Synopsis
Issued at 422 am edt Tue may 21 2019
another round of showers and thunderstorms is expected late
tonight into Wednesday. It appears this rainy pattern will
persist through memorial day with periodic chances for showers and
storms. Heavy rain is possible at times. Much warmer weather with
temperatures in the 70s to mid 80s from Thursday through early
next week.

Short term (this evening through Wednesday)
issued at 321 pm edt Tue may 21 2019
residual line of early morning showers has finally moved
northwards this afternoon. Persistent cloud coverage and cool
post-frontal airmass in place has caused temperatures to struggle
to reach the mid 50s. A secondary area of scattered showers is
developing along and south of hwy30 as an embedded shortwave
progresses through the lower ohio river valley. A few lightning
strikes have been observed across southern indiana which is much
closer to the shortwave and did where a few breaks in the clouds
where earlier on in the day. Chances for thunder in the CWA are
fairly low given our persistent cloud cover, and the track of the
shortwave will stay well south. These showers are anticipated to
diminish in areal extent in the 5-7pm edt timeframe. This will
start a relative lull in shower activity up to midnight.

After midnight, upper low moving across the central plains will
send a front, with ongoing convection along the front, across il
and into western in. As storms slowly move across the area through
the overnight hours and into Wednesday, they will gradually lose
upper level support as the right exit region of the jet moves
over the cwa. Front moves over the eastern zones by tomorrow
afternoon. Models show some increase in instability across NW ohio
and eastern in during the afternoon hours which could allow for
storms to become more efficient rain producers. Given that soils
remain saturated, any additional rainfall will likely prolong or
aggravate ongoing flooding.

Long term (Wednesday night through Tuesday)
issued at 321 pm edt Tue may 21 2019
Wednesday night into Thursday, the remnant central plains low which
will bring rain tomorrow will start to eject across the upper
midwest. This will send another front into the area and provide a
focus for yet another round of storms. With pwats remaining in the
1.25-1.5" range, this round of storms could bring periods of
heavy rain. As mentioned above, this will prolong or aggravate
ongoing flooding. Front becomes stalled over the area Thursday
night into the weekend as the upper flow becomes zonal in response
to a building sub-tropical high over the SE us. This will bring
period of showers and thunderstorms into the memorial day weekend
with temperatures in the 70s and 80s. Upper ridge breaks down
early next week and a vigorous low moves across the northern
plains.

Aviation (for the 18z tafs through 18z Wednesday afternoon)
issued at 124 pm edt Tue may 21 2019
precip from earlier today has largely dissipated across the
region. Expect another round of shra and possible tsra tonight.

This should impact the terminal sites after 06z. Wind shear will
be an impact between 06 and 12z for both sites.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
