Short term (today through Wednesday night)
issued at 212 am cst Tue nov 21 2017
surface analysis at 2 am shows a deep 984mb low just north of lake
superior in southern ontario with a trailing cold front extending
southward through central and southwest wi into ia. A secondary cold
front was pushing southeast out of northern mn dakotas.

Temperatures across the area as of 2 am ranged from the middle 30s
to middle 40s.

For today, that cold front over northern mn dakotas will surge
southeast across the area this morning which will usher in some
clouds and more impactful, gusty northwest winds and much colder
temperatures. Tight pressure gradient cold air advection downward
momentum will yield northwest winds in the 20-30 mph range with
gusts 30-40 mph. Not thinking a wind advisory is needed at this time
but will monitor wind gusts closely. Also, looks like any snow
showers associated with the frontal passage should remain over far
northern wi upper mi. Cannot rule out a flurry or two northeast of i-
94 in steep low level lapse rate environment, but opted to keep a
dry forecast for now. So, plan on a cold blustery day for the area
with highs only in the upper 20s to the middle 30s.

Winds die down toward evening as a ridge of high pressure moves in.

Otherwise, look for a mostly clear cold night with lows dropping
into the teens.

Wednesday starts off mostly sunny, but plan on increasing high mid
clouds through the day in response to warm air advection isentropic
upglide ahead of low pressure dropping southeast through the
dakotas. Highs are expected to be on the cooler side again with
readings in the upper 20s to middle 30s.

Mid-level trough weak surface low continues to drop southeast
through the area Wednesday night. Increasing pv-advection isentropic
upglide will result in a slight chance for some very light snow,
mainly along and north of i-94.

Long term (thanksgiving day through Monday)
issued at 212 am cst Tue nov 21 2017
a weak cold front slips through the area for thanksgiving day
resulting in a windshift and a few clouds. Otherwise, temperatures
will be near seasonal norms, in the upper 30s the the lower 40s.

Strong low pressure tracks across southern ontario Friday, drawing
warmer downsloped plains air into the region on breezy southwest
winds. A cold front from this low drops through the area later
Friday afternoon for the likelihood of some rain. Otherwise, expect
highs in the middle 40s to the middle 50s.

Weekend looks colder dry as canadian high pressure dominates the
upper mississippi river valley region. Look for highs mainly in the
30s. Monday looks a tad warmer with highs in the mid 30s lower 40s.

Aviation (for the 12z tafs through 12z Wednesday morning)
issued at 600 am cst Tue nov 21 2017
a strong, brief burst of northwest winds will move southeast
through northeast iowa and southwest wisconsin. Wind gusts will be
up to 45 knots. These winds will move southeast out of the area
by 21.14z. Once these winds move through the wind gusts for the
remainder of the morning will range from 30 to 35 knots.

A broken layer of 2500 to 3500 foot clouds will move through the
taf sites through early this afternoon. These clouds will affect
krst from 21.13z to 21.18z and klse from 21.14z to 21.15z.

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.
