Synopsis
Issued at 430 am edt Sun aug 19 2018
patchy dense fog will lift early today. Under a mostly sunny sky,
temperatures will rebound into the lower to middle 80s this
afternoon. A low pressure system will then bring widespread rain
and storms to the region late Monday into Tuesday followed by dry
and cooler weather Wednesday and Thursday.

Short term (today and tonight)
issued at 422 am edt Sun aug 19 2018
patchy dense fog had formed overnight with ideal radiational
cooling under mostly clear skies and with light winds. The ground fog
will burn off by 800 am edt as the lowest layers mix quickly out.

A weak upper level ridge will build into the region today and
keep temperatures warm with highs in the 80s. There is a very
small chance for a storm this afternoon with daytime heating over
northwest indiana and far southern lower michigan; however, have
opted to keep storms out of the forecast given weak large scale
subsidence and somewhat of a mid level cap around 700 mb.

Long term (Monday through Saturday)
issued at 422 am edt Sun aug 19 2018
an upper level system will move out of the central plains today
and then into the area Monday. This system will bring another
round of showers and storms Monday into Tuesday. Limited unidirectional
shear with tall thin capes will limit severe storm potential.

Although a isolated storm is possible with strong gusty winds, any
storm threats should be mainly from locally heavy rain that may
cause some local flooding. Conditions will clear out behind the
low pressure area for Wednesday and Thursday as high pressure
builds in and brings cooler and less humid weather. Lows should
drop well into the 50s by Thursday morning.

Aviation (for the 12z tafs through 12z Monday morning)
issued at 615 am edt Sun aug 19 2018
patchy fog has developed once again across northern indiana,
although this morning the main focus has been across NW indiana.

Vsbys vary widely across the region, and to this point ifr MVFR
vsbys have been short-lived at ksbn overnight. Easterly flow along
southern periphery of great lakes anticyclone appears to have
drawn in slightly drier low level air across NE indiana and nw
ohio which has largely limited fog potential to this point. As was
the case yesterday morning, expecting fog across NW indiana to
diminish shortly after 12z. Short-lived ifr MVFR vsbys are a
possibility through 12-13z at ksbn and will monitor trends over
next hour to determine if any tempo inclusion is needed early this
morning. Otherwise, quiet weather today with just a very low
chance of isolated shower this afternoon. Some uptick in weak low
level easterlies today should keep lake breeze west of ksbn, with
more pronounced lake breeze convergence across west central lower
michigan. A weak wave in northwest upper flow may also bring a
slightly greater chance of an afternoon shower across south
central southeast lower michigan. Will keep tafs day with these
potential focusing mechanisms remaining north of the terminals.

Quiet weather tonight and will likely not include any fog mention
due to slight uptick in low level flow.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
