Warm & breezy Valentine’s Day, wintry mix tomorrow —
Happy Valentine’s Day!
It will be warm and breezy again today. High pressure sits just to our southeast, a low pressure is deepening to our west, and we’re sandwiched in the middle with gusty southwest winds.
Winds will gust 30-35 mph again today, especially through the first half of the day. That strong southerly flow will continue to usher in a warm air mass, highs make it into the 60’s for one more day! High 64 degrees under mostly sunny skies will be much warmer than average of 48 degrees.
By this evening winds shift to the north as a cold front comes through. That northerly wind will usher in a much colder air mass, lows drop into the 20’s tonight under partly cloudy skies.
By Friday we’ll have a set up where a shallow layer of cold air will blanket the Ozarks, but warm air will still be present to the south, overrunning the cold air and prompting a wintry mix.
A disturbance will roll along the front on Friday, expect precipitation to start after 10 AM — Morning commutes should be dry. We’ll keep precipitation through the afternoon and evening, with it exiting by 10 PM.
Precipitation type will vary — to the north temperature profiles will be cold enough for a mainly snow event. Expect 2-3″ snow from Rolla to Lake Ozarks, 1-2″ as far south as Lebanon.
Along I-44, including Springfield, temperatures will be warm enough aloft and cold enough at the surface for a wintry mix. Expect snow, sleet, and freezing rain. Snow accumulations will be less than 1″, but ice could top 0.10″, posing the threat for slick roads.
Farther south closer to the border, temperatures will be warm enough for a mostly cold rain event. An icy glaze is possible, roads will be wet with isolated slick spots.
Be cautious driving around during the Friday evening commute!
Temperatures stay cold on Saturday with highs in the 30’s and a few lingering clouds.
Another quick-hitting shot of rain/snow arrives overnight and exits by Sunday morning. Clouds and 30’s linger Sunday afternoon.
The next chance for rain/ snow will be late Tuesday into Wednesday.
