From Brian Germ:
Scattered showers and storms will be around Central Texas Saturday evening as plenty of moisture remains in place. Most of the activity will diminish after sunset from the first batch of storms out of the south. Showers and storms will increase from the west and northwest Saturday night and into Sunday morning as a cold front approaches. Most of the rainfall should only affect areas west of I-35, with a 40% chance of showers expected. Temperatures will fall into the lower and middle 70s.
Clouds and moisture will be on the increase throughout the day on Sunday as the front slowly drifts across Central Texas. Rain and storm chances will be highest by the late afternoon and evening hours. Rain and storm chances are around 70%. Winds will be out of the southeast during the morning hours, but then switch around out of the north as the front moves through during Sunday evening. Highs Sunday afternoon will be warm out ahead of the front, with temperatures reaching the middle and upper 80s. Cooler air is expected behind the front by Sunday evening and into Monday.
Showers will be around parts of Central Texas Monday morning but then begin to dissipate in coverage by the afternoon and evening hours. Rainfall totals around the region by Monday evening will total from 1 to 3 inches, with higher amounts favoring our western counties. Highs Monday will be noticeably cooler, with temperatures staying in the 70s!
Fall-like conditions will stick around for the first part of the work week with highs staying in the upper 70s and lower 80s. A few showers may be possible Tuesday afternoon, but rain chances will be very slim as most areas just enjoy the cooler conditions. Low temperatures by next week will be in the upper 50s and lower 60s! Temperatures slowly increase by the end of the work week with a ridge of high pressure back in place. Highs will return to the middle and upper 80s, but drier air will be in place keeping the humidity values low.
