239 pm cdt Fri jun 23 2017

Short term (this evening through Saturday)
issued at 239 pm cdt Fri jun 23 2017
high pressure will settle in to the western high plains with the
gradient slackening just a bit over the area. This will allow
temperatures to fall into the 40s overnight as clouds will be on the
decrease this evening.

Saturday will be similar to today, well mixed and breezy as well as
cool. Likely a couple degrees warmer but still some upper 60s to
lower 70s in most locations as clouds will be less than today. A
weak wave will move through mn on Saturday so will have a small
chance for showers across parts of southwest mn and northwest ia.

Long term (Saturday night through Friday)
issued at 239 pm cdt Fri jun 23 2017
Sunday will see a decrease in winds as high pressure settles in.

With decent mixing will still see some northwest winds around 10
to 20 mph with the stronger winds across southwest mn.

Temperatures will again not change much but with a little more
sunshine it should be a pleasant day.

The almost september like pattern will continue through late next
week. This is in response to a series of waves near the canadian
border, which will keep the upper level jet farther south through
the northern and central plains. While temperatures will not be as
cool as today through Sunday, they will still be near or below
normal most days next week. The latest models are all fairly
agreeable swinging a wave onto the plains Tuesday into Tuesday night
so will have the best chance for rain and thunderstorms during that
time. While it is far from a perfect set up for severe weather,
strong winds and good turning in the 0-3km layer are expected but
mid and upper level winds for now are not progged to be very strong.

After this wave passes the models become less agreeable as the gfs
really digs in a strong wave Thursday into Friday while the ecmwf
and canadian are a little closer to zonal flow. Will not change much
during this time frame with a lack of consistency.

Aviation (for the 18z tafs through 18z Saturday afternoon)
issued at 1209 pm cdt Fri jun 23 2017
low endVFR ceilings will gradually rise through the afternoon
withVFR conditions after.

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.
