Short term (today and tonight)
issued at 310 am edt Tue sep 25 2018
Strong to severe storms possible this afternoon and tonight...
Significant flash flood threat continues for today and tonight...
mostly cloudy skies were found across the region this morning.
Surface analysis revealed an effective warm front bisecting the
region. Boundary was evidenced by dewpoints well in to the lower
70s in the i-65 corridor and points west, with a decrease in
dewpoints out toward the i-75 corridor. Nocturnal low-level jet was
starting to develop and on the nose of this jet we've seen some
showers go up this morning. Latest hrrr runs seem to be capturing
this fairly. Over the next few hours, mid-level perturbation over s
mo will lift northward into southern il in. We expect to see a bit
more convection develop across north-central and east-central ky
over the next few hours. The area at most risk for convection would
be areas along and north of the wk and bg parkways. Short term
trends in temperatures support readings remaining in the upper 60s
to the lower 70s.
Moving into the daylight hours, we should see aforementioned band of
convection steadily move northward into southern in later this
morning, with somewhat of a drier period of weather from mid-late
morning. Could see some breaks in the cloudiness as we get further
into the warm sector. However, current thinking is that much of the
area will likely remain mostly cloudy. Temperatures this afternoon
have a shot of warming into the upper 70s to the lower 80s in many
areas. Instability will increase this afternoon and scattered
thunderstorms are expected to develop. Overall severity of the
storms will be dependent on how much instability is available.
While there is a risk of severe weather this afternoon with gusty
winds and lightning being the main threats, heavy rainfall from the
storms is a very real concern. Antecedent soil conditions are just
saturated in many areas. Therefore any heavy rainfall will likely
result in flash flooding.
Tonight, the front to the northwest will move into the region. All
model guidance shows another line of convection accompanying this
front as it swings through. The front will be pushing through at
the nocturnal instability minimum, but any strong storm will be be
capable of producing damaging winds. Again, while severe focus is
there, the heavy rain aspect of this system will likely lead to
additional flash flooding tonight. Therefore, will keep the flash
flood watch going with this forecast. Overnight lows will range
from the lower 60s in our northwest areas to the lower 70s across
much of kentucky.
Long term (Wednesday through Monday)
issued at 255 am edt Tue sep 25 2018
by 12z Wednesday morning, the surface cold front is forecast to be
near a dayton to louisville to hopkinsville line. The new 25.00z run
of the GFS is quicker than most other models and thus, drier on
Wednesday. There's good consensus in holding on to|
likely categorical pops Wednesday morning from the bluegrass region
down through the lake cumberland region. Pops drop to the chance
category along the i-65 corridor, with a dry forecast in southwest
indiana. Isolated storms may persist into Wednesday morning east of
i-65, along with localized heavy rainfall. But areal-average QPF is
an additional 0.10-0.25 inches of rain between 12-18z. However,
significant flooding may be ongoing Wednesday from heavy rains the
night before. Flooding or continuing rain showers may impact your
Wednesday morning commute.
The front sweeps through during the afternoon, with showers
lingering mainly closer to the i-75 corridor. Winds will become
breezy out of the northwest, and temperatures won't make it out of
the upper 60s to lower 70s.
The primary upper trough over the great lakes quickly ejects
northeast Wednesday night as yet another wave moves over the
southern plains. This shortwave swings through the lower ohio valley
on Thursday, but the bulk of the moisture should be south of the tn
border. Still, a few showers could occur in the lake cumberland
region. Most places will see morning lows in the low to mid 50s
Thursday morning. A few low lying areas could even hit the upper 40s
in the northern bluegrass or southern indiana. Skies look partly
cloudy with highs Thu afternoon around 70.
Quiet weather will continue Thu night and Friday. Morning lows will
again be cool, down in the 50s. But with a bit more sun, afternoon
highs should be able to reach the mid 70s. A weak frontal boundary
is forecast to drop south toward the region this weekend, but it may
not have much moisture to work with. There's a low chance for
showers Friday night and Saturday. The better chance for widespread
rain will hold off until next Monday night and Tuesday. Highs this
weekend should end up in the 70s, pushing 80 in spots.
Aviation (12z TAF issuance)
issued at 640 am edt Tue sep 25 2018
nocturnal low level jet and isentropic lift will result in scattered
rain showers across the region this morning. Best widespread rain
chances would be over at klex during the first few hours of the taf
period and then we should see a bit of a break by mid-late morning.
However, during the afternoon hours we'll see convection refire.
Overall convective evolution is a bit uncertain and therefore will
keep vcts in the forecast at the terminals. Southwest winds will be
gusty today with speeds of 10-13kts and gusts of 20-25kts at times.
Cold front will approach the region tonight and a band of showers
and storms will likely accompany it as it comes through. The front
will likely clear khnb overnight but it will be Wednesday morning
before the front clears ksdf kbwg klex.
