Short term (today through friday)...
another cool morning across south central Texas as temperatures range
from the upper 20s and lower 30s across The Hill Country to the 40s
across the Rio Grande and coastal plains. Some low to mid-level
clouds can be seen on satellite across the coastal plains, with mid
to high level clouds across the west associated with a shortwave
trough moving into the Texas Panhandle. These clouds will stick
around through the morning hours but should clear by Thursday
afternoon resulting in a beautiful sunny afternoon with highs around
60 degrees. Sunny and dry continues continue into Friday as surface
high pressure and northwest flow aloft result in a warm up with highs
on Friday reaching back into the mid to upper 70s across south
central Texas. With light winds and higher moisture along the coastal
plains some patchy fog will be possible Friday morning from
Floresville to Gonzales and points eastward.

Long term (friday night through wednesday)...
the dry and warm trend will continue into the weekend as Saturday
looks warm and mostly cloud free once again. A weak surface trough
will move across North Texas which will help a weak front move into
the area switching winds briefly from westerly to northerly Saturday
morning. Southerly flow at the surface quickly returns Saturday
night into Sunday as zonal flow continues aloft. The next shortwave
trough will take shape late Sunday across the western Continental U.S. And push
across the Central Plains Sunday night into Monday. This will push
another cold front through the area Sunday night and Monday morning.
Scattered showers and a few thunderstorms will be possible with the
front, mainly east of the Interstate 35 corridor. Rainfall amounts
will generally be around a tenth of an inch or less as the front
moves through. The system quickly pushes east late in the day on
Monday as colder air sets in behind the front. Tuesday's highs will
be a good 15-20 degrees cooler than those on Sunday, topping out in
the mid to upper 50s. These below normal temperatures will stick
around into the mid to late part of next week as the surface high
builds into Texas. Overnight lows Tuesday and Wednesday morning
should be below freezing across The Hill Country, with mid to upper
30s for the rest of the area.
