Weather Roundup: National Forecast for Sept. 23
Beautiful weather will be the rule for much of the week, with highs in the 70s and sunshine for virtually everyone all week long. Northern Maine could see a spot shower on Tuesday, but the next widespread chance for rain comes on Thursday in association with a coastal low. Right now, it looks like a fairly potent coastal low could bring a rain day for southern New England and Long Island – potentially including New York City – for Thursday. We’ll keep you updated on this as the week wears on, but for now plan on rain in southeast New England (Cape Cod, Rhode Island, eastern Connecticut and Long Island) for Thursday.
Dry and beautiful weather will, much like the Northeast, rule the skies here as well. A developing coastal low brings rains to North Carolina and the Virginia tidewater for Tuesday and Wednesday, but the low’s track will make it a close call for rains in the Delmarva and coastal New Jersey on Wednesday and Thursday. But, the story will undoubtedly be fantastic weather, with sunshine and temperatures in the 70s and 80s, for everyone else virtually all week. Enjoy!
A coastal low looks set to deliver rains to the coast of Georgia and South Carolina for Tuesday, but all-in-all we’re looking great in the region the next few days! Fall starts with temperatures on the crisp side, particularly from I-20 on northwards, but sunshine will be out in full force most of the week. The one predictable exception is central and south Florida, in line for afternoon showers and storms as always. The best chance for storms here comes on Tuesday as a frontal boundary lifts through.
Parts of West Texas will continue to see rain through the morning hours, elsewhere across the South expect mostly dry conditions. Morning lows will range form the low 50s in central Arkansas to low 60s in the DFW Metroplex to mid-70s in south Texas. Expect dry conditions in the afternoon with highs in the low to mid-80s.
An upper level system will bring a chance of scattered showers and storms to much of Kansas, Nebraska, and Iowa today while much of Missouri looks to remain dry. Expect morning lows in the 40s/50s regionwide as temperatures look to warm into the 70s in most spots this afternoon. A few locations across western Kansas and Nebraska will see highs in the low to mid 80s with a few spots in the eastern Nebraska including Omaha seeing highs in the 60s.
Cool conditions are going to continue to be the story for today. Most of the Great Lakes will see ample sunshine today. In some areas in the northern portion of the region there will be more of a chance of some pesky clouds. High temps will range from the mid 70s to the upper 60s. Story changes though on Wednesday as rain chances begin to increase for the western edge of the Great Lakes, but the eastern half should expect another day plentiful sunshine.
A trough of low pressure moving east will bring a chance of scattered showers and thunderstorms to the Dakotas. Other than a few showers in the higher elevations of western Montana, the rest of the region should remain dry. The morning will start off with lows in the 40s for the west and the 50s everywhere else. Where sunshine prevails, highs will reach the 70s and 80s. Locations seeing cloud cover and rain will be stuck in the 60s.
A ridge of high pressure will build back in across the Four Corners region today bringing warm and dry conditions to much of Utah, Colorado, and Arizona. New Mexico though will continue to see scattered showers and thunderstorms through the day today. Morning lows will run from the upper 50s to around 60 degrees in cities like Denver, Albuquerque, and Salt Lake City to the 40s in Flagstaff and the 70s in Phoenix. Expect highs in the 80s from Denver into Grand Junction over to Salt Lake City. Highs down south will range from around 100 degrees in Phoenix to the 90s in Tucson. Flagstaff looks to top out in the 70s today with a high in the 80s in Albuquerque.
A clear and dry pattern returns to California and Nevada. The only chance for cloud cover and rain will move in off of the northern California coast late Tuesday into Wednesday. With dry fuels on the ground and lightning potential with storms, a Red Flag Warning is in effect this afternoon through Wednesday for a handful of counties in that area. Expect lows in the 40s in northern Nevada, 60s along the coast, and 70s in desert cities. Afternoon highs will warm into the 70s, 80s, and 90s. The desert is likely to see triple digits.
An approaching storm over the Pacific will bring rain across western Oregon and Washington mainly late today as clouds look to increase early in the day ahead of the system. Idaho looks to remain generally dry today. Temperatures this morning will generally be in the 40s/50s with a few isolated spots like Portland and Boise starting the day off around 60 degrees. Much of the region today will top out in the 70s/80s though coastal locations will see cooler highs in the 60s.
