SHORT TERM. /Tonight through Monday Night/ Broad frontal boundary currently along I-20 across east Texas into southern Arkansas will be the focus for low clouds and patchy fog later tonight. A surface low is forecast to develop along the boundary across Texas before shifting east overnight into Monday across the ArklaTex. Height falls associated with a southeastward propagating 700mb trough across the Great Plains to aid in destablizing the atmosphere and help to promote showers and isolated thunderstorms in the vicinity of the frontal boundary overnight through daybreak Monday.
A deeper positively tilted upper-trough to further aid in thunderstorm intensification along and ahead of the front on Monday, mainly at the time of peak heating across much of north Louisiana and the lakes region of Deep East Texas. Some storms embedded within eastward propoagating convective line could become severe with locally damaging winds the main threat along with isolated tornadoes.
Conditions to improve behind the front on Monday night with winds becoming northwest and increasing to 10 mph with higher gusts. Much cooler temperatures expected behind the front with lows Tuesday morning in the mid 20s across southeast Oklahoma and in the 30s elsewhere. /05/
LONG TERM. /Tuesday through Saturday Night/
The aforementioned cold front should be through the region by Tuesday morning. Northwest winds will bring in much cooler and drier air into the region in wake of the front with morning lows in the 30s areawide and afternoon highs struggling to reach 50 degrees. By Wednesday morning, lows will fall below freezing across the entire region, with mid 20s possible north of Interstate 30. The surface high behind the previous front will move overhead Wednesday and northwest winds will diminish. Afternoon temperatures will remain just below normal, but will be slightly warmer with highs in the low to mid 50s. Mostly clear skies and calm winds will settle over the region Wednesday night into Thursday morning with the surface high overhead. This will result in temperatures falling below freezing areawide again.
The surface high will start to shift east on Thursday which will allow for southerly winds and warmer temperatures along with some low level moisture return to the area just ahead of our next potential rainmaker on Friday. A surface low and trailing cold front will move through the region during the day on Friday bringing another chance of showers and isolated thunderstorms to the region. There are some time discrepancies with the long term models on the progression of the system with the GFS moving it through by Saturday morning and the ECMWF keeping the system across the region until Sunday Morning. Decided to lean towards the GFS solution at this time with dry conditions returning to the region by Saturday afternoon and through remainder of the weekend. /20/

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.
