A warm end to February is definitely in the cards for much of the East, especially the Southeast. This week, daily temperature records will be broken or tied for many cities along the East Coast. Now in the Northeast, this warm up will be brief, with record warmth forecast Tuesday through Thursday morning, but in the Southeast it will be very prolonged with the intense heat lasting through at least the weekend.
On Tuesday, millions will wake up to record warm temperatures in the morning. These are called record warm minimum temperatures, so in short it means there has never been a morning that warm ever in history. This widespread record warmth will be found in the southern Great Lakes into the Ohio River Valley through the Tennessee Valley, portions of the Midwest, eastern Southern Plains, the Gulf Coast, and into Florida. Spotty records are also possible in portions of the Northeast, including New York City and Washington, D.C.. In terms of actual numbers, the highest temperatures will be located the farther south you are. In the East, these record warm low temperatures will range from the 40s in the Great Lakes region to the 70s in South Florida. As we get into the afternoon, dozens of record high temperatures will be broken, mainly up and down the US East Coast and into the Ohio Valleys and Gulf Coast states. High temperatures in the East will range from the 60s to 70s to 80s for the large majority of locations. In South Florida, a few towns may top off at 90 degrees.
On Wednesday, the story will be the same as a ridge of high pressure strengthens further, allowing for this record heat. Meanwhile back to the Central US, a cold front will continue to move south and east, therefore introducing colder air into the Midwest and Southern Plains. Therefore, all of the warm air will become confined east of the Mississippi River. Nearly 100 out of the 287 climate recording stations in the nation are forecast to experience a record warm minimum temperature Wednesday morning. That includes almost every station east of the Mississippi plus Louisiana and extreme-southeast Texas. Low temperatures in this Eastern US region will range from the 50s for most in the Northeast to the 60s in the South. As the sun rises, that sunshine will heat the air up. Most areas will feel temperatures into the 70s and 80s; A town or two in Florida will get into the low 90s again. Almost every station in the Northeast, Mid-Atlantic, and Southeast (not including Florida) will likely break their daily record high temperature. Even all-time record high temperatures for the month of February may be broken in some cities, like Boston for example. The record in Boston holds at 73 degrees, which was recored just last year, but we’re forecasting a high of 70 degrees, so there is the chance we break it but either way it will definitely be one of the warmest temperatures for the month.
Now on Thursday, a strong cold front will push through the Northeast and Mid-Atlantic but not before more record warm minimum temperatures are expected to be accomplished. From the Boston area southward through the Southeast, more of these records are expected to be broken Thursday morning. Now as temperatures maximize in the afternoon, it will only be in the 40s and 50s in the Northeast, which is still above average but not even close to record levels, whereas the Southeast will be baking. About a dozen record highs are expected to be broken in this region as actual temperatures soar back into the 70s and 80s.
For the remainder of the week, it will remain above average in the South, although only a few cities are expected to break their daily temperature records as cooler air continues to infiltrate the Northern Tier.
