NWS finally gave up on their zone calls off 60's tomorrow, switching to higher mid 50's, but they still have another 3-5 to pare off if the most of the Meso's are right.
Most models are a nice soaking with a lot more rain next week. For example, the Euro has 3-5" on the ground in the next 8 days. GFS 2.5-4".
LSV rain through Monday 0Z/Sunday evening:
Nam 1.5-2
Rgem .5-1
Fv3 (through 8AM Sunday) ~1"
GFS 1.25-1.75
Euro .75-1.5
HRRR (only through ~ 2AM Sunday) 1/2"-3/4"
Fv3, HRRR and Nam are most or all day soakers, albeit it some of the rain is light, for LSV and East PA tomorrow...Rgem some showers but less during the daytime tomorrow. Most locales stay between 48 and 52 the entire daylight time.
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.
