Area Forecast Discussion National Weather Service Austin/San Antonio TX 340 AM CST Sun Jan 16 2022

SHORT TERM (Today through Monday). After a hectic wind day Saturday, elevated winds on the backside of the strong upper low have decoupled to leave a more downsloping offset to the cold air advection pattern at the surface early this morning. So while very low dew point temperatures and lighter winds over West Central TX and the NW Hill Country is dropping temps into the mid 20s, most of South Central TX will see relatively mild cooling relative to the strength of the Saturday morning front. Some of the metro areas will remain above freezing through the morning, but outlying areas and more protected locations may see some 29-32 degree temps.

The cold air advection pattern isn't over yet for late this morning, and after the sun mixes some of the winds at around 4000 feet down over Central TX the result will be a west to east temperature gradient to where the western counties will lose the CAA trend early. By this afternoon, the winds will shift in direction will spread to our eastern counties, breaking the CAA and bringing a slightly more rapid warm-up with west to southwest winds. In the evening this wind direction will not provide as much influence on the temperature trend, being that speeds should be less than 10 mph, and the very dry dew points will take over for rapid cooling tonight. So while this morning the NW counties should see the coldest temps from this pattern, Monday morning should see NE counties with the colder temps. Some of the higher terrain areas such as Rocksprings could see a warmer min temperature trend by as much as 6 degrees. A secondary high pressure surge is forecast to move into N Texas tonight, but models came into good alignment on showing this feature dissolve over Central TX, leaving a near calm wind on the east side of the Austin metro area. A broad zonal flow pattern over TX reinforces the increase of S/SW winds for Monday and hastens the warming trend to above normal maxes after starting off the day with below normal min temps. Very few clouds are anticipated through the short-term periods.

LONG TERM (Monday Night through Saturday). A dry and stable westerly flow aloft combined with south to southwesterly winds in the low-levels will yield above normal temperatures across the region on Tuesday. The next cold front set to impact the region should move through Wednesday afternoon. The initial surge of air behind the front looks to be more of a Pacific origin and with plenty of sunshine and downslope west to northwesterly winds in the low-levels, most areas will see temperatures at or above what we expect on Tuesday. The exception will be across a fairly small portion of the Hill Country where some colder air is set to arrive by late afternoon. Much cooler overnight lows in the lower 30s to lower 40s and windy conditions are in store behind the cold front Wednesday night. Breezy north winds, cloudy skies and below normal high temperatures are in store across all areas on Thursday, with highs in the lower 40s to lower 50s. We will keep a low chance for showers in the forecast on Thursday into Thursday night as a warm air advection pattern develops in advance of a disturbance moving southward out of the southern Rockies. There is some disagreement noted among the medium range models with regard to the upper air features and precipitation chances (and type) as we head into late this week. The operational GFS is showing higher precipitation chances while the operational ECMWF and Canadian models are trending much drier. For now, we will keep precipitation chances fairly low as confidence in the models is not high that far out in the forecast period. We can't rule out some wintry precipitation late Thursday into Friday, but confidence is low and we will not mention in the forecast at this time.

It does look like cooler than normal conditions will persist through the end of this week, especially Friday as cold air advection and clouds keep highs down in the 40s to near 50 degrees.
