2/15/21 9AM South Mississippi glazing update

Things continue to ramp up this morning. Rain is falling across most of the area, it is mixed with sleet across some of the western counties, and to the north (but still south of I-20, freezing rain has started to glaze over roads and bridges.

That is a look at the line between freezing things and non-freezing things as of 8:30am. To the west things are starting to freeze and to the east things are still (barely) liquid.

The Bottom Line

Not much has changed here.

Be prepared for the potential for wintry precipitation, followed by some pretty cold air. Travel will be difficult Monday before noon. Places will be impassable by Monday afternoon – especially north. And, for some places, it will be almost impossible to drive anywhere overnight Monday and into Tuesday morning.

The good news is that by Tuesday afternoon, things will start to melt and temperatures will be above freezing – barely. And you may be able to get some places. Folks in rurl areas and along county roads that are well shaded will likely still be stuck.

The bad news is that anything that doesn’t evaporate, will likely re-freeze overnight Tuesday and into Wednesday morning. That means another game of “be somewhere by Tuesday at sundown that you are comfortable being until Wednesday at noon.”

But by Wednesday afternoon, we will be back above freezing for a while. And life will get back to normal.
