KPRC forecasters said showers were already falling in the western counties of their coverage area, with pockets of steady rain possible through Thursday evening. They advised people trick-or-treating Friday evening to bring rain gear.
Rain from Tropical Storm Vance is expected to move into Texas through Saturday. Forecasters said rain on Friday and Saturday depends on whether the tropical moisture meets a lifting mechanism, such as a small low-pressure disturbance. They said the rain could miss the area if the timing is off. Halloween's forecast high is 84 degrees, which the station said puts it near one of the warmest Halloweens on record. The station noted a high of 88 degrees in 2004.
