.DISCUSSION...
Issued at 236 AM EDT Sun Apr 28 2024

Vigorous warm advection in progress on nose of LLJ through the wrn
OH valley leading to a disorganized area of showers and embedded
thunder from cntrl IL newd through nrn IN. Expect this will continue
to lift north into srn MI by daybreak and diminish. Thereafter
turning warm and windy although cloud cover may be slow to shake
this aftn and curb even warmer temps than are currently forecast.

Potent shortwave over wrn NE will lift into ern SD tonight as cold
frontal zone washes out ewd across the lakes on Mon. Little more
than a band of decaying showers expected along this late tonight far
west and across the remainder of the cwa Mon. Next nrn stream wave
tracking through the nrn Rockies Mon-Tue turns left into Canada and
has trended north which now looks to favor a mainly dry period Tue-
early Thu before rain chances reappear ahead of a more substantial
sys ejecting out of the cntrl Rockies Fri. Will make targeted cuts
to overtly messy blended pops to account.

.AVIATION /06Z TAFS THROUGH 06Z MONDAY/...
Issued at 1240 AM EDT Sun Apr 28 2024

We are beginning to see an increase in shower/storm coverage. At
this time, much of the shower/storm activity is located along the US
30 corridor. Into the overnight hours, expect this activity to
progress north with the help of the low level jet. Additional influx
of moisture into the area with increased convergence may aid in an
increase in chances of thunderstorms with some training of cells
possible overnight, especially in northwest Indiana including KSBN.
Once rain/storms exit (which should be before 12Z), expect VFR
conditions to prevail alongside gusty winds up to 25-30 kts
throughout the day Sunday.
