Weather Roundup: National Forecast for Sept. 11
Overnight storms in western New York spread east on Thursday, with a cool down accompanying it as well. Storms could be severe along the I-95 corridor by Thursday afternoon, particularly the further south you go. Thursday will see a brief warm up with some humidity as well, only for it all to be washed away by evening storms. Temperatures will top in the 70s and 80s in the region (warmer the further south and east you go), before a cool down into the 60s and 70s for the weekend.
Severe storms could overtake a wide swath of the area on Thursday, and Philadelphia, Baltimore, Washington D.C., Richmond, Virginia and Raleigh, North Carolina need to look out for bigger storms potentially during Thursday’s evening commute. A cooler, fall-like air mass seeps in from the west for Friday and the start of the weekend, though showers and storms are likely for much of North Carolina as a front stalls out over the region. Kentucky and Tennessee will enjoy cooler, nicer weather by Friday once the front passes.
Storms arrive in northern Georgia, Alabama and Mississippi Thursday evening in association with a cold front. The front will stall out on Friday, making it stormy along the I-20 corridor, and it shifts eastward for Saturday, meaning lots of showers and storms are likely for Georgia and South Carolina this weekend. A tropical wave could make things unusually rainy in south Florida for Friday and into the weekend.
A cold front, bringing snow and cold air to the Intermountain West, will bring some nice fall-like air to parts of the South on Thursday. Morning lows will range from the mid-50s in the Texas Panhandle to mid-70s in Arkansas and Louisiana. Afternoon highs in North Texas and most of Oklahoma as the cooler air settles in, expect highs in the mid-70s to low 80s in these locations. Further south, ahead of the front, expect another scorching day in Texas; highs will top out in the mid and upper 90s for much of central and southern Texas. Expect hot in muggy conditions in Louisiana as well.
Iowa and Missouri look to get a break from the weather today with generally dry conditions expected. Though areas east into Kansas and Nebraska will see some passing showers thanks to an upper level system sending some moisture and cold air south across the states. The region will start off with temperatures in the 40s/50s/60s with the mildest air across southeastern Missouri. Highs will vary from the 40s/50s across Nebraska to the 50s/60s throughout Iowa with 60s/70s across much of Kansas and Missouri.
A much drier forecast will move in for today, but temperatures will drop drastically. Look for partly to mostly cloudy skies through the day. As the cold front moves out early, lows will range from the 30s in northern Minnesota to the 60s in the southwest. Afternoon highs will mainly warm into the 50s and 60s, with just a few lucky 70s in the south.
Winter Weather Advisories and Warnings will continue in western Montana until noon and in northern Wyoming until 6 pm. Several inches of accumulation and strong winds will make for dangerous travel. Snow and rain will move south into the afternoon and evening. Lows will start off the morning in the 30s. A Frost Advisory is in effect for northern North Dakota as temperatures will likely be around the freezing mark. High temperatures will only reach the 30s, 40s, and 50s.
A ridge of high pressure will build in over Utah and Arizona today bringing nice and dry conditions to both states. The weather will remain a little on the unsettled side though east across New Mexico and Colorado thanks in part to a stalled out front along Front Range and an upper level system. A few rain showers are possible mainly east of the mountains in New Mexico and Colorado with a few snow showers over parts of the Colorado Rockies. Temperatures will start in the 30s/40s in Colorado with morning lows in the 50s/60s throughout Utah and New Mexico. Morning temperatures will vary across Arizona with 40s in Flagstaff and 70s around Phoenix and Tucson. Highs will range from anywhere from 90s across Southern Arizona to 70s/80s throughout New Mexico and Utah with 60s/70s/80s in Colorado.
It looks like another dry day in California and Nevada. That will mean prolonged fire danger in the areas that have seen an enhanced threat in the last week. Overnight lows will drop into the 40s, 50s, and 60s this morning, with 70s in desert areas. High temperatures will be on the warm side. Expect 70s for much of Nevada, up to the 90s and 100s in the south. Temperatures will reach the 70s and 80s along the coast.
High pressure will keep the weather nice and quiet today across the Northwest. Sunshine will rule the region from the coastline to the Cascades to Idaho. Enjoy this late summer weather while it’s around! Morning lows will range from the 40s/50s west of the Cascades to 30s/40s east. Expect cool highs in the 50s/60s east in Idaho with 60s/70s over much of Washington and Oregon. The warm spot in the region today – Southwest Oregon where temperatures will top out in the 90s.
