631 am cdt Mon may 20 2019

Short term (today through Tuesday)
issued at 315 am cdt Mon may 20 2019
warmer but still seasonably cool temperatures and relatively
quiet conditions expected during the short term period. High
pressure will drift northeastward across the region today and
tonight with skies becoming mainly clear and temperatures much
warmer than yesterday. Highs will reach the middle 50s to low 60s
in northwest wisconsin to the middle and upper 60s in north-
central minnesota. Mostly clear and cool tonight as the low moves
across northern ontario. Lows in the low to upper 30s.

A longwave trough will take on an increasingly negative tilt as
it lifts through the southern and central plains Tuesday. Low
pressure at the surface and aloft will lift northeastward into
kansas and nebraska by 7 pm Tuesday. Isentropic forcing for ascent
in the warm sector of the system will bring precipitation
northward into minnesota and wisconsin during the day. The rain
showers may leak into the brainerd lakes by late Tuesday
afternoon. A considerable amount of dry air will be found over the
northland, which will need to be partially saturated before rain
reaches the ground. Have slowed the arrival of precipitation by
about 4 to 6 hours compared to the previous forecast with the best
chance of rain holding off until after 7 pm. In addition to the
rain, a deep mixed layer will tap into strong easterly flow aloft
creating strong wind gusts to near 30 knots in central minnesota
northeast toward the twin ports. Lower gusts are expected for much
of northwest wisconsin and the remainder of our minnesota zones.

Sustained winds of 15 to 25 knots are likely during the afternoon.

Highs on Tuesday should be able to reach the upper 60s in north-
central minnesota, near 60 degrees in the brainerd lakes, low 60s
in northwest wisconsin, and middle and upper 50s along the north
shore of lake superior due to the onshore winds during the
afternoon.

Long term (Tuesday night through Sunday)
issued at 315 am cdt Mon may 20 2019
a system will be staring us down heading into Wednesday as a
upper low ejects out of the great plains. The latest model runs
drift the surface low associated with this feature directly over
the northland which is a trend eastward comparative to prior runs.

Due to this new track, increased winds especially across lake
superior as the pressure gradient tightens up substantially on
wed thu. This system will bring moisture northward with pw's
around an 1", but will set the stage and prime the area for the
following system which arrives Friday with pw's which increase to
1.5" in conjunction with a lot more instability with MUCAPE of
1500 j kg sliding across the southern portion of the forecast
area. Both of these systems will increase the potential for
flooding in NW wisconsin especially since places received 2-3" of
qpe yesterday. The latter system also may bring stronger
convection and the potential for severe thunderstorms Friday
afternoon.

High pressure dominates for the weekend before the active swly
upper level jet continues to usher moisture laden systems into the
area next week.

Overall, temperatures return to normal ranges with highs in the
60s and lows in the 40s.

Aviation (for the 12z tafs through 12z Tuesday morning)
issued at 630 am cdt Mon may 20 2019
after a little patchy morning ifr fog - mainly at kbrd and khyr,
aVFR day on tap with light winds with no concerns for the
remainder of the TAF period.

Marine
Issued at 315 am cdt Mon may 20 2019
pressure rises and a retreating low will cause winds to elevate
to small craft criteria this afternoon for a few hours along the
north shore. A strong low pressure system will cross the region
Tuesday night through Thursday and may bring gale force winds
again as the low pressure tracks across lake superior. Another
strong system crosses on Friday.

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.
