A cold front will dive southeastward into the Plains, ushering in cooler air in from Canada. It’s been a rather mild week with high temperatures over 30 degrees above average across parts of the Northern Tier. Warmer air will remain in place on Thursday with highs generally 10 to 25 degrees above average in the central US while the East Coast is more seasonable with highs within 5 degrees of average. In portions of the interior northeast and New England where the sun will be out, highs will be as much as 15 degrees above normal, however. This will translate to high temperatures in the 70s and 80s from the Northern and Central Plains through the East Coast. There will be some spotty locations that struggle and remain in the 60s in the Mid-Atlantic due to the rain. Back toward the Southern Plains and central Gulf Coast, it will be hot with highs in the 90s and 100s. Over a dozen locations may either tie or break their daily record high temperatures near the coast.

Changes will begin on Friday for some, specifically in the interior Northwest into North Dakota as the cold front ushers in temperatures of up to 25 degrees below normal. This will be quite the temperature turnaround as highs drop from the 70s and 80s down to the 50s and some 60s. Some locations may even max out only in the 40s. Warmer air will remain in place from the Midwest down through the Southern Plains. High temperatures will mainly be 5 to 15 degrees above average, and there will be some locations even milder than that. Actual highs in these areas will be in the 70s and 80s in the Midwest up into the 90s and 100s in the Southern Plains and Lower-Mississippi River Valley. The East Coast will be cooler than normal for the morning part, thanks to the rain. High temperatures will be up to 5 to 15 degrees below average in the Northeast.




That cold front will continue to bring cooler air farther south, working into the Upper Midwest and western Central Plains on Saturday. These areas will experience a drop in temperature by over 15 degrees in most locations, which is up to 25 degrees below average. That will make for a sharp contrast just to the east where highs will be up to 25 degrees above average in the eastern Central Plains and Mid-Mississippi River Valley. The Southern Plains through the central Gulf Coast and up through the Great Lakes will generally be around 5 degrees above average. Record high temperatures will be possible in the Lower-Mississippi River Valley with highs in the mid-90s. The Southeast will be seasonable while the cooler temperatures remain locked in across the Northeast, Mid-Atlantic, and Florida where highs will be up to 10 degrees below normal.

On Sunday, the intensity of the cold front and it cooler air on the heels of it will weaken. Cooler than average temperatures are forecast for much of the Plains, nonetheless. Areas to the east of there will be milder with highs 5 to 15 degrees above average with widespread highs in the 70s, 80s, and 90s. Florida will remain cool in the low 80s, which may actually break a couple record low maximums (record cold high temperatures).

By Monday, all of the Eastern US will be seasonable with many locations just a few degrees off from average. Warmer air will likely dominate much of next week.
