... Wintry precipitation expected late Monday and Monday night...
Wintry precipitation is forecast to develop over southeast
Missouri by Monday afternoon... and then spread east of the
Mississippi River into southern Illinois and far west Kentucky
toward the end of the day Monday... into Monday evening. The
activity should reach southwest Indiana and the pennyrile region
of west Kentucky later Monday evening.
Mainly snow is expected north of Route 13 in southern Illinois and
across southwest Indiana with some sleet possible. Snow... sleet
and a chance of rain is forecast over portions of west Kentucky
and into southeast Missouri toward the bootheel. Over the
remainder of the region... mainly snow and sleet are anticipated.
1 to perhaps 2 inches of snow mixed with some sleet... is forecast
over portions of southeast Missouri... southern Illinois and
southwest Indiana. Amounts around 1 inch will be possible over
west Kentucky. Totals may be lower toward the Tennessee border
should more sleet and rain factor in Monday night. As the
precipitation ends from west to east Monday night into early
Tuesday... it should transition to mainly light drizzle... or
flurries. Patchy freezing drizzle cannot be ruled out in areas
that dip just below 32 degrees by Tuesday morning.
Given the complexity of the forecast with respect to precipitation
type... forecast amounts may be subject to change. Should colder
air hold across the region... snow totals may have to be adjusted
upward slightly. Should warmer air move farther north than
expected from the Tennessee Valley... then wintry precipitation
totals will likely be lower. Temperatures not far from 32 degrees
will also play a role in accumulation efficiency. So stay tuned
for later statements and possible advisories... as the concern
still exists for travel impacts across the region late Monday and
especially Monday night.
