DISCUSSION

Issued at 303 AM EST Fri Nov 13 2026

Today and Tonight...

A cold front passed through the region last night and brought a reinforcing shot of cold air advection. Overcast clouds are moving south at this hour and are expected to blanket the region this morning. Deep troughing will remain over the region today and continuous vorticity lobes will move in from the north in the morning, which will promote lift and bring additional moisture. Ongoing drizzle and light rain over southern Ohio will continue to work south and approach the Bluegrass region in the early morning hours. By late morning, widely scattered rain showers will move in from central Indiana. The main precipitation type will be rain, however, if we see a heavier downpour, we could see rain/snow mix or graupel. This is due to lower freezing levels (around 2000-3000ft), steep lapse rates, and cooler temperatures within showers. Otherwise, the tight pressure gradient will keep breezy NW winds around 10-15mph today.

Showers are expected to push southeast in the evening hours, as the upper troughing and energy begin to push east. We will see clearing skies from NW to SE overnight. The pressure gradient will begin to weaken, therefore, winds will become light overnight. Given these conditions, low temperatures on Saturday morning will be in the mid- upper 20s across most of the area, with urban areas in the low 30s.

Saturday - Mid Next Week...

Deep troughing will continue to push off to the northeast on Saturday. Strong surface high pressure will build in from the northwest and strengthen through the weekend. This will allow for drier and clearer conditions. Though, continued fetch off of Lake Michigan may keep some clouds over southern Indiana and northern Kentucky through part of Saturday.

Building ridging will allow heights to increase each day through mid next week. Therefore, high temperatures will increase 4-5 degrees each day, reaching the 60s by mid week. Dry conditions, calm winds, and clear skies will allow overnight temperatures to remain in the 20s and 30s through most of this long term period. Mid next week, ample mixing and warmer afternoon temperatures may bring minimum afternoon RH into the 20-30% range.

AVIATION /18Z TAFS THROUGH 00Z SUNDAY/

Issued at 1229 PM EST Fri Nov 13 2026

Scattered showers will continue to pass over the airfields through the afternoon, producing sporadic visibility reductions into the MVFR category. Meanwhile, ceilings will gradually climb from around FL015 to FL035, eventually breaking up and shifting south of the terminals by evening. Northwest winds of 7-11 kt will ease this evening, possibly (15-30% chance) allowing patchy fog to develop mainly at HNB and/or RGA during the 09-13z timeframe.
