AREA FORECAST DISCUSSION
National Weather Service Jackson KY
327 PM EDT Sun May 12 2024
.KEY MESSAGES...
- Precipitation free weather reigns through Monday morning, before
an approaching system from the Plains brings more unsettled
conditions.
- Near to a little above normal temperatures this work week.
&&
.SHORT TERM...(This evening through Monday night)
Issued at 316 PM EDT SUN MAY 12 2024
High pressure at the surface and aloft making for a beautiful Sunday
across eastern KY. The surface high will shift east of the region
tonight, allowing for a southerly wind flow to start. This shift
should allow for a quick warm up. We'll start the day Monday right
around normal, with our valley locations dropping into the mid to
upper 40s. Highs Monday likely around warm to about 5 degrees warmer
than today.
A southwest flow aloft Monday afternoon will allow for moisture to
get pumped into the region, bringing a return to rain and storm
chances by late afternoon and through the night. Given that today is
fairly dry across the region, this moisture return won't be strong
enough to bring heavy rains in the short term. Better rains look to
hold of to Tue/Wed time frame.
.LONG TERM...(Tuesday through Sunday)
Issued at 327 PM EDT SUN MAY 12 2024
An active week of weather on tap in the extended. The general model
consensus suggests that a series of weather systems will move across
the eastern half of the CONUS from Tuesday onward. There should be
one breif lull in the action Wednesday night and Thursday, as one
system exits to our east, and a weak ridge of high pressure aloft
moves through behind the exiting trough. The ridge will be somewhat
flat, and may extend from the Gulf of Mexico only as far north as
the lower Ohio Valley. The ridge will be quickly displaced Thursday
night, as another large trough of low pressure moves in from the
Great Plains. The first cyclone will bring widespread showers and
storms to eastern Kentucky Tuesday through Wednesday. Showers and
storms will be most prevalent during the afternoon and evening
hours, when heating and instability will be maximized. This scenario
will repeat itself Thursday night into Saturday, as a second low
pressure system move through. Used a blend of the latest runs of the
GFS, GFS Ensembles, and ECMWF models to formulate the extended
portion of the forecast this time around.
Temperatures should be near normal to begin the period, but will
steadily increase through out the week, as persistent southerly and
southwesterly flow sets up across the region. We could easily see
highs reaching the upper 70s and lower 80s by the end of the week
across eastern Kentucky. Forecast concerns will include cloud to
ground lighting that occurs with any thunderstorms and locally heavy
rainfall with any storms. We are not expecting any hydro issues or
severe weather across eastern Kentucky in the extended at this
time.

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
ISSUED AT 1257 PM EDT SUN MAY 12 2024
Tranquil flying conditions for this forecast period. Winds
generally will be light and variable. Winds will start picking up
from the south early Monday afternoon. Otherwise, Monday morning
could see some patchy valley fog, but the terminals should stay
VFR.
