No worries
*** Possible renewed Flash Flooding & a few severe storms with
an isolated tornado possible ***
Remnants of Henri begin to advect eastward back across southern
New England. Modest synoptic scale lift with good cyclonic
curvature to the mid level flow, along with some enhancement via LFQ
of upper level jet streak. This combined with PWATs increasing
back to 2+ inches, scattered showers and storms will be capable
of producing tropical downpours. This combined with today`s
heavy rainfall and areas of flash flooding, increasing the risk
for renewed flooding tomorrow across CT, western- central MA
possible into RI.
Then farther east into eastern MA, breaks of sunshine should
promote highs of 80-85 degs along with dew pts 70-75. This will
yield MLCAPES up to 1000 j/kg or so. Thus, modest instability
(long skinny CAPE) along with low LCLs. Modest low level shear
as well, with 0-1 km vector offering up to 30 kt of shear. This
shear and instability profile combined with remnants of Henri,
high dew pts/low LCLs may be sufficient for a few rotating
updrafts, with risk focused across eastern MA including the
Merrimack River Valley. For now, including gusty winds and heavy
rain into the forecast. Later shifts, if confidence increases
may want to insert stronger wording.
