357 pm cdt Wed may 22 2019

Short term (this evening through Thursday night)
issued at 357 pm cdt Wed may 22 2019
showers will end tonight as an area of low pressure moves east of
the northland with high pressure taking its place for tomorrow
before another shot of rain arrives late tomorrow night as the
pattern remains active.

Low pressure was located over eastern south dakota this afternoon
with a warm front lifting into east-central minnesota and
northwest wisconsin. This low will track across northeast
minnesota overnight and out over lake superior by sunrise Thursday
morning. This will keep showers possible across the northland into
this evening with showers ending from south to north during the
late evening and early morning hours. A few thunderstorms may be
possible late this afternoon and early evening across northwest
wisconsin with a couple hundred joules of CAPE being in the area.

Skies will remain mainly cloudy through the night with winds
becoming light despite the low moving through. Lows will cool into
the 40s.

A few showers may linger across northern areas on Thursday, but
dry conditions will be in place by the afternoon hours as high
pressure builds in. Despite the high, skies will remain partly to
mostly cloudy with areas closer to the international border seeing
the best chance of some Sun by late afternoon. Skies will continue
to clear in northern areas during the evening hours, but the high
will shift east across lake superior Thursday evening as another
area of low pressure moves into the central plains Thursday night
and lifts a warm front into iowa. Isentropic lift and warm air
advection over the front will lead to showers spreading across
minnesota for Thursday night into early Friday morning. This
activity will move into areas along and south of us2 in minnesota
and much of northwest wisconsin by daybreak Friday. Temperatures
will be warmer despite the clouds Thursday with highs in the
middle 50s to middle 60s with lows in the 40s.

Long term (Friday through Wednesday)
issued at 357 pm cdt Wed may 22 2019
models are in very good agreement aloft and at the surface with the
handling of the potent upper low and its associated surface low. The
upper low moves through north dakota Friday, while the surface low
moves from eastern montana to eastern north dakota. Rain will spread
across the forecast area from south to north, with some
thunderstorms possible Friday afternoon. The upper low moves into
northern canada Friday night before opening into a long wave trof.

The surface low moves over northwest minnesota into northwest
ontario. The showers and thunderstorms will continue in the evening,
ending from south to north. Some showers will occur over the
northern half of the region as a secondary weak cold front moves
into this area. The showers will diminish Saturday morning as the
cold front weakens and lifts north into canada. In the afternoon,
high pressure moves over the region.

Model differences show up Saturday night with the handling of a
short wave trof moving quickly through the area, and its surface low
location QPF signal. The canadian has the most furthest south qpf
into the northern forecast area, the GFS touches the international
border, while the ECMWF is farther north into ontario. Used a blend
which acknowledges the canadian's more southern solution. The model
differences grow in magnitude Sunday with regards to the
strength depth of an upper level trof dropping south through south
central canada. The GFS is the strongest and has the most QPF over
the area, the canadian is weaker mainly dry until late afternoon,
and the ECMWF is very weak and completely dry. A blend was used a
result. The model discrepancies persist through Sunday night with
the upper level and surface features. The rain chances increase
Monday with a surface low moving toward the western great lakes. The
low center moves over northwest wisconsin Monday night with the
highest rain chances. Rain chances lower on Tuesday as the surface
low departs and high pressure begins to build behind it.

Aviation (for the 18z tafs through 18z Thursday afternoon)
issued at 1242 pm cdt Wed may 22 2019
widespread MVFR ifr conditions will persist this afternoon as rain
showers continue to work through the terminals. Lifr ceilings are
expected to persist at dlh through much of the period with
persistent flow off of lake superior before improving by mid
tomorrow morning. Hyr should see improvement to MVFRVFR for a
period late this afternoon before ceilings start to lower once
again. There is the potential for fog at most of the terminals
tonight in addition to areas of drizzle. Rainfall will be moving
out at this time and if fog develops, vsbys could drop to ifr lifr
but confidence was not high enough for that at this time. Winds
will diminish this afternoon and become light for the remainder of
the period, although hyr may become breezy again by late tomorrow
morning.

Marine
Issued at 357 pm cdt Wed may 22 2019
the small craft advisories will continue into the late evening due
to the high waves and gusty easterly winds. The waves and winds
subside overnight. Showers and areas of fog will affect the
nearshore waters tonight through Thursday morning, then end with
high pressure arriving.

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.
