Our long-awaited winter weather system no longer looks as strong as it did a day or two ago.
But that doesn’t mean it will be easy going Thursday.
As the cold front moves in after midnight, a rapid temperature drop will cause flash freezing of surfaces, creating some slick spots.
This system has steadily diminished its potential for significant accumulation over the past 36 hours. That means we are now looking at a widespread 0.5″ to 1.0″ total, with a few spots possibly as high as 1.5″.
Then there’s the wind.
Gusts will reach as high as 40 mph from the northwest as the front barrels through, both overnight and during the daytime Thursday. This will result in areas blowing snow and reduced visibility, especially in rural/open locations. Please travel with care.
Thursday’s high will be 13, with that temperature likely being seen in the morning, and slowly falling temperatures the rest of the day. With sustained wind speeds of around 25-30 miles per hour and those higher gusts to 40, wind chills will be below zero all day.
A second weak system arrives Friday with a chance of light snow in the later part of the day.
After that, expect dry and cold conditions through next Wednesday. Highs will be below freezing each day, with lows in the single digits above and below zero.
