12/11 Ryan’s “Clear & Calm” Tuesday Night Forecast
Tonight will be clear, chilly, and calm, but we’re beginning a warming trend that will take us almost back to the 70s by Thursday. The cooler and drier air that moved in behind last weekend’s front is moving eastward into the Atlantic, and we’ll see “return flow” begin as the axis of the associated ridge slides East.
THIS WIND DIRECTION CHANGE ALONE WILL ACCOUNT FOR A +20 DEGREE SWING BETWEEN TONIGHT’S LOW AND WEDNESDAY’S AS MORE WARM, MOIST AIR MOVES IN.
The atmosphere continues to get warmer and more humid into Thursday, which is when our next active weather moves into South MS. This low pressure system currently carries a “marginal” risk for severe weather, but it mostly looks like rain and localized flooding will be the main issues again. The upper level low pressure system moves in Friday, and will keep cloud cover and scattered showers in the area for one more day. Afterwards skies will clear and temperatures will fall below average for a few days as we begin next week.
