Synopsis
Issued at 153 am edt Wed aug 21 2019
a cold front will drop south through the region today with a
chance of showers and thunderstorms, mainly south of route 24. The
front will stall south through central indiana on Thursday with a
weak system moving through to bring a chance of showers.

Otherwise, cooler and less humid weather is in store for Thursday
through Saturday.

Short term (today through Thursday night)
issued at 341 am edt Wed aug 21 2019
a cold front was over wisconsin and was moving southeast. A line
of showers was associated with the front and will move southeast
today. Ahead of the front, areas of fog had developed where skies
had cleared with visibilities generally between 1 and 3 miles
north of a line from rochester to warsaw to hillsdale. The fog
has been locally dense in a few spots, but is not expected to
become widespread dense fog. The fog will mix out after daybreak
and should not be an issue later this morning. Otherwise, the
convective allow models were really holding back on showers and
storms today in lieu of development tonight over southern areas.

This south area should stay active Thursday as a wave develops
along the front given a scenario that is supported by the NAM and
also by the ecmwf. Any storms should end by midnight, although
lingering showers may persist until close to daybreak Friday
morning.

Long term (Friday through Tuesday)
issued at 341 am edt Wed aug 21 2019
a large surface high pressure area will build in from canada late
this week and bring 3 days of fair skies with cool, dry and less
humid conditions from Friday through Sunday. An unsettles period
is ahead early next week as warmer and more humid air spread back
into the region with shower and storm chances beginning Monday.

Aviation (for the 06z tafs through 06z Wednesday night)
issued at 157 am edt Wed aug 21 2019
continued concern for early morning period of ifr flight
conditions at ksbn and kfwa. At ksbn the more shallow nature of
moisture and greater radiational cooling potential, per satellite
trends, suggests that br a greater concern over low stratus layer.

At kfwa stratus remains a concern given... Later clearing,
upstream 1500 ft cloud layer and 10-15 knots flow mixing in
boundary layer per latest hrrr and rap soundings. Bottomline is
tempo ifr forecasts remain intact. Low chance for
showers thunderstorms midday afternoon remain too low for mention
at this time.

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.
