Weather Roundup: National Forecast for Oct. 21
Get the umbrellas ready- it’s going to be a wet week for virtually the entire region! A coastal low will drift just offshore from Cape Cod and bring gusty winds and some much-needed rainfall, and it’ll keep temperatures in the 50s for virtually the entire region. The heaviest rainfall looks poised to hit northern New England between Wednesday and Thursday. Things will slowly clear from south to north, and by the weekend sunny skies will rule the weather picture.
A few showers from the Baltimore-Washington, D.C. region will slowly drift north for Tuesday, Wednesday and Thursday, clearing out by Friday. Otherwise, sunny skies and temperatures in the 60s and 70s will dominate the weather scene. Enjoy the terrific fall weather!
More terrific fall weather is in the cards for this part of the country, with the exception of south Florida. Here, a tropical disturbance moving out of the Bay of Campeche (just offshore from Mexico’s Yucatan Peninsula) will move northeast, bringing the potential for flooding rains for Thursday and Friday, particularly for Key West and Miami. Otherwise, calm weather will rule the week in the Southeast.
A cool and dry morning is on-tap for much of the south as lows bottom out in the mid-50s to low 60s for much of the region. A few showers are possible in the Big Bend region of Texas and along parts of the Rio Grande throughout the day. Afternoon highs will stay in the low 70s for much of West Texas. But afternoon highs from Tulsa to San Antonio and points eastward will top out in the low to mid-80s.
High pressure will keep the weather nice and quiet across all of the Central Plains today. Expect plenty of sunshine today from Iowa and Nebraska south into Kansas and Missouri. It’ll be cool out this morning with lows in the 40s in most spots. Highs this afternoon will be comfortable ranging from the 70s in Nebraska and Kansas to the 60s east in Iowa and Missouri.
Cloud cover will linger behind a low pressure system in the east this morning. We could even see a few early showers in Ohio, Indiana, and Michigan. High pressure building in from the west will gradually clear skies into the afternoon. Under clear skies in the north, lows will start the day off in the 30s and low 40s. Cloud cover in the south and east will keep temperatures in the 40s and low 50s. Sunshine will warm highs in the west to the 50s and 60s, versus 40s and 50s in the east.
The Dakotas are likely to stay clear and dry today, but a trof of low pressure building in from the west will bring rain and snow to Montana and Wyoming. A Winter Weather Advisory is in effect for parts of western Montana until 5 am Wednesday. Upwards of two inches of slushy wet snow are possible in spots above 6000 feet. Lows will drop into the 30s, 40s, and 50s. The rain and snow will limit highs in the west to the 40s and 50s. Sunshine across the region will bump highs into the 60s and 70s.
A couple of upper level system will bring areas of showers and storms across Utah, Colorado, and New Mexico today with Arizona staying generally dry. Temperatures this morning will range from the 40s in Albuquerque and Denver to the 50s in Salt Lake City to the 60s in Phoenix and Tucson. It’ll be comfortable this afternoon with highs in the 60s/70s north in Utah and Colorado and 70s/80s south in New Mexico and Arizona.
High surf is possible along the southwestern California coast, with a High Surf Advisory into Wednesday. Lingering cloud cover from an upper level wave exiting the area is possible early today. Skies will clear quickly this afternoon, though. Temperatures this morning will range from the 30s and 40s in the north to the 50s and 60s in the south. Highs in northern Nevada will reach the 50s. California will see temperatures reaching the 60s and 70s. Desert areas will reach the 80s.
An upper level system will keep the weather across the Northwest unsettled today. Expect passing rain showers from Oregon and Washington east into Idaho through the day thanks to an exiting system east and another Pacific front west. Higher elevations in Idaho can expect some snow with some light accumulation possible in areas. Morning lows will range from the 40s east of the Cascades with 50s west of the Cascades to the coastline. Afternoon highs will remain cool in the 50s/60s regionwide.
