clear skies across the forecast area. Light winds over all but the
southwest. No changes to the going forecast except a few tweaks to
sky and updated latest sensible weather elements.

quiet weather through tonight and a windy Thursday highlight the
short term forecast.
Surface high pressure across the northern plains today will
propagate into the upper mississippi valley on Thursday. Dry and
quiet weather is expected across western and central north dakota
through tonight. A tightening pressure gradient ahead of a surface
trough across eastern montana will support a windy Thursday,
especially along and west of highway 83. Winds are expected to
remain sub-advisory as has been the trend, with peak gusts around
35 kts. The strongest winds are expected across the higher terrain
of southwest north dakota.

The 12 utc global and hi-resolution suites favor convective
initiation across eastern montana Thursday afternoon and into the
evening in association with an instability axis along a surface
trough. This convection is expected to propagate into western
north dakota overnight sustained by a low level jet and moisture
transport. SPC does have western north dakota in a marginal risk|
for severe storms Thursday evening and night. However, storms may
be weakening in intensity with the sunset and some capping as
they propagate into north dakota.
The rain shower and thunderstorm threat for Friday is a bit more
uncertain as the region may be between shortwaves. For Saturday,
rain showers and thunderstorms are likely with continued moisture
transport leading to precipitable water values above 1.50 inches
and the potential impact of a more significant shortwave. The
severe thunderstorm threat is highly dependent on heating if any
breaks in the cloud cover can be realized, further tempered by
weak shear. Another shortwave arrives on Sunday with another round
of rain showers and thunderstorms, again the severe threat being
limited by cloud cover and weak shear.
Looking ahead, cyclonic northwest flow aloft favors a period of
well below normal temperatures with highs in the 60s early the mid

vfr condition expected through the 00z TAF forecast period. High
pressure currently over eastern forecast area will continue to
move east. Southeast surface flow will develop by Thursday morning
across all TAF sites, and will be come gusty across the west 20 to
30 kts and central 15 to 25 kts by late morning early afternoon.
Kjms will remain around 15 kts or less Thursday afternoon.

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.
