River Flood Warning 77, NWS Paducah, KY

AREA FORECAST DISCUSSION
National Weather Service Paducah KY
249 AM CST WED NOV 18 2015

.SHORT TERM...(Today through Friday)
Issued at 231 AM CST WED NOV 18 2015

Gradient winds ahead of the line were gusting through the 30s mph
on average...with isolated reports of up to 45 mph at times. We
issued an SPS for such gusts/potential to cause minor damage thru
early morning hours as the line works into/across the
Pennyrile/WKY and SWIN.

Tabulated rainfall amounts are on track with 4 to 5 inches across
SEMO (isolated higher amounts)...where rain has all but ended.
Another 1-2" falling this morning as band marches on thru areas
east of MS river will spell storm total amounts in line with
models/forecast... 3 or 4" for remainder of Watch Area with
lesser amounts to 2" across our East. In collab with our
neighbors, we'll expire FFA across nearly all of SEMO and retain
for areas along/east of MS river where rain still is ongoing.
Tracking of back edge suggests rain will be over for entire Watch
area by 15z, so we'll make that adjustment as well. All rain
should depart FA by around 18z.

Afterward, High pressure works in and should gradually dry and
cool our atmosphere. We'll slide back to 50s/30s for the remainder
of the short term forecast period, to finish out the work week.

.LONG TERM...(Friday night through Tuesday)
Issued at 231 AM CST WED NOV 18 2015

A significant pattern change will occur during the long term period.
A strong 500 mb shortwave will dig southeast across the mid and
upper Mississippi Valley on Friday night/Saturday. A second weaker
shortwave may follow a similar path Sunday. In the wake of these
shortwaves, a quasi-zonal flow pattern is expected next week. This
sequence of events is a sharp departure from the high amplitude
western trough/eastern ridge pattern that has been common this month.

As far as the daily details, a strong cold front will sweep
southeast across our region early Saturday. Forcing associated with
the digging 500 mb shortwave may generate scattered showers late
Friday night and Saturday morning. In the wake of the front, rather
strong northwest winds will usher in the coldest air so far this
season. Both the gfs and ecmwf indicate 850 mb temps will hover from
minus 5 to minus 9 Saturday night through Sunday. This will
translate to daytime highs struggling to reach 40 on Sunday. Under a
1030 mb surface high, overnight lows on both Saturday and Sunday
nights will be in the 20s.

Monday through Tuesday, a zonal flow pattern is expected across much
of the country. This will result in a continuation of mainly dry
conditions with slowly moderating temperatures. Highs will
recover to the lower 50s by Tuesday, with lows in the 30s.

.AVIATION...
Issued at 231 AM CST WED NOV 18 2015

Strong gusty winds will persist ahead of an advancing wall of rain
as a low pressure storm system makes passage. South to southeast
winds 15 to 20 knots are forecast to occasionally gust to as high
as 30 to 35 knots at times...mainly out ahead of the pcpn. Winds
will then tend to decrease somewhat once the precipitation begins.
And that'll be a roughly 6 hour period of moderate to occasionally
heavy rain as it spreads eastward across the EVV/OWB terminals,
having departed CGI and working thru PAH at this writing. MVFR
Cigs and Vsbys will occasionally be reduced to IFR beneath the
heaviest rain. Pcpn effectively ends for all flight terminals
by/shortly after 18Z, after which gradually improving to VFR
conditions should commence.
