Area Forecast Discussion
National Weather Service Louisville KY
639 AM EDT Wed May 5 2021

...Updated Aviation Discussion...

.Short Term...(Today and tonight)
Issued at 250 AM EDT Wed May 5 2021

After an active period of weather, things are finally starting to
quiet down across the OH Valley. Current radar imagery shows
precipitation tapering off from west to east, with most of the rain
pushing east of I-65 at this hour. Surface observations reveal
temperatures in the upper 50s to mid 60s with the warmer temps
across eastern portions of the area closer to the surface front.
Winds have shifted to the northwest across much of the area at
around 5-10 mph and occasional gusts to 20 mph have been observed.

Moving through the early morning hours, expect rain to exit the area
around or shortly after sunrise. Low clouds will persist in the wake
of precip, but should then gradually clear from west to east
throughout the morning and into the early afternoon. Under steady NW
flow and CAA, highs for the day will remain about 5-10 degrees below
climatological normals, topping out in the lower to mid 60s.
Increasing mid-level clouds will begin streaming in late tonight
ahead of an approaching shortwave. Overnight temps will bottom out
in the lower 40s with some spots dropping into the upper 30s.

.Long Term...(Thursday through Tuesday)
Issued at 300 AM EDT Wed May 5 2021

Thursday - Friday...

The upper pattern at the end of the work week will feature a NE
CONUS trough, and west central CONUS ridging. Within the parent
trough, two separate shortwaves will rotate through the region. The
first will bring a chance for scattered showers and a few rumbles of
thunder later Thursday into Thursday evening, and the second is
expected to graze mainly the Bluegrass region on Friday with some
isolated to widely scattered showers and perhaps a storm. Take a
look at a sounding in the Bluegrass for Friday afternoon and you
will see very steep low and mid level lapse rates. The freezing
level would likely be around 5 K feet with plenty of instability
above this layer sufficient for hail. In addition, the sounding
looks as if it could produce notable gusty wind potential. Would not
be surprised to see hail or gusty winds with any storm in the
Bluegrass on Friday afternoon. Below normal temps in the low to mid
60s are expected each afternoon. Lows Thursday night will be chilly
in the low to mid 40s. Perhaps even a few upper 30s will be possible
in the coolest spots.

Friday Night...

Should see a brief dry period over our area Friday night as benign
NW flow aloft holds over the area, and no notable forcing/deep
moisture will be around. A sizable temp gradient is possible for
overnight lows as a warm front begins to impede on the area. Low 40s
in our NE, and lows near 50 in our SW are expected.

Saturday - Sunday Night...

The main focus for the long term is expected to set up on Saturday
and last through the weekend. The NW flow aloft will transition to a
more zonal flow, with lee cyclogenesis quickly ejecting out of the
high Plains and into the mid Mississippi River Valley by Sunday
morning. This feature is then expected to move through the Ohio
River Valley on Sunday and to the mid Atlantic coast by Sunday
night.

On Saturday, a warm front will set up over our area ahead of the
developing/ejecting surface low, with isentropic lift bringing
increased chances for showers and a few storms focusing across
southern IN and northern KY by Saturday night. The most widespread
rainfall and better chances for T-storms will arrive Sunday as the
low passes through the region. Depending on how much the warm sector
destabilizes, you do worry about the triple point of a surface low
moving through your CWA in early to mid May. Right now, it appears
that instability may be a bit lacking, but something to watch in the
coming days for both a heavy rain and potential strong to severe
storm threat. For now, the bigger concern appears to be widespread
rainfall amounts in the 2 to 3" range, with locally higher amounts
possible. These values combined with the recent heavy rainfall we've
had could cause some problems if they are realized. Temps in the
warm sector on Monday should reach the low to mid 70s across the
area.

Monday - Tuesday...

Confidence is fairly high in a dry period for the Monday/Monday
night time frame as brief shortwave ridging takes over the area.
Tuesday confidence is lower given uncertainty in the models, but a
another system could impact our region by then. Temps will run a bit
below normal in the upper 60s and low 70s for highs.

.Aviation...(12Z TAF Issuance)
Issued at 635 AM EDT Wed May 5 2021

IMPACTS:
- IFR/MVFR ceilings gradually lift into VFR this morning

DISCUSSION: Earlier morning showers have exited the area with dry
weather expected through the remainder of the TAF period. Ceilings
are generally in MVFR/IFR range at the moment, but satellite imagery
shows the clearing line is beginning to work its way into the area
with clouds expected to clear shortly at HNB. As ceilings continue
to lift through the morning, expect all sites to be VFR by this
afternoon with VFR conditions then prevailing through the end of the
period. Some mid- and high-level clouds may begin streaming into the
area late tonight ahead of an approaching system.

Winds will be out of the N/NW today at around 10 kts with occasional
gusts to 20 kts possible. Winds will then become light/variable
overnight and begin shifting around to the E/SE.
