The week ahead: Another round of cold weather for mid-week

/ December 6, 2020 at 9:50 PM

Another week in December, and another round of freezing temperatures in the cards for mid-week. We’ll start the week with some showers in the area as a cold front gets through the area early Monday, followed by some lingering shower activity as a trough of low pressure hangs around behind the front. Once the low clears the area, temperatures really begin to fall off, and we’re back in the 50s on Tuesday after dipping into the mid-30s, well into “bring pets and plants in” territory. Expect another freeze Wednesday morning away from the immediate coast before temperatures rebound to near 60°. Mostly sunny skies continue Thursday and Friday as temperatures begin to moderate back around normal (mid-60s) for the second week of December. Then, a cold front approaches the area over the weekend, bringing some slight shower chances to the area Saturday and Sunday.

A seasonably cool weekend awaits

After a few more showers tonight, a cold front will swing through the area, reinforcing the cooler-than-average temperatures that have punctuated December so far (aside from today’s 70s, anyway). Clouds will scour out quickly in the morning on Saturday, yielding mostly sunny skies with highs in the low 60s as high pressure builds in from the west.

Cloudiness will begin to rebuild into the area on Sunday as a storm system gets together in the Gulf and heads toward Florida. We’ll see temperatures remain a few degrees below normal — generally around 60° — after a chilly start in the upper 30s in the metro area (cooler well inland and in more rural locations). Showers should hold off for much of Sunday, with rain chances beginning to come back into the picture after sunset as the low pressure system approaches Florida, and some overrunning precipitation develops on the northern flank.
