Area Forecast Discussion National Weather Service Paducah KY 509 AM CST Sun Nov 8 2026
KEY MESSAGES
- Widespread frost/freeze overnight tonight is expected to end the growing season. Patchy fog is also possible near bodies of water.
- Above normal temperatures are expected Monday through Wednesday with highs reaching the upper 60s to near 70 degrees. The warming trend may also lead to more widespread patchy fog Monday morning.
- Rain showers have increased to a 30-50% chance Wednesday afternoon into Wednesday evening as a cold blast filters into the region. Sprinkles linger into Thursday with breezy and chilly conditions, followed by a 40-60% chance of highs struggling to reach above 50 degrees on Friday.
DISCUSSION
Issued at 1209 AM PM CST Sun Nov 8 2026
Conditions ideal for radiational cooling are developing as expected across the area tonight. Some sites are already below freezing and those that aren't stand a very good chance of making it below by sunrise with a heavy killing frost. The freeze warning will remain in place til the morning and this should be the last one necessary for the year as the growing season should be definitively over by the time this back to back heavy frost period ends. Ground fog is possible with soil temperatures in the low 50s and residual warm water temperatures.
The next item of interest presents on Wednesday. The guidance suite is in considerably better agreement tonight on a fairly broad upper trough digging in from the northwest and spinning up a 1002-1004mb surface low that tracks across the northeastern quarter of the region as a strong cold front storms in behind.
Rainfall looks increasingly likely with amounts on deterministic and ensemble blends ranging from one-quarter to one-half inch.
The source airmass behind this front is in northern Canada where it is currently around -10F so this may be the first pseudo- arctic airmass of the cool season and Thursday and Friday at least look likely to be at least a little below seasonal norms.
To add to matters northwest winds 10-20 mph are shown by most available guidance and make sense given the synoptic situation, so it will feel even colder.
AVIATION /12Z TAFS THROUGH 12Z MONDAY/
Issued at 509 AM CST Sun Nov 8 2026
Ground fog/freezing and fog near warm bodies of water will remain a factor until after sunrise. At that point conditions should quickly improve to VFR. A light west wind picks up later this morning with winds becoming calm overnight. The outlook is for VFR conditions overnight although patchy fog will be watched as a possibility.
