Long term (Tuesday night through Sunday)
issued at 355 am cdt Mon aug 26 2019
Tuesday night through Thursday night
for the beginning of the long term period, it is indicated by
guidance that the trough axis will be progressing through eastern
north dakota and northwestern minnesota . This trough axis will keep
precip chances for Tuesday night into Wednesday. Due to northwest
flow and limited instability, it is unlikely that this precip will
be convective. However, if there is forcing later in the day on
Wednesday during peak heating, an isolated rumble of thunder can't
be ruled out. Winds will also be very breezy for Tuesday night into
Wednesday out of the northwest with gusts in the 20 to 30 mph range
possible. Temperatures will remain cool to mild on Wednesday in the
60s to near 70. Temperatures for Wednesday night will be near
normal. For Thursday, northwesterly winds will be breezy again with
the passage of a secondary cold front. Despite this frontal passage,
conditions look to remain dry with temperatures falling from the 70s
to the 60s and 50s in the evening into the early part of the night.
Temperatures will fall to the 40s area-wide during Thursday night.
Friday through Monday
the beginning of the weekend looks to be dry and cooler behind the
cold front. Highs on Friday will be in the mid to upper 60s, about
10 degrees below normal. Friday night will potentially be cooler
with lows in the mid to lower 40s across the area. Due to scattered
cloud cover, it is unlikely that frost will be of concern but is
something to keep an eye on over the next several days. Saturday
will be slightly warmer with high pressure dominating over the area.
For Sunday, some isolated rain chances return due to a small
shortwave suggested by guidance. It is unclear if the mode will be
convective or not, but daytime heating may be sufficient to produce
some thunder chances. Embedded shortwaves keep rain chances in the
forecast for Monday with highs remaining in the 70s.

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.
