.DISCUSSION...
Issued at 130 PM CDT Mon Apr 29 2024

A cold front will make slow west-to-east passage tonight.
Along/ahead of it, showers/storms advance and expand and we`ll
eventually see them come to an end in west-to-east fashion with
the fropa. Until then, some lightning and locally efficient/at
times heavy rains are possible hazards. Some 1-2" totals may
occur in portions of western Ky, but beyond localized/prone area
flood issues, our slightly to moderately dry ground conditions
should be able to handle that amount of rain. Clouds will clear
shortly thereafter, but seeing how this process takes us thru
much of the night, there is some potential for a wet near
surface layer to develop some fog or low clouds toward daybreak
as skies clear/winds become light. This may linger clouds into
early tmrw morning before daytime heating breaks the inversion
and mixes everything out and drier conditions onset for the mid
week. Temps remain on the warm side of seasonal with upper 70s
to lower 80s tmrw climbing toward the middle-upper 80s for
Wednesday-Thursday. The cold front`s passage draws dew points
down into/thru the 50s tmrw, but they`ll return to the lower 60s
by mid week, just as we are heating up again. That means daily
rain chances reappear by Thursday, as our upper ridge moves
east and troffing in the High Plains moves our direction. One
wave`s passage by week`s end spikes pops Friday, then a relative
pause occurs til more active weekend chances set up within a
belt of southwesterlies aloft that continues the fetch of
warm/moist air. Temps/dew points mirror earlier in the week when
60s back off to 50s dew points before returning to the 60s
again, with temps in the 70s again Friday returning to around
80 for the weekend.

.AVIATION /18Z TAFS THROUGH 18Z TUESDAY/...
Issued at 130 PM CDT Mon Apr 29 2024

Mostly VFR CIGS are forecast, but with showers/storms active in
the first half of the package, some lower bases into restricted
categories cannot be ruled out. The rain occurs along/ahead of a
cold front, which completes its west-to-east passage overnight.
Resultant clearing skies/light winds after passage may allow
wetted surface grounds to develop some fog before the drier dew
points fully work in, so there`s an additional chance for
restricted flight weather around daybreak for both CIGS/VSBYS.
Any such left-over/lingering clouds should eventually disperse
during the planning phase hours of the forecast.
