–Friday’s windy storm exits the area overnight but not before producing snow over the southern half of the metro area—heaviest in northwest Indiana where accumulations of wet, wind-driven snow threaten dicey travel conditions for the opening hours of Friday night.

–In Chicago, a wet snow/rain mix exits the area with partial clearing. (A full summary of the current storm system’s impact is covered in earlier posts).

–We’re headed into a third consecutive above-normal weekend—though lake breezes Sunday and a better-organized east/southeast flow will restrict shoreline warming Sunday.

–Skies range from partly cloudy to occasionally cloudy Saturday and Sunday.

–An eastbound low pressure brings a surge of warmer air which may include 2023’s first official 60-deg Chicago high temp Monday. But the system also introduces some rain showers to our weather picture Sunday night and Monday with chances put a 60% Sunday night and 35% Monday.

–A COLDER OVERALL WEATHER REGIME LOOMS AS PART OF A PATTERN CHANGE after Monday’s 61-deg high—a shift likely to produce below normal daytime temps from next Tuesday through the following weekend and the week which follows.

–Of interest later next week is the potential for a storm system that could generate snow or a wintry mix.

–Temps this week have averaged 8-deg ABOVE NORMAL—but with cooling after Monday’s 61-deg predicted high, next week is to come in nearly 3-deg below normal and the week which follows (March 12-18) is predicted to post a 9-deg deficit.
