Weather Roundup: National Forecast for Oct. 2
A raw, nasty day in New England on Wednesday gives way to gradually clearing skies in the Northeast on Thursday. Rain from the Connecticut River Valley over towards Cape Cod should mostly clear by noon, with clouds and a few residual showers clearing by rush hour. Everybody else should be dry with high temperatures mostly in the 60s. But, our big weather maker comes later on in the week in the form of a strong cold front which pushes through the region starting late on Friday and into Saturday and Sunday, bringing a blast of showers and storms before temperatures plummet to below average levels to start next week.
A strong cold front moves in late on Thursday night for extreme western Kentucky and Tennessee, but most everyone will be dry for Thursday. But Friday, our cold front will mean a chance of stronger showers and storms from Nashville to Charlotte, and some of those storms could be severe. Temperatures behind the front will cool quickly to well below seasonable levels, with most areas in the 50s and 60s by the weekend.
The persistent rains in Florida finally come to an end by the weekend once a strong cold front moves through by Saturday. That front will move through Mississippi and western Alabama on Thursday, Alabama, Georgia, and the panhandle of Florida for Friday and South Carolina and much of Florida on Saturday, bringing a chance of stronger storms. It’ll lead to significantly cooler weather by the end of the week, with 70s and even some 60s for highs by the start of the weekend.
Morning lows will be nice in cool for most of the Texas and Oklahoma Panhandles as temperatures dip in to the low to mid-50s. By contrast, the rest of the South will in the upper 60s and low 70s in the morning hours. Expect scattered showers in the morning for parts of northeast Oklahoma. The cold front will keep much of western Texas and Oklahoma cool with highs topping out in the low to upper 70s. But further east, highs will be in the upper 80s and lower 90s for most locations in the South. Expect rain in parts of Oklahoma and Arkansas, some storms that develop could be severe.
Showers and storms likely across the Central Plains for today as a storm system continues to impact the region as it makes its way east. Most of the activity will be across Iowa and Missouri for the second half of the day. Strong to severe storms are likely this afternoon and evening especially over Missouri and Eastern Kansas. Lows this morning will be in the 50s/60s east and south with a 40s/50s expected throughout Nebraska. Temperatures will top out in the 60s/70s around the region this afternoon with the exception of Missouri where highs will be in the 70s/80s.
A low pressure system moving through will continue to bring showers and thunderstorms across the region. Some storms could become severe in Illinois and western Indiana this afternoon. Heavy rainfall will also be a threat with this system. A second cold front will quickly follow behind, bringing in much cooler air by the end of the week. This morning, lows will mainly be in the 50s and 60, with a few 40s in northern Minnesota. High temperatures will range from the 60s in the north to the 80s in the south.
A Winter Weather Advisory is in effect until noon today for Browning, Marias Pass, and Logan Pass in Montana. A cold front building in from the north will bring a chance of rain and snow showers across Montana this morning, moving into the Dakotas this afternoon. Wyoming has a good chance of staying dry. It will be a chilly morning with lows in the 30s and 40s. Afternoon highs will be lucky to reach the 40s and 50s in the west. The east will have a better chance at 50s and 60s.
The weather is looking nice and quiet for the Four Corners today with dry conditions and mostly sunny skies regionwide. Expect morning temperatures in the 30s/40s from Flagstaff and Albuquerque northward into Colorado and Utah. Areas farther south will start the day off in the 50s/60s. Afternoon highs will range from the 60s/70s over the lower elevations of Utah, Colorado, and New Mexico to the 90s over Southwest Arizona.
The forecast will bring two extremes to the region today. A Freeze Warning is in effect for northeast California and western Nevada until 9 am. Lows there will be in the 20s and 30s. Everywhere else will see morning temperatures from the 40s to the 60s. On the flip side, a Heat Advisory is in effect for much of the California coast into Friday and Saturday. Expect highs into the 90s and 100s in those locations. Highs elsewhere will range from the 60s in northern Nevada to the 80s in the desert. Parts of southern California (just north of Los Angeles) have a Red Flag Warning with the hot, dry air increasing the fire threat.
High pressure will be in control across the Northwest today with a mix of clouds and sun expected anywhere from Idaho west into Oregon and Washington. Temperatures will start today in the 30s/40s regionwide. Most spots will top out in the 60s/70s this afternoon with a few 50s over Eastern Idaho.
