KEY MESSAGES

* Dry weather and seasonable temperatures from a strong surface high are expected today through the end of the week.

* General showers and storm chances increase this weekend along with highs in the upper 80s.

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 /00Z TAFS THROUGH 06Z WEDNESDAY/

Issued at 1256 AM EDT Tue Jun 2 2026

VFR conditions will continue through this TAF cycle. Light sprinkles are noted over central Kentucky at this hour and will work south through the remainder of the overnight period. High pressure will work into the region from the north, which will help to clear skies by mid-morning. Ample mixing and an increased pressure gradient ahead of the high pressure will allow for breezy northeasterly winds. In the afternoon, we will see gusts 19-24kts. Wind gusts will subside with sunset this evening.
