.SHORT TERM...
(Today and Tonight)

Fall weather arrives...

A beautiful fall day for region in the wake of the frontal passage.
The cold front will exit the Northwest Hill Country just after
daybreak. Winds will be from the north to northeast today between
10-15 mph, with a few isolated gusts of 20 mph during the morning
hours. A surface high pressure system over the panhandle, will
quickly move southeast across West Central Texas during the
afternoon. Much of the region will see plenty of sunshine today.
Temperatures will be pleasant with most areas seeing highs
in the low 70s.

The high pressure system will settle over the Northwest Hill
Country, along the I-10 corridor this evening. Strong radiational
cooling will be possible near the area of high pressure. In these
areas, clear skies and calm winds will allow temperatures to drop
quickly after sunset. The cold spots will be in the sheltered
valleys along I-10 from Mason to Ozona. Current forecast has these
spots 5 to 7 degrees colder than the rest of the area. Expect
overnight lows along the I-10 corridor to be in the upper 30s to
low 40s. Across the rest of the area overnight lows will be in the
mid to upper 40s.

.LONG TERM...
(Monday through next weekend)

Temperatures will rebound on Monday as light south winds return
to the area, with sunny skies and afternoon highs in the lower
80s. The warmer temperatures will be short lived though, as a
reinforcing cold front drops south across the area late Monday
afternoon and evening. The front will usher in a cooler airmass
for Tuesday, with highs in the lower 70s. Clear skies, light
winds and a dry airmass will promote ideal radiational cooling
Tuesday night, with overnight lows in the lower and middle 40s.

A rapid warmup will take place on Thursday ahead of a strong
cold front that is expected to affect the area Thursday night.
Temperatures will be above normal on Thursday, with afternoon
highs in the mid and upper 80s. Aforementioned front is expected
to bring the coolest airmass of the fall season so far for West
Central Texas, with highs in the 60s Friday through Sunday and
lows dropping into the upper 30s to around 40 degrees both Friday
and Saturday night. There is also the potential for some light
rain behind the front Friday night but due to some model
differences with the upper pattern during this time frame,
will only include 20 POPs for now.
