1/16 – Payton’s Tuesday Afternoon Forecast

Today through this evening will be the main focus of the short term discussion. A strong arctic cold front is currently pushing across northern Louisiana into NW Mississippi, and will move through the forecast area during the morning hours. Before this front moves in, a surge of warmer air has started to advect in from the west. This has resulting in rising temperatures early this morning, and now expect to see temperatures around daybreak in the upper 30s and lower 40s at most locations. As a result, the initial precipitation that moves will be in the form of rain.

By late morning and early afternoon, a transition over to light sleet and snow should NW of our viewing area in SW Mississippi ans SE Louisiana. Precip amounts will be very light as moisture divergence is still expected to occur over Southeast Louisiana today. Currently forecasting not much more than a dusting of snow across Southwest Mississippi and the Florida Parishes of Southeast Louisiana by this evening. Below the I-10 corridor, a transition from light rain to light sleet and snow should occur in the late afternoon or early evening hours. Again, any precipitation will be very light, and little to no accumulation is expected. However, the risk of some black ice forming on a few bridges has prompted the extension of the WINTER WEATHER ADVISORY.

Temperatures will quickly drop in the afternoon and evening hours, and still expect to see lows middle to upper teens north of I-12 and the lower to middle 20s elsewhere. A HARD FREEZE and FREEZE WARNING remain in effect for the region. Additionally, strong north winds of 15 to 20 mph combined with the cold temperatures will push wind chills into the single digits and teens late tonight and tomorrow morning. A WIND CHILL ADVISORY also remains in effect for the area due to these bone chilling temperatures.

Although temps tomorrow will climb into the 40s…Wind chills will make it feel like the 20s throughout the day. Winds should finally begin to decrease tomorrow night as a surface high settles over the region, and clear skies and low humidity values will allow temperatures to fall back into the upper teens and lower 20s north of I-10 corridor, and the middle to upper 20s closer to the Mississippi coast.
