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.
