Weekend Weather Outlook
November kicks off its first weekend with extreme weather of almost all kinds, dabbling in flooding, blanketing snow, and even severe storms to shake off the relative calm that October arranged.
Today
A warm front will lift across the nation’s midsection for the start of the weekend. Rain showers and thunderstorms will be widespread across the Plains and Mississippi Valley. The best chance for any showers and thunderstorms will occur in the afternoon and evening. Given plenty of instability and fierce winds aloft, there will be a chance for severe weather, mainly over the central and southern High Plains. The main concerns within thunderstorms would be destructive winds and large hail, but an isolated tornado or two cannot be ruled out.
At the same time, an upper-level weather system and associated cold front will be advancing through the West. Precipitation will spread northwest-to-southeast throughout the day, making it to the Rockies and Southwest by later in the day. Coastal areas and lower elevations should just see rain today. Cold temperatures will allow for wet snow or mixed showers in the mountains and higher elevations.
A large area of high pressure will be settled over the eastern U.S. Dry weather will be in the forecast as a result. Though, a few showers are possible across the Florida Peninsula northward into the Appalachian North Carolina.
High temperatures will be in the 40s and 50s across the Northwest, Great Basin, and Rockies as well as the northern Plains, Great Lakes, and Northeast. However, the mercury will struggle to get out of the 20s and 20s for the higher elevations. Sixties and 70s will be widespread across California and the Desert Southwest along with the central and southern Plains, Midwest, Mid-Atlantic, Deep South, and Southeast. A few isolated 80s are possible for far southern areas.
Sunday
On Sunday, before the first full workweek of November enters the scene, storms and showers alike will continue to relieve many states left in an intense October drought.
A low pressure system in the Great Plains seeks to further organize itself as it launches northeastward through Sunday, surging scattered thunderstorm conditions and widespread showers across the Great Plains, Midwest, and even the Great Lakes. Anywhere west of the Mississippi River and north of the Ohio River through New York has a good chance to see at least light showers.
Ingredients conducive to multiple rounds severe storms will exist in the south-central Plains on Sunday, holding heightened strength in the afternoon hours. Threats of high winds, large hail, and even isolated tornadoes are not out of the question amidst supercells and severe storms lines here. These same storms will be trotting over already saturated soil, dumping inundating rainfall totals that will result in flash flooding for some locales in the southern Plains. Remember, “Turn Around, Don’t Drown!”
Additionally, a separate low pressure system is primed to inch eastward across a vast majority of the West on Sunday outside of parts of Nevada. Blankets of snow will line most peaks in the Rockies and Cascades, with over a dozen inches of snow expected on the peaks of the Colorado Front Range. Primarily, a few inches are expected through most high elevations locales, save for more along the tallest mountains of the West, with mixed precipitation shaking up the mid-elevations. Some isolated showers are possible along portions of the Pacific Coast.
Withholding isolated showers in the Southeast and New York, the High Plains and Eastern U.S. will remain rain-free as higher pressures sneak around the lows. At their highest on Sunday, high temperatures into the 90s will arise in South Texas. Lower 70s to upper 80s keep warmth present through the Desert Southwest, Deep South, south-central Plains, Florida, and Lower Mississippi Valley.
Middling highs in the mid-50s and 60s will mark thermometers in the Southeast, Mid-Atlantic, Appalachia, central Plains, Pacific Southwest, and the rest of the Lower Midwest, while 40s and lower 50s chill the Northeast, far northern Plains, and middle elevations across the West. Of course, peaks along the Rockies and Cascades will steak the coldest highs on Sunday, only reaching 30s at most and 20s at minimum.
