1/15 – Payton’s Monday Afternoon Forecast

A zonal flow pattern in the upper levels and a retreating surface high will allow temperatures to modify into the middle to upper 50s today. Skies should remain clear as a very dry airmass lingers over the Gulf South. Tonight will be a period of transition as another strong Alberta clipper system dives through the northern Plains and into the Midwest. As this system moves into the Midwest, a strong cold front will sweep through the central Plains and into the Lower Mississippi Valley. An increase in mid and high levels clouds can be expected late tonight as the front approaches, and temperatures will be several degrees warmer as mid-level winds turn southwesterly. Low temperatures should cool into the 30s and lower 40s.

The strong arctic cold front will progress across the forecast area through the day tomorrow, as temperatures should begin to cool in the afternoon and evening hours. Fortunately, moisture will begin to dry up as the front moves into the forecast area on Tuesday, and only have a slight chance of precipitation in the forecast through the day. Most of the precipitation is expected to fall as rain, but areas in Southwest Mississippi may see a light wintry mix early Tuesday morning and again early Tuesday evening. No accumulation of ice or snow is expected. Closer to the I-12 corridor, a very brief period of changeover from rain to a light wintry mix could occur Tuesday evening for a couple of hours. Again, no accumulation is expected given the very light nature of the precipitation. A few flurries or sleet pellets is generally what is forecast for the evening hours. By late evening, any precipitation chances will push offshore, and skies will begin to clear from north to south across the area. Temperatures will cool dramatically as skies clear, and expect to see lows in the upper teens and 20s across the forecast areas. Breezy conditions should push wind chills into the single digits and teens, and a wind chill advisory will likely be issued for Tuesday night and Wednesday morning.
