Area Forecast Discussion National Weather Service Buffalo NY 1047 AM EDT Sat Jun 22 2024

Warm and humid weather will continue this weekend. An oscillating frontal boundary will support showers and thunderstorms this weekend with the risk of torrential downpours and severe weather.

A frontal boundary will continue to oscillate across the northern portions of New York State, supporting plenty of instability for showers and thunderstorms through this afternoon. Convection will be mainly favored along lake breeze boundaries and in close proximity to the frontal boundary. Temperatures will continue to be warm, especially south of the boundary. Highs will range in the low to mid 80s, perhaps a few readings near 90F for areas south of Lake Ontario, whereas areas east of Lake Ontario will see highs in the mid to upper 70s.

Tonight, the surface low parent to the warm front will strengthen across the central Great Lakes and lift the warm front north of the region. This will then place the area beneath the warm sector, supporting ample warm moist air advection. Overall this will continue the chances for showers and thunderstorms, with the best likelihood for activity lying across the North Country due to the close proximity to the front.

A mid-level shortwave rippling through the zonal flow aloft and corresponding surface reflection (997-999mb low) passing to our west and northwest, will drag a cold front through the Lower Lakes on Sunday. Associated height falls with the pre-frontal trough will 'likely' encourage some measure of shower and thunderstorm activity ahead of this cold front. Guidance continues to suggest that the pre- frontal trough will arrive before the occurrence of peak heating between 12Z-15Z for far WNY
Even so
the cold front may still spark additional storms as it rolls east through the forecast area in the afternoon
Right now
the best chance for organized storms looks to be from the S. Tier/western Finger Lakes region ENE into the North Country and St. Lawrence Valley. Given ample shear (0-6km, 40 knots) any of the stronger cells will 'likely' have the potential to produce damaging winds and even an isolated tornado. SPC has highlighted the above mentioned areas in a slight risk for severe weather
storms will also be capable of producing torrential rainfall given PW values in the neighborhood of 1.75-2.00 inches.

Otherwise...outside of the convective activity it will become quite breezy, with wind gusts up to 45 mph. The strongest winds will be felt northeast of Lake Erie across the Niagara Frontier. Highs on Sunday will range from the upper 70s across the higher terrain to the low/mid 80s elsewhere.

Sunday night...with the departure of the cold front showers and thunderstorms will quickly decrease in coverage
there may still be some showers that linger east of Lake Ontario/St. Lawrence valley.

High pressure begins to build in on Monday with increasing subsidence which will bring about mainly dry weather for most locales. Although an isolated shower still can't be ruled out, especially east of Lake Ontario. The best part will be the notably cooler airmass and less humidity. Highs on Monday will be in the 70s near 80F in spots.

Surface high pressure slides overhead Monday night and then begins to sink south towards the Mid-Atlantic on Tuesday ahead of the next cold front. We should see mainly dry weather Tuesday before chances for showers and storms increase through Wednesday. More on that in the long term disco.

Confidence is low in timing and coverage of showers/thunderstorms associated with an approaching front for Tuesday night and Wednesday.
Long range guidance is in poor agreement on the evolution of a shortwave expected to slide east across Southern Ontario and the Great Lakes. Greater chances for showers and thunderstorms will potentially arrive Wednesday as a ~982mb surface low tracks across northern Quebec, sending its elongated cold front through the Northeast. While timing of this front and its associated prefrontal trough remain in question and thus lend lower confidence in how convection will ultimately unfold Wednesday...The system is expected to tap into a deeper plume of GOMEX-based moisture with PWATs potentially climbing to near 2" as it approaches. Thus, any storms that develop and move through the region should have the potential to bring locally heavy rains.

The primary cold front should move through the region Wednesday night, with increasing subsidence and a drier airmass allowing shower/thunderstorm chances to decrease from west to east in its wake. As much of the Northeast sits within the post-frontal airmass, temperatures will be notably cooler Thursday and Thursday night, with highs in the low/mid 70s and lows in the 50s and upper 40s respectively. Dry weather should then last through the end of the week with moderating temperatures as surface high pressure moves over and east of the region.

A frontal boundary across northern portions of the area will waver northward through tonight. While CIGS today north of the boundary (KART) will be mainly MVFR, all other terminals will be VFR south of the boundary. The main impact this afternoon will be the threat for convection, particularly east of Lake Ontario and along lake breeze boundaries. Chances for showers and thunderstorms will then continue throughout tonight inland from the lakes.


Sunday...VFR/MVFR. Showers and thunderstorms likely.
Monday...Mainly VFR. A chance for afternoon and evening thunderstorms inland from the lakes.
Tuesday...Mainly VFR conditions expected.
Tuesday night and Wednesday...MVFR/VFR with a chance for showers and thunderstorms.

Light winds and minimal wave action is expected to continue across the lower lakes today. There will still be the chance of afternoon showers and thunderstorms which could produce gusty winds and higher wave action.

A cold front will approach the region Sunday with increasing southwest winds which may bring a period of SCAs to area lakes. Northerly flow behind the front will then bring continued choppy conditions to the lakes through Monday. High pressure builds in late Monday with diminishing winds and waves for Tuesday.
