Area Forecast Discussion . UPDATED National Weather Service Austin/San Antonio TX 624 AM CST Fri Dec 6 2019

UPDATE. Please see the 12Z aviation forecast discussion below.

AVIATION. Some patchy ground fog is noted along the I-35 corridor early this morning, with some brief MVFR conditions for the next hour. We expect the fog to decrease quickly by 13Z as northwest winds increase behind a frontal passage. Gusty northwest to north winds will continue behind the front for the I-35 sites through late afternoon. Gusty conditions will then decrease between 22-23Z.

PREV DISCUSSION. /ISSUED 340 AM CST Fri Dec 6 2019/

SHORT TERM (Today through Saturday Night) . The surface cold front is making its way into the region this morning. Fog has developed once again across portions of the Coastal Plains and even creeping into the Interstate 35 corridor. Trends will be monitored and it is possible that a dense fog advisory may be necessary for at least a few counties. The front should be completely through the region by around 9 AM, turning winds to the north. It will be a bit breezy this afternoon, with sustained winds up to 15 mph. Skies should quickly clear behind the front as drier air filters into the region. Highs this afternoon will range from the mid to upper 60s across the Hill Country and Central Texas to the low to mid 70s across the Rio Grande Plains and the Coastal Plains. Winds will relax by this evening and with clear skies and dry air temperatures overnight will drop into the mid to upper 30s in the Hill Country to the low 40s elsewhere.

Saturday will feature mostly clear skies with high temps in the mid to upper 60s as winds begin to veering back toward the south. Saturday night will be warmer, with lows in the mid 40s for most locations due to increased moisture and a little bit more cloud cover.

LONG TERM (Sunday through Thursday) . Winds shift to southwesterly by Sunday, helping usher in warmer temperatures as highs return to the mid 70s. Monday will be even warmer, with highs approaching 80 degrees with increasing moisture and cloud cover out ahead of the next cold front. This cold front is expected to move into the region on Monday night and should produce some showers Monday night into Tuesday for at least a few folks across the region (albeit with fairly marginal QPF). Highs on Tuesday will range from the mid 50s to the mid 60s under mostly cloudy skies while lows on Tuesday night into Wednesday are expected to flirt with freezing across the Hill Country, with mid to upper 30s elsewhere. Some shower activity may linger into Wednesday, but confidence in this is considerably lower. However, temperatures will remain cool (highs around 60). Cool temps will hang around through Thursday, with cloud cover on the increase again and slight chances for rain as models show a progressive short wave trough coming across the Desert Southwest and into Texas on Friday morning.

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. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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 numerious 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.
