Temperatures Slowly Rising as Precipitation Ends

Posted on: 9:52 am, February 2, 2013, by

Temperatures are climbing to the lower 30s behind the heavier precipitation this morning, and that’s a good thing. Roads will continue to be slippery (especially bridges) until we climb to around 33-35º F in an hour or so.

A Winter Weather Advisory remains in effect; the worst of the snow & ice is now east of I-65 through Lincoln, Madison, Jackson, DeKalb, Franklin (TN), Marion (TN), Grundy, Bedford, and Coffee Counties. Up to 2 inches of snow have fallen in Franklin County, Tennessee, and a solid inch covers most of Lincoln County. Here are some specific reports:

*Dusting in Harvest
*1.2″ of snow in Cowan, Tenn.
*2.0″ of snow near Sewanee, Tenn.
*Dusting near Scottsboro
*Icy overpasses in Huntsville/Madison
*O’Neal Bridge and Wilson Dam slick earlier this morning

This has been a little bit of a surprise since precipitation is about 3 hours ahead of schedule. We expected the best chance of wintry mix to be north of us due to the timing, but since it came in earlier, temperatures were colder at the onset of the rain/snow/sleet. That’s why you woke up to the surprise this morning! In fact, this is the kind of thing we expected to happen about a week ago (Friday, Jan. 25) when all of those schools delayed and we got nothing but rain. These minor systems are very, very tricky!

Here’s what to expect for the rest of the morning:

The heavier mix is already tapering off west of US 431, but Sand Mountain, Lookout Mountain, and the ridges along the Cumberland Plateau will still see about an hour’s worth of icy conditions in Jackson, DeKalb and Marshall Counties. Franklin (TN), Marion (TN) northeast toward Grundy, Coffee, Sequatchie and Hamilton Counties will get the worst road conditions since temperatures there are in the middle 20s.

The sun is already peeking out behind the heavier precip, and that will help us warm above freezing and make travel conditions “good” again between 10 AM and Noon west of US 431; Jackson, DeKalb, Marshall, Lincoln, Franklin (TN), Marion (TN), Grundy, Coffee, Beford, Sequatchie and Hamilton Counties will see icy roads through early afternoon. Be careful as you venture out; sidewalks, patios, and driveways are often quick to ice over as well.

Temperatures will rise into the 40s west of I-65 just after lunch; expect a high near 40 degrees in the higher elevations of Northeast Alabama and Southern Tennessee by early afternoon. Road conditions will improve northeast of Huntsville between 1 and 3 PM.
