AVIATION. /06Z TAFS/ Surface dewpoints are slowly warming and should approach saturation toward daybreak. VFR skies should exist at all TAF sites through around 09Z, and then there is a chance for patchy dense fog after 09Z. Will stick to the notion that the shallow moisture return will hold off until daylight for the I-35 terminals; by this time surface winds are expected to increase to above 5 knots to lead to prevailing IFR conditions in the late morning. Continued increases in onshore winds should solidify the low cloud deck for much of the day with VFR conditions not expected to return until late afternoon. Meanwhile, only diurnal wind shifts warrant extra lines in the DRT TAF. The onset of low clouds and possible fog for early Monday morning should be a fewer hours earlier than from tonight.
PREV DISCUSSION. /ISSUED 211 PM CST Sat Dec 7 2019/
SHORT TERM (Tonight through Sunday Night) . Upper air analysis this morning showed a low amplitude ridge over West Texas with west-northwesterly flow over the region. At the surface, high pressure was centered over us and winds were generally light and variable. Temperatures were five to 10 degrees lower than 24 hours ago. The upper level ridge will flatten during this period. The surface high will move to the east and low level winds will become southeasterly to southerly. This will lead to a dry, warming pattern. We will start to see deeper moisture return tonight as the flow becomes more southerly and there will be some patchy fog over the Coastal Plains counties. Sunday night low cloudiness will develop across most of the CWA. Temperatures will warm through the period.
LONG TERM (Monday through Saturday) . Monday night into early Tuesday a cold front will move through our CWA. With good moisture return between tonight and the frontal passage Monday night we expect widespread rain across the region. The best chances will be during the day Tuesday behind the front. Rain chances will linger into Tuesday night as the upper trough moves across Texas. Cooler, drier air will move in behind this system with below normal temperatures for Wednesday and Thursday. The end of the period will have warming trend.

I do not sell or share any user data or anything else for that matter. I do not keep site logs longer than I need to to keep bad actors off the site. Basically, I delete them after looking at them. 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.
The information on this web site has not been checked for accuracy. It is for entertainment purposes only and should be independently verified before using for any other reason. 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.
