Updated for 12z aviation discussion
Issued at 456 am cdt Mon may 29 2017

Short term (today and tonight)
issued at 410 am cdt Mon may 29 2017
today is expected to be cooler and breezy with increasing clouds,
scattered showers, and even an isolated thunderstorm possible. A
few stronger cells could bring down some wind gusts near 40 mph,
but not expecting enough instability for any severe weather today.

Tonight will be cool overnight lows about 5 degrees below the
seasonal average for late may.

Early morning satellite imagery with surface obs showed a counter
clockwise circulation over northern lake superior, with cyclonic
flow extending across all of minnesota and wisconsin as well. Low
clouds and drizzle were wrapping around this low, and should
overspread the region this morning. The abundance of cloud cover
will limit heating, so continued with cool temperatures today. It
will also prevent CAPE from building across the region, so unlike
Sunday, not expecting much in the way of deep convection. The best
chance for thunder is across southern minnesota. It will be
breezy, so could see some gusty winds with a passing shower, but
smaller dewpoint depression should keep any wind gusts sub-severe.

Long term (Tuesday through Sunday)
issued at 410 am cdt Mon may 29 2017
another day of isolated-scattered showers, breezy conditions and
below normal temperatures is on tap for Tuesday with deep cyclonic
flow still in place. Showers should be less numerous than today with
poorer lapse rates.

A surface ridge axis will reach the eastern central dakotas
Tuesday night and pass overhead Wednesday and Wednesday night.

Strong WAA on the backside of the axis will bring returning
moisture rapidly northward with the gulf remaining wide open. With
the trough stuck over the northeast and most of eastern canada, a
boundary will have difficulty lifting north of i-94 and will
likely stall in the vicinity of southern mn northern ia Thursday
through Saturday. The best forcing for ascent appears to be tied
to the LLJ impinging on the boundary over eastern sd Wednesday
evening, veering to southwestern mn and ia late Wednesday night
and remaining there through Friday, before again veering more
easterly Friday night. Pwats increase toward 1.5 inches and there
should be enough instability for thunderstorm development
throughout this corridor. Wind shear doesn't look particularly
impressive so any severe threat should be disorganized and tied to
peak heating, however repeated rounds of storms and seasonably
high pwats could lead to some heavy rain concerns.

Another approaching trough should bring a cold front through
Saturday Saturday night with cooler and drier air returning
Sunday and Monday.

Aviation (for the 12z tafs through 12z Tuesday morning)
issued at 456 am cdt Mon may 29 2017
vfr conditions should give way to MVFR as cold air moves across
the region and brings MVFR cigs. A few showers will pass through
the region as well, but they are expected to be light and brief.

The chance for thunder is too low to mention in the tafs. Skies
may clear later tonight, but kept MVFR CIGS for the northern taf
sites.

Kmsp...

ceilings will be tricky as there is not a uniform cloud deck
upstream to track toward msp. Should have ceilings above 1700 feet
for the duration of the TAF period with west northwest winds.

Outlook for kmsp
tue...VFR. Isolated MVFR -shra possible. Wind NW 10-20 kts.

Wed...VFR. Wind NW 5-10 kts.

Thu...VFR. Wind S 5 kts.

Mpx watches warnings advisories
Wi... None.

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.
