Area Forecast Discussion
National Weather Service Buffalo NY
342 AM EDT Sat Mar 22 2025

.SYNOPSIS...
While fair dry weather will persist across the vast majority of our
region tonight...a fairly robust cold front approaching from the
Upper Great Lakes could generate some showers showers over the FAR
western counties towards daybreak. The front will plow across the
area on Saturday with gusty winds and fairly widespread showers to
mark the passage. High pressure will then return to promote fair
weather for Saturday night and Sunday.

&&

.NEAR TERM /THROUGH TODAY/...
A mid level ridge is now just east of our forecast area this
late evening and will help to guarantee fair dry weather for
the vast majority of the region tonight...although a cold front
approaching from the Upper Great Lakes may generate some showers
over the FAR western counties towards daybreak. Temperatures
tonight will actually bottom out fairly early...as a deepening
southerly flow ahead of the aforementioned cold front will
support a subtle non-diurnal temp trend. The mercury will be in
the low to mid 30s this evening then will slowly climb closer to
40 by morning.

The weekend will then start off somewhat unsettled...as mixed rain
and snow showers over the far western counties early in the morning
will spread across the remainder of the forecast area before midday.
The forcing for the shower activity will come from a robust cold
front that charge through the region. As we work our way through the
afternoon...the front will quickly exit across New England. Notably
drier air will immediately charge across the region in the wake of
the front...so the showers will end from west during the afternoon
and early evening with some sun actually returning to many of the
western counties. All of this will be accompanied by gusty west to
southwest winds of up to 35 mph.

A burgeoning shortwave ridge over the Upper Great Lakes Saturday
night will push a wedge of sfc high pressure over our region. While
a leftover rain or wet snow shower could still be found over the
North country EARLY in the evening...this scenario will guarantee
that the night will be characterized by fair dry weather along with
diminishing winds.

&&

.SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/...
Surface high pressure across the region Sunday morning will slide
east through the day, with a mid level ridge cresting over the
region. This will result in a fair weather day with a gradual
increase in higher level cloud cover from the west through the day.

Rapid progression of two mid level systems places the eastern Great
Lakes in line for the next round of precipitation by Sunday night.
Surface low pressure pushing through the upper Great lakes will
tap into plenty of Gulf moisture. Thermal profiles suggesting
some risk for some wet snow early in the event, with the
greatest chance for a rain/snow mix or all snow will be across
higher terrain and North Country. A coating of snow is certainly
possible for these areas.

Warmer air wraps into the system later Sunday night into Monday as
the system occludes. This will allow any snow to change to rain by
Monday as temperatures work through the 40s, with 50s for the
Genesee Valley and western Finger Lakes, although southwest winds
will become brisk, particularly across the Niagara Frontier.

A colder airmass spreads into the region Monday night behind the
system cold front. Moist cyclonic flow will maintain the risk for
for showers, mainly east of the lakes where upslope enhancement will
likely come into play. The falling temperatures will encourage all
precipitation to change back over to snow overnight. Some minor
accumulations are possible across the higher terrain east of both
lakes, with up to an inch east of Lake Erie and 1-2" on the Tug Hill.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
Continued unsettled pattern briefly becomes more amplified through
mid week with a ridge building over the western and central CONUS
with a downstream digging trough across the eastern United States.
Disturbances rotating through the cool, moist cyclonic flow will
keep chances for rain and snow showers (mainly nocturnal snow with
exception of higher terrain) in the forecast through Wednesday/
Wednesday night with chilly conditions.

Model consensus diverges some in the finer details for the back half
of the period, however appears main trough axis should swing through
by Thursday with downstream ridging quickly building in from the
west drying things out. This drier weather may be brief with some
warmer air and increasing moisture bringing the next chance for some
rain/snow showers again Thursday night, becoming all liquid as we
close out the work week.

Otherwise, it will be chilly with below average temperatures through
much of the period, then nearing normal readings by the tail end of
the work week.

.AVIATION /08Z SATURDAY THROUGH WEDNESDAY/...
VFR flight conditions reside across western and north-central NY
late tonight. A strong cold front is approaching from the west and
clouds will thicken and showers will enter far western NY by
daybreak Saturday. The front will quickly move across the region
Saturday with rain showers spreading eastward through the morning.
Cold air will filter into the region behind the front and some rain
showers will changeover to snow, mainly across the higher terrain
east of the Lakes Saturday afternoon. Dry air will move into the
region and clearing will occur as early as Saturday afternoon for
western NY. Further clearing will occur to the east Saturday
evening, with lake effect clouds lingering southeast of the Lakes.

A 40kt low level jet may produce low level wind shear at KIAG/KROC
late tonight into Saturday morning. Diurnal mixing especially behind
the cold front will create a well mixed boundary layer with gusts 25
to 35 mph through the afternoon.

Flight conditions will become MVFR with rain showers Saturday. IFR
conditions are possible across the higher terrain east of Lake Erie
early Saturday afternoon. Flight conditions will improve to VFR
across western NY Saturday afternoon, with the exception of low
clouds persisting across the higher terrain. Conditions will improve
to VFR at KART Saturday evening.

Outlook...

Saturday night...Mainly VFR.
Sunday...VFR conditions. Snow developing and changing to rain Sunday
night. IFR to MVFR conditions.
Monday...MVFR CIGS with rain and snow showers likely.
Tuesday and Wednesday ...MVFR CIGS with a chance of rain and snow
showers.

.MARINE...
High pressure ridged across the Lower Lakes this late afternoon
has allowed for the winds and waves to subside below small craft
criteria.

Moderate southerlies will develop tonight and then freshen on
Saturday, as the next cold front moves through the region. Another
round of small craft headlines will be likely during this time.
