Area Forecast Discussion National Weather Service Buffalo NY 1031 PM EDT Mon Jun 14 2021

SYNOPSIS. Showers and thunderstorms that blossomed across the Niagara Frontier early this evening have diminished such that the last fragments are crossing southwestern NY. An upper low will then move through the area tonight and Tuesday, bringing back another period of showers to the area. Cooler conditions will then take hold of the area through mid-week.

NEAR TERM /THROUGH TUESDAY/. As a resultant of the lake breeze boundaries that set up earlier this afternoon, showers and thunderstorms blossomed over the Canadian peninsula and entered the Niagara Frontier earlier this evening. These showers and thunderstorms have crossed Northwestern New York throughout the rest of the evening, and are now finishing their trek across the Southern Tier.

Then, a trailing upper low is evident on water vapor imagery and will slide toward WNY this evening. This will slowly edge across NYS through Tuesday and finally exit toward the Lake Champlain area tomorrow night. Deformation around this feature will draw a bit of a trowal airstream and attendant rain/showers back into the area from overnight tonight across WNY which translates eastward on Tuesday toward the North Country. The associated clouds will keep temperatures back on Tuesday, especially in the North Country, where rain chances will continue higher into the "heat" of the day.

SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/. The mid & upper level low over the region will finally push northeast out of the area, and open/phase with the overall trough over the region. This will lead the way to less active weather starting Tuesday night, as a large sfc high tracks east from the Upper Midwest. The large trough over the Northeast and Great Lakes will remain in place through Thursday, slowly pushing east, giving way to a narrow, sharp ridge that will briefly move through the area.

The area of high pressure will track from the Central Great Lakes on Tuesday night to near the OBX of NC by Friday morning. This will provide quiet weather for most of the area for the entire short term period.

With the high pressure to the northwest of the region, resulting northerly winds will cause some cooler temperatures for Wednesday, with highs in the mid 60s to near 70, and a few low 60s possible for the higher terrain. As the area of high pressure tracks southeast, temperatures will warm on Thursday to the low and mid 70s, with some upper 60s for the higher terrain.

Temperatures on Tuesday night and Wednesday night could be cool enough to have some patchy frost in the cooler spots of the Southern Tier and North Country.

LONG TERM /FRIDAY THROUGH MONDAY/. As the high pressure tracks southeast, an area of low pressure will track across Ontario and into Quebec, with its trailing cold front (and pre-frontal trough) crossing Western and North Central NY late Friday afternoon into Saturday morning. Showers and thunderstorms will be possible as the trough and front cross the area. Behind the passing cold front, the potential for showers and some thunderstorms will continue through most of Saturday as the axis of the larger scale trough crosses the region.

High pressure will provide for quiet weather to finish off the weekend on Sunday, but a few showers may linger for eastern portions of the area which will be closest to the upper level trough. Dry weather will continue into most of Monday, with the chance for showers increasing from southwest to northeast through the day. Chance POPs should make it up to the Niagara Frontier and the Northern Finger Lakes by mid-afternoon. This increased shower potential starting on Monday will be due to an approaching trough

Temperatures during the long term will be in the mid to upper 70s for most areas, with some low 80s possible on Friday and Monday, and some low 70s possible for the higher terrain over the weekend.

AVIATION /03Z TUESDAY THROUGH SATURDAY/. Mostly VFR flight conditions this evening, with the one exception being the tail end of the shower and thunderstorm development crossing the Southern Tier this evening, though this activity appears to have passed the KJHW terminal.

Otherwise, another wave enters the area and with abundant low level moisture, IFR stratus and rain will return from west to east by morning. Cigs will improve as daytime Tuesday ensues, even as rain continue to be possibly generally from KROC eastward during the daytime.

Outlook .

Tuesday . Starting the day IFR in many places west of KROC. Elsewhere, VFR/MVFR conditions will likely remain as a chance of showers increases from west to east. Wednesday through Saturday . VFR.

MARINE. Light westerly winds across both lakes this evening, is resulting in 1 to 2 ft waves. Another system brings showers back to Lake Erie and the Niagara River overnight tonight that will slide east on Tuesday. Northwesterly breezes will pick up on Tuesday but probably remain below SCA.
