Synopsis
High pressure will remain anchored along the mid-atlantic coastline
through the upcoming weekend with fair weather and above normal
temperatures. The pattern will become more unsettled and cooler
next week.

Near term through Friday
A dry cold front is in the process of crossing the area late this
afternoon with just a modest increase in clouds, mainly east of lake
ontario. This front will move southeast across the area and exit by
late evening, taking most of the limited cloud cover with it. This
will leave mainly clear skies overnight.

Cooler air will build in behind the front with lows dropping into
the 40s, perhaps a few locales in upper 30s across the southern tier
and north country. Dry air and lingering graident flow will limit
fog development to only the deepest southern tier valleys late
tonight.

Friday, another fair weather dry with high pressure remaining
dominant. Sunshine will offset weak cold air advection with
most high temperatures in the mid to upper 60s.

Short term Friday night through Saturday night
Friday night and Saturday a large and expansive area of high
pressure will remain over the east coast, with abundant sunshine
and above normal temperatures. Highs will be some 15- 20
degrees above normal Saturday as +12 to +14c 850 hpa
temperatures reach our region with the surface high slightly
displaced to the east. Dry ground and a light southerly wind
should push temperatures into the 70s, with an 80f reading not
out of the question somewhere across the lake plain genesee
valley... Which is typically our warmest area. Record highs may
be just out of reach, which include for this date: buffalo
81f 1894, rochester 80f 2007 and watertown 78f 1979.

Dewpoints will begin to slowly rise Friday night and into the
weekend... Such that valley fog at night will be possible through
southwest nys.

Long term Sunday through Thursday
Another fine day is on tap for Sunday as a seasonably strong 500mb
ridge over the east coast with surface high pressure over the
western atlantic will bring plenty of sunshine across western and
north central new york. A light southerly flow will help
temperatures run 15 to 20 degrees above normal with highs forecast
to climb into the low to mid 70s. Record highs for all three climate
sites should remain safe. Sunday night will remain mild with mainly
clear skies as high pressure will still be in control and dewpoints
run in the 50s. Expect lows to range from the low 50s well inland to
upper 50s near the lakes.

Differences in model timing of an approaching front remain for
Monday with the 1019 12z GFS continuing to shift the front over our
region during the day while the 1019 12z ec remains about 12 hours
slower holding the fronts arrival off until Monday night. Have held
onto 20 30 pops on Monday which favor the ec timing but still cover
for a possible earlier arrival with the gfs. Pops for wny then
increase to 60 70 for Monday night with high pressure still favoring
mainly dry weather across cny. With the slower arrival of the front,
temperatures will remain on the mild side Monday.

The wettest period looks to lock in on Tuesday as the frontal zone
stalls across our region and one or more waves of low pressure shift
north along the front. Have continued 60-70 pops for Tuesday as both
gfs ec models are in agreement with a surface low lifting north
across new york. The GFS shows a potentially moisture rich airmass
will move into place along the front with a connection to the gulf
of mexico which could push pwats above 1.5 inches or more. Wpc day 4-
5 QPF shows a swath of 1-1.5 inches of rain over southwestern new
york. Temperatures will run near normal (mid-upper 50s) Tuesday.

Chance pops are featured for Wednesday as the mid-level trough and
cold advection support showery weather in the wake of the front.

Below normal temps should be expected for Wednesday as 850mb temps
dip to or below zero 0 which would support temps likely struggling
to break above 50 in many locations and may support some lake
enhancement as well into Wednesday night. The coolest low temps
Wednesday night dip into the upper 30s which should still keep a
threat of any snow out of the forecast for now.

Thursday then looks to bring back some dry weather in both GFS and
ec models as western and north-central ny comes under the influence
of a narrow ridge separating a digging trough in the northern plains
and potential developing coastal storm just off the mid-atlantic
coast. Temps forecast near normal with partly sunny skies.

Aviation 22z Thursday through Tuesday
Vfr conditions will prevail through this evening as high pressure
remains anchored over the mid atlantic states, with a ridge
extending northward into the eastern great lakes. A weak and dry
cold front will move across the region this evening. Southwest winds
will gust to 30 knots across the lake plains through early evening
before quickly diminishing.

Expect moreVFR conditions tonight as an axis of high pressure
ridges back into the lower great lakes region. Dry air and
lingering graident winds will limit the potential for fog
tonight.

Outlook...

Friday through Sunday...VFR except for local ifr in river valley fog
each late night and early morning.

Monday...VFR MVFR with a chance of showers.

Tuesday... MVFR ifr with showers likely.

Marine
Tight pressure gradient will remain over the eastern great lakes into
this evening. This will maintain small craft headlines for most of
the lakes with moderate to strong southwest breezes which will
shift to the west this evening. Winds will diminish on Friday as
the surface ridge axis moves back closer to area.
