.NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --
High pressure to our north will extend south across our area
today while an upper ridge centered over the Eastern Great Lakes
pushes in from the west. This will leave us in a moderately dry
corridor between moisture in the Maritimes associated with an
upper low south of Nova Scotia, and an occlusion pressing
eastward along the western edge of the ridge. The day will begin
with some low clouds across the area. The low clouds will
likely dissipate by mid to late morning bringing a mostly sunny
midday. However, solar heating in the narrow ridge across our
area will result in cumulus building up beginning in early
afternoon and making for a partly to mostly cloudy afternoon.
Highs in the upper 50s to near 60 will be seasonable.

We will remain in a narrow ridge of high pressure both surface
and aloft tonight. Some patchy stratocumulus will linger across
the area with some isolated areas of fog in southern areas.
Otherwise, tonight will be tranquil and dry with low near 40.

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
-- Changed Discussion --
Models are in pretty good agreement for this ptn of the fcst in
that Sat and Sat Ngt look to be fair with intervals of cldnss as
weak sfc high pres holds ovr the FA. Sun will begin ptly sunny,
then become cldy and breezy in the Aftn as a s/wv an weakening
warm occluded frontal zone begins to apch from the W. Shwrs
from this system will msly occur ovr the Rgn durg Sun Ngt with
most areas receiving arnd a tenth of an inch with lcly 0.15 to
0.20 inches possible, warranting max PoPs in the likely range.

.LONG TERM /MONDAY THROUGH THURSDAY/...
-- Changed Discussion --
Models are in reasonable agreement that a break in shwr activity
ovr our FA will occur from mid Morn til Erly Aftn, following the
passage of a weakening warm occlusion and ahead of fairly strong
secondary cold front and associated s/wv from Hudson Bay. The
warmest air in the llvls will arrive durg this tm frame allowing
temps to get well into the 60s, perhaps even near 70 ovr inland
low trrn lctns. In the meantime, temps abv 700mb will begin
falling even ahead of the secondary cold front durg the Aftn,
with this vertical differential htg resulting in sct shwrs and
even possible thunderstorms msly Nrn/Cntrl areas ahead and alg
the secondary cold front mid to late Mon Aftn.

Shwrs will move E and dissipate behind the cold front Mon Eve,
with the rest of Mon Ngt and Tue looking to be fair, breezy and
cooler, with some llvl cold advcn SC cld cvr possible ovr Nrn
areas late Tue Morn into Aftn. Under Can sfc high pres, Tue Ngt
looks to be fair with dmnshg winds and cool spcly Nrn areas with
good radiational cooling.

Wed will start ptly cldy ovr the Rgn, then turn msly cldy from
the W as another weakening occluded sfc low and s/wv alf system
apchs from the Midwest. Shwrs from this system are most likely
going to impact our FA Wed Ngt into Thu, but longer range models
are not in good agreement on rnfl totals durg this tm frame,
with the 00z dtmnstc GFS the greatest and the corresponding
ECMWF much lighter, subsequently max PoPs were kept in the high
chc range. Longer range models are in a little more agreement
on possible more sig rnfl toward the weekend, currently just
beyond this fcst domain. Temps will be msly near normal for Wed
and Thu.
