.SHORT TERM /THROUGH TONIGHT/...
Issued at 250 AM EDT Mon Apr 6 2026

Seeing a clear, cold, and quiet night across the CWA. There is a
thin shield of upper sky cover skirting southern KY, otherwise
everyone else has clear and calm conditions promoting excellent
radiational cooling. Plan to leave the Frost Advisory as is for the
NE half of the CWA, although not overly confident about the SW half
of it where temps are currently sitting in the 40 to 45 degree range
in most spots. Could still have some decoupled sheltered areas, so
will re-evaluate around 430-500 AM and decide whether to trim some
of it in the SW CWA.

Otherwise, look for a dry and quiet day with mostly sunny skies and
temperatures climbing to near normal values in the low and mid 60s
for most. Some upper 60s to near 70 are possible down across
southern KY. A dry cold front does approach and pass later today, so
surface winds will veer around from SW to W, and then a bit gusty
out of the WNW through the afternoon.

Another cold night expected tonight with most low temperatures
ranging in the 35 to 40 degree range. Some colder temperatures are
expected in the decoupled valleys, especially in our NE CWA where
some low 30s are likely in spots. Could see another round of
potential frost later tonight, but the the big limiting factor will
be surface winds up in the 5-10 mph range, and perhaps some variable
mid level cloudiness as well. There has been a consistent signal for
frost potential across our NE third of the CWA, and would expect if
any headlines are needed later today, that is where it would be
placed. A few sheltered areas could see freezing temps, but not
expected that to be widespread unless surface winds were lighter
than anticipated.

.LONG TERM /TUESDAY THROUGH SUNDAY/...
Issued at 250 AM EDT Mon Apr 6 2026

Tuesday - Tuesday Night...

Strong Canadian high pressure traverses the Great Lakes region
Tuesday and Tuesday night, with fairly steady N to NE surface winds
in place across our area. This cold advection component combined
with some variable mid level cloudiness from an upstream band of
precipitation will act to keep temps well below normal. Only
expecting highs in the low to mid 50s across southern IN and north
central KY. Expect to still squeak out highs in the low 60s across
southern KY. Going into Tuesday night, still expect a decent
pressure gradient over the area, along with a few mid clouds.
Sheltered valleys likely decouple into the lower 30s, however most
everyone else expected to be in the mid to upper 30s. Frost is a
question mark for Wednesday AM as the surface winds and cloud cover
lower confidence in just how much we could see. Right now, the
Bluegrass region looks to be the most favorable for frost, or even a
light freeze in some of the sheltered valleys.

Wednesday - Thursday Night...

Our dry stretch continues thorugh mid week with a trend back toward
milder temperatures by this time. Surface high pressure that had
been centered to our north will shift eastward and allow some return
flow across the area. We`ll keep partly to mostly sunny skies in
place as well which should allow for warming temps back above
normal. Highs on Wednesday peak in the upper 60s and low 70s, with
Thursday highs back in the low to mid 70s. Both Wednesday and
Thursday nights will also be notably milder thanks to the southerly
return flow.

Friday - Sunday...

Will be keeping a mostly dry forecast in place for the late week and
into the weekend, however will have to keep at least some small
chances for a shower or storm in across our northern CWA for Friday
and Friday night as a weak frontal boundary sags toward our area.
This feature is expected to stall as it encounters a building upper
ridge over the SE CONUS, and exactly where that occurs will
determine whether we keep those low chance pops, or end up with our
fully dry trend continuing, because the front should lift back to
the north by Saturday and Sunday. This will result in even milder
temperatures with a continued dry forecast. After highs in the mid
to upper 70s on Friday, look for upper 70s and low 80s on Saturday,
and low to mid 80s by Sunday.

.AVIATION /06Z TAFS THROUGH 12Z TUESDAY/...
Issued at 126 AM EDT Mon Apr 6 2026

VFR prevails through this forecast cycle with high pressure to our
west gaining control over the region. Expect very light to calm
winds early this morning, before steady W, and then gusty WNW winds
take hold late morning through the afternoon. Could see a few cu
around 5-6K feet for a few hours this afternoon, but overall look
for mostly sunny skies. Winds slacken early evening and maintain a
light NW component into later tonight.
