The Arctic invasion began last night, but the chill in the air on this Inauguration Day is nothing compared to what’s coming. A second, more bitter blast of cold air arrives tonight that holds temperatures below freezing until late in the work week - at least. This is the coldest air in more than two years. The cold air *may* partially retreat Friday just in time for the next storm system.
Today (Monday): We awaken to chilly temps - mainly in the 30-35 degree range with partly cloudy skies. Despite the passage of Sunday’s cold front, a brief interval of southerly winds ahead of the next front permits temperatures to bounce back into the 40s, and perhaps over 45 briefly. Swearing-in temps should be right around 40, with low-to-mid 40s for the inaugural parade. By late in the afternoon and towards evening, winds pick up and become more out of the west (at 10-20 mph) as the front approaches. We might (20 percent chance) see a brief rain or snow shower around that time. Confidence: Medium
Tonight: It becomes breezy and sharply colder through the course of the evening with snow flurries or a snow shower possible (30 percent chance). By 10 p.m., skies partially clear and most spots are near or below freezing. The remainder of the night, temps continue to steadily slide. Morning lows range from 16-22 (suburbs-city). That’s easily the coldest night of the year so far, especially when you factor in wind chills in the single digits and teens. Winds are from the northwest at 10-15 mph, with gusts in the 20-25 mph range. Confidence: Mediu

Tomorrow (Tuesday): Very cold and windy. Highs only manage to climb into the mid-to-upper 20s despite partly to mostly sunny skies. Winds are from the northwest at 10-20 mph, producing wind chills in the teens (and even single digits in the morning). Confidence: Medium-High
Tomorrow night: Frigid. Under clear to partly cloudy skies, lows range from 8-15 (suburbs-city). With a lingering breeze from the northwest around 10-15 mph, wind chills will be in the single digits to several degrees below zero in some of our colder suburbs. Confidence: Medium-High
We remain in the grips of the arctic airmass Wednesday through the day Thursday, with highs in the upper 20s to near freezing, and overnight lows in the teens. Skies are generally partly to mostly sunny, with some increase in clouds late Thursday. Confidence: Medium-High
Cloudy skies Thursday night and Friday as a storm system rolls into the area. With cold air in place, snow or a frozen mix of precipitation is most likely Thursday night. By Friday, snow or a wintry mix *could* transition to rain depending on the storm track. Highs are in the 30s and lows in the 20s. We will have more details on this possible winter weather scenario in the coming days. While this doesn’t appear to have the makings of a huge storm, it does have the potential to be the most meaningful of the winter (although that’s not saying much). Confidence: Low-Medium
Cold air reinforcements arrive for the weekend with highs in the upper 20s to mid-30s and lows in the teens. It’s looking partly sunny and dry at this point, but that’s not completely etched in stone so check back for refinements. Confidence: Low-Medium
