Summer cancel in the East – After warmer weather brought an extended summer to the East Coast, cold air will dominate this week’s temperatures.
Nor’easter? – New England could get hit by a blast of rain and winter weather during the second half of the week as a coastal storm moves up the East Coast.
Hot in the West – A ridge of high pressure will sit over the Southwest U.S. this week, bringing much above normal temperatures to most of the West Coast, the Rockies and the Northern Plains.
Deep Freeze in the Southeast – Much of the Southeast will see lows in the 30s, with some areas going below freezing Friday and through the weekend.
“Cold” will be the word of the week along the East Coast as prolonged below normal temperatures break the hot streak that began way back in March. November is forecast to be slightly below normal in a lot of major cities in the East, which would be a first for most since the early spring. Aiding these cooler temperatures is a developing low pressure system, which will meander across the Southeast tomorrow and Wednesday. The upper-level trough associated with this system will allow a pocket of energy to dive down through the Midwest and develop a coastal storm during the second half of the work week. This system has some Nor’easter potential, and could definitely bring some snow and rain to New England.
Behind this coastal system, cool air will pool into the Mid-Atlantic and Southeast. The Deep Freeze is likely to take place in these areas, with lows dropping into the 30s. Sub-freezing lows could reach into central Alabama and Georgia Friday through Sunday as clear skies and calm winds allow for massive radiational cooling.
While the East turns into an icebox, the West will go the opposite direction and warm up to much above normal levels this week (+8 to +15 F). Sunny skies and downsloping winds under a ridge will keep things relatively toasty from Cali all the way up to Central Canada as the cold tries to undercut the ridge in the Southern Plains.
Models are indicating that a progressive pattern will set up once again across the U.S… perhaps it’s time again to call for some powerful systems to roll through the country in weeks 2-3 of November. Our severe weather outbreaks are not done!
