Area Forecast Discussion
National Weather Service Buffalo NY
513 PM EDT Wed Jun 3 2020

.SYNOPSIS...
Weak high pressure will generally support fair weather tonight
through much of Friday. A cold front will allow for some unsettled
weather Friday and Friday night...then fair weather will return
during the weekend through the first half of next week.

&&

.NEAR TERM /THROUGH THURSDAY/...
Weak high pressure will support fair weather for most areas through
Thursday.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/...
Weak high pressure will remain overhead Thursday night before being
pushed east out of the region by the next frontal system late
Friday. That being said, Thursday night through the first half of
Friday will be dry with mostly clear to partly cloudy skies. Lows
Thursday night will drop down into the upper 50s in the North
Country, whereas the remainder of the region will see low to mid 60s.

A weak midlevel trough and surface cold front will slide through the
central Great Lakes and Southern Ontario throughout the day on
Friday, before developing stronger synoptic support and reaching New
York Friday night. That being said, Friday is expected to be
primarily dry with the slight chance of a few showers and
thunderstorms forming on the mesoscale boundaries forming off of the
lakes. 850 mb temperatures are alluding to near +15C temperatures
overhead, which will support highs to climb up into the low to mid
80s.

The aforementioned to midlevel trough and associated surface cold
front will pass through the region Friday night and Saturday
morning. As the front passes through, expect scattered showers and
storms due to the lack of atmospheric forcing available at this
time. Throughout the day on Saturday, the midlevel trough will
continue to push east and begin to dig as is encroaches into New
England. While the trough will be digging and thus steepening the
midlevel lapse rates, the potential for thunderstorms will have
ended due to the passage of the front, therefore expect showers
throughout the day on Saturday. Also, due to the cold frontal
passage, cold air advection will act to hinder the warm highs like
the day before, expect highs to be in the 70s.

Shower coverage will gradually end from west to east throughout
Saturday evening and night as the midlevel trough moves further east
into New England. As stated previously, the cold air advection
scheme will keep things on the cooler side. Highs will drop into the
low to mid 50s Saturday night.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
A stretch of dry weather will develop through the first half of next
week as a strong mid/upper level ridge moves from the central US
into the Ohio Valley and Great Lakes. This will provide dry weather
Sunday through Tuesday. As the ridge moves toward the coast a
southerly flow of warmer and wetter (including the remnants of
Cristobal) air begins to overspread the region Wednesday.

Temperatures will be quite cool on Sunday with highs in the mid to
upper 60s and lows in the mid to upper 40s. High temperatures warm
to the low 70s on Monday and into the upper 70s to low 80s on
Tuesday and Wednesday.

&&

.AVIATION /21Z WEDNESDAY THROUGH MONDAY/...
Weak high pressure moving across the region tonight and Thursday
will maintain VFR conditions for most areas. The only issue will be
some light fog that reduce vsbys to MVFR levels in some areas late
tonight. IFR vsbys may develop across parts of the Southern Tier
between 8 and 12z.

Outlook...

Thursday night and Friday...VFR.
Friday night through Saturday...Mainly VFR. A few showers possible.
Sunday and Monday...VFR.

&&

.MARINE...
While fresh southwesterlies will keep choppy conditions in place on
Lake Erie early this evening...weak high pressure moving across the
Lower Great Lakes will support generally light winds and negligible
waves tonight through Friday.

&&

.BUF WATCHES/WARNINGS/ADVISORIES...
NY...None.
MARINE...None.
