Short term (this evening through Sunday)
issued at 242 pm cst Sat nov 18 2017
skies have cleared through the day with strong subsidence behind the
upper trough exiting to the southeast. Despite low-level cold
advection and brisk northwest winds, the increasingly sunny skies
have helped bump temps up into the upper 30s to low 40s. With high
pressure spreading across the area tonight and Sunday, quiet
weather is expected. A bit more cloud cover will persist into
tonight over north-central wi as an upper shortwave drops
southeastward. With mostly clear skies across much of the rest of
the area tonight, temps should drop into the teens to low 20s,
recovering back into the 30s in most spots on Sunday.

Long term (Sunday night through Saturday)
issued at 242 pm cst Sat nov 18 2017
all in all, it's shaping up to be a fairly quiet weather week for
holiday travelers across the upper midwest, although with a few back
and forth temp swings and low-end precip chances.

Monday still looks mild, with 925 mb temps rising into the 6-8c
range and south to southwest winds. Highs should reach into the 40s,
with low 50s in some river valley locations.

A strong upper shortwave trough diving towards the great lakes will
drive a cold front through Monday night, with a surge of low-level
cold advection in its wake into Tuesday morning. It's not out of the
question that a few snow showers could occur as the front drops
through, but otherwise expect a much cooler Tuesday with highs in
the 20s and 30s along with gusty northwest winds. Cool temps will
continue into Wednesday under high pressure. Both the 18.12z
gfs ECMWF swing an upper shortwave cold front through late Wed wed
night. The ECMWF actually generates some light precip aided by
strong mid-level warm advection, but at this time, confidence is
low in any precip occurring.

Thanksgiving day is looking dry and seasonable as high pressure
spreads southeast from the northern plains. Confidence is a
little lower for temps late this week, with the ECMWF now showing
cooler 850 mb temps spreading back across the area thanksgiving
day behind the cold front thanks to a stronger, slightly more
amplified upper shortwave trough passing to the north. The ecmwf
is then slower bringing warmer back northward as the low-level
flow turns southerly on Friday. Temps should rebound on Friday,
but just how much is the question. Stuck close to consensus given
the model spread, with highs in the 40s. By Saturday, another low
pressure system cold front is expected to pass across the region,
but confidence is low in the details.

Aviation (for the 06z tafs through 06z Sunday night)
issued at 1127 pm cst Sat nov 18 2017
persistent area of clouds over wisconsin has been very reluctant
to move east this evening. This has brought aVFR ceiling to klse
with MVFR conditions not far away. Satellite shows these clouds
have a slow southeast movement to them and will keep aVFR ceiling
in until 19.09z with the expectation that the low level ridge will
move east enough to push the clouds far enough east to not be a
concern. Once the ridge moves in and becomes the dominant feature,
only some occasional high level clouds are expected through Sunday
evening. The northwest winds will drop to below 10 knots overnight
and then swing around to the west southwest on the back side of
the ridge Sunday morning.

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.
