A wet and cool weather pattern is forecast to develop this coming weekend into next Monday as the trough of low pressure over the southwestern US slowly moves to the east. The trough is forecast to move across Texas this weekend, exiting to the northeast sometime on Monday. The approaching trough is expected to cause the development of widespread overrunning rain showers Saturday that will likely continue Sunday into Monday. The rain should taper off next Monday. The latest rainfall forecasts call for 3-day totals of around 1-1.5 inches across the Hill Country and Central Texas regions. Totals of 2-3 inches are forecast across the coastal plains region. NWS rainfall forecast for the period from 6 am Saturday through 6 am Monday:
Temperatures are forecast to stay quite chilly due to the widespread clouds and rain. High temperatures Saturday through Monday are forecast to be in the low and mid-50s. Low temperatures will be in the upper 30s across the Hill Country, the low 40s across Central Texas and the upper 40s across the coastal plains.
Looking ahead to next week, the large trough of low pressure is forecast to exit northeast on Monday. A dry weather pattern is forecast for most of the week. However, temperatures look to stay somewhat cool with highs in the 60s and lows in the 40s. There are some strong hints that even colder air will spread south into the region sometime late next week.Tropical Weather Update
