Quiet weather lasts into Tuesday ahead of cold and snow

Remaining Ad Time Ad - 00:00

ROCKFORD (WREX) — We will be on a bit of a roller coaster late this week, thanks to snow showers and very cold air. Until that point, Tuesday keeps quiet weather around for one more day.

High pressure is overhead, keeping the weather quiet and dry through Wednesday afternoon. Temperatures remain near average under the high. Tuesday's high temperature reaches the low 30's.

Breezy winds kick in by Tuesday afternoon, providing wind chills in the teens. While temperatures barely change, Tuesday will feel colder than Monday due to the stronger winds. Tuesday starts out cloudy, then turns sunny by the afternoon.

Weather models show snow starting up by Wednesday evening.

Wednesday looks quiet up until the evening. Snow showers kick in by early evening, and could impact the drive home. Snow continues to fall throughout Wednesday night, and wraps up sometime Thursday morning. For now, a couple inches look likely. The brunt of the storm is to our southeast, so snow totals look to ramp up as you move southward.

Plenty may still change as the forecast storm track comes more into focus. For now, plan on a couple inches or more for snowfall, and slippery roads by Thursday morning.

Extra cold air from the Arctic floods the Stateline by Thursday.

Very cold air slides in Thursday behind the departing storm. This air is coming in from the Arctic, so temperatures drop throughout Thursday. We'll start out the day near the 20's, then drop into the single digits by Thursday evening. Thursday night is likely below zero, which would be the first time we see subzero temperatures all winter (which is pretty late). Wind chills approach -20° that night.

Valentine's Day looks frigid with highs in the low teens. Wind chills likely remain near or below zero all day. We will see a sunny sky, at the very least. By the weekend, warmer weather near 40° is possible. This does come with a chance for rain and snow, especially by Sunday.
