.SHORT TERM /THROUGH TONIGHT/...
Issued at 308 AM EDT Tue Jun 2 2026

Troughing will continue to swing through the region this morning,
which has allowed for some broken mid level clouds to push in from
the north. By mid-morning, these clouds will thin and exit to the
south. We are also seeing some areas of fog in the Lake Cumberland
region. This fog will lift within a few hours of sunrise.

High pressure will move south into the Ohio Valley from southern
Canada today and tonight. Aloft, ridging will slowly build east and
increase heights. Conditions today and tonight will feature dry
weather, highs in the upper 70s and low 80s, low RH, and breezy
northeasterly winds up to 25mph in the afternoon. Tonight,
temperatures will dip into the mid-upper 50s.

Given ample mixing and ensemble probabilities, did lower dew points
for this afternoon a bit. This will bring minimum relative humidity
this afternoon into the 28-33% range.

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Issued at 308 AM EDT Tue Jun 2 2026

Ridging aloft will continue to build into the region and strong high
pressure will remain at the surface. This will keep dry conditions
over the region through the end of the week. Temperatures will warm
each day into the mid-upper 80s. With ample mixing and unseasonably
dry PWATs, expect dry RH in the 28-33% range each day.

This weekend, our dry streak will likely end as a closed low moves
east through the Ohio Valley and brings a surface low pressure
system with it. Current timing of this system is late Saturday
through Sunday. The front associated with this system is expected to
stall within the Ohio Valley, which will keep precip chances in the
area through early next week. Current QPF is light under 0.5 inches
for this system. Severe weather chances look limited at this time.

.AVIATION /18Z TAFS THROUGH 00Z THURSDAY/...
Issued at 152 PM EDT Tue Jun 2 2026

VFR conditions continue due to a very dry airmass drifting in from
the northeast. Northeast sfc winds will continue through the
forecast period, with winds and gusts gradually diminishing after
23Z this evening. Northeast winds of 10-12 kts with gusts to around
20 kts will continue through 23Z.
