.DISCUSSION...
KEY MESSAGE 1...Wet and unsettled weather returns today into
this weekend. Continued above normal temperatures before cooler
conditions arrive Sunday and beyond. Dry weather expected most
of next week.
High pressure well southeast of New England will maintain
southerly winds into tonight. A slow-moving cold front
approaches from the west today, then stalls across our region
Friday while waves of low pressure travel along it. A final low
pressure is expected to move into the Maritimes Sunday, finally
moving this front offshore.
The greatest rainfall chances will be across western MA today.
The focus then shifts across RI and southeast MA tonight into
Saturday. Relatively light rainfall anticipated today and
tonight. The same cannot be said for Friday into Saturday
morning. The prolonged nature of this rainfall, as well as the
well above normal amounts of moisture, should lead to a
significant rainfall. The latest guidance increased potential
rainfall amounts yet again. However, there is only moderate
confidence in the location of the axis of heaviest rainfall.
Variance in rainfall 48-hour amounts in the ensembles were
between 0.75-1.75". This is a signal that not all the details
are refined quite yet. Further changes are possible with later
forecasts.
All that said, our best estimate is for 0.50-1.00" of rainfall
across the western half of southern New England through
Saturday. Farther east, rainfall of 1.00-2.00" is more likely.
A narrow band of rainfall up to 3" is possible. Again, the exact
locations this sets up is not yet known, but the most likely
area for be from southern RI into southeast MA.
Fortunately, we've been very dry for a while and flash flood
guidance is high. Still not expecting flash flooding to be an
issue. Some poor drainage/urban flooding is possible, especially
given the possibility of leaves blocking drainage this time of
year. There continues to be a marginal risk within the Excessive
Rainfall Outlook for Friday into Saturday.
Rain chances drop off Saturday morning but showers will continue to
be possible through Sunday morning with a cyclonic flow overhead;
nothing like Friday/Friday night though. NW flow ushers in a colder,
albeit closer to normal, airmass for early next week with high
temperatures returning to the 50s.
A series of fronts then move across southern New England next
week. However, limited moisture should only mean periods of
clouds at times and mainly dry weather.
