Warmer temperatures began this weekend for the East Coast and will continue through much of this week and really through much of the remainder of February as several ridges of high pressure build over the region the next several weeks. Now this week, the overall theme will be for above average temperatures, but there will still be a day or two where there will actually be a cool touch to the air due to brief intrusions of cooler, polar air from Canada.




On Sunday, the Central U.S. will be on the cool side as a cold high pressure moves in while the East Coast stays warm due to a strong flow of warm, southerly air. High temperatures in the Northeast will range from the 20s and 30s in northern New England, where snow and freezing rain will fall, to the 40s and 50s in southern New England and the remainder of the Northeast, and to the 60s and even the 70s in the Mid-Atlantic region. To the south, it will be toasty in the Southeast with widespread high temperatures into 70s and 80s for most locations. South Florida will be especially mild with some locations nearing 90 degrees.

Then on Monday to begin the new week, high pressure will allow for drier weather in the Northeast but also cooler temperatures. It will be a very seasonable day for the region with highs generally in the 30s and 40s, although it will be cold near the Canadian border and back into the Great Lakes region with temperatures only maxing out into the 20s. Meanwhile in the Southeast, temperatures will remain up to 20 degrees above normal translating to actual temperatures in the 60s, 70s, and 80s. It will be cooler due to a frontal passage in the Tennessee Valley and west of the Mississippi River, however, where highs will be in the 40s and 50s instead.




On Tuesday, temperatures up and down the East Coast will generally be between 5 degrees below average to 5 degrees above average. Highs in the Northeast will be in the teens, 20s, and 30s with the colder temperatures begin found the farther north you are. To the south, the warmer air will be in the Gulf Coast states with high temperatures in 70s. Cold air damming in the Carolinas through north Georgia will keep temperatures on the cooler side into the 40s, 50s, and 60s.

As the axis of the ridge of high pressure moves from the southwest Atlantic to the Gulf of Mexico, that will allow for highly anomalous temperatures to return for the latter half of the week. On Wednesday, the entire Eastern U.S. will experience temperatures between 10 and 25 degrees above normal, making it feel more like early-spring instead of mid-Febraury. Across the Northeast, many locations will top off into the 40s or 50s but it will be even warmer in the Mid-Atlantic with highs for some locations into the 60s, maybe even in Washington, D.C.. It will be even warmer in the Southeast, although about the same compared to average. Widespread high temperatures in the 60s and 70s is forecast.




Thursday and Friday will likely be the warmest days of the week as warm air is maximized ahead of a approaching cold front from the Central US. High temperature will be as much as 40 degrees above average for most locations. Portions of the Northeast will likely experience highs in the 60s while in the Southeast, widespread highs into the 70s is expected. Here’s a sneak peak at the forecast high temperatures for Thursday:
