Another week of above average temperatures is ahead for much of the Eastern United States. While rain and thunderstorms impacting much of the Mid-Atlantic and Florida on Sunday will keep temperatures significantly cooler than normal, a strong, upper-level ridge over the South will allow for much-above average temperatures from the Southern Plains through the Southeast and up through the Ohio River Valley.
High temperatures will be ten to twenty degrees above average in West Texas, the Ohio Valley, and portions of the southern Mid-Atlantic region on Sunday. All other areas that will experience the warmth will feel temperatures more in the five to ten degree above average range. That will translate to widespread high temperatures in the 90s. A few locations will top off at around 100 degrees in west Texas and maybe even in the Carolinas. A city like Atlanta will likely break their record high with a forecast of 92. A total of about 20 different cities are forecast to either tie or break their daily record high temperatures. Locations near the Canadian border will also be slightly above average with highs mainly in the 70s. Meanwhile in Florida, temperatures will only be in the low 80s, which is up to ten degrees below normal. The northern Mid-Atlantic region will be even cooler with highs up to twenty degrees below average, translating to actual highs in the 50s and 60s. Isolated locations will get into the low 70s.
On Monday, the heat will actually intensify, while the cooler pocket of air in the Northeast dissipates. Florida, however, will remain cool due to heavy rain. Temperatures will be up to twenty-five degrees above average in the western Ohio Valley and in the Upper Midwest. The remainder of the Midwest down through the Tennessee Valley and Mid-Atlantic will feel temperatures ten to twenty degrees above normal. All other areas, including the Northeast, Gulf Coast, Southern and Northern Plains, will feel temperatures up to ten degrees above average. This will translate to high temperatures in the 90s for a large area of real estate, reaching as far north as the northern Ohio Valley. Many other areas will feel temperatures in the 70s and 80s. There will be a cool pocket of below average temperatures that sneaks into the Central Plains.
As rain sneaks farther north into the Southeast, that would put a lid on the temperatures, keeping them below average and into the 80s. Meanwhile to the north and west, there will be a strip of high temperatures in the 90s spanning from the Southern Plains through the Ohio Valley and into the Mid-Atlantic, which is thirty degrees above normal. Some locations in the ArkLaTex may even hit 100 degrees. The Northeast and the Canadian border will also be quite toasty with high temperatures up to twenty degrees above average, or in the 70s and 80s for actual highs.
By Wednesday, the extreme heat relative to average will be found in the Northern Tier, specifically the Northern Plains and Upper Midwest, where highs will be fifteen to twenty-five degrees above average for this time of the year. That means actual high temperatures will be in the upper 70s to 80s. Most other areas in the Eastern US will be seasonably warm with highs up to ten degrees above average. High temperatures for a large region will be in the 80s while the 90s become more commonplace in the Southern Plains, which is occurrent for this time of the year. Severe record highs may also be broken in this region. Rain will continue to keep temperatures below normal in Florida and parts of the Southeast as well as along the eastern coast of New England.
On Thursday, temperatures nationwide will be up to ten degrees above average overall. There will be some pockets of highs up to fifteen degrees above normal in the Midwest. The only areas that will be a few degrees below average is in Florida and California. High temperatures in the 70s, 80s, and 90s will be the general theme coast-to-coast.
By Friday, a cold front will begin to work through the Northern Plains and Upper Midwest, bringing temperatures down to as much as five degrees below average. Portions of the Northeast and New England will also be a few degrees below normal. Otherwise, the remainder of the Eastern two-thirds of the nation will experience near to above average temperatures. Portions of the Central and Southern Plains and western Ohio Valley may be as much as fifteen degrees above normal.
Next weekend, the cold front will continue to track to the south and east, bringing temperatures down to below average levels for a day or two before it heats back up the following week.
