Synopsis
Issued at 345 pm edt Wed sep 19 2018
unseasonable warmth will continue, with Thursday afternoon high
temperatures in the upper 80s to lower 90s. There will be a chance
of showers and thunderstorms Friday afternoon. Cooler temperatures
will filter in behind a cold front with highs only into the 60s on
Saturday, then mainly in the 70s next week.

Short term (this evening through Thursday)
issued at 344 pm edt Wed sep 19 2018
stable environment across CWA to prove formidable against upstream
convection. Perhaps a few stray showers or low chance storms in
far northwest towards daybreak associated with decaying convection
that should fire across northern ia southern mn after sunset. Warm
sector to become firmly established across much of CWA on Thursday
as upper level ridge centroid moves from the lower mississippi
valley to the carolinas. Modest 30 kts deep layer shear and mlcape
of 1500-2000 j kg could pose a small risk for strong storms in far
northern tier CWA midday afternoon Thursday. Warmest day of week
with far southwest CWA likely into lower 90s.

Long term (Thursday night through Wednesday)
issued at 344 pm edt Wed sep 19 2018
better deep layer shear and ramping instability ahead of surface
frontal passage on Friday with southeast third of CWA presenting
with greatest potential for storms growing upscale into linear
segments with damaging wind gust risk Friday afternoon. Timing
continues to be critical with overall limited time and areal
extent rather limited. Strong airmass exchanges behind frontal
boundary as surface ridge of northwest canada origin spreads into
the upper great lakes. Highs only into the 60s Saturday,
gradually moderating into the 70s next week. Overall low chances
showers early next week, but better chances Tuesday afternoon into
Wednesday as broad upstream upper level trough from central
canada into the plains sharpens.

Aviation (for the 06z tafs through 06z Thursday night)
issued at 115 am edt Thu sep 20 2018
some increasing mid and high cloud expected through the remainder
of the overnight as convective complex entering southern
wisconsin bypasses northern indiana to the north. Terminals remain
to the north of stalled frontal boundary this morning, but
diurnal mixing will allow rapid northward mixing of this front
into southern lower michigan today. Gradient should remain strong
enough this morning to prevent fog from becoming a big concern,
although cannot discount some MVFR vsbys at either terminal for a
time between 10z and 14z. Relatively unstable conditions to
develop this afternoon, but all mid upper level forcing of
significance will remain to the north. Lack of forcing combined
with rapid northward retreat of warm frontal zone continues to
argue for omitting any precip mention with the 06z tafs. Warm
sector south-southwest gradient to strengthen today with some
gusts to around 20 knots possible at ksbn this afternoon. Strong
inversion decoupling this evening should set the stage for
favorable llws criteria after 06z Friday morning, and this will be
addressed in more detail with the 12z TAF issuance.

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.
