The wedge, or cold air damming event, will break through this Wednesday, allowing for a surge of warmer temperatures across the East. On Wednesday, widespread temperatures of 5 to 15 degrees above average is forecast east of the Mississippi River. Meanwhile to the west, a cold, Canadian high pressure will begin to drop down into the Northern Plains. That will keep high temperatures only in the 20s and 30s across most of North Dakota and northwestern Minnesota, which is up to 25 degrees below average.

Then on Thursday, the cold air will expand while the area of above average temperatures in the East shrinks. Highs are still expected to generally be 5 to 15 degrees above average across the Northeast, Southeast, and Gulf Coast, but the Mid-Atlantic will be particular toasty with highs 20 to 30 degrees above normal. That translates to actual highs in the 70s and 80s. Back toward the Central US, most locations will deal with temperatures 5 to 15 degrees below average.

Following a brief blast of cooler air into the Central and Southern Plains, the cold air will become more confined to the Northern Tier on Friday. Below average temperatures of as much as 30 degrees is expected from Montana through the Dakotas and into all of the Midwest. In the Midwest, it will definitely be cooler than average, but it will be more like 2 to 8 degrees below normal for the general region. Meanwhile along the US East Coast, we’ll be basking in the spring warmth. Temperatures will be 5 to 10 degrees above average from New England through the Carolinas and the Florida Peninsula. This will translate to actual high temperatures ranging from the 50s and 60s in New England to the 60s, 70s, and 80s for the Mid-Atlantic and the coastal region of the Southeast.

By Saturday, cooler temperatures will invade the Northeast. The coldest of air will remain locked into Montana and the Dakotas where high temperatures will be as low as the teens near the Canadian border, which is definitely winter-like. The Upper Midwest will experience temperatures 10 to 25 degrees below normal while the Lower Midwest through the Northeast is generally 2 to 10 degrees below normal. The Southwest through the Southern Plains will remain mild with widespread temperatures of 5 to 15 degrees above average. The Gulf Coast and the Southeast will be comfortable and near-average.

On Easter Sunday, you may want the egg hunt inside if you are in the Northern Tier. Temperatures will be 10 to 25 degrees below average for a widespread region on Sunday, including the Northern and Central Plains and the Midwest. It won’t be too terrible in terms of comfort in the Northeast and Mid-Atlantic. That’s where temperatures will be less than 10 degrees below average for most locations. The Southwest, Texas, and the Gulf Coast will remain mild.
