Even though Spring has sprung, mother nature has other ideas. A quick moving "clipper" system brings the potential for snowflakes Thursday.
The headline for this event, like last time around, is "flurries, no worries." High temperatures Thursday should make their way into the upper 40s and perhaps lower 50s, the better part of 15 to 20 degrees above the freezing point. That is a big gap to overcome, and for most locations, will result in primarily rainfall.
Like most systems, though, timing is everything.
Showers, mostly producing rainfall, should begin in Northwest Mississippi during the late afternoon, and spread throughout North Mississippi by early evening. It is possible that the showers could be producing snowflakes even at surface level, with temperatures at the surface still in the 40s. Because the freezing point is 32°, that difference between the freezing point and the warmer air temperature all work to melt most of the precipitation over to liquid as soon as it comes in contact with the ground, if not before it even approaches the ground. Still, it would not be shocking to get reports of snowflakes as far south as US 78, but the likelihood of anything sticking is very low outside of extreme Northern Tishomingo and Alcorn Counties.
One interesting factor about this system, is the quick return of warm air. Even if moderate snow showers spread throughout the northern part of the WTVA viewing area (which remains unlikely), warm air flooding in from the south should quickly transition the precipitation over to rainfall, working to melt any snow that stuck. The precipitation should be all liquid by around midnight Thursday leading into Friday morning. The short window for snowfall, paired with the melting that's likely to occur with above freezing temperatures, travel issues should be very limited across most of Northeast Mississippi. Arkansas/West Tennessee could be a completely different story, with Northern Arkansas being a focal point for perhaps heavy snowfall.
Friday will be wet, with showers likely most of the day, but because temperatures will be above freezing, it will all be just rainfall.
The forecast for Saturday is continuing to evolve. At first glance, it looks like it could be a severe weather setup, especially for locations near Jackson. It is possible that the severe weather risk could spread into Northeast Mississippi, but the forecast is a little too hazy at this point. We'll have updates on the severe weather potential in the upcoming days, but have a "heads-up" that Saturday could get interesting if warm moist air pushes this far north.
