330 pm cdt Mon sep 16 2019
Short term (this evening through Tuesday)
issued at 328 pm cdt Mon sep 16 2019
as of 20z Monday afternoon, an expansive midlevel ridge continues to
reside across the eastern 2 3rds of the CONUS with troughing in the
west. Midlevel water vapor reveals a shortwave trough lifting
northeastward across northwestern NE resulting in scattered showers.
At the surface, a broad trough was positioned across the high plains
from eastern nm through the western dakotas. The benign weather
pattern is expected to continue through Tuesday with temperatures
remaining well-above average. Overnight lows tonight will reach the
70s with highs Tuesday afternoon in the 90s. Coupling the heat with
the high humidity will yield an another day with heat indicies in
the upper 90s.
Long term (Tuesday night through Monday)
issued at 328 pm cdt Mon sep 16 2019
transitioning into the extended period, a few thunderstorms are
possible late Tuesday night into Wednesday morning as a shortwave
trough ejects across the northern plains shunting the aforementioned
surface trough into southern NE before stalling. Another round of|
showers storms are possible late Wednesday night into Thursday
morning along the stalled frontal boundary across far northern
ks southern ne. Better chances for thunderstorm activity arrive
this weekend as the main midlevel trough ejects across the
northern plains, shunting the surface frontal boundary into the
area. Temperatures look to remain well-above average through much
of the weekend with highs in the 80s and 90s. The previously
mentioned cold front will likely result in closer-to-normal
temperatures with highs in the low 80s by Sunday.
Aviation (for the 18z tafs through 18z Tuesday afternoon)
issued at 1234 pm cdt Mon sep 16 2019
vfr conditions are expected through the TAF period. Southerly
winds will remain near 6-12 kts through 00z before decreasing
through the night and increasing after sunrise Tuesday morning to
9-15 kts. In addition, marginal llws conditions are expected
tonight as a 30-35 kt LLJ near 1 kft overspreads the terminals.

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.
