AREA FORECAST DISCUSSION
National Weather Service Jackson KY
325 PM EDT Thu Apr 25 2024

.KEY MESSAGES...

- Frost is possible in some valleys again tonight.

- A warming trend begins on Friday, with well above normal
  temperatures then expected early next week.

- There is a small potential for showers in association with a
  warm front Friday and/or Friday night. There is a better chance
  at showers and thunderstorms as we move into the new work week
  due to the approach of a dying cold front.

.SHORT TERM...(This evening through Friday night)
Issued at 325 PM EDT THU APR 25 2024

Surface high pressure centered over far southeastern Ontario late
today will move east over New England tonight, providing us with
continued fair weather in a cool and dry air mass. Aloft, ridging
will arrive from west tonight, getting squeezed between a slowly
departing trough to the east and a storm system impinging on the
ridge from the west. High clouds associated with warm air
advection may begin to spill through the ridge tonight, but will
probably be insufficient to have much impact on temperatures.
Considering the dryness of the air mass, it would appear that our
northern valleys will again be marginally cold enough for some
frost by morning.

The aforementioned storm system will slowly move from the central
plains to the upper Midwest on Friday and Friday night as surface
high pressure and ridging aloft shift slowly away to our east. This
will result in increasing warm air advection for the local area
ahead of a warm front. This front currently lies from the central
plains to the FL panhandle. It will approach us on Friday and arrive
Friday night, but will become ill-defined as it arrives, with the
greatest push of warmer air being to our north and northwest. Models
have not been consistent on the prospects of precip for our area
with this front, and have been focusing the greatest POP to our
northwest and north in the stronger warm air advection. In the
uncertainty, will continue to carry low POPs in the forecast Friday
and Friday night, along with an increase in clouds. Despite the
clouds and possible precip, warm air advection should result in
higher temps on Friday, with clouds then also helping to hold
readings higher on Friday night.

.LONG TERM...(Saturday through Thursday)
Issued at 325 PM EDT THU APR 25 2024

An updated long term discussion will be sent shortly.

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)

southeast KY overnight and early Friday morning, but should not
affect TAF sites.
