The sun offers little warmth today, but it should at least help in the coming days, especially as winds back off. We get a little bit warmer tomorrow and Thursday along with a chance of a few snow showers Wednesday night.
Then we are confronted with our first winter storm of the season starting Friday. While confidence in the winter storm forecast continues to build, slight changes can bring huge differences in outcomes. At this time, it appears that a significant to perhaps severe winter storm will impact us and forecasts should be monitored as we track this storm closely over the coming days.
Programming note: We will have new updates on the winter storm by later this morning or midday.
Today (Tuesday): A very cold start this morning with single digits in the outer suburbs to teens in the city along with wind chills making it feel like the single digits or just below zero when you’re getting out there for the morning commute. Like yesterday, plenty of sunshine is anticipated, but temperatures only manage to reach the middle to upper 20s to near 30 by the afternoon. And those winds don’t die down. Look for 10-20 mph winds from the northwest with higher gusts at times through the day. Confidence: High
Tonight: Mostly clear, still quite cold, but at least the winds fade away slowly overnight. Lows range from 10 degrees in the outer suburbs to near 20 right in the city. Winds dip down toward just 5-10 mph breezes mainly from the northwest. Confidence: High
Tomorrow (Wednesday): As cold Arctic high pressure drifts away, we get a few more clouds to offer up a partly cloudy day. Temperatures finally move above freezing to the middle to upper 30s. Winds shift to come from the southwest during the day at just 5-10 mph. Confidence: High
Tomorrow night: Partly to mostly cloudy skies with a slight chance of snow showers overnight as a weak disturbance drifts through the region. No accumulations are expected as the system looks moisture-starved. Lows drop into the upper teens to middle 20s around the area. Confidence: Medium
A LOOK AHEAD
Thursday is our “calm before the storm” day as temperatures reach their warmest levels of the week under partly to mostly sunny skies. Highs should reach the upper 30s to low 40s at least, but a few spots could manage to reach the middle 40s. Thursday night delivers mostly cloudy skies with lows in the upper teens to middle 20s around the area. Confidence: Medium-high
Friday and Saturday will likely bring the first big winter storm of the season, which has the chance to become among the biggest in years in some areas. Precipitation is likely to begin Friday morning and continue through Saturday. Snow is likely and could mix with sleet or rain at times, especially along and east of I-95. Friday night into Saturday, increasing winds could trigger blowing and drifting snow and power outages are possible. Snow accumulations of at least a few inches are likely, and double digit totals are a rising possibility, especially west and north of the city. Confidence: Low-medium
Sunday finally sees sunshine returning by especially afternoon as temperatures warm to the upper 30s and low 40s to start the melting process. Confidence: Medium
