Tonight and Tomorrow...

At the risk of sounding like a record on repeat, quiet conditions will occur across central Mississippi as model guidance continues to show a 1025 sfc high slowly shifting east out of our forecast area.
Similar to yesterday, northerly flow aloft will continue to suppress any build up of moisture. Sky conditions will be generally clear across central Mississippi heading into the overnight hours allowing for radiational cooling to take affect. Because of this, nighttime temperatures will cool into the low to mid 40s. By early Wednesday morning, returning low-level moisture from the Gulf may bring a chance of fog and low clouds mainly south of I-20. Tomorrow, conditions will remain fairly quiet across our CWA as clouds start to build from the west. Around this time, mid-level ridging will be over the region. In addition to this, surface ridging will be centered over the eastern CONUS. This will allowing for moisture flow to build across the southeast US. The combination of ridging surface and aloft will help afternoon highs peak in the low 70s.

Wednesday Night through Tuesday...

The forecast for the extended period remains the same with some slight adjustments made to the wind gusts for Thursday. By Wednesday night, model guidance hints at a sfc low across the Central Plains moving east as the sfc ridge shifts east out of central MS. Heading into Thursday, a low pressure system across the Central Plains will shift east towards the Ohio River Valley. Above this sfc low, a shortwave trough that will swing east towards central Mississippi.
This will introduce the possibility of rain for the period with the highest chance being centered over northern MS. In addition to the rain, global guidance is showing strong sfc winds up to 20-25 mph with gusts up to 30-40 mph across the area on Thursday. Given the increased dynamics, went ahead and blended towards higher MOS guidance. Made a slight adjustment to the timing of the graphic in order to capture the early morning gusts. Otherwise, kept the limited wind graphic the same across the area for much of Thursday.

By Friday afternoon, the shortwave trough will push out of the area as the sfc low shifts northeast towards the Upper East Coast.
Heading into the weekend, high pressure will move into the area from the west which will end all rain chances and keep weather conditions quiet heading into the next work week. /CR/

AVIATION
(18Z TAFS)
Issued at 1155 AM CST Tue Feb 20 2024

VFR conditions with light southwesterly winds to begin the TAF period at all sites. An increase in moisture overnight with returning southerly flow from the Gulf of Mexico will bring chances for IFR conditions due to low stratus and fog development to mainly the TAF sites south of Interstate 20. /NF/
