Monday/Columbus Day:
The Columbus Day holiday is looking to be a cloudy, cool and breezy
washout for most, as beneficial stratiform rain bands to continue to
overspread the remainder of Southern New England. Wettest conditions
continue to be primarily focused south of the Mass Pike and
especially across eastern RI, southeast MA and Cape Cod. Latest NBM
24 hour rainfall probabilities offer strong probabilities for at
least one-half inch in this area, with lower probs for 1". Official
forecast has the highest QPF across southeast MA, eastern RI and the
Cape and Islands at around one-half to three-quarters of an inch
through Columbus Day. ******Did note a tendency across model guidance QPF
sources for less QPF across northern MA towards the NH/VT border
more removed from the coastal low and where drier air may be tougher
to scour out. I did reduce values a bit here to around a quarter to
third of an inch, but it is looking like southern areas stand the
best chance for the highest rain totals.********
