Area Forecast Discussion National Weather Service Austin/San Antonio TX 321 AM CST Sun Jan 26 2020
SHORT TERM (Today through Monday). Widespread fog across South Central Texas with Dense Fog Advisory in effect until 9AM. Dry air begins to filter in this morning and clouds will clear from northwest to southeast behind a weak cold front. Temperatures still above normal today with highs in the mid 70s with mostly clear skies. Overnight lows will be in the mid to upper 40s with the drier air in place. Northwest winds switch back to southeasterly by Monday morning and moisture recovers. Mondays highs will again be in the 70s for most of the area with fair skies and light winds.
LONG TERM (Monday Night through Saturday). An upper level shortwave trough will move quickly through South Central Texas late Monday night through Tuesday morning. Dynamical forcing appears good with this system, with time height progs showing strong mid-level vertical ascent atop a relatively shallow stable layer. We are anticipating a complex of elevated showers and embedded thunderstorms to develop across the southwestern Edwards Plateau and Rio Grande after midnight and move east into the I-35 corridor shortly before sunrise on Tuesday morning. This is indicated by most global models as well as the 3KM NAM12 and 3KM Texas Tech WRF that now go out through this time frame. While instability parameters aren't great, the amount of forcing, combined with sufficient deep layer shear, could result in a stronger storm or two capable of producing small hail.
The system is forecast to quickly move east of the I-35 corridor by midday Tuesday with drier air filtering into the area from west to east behind a cold front. Windy conditions behind the front are forecast to develop down the Rio Grande, and combined with the drier air could result in a period of elevated fire weather conditions Tuesday afternoon across this region.
Cooler and dry conditions are forecast for Wednesday. Another upper level system is currently indicated by global models to dig further south than the previous system. Wednesday night an upper level low is indicated the be digging into northwest Mexico, west of the Big Bend. There are some differences between the ECMWF and GFS on how and where the energy ejects northeast into Texas and how it phases into a digging northern stream trough Thursday and Friday. Therefore PoPs are capped at less than 50% during this time. Next weekend appears dry and warm.
Climate. A freeze is not forecast through the remainder of January at San Antonio, Austin Camp Mabry, or Del Rio. Assuming a freeze does not occur through the end of the month this will be the first time since 1939 that San Antonio has not had a freeze in the month of January, since 1950 at Del Rio, and since 2006 at Austin Camp Mabry.
Here are the years where it did not freeze in the month of January for our climate sites:

I do not sell or share any user data or anything else for that matter.

I use this to block hackers and other bad actors. I do not use this raw data to create profiles on users. I periodically delete the log files. If you are subject to CCPA, Google ads on this site will not be based on your past behavior so you will likely not see an ad for a lawn mower just because you looked for one at a big box website. I do not believe this site is subject to CCPA but I am doing what I can to follow the guidelines anyway.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerous of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
