WINTER STORM WATCH now in effect until Tuesday 12:00 AM for Grenada and Carroll (MS) counties. Freezing rain looks to begin sometime mid morning Monday through the Monday evening.
–A relatively strong cold front currently situated west of the viewing area will result in very heavy rain and plummeting temperatures later this afternoon/evening.
Rain amounts exceeding 4.00″ fell in parts of western Tennessee due to this system and temperatures there abruptly dropped 10 degrees.
We can expect this heavy bulk of rain to move into our western counties later this afternoon and eastern counties early this evening. Flash flood watch/warning already in effect for much of the viewing area.
With the ground already completely saturated from previous rain events, even more rain will result in flooding in many locations. Our models have projected anywhere between 1-3 inches of rain by the end of this event.
Falling temperatures will result in a very cold rain this evening. Temperatures which are currently in the 70s will fall into the 50s shortly after the front moves through. Light rain mixed with light freezing rain could occur overnight. But, greatest threat for freezing rain looks to be during the afternoon Monday through Monday night in mainly our Northwestern counties. Elsewhere, surface temperatures are extremely warm and ground is also highly saturated, so freezing concerns will remain limited to overpasses and bridges through Monday evening.
