From Brian Germ:
After a very pleasant end to the weekend, temperatures Sunday night will cool off into the upper 40s and lower 50s under clear skies. The ridge of high pressure that settled into the region Sunday will shift east on Monday, allowing southerly winds to return across Central Texas. Afternoon temperatures will respond by warming up into the upper 70s and lower 80s under sunny skies. Winds will be south at 10 to 20 mph.
A dryline will form out west on Monday before moving towards Central Texas on Tuesday. Low-level moisture is expected to increase in response to a disturbance near the Four Corners region. Highs Tuesday afternoon will soar into the 80s with some lower 90s possible across our western areas! Winds will be south at 15 to 25 mph. Conditions should remain rain-free Monday and Tuesday.
A front is expected to push into Central Texas on Wednesday, bringing a low chance for rain mainly east of I-35. Temperatures will cool off a little, however highs should still be warm in the 80s both Wednesday and Thursday behind the front. The passing cold front on Wednesday will push north back across Central Texas as a warm front on Thursday. The dryline will form out west on Friday as instability and moisture increase, however rain and storm chances should still remain fairly low without a good source of life available in the atmosphere.
A stronger upper-level disturbance and front are expected to arrive in Central Texas over the weekend. Better rain and storm chances are likely with this system, as well as the potential for some severe weather. The timing and specifics are still in question for this upper-level disturbance, however details will become more certain over the next several days.
