The Winter Storm Watch in effect for all of southeast Texas, including Galveston County, has been upgraded to a Winter Storm Warning. Some uncertainty remains on exactly what we will see tomorrow due to a somewhat drier outlook overall. Still, the chances for freezing rain, sleet and snow remain.
The culprit in this latest onslaught of wintry weather is an Arctic cold front, combined with a potent upper-level disturbance now migrating eastward across Baja California. With cold air at the surface, an overrunning pattern will develop over southeast Texas with upper-level moisture flowing across the region.
This should result in light sprinkles later tonight, followed by light freezing rain, sleet and possibly snow during the day tomorrow. As noted above, the big question is how much precipitation will occur. Currently, light icing is possible with no significant accumulations (except for a band of snow north and east of a Houston-Beaumont-Lake Charles line). Forecasting these situations can be tricky, however, so some element of surprise cannot be ruled out completely.
At any rate, many vounty schools and some public facilities will be closed Tuesday. Depending on conditions, it might be wise to postpone any unnecessary travel then as well. The good news is that milder conditions should return fairly quickly to the area.
