.UPDATE... Issued at 200 PM EDT SAT SEP 6 2025
Anafrontal stratiform precipitation shield continues to slowly push southeast this afternoon. The back edge of the rain extends from near Flemingsburg southwest to Bowling Green at 18Z. This activity will continue sagging southeast through the remainder of the afternoon. However, guidance does suggest that PoPs will tend to linger deep into the evening near and southeast of the Hal Rogers/KY-80 corridor.
UPDATE Issued at 1009 AM EDT SAT SEP 6 2025
Light rainfall will continue to spread east across the remainder of far eastern Kentucky late this morning and is should linger through much of the afternoon as a cold front slowly moves through our region. Temperatures are running below guidance and are expected to only reach the middle to upper 60s for most locations. Forecast has been refreshed with latest high-res model trends and hourly observations.

.SHORT TERM...(Today through Sunday) Issued at 446 AM EDT SAT SEP 6 2025
The latest surface analysis shows a cold front oriented northeast to southwest through the northwestern portion of the CWA. This boundary is tied to an occluding surface low centered over the southern Hudson Bay region. Early this morning, showers and a few isolated thunderstorms are moving across the CWA ahead of the approaching cold front.
Throughout the remainder of the morning into the afternoon, showers and thunderstorms are expected to redevelop ahead of the cold front. These will persist through the mid-afternoon before the cold front crosses through the forecast area and exits later this evening. The severe weather threat for today is almost nonexistent, but a stronger storm or two cannot be ruled out across the far southeastern portions of the area. The biggest threat today will be the potential for additional and persistent heavy rainfall. Fortunately, the precipitation will be progressive, and the threat of hydrological issues will be minimal.
Behind the exiting front, surface high pressure will begin to build into the region from the northwest and remain overhead through the remainder of the forecast period.
The period will be highlighted by the passage of a strong cold front that will bring showers and storms. Surface high pressure will slowly build into the region behind the exiting front this afternoon. Temperatures will be much cooler today, with highs only reaching the upper 60s to low 70s, but will rebound slightly on Sunday as highs climb into the mid-70s. Due to expected clear skies, overnight temperatures will consistently fall into the low to upper 40s.
.LONG TERM...(Sunday night through Friday) Issued at 446 AM EDT SAT SEP 6 2025
Surface high pressure will remain largely in place throughout the long-term forecast period. Dry weather will accompany this surface high pressure, and temperature swings will be the major highlight of the forecast. Post-frontal CAA will continue to keep cooler temperatures in the forecast through early next week. However, as flow begins to shift to a west-southwesterly direction, temperatures will begin to climb back into more seasonal averages for the remainder of the forecast period. In the overnight model guidance, models are hinting at the possibility of a dry cold front Thursday into Friday. Due to a lack of moisture, the front will be dry, but a temperature drop is expected on Friday.
The period will be dominated by surface high pressure. Dry weather is to be expected. Temperatures will be slightly below normal, with highs in the mid to upper 70s and overnight lows in the upper 40s to mid-50s, before beginning to warm for the start of the work week.

.AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon) ISSUED AT 200 PM EDT SAT SEP 6 2025
A range of VFR to IFR conditions in light to briefly moderate rain are noted across eastern Kentucky at the 18Z TAF issuance, courtesy a slow-moving cold front. Rainfall will gradually diminish from northwest to southeast between 19Z and ~0-3Z. Temporary improvement in ceilings can be expected but widespread post-frontal stratus and low fog is likely to form overnight with widespread IFR or worse conditions developing. Winds will be variable to northwesterly, generally around 5 kts or less.
