Short term (this evening through Friday)
issued at 328 pm cdt Thu apr 25 2019
a cold front crossed through minnesota and western wi this morning.

A shortwave trough allowed for post-frontal showers across southern
mn with many areas seeing 0.25 to 0.50 inch of rain. Clouds cleared
during the late morning with mostly sunny skies across most of mn
with the exception of the southeast. This has allowed for deep
mixing with temperatures exceeding guidance into the upper 60s and
lower 70s and dew points to plummet. Relative humidity values have
been able to fall into the 15-20 percent range across much of west
central mn. In addition, northwest winds will remain sustained near
20 mph and frequent wind gusts in excess of 25 mph are likely
through the early evening. Due to these conditions, a red flag
warning is in place through the early evening. The red flag warning
that was issued early this morning was expanded to include todd,
stearns, and kandiyohi counties.

A secondary cold front will cross through this evening. Cooler air
will follow this front with temperatures likely falling into the mid
30s to near 40 degrees overnight. High pressure will build-in Friday
night and continue shifting eastward on Friday. This will allow for
a mostly sunny skies through the early afternoon. H850 temperatures
will only be near 0-1c, so with deep mixing, temperatures are only
anticipated to reach the mid to upper 50s. Cloud cover will begin to
increase from the west during the late afternoon on Friday as the
ahead of the upcoming potent storm system.

Long term (Friday night through Thursday)
issued at 328 pm cdt Thu apr 25 2019
the main issue in the long term is the accumulating snow event
expected for Saturday across southern mn. Confidence is increasing
that accumulating snow will fall across the southern third of
minnesota during the day on Saturday.

By Friday night, a strengthening shortwave will be quickly moving
eastward through montana and will actually catch up to a great
lakes jet stream, leading to a coupled jet and an intensifying
system as it moves east across the dakotas. The latest model
trends have been to bring the track of the system slightly south
of the previous forecast, with the surface low set to move east
across central southern iowa Saturday. Strong frontogenetic
forcing for extreme southern mn in addition to an impressive pv
feature will lead to moderate to heavy precipitation during the
day on Saturday. As a result of this strong forcing, dynamic
cooling will allow snow to be the primary p-type for the southern
metro to the iowa border. Temperatures starting off Saturday in
the upper 30s will cool into the lower to middle 30s in this area,
where they will stay as the snow event unfolds. In general,
expecting a swath of 1-3" for just south of the twin cities, with
a 3-6" swath from the buffalo ridge through owatonna, albert lea
and northfield, including i-90. The strong pressure gradient will
also lead to northeast winds of 20-25 mph in far southern mn
during the snow, which will lead to limited visibilities.

Sunday will be dry and unseasonably cool with high pressure over the
upper midwest. The unseasonably cool conditions will likely persist
through the majority of the week. An approaching trough axis on
Monday will bring the first chances of rain next week. Temperatures
early Monday morning will be cool enough to support snow in central
mn and west central wi. Weak upper level ridging and surface high
pressure should allow for mostly dry conditions on Tuesday. Models
indicate an upper level trough over the western CONUS becoming
negatively tilted with a developing surface low somewhere in the
great plains. Models vary in solutions for the surface low and
precipitation chances Tuesday night and beyond. Thus, have left
blended guidance to account for precipitation possibilities.

Aviation (for the 18z tafs through 18z Friday afternoon)
issued at 1213 pm cdt Thu apr 25 2019
mid to high level cloud cover will continue clearing to the
southeast this afternoon with mostly clear skies expected through
tomorrow morning. Northwest winds will remain brisk through this
afternoon, gusting to near 25 kts. Winds will remain near 10 kts
overnight before increasing again during the mid-morning tomorrow.

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.
