KEY MESSAGES

- Warm conditions are expected today and continue into Wednesday ahead of a cold front that will reach eastern Kentucky Wednesday night.

- This cold front will bring widespread rain and meaningful rain rain totals to most locations from Wednesday into early on Thursday. - A cooling trend will take place during the second half of the week into the weekend.

UPDATE

Issued at 640 AM EST TUE NOV 3 2026

Grids were freshened up based on recent observation trends. This led to no substantial changes at this point. Valley fog present in some locations south of the Mountain Parkway should lift and dissipate within a couple of hours after sunrise. Otherwise, a mile day is in store with temperatures expected to climb to 10 to 15 degrees above normal for early November.

LONG TERM

(Thursday through Monday) Issued at 425 AM EST TUE NOV 3 2026

Behind the shortwave trough and a cold front departing to the east, drier air will spread across the remainder of eastern KY on Thursday. This will result in a trend to drier weather as a trough begins to take shape over sections of the Central to eastern Conus. The upper low that will have reached the Great Lakes is progged to weaken to an open wave as it moves into Canada and a 500 mb shortwave trough axis should trek across the Great Lakes and near the Lower OH Valley by late Thursday night or Friday. Another upper low may develop in the Great Lakes vicinity and track into the Northeast/St Lawrence Valley to begin the weekend, while the 500 mb shortwave trough axis moves across the OH Valley and eastern KY area later Friday into early on Saturday. Another sfc cold front associated with trough will cross eastern KY at that point. Guidance generally has an increase in low and mid level rh with this boundary but moisture will be quite limited this far to the south. Isolated showers producing light rainfall cannot be ruled out. Yet another upper low/shortwave trough may move into eastern Canada to eastern Conus troughing to end the weekend and pass north of the OH Valley and send another cold front across eastern KY.

With upper level troughing moving across the eastern Conus this weekend, before shifting east of the OH Valley and eastern KY early next week, northwest flow aloft will be present. A trend to near normal if not a bit below normal temperatures is anticipated. Highs are forecast to reach the upper 50s to lower 60s this weekend, before temperatures trend colder for Sunday night and Monday behind the second cold front as sfc high pressure builds in. Lows could near the freezing mark or possibly fall below freezing for several valley locations and low lying areas over the weekend or early next week.

AVIATION

(For the 18Z TAFS through 18Z Wednesday afternoon) ISSUED AT 130 PM EST TUE NOV 3 2026

VFR conditions prevail across the area through this evening, although changes are anticipated overnight. As atmospheric moisture increases ahead of an approaching low pressure system, those clouds will thicken, with ceilings gradually lowering towards MVFR thresholds tomorrow morning. Expect rain showers to spread from west to east in the latter half of the forecast period, with strengthening southerly winds in this same time frame. Winds will strengthen aloft first, so some marginal LLWS is possible early tomorrow morning. Surface winds should be the lightest at northeastern terminals like KJKL tonight, so confidence in LLWS is greatest there. Once the stronger winds start to mix down after dawn tomorrow, any LLWS should give way to surface wind gusts in excess of 20 knots. So, in short, expect flight conditions to deteriorate as a storm system approaches the area tomorrow.
