.KEY MESSAGES...
* Heat Advisory continues through this evening.
* Chances for mainly afternoon/evening showers and storms each day
through Tuesday.
* Less humid conditions arrive next Wednesday and Thursday.
&&
.SHORT TERM /THROUGH TONIGHT/...
Issued at 333 AM EDT Fri Jun 27 2025
Slightly weakened upper ridge remains draped east to west across the
Ohio Valley. Hot and humid air mass remains in place in the low
levels, and we`ll have fairly similar conditions to Thursday,
perhaps with a bit less convective coverage. Still looks like
scattered afternoon thunderstorms, and while shear is too weak to
support organized severe wx, there is plenty of instability for your
typical pulse storm hazards, i.e. gusty or locally damaging winds
and torrential rainfall.
Heat Advisory carries on for one more day, as temps will rise
quickly this morning and crack 90 in many locations before noon.
There is a sufficient window of opportunity for 100+ heat index
values before convective outflow can provide any relief.
Any storms should fade fairly quickly around sunset, leaving behind
another warm and muggy night. Will hang on to a 20 POP in quite a
few spots just because of the tendency for such a juicy air mass to
spark an isolated nighttime storm or two.
&&
.LONG TERM /SATURDAY THROUGH THURSDAY/...
Issued at 333 AM EDT Fri Jun 27 2025
Unsettled pattern this weekend into early next week with weak zonal
flow aloft and a juicy low-level air mass in place, supporting
mostly diurnally driven thunderstorms each day.
On Saturday, an upper shortwave trof moving east across the Great
Lakes will push a cold front toward the Ohio Valley, but the
boundary will hang up across Illinois and Indiana. Scattered to
numerous showers and storms are possible, but will be mostly garden-
variety convection as shear is too weak to support severe wx, and
the better focus for training and heavy rainfall will be to our
north. Could still see a stray pulse storm that would be capable of
producing gusty, locally damaging winds.
Another peak in precip chances will come Monday and Tuesday as a
sharper upper trof finally drives a cold front solidly into the Ohio
Valley. Expect widespread showers and storms with that system, with
severe risk limited to pulse storm hazards as the stronger wind
fields remain to our north.
Latter half of next week will feature a low-amplitude upper trof
over the Great Lakes and eastern Canada, with NW flow over the Upper
Midwest helping to build a bubble of sfc high pressure into the Ohio
Valley. Wednesday through Friday will have near-normal temperatures,
but manageable dewpoints in the lower to mid 60s. Precip chances
will be limited to isolated diurnal pop-ups, mainly across southern
Kentucky but starting to expand northward on Independence Day.
&&
.AVIATION /12Z TAFS THROUGH 18Z SATURDAY/...
Issued at 635 AM EDT Fri Jun 27 2025
Main challenge is timing and impact of scattered thunderstorms this
afternoon and evening, assuming they actually impact each of the
terminals. Brief IFR vis possible with the heaviest rain, but figure
3SM is the lowest that will stick around for any length of time. CB
bases won`t be very low, most likely 3-4K feet. Given the hit-and-
miss nature of expected convection, will handle it with a PROB30
focused mainly on the 20Z to 02Z Sat time frame.
Otherwise expect prevailing VFR conditions with SW winds around 10
kt during the mixy part of the day, diminishing and backing to due
south again once the sun sets.
