What winter weather to expect through Fri. 2/4/11

Hello everyone -
The National Weather Service has issued a Winter Storm Warning for southeast Texas effective from noon today through noon Friday.

The warning means that dangerous winter weather like ice is expected.

I think the timing of the worst of the weather will be from 9 pm tonight through 6 am Friday. Problem is that even if the precpitation stops at 6 am, there will be a lot of icey roads. So, I wouldn't be surprised if there are lots and lots of school and even business cancellations. Conditions should be vastly improved by Friday afternoon.

Snow is possible (several inches), especially for area north of the 59 corridor. But the biggest concern is ice. The 1000-500 mb thicknesses south of the 59 corridor may not ever be low enough for snow production. But, the low level temperatures will be below freezing for a good portion of the area. And, that means that if cold rain falls, it has a good chance of turning into ice, especially for exposed bridges and overpasses.

Be safe everyone!
