I think of the main models, only the EC would have you break 60 on Sat. Nam, Rgem, GFS, CMC all have upper 40's to mid 50's Sat at 2PM. I did not check for midnight highs, etc.
GFS and mesos all paint a sad sack picture for Sat and Sun. Rain and 48-53 degrees for Central and Eastern areas followed by warmer and on and off rain the rest of next week.
MR and LR is much less warm.
I saw it did not cool down over there. Elevation thing per the current Wundermap (though THV got 51 I think.) Up to 58 already. The low was back around 5AM.
When I lived away from this area in the LSV I remember it raining moderate amounts more often, yes. I actually remember real synoptic/low pressure systems some summers. Now it is rare we get one to go under us here.
IMO, anything less than 1/4" every 3-4 days is not going to cut it in May-Sept. Getting 2" of rain in a month, if spread out/falling every 3-4 days, is better than 4" of rain only spread out over 3 total days. The grass will go dormant or die if it only rains 3 days in a month.
