Thunderstorms ended a long dry spell, bringing the heaviest 24-hour rainfall to the county since Hurricane Harvey. Overnight amounts included an official 3.41 inches at Galveston’s Scholes Field, giving that location its heaviest rain since 8.64 inches was measured Aug. 29.

Across the county, rainfall amounts ranged from 4.06 inches on the West End of Galveston and 4.04 inches in Texas City, with precipitation totals generally of 2-3 ½ inches over the East End of Galveston, west Texas City and LaMarque, and 1-2 inches from Dickinson and League City northwest to Friendswood.

The rains were the result of an influx of deep Gulf moisture and an upper-level disturbance ahead of a cold front expected to bring the chilliest weather of the season to the county from Tuesday evening into early Friday with wind gusts of 30 mph or higher near the coast and high temperatures only in the 50s.

Since the cold air should be relatively shallow, warm air overriding the chilly air at the surface and continuing upper-level disturbances could keep clouds and rain around through Thursday. As such, another inch to inch and a half of rain will be possible before sunny conditions return on late Thursday or Friday.

At any rate, the weather will be unpleasant enough that by Friday many will be dreaming of a return to the mild weather we have enjoyed since last week. On the plus side, at least the weather should be a little more typical for Christmas and the coming holiday season.
