KEY MESSAGES

* Dry weather expected through the end of the week, with afternoon highs in the low to mid 80s.

* Warmer and more humid this weekend into early next week. Gradually increasing shower and thunderstorm chances this weekend.

SHORT TERM /THROUGH WEDNESDAY NIGHT/

Issued at 330 PM EDT Tue Jun 2 2026

It's a beautiful afternoon across central Kentucky and southern Indiana. Skies are clear, and temperatures are hovering in the 75-80 degree range. Aloft, a ridge extends from the southern Plains northeast to the Upper Midwest. A sfc high is centered over the Great Lakes, with low level northeast flow advecting dry air into the Ohio Valley.

High pressure at the surface and aloft will slowly build southeast across the Ohio Valley through Wednesday night, bringing a stretch of fair weather. Northeast winds of 10-20 mph will diminish this evening with sunset. Early Wednesday looks mostly clear and calm, with lows in the low to mid 50s. Cannot rule out a couple upper 40s in our coolest sheltered spots. Wednesday will feature mostly sunny skies, a 5-10 mph east wind, and afternoon highs in the low 80s.

LONG TERM /THURSDAY THROUGH TUESDAY/

Issued at 330 PM EDT Tue Jun 2 2026

An upper level ridge will remain in place over the eastern CONUS on Thursday, with sfc high pressure shifting over the Appalachians. This will set us up for a warmer and dry end to the work week with the onset of low-level SW return flow. Expect mid 80s to be more common for highs, with overnight lows near normal (upper 50s and low 60s).

Ridging continues to shift over the Southeast US and offshore this weekend. Meanwhile, multiple mid-level shortwave disturbances are forecast to stream eastward across Canada and the northern US downstream of an amplifying upper level ridge. At the surface, weak low pressure appears likely to zip across southern Canada, with a trailing cold front gradually sliding south into the Ohio Valley. We'll see increasing moisture availability as this boundary approaches, with PW values increasing above 1 inch by Saturday and above 1.5 inches Sunday.

LREF members support a 20-30% chance for rain Saturday afternoon and evening, mainly across the northern forecast area. Scattered showers and storms look possible across the whole forecast area by Sunday and Monday. Expect warmer, more humid conditions this weekend into early next week. Highs in the mid/upper 80s should be common.

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.
