FIRST ALERT WEATHER: First Alert Day for wintry weather tonight & Monday morning

Good Sunday evening, everyone. We turned much colder today with temperatures plunging from the 40s by midnight to the 20s for much of the day. Under cloudy skies, we have also seen some periods of mist, drizzle and freezing drizzle in parts of the Ozarks. Now that we’re seeing another disturbance in the upper levels come into play, winter weather advisories are in place until Monday morning.

With this disturbance and an additional boost of low-level lift and moisture, this will keep periods of light freezing drizzle, light freezing rain and light sleet in the forecast for the Ozarks through tonight and into early Monday morning. By the time we hit sunrise, the activity should wind down to mainly light freezing drizzle and a little light snow.

By the time this disturbance winds down Monday morning, any expected accumulations will be very minor. We’re anticipating ice amounts under a tenth of an inch and any potential sleet & snow accumulations to stay under half an inch (closer to a quarter of an inch). While this won’t bring any power lines down, this will cause bridges, overpasses and untreated roads to become a bit slick for the Monday morning commute. Plan on taking extra time and taking it slow if you’ll be on the road Monday morning.

There may be a few isolated slick spots for the Monday morning commute.

The workweek is looking a bit more active with several chances for some winter weather. However, the impacts look minor. The cold and breeze conditions continue for Monday, highs topping out in the upper 20s to low 30s under cloudy skies. An upper level disturbance moving through Monday afternoon and evening with a shot at a wintry mix of precipitation. This disturbance will be fighting some dry air in the mid levels, and I think some people will remain dry. Those that get enough moisture will likely see some light snow mixing with sleet. I don’t think there will be much accumulation with this next round. Even though temperatures remain below freezing, the wintry mix is looking very light.

A similar story for Tuesday, temperatures below freezing under a mostly cloudy sky. In the mid to late afternoon, another round of a wintry mix arrives, with a bulk of the precip remaining south of I-44. Accumulation potential for Tuesday is a little higher, but I still think it’ll remain light. At best, a dusting on some grassy surfaces. Guess what? Another chance at a wintry mix arrives Wednesday too! This time, it’s looking like more rain than sleet or snow. If temperatures trend a little colder, I think this would be our best shot at some higher snow accumulation totals. Moisture profiles are looking much better by midweek, however, it’s looking just a little too warm. We’ll monitor this in case anything changes.

By the end of the workweek, warmer temperatures return. We’ll be in the 40s Thursday through Saturday, with the 50s in sight for Sunday.
