Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
Issued at 735 pm edt Tue jun 19 2018
showers and storms will continue overnight tonight with the best
chance for lingering showers south of us-30. Humidity continues
overnight and into Wednesday, but Wednesday's highs will be cooler
than today's. A chance of showers and a possible thunder will
exist south of us-30 on Wednesday too. Thereafter, expect cooler
temperatures to round out the work week while the next chance for
showers and storms comes Friday and Friday night.

Short term (tonight and tomorrow)
issued at 217 pm edt Tue jun 19 2018
vigorous storms developing quickly this aftn within a zone of
substantial sfc based instability and weak forcing INVOF stationary
frontal zone. Lack of flow shear will keep potential storm severity
in check however similar to last evening water loading within high
moisture content airmass poses a local microburst threat especially
along ERN flank of small scale cold pools in more cluster convection.

Bulk of near term activity expected to follow south of us30 with
additional development later this aftn INVOF trailing outflow
boundary extending swwd from short convective segment over SRN mi.

More uncertain scenario overnight with varying cams based
solutions evolutions. Near term convective overturning and
stabilization after sunset suggests a waning in additional
shower storm development especially from late evening through wed
morning which lies counter to some deterministic solutions like the
rap which are much more bullish stemming from ewd progression of
large scale disturbance out of ia. At the least will give a nod
toward near term guidance trends and knock likely pops down
overnight.

Passage of upstream disturbance will push frontal zone south into
cntrl in wed. Some risk for additional showers south of us24 in
indiana mainly late morning into early aftn tied to diurnal
heating destabilization but focus appears much better through cntrl
in. Nonetheless drier and cooler across the remainder of the area
within post frontal airmass.

Long term (Thursday through Monday)
issued at 217 pm edt Tue jun 19 2018
development of vigorous upper low over the mid mo valley and ewd
evolution primary challenge this period. Surprisingly med range
spectral solutions fairly similar aloft and suggest dry wx holds wed
night and Thu before active frontal zone bucks back north into the
srn lakes Thu night with following showers storms through Friday
night.

Ridging sfc and aloft then build through next weekend with
moderating temps and dry wx.

Aviation (for the 00z tafs through 00z Wednesday evening)
issued at 735 pm edt Tue jun 19 2018
per SPC mesoanalysis page, the atmosphere appears relatively worked
over with lacking low and mid level lapse rates. Still, over 1000
j kg MUCAPE lingers in the area allowing for lingering
thunderstorms with heavy rain and gusty winds as the main threat.

Times of showers and storms are expected to continue during the
overnight with heavy rain becoming the main threat especially as
upper level divergence continues to the southeast and a shortwave
approaches from the nw. Flight conditions will continue to recede
towards low MVFR and possibly ifr as stratus builds in by
Wednesday morning.

Wednesday, a slightly more south-shifted boundary will continue
to slowly shift south behind the departing low pressure system
keeping the focus for any showers and possible storms mainly south
of us-30.

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.
