A low pressure trough to the west, southwest winds aloft, abundant moisture and a slow-moving cold front may bring excessive amounts of rainfall to parts of Texas, with up to 7 inches possible in some areas.
While precipitation is likely in Galveston County from late today through Thursday, it appears as though the heaviest amounts will be to the north of our area, where the most favorable upper-level conditions will be and where a slow-moving cold front is most likely to linger.
As wet as the winter has seemed, it may surprise some to learn that rainfall amounts in the County are generally running below normal since January 1st. This is because, although we have had an abundance of cloudy, damp days, most of the precipitation so far this year has been relatively light. However, this latest bout will bring an inch or more to the County, even if the focus of the precipitation will be off to the north and northeast of our area.
Looking further ahead, we will keep a chance of rain in our picture through the weekend, with a cold front bringing another shot at heavier rain by Sunday or Monday. This may not be all bad, since early to mid-spring can bring dry conditions to areas near the coast and many residents are in the process of restoring their freeze-damaged vegetation.
