Synopsis
Issued at 1103 pm edt Tue aug 20 2019
a cold front will drop south through the region Wednesday with a
chance of showers and thunderstorms, especially south of route
24. The front will stall south through central indiana on Thursday
with one more 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 (this evening through Wednesday)
issued at 252 pm edt Tue aug 20 2019
focus of short term is complex of showers and storms working
through western parts of the forecast area at the start of the
period. Thus far, storms have remained below severe limits with
outflow boundary now working well ahead of the line, causing
lightning activity to decrease as well and warming cloud tops.

That being said, there could still be a few pockets of storms that
tap the moderate instability as the gust front continues to work
out away from the storms with an isolated strong locally severe
wind gust mainly soutstillh of us 24. Previous updates had this
in hand and no plans to deviate at this point unless trends
dictate as such. Another potential area for redevelopment could be
with actual MCV that has become orphaned as the main lines races
east. However, considering there won't be much chance to recover
in the west, doubt there is any threat.

After the line exits remainder of the night into first part of weds
should be dry. With soupy airmass and potential leftover outflow
boundaries can't rule out a stray shower or storm popping up here
and there, warranting low pops. Cold front will begin to sink into
the area on Wednesday with chance for showers and storms across the
south. No risk for severe weather with best instability and dynamics
south.

Long term (Wednesday night through Tuesday)
issued at 252 pm edt Tue aug 20 2019
a cold front should be pushing across the area at the start of the
period with chances for showers and storms sinking south with it
during the evening hours. Slight chance to chance pops still
warranted until this feature departs. The front will stall out to
the south with one more wave rippling along it to bring a chance
for showers and storms south of us 30. Then high pressure will
build in across the region and remain through much of the
remainder of the forecast period, bringing cooler and much less
humid conditions.

Return flow begins to setup late Monday into Tuesday to bring
chances for showers and storms back into the forecast.

Aviation (for the 00z tafs through 00z Wednesday evening)
issued at 705 pm edt Tue aug 20 2019
kiwx radar indicating scattered showers and thunderstorms have
exited the area this evening and will lead to a dry forecast this
taf cycle. Forecast soundings have decent surface based inversion
developing overnight with ample low level moisture still in place
bringing potential for low stratus toward the early morning hours.

Will follow along with latest guidance and introduce a few hours
of ifr at both sites. Light and variable winds tonight will become
westerly during the day Wednesday.

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.
