Clouds will quickly spread from west to east this afternoon with precipitation following as well. For parts of NW MS (Greenwood, Greenville, Grenada--Along The Hwy 82 Corridor) most of those area's will start as snow with gusty winds. As you transition from NW to SE across the state there will be snow then rain...and it will take time for the central ms area's to change from rain to snow. This a quick moving but powerful winter storm system that will bring a 6 hour window for most places to see falling precipitation. This event isn't like our previous winter weather storms---as there will be rain or snow or rain changing to snow--with no worries of freezing rain. Temps will fall quickly as the clouds and precipitation shield pushes east and the day goes on.
Currently the forecast is: Snow should change over around the rush hour for Central MS (5-6 PM). The farther North and West you go from Jackson the higher the totals will be. It's possible for the Delta to see a solid 3-5 inches, with the Central MS area to see 1-2+ inches. Farther South and East it will take the longest for the rain to change to snow, so there will be the chance for the more rain to be on the ground when the snow starts. It will take those area's longer to see any accumulating snow to occur, so those area's might see along/north of Hwy 84 a dusting to maybe at best a 1" of snow accumulation. As you travel from NW to SE across MS the snowfall accumulation totals will be dramatically different and there will be a sharp gradient from large accumulations to none. As the temps will be fall to freezing and below overnight with many locations falling into the low-mid 20's....what falls earlier in the day/evening might have the chance to freeze up on the roadways some overnight and cause hazardous driving conditions early Thursday AM. Elevated surfaces, bridges, overpasses, etc will be the primary concerned.
Currently most of NW/Central MS is under a Winter Storm Warning. You may click on the following link to scroll to find your county/town for the specifics of totals/timing/impacts of this winter storm: Winter Storm Warning Details For Your County/City

Thursday and Friday will be cold, blustery, below average temp days with snow pack of large amounts directly to our northwest and a strong front changing our winds out of the northwest blowing over the cold snow will make temps for those two days VERY chilly. However, by the weekend a warm-up starts and by the start of next week a lot of the MS area will see daytime High's in the 60's and Low's in the 40's.
