Area forecast discussion, Oct 10, 9:56 AM EDT, 4 hours 46 minutes before
Area Forecast Discussion
National Weather Service Boston/Norton MA
956 AM EDT Wed Oct 10 2018
.SYNOPSIS...
Warm and humid conditions continue today. Scattered showers may
move into the region late tonight into early Thursday as a
backdoor cold front slowly pushes south before stalling across
central New England. Showers and a few thunderstorms will push
across the region ahead of an approaching cold front Thursday
through Friday. Michael will likely track well southeast of
the 40N/70W benchmark, keeping the threat for heavy rain across
far southeast New England with the best chance across outer Cape
Cod and Nantucket Friday. High pressure will build in for the
weekend, bringing dry but rather cool fall like weather.
Showers may return during Monday or Tuesday.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
10 am update...
Abundant sunshine and humid conditions. Warm air advection ongoing
aloft with H925 temperatures warming to +20C. As temperatures
yesterday exceeded expectations given cloud cover, with the lack
thereof opted to take the maximum of all available guidance giving
us highs in the low to mid 80s for much of S New England. May fall
a few degrees short in some areas but the message is there as SW
interior winds increase that much of the region will see 80s for
today. Gusts up around 20 mph, especially S/SE coastal. Dewpoints
still around the mid 60s. Muggy. For early October is more like
early September.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/...
Tonight...
Mid level ridge/cutoff high across the western Atlantic pushes
offshore, allowing H5 heights to lower. Noting pressure surge
working S-SW along the Maine coast, with an associated backdoor
cold front trying to shift S. May see some showers try to push
into N central and NE Mass around or after midnight, but it will
be tough for the front to work much further S. In the meantime,
strong low pressure will push across the Great Lakes, with its
associated cold front trying to push E from the Ohio Valley to
the mid Gulf Coast. Lastly, the moisture plume feeding NE ahead
of the front, aided by the approaching Hurricane Michael into
the FL panhandle, will see surge of tropical moisture northward.
PWATs across central and W areas increase to around 2 inches,
or around 3-4 SD above normal.
Expect increasing chance for showers across the region, with
the best chance across W Mass/N central CT after midnight. Will
also see patchy fog develop overnight, with visibility lowering
to around 1SM across the E slopes of the Berkshires and possibly
into the Merrimack Valley.
May see quite a range in temps overnight, depending upon how
much the cooler air pushes into N central and NE Mass. Current
thinking suggests temps bottoming out in the 55-60 degree range
from about a KBOS-KORH line N and E, ranging to the upper 60s
across the mid and lower CT valley.
Thursday...
Deep moisture ahead of the approaching front and from Michael
down the coast will keep an increasing PWAT plume pushing across
the region during the day. PWAT values increase to 2.1 to 2.3
inches, up to 4-5 SD above normal. Showers will become
widespread from W-E as the cold front approaches from the W,
while the front across central New England retreats back N.
With the high moisture plume in place, will see locally heavy
downpours that may cause brief poor drainage and urban flooding
in some spots. Also noting increasing instability ahead of the
front, with K indices up to the mid 30s moving across the region
during the day. Have also mentioned a low chance for
thunderstorms as well.
May see SW winds gusting to 20-25 kt along the S coast during
Thu afternoon as good mixing returns along with a good low level
jet passing along S coastal areas.
Expect temps to range from the mid 60s to near 70 across N
central/NE Mass to the mid 70s across the lower CT valley.
&&
.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
Big Picture...
Atlantic high pressure retreats south. Northern jet stream digs
south with falling heights over the northern USA. Upper low
associated with Hurricane Michael or its remnants moves north from
the Gulf of Mexico, then gets caught in the sinking mid-latitude
flow and its movement turns toward the northeast and passes well
south of New England. One shortwave from the Pacific Northwest
sweeps east and over our area Saturday. A second shortwave from
Northern Canada digs south to the Great Lakes and Northeast USA
early next week.
Upper contour heights are similar through Sunday morning but then
show differences. In particular the second of the shortwaves crosses
our area at different times depending on the model. The GFS is about
12 hours faster than the ECMWF but similar to the GGEM. Confidence
is high Friday, then diminishes to low by Monday and Tuesday.
Contour heights are above normal through Friday, then fall to below
normal over the weekend and rise a little early next week. We agree
with the trend to colder temps behind the Thursday night front and
lingering through the weekend. Guidance temps show a warming trend
early next week, but not as much as the height increase suggests. We
will go with the slower warming.
Concerns...
Thursday night-Friday...
Cold front moves through the region from 00Z to 06Z. Michael or its
remnants moves northeast from coastal North Carolina following the
upper flow as noted above. This takes the center across 38.5N/70W,
well south of Nantucket during Friday.
The plume of high PW air remains over Srn New England through
midnight and along the South Coast through the night. This suggests
showers and embedded local downpours for part of the night inland
and all night near the South Coast. A SW 40-50 knot low level jet is
along the south coastal areas Thursday night, then shifts south and
offshore overnight as the cold front moves through. This may bring
wind gusts of 30-40 mph in southern areas until the cold front
approaches, then winds will diminish.
We will continue the potential for showers/thunder/local downpours,
diminishing most areas overnight. Winds then shift from the
northwest for Friday. Temperatures will cool overnight as northwest
winds bring in lower dew points inland. Less certain of that along
the coast where precipitation will continue to moisten the air. Min
temps from around 50 northwest to the lower 60s over the Islands.
The plume of moisture will linger along the South Coast Friday
morning, but should shift offshore during the afternoon. Expect dry
weather in most of the area, but morning showers southeast of a
Plymouth-Providence line.
Finally, the passage of Michael will bring a period of high surf
to the exposed South Coast, especially the Islands and east-
facing coast of Outer Cape Cod. Some of this will linger into
Saturday.
Weekend...
Weak shortwave and cold pool move across our area Saturday. Cross
sections show medium depth of moisture with this shortwave, so a
period of clouds is likely. But the air below 850 mb is expected to
be dry so no precip is forecast. Temps aloft are forecast at an 850
mb equivalent of 0C to -2C. Max temps are based on this as well as
the expected morning temperatures, adding 5-7F to the latter.
High pressure overhead and fair skies should allow radiational
cooling, and with dew points in the mid 30s to low 40s we expect min
temps in the mid 30s to mid 40s. This means potential for frost in
some areas, including northern Mass and the low spots/bogs in the
coastal plain.
Fair weather Sunday with mixed layer temps supporting max temps in
the mid 50s to low 60s.
Monday-Tuesday...
As noted above, timing of the next shortwave and its cold front are
in question. But expect clouds and showers to arrive either later
Sunday night through Monday, or later Monday through early Tuesday.
We will go with a compromise on timing, with chance pops for showers
each day.
