Area Forecast Discussion
National Weather Service Buffalo NY
957 AM EDT MON JUL 18 2016
.SYNOPSIS...
A slow moving cold front will cross our region today...and while
this will generate some badly needed rainfall for some of the
luckier areas...it will also pose the risk for strong gusty
thunderstorms. High pressure over the Northern Plains will then
gradually build across the Great Lakes region. This will support us
with our next extended stretch of dry weather lasting through at
least Thursday.
&&
.NEAR TERM /THROUGH TONIGHT/...
The cold front is entering the Niagara Frontier region at 1345Z with
some satellite indications of cumulus congestus forming along the
Niagara Peninsula and radar indications of showers forming. With
higher dewpoints in the 70s pooling along and ahead of the front and
a pronounced theta-e ridge with a 35-40 knot low level jet located
axially along the ridge, expect rapid formation of convection along
the front, just south of the Lake Ontario shore.
Thunderstorms with locally heavy rain will continue to develop
during the course of the day, as the front presses southward and the
axis of the theta e ridge will push east.
The cold front will exit to our southeast tonight...while drier air
will continue to feed across the region ahead of an approaching
Canadian based sfc high. While this will translate into improved
weather for tonight...the passage of a weak secondary cold front
could keep some clouds over the region. After a night when
temperatures generally held above 70...tonight will definitely be
cooler. The mercury will settle into the mid and upper 50s across
much of the Srn Tier and across the North Country...while readings
will be close to 60 elsewhere.
&&
.SHORT TERM /TUESDAY THROUGH THURSDAY/...
During this period...sprawling surface-based ridging of Canadian
origins will slowly settle southeastward from the Upper Great Lakes
to a position just a little offshore of the Mid Atlantic coastline...
with this feature cresting directly over our region on Wednesday.
Meanwhile at the upper levels...its parent near-600 dm upper level
ridge over the Central Plains will expand to cover the vast majority
of the continental United States...while lingering broad/flat
troughing over the Great Lakes and Northeast lifts out into New
England and the Canadian Maritimes.
For our region...all of this will add up fair/dry and uneventful
weather dominating our region through this period...particularly
Tuesday and Wednesday when skies will also be mainly clear/sunny.
By Thursday there may be some partial increase in cloud cover as
a few weak impulses round the top of the upper level ridge and
begin heading toward our region...though at this point it appears
that any associated convection would be more than likely to remain
confined to Southern Ontario.
With respect to temperatures...the first 24 hours of this period
will be refreshingly cooler and drier as the aforementioned surface
ridge settles toward our region from the Upper Great Lakes. On
Tuesday 850 mb temps will average out between +8C to +11C and
will support afternoon highs ranging through the 70s...while
surface dewpoints will fall off into the upper 40s and lower 50s.
These same low dewpoints will then persist through Tuesday night...
when ideal conditions for radiational cooling (increasing ridging...
mainly clear skies...a dry airmass...and light winds) will allow
overnight lows to range between the upper 40s across interior
portions of the Southern Tier and North Country to the mid and
upper 50s along the lakeshores.
After that time...the expanding upper level ridge will feed a
persistent westerly flow of warmer air into our region...which
will result in our temperatures climbing to right around seasonal
averages on Wednesday...then back to above normal levels on
Thursday. More specifically...daytime highs are expected to
reach into the upper 70s to lower 80s Wednesday...then back to
the 85 to 90 degree range on Thursday as 850 mb temps steadily
rise to between +17C and +19C by the end of the period. This
said...humidity levels will be slower to recover with the massive
upper level ridge effectively blocking any influx of GOMEX-based
moisture into our region...with surface dewpoints remaining in the
very comfortable lower to mid 50s through Wednesday...before rising
into the lower 60s on Thursday.
&&
.LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/...
Late in the week and next weekend...the medium range guidance
remains in good agreement that the core of the massive upper
level ridge will slowly retrograde southwestward into the
Southern Plains and Desert Southwest. Over time...this will
eventually allow broad/flat troughing to redevelop across the
Great Lakes and Northeastern states as multiple weak to modest
shortwave impulses round the top of the upper level ridge...
then slide southeastward in the prevailing west-northwesterly
flow aloft.
In a general sense...at this juncture the medium range guidance
seems to be keying on two such impulses in particular...with
one of these glancing by to our northeast Thursday night into
Friday...with a second and potentially more significant feature
the digging toward our region over the course of the weekend.
At the surface...the former still appears likely to swing a
very weak cool front across our region between Thursday night
and Friday...with the latter then pushing a warm front across
the area on Saturday...quickly followed by its trailing cool
front between Saturday night/early Sunday.
While these systems should provide our region with our next
opportunities for some convection...at this juncture overall
convective potential and coverage with both still look to be
on the low side. This both due to the continued presence of
the broad upper level ridge over the Southern CONUS which would
preclude any connection to the Gulf of Mexico...as well as the
fact that the surface fronts would likely be lacking any noteworthy
upper level support over our region...with the latter likely
remaining well to our north. When you throw in the antecedent
drought conditions on top of all this...at this point it's tough
to suggest anything more than some broadbrush slight chance to
very low-end chance PoPs for late next week and next weekend.
What does appear much more certain is that Friday and Saturday
are likely to be uncomfortably hot...with 850 mb temps climbing
to between +18C and +21C Friday out ahead of the initial weak
cool front...and then potentially rising even another degree
or two higher than that on Saturday following the aforementioned
warm frontal passage. On both days...this would translate into
afternoon highs reaching into at least the upper 80s across the
higher terrain and the lower to mid 90s across our lower elevations...
with some potential for readings to be even a bit hotter than this
on Saturday were current model projections to actually come to
fruition. Meanwhile...nighttime lows would decidedly be on the
sultry side...ranging between the upper 60s and mid 70s each night
with the most uncomfortable conditions found across the lake plains.
Following the passage of the second cool front...temperatures may
finally pull back some for Sunday...but even then readings would
still be likely to average above normal with afternoon highs in
the mid to upper 80s currently appearing to be the most likely
outcome. Considering that next weekend roughly corresponds with
our climatologically warmest days of the year...all of this heat
would be right on schedule with respect to the calendar.
&&
.AVIATION /14Z MONDAY THROUGH FRIDAY/...
Generally VFR conditions will be found across Western and North
Central New York today...despite the passage of a pair of frontal
boundaries. These features will produce scattered showers and
thunderstorms though...with some storms possibly producing an hour
or so of MVFR conditions for sites such as KROC...KART and KJHW.
Tonight...high pressure will be approaching our region from the
Upper Great Lakes. This will provide fair VFR conditions across the
region along with light winds.
Outlook...
Tuesday through Thursday...VFR.
Friday...Mainly VFR. A chance of thunderstorms.
&&
.MARINE...
Small craft advisories will be in place across the New York
nearshore waters of the Lower Great Lakes and adjacent major
waterways today...as a tightening sfc pressure will be in place
ahead of an approaching cold front. This front will also help to
generate scattered showers and possibly some gusty thunderstorms.
As the front pushes southeast of the region this evening...the sfc
pressure gradient will weaken and this will allow winds and waves to
correspondingly drop off as we work through the night.
A large sfc high centered over the Upper Great Lakes tonight will
then build across the region Tuesday and Wednesday. This will
promote relatively light winds and negligible waves through at least
the middle of the week.
