Area Forecast Discussion
National Weather Service Paducah KY
230 PM CDT FRI APR 29 2016

.SHORT TERM...(Tonight through Sunday night)
Issued at 230 PM CDT Fri Apr 29 2016

An unsettled period is still forecast. An upper low will move out
of the central Rockies into the central Plains tonight. A warm
front extending ESE from low pressure over KS will lift north
toward the area tonight, continuing north through the area
Saturday. After an evening lull in convective activity as the
first round of showers/storms departs, expect an increase in
chances again overnight as the next wave moves toward the area.
Late night / early Saturday morning PoPs peaking at categorical,
should taper off by Saturday afternoon. Will continue with chance
to likely PoPs Saturday night with a surface front moving into the
area by 12z Sunday. Drier air starts to work in from the west
Sunday, so lower PoPs with time from west to east, best chances
Sunday west KY into southwest IN. Convective chances ending Sunday
night. Could be a few strong possibly severe storms this weekend.
Used a blend of the EC/GFS/NAM once again to level off each models
detail. Temps continue to be a blend of MOS and existing forecast

.LONG TERM...(Monday through Friday)
Issued at 230 PM CDT Fri Apr 29 2016

Models remain in some disagreement on some potential precipitation
chances early next week. GFS and Canadian show an upper level trof
moving across the middle Mississippi/lower Ohio valleys on Tuesday,
while the ECMWF is about 24 hours slower with this feature.  Models
generate some light scattered QPF ahead of this trof, and despite
its slower solution, the latest ECMWF does somewhat agree with the
GFS that the best potential for some showers would be Monday night
into Tuesday.  Included just some small chances for this time period
in our south/southeast counties where some better moisture would be
available. Our far eastern counties could see a few showers
Wednesday as the trof moves through combined with some daytime
heating, so included some slight chances for showers.  Overall
confidence is pretty low for these precipitation chances, but with
whatever does occur, so far it looks like amounts would be

Confidence remain pretty low late in the week as the GFS swings a
cold front and some precipitation into the region by Friday, while
the ECMWF keeps any precip east of our region and builds high
pressure into the area. Opted to keep the rest of the extended dry
for now, and we will keep looking for the models to latch on to a
more coordinated solution.

Numerical guidance indicates temperatures will be fairly seasonal
for the new work week, with highs in the middle 60s to middle 70s,
with overnight lows in the upper 40s to lower 50s.


Issued at 1239 PM CDT Fri Apr 29 2016

Widespread showers and embedded storms expected south of a KCGI-
K2I0 line with some lighter rains just north. Expect mainly VFR
cigs, with tempo MVFR to briefly IFR vsbys with heavier showers
over SEMO into west KY. The back edge is making quick progress
east over southern MO, northern AR, thus will taper off chances by
late afternoon. Winds will remain east generally aob 10 kts.
Overnight, have an evening lull, then precip chances return
later, with MVFR conditions likely with showers. Winds will veer
more to the southeast, some gusts 15-20 kts possible into Saturday
morning. Thunder possible as well.
