Area Forecast Discussion
National Weather Service Austin/San Antonio TX
319 AM CST Sat Feb 22 2020

.SHORT TERM (Today through Sunday)...
High clouds will continue to push across South Central Texas through
the short term forecast period as an upper level low pressure system
west of California moves to the northeast into the four corners
region. Low level moisture is expected to increase as well later
this afternoon and evening as a low level jet sets up over the area
ahead of the upper level disturbance. The upper level system is
forecast to move across the Southern Plains on Sunday and sends a
Pacific front our way on Sunday night. Ahead of the frontal passage,
there is a slight chance for showers across the far east of the area
on Sunday afternoon. High temperatures over this weekend will range
from the upper 50s across the Hill Country to mid 60s across the
coastal plains and along the Rio Grande. For Sunday, expect a warmer
day with highs in the mid 60s to upper 70s along the coastal plains
and southwest part of the local area.

&&

.LONG TERM (Sunday Night through Friday)...
The southern stream upper level trough moving from the Plains into
the Midwest Sunday night into Monday will send the tail end of a
Pacific cold front through the region on Monday morning. A few
showers could be possible along and ahead of the front for areas
along and east of the Interstate 35/37 corridor. Skies will clear
behind the front by Monday afternoon and temperatures should warm
nicely into the low to mid 70s for most locations with northwesterly
winds.

Models continue to be in good agreement depicting an upper level low
and accompanying trough dropping out of Canada and into the Central
US on Tuesday, sending a stronger front through the region on Tuesday
afternoon. Cold, dry air and breezy northerly winds will come behind
the front, with low temps on Wednesday morning near freezing across
the Hill Country with upper 30s elsewhere. Wednesday will be sunny
but chilly and windy. High temperatures will be in the 50s for most
locations with breezy northerly winds.

The pressure gradient will relax by Wednesday night as high pressure
builds in over Texas. Wednesday night into Thursday morning will
feature light winds, clear skies, and a very dry air mass, all of
which will allow for efficient radiational cooling. A hard freeze is
possible for the Hill Country with freezing temperatures currently
forecast for the majority of the region.

A warming trend begins on Thursday with a return of southerly flow.
Pleasant conditions are currently forecast for Thursday and Friday,
with high temperatures back to seasonal normals by Friday.
