Short term (today and tonight)
issued at 343 am edt Wed may 24 2017
despite main sfc low being over in this morning, upper trough close
enough by along with sufficient mid-level moisture is leading to
showers lifting across central and eastern forecast area early this
morning. In general where rain is occurring it is light with only a
few hundredths but have seen around 0.20 inch at mnm and 0.10 inch
at esc. Skies have remained cloudy and that has kept temps uniform
in the 40s. H7-h5 upper trough over eastern ia per rap settles
southward to mo-southern in through midday. Swath of mid-level
moisture h7-h5 over roughly east half of forecast area along with
weak lift in that layer should continue to support some showers from
mqt to imt to the east this morning. As the upper support drifts
farther away from the area this aftn expect most of the showers to
taper off. Some hint that stratocu CU left over may try to yield a
few showers this aftn over same areas and perhaps over far inland
areas of western forecast area, but pretty low chance in terms of
both probability and coverage.

Northeast winds btwn the low over the ohio valley and high pressure
nosing in from hudson bay and northern ontario will keep temps well
below normal today. Temps will especially be cool near lk superior
where temps may have hard time reaching low 50s in some spots. Even
inland locations away fm lk superior modification will struggle to
reach much past 60 degrees. Normal highs for late may are in the low
60s near lk superior and near 70 along the wi border.

For tonight, upper and sfc lows over ohio valley may come far enough
north to bring chance of showers back over at least eastern forecast
area and possibly as far west as munising to ki sawyer and escanaba.

High pressure over the western area could lead to skies partially
clearing. However, since TD through today are only forecast to drop
to around 40, seems risk of frost would be lower but there could be
some fog instead. Kept mins in the 37-39 range at the lowest and put
fog in forecast. Clouds and any rain will hold up temps in the 40s
elsewhere.

Long term (Thursday through Tuesday)
issued at 450 am edt Wed may 24 2017
fairly active but low impact weather is expected through the long
term. Beginning thu, a lingering trough, cyclonic flow and weak low-
level instability should lead to isolated to scattered showers
diurnal showers over mainly the east half of upper mi. A mid-level
ridge finally builds in from the west and pushes the broad trough
and closed low east of the great lakes setting upper mi up for brief
period of drier weather Thu night into Fri morning. As the ridge
axis shifts E later on Fri some isold showers could return at least
to portions of the western CWA Fri afternoon into Fri night.

Expect shower chances to increase into the weekend as another
broad mid-level trough approaches from the west. This trough will
linger over the upper great lakes for at least the early part of
next week leading to another period of below normal temps along
with continued periods of showers as a series of shortwaves pass
through the region.

Aviation (for the 12z tafs through 12z Thursday morning)
issued at 747 am edt Wed may 24 2017
MVFR CIGS will continue at iwd and cmx this morning with lifr cigs
at saw due to upslope. With the arrival of drier air this aftn and
daytime heating mixing, CIGS will lift toVFR and scatter out at iwd
and cmx. CIGS at saw will be slower to improve, not reachingVFR
until tonight. There could be some sct-bkn low clouds try to form
late tonight at all the TAF sites as saturation occurs due to
nighttime cooling. Not enough confidence to introduce anything
other than MVFR CIGS at ksaw but will be something to monitor in
next TAF issuances.

Marine (for the 4 am lake superior forecast issuance)
issued at 343 am edt Wed may 24 2017
expect winds under 20 kts into this coming weekend as a relatively
flat pres gradient dominates the upper lakes.

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.
