Synopsis
Issued at 352 pm edt Tue sep 18 2018
warm conditions can be expected through Thursday. Highs will
generally be in the lower 80s Wednesday, except a bit cooler near
lake michigan and into the upper 80s to around 90 on Thursday.

There is a slight chance for showers and thunderstorms this
evening and overnight then a greater chance on Wednesday, and
again on Friday. Temperatures will trend cooler, more seasonable
this weekend into early next week.

Short term (this evening through Wednesday)
issued at 349 pm edt Tue sep 18 2018
anticipate on very isolated convective activity through the
evening hours. Focused on northern and western tier of CWA where
pockets of MLCAPE to 1000 j kg and best orientation of prior
outflow boundary for more vertical updraft potentaial, rather than
remainder of area where outflow dominates. Additional showers
possible as upstream convective activity rides eastward atop
southeast states ridge and decays into more stable environment.

Additional convective development with greater potential coverage
by midday Wednesday amid plethora of boundaries and mesovorticies
within rapid westerly mid level flow.

Long term (Wednesday night through Tuesday)
issued at 349 pm edt Tue sep 18 2018
change with respect to forecast to bring lower pops by Thursday
afternoon with warm sector surging northward. Only far northern
tier has token chances by afternoon hours and surface maximum
afternoon temperatures as warm if not a couple degrees warmer
than today. Much stronger northern stream shortwave, currently
into pacific northwest now, to drive trailing frontal zone into
northwest CWA by midday, clearing far southeast CWA by evening.

This timing is slower than before and now present with the best
chance for strong to severe storms on Friday afternoon,
especially southeast CWA should timing remain consistent from here
on out. Deep layer 0-6 km shear values presently progged near 40
to 50 knots, largely owing to strong 50-60 kt mid level west-
southwesterly flow, heightening linear storm organization and wind
gust potential. Noticeably

Aviation (for the 18z tafs through 18z Wednesday afternoon)
issued at 1256 pm edt Tue sep 18 2018
convective activity likely to remain suppressed amid outflow
dominant environment and nominal instability across northern
indiana. Concern remains for brief visibility reduction near
sunrise in shallow patchy fog, though overall any reductions
should be minor brief. Later forecast issuances to further assess
thunderstorm potential later Wednesday afternoon.

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.
