Flash Flood Warning 66, NWS Paducah, KY

224 AM CDT FRI JUL 29 2016

.SHORT TERM...(Today through Sunday night)
Issued at 210 AM CDT Fri Jul 29 2016

As a surface trof of lower pressure works across the lower Ohio
valley today, it will help focus updrafts in high CAPE, diurnally
charged/souped environ, for scattered showers/thunderstorms with
locally heavy rains possible, and a marginal risk of svr storms.

By the weekend, H5 heights start to ease back up, with surface
high pressure over the Great Lakes. However, overall height falls
further up the Ohio Valley, and height rises in the High Plains,
means the teleconnected flow pattern will be nwlys aloft across
the mid Mississippi valley, which will be an enabling flow for
initiating mainly diurnal shower/storm activity. Highest pops will
be around the rim of the high pressure, ie across our south and
west, tapering to lowest pops north and east, closer to the
surface High.

Seasonal late July temps will finish out the weekend/month.

.LONG TERM...(Monday through Thursday)
Issued at 210 AM CDT Fri Jul 29 2016

A warmup to more extreme heat/humidity is anticipated next work
week as the Height falls over the mid and upper Ohio valley shift
eastward, with ridging High Plains heights working their way
across the middle and upper Mississippi valley. The net result for
us will thus be a building of heat/humidity with apparent temps
reaching or exceeding triple digits on the daily.

Accompanying the extreme heat/humidity, will be daily storm
chances, esp during the charged diurnal hours of the pm-evening.
Monday will be particularly wet, with good coverage of
showers/storms along a warm sector developing/lifting across the
area in response to surface Low pressure taking shape in the
Plains states. Daily storm chances continue unabated for the
remainder of the week, with high PW's offering locally heavy rain
potential with any time storms.

.AVIATION...
Issued at 210 AM CDT Fri Jul 29 2016

After the pre dawn patchy fog/low cigs (developing) restrictions,
anticipate daylight improvement with return to VFR conditions
eventually. However, daily storm chances will enhance during the
peak heating hours, with vicinity storms carrying associated
potential restrictions thru the evening hours.
