Well NAM 00z (June 1)is not as optimistic as today’s 12-18z runs (May 31). It does keep the warm front with backed surface winds, but weaker through all levels. Surface winds are showing 5-10 knts but they are not much weaker above 925mb though the run has weakened them some what.  There could be to much convective feed back from upstream, only time will tell. The models still show some isolated convection out ahead of the main precip on Tuesday b/w 21-00z along the warm from near the IN/MI border in SW SC MI.  The CAPE is around 1000-1500j/kg but barely breaching the border into MI.  Still something to keep an eye on as it is close to home and i am free at the 21z time frame. Based off of the 12-18z I would have seen SPC place the slight further north for Day 2 tomorrow. Looking at this 00z run I would leave it were it is  but nudge it closer to the border of MI and IN.
