Most sites are VFR early this morning, except KSOA which is LIFR.
Given the patchy nature of the fog/stratus, TEMPOs were included at
some of the sites, with generally VFR conditions prevailing. All
sites will become VFR by late morning/early afternoon as a cold
front moves through the region. Expect north winds of 12 to 18
knots, with higher gusts, then decreasing this evening.
.PREV DISCUSSION... /ISSUED 400 AM CST Sun Feb 1 2015/
The upper level trough that brought much needed rainfall to West
Central Texas yesterday will continue to move east of the area
this morning. Slight chance PoPs were continued across the
Northwest Hill Country for any lingering showers this morning, but
most precipitation should be south and east of the area by mid
morning. Areas of dense fog have developed across the Northwest
Hill Country early this morning. Additional areas of fog may
develop across West Central Texas this morning, especially in
areas that have cleared. We have opted to not issue a fog advisory
at this time, but an advisory may eventually be needed if the fog
becomes more widespread than currently anticipated.
As the trough exits the area, a cold front will move through West
Central Texas this morning, resulting in north winds of 10 to 15
mph and cooler temperatures. Skies will clear by late
morning/early afternoon, with highs ranging from near 50 across
the Big Country, to the low to mid 60s across the Interstate 10
corridor. Fairly good radiational cooling conditions are expected
Monday morning, with overnight lows dropping into the mid 20s to
(Monday through next Saturday)
Mainly dry through the next week, with temperatures generally
near normal with a couple of exceptions.
On Monday, we will be cooler than normal behind the cold front
moving through today, but dry, and winds will be turning from the
northeast to the south by the evening hours as sfc lee troughing
to our northwest develops.
As the upper level low currently over northwestern Mexico
approaches and eventually moves across South Texas Tuesday night,
it will bring a chance for mainly showers to the southern 1/3 of
the forecast area Tuesday afternoon into Tuesday night. The cloud
cover associated with the system should result in slightly cooler
temperatures across the I-10 corridor compared with the rest of
the forecast area, so have highs in the 50s for southern areas
Tuesday while the rest of the CWA is in the 60s.
As the upper level low moves by our area to the south on
Wednesday, the entire area will warm into the 60s. Another cold
front will move through the area Wednesday night, resulting in
another brief cool down for Thursday. Friday into Saturday, an
upper level ridge will strengthen over the southwestern U. S., and
spread into Texas, resulting in warming temperatures and dry
conditions. Highs will warm into the upper 60s to near 70 degrees
across the area by Saturday.
