Administrators NorthGeorgiaWX Posted January 16 Administrators Share Posted January 16 MD 0072 CONCERNING WINTER MIXED PRECIPITATION FOR SOUTHERN MS INTO CENTRAL/SOUTHERN AL AND A SMALL PART OF NORTHWEST GA Mesoscale Discussion 0072 NWS Storm Prediction Center Norman OK 0232 AM CST Tue Jan 16 2024 Areas affected...Southern MS into central/southern AL and a small part of northwest GA Concerning...Winter mixed precipitation Valid 160832Z - 161330Z SUMMARY...Winter precipitation will shift eastward early this morning. Embedded heavier showers of sleet or freezing rain will be possible. DISCUSSION...Early this morning, a broad area of post-frontal precipitation is ongoing from southern MS into central AL. This area of precipitation will continue to spread eastward this morning in conjunction with the front and a weak eastward-moving frontal wave across the northeast Gulf of Mexico. Weak but nonzero MUCAPE (as noted in the 06Z BMX sounding) will continue to support fast-moving showers with briefly moderate precip rates embedded in the broader light precipitation shield. A substantial warm nose aloft (also noted on the 06Z BMX sounding) atop a shallow subfreezing layer at the surface will continue to support freezing rain and sleet as the primary winter precipitation types. Strong low-level cold advection will continue to push the surface freezing line southeastward with time, with a transition to freezing rain expected into parts of south-central AL, southern MS, and northwest GA, where temperatures are currently above 32F. Deepening cold air beneath the warm nose will support primarily sleet across the northwest portion of the precipitation shield. Some oscillation between freezing rain and sleet is possible within the transition zone. ..Dean.. 01/16/2024 ...Please see www.spc.noaa.gov for graphic product...
