Area Forecast Discussion National Weather Service Austin/San Antonio TX 251 PM CST Thu Jan 20 2022

SHORT TERM (Tonight through Friday Night).

Cold temperatures are in place across south central Texas, with the latest surface observations showing the freezing line in place from central Val Verde county to far northwest Bexar county to central Williamson county. Along and north of this line, temperatures are as low as the mid 20 across the Hill Country. Farther south, readings are in the mid 30s to lower 40s. With plenty of cloud cover and some light precipitation, temperatures likely won't move much from current readings. So far, no impacts to travel have been observed or reported.

Radar data shows mainly light echoes ongoing across most of south central Texas early this afternoon, with a few stronger echoes noted across the Hill Country. So far, precipitation has fallen mainly in the form of light sleet or light freezing rain. We did get one report of light snow up near Marble Falls earlier today. Forecast soundings show an impressive layer of dry air in place beneath the lower-level cloud layers. With light echoes falling through the dry air, most of the precipitation has been able to evaporate or sublimate before reaching the ground. However, as noted above we have seen some heavier radar echoes from time to time.

Current radar trends should gradually decrease as we head into the evening hours as hi-res models suggest most of the precipitation will continue to move to the east while weakening. With this in mind, we did opt to end the Winter Weather Advisory a little earlier for portions of the southern Edwards Plateau, Hill Country and into a small portion of the I-35 corridor. The Advisory for this region will end at 6 PM. Farther south through most of the I-35 corridor, we do expect a gradual decrease in the precipitation as the evening progresses. As long as current thinking holds, we should be able to begin removing some of our I-35 counties from the Advisory, perhaps as early as mid to late evening. For the coastal plains and along Highway 77, we will keep the Advisory intact until 6 AM Friday morning. While atmospheric moisture remains a little higher in this region, temperatures may take some time to drop below freezing. The models do continue to show an area of precipitation developing across south Texas this evening, and some of this could impact our southern counties. Cold temperatures are in store tonight with overnight lows in the teens to near 30 degrees.

Precipitation should be finished for most areas by mid-morning, with the coastal plains being the last to clear out. We should see a gradual decrease in cloud cover, but with cold air in place, afternoon highs will generally remain in the 40s. Another cold night is in store Friday night with lows in the 20s and lower 30s.

LONG TERM (Saturday through Thursday).

The primary concerns for the long term will be seasonally chilly temperatures over the upcoming weekend and some much-needed rain chances returning to the forecast Sunday night into Monday in response to a passing shortwave.

Saturday morning will be another chilly one across south-central TX with a widespread freeze across the area with sfc high pressure in place. The upper pattern will consist of a Great Lakes trough and a cutoff low centered over AZ that is forecast to remain nearly stationary until late on Sunday. Cloud cover will begin to develop during the day over western areas, both in the SW flow aloft and at the top of the boundary layer as low level moisture begins to increase. This will keep temps from rising much Saturday afternoon, and forecast highs are only near 50s west and in the low to mid 50s east. Slightly warmer in our northeastern areas on Sunday, perhaps pushing the upper 50s, but still below normal.

Shower chances increase quickly Sunday night as the closed low quickly pushes east after opening up. It will find an environment with PWATS increasing to 0.8-1.2", and showers should begin to develop around the midnight hour Monday morning, increasing in coverage and intensity during the day over primarily the east half of the area before exiting through the afternoon and evening. Model depictions take on a textbook baroclinic leaf look by midday Monday. At this time there is moderate to high confidence that this system will not be able to wrap in enough cold air for any frozen precipitation types, as the next push of polar air looks to hold off until Tuesday. Rainfall amounts of 0.25-0.5" are a good bet for many areas except for the southern Edwards Plateau, with isolated higher amounts possibly exceeding 1" mainly along and east of I-35.

As dry air quickly moves in behind the sfc trough, the clouds will clear and if that happens early enough, temperatures will rise significantly over our western counties Monday afternoon. Forecast highs are well into the 60s there, although east of I-35 with the rain and clouds we don't expect to reach 60 again until Tuesday if at all. Forecast confidence is low beyond that but we will likely remain in this cool regime for at least a couple more days next week.

PREV DISCUSSION. /ISSUED 139 PM CST Thu Jan 20 2022/

UPDATE . We have made some changes to the Winter Weather Advisory. The duration has been shortened to 6 PM today for the southern Edwards Plateau, Hill Country and into a small portion of the I-35 corridor. More information will be included in the afternoon forecast discussion.

Also, please see the 18Z aviation forecast discussion below.

AVIATION . Some upper end MVFR cigs will continue along the I-35 corridor as some light wintry precipitation tries to make it to the surface through the dry air in the low-levels. Will continue to monitor radar trends this afternoon but have only mentioned a TEMPO group for the I-35 sites for a few more hours this afternoon. With the depth of dry air increasing in the low-levels overnight into Friday morning, we do expect VFR cigs through the remainder of the forecast period. Gusty north winds continue this afternoon, then gradually decrease overnight into Friday.
