GGEM doors Tue night into Wed. RGEM and euro are hot right through. Looks like NCEP and UKMET have the early door, GGEM and ICON the late Tue/Wed door, and EC and RGEM remain hot.
John it makes more sense if you use these obs from ISU

They don’t covert and display the high frequency obs to avoid the confusion. You can get the temp in whole deg C from the T group though. The hourly METARs have the tenths and get the conversion to deg F.
Slip that sfc low a little further south on Tue and we wedge all day up here like most of Maine. It’s not difficult to envision that happening with the BD/seabreeze airmass already in place in the morning. Get enough sun though and we mix that shallow cool air right out.
6z euro definitely cooler than 00z for up here. The GFS is likely overdone…think I’d lean toward the NAM numbers with better diurnal recovery. Although 12z is rolling out now so we’ll see how it changes.
