494 FXUS63 KJKL 201119 AFDJKL AREA FORECAST DISCUSSION National Weather Service Jackson KY 619 AM EST Thu Nov 20 2025 .KEY MESSAGES... - Low clouds and drizzle are likely to linger into the afternoon across much of eastern and northeastern Kentucky today. - Active weather continues through the end of the work week, with a seasonably mild and moist airmass in place. - Another system will bring rain to the area late Monday into the middle of next week. - A strong cold front is expected at the end of the period, on or around Thanksgiving Day, and is likely to bring much lower temperatures to eastern Kentucky to end next week. && .UPDATE... Issued at 531 AM EST THU NOV 20 2025 Pre-dawn update is out with not much in the way of change to the forecast. Hourly temperatures were updated by using the latest observations as the initialization and then interpolating into the morning package hourly temperature forecast. && .SHORT TERM...(Today through Friday) Issued at 233 AM EST THU NOV 20 2025 Stratus is likely to remain across much of eastern and northeastern Kentucky today as warm and dry mid-level air remains above a relatively shallow cool and humid layer trapped near the surface. This pattern will break down later today, as the mid- levels will moisten with the approach of an ejecting disturbance from a large upper low over the southwestern CONUS and northwestern Mexico. This will also allow for the stationary front over the Tennessee Valley to begin moving north as a warm front by Friday. Given NBM guidance has been way too warm across the CWA the last couple of days, especially the northern and northeastern parts of the forecast area, we have thus lowered temperatures once again for today, with temperatures remaining fairly steady through the overnight tonight across the north as weak warm advection counters the typical diurnal temperature trend. Extensive cloud cover will across the region from the west later today into tonight, with rain overspreading the region to the north and northeast of the stationary/warm front during the afternoon and evening hours. Increasing instability, though weak, will move into the region with the passage of the warm front Friday, allowing for the chance for some heavier showers and some thunderstorm activity for the second half of the day. However, no significant flooding concerns are expected with total QPF with this upcoming system still in the 0.6 to 1.2 inch range. .LONG TERM...(Friday night through Wednesday) Issued at 233 AM EST THU NOV 20 2025 The period begins Friday night with the area within the warm sector of an approaching mid-level disturbance and cold front. Thus, high PoPs are expected until cold frontal passage Saturday morning, with decreasing PoPs favoring the typical cold advection upslope areas across southeastern Kentucky Saturday afternoon. Saturday night through the first half of Monday, the NBM has begun trending cooler as models and their ensemble systems have come into better agreement that this period will see relatively dry conditions with decreased cloud cover and light winds. The next system arrives late Monday into Tuesday with fairly high confidence, though there are discrepancies in the depiction of the evolution of the mid-level pattern between the models, especially heading into the middle of next week and the busiest part of the holiday travel period. Thus, PoPs have been raised by around 20 percent on average compared to previous package from Monday night through Tuesday night, with considerable uncertainty remaining for Wednesday into Wednesday night based on if the upper trough and surface front completely clear the area to the east or if they linger back far enough west over the Ohio Valley for another round of light precipitation before clearing the area. A much cooler, if not downright cold, pattern appears likely behind the expected cold front passage at the very end of the long-term period or just beyond beginning next Thursday, so these trends will continue to be monitored over the coming days. && .AVIATION...(For the 12Z TAFS through 12Z Friday morning) ISSUED AT 619 AM EST THU NOV 20 2025 Poor conditions are forecast into the day Thursday-- generally IFR or worse. Improvement to VFR is possible for a time late in the day or in the evening. However, showers and deteriorating conditions are forecast to arrive again from the west by the end of the period. && .JKL WATCHES/WARNINGS/ADVISORIES... None. && $$ UPDATE...CMC SHORT TERM...CMC LONG TERM...CMC AVIATION...CMC/HAL
