Lo and behold, both that Thurs (10), as well as the MaxT
for Wed, Mar 9 (11) have large spread between the PMaxT
(Mean) and NBM.
Looking ever closer, at the tails, reveals some of the
largest overall spread I have seen, though I don't often
look at Montana weather. Both that Wed and Thurs have
overall spread of 48 degrees! Not shown, but the Tues, Mar
8 overall spread is 53 degrees, ranging from 50 to negative
3!! Fri morn Mar11 NBM MinT has a range of 58!! (33 to
negative 25)
Wed MaxT (37 to negative 11)
Thurs MaxT (44 to negative 4)
Got me thinking about the largest the NBM has ever
forecast. I know this is probably not atypical for such
areas, but would be curious what kinds of maximum spreads
others have seen.
Interested too, is how we've seen, for some events, the
Obs STILL fall outside large ranges at times!!
