More clouds will start to fill in for tonight, as a slight chance for some sprinkles mixing over to flurries pushes through. Some patchy freezing fog could develop in spots by daybreak as temperatures bottom out in the upper teens and 20s.
A mix of sun and clouds will be the case throughout the day on Sunday as temperatures max out in the upper 30s northeast, with low to mid 40s elsewhere. It will feel slightly cooler than that as a southwest wind becomes sustained at 5 to 15 mph by the afternoon.
The cloud cover will increase Sunday evening into the overnight hours as the next cold front sweeps through. That will bring along the chance of some light rain transitioning over to some snow as temperatures bottom out in the upper 20s and lower 30s by daybreak. Most spots will be dry by the time you head out the door on Monday morning, aside from maybe a stray flurry or two. Either way, little to no accumulating snow is expected out of this.
Behind that front, a mostly clear sky will return for the second half of Monday, but winds will be howling out of the north. The warmest part of Monday will be during the morning with temperatures in the 30s. Temperatures will drop throughout the day, and will get back down into the teens and 20s by the time the sun sets.
However, that’s before you factor in the wind. North winds will be gusting upwards of 30 to 40 mph for Monday afternoon, plummeting wind chills down into the single digits and close to zero by the end of the day.
Winds won’t be nearly as strong for Tuesday, but still breezy at times with a 10 to 15 mph northwest wind. That will keep wind chills in the teens and 20s for most during the afternoon, but could get as cold as the single digits for some northeastern areas.
The brunt of the arctic cold blast moves in for Wednesday and Thursday morning. Morning air temperatures both days will be in the single digits and a few degrees below zero, but wind chills could get as cold as -10° to -15° below. The best chance of seeing wind chills that low will be for the northeastern areas as that area will be the closest to the cold center. (Wind chills will be even colder to the northeast in Wisconsin and Minnesota, and around the Great Lakes region.)
The further southwest you are, the warmer it will be. Even so, it will be cold with wind chills around zero, and a few degrees below that, for those spots, as well.
Actual air temperatures only max out in the teens for Wednesday, with more low 20s sneaking in for Thursday.
Some warmer weather looks to make it’s return for Friday and next weekend as temperatures get back into the 30s and 40s.
