Update
Issued at 1250 pm cdt Fri jun 23 2017
isolated showers will continue in northwest and west central
minnesota through mid afternoon, and breezy conditions will
continue throughout the afternoon.

Short term (today and tonight)
issued at 315 am cdt Fri jun 23 2017
challenges for the day include clouds and weak shower chances
within shear axis of NW flow aloft. Radar continues to show a few
echos this morning with a sprinkle reported at dvl.

Short wave responsible for the windy Thursday across the fa is
currently over SW ontario with the next potent wave spinning to
the south in northern saskatchewan. Shear axis between the two
systems will move across the area today with pwats recovering to
near an inch. Cams indicating a few quickly moving showers will be
possible mainly to the east of the red river valley throughout
the day. Mixing on model soundings will be near 850mb today with
20 to 25kts, much lower than yesterdays 40kt mixing from 700mb.

Should not need wind advisory but may see the dvl area near
criteria for an hour or two early this afternoon.

Cloud cover across the valley and to the east is expected to
begin to break up from west to east this afternoon. Some late day
sun should help temps into the mid 60s, possibly higher if clouds
break sooner.

Late tonight pops increase from NW to SE with the approach of the
next upper wave. A compact area of showers is expected with
forcing from the actual center of the upper low. Though placement
will need to be refined as it approaches.

Long term (Saturday through Thursday)
issued at 315 am cdt Fri jun 23 2017
for Saturday and Sunday the fa will continue to be influenced by
the NW flow aloft with well below normal temps for the end of
june. Saturday will be the cooler day with good agreement from
model guidance with the track of the upper low across the fa in
the first half of the day with a re-enforcing shot of cool
advection. A rather unseasonably cool day with showers and or
clouds persisting on the backside of the upper low. With 925mb
temps in the 5 to 10c range will optimistically go with highs
near 60f. Sunday will be a bit warmer with 925mb temps rising 5 to
10c however shear axis will linger over the area creating shower
chances in the afternoon.

Monday through Friday... The extended period begins with an upper
trof over the great lakes and continuing to shift east, with the
upper ridge rebounding over the northern plains bringing warmer
temperatures and quieter weather through Wednesday.

By Wednesday, a frontal system is expected to cross the area
bringing chances for more showers or storms. As the front passes
late Wednesday night, expect some slight cooling and breezy
conditions to end the period, with scattered showers and some
thunder possible.

Aviation (for the 18z tafs through 18z Saturday afternoon)
issued at 1250 pm cdt Fri jun 23 2017
isolated to scattered showers will remain in northwest and west
central minnesota for much of the afternoon. MVFR ceilings will
lift toVFR early this afternoon as ceilings scatter out from the
west. Expect breezy northwest winds in the 15 to 25 knot range
with gusts 20 to 30 knots, decreasing this evening. Expect
another round of showers overnight with lowerVFR ceilings and
development of MVFR ceilings in the early morning.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
