AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
1037 AM EDT Sat May 10 2014

...Forecast Update...
Issued at 1035 AM EDT Sat May 10 2014

Only made a few minor updates this morning to the current forecast.
Overall trends of PoP, weather, and sky are on track. The PV anomaly
causing the convection this morning is pushing east through southern
Illinois. All activity will be south and east, with rain/storm
chances diminishing as the subsident west side of the PV anomaly
works eastward into our area later today. Broad area of showers and
embedded thunderstorms currently stretches southwest to northeast
across our eastern CWA, with a few isolated cells to our north. Will
have to watch the convection moving northeast out of western
Tennessee to see how this will play into the afternoon forecast. It
is on the southern edge of the PV anomaly and the latest HRRR
continues to move it northeast but in a weakening state. The HRRR
also redevelops convection across central Kentucky late this
afternoon and early evening, which may be in response to this
approaching southwest convection combined with the PV axis being
directly over the forecast area. Have made some adjustments to the
PoPs this afternoon, but nothing major at this time.

.SHORT TERM (Now through Sunday)...
Issued at 300 AM EDT Sat May 9 2014

The synoptic pattern early this morning features a strong trough
pushing through the Upper Great Lakes.  An associated surface low
was centered across across southern Canada, with a surface cold
front extending southwest through northern
Indiana/Illinois/Missouri.  This front will slowly drift east today
as it washes out and lifts north on Sunday.

Convection continues early this morning across portions of western
and central KY.  This convection is being forced by a low-level jet
impinging on a remnant outflow boundary from convection last
evening.  This activity will likely continue through the morning
hours today, perhaps even expanding more in coverage as
synoptic-scale forcing associated with another ejecting PV anomaly
crosses the region.  The best coverage looks to be across southern
KY northeast into the Northern Bluegrass region.  Southern Indiana
will likely see the least amount of activity this morning.  The main
threats with these storms will be heavy rainfall and some small
hail.  In fact, will need to watch portions of southern KY closely
over the next few hours for some localized flooding potential as
storms continually train over the same areas (especially
Logan/Butler counties).

By late this morning into the afternoon, the main PV anomaly will
push northeast of the region.  The main synoptic cold front will
quickly wash out across southern IN and northern KY this afternoon
as it becomes parallel to the upper-level flow (which will be
transitioning to more zonal).  Therefore, with subsidence in the
mid-levels and no strongly convergent feature at the surface, think
additional development late this afternoon will be hard to come by.
While a stray shower/storm cannot be ruled out (especially across
southern IN or northern KY near the front), don't think it's worth a
mention in the forecast.  Therefore, have gone dry by late this
afternoon into this evening across much of the region.  Clouds will
likely linger across east-central KY through a good part of the day
keeping highs in the mid 70s, but sunshine should break out across
southern IN and west-central KY, which should help temps climb into
the upper 70s and lower 80s.

Guidance continues to weakly hint at some sort of an MCS developing
across the Central Plains today, approaching the Ohio Valley
overnight.  It appears that the main low-level jet axis will be
focused to the northwest of the region.  Additionally, the flow will
be starting to amplify with heights building across the region.
Therefore, am not sold that this system will make it this far, and
have lowered pops from previous forecast.  Will still leave some
slights in across the far northern CWA, but think most will stay dry
Saturday night into early Sunday.  Overnight lows will be in the low
to mid 60s.

Mother's Day is shaping out to be quite nice across the region.
What's left of the pesky, washed-out front will begin to lift north
in response to an approaching upper-level trough.  This front along
with some weak isentropic ascent may be enough to spark an isolated
shower/storm mainly north of I-64, but again this chance appears
quite slim.  Think most will stay dry with partly to mostly cloudy
skies.  Highs will be rather warm as thicknesses increase through
the day and we mix efficiently due to solid southwest flow.  This
should push highs into the middle 80s across most areas.

.LONG TERM (Sunday night through Friday)...
Issued at 323 AM EDT Sat May 10 2014

An active period of weather looks likely for a good portion of the
extended period...especially in the middle part of the work week.
Tonight's guidance still has inconsistencies among the various long
term model solutions.  However, a clear emerging trend in the data
shows a much slower progression of a strong mid-upper level wave
crossing the country early next week.  With this trend, it appears
that the beginning of the forecast period will be a bit drier and
warmer than normal.  As this trough axis passes through the region,
we expect to see ample rainfall with the associated cold frontal
passage along with a sharp cooling trend that looks to continue into
late next week.

With the slower progression of the upper level wave expected, we
expect drier and warmer conditions Sunday night through Monday
night.  In general, we have backed off PoPs considerably for Sunday
night and much of the day on Monday.  A continued southwesterly
fetch will bring more moisture and warmer air into the region.
While no real trigger exists for convective initiation, it does
appear that diurnal/differential heating will likely produce
isolated-scattered convection during the afternoon hours with
convection dying off in the evening.  Lows Monday morning will be
quite mild with readings generally in the middle to upper 60s.
Highs Monday look to warm into the middle to upper 80s.  Lows
Tuesday morning will be similar to Monday morning with readings in
the middle to upper 60s.

The upper trough axis will start to work into the region on Tuesday
with a cold front approaching from the northwest.  This will mark
the start of a very unsettled period of weather for the Ohio
Valley.  We should see a band of convection develop out to the west
of the area and then slowly work into the region Tuesday afternoon
and evening.  The boundary will likely stall out across the Ohio
Valley on Wednesday as a secondary wave rounds the base of the
trough and helps develop cyclogenesis across the lower Mississippi
Valley.  This low will ride up along stalled out front Wednesday
night into Thursday.  As this low passes northeast of the region,
much cooler air will rush into the area.  With this thinking, have
increased the PoPs considerably from Tuesday afternoon through
Wednesday night.  Temperatures on Tuesday will likely warm into the
middle 80s once again with highs on Wednesday only warming into the
lower to middle 70s.

By Thursday, the anomalous upper trough axis will push through the
region.  We expect to see unsettled weather continue, though
thunderstorms will likely be much more limited with mainly rain
showers being the primary weather threat.  It will be distinctly
cooler with highs only warming into the 60s.  Have gone well below
guidance here as the statistical guidance is likely going to play
catch up during the week.  The upper trough axis should clear the
region by Friday, but a deep cyclonic flow pattern looks to remain
over the Ohio Valley by late week and continue through next
weekend.  This will result in much much cooler conditions across the
region.  Latest guidance suggests highs in the upper 50s to the
lower 60s by Friday...with overnight lows in the 40s.

.AVIATION (12Z TAF Update)...
Issued at 642 AM EDT Sat May 10 2014

Convection continues across all TAF sites this morning as a
low-level jet continues to impinge upon a lingering outflow boundary
to the south.  These showers and thunderstorms will continue through
the morning hours, bringing mainly MVFR cigs/vsbys in the steadier
cores.  Given the lack of a focused area of thunderstorm coverage,
will continue to handle with -SHRA/VCTS wording and amend if any
better clusters look to affect a TAF site.  Cannot rule out some
brief IFR conditions, especially towards KBWG this morning, but
duration should be short thus will leave out for now.

The convection should reduce in coverage from west to east this
afternoon as the main upper-level wave pushes off to the east.  This
will allow all sites to go VFR by late this afternoon through
tonight.  Winds today will be out of the WSW at 8-13 knots.
