643 FXUS61 KILN 201817 AFDILN Area Forecast Discussion National Weather Service Wilmington OH 117 PM EST Thu Nov 20 2025 .SYNOPSIS... High pressure will move off to the east, although clouds will be stubborn. Rain will spread back into the area late tonight and continue into Friday night as an area of low pressure moves through the region. High pressure will build in for the weekend. && .NEAR TERM /THROUGH TONIGHT/... Beyond the improvement in low level visibility, there has been very little change in current conditions throughout the first part of the day. The local area is currently on the western side of a high pressure that is sliding off to the east. Cloud cover associated with the low- level inversion continues to hold strong, but across portions of central Kentucky, there are few signs of the moisture becoming shallow enough for clouds to break up. However, with a weak system moving to the south of the region this afternoon, mid and upper level clouds thicken, preventing more efficient mixing/drying. The best chance for low-level clouds to clear is across northern Kentucky and southern Ohio. Given all of the cloud cover, temperatures are struggling to warm with the only chance of reaching the 50s being across the far south in northern Kentucky and southern Ohio. The weak system to the south is spreading some light rainfall into the tri-state and northern Kentucky, but will remain limited until better support arrives overnight and into Friday morning. As moisture increases, fog will once again develop late this evening and continue into the morning. Persistence forecasting would suggest the possibility of dense fog conditions is once again possible through the overnight and into Friday morning. && .SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/... Current expectations are for periods of light rain to increase in coverage across the area throughout the morning hours as the warm front lifts northward and deeper moisture returns. A trough entering the Great Lakes region will act as a suppressant to the northward progress, perhaps limiting the northward extent of the better rainfall. With this in mind, the HWO wording for the locally heavy rainfall remains focused on the southern half of the area. The entire area should expect another day of overcast skies with areas of fog in the morning. This will continue until the trough and low pressure shift out of the area late Friday night into Saturday morning. All in all, rainfall amounts will range from 0.25" to 0.50" with locally higher amounts up to 1" by the time the rain concludes. Forecast high temperatures may once again be too aggressive with the higher values, but depending on the track of the low pressure, upper 50s to lower 60s are possible in the southern portions of the area. && .LONG TERM /SATURDAY THROUGH THURSDAY/... Rain will be tapering off Saturday morning across southeastern portions of the region. Dry conditions are then expected Saturday afternoon through Monday morning. There is still a spread in timing with the next system. While there might be some rain chances Monday into Monday night the most widespread and heaviest precipitation is expected to be Tuesday into Tuesday night. There will be some lingering precipitation on Wednesday. There is also a low potential for some precipitation as well on Thursday. Confidence is not as high during these time periods and there is more variability on cold air on if there will be a wintry element to it. At this time however, most of this time frame is expected to be have precipitation in the form of rain when precipitation is occurring. There will also be breezy conditions with the system Tuesday into Wednesday. A cooler airmass will be in place by the end of the long term. && .AVIATION /18Z THURSDAY THROUGH TUESDAY/... Pessimistic aviation outlooks continue over the next 36 hours as moisture lingers in the region with another system approaching. For the immediate time period (next 6 hours), slight improvement in cloud heights are expected, perhaps out of IFR. Across central Kentucky, there some sign of improvement, and enough confidence was in place to provide a brief break in the restrictions across CVG/LUK late this afternoon and early evening. Trends will continue to be monitored over the next couple of hours. Otherwise, the entire period is covered by IFR/LIFR CIGs and MVFR/IFR VIS with the next system ushering in another round of deeper moisture. Chances for rain also increase into the morning and afternoon hours as the warm front and low pressure move northward. Precipitation does not clear until late Friday night or Saturday morning with aviation improvements finally arriving during the day on Saturday. Winds are light and out of the south today, but will go weak and variable tomorrow as the low pressure slides along the Ohio River region. OUTLOOK...IFR/LIFR ceilings with MVFR/IFR visibilities into Friday night. MVFR ceilings may persist into Saturday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None.
