DISCUSSION
Issued at 146 PM EDT Mon May 6 2024

Powerhouse upper wave over the cntrl Rockies will close off across the wrn Dakotas before spinning out through the Great Lakes Thu-Fri.
Downstream warm sector will broaden north into the OH valley tomorrow and support decaying plains leftovers Tue morning. Cloud debris and potential clearing in wake of morning activity will dictate possible late day svr risk but destabilization likely hindered here and which subdues overall svr risk.

Ewd pinwheeling upper low and attendant cold front will progress into wrn areas Wed evening and ewd overnight. Strong/sharp return flow ahead of this along with proximity of sfc warm frontal zone general south of US24 may pose a resultant higher risk but potential outflow spoiler remnant from dy1 further south may squelch that risk.
Nevertheless high chance to low likely pops retained in more favorable periods.

Thereafter cool and showery as wrn flank of elongating upper low holds back through the srn lakes, reinforced by secondary disturbances digging down across the lakes Sat and again late Sun.

AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/
Issued at 1234 AM EDT Tue May 7 2024

A warm front will lift into northern IN late this morning and afternoon with a couple rounds of convection expected. The first will be associated with a decaying line of convection that will track through from west to east late this morning into the early afternoon. Moisture advection in advance should allow cigs to lower into MVFR or low VFR with an hour or two of showers and embedded thunder expected. Greater concern is for a round of more vigorous surface based convection mid-late afternoon as instability increases just in time for a MCV to track through with scattered strong-severe storms possible. Opted to hold with a VCTS mention for now given lingering uncertainties. VFR/dry otherwise into tonight behind this feature.
