Sunday produced widespread, heavy rain across the Houston area, with generally 1 to 5 inches. Accumulations were greatest near Galveston, and just to the southeast of the Houston area. Some of the storms were quite ominous, such as the clouds depicted in this photo from the Galveston-Port Bolivar Ferry System. Others, such as a large system that moved through downtown during the afternoon hours, produced a lot of lightning.
The conditions that produced these storms, particularly a moist atmosphere and slow-moving upper-level low pressure system will remain in place today, so we can expect another wet day before we begin transitioning to drier weather later in the week.
Today
As the upper-level system slowly moves from west to east across the region, we’ll see another wet day—especially later this morning and into the afternoon hours as daytime temperatures move into the mid- to upper-80s. Some regions could see another 1 to 3 inches, with greater localized amounts, especially to the east-southeast of Houston, from Galveston to Baytown. Given the already wet soils, we’ll have to be more concerned about the potential for flash flooding today. We’ll keep an eye on things.
