In my opinion, the bigger story this week are the cold overnight temperatures, but I do realize many of us have to plan for possible hazardous road conditions during Thursday's precipitation.
What precipitation will fall on Thursday?
This morning my thoughts are being better defined around the trending model pattern. Two days ago we definitely knew temps would warm significantly above freezing on Wednesday, but Thursday was still difficult to where the rain/snow line would exist as precipitation moves through.
Now I am getting a better feeling about the positioning of the rain/snow line Thursday morning and into the afternoon. Snow is likely in North Mississippi (Greenwood/Batesville/Tupelo/Starkville) and wintry mix/snow is expected along the I-20 corridor through Jackson and Meridian. Hattiesburg is more in the rain region because I believe the rain/snow line will make it down to Jasper County and fade into Covington, Jones, and Wayne Counties. Light snow should be seen North of Forrest/Lamar counties. Once again, Hattiesburg area should be more concerned with rain and the very cold temperatures Thursday night through Saturday.
The timing on the precipitation for the whole area will be between the morning to early afternoon on Thursday. The temperature will be dropping quickly Thursday afternoon as the cold front passes through, but, fortunately/unfortunately, the precipitation will not be around during the coldest part of the day from late afternoon into the night.
At this point, the only school systems that should be considering closing Thursday encompass the Simpson, Smith, Jasper, Clarke Counties.
