Today (Sunday): It’s as warm as it’s going to be for a while if you wake up early enough this morning, with maybe a few flakes mixing in as the rain exits to our east. But then big changes start to arrive, perhaps before you finish your morning coffee, as an Arctic front comes through. Early-morning temperatures near or past 50 quickly drop through the 40s and 30s during the mid- to late-morning under mostly cloudy skies. Meanwhile, sustained winds increase to 20 to 25 mph from the northwest late morning through afternoon, with gusts of 40 to 50 mph that could knock down tree limbs and power lines. Skies turn partly sunny by afternoon, but temperatures plummet into the 20s with wind chills in the teens and a stray flurry or snow shower possible. Confidence: Medium-High

Tonight: Wind chills dip into the single digits by around sunset, as temperatures continue to free-fall through the evening and overnight with clearing skies. We’ll see the coldest night of the season thus far, with lows down to the teens and single digits. Factoring in winds from the northwest near 20 to 25 mph with higher gusts, overnight wind chills sink to around minus-5 to minus-15. Confidence: Medium-High

Tomorrow (Martin Luther King Jr. Day): It’s a good day to do some chores around the house if you have the day off, as I can all but guarantee you won’t want to be spending much time outside. Monday will probably end up in the running for coldest day of the winter, with highs only in the upper teens to low 20s despite mostly sunny skies. Winds continue from the northwest at around 20 mph with gusts near 30 to 40 mph. Confidence: Medium-High

Tomorrow night: It’s another frigid night, but not as biting this time as winds gradually relax during the evening and overnight. We’ll have no problem dropping back down into the lower teens and single digits again under clear and starry skies, Winds are still out of the northwest, but diminishing to around 5 to 10 mph. Confidence: Medium-High


Lucky for us, this cold blast is fairly transient, with temperatures starting to moderate by Tuesday. We’re still well below normal, mind you, but much more manageable with highs in the upper 20s to mid-30s and light winds. High pressure holds on for mostly sunny morning skies, before our next approaching system sends us increasing clouds by late afternoon or evening. Skies turn mostly cloudy Tuesday night, which, along with light winds from the south, helps keep temperatures fairly steady, in the upper 20s to low 30s. Confidence: Medium

What Arctic blast? We’re back in the warm sector on Wednesday as winds turn breezy from the south, ahead of our next system approaching from the west. Skies are mostly cloudy with highs near or past 50, as rain chances return by the afternoon into evening. Confidence: Medium
