Short term (today and tonight)
issued at 330 am cdt Tue mar 28 2017
there are three concerns for the short term. The first is
additional fog development early this morning, high temperatures
today and the chance of rain late tonight.

A surface ridge stretches north to south along the western spine of
mn early this morning. Widespread dense fog has formed in eastern nd
and is pushing slowly southward into northeast sd. Short term
guidance keeps this just to our west through daybreak and no
headline is expected at this time. Farther east, areas of fog were
common over south central mn on northeast through west central wi.

So far, only isolated spots of dense fog are noted, with one being
at the keau airfield, which is typical in this pattern. There has
been an increase in mid level clouds across west central and
southwest mn, ahead of a mid level trough that stretches west to
east across central mn and wi. In addition there are also some high
level clouds streaming across the southern third of mn. Current
thinking is that any dense fog will likely be confined from near
kael to keau. Will continue to monitor for a dense fog advisory, but
not planning one at this time.

Once the h7 trough moves south of us by mid morning we will be
looking at a good deal of sunshine for the rest of the day. The 925-
850mb column is a degree or two warmer over that on Monday. Hence,
highs should be at or above what we experienced, which got out of
control in the twin cities with lower 60s. Mix-down from 850mb
supports 60-65 from the twin cities on wnw through krwf, kbdh and
kaxn. Readings to the east and south are more in the 55 to 60 degree
range. Guidance used to make the thermal gradient sharper included
an equal blend of bc adjmet, bc GFS and bc consraw.

The surface ridge will move off to the east of the fa early tonight
with increasing SE low level flow. It will be a warmer night with
lows in the upper 30s from the twin cities on wnw with 30-35 to the
north, east and south of kmsp. The third in a series of a strong
upper low in the southern stream will advance into the central and
southern plains overnight. The cams keep the leading edge of the
light rain almost entirely out of our fa until after 12z Wednesday.

Therefore, only slight chance pops reach SW martin county
through 11z.

Long term (Wednesday through Monday)
issued at 330 am cdt Tue mar 28 2017
the longer term concern remains the coverage of light rain
spreading over the southern third of minnesota into west central
wisconsin Wednesday into Thursday.

The deterministic models have pretty much come to a consensus of
drawing moisture into at least the southern third of minnesota
during the day Wednesday... And then moving it east as the northern
and southern stream phase enough to generate enough moisture
transport into the region. The 290k isentropic forecast actually
draws lower level saturation central minnesota and west central
wisconsin Wednesday night and actually drops a couple hundredths
of an inch of liquid in this region. It still remains a question
of how far north and west this will develop... And we did draw pops
a bit farther north into east central minnesota. Temperatures are
forecast to drop off into the mid 30s and thickness and lower
level boundary layer temepratures may get cool enough for at least
a rain/snow mix to the southeast late Wednesday night. Little or
no accumulation is expected however.

Following this system... Drier air returns to the region as the
upper flow pattern remains split. Models still draw a waves in the
northern stream across the region during the Saturday/Saturday
night time frame. There is a wide spread in strength and how much
moisture will be available. We retained the small pop for parts
of the cwa.

Models diverge further into early next week... With an increasing
threat of more widespread precipitation developing into early
next week. There remains a phasing issue with the western conus
trough and its counterpart to the north... So overall timing will
continue to be a problem. Overall... Temperatures should remain
above normal through the period.

Aviation (for the 12z tafs through 12z Wednesday morning)
issued at 644 am cdt Tue mar 28 2017
the only concern ahead is the br/fg for a few more hours this
morning. The worst conditions are at keau, although they are
starting to rock back and forth between a 1/4 and 1/2sm.

Otherwise, tempo conditions in MVFR br can be expected up to 15z.

Afterwards, it will beVFR for the duration of the period with
any ceilings AOA 120. Light ene winds this morning becoming ese
4-7 knots this afternoon.

Kmsp... Airfield will likely see a period of 4-5sm br between 12z
and 13z. OtherwiseVFR with similar winds/ceiling conditions as
those listed above.

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.
