(Today and Tonight)
A closed upper low will continue to move southwest away from the
area through tonight. At the surface, a weak cold front is currently
moving south across Oklahoma and will enter the far northern
counties of the Big Country by late morning and then stall around
the I-20 corridor this afternoon. Scattered showers and a few
thunderstorms will be possible today in association with the front
and also from some remaining influence of the departing upper
low. Carrying chance POPs across much of the area, except across
southwest sections where likely POPs will remain in the forecast.
Rainfall amounts will be tricky again today due to uncertainty
with the extent of convection that may develop along the front.
Convergence along the front will be weak, so organized convection
is not anticipated and precipitation amounts should be light,
generally 1/4 inch or less. A bit higher totals are expected
across southwest counties where up to 1/4 inch will be possible.
High temperatures today will generally be in the lower to middle
80s, with some upper 70s across far southwest sections where more
extensive cloud cover is expected.
Could see some lingering precipitation across southwest counties
this evening, otherwise precipitation will end. Low temperatures
tonight will be mainly in the lower 60s.
Sunny and warmer weather is expected to return Saturday and
Sunday as an upper level high pressure builds into West Central
Texas from the northwest. The warmest day should be on Sunday
with highs climbing into the lower to mid 90s. Models prog a surface
low pressure system to form in the lee of the Rockies and extend
south across North Texas on Sunday in response to strong westerly
upper level flow across the Central Rockies. The location of this surface
low should result in a dry and warmer southwesterly breeze to
flow into the region.
A fast moving shortwave trough crossing the Northern Plains will
send an associated cool front into West Central Texas by Monday
afternoon. High temperatures on Monday just prior to frontal
passage should range from the mid 80s north to the lower 90s
across the northwest Hill Country. This front is expected to
lower temperatures into the lower and mid 80s by Tuesday. For
Wednesday and Thursday, continued sunny skies with high
temperatures rising into the mid and upper 80s to near 90 as weak
upper level high pressures prevails.
