.UPDATE... Issued at 1018 AM EDT SUN SEP 7 2025
Fog has lifted into a low stratus deck which is now rapidly eroding. Therefore, the Dense Fog Advisory was allowed to expire at 10 AM. We are still on track to have a mostly sunny afternoon with cool high temperatures in the lower to middle 70s.
UPDATE Issued at 740 AM EDT SUN SEP 7 2025
Fog, locally dense, persists across much of eastern Kentucky, though it has lifted into a low stratus deck over the deeper river valleys. The stratus and fog should continue lifting and thinning out over the next couple of hours, leaving behind mostly sunny skies and a developing fair weather cumulus field. Hourly T/Td forecast has been brought into line with recent observations; and the sky cover was increased slightly, primarily this afternoon, to account for the anticipated extensive cumulus field. Otherwise, current forecast is on track.

.SHORT TERM...(Today through Monday) Issued at 442 AM EDT SUN SEP 7 2025
The latest surface analysis shows a strong dome of high pressure centered over the Buffalo Ridge in southwestern Minnesota. The high- pressure domes influence can be felt here in eastern Kentucky, as clear skies and dry weather are present. However, widespread dense fog has developed due to clear skies and an abundance of moisture remaining from yesterdays rain. Due to the widespread dense fog, the entire area was placed under a Dense Fog Advisory through 10 AM this morning.
A surface high-pressure system will remain overhead through the entire forecast period, which will lead to dry weather. Upper-level northwesterly flow will advect below-average temperatures into the region today and Monday. Temperatures today will climb into the mid- 70s and into the upper 70s for Monday. Overnight lows will be cooler, with lows falling into the low to upper 40s. Clear skies overnight will allow the more sheltered valleys to possibly get a few degrees colder.
.LONG TERM...(Monday night through Saturday) Issued at 442 AM EDT SUN SEP 7 2025
A surface high-pressure system will remain in place throughout the long-term forecast period. Dry weather will accompany this surface high pressure. Temperatures will begin to warm as flow shifts to a west-southwesterly direction. Those temperatures will climb back into more seasonal averages for the remainder of the forecast period.
The period will be dominated by a surface high-pressure system. Dry weather is to be expected. Temperatures will begin to warm into the 80s for the entire period, with overnight lows falling into the upper 40s in the more sheltered valleys but largely into the 50s and low 60s elsewhere.

.AVIATION...(For the 12Z TAFS through 12Z Monday morning) ISSUED AT 657 AM EDT SUN SEP 7 2025
IFR TAFs are occurring with this TAF issuance. These conditions will persist over the next couple of hours until fog burns off. VFR conditions are expected after 14Z and will remain VFR through the remainder of the period. Winds will be light and variable through the TAF window.

.JKL WATCHES/WARNINGS/ADVISORIES... None.
