This cold front will traverse the Arklatex this evening, reaching the Lower Mississippi Valley by Monday morning. Scattered to numerous showers and thunderstorms will be ongoing along and ahead of the cold front to our northwest across the Tennessee Valley by Monday morning.
(Rest of today through Monday) Happy Easter! Hopefully you are enjoying the very warm temperatures provided by a strong, stacked high pressure system centered just off the southeast coast. Late morning temps were running 2 to 5 degrees warmer than yesterday, and the patchy clouds were thinner, allowing more direct sunshine to keep the warming going.
The combination of subsidence and calm winds from a stout high-pressure ridge opens the door for patchy fog early tomorrow morning. Otherwise, the weather will be quiet with lows mostly in the low 60s, or several degrees below normal for late April. On Monday, a storm system pivots from the Central Plains towards the Midwest while dragging a cold front across the MS Valley. Values are unlikely to read warmer thanks to thick cloud cover amidst modest upper-height falls. , Valdosta/Cross City where greater ridge influence will be.
