We’re looking a cool and damp weekend across the region as an overrunning weather pattern begins to set up across the area. However, forecasted rain totals from this period of rain are not expected to be very heavy. A dry weather pattern will follow next week. The biggest weather highlight next week will likely be chilly air the middle of next week that looks to bring the potential for a light freeze to much of Central Texas and the Hill Country Wednesday and Thursday mornings.
The temperature is noticeably cooler on this Friday in the wake of Thursday’s cold front. These cooler readings are expected to hold through the weekend due to widespread clouds and periods of rain. Friday’s weather maps showed a trough of low pressure located over southern Arizona that is slowly tracking to the east. Winds in advance of the trough are producing a large area of overrunning clouds that cover the western half of the state. These clouds look to expand across the rest of the state Friday afternoon and Friday night. As moisture levels increase Friday afternoon, there will be a slight chance for a spotty light rain showers across West Texas and the Hill Country. Most other locations should remain dry. Light rain is forecast to become more widespread across the western half of the state Friday night as the overrunning pattern strengthens with the approach of the upper trough. This area of rain is forecast to spread east to cover most of Central Texas after midnight Friday night.
Saturday through Saturday night, forecasts call for a cloudy sky with periods of widespread, mostly light rain showers. The approaching upper trough is expected to enhance the overrunning cloudy/showery pattern across the entire region. Little or no thunderstorm activity is forecast.
On Sunday, clouds and widespread overrunning light rain is forecast to continue through Sunday morning. The chance for rain is predicted to end from west to east Sunday afternoon as the upper trough lifts up to the northeast, ending the overrunning pattern. In fact, parts of the Hill Country could see a partly cloudy sky develop Sunday afternoon. Partly cloudy and dry weather is forecast Sunday night.
Rainfall forecasts for the weekend have trended down a bit after taking into account less Gulf moisture than what was previously thought available. Totals through Sunday are forecast to generally average between 0.25 and 0.5 inches.
