As anticipated, many many reports of snow have been received by NWS Jackson across central and west-central Mississippi. The much-awaited upper level low is now located over north-central Louisiana and is moving toward the east. Rain developed late last night across west Mississippi and transitioned into snow fairly quickly; therefore, some spots have already received upwards of 1" of snow such as Yazoo City. Rain has persisted across the GTR area for the last couple of hours, but finally transitioned into a rain/sleet/snow mix and now has transitioned to all snow with even a clap of thunder heard in the last 15 minutes.
Here's the RAP forecast sounding valid for 14z (8 AM) across the GTR area. Notice the red and green lines are side by side from the surface all the way to around 550mb. More importantly, they are side by side from -10 C to -15 C which favors snow growth/development as dendritically shaped flakes. These flakes will fall through the column that's sub-freezing and make it to the surface as snow. This suggests snow will continue for several more hours across central and eastern Mississippi as forecasted.
A side note: Some heavier bursts of snow are possible, and some traffic accidents have already occurred in and around the Jackson metro as well as in portions of Yazoo County. Some roads across the GTR may become treacherous later this morning as any slushing on the roads could complicate the morning commute.
