From Brian Germ:
Plentiful sunshine is in the forecast Sunday afternoon with highs remaining cool in the upper 60s and lower 70s. Winds will be out of the north at 10 to 20 mph.
The cooler weather will only be brief though. Warm temperatures will be on the return quickly for the start of the work week. Winds are expected to shift from the north to the south, allowing afternoon temperatures to rise into the upper 70s and 80s this week. The weather pattern for Central Texas Monday through Wednesday will be warm and mainly rain-free, with highs approaching 90° in some locations Tuesday! A few spotty showers may be possible Wednesday for eastern locations as a front nears the region. Overnight temperatures will also become warmer during the work week, with lows in the middle and upper 60s.
A stronger upper-level disturbance is expected to move into the Plains by the end of the week. Low rain chances will return to Central Texas Thursday through Saturday, and some stronger storms may be possible. Specific timing and details will be fine-tuned over the next several days as the storm system gets closer.
