Rain and scattered thunderstorms are likely today. Some of the thunderstorms could produce small hail. The precipitation should transition to freezing rain across portions of North Central and Northwest Louisiana after midnight tonight. Only trace accumulations are expected, but this may still be enough to produce a very thin glaze of ice on exposed surfaces.
Freezing rain is possible across much of Northwest and Northern Louisiana and much of East Texas south of a line from Tyler to Marshall Friday morning. Temperatures should warm during the day Friday for the precipitation to transition back to all rain. However, more freezing rain and sleet is expected areawide beginning Friday night and into the daytime hours of Saturday. Accumulations should remain very light, most likely only a trace. However, this may still be enough to produce a very thin glaze of ice on exposed surfaces.
A much more significant winter storm is expected as snow moves back into areas along and north of Interstate 30 Sunday afternoon. A mix of sleet and snow, and some freezing rain, is expected farther southeast. As even colder air arrives on Monday, a gradual transition to all snow will occur. There is still a great deal of uncertainty regarding accumulations. However, snowfall accumulations of at least 3 to 6 inches are possible northwest of a line from Jacksonville TX, to Shreveport, to Farmerville LA, and 1 to 3 inches of snow and some ice accumulations are expected farther to the southeast.
Yet another round of a mix of rain and snow is expected Wednesday.
In addition, extremely cold weather is expected Friday through Wednesday. The coldest temperatures are expected Monday night and Tuesday morning as overnight lows fall into the single digits for most locations north of Interstate 20 and into the teens elsewhere.
