230 am cdt Thu apr 19 2018

Short term
Today and tonight... Forecast confidence is high...

the snow has ended across the area this morning, and skies will
continue to clear from the north. North to northwest winds will
remain breezy today, as temperatures warm into the low to mid 40s.

High pressure will settle into the area tonight. Temperatures will
fall into the low to mid 20s, though given light winds, readings
will likely bounce around a fair amount during the overnight
hours. With those light winds, mostly clear skies, and plenty of
low level moisture, fog freezing fog development will be possible,
especially after midnight. Along with reduced visibility, any
freezing fog could result in a layer of frost on roadways,
resulting in renewed slick spots by Friday morning.

Long term
Friday through Monday... Forecast confidence is high:
high pressure overhead Friday will move slowly eastward over the
weekend into early next week. This high will bring dry weather and
plenty of sunshine to the forecast area through this period.

Temperatures will finally warm back to around normal for the
weekend... And might even be a couple degrees above normal by
Monday!
Tuesday and Wednesday... Forecast confidence is medium:
models show a low pressure and an associated cold front to move
through later Tuesday into Tuesday night. This may bring some
showers to southern wisconsin. Increased precip chances a bit, as
models are starting to come into better agreement with the
details of this system. Should see the milder temps continue
Tuesday ahead of the cold front, with temps falling back to around
normal or even a below normal Wednesday behind the departing
low front.

Aviation(09z TAF update)
Snow has ended this morning, and conditions are rapidly improving
toVFR. North to northwest winds andVFR conditions will prevail

possible Friday morning.

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.
