Area Forecast Discussion National Weather Service Austin/San Antonio TX 215 PM CST Tue Jan 28 2020

SHORT TERM (Tonight through Wednesday Night). Clouds wrapping around the surface low pressure system over central Texas will continue to affect mainly the Hill Country through the evening period. As the system pushes to the east, clouds diminish to clear skies this evening. The one thing to keep in mind for the rest of this afternoon and evening is the breezy to windy conditions in place across the area, but mainly along the Rio Grande Plains where winds are ranging from 20 to 30 mph with gusts up to 45 mph. A Wind Advisory is in effect through 6 PM this afternoon for Val Verde, Kinney and Maverick counties. The winds come down this evening into Wednesday morning, however, it will remain elevated and ranging from 10 to 15 mph across the eastern two-thirds of South Central Texas with 10 mph or less along the Rio Grande.

Overnight lows will range from the upper 30s across the Hill Country to mid 40s across the coastal Plains under clear skies.

Sunny skies and dry weather conditions are expected on Wednesday with highs in the upper 50s across the Hill Country to near 70 across the southwest portion of South Central Texas.

Clouds will begin to increase as moisture returns from the east and northeast and an approaching upper level disturbance from the west nears on Wednesday night into Thursday morning. Overnight lows for this period are expected to range from mid 30s over the Hill Country to lower 40s elsewhere.

LONG TERM (Thursday through Tuesday). Shortwave trough will be digging south into the southwestern part of the state and northern Mexico Thursday. Models are beginning to converge on a solution with this next system. NAM12 is the most bullish with rainfall amounts for the Thursday evening to Friday afternoon period in the 1 to 2 inch range for most of the region. General model consensus however has most areas receiving up to 1/2 an inch with eastern counties picking up to an inch.

A cool airmass will be in place ahead of this system with isentropic ascent contributing to increasing cloud cover and rain showers ahead of the main forcing. Blended guidance is still too warm for Thursday, so went ahead and blended closer to the CONSRAW and NAM12 solution. As more models get a better handle on the airmass that will be in place on Thursday, high temperatures may need to be revised further. Isolated thunder chances is introduced to the forecast starting late Thursday night as the forcing ejects east over the state. The system continues to push east on Friday afternoon and clears out the region overnight Friday. Clear skies this weekend will pave the way for a gradual warm up of temperatures into the mid 70's for afternoon highs by the end of the weekend.

Both the GFS and ECMWF depict an upper level low digs farther south than the previous system and becoming a cut-off low near Baja California on Saturday. This system begins to progress eastward and energy ejects over the state on Monday bringing additional rain chances for the end of the period. POPs are low for Monday into early Tuesday given the uncertainty at this point.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
