pushes through on Thursday from west-to-east, bringing some potentially nasty storms for Thursday in particular. Cooler weather seeps in on Saturday but particularly on Sunday, with temperatures struggling to hit 60 in portions of northern New England and upstate New York.

East Central

A persistent coastal low will continue spinning up moisture into the mid-Atlantic for Tuesday (mainly North Carolina and Virginia), making for more flood concerns in the Virginia tidewater. By Thursday, a strong cold front arrives from the West, meaning strong storms for Kentucky and Tennessee and for everyone else by Friday and into Saturday. Behind this, a refreshing blast of temperatures topping out mainly in the 70s arrives for the weekend.

Warm and muggy air will mostly be the rule of thumb in the region until a cold front arrives on Thursday and into Friday. That system looks like it may stall out over southern Georgia and Alabama, creating stormy conditions there to start the weekend, otherwise temperatures will tumble dramatically for the I-20 corridor. Scattered storms, particularly in southwest Florida and along the I-10 corridor, are likely for Tuesday and Wednesday.

A warm and muggy night across the South, expect low to drop into the low to mid-70s for most of the region. West Texas and parts of Arkansas will be a bit cooler and drier with lows bottoming out in the upper 60s. Tuesday will be relatively dry and hot. Most of the Lone Star State will have temperatures in the mid to upper 90s. San Antonio will be pushing near 100 by late afternoon. That said, a cold front is on the way, highs in the Texas Panhandle will only top out in the low 80s. Much cooler air will filter in, through the next few days.

Central Plains

A system will bring scattered showers and thunderstorms to the region today – especially during the afternoon and evening hours. Some storms may be strong to severe across Iowa, northern Kansas and Missouri, and the eastern half of Nebraska with large hail, damaging wind, and isolated tornadoes are the main threats. Temperatures will start out in the 60s/70s in most spots today. Afternoon highs will range from the 70s across northern Nebraska and Iowa to the 80s/90s for areas south.

Great Lakes

High pressure will be moving out today and rain chances will move in. Showers and thunderstorms will be spread across Illinois this morning. A low pressure system sliding east this evening will bring a chance of strong to severe storms to southern Minnesota, Wisconsin, and northwestern Illinois. A Flood Watch will be in effect from Tuesday night into Wednesday in northern Wisconsin and the Upper Peninsula of Michigan because of heavy rainfall totals. It will push severe storm chances across the rest of the region into the middle of the week. Lows will drop back into the 50s and 60s this morning. Afternoon highs will be in the 70s in the north and the 80s in the south. Look for a major cool down behind the cold front into Wednesday.

High Plains

A low pressure system moving southeast through the high plains will bring a day of shower and thunderstorm chances. Cooler temperatures behind a cold front may even allow for some snow in northern Montana. The region will stay cloudy with a chance of light rain and snow in the west through the middle of the week. Temperatures will drop drastically with this cold front. Lows will be in the 40s and 50s for most locations, with a few low 60s in southeast South Dakota. High temperatures will mainly be in the 50s and 60s. A few spots in the south could hit the 70s, but even cooler air is expected on Wednesday.

Four Corners

Plentiful moisture coupled with an upper level system will keep the chance for showers and storms around much of the region today with flash flooding a possibility for parts of Utah and Colorado due to heavy rain. It’ll be a mild morning for most with lows in the 60s/70s. Expect highs in the 70s across much of Utah and Colorado with warmer highs in the 80s/90s down south in New Mexico and Arizona.

A few scattered storms may linger in the south this morning, but most locations will see clearing and drying into the afternoon. Look for drier air to bring sunshine for the middle of the week. Desert areas will see morning lows in the 70s and afternoon highs in the 90s and 100s. Elsewhere, lows will range from the 40s in northern Nevada to the 60s along the coast. Highs will warm into the 70s, 80s, and 90s this afternoon.

(FORECAST: Las Vegas | Los Angeles | San Francisco | Reno)


Onshore flow will help make for a cloudy and drizzly start for some west of the Cascades in Washington and Oregon including the coastal areas. Some sunshine is possible for these areas later in the day while sunshine will rule the day east of the Cascades into Idaho. It’ll be cool out this morning with lows in the 40s/50s regionwide. Expect highs in the 60s along the coast with 70s elsewhere in Washington, Oregon, and Idaho though one exception will be in Southwest Oregon where highs will top out in the 80s.
