(Tonight through next Saturday) Issued at 1057 PM CST Sat Feb 21 2026 A 1050 mb arctic high over central Canada will gradually slide south over the next couple of days. There is high confidence for well below normal temperatures and gusty winds in the short term. Lows will drop below freezing across most of the Mid-South overnight. Arctic air will continue to blast into the region on gusty northwest winds on Sunday. Highs will only be in the 40s, but northwest winds of 15 to 20 mph with frequent gusts of 25 to 30 mph will make it feel more like the 20s and 30s. Sunday night into Monday morning will feel very cold as brisk northwest winds continue. Monday morning wind chills will drop to between 5 to 15 degrees. By Monday afternoon, a piece of this arctic high will be centered over the Mid-South, allowing for one more very cold night with lows in the upper teens and 20s by Tuesday morning. Southerly flow will return by Tuesday afternoon with gusty southwest winds, especially over the Delta. Temperatures will start to climb, with highs approaching normal levels this time of year.

The associated cold front will push through the Mid-South on Thursday with a medium to high chance of a wetting rain (50-70%). Severe chances are minimal (
