A pair of cold fronts will continue to push through the eastern half of the country Tuesday afternoon through Wednesday Morning. Bringing slightly cooler temperatures for parts of the Intermountain West and the Upper Midwest. A bit further east, the fronts are likely to fire off showers and thunderstorms — many of which will be severe in the Northeast. And calm condition prevail on the West Coast, while the Desert Southwest will be scorching hot (no surprise there). Check below for a region-by-region forecast.
Severe weather will be an issue through evening hours in the Northeast. The main threat will be hail and damaging straight-line winds, but an isolated tornado cannot be totally ruled out for parts of Upstate New York — east of Rochester and Buffalo. A severe thunderstorm watch is in effect for all of western and central New York until 8 p.m. EDT. Additional watches could be added as the afternoon and evening progress. The severe threat will begin to diminish a couple of hours after sunset, but isolated severe activity is still possible.
Overnight, temperatures will be pleasant with lows bottoming out in the lower 60s for inland areas and in the lower 70s for coastal regions. Some of the higher elevations in Upstate New York and Vermont could see lows dip into the upper 50s.
Wednesday will be mostly pleasant across the inland Northeast, as high temperatures will top out in the upper 70s for most locations. It will be much hotter for major East Coast cities from New York to Boston, highs will top out in the upper 80s to low 90s.
Much like the Northeast, severe weather will be a concern for parts of the Mid-Atlantic. Hail, destructive straight-line winds and isolated tornadoes are a concern for parts of western Pennsylvania and far northern West Virginia. Severe thunderstorm watches are in effect for most of Pennsylvania and West Virginia until 8 p.m. EDT, but — again — watches are likely to be issued further east as the storms move that direction. Things will calm down as the night progresses.
Overnight, lows will bottom out from the low 60s in western Pennsylvania to lower 70s in northern Virginia. Points further south, from Richmond to Knoxville will have lows in the low 70s.
Wednesday will be hot for some parts of the Mid-Atlantic; Richmond will top out near 100, North Carolina’s Research Triangle will see mid and upper 90s, while D.C. will get to a balmy 90 degrees. A bit further west, in the Appalachian Mountains, high temperatures will be in the low to mid-80s.
Through the rest of the evening, typical summer-like showers and thunderstorms are possible across the Southeast. A couple may pulse to severe levels, but overall most storms that develop will remain non-severe.
Overnight, lows will drop into the low to mid-70s across the region.
Wednesday, highs will mostly be in the upper 80s to lower 90s. Rain chances will also be going up as a slow-moving cold front shifts into the area. Rain chances will be on the increase through the afternoon hours.
A quiet but hot evening is on-tap for most of the South. Sunny skies pushed temperatures into the mid 90s for locations across Oklahoma, northern Texas and southwestern Arkansas. A few isolated severe thunderstorms are possible across northern Arkansas later Tuesday.
Overnight, lows will drop to the upper 60s in northwest Texas, while in parts of Louisiana and Arkansas will be in the mid-70s.
Wednesday will once more be hot as 90+ temperatures are likely area wide. Some locations like Dallas and Fort Worth could approach 100 degrees.
A quite, pleasant evening is on tap for the Central Plains.
Overnight, temps will drop into the mid 50s to the north and upper 60s to the south.
Wednesday, highs will be pleasant in the low 80s form Nebraska to Iowa. Further south, in Kansas and Missouri, it will be a bit warmer in the upper 80s and lower 90s. Rain chances look minimal and sunshine will be abundant.
Most of the severe weather has passed the Great Lakes, but a few isolated severe storms are possible in parts of eastern Ohio, but by early evening the severe threat is mostly over.
Through the overnight hours expect a few clouds but lows will bottom out in the upper 40s for the U.P. of Michigan and the Arrowhead of Minnesota. But a bit further south, lows will be in the upper 50s and lower 60s.
Highs on Wednesday will be pleasant. Expect mid-60s in northern parts of Minnesota, Wisconsin and Michigan, while low to mi-70s will be the norm further south.
Expect a nice, quiet evening for the High Plains.
Through the overnight hours expect temperatures to drop into the upper 40s — for the higher elevations — and mid-50s elsewhere.
Wednesday will be nice in the Dakotas, as highs only make it into the low to mid-80s. A bit further west, in Montana, temps will be abnormally high in the low 90s for locations like Missoula and Billings.
Monsoonal moisture over the Four Corners region could aid in the development of a few, brief showers and thunderstorms Tuesday afternoon, but overall rain chances remain low.
Overnight, lows will be in the low to 60s with a few clouds hanging around.
Wednesday, much warmer temps are on tap — especially for Colorado and New Mexico. Highs in those locations will be in the upper 80s and lower 90s. Parts of southwest southwest Arizona will skyrocket into the triple digits, but that’s the norm – for that area – for this time of year.
Hot conditions are entrenched across California and Nevada and that will continue through the evening hours.
Overnight, lows will range from the mid-50s in the Bay Area to mid-80s in Las Vegas.
Wednesday will once again be hot for the Golden and Silver states. Expect triple digits in California’s Central Valley and in Sin City, but head to the Bay Area and the LA Basin for milder temperatures.
Ending a hot day for parts of the Pacific Northwest, especially east of the Cascades.
Lows overnight will range from the upper 50s to low 60s across the region.
Highs, Wednesday, will be north of 90 east of the Cascade Mountains and in the upper 70s west of the Cascades.
