Area Forecast Discussion
National Weather Service Louisville KY
626 PM EDT Tue Apr 2 2024

.KEY MESSAGES...

* Severe storms remain likely into this evening. Damaging winds,
  large hail, and tornadoes are all possible. Localized flash
  flooding is also possible in areas impacted by repeated heavy
  rainfall.

* Rain on Wednesday could mix with or change to snow Wednesday night
  into Thursday morning. A light accumulation of snow cannot be
  ruled out, but significant impacts from snow are unlikely.

* Quiet weather expected Friday into next weekend with increasing
  chances of below freezing temperatures Saturday morning.

.MESOSCALE...
Issued at 624 PM EDT Tue Apr 2 2024

Squall line with embedded supercells has moved through southern
Indiana and now pushing across central Kentucky. QLCS tornadoes
continue to be the most impactful threat and Tornado Watch 78
remains in place until 2Z. Have cleared a few southern Indiana
counties behind the line.

Progress will be slow as storm motion is nearly parallel to the line.
So far we have not had any flash flooding but will continue to
monitor.

&&

.SHORT TERM /THROUGH TONIGHT/...
Issued at 407 PM EDT Tue Apr 2 2024

Severe weather threat is currently ramping up as storms try to
become more organized along/just ahead of a cold front in the Wabash
Valley. Morning and midday convection left behind quite a bit of
cloud cover, but that has scoured out and allowed temps to warm
quickly into the lower/mid 70s with several hours of daylight
remaining.

Storms struggled to get organized until the last 30-45 minutes, with
some of the storm motion keeping storms along or even behind the
effective boundary. Over the next several hours, the instability and
shear profiles will enable any storm that can stay on or ahead of
the front to easily go severe. All severe threats are on the table,
including damaging winds, large hail, and fast-moving, possibly
strong tornadoes. Boundaries left behind by earlier storms will
likely be the main focus for tornadoes. Tornado Watch 78 is in
effect until 10 PM EDT, though the threat will diminish earlier than
that for our northern and western counties as the front pushes
through.

Flood Watch until 00Z is a little tricky as most of the heavier rain
from the earlier storms fell just outside the watch area. Storms
this evening look progressive enough, and the heaviest rainfall is
not expected to repeat over the hardest hit areas from earlier, so
will not expand the watch at this time. However, with neighboring
counties still under a Flood Watch, will maintain status quo for
now.

Temps crash behind the front overnight as strong cold advection
takes hold. After morning lows in the lower 40s on Wednesday, we
will struggle to crack 50 degrees in the afternoon. Winds at a
solid 15-20 mph with gusts near 30 mph will make it feel closer
to 40 than 50 throughout the day. Deep cyclonic flow and a strong
cold pool will support widespread light rain showers, especially
Wednesday afternoon. Could even see some graupel or small hail given
the steep low-level lapse rates.

&&

.LONG TERM /WEDNESDAY THROUGH TUESDAY/...
Issued at 407 PM EDT Tue Apr 2 2024

Synopsis...Large-scale mid-level pattern height will remain largely
amplified during the long term period. Initially, broad upper
low/longwave trough will be anchored in the East CONUS as bouts of
shortwave energy continue rotating around its axis. Further west,
weak upper ridging will exist across the Rockies with positive
height anomalies across the northern Plains/southern Canada and
another upper low carving its way into California coast. At the
surface, occluded low pressure system will slowly move eastward from
the Great Lakes to the Northeast US keeping the Ohio Valley under
cool, windy, and showery conditions for most of the second half of
the week. During the weekend, the height anomaly configuration will
resemble an Omega blocking pattern as the features at play slowly
progress to the east, although the strongest portion of the jet will
zonally extend across the southern half of the Lower 48. As a
result, the mid-level ridge will approach the forecast region with
surface ridging nosing in from southern Canada/Upper Great Lakes.
The pattern will be speed up Sunday into next week as West Coast
upper low moves inland while the mid/upper ridge and associated
surface high pressure get pushed to the eastern seaboard.

Model Confidence/Evaluation...Most of the long term period will be
characterized by above-average model agreement as most of the
deterministic guidance consulted has similar output solutions
regarding the Omega blocking pattern and the position of the
synoptic features. Forecast uncertainty starts decreasing Sunday
into next week as models handle differently the inland trajectory of
the West Coast upper low, possibly due to its interaction with
shortwave energy upstream, and to a lesser extent the strength of
the downstream East CONUS upper ridge. The trajectory of the upper
low will ultimately determine the position of the attendant surface
low pressure and attached fronts which will influence the amount of
cloudiness or any weather next Monday, April 8, when the solar
eclipse will occur. As mentioned in the previous discussion, the GFS
still hints at a upper low farther east (higher probability of
cloudiness and rain) while the position of the upper low in the
CMC/ECMWF solutions is more to the west (lower chances of cloudiness
and rain).

Wed Night - Thursday...Surface low pressure and attendant low- to
mid-level vorticity impulses will move down from Lake Michigan to
southern Ohio during this period keeping the lower Ohio Valley under
persistent cloudiness with intermittent showers and breezy WNW
winds. The main forecast reasoning has not changed much as prog
soundings still show a saturated column into the DGZ early Wednesday
evening with falling surface air temperatures, low freezing levels,
and steep low-level lapse rates. Therefore, anticipate in the first
few hours of Wednesday evening liquid-precipitating, shallow
convective cells to still pose a threat of sub-severe gusty winds,
lightning, and some small hail with a quick transition to brief
rain/snow showers (possible some graupel) overnight as mid-level dry
air entrainment takes over and surface air temperatures/freezing
levels keep falling. At this moment, there could be some dusting of
accumulation over elevated surfaces early Thursday morning with no
significant impacts otherwise. Clouds, intermittent light showers
(mostly liquid), and breezy winds will continue during the day on
Thursday; however, the track of the surface low argue for a heavier
showers over the Bluegrass area given the track of the surface low
and attendant forcing. GFS forecast soundings over the Bluegrass
during Thursday afternoon hint at a renewed chance of heavier showers
(compared to the rest of the forecast area), low lightning chances,
and possibly some hail and enhanced gusty winds as cooling mid-level
temps will steepen low-level lapse rates and forcing promotes deeper
saturation into the DGZ. If heavier showers do occur, there is a non-
zero chance of a brief period of frozen hydrometeors based on low
freezing levels and additional effect of dynamic cooling. Finally,
went a few degrees below guidance for highs on Thursday but still at
or above convective temperatures for that matter.

Friday - Sunday...Friday still looks quite cloudy and somewhat
breezy, although the wind will slow down compare to Wednesday and
Thursday values. Precipitation chances will also largely decreased
for most as increasing mid-level heights and subsidence aloft start
to erode the depth of the moisture layer. As a result, a few breaks
in the cloud cover could allow highs to climb around the 50 degree
mark, but still below average for this time of the year. Increased
presence of surface ridging will allow clearer skies and weaker
winds, so that lows Friday night are still on track to be or below
freezing levels (especially over southern Indiana). Therefore,
frost/freeze headlines could be needed for Friday night/Saturday
morning. A warming trend with dry weather is anticipated for
Saturday and Sunday. Last but not least, action stage or minor river
flooding across the Ohio cannot be ruled as HEFS/GEFS/NAEFS hint at
increasing probabilities of those categories.

Next Week...Big question will be chances of rain and any cloudiness
on Monday due to the solar eclipse. As mentioned above, there is at
least a low chance of light rain showers and clouds over the southern
Indiana and northern Kentucky as a warm front lifts through the
region. But again, there is enough variability and the forecast
windows is still so far out that confidence in the forecast is still
low. So, stay tuned for new updates during the next coming days.

.AVIATION /18Z TAFS THROUGH 00Z THURSDAY/...
Issued at 151 PM EDT Tue Apr 2 2024

Messy convective systems continue to traverse Kentucky, with showers
and a few embedded thunderstorms still moving through LEX and RGA.
MVFR ceilings and southerly winds have re-established at SDF, BWG
and HNB.

Main question is when the atmosphere will reload sufficiently for
new convection over SW Indiana and western Kentucky, and what
impacts that will have later this afternoon. Will include TEMPO
groups for thunderstorms producing IFR vis from roughly 20-23Z, with
showers lingering into the evening. Look for gusts conservatively
near 30 kt with any storms, but could briefly be quite a bit higher
in any stronger storms.

Fropa this evening will shift winds to west, with MVFR cigs dropping
below 2000 ft. Gusts could lay down briefly well after dark, but
will pick back up to 20-25 kt with the quick onset of mixing in cold
advection Wed morning. Look for MVFR cigs to gradually lift into VFR
during the day.
