November Arctic outbreak, already cold month (Details).
A powerful arctic cold front early next week will deliver the coldest air of the season to the central, southern and eastern U.S., shattering dozens of mid-November records in the process.
Of course it has already turned sharply colder over much of the Midwest, South and East from what has been a parade of arctic cold plunges, pushed south from Canada by a southward plunging jet stream.
The coldest spots in the northern Rockies, Northern Plains and upper Midwest dipped below zero earlier in the week. A few locations in northern Montana plunged to the teens below zero Thursday morning.
Rochester, Minnesota, dipped to 0 degrees Friday morning, the fourth earliest date in the season it had done so.
Record daily lows were tied Saturday morning New York’s JFK Airport (25 degrees) and Worcester, Massachusetts (15 degrees) and set in Trenton, New Jersey (19 degrees) and Baltimore (24 degrees).
Next Week’s Colder Blast
If that wasn’t enough, another blast of cold air will sweep into the central and eastern U.S. early next week, the coldest air of the season for many.
This next front will plunge quickly through the Northern Plains and upper Midwest Sunday, into the Southern Plains and Ohio Valley Monday, then through the East Coast and Deep South Tuesday.
By Monday, highs in the teens may be widespread in the Northern Plains, and temperatures may struggle to rise out of the 20s for highs as far south as the mid-Mississippi Valley and Central Plains. These are daytime highs more typical of January than November.
Monday’s high temperatures could be the coldest on record for Nov. 11 in dozens of cities in the Midwest and Plains. This includes Minneapolis and Chicago, where the coldest high temperatures on record for that date are 19 degrees and 28 degrees, respectively.
Tuesday’s highs may be the coldest on record for Nov. 12 over a widespread area from the interior Northeast and Great Lakes into the Ohio Valley and lower Mississippi Valley. Highs may be stuck below freezing as far south as Tennessee and in the 40s as far south as the northern Gulf Coast, including Houston and New Orleans.
