Area Forecast Discussion National Weather Service Buffalo NY 650 AM EDT Thu Jun 20 2024

Muggy and hot again today with showers and thunderstorms, some of which could produce strong gusty winds and torrential downpours.
While temperatures will begin to moderate beginning Friday, real relief likely won't come until the beginning of next week.

Remnant MCV rolling through the northern part of the Niagara Frontier with heavy rain and lightning this morning. This complex of storms has weakened considerably from overnight with GOES-16 IR showing cloud tops warming
That said
will continue to keep an eye on it as convection could flair up again as it rolls ENE.

Otherwise...hot and muggy again today, all heat related advisory will remain in place for the entire forecast area
That said
the H598 ridge centered to our south will begin to sink southward and then become east to west oriented by Friday. We should see some cooling aloft today, with H850 shaving off a few degrees. This may be reflected in daytime temperatures of a degree or two.

As the ridge shifts position today, we should see more widespread convection inland from the lakes. Given PW values of 1.6-1.8 inches, weak flow, and small mbE vectors there will be the potential for flash flooding. This will especially be the case where storms have already moved over from previous convection this week. While 0-6km shear isn't all that impressive (20 knots), any stronger cells will also have the potential to produce damaging winds and some hail.

Summing it all up...SPC has placed our forecast area in a MRGL/SLGT risk for SVR weather today, and a MRGL risk for excessive rainfall.

Convection will linger into a portion of the night but with the loss of daytime heating coverage will likely decrease. Another muggy and mild night will be on-tap with lows only in the 60s to low 70s.

Friday, the frontal boundary will stall over the forecast area and continue to provide the opportunity for showers and thunderstorms with the best chance for showers toward the NY/PA line. High temperatures on Friday will be in the low 80s to near 90, on the northern side of the frontal boundary. If the front stalls farther north, then temperatures will be a bit warmer.

Warmer and more humid conditions return for the weekend as warm front moves north of the forecast area.

Friday night, the stalled front across the area will begin to slowly push north as a warm front late in the night and into the early Saturday morning. There should be a break in the shower/storm activity, especially with the lack of diurnal processes.
Showers/storms potential will then increase around daybreak Saturday as the front starts moving colliding with a ribbon of vorticity and area of increased moisture pushing towards the region. As of now, the best chance for showers early Saturday morning looks like it will lie across the North Country. Certainly can't rule out a shower or storm for the rest of the area as the warmth and humidity build back into the region.

Showers will expand in coverage across the entire area throughout the day Saturday as daytime heating increases, and as the sfc low (and its moisture) approaches the region. With the frontal boundary orientated from west to east, just to the north of Lake Ontario and into the North Country, the best chances for showers and storms will be lie along the front. Afternoon high temperatures will warm to the low 80s to low 90s across the area, with the cooler temperatures expected across the North Country with the warm front over/near the area.

The warm sector of the surface low to the north will be firmly in place for Saturday night continuing the potential for showers/storms across the entire area.

With the warm sector of the surface low to the north still in place for Sunday, showers/storms will continue across the entire area.
Showers will then increase from northwest to southeast across the area heading into the afternoon as a cold front approaches from the west. Warm and humid conditions will continue through Sunday as the warm sector remains in place ahead of the cold front.

The aforementioned cold front associated with the surface low passing to the north will cross the area on Sunday evening and overnight, causing more organized showers/storms to move through the area. A potent shortwave trough tracking across the area behind the passing front will continue the shower potential for Monday.

Increased ridging and an incoming surface high will result in drier conditions for Monday night through most of the rest of the period, though some guidance does bring some showers back into the region for mid-week.

Temperatures will be well above normal for Sunday with highs in the low 80s to near 90. Temperatures cool behind the passing cold front to the mid 70s to low 80s for Monday before warming again for Tuesday & Wednesday back to the low to upper 80s.

Mainly VFR at area terminals today. Areal coverage of showers and storms will be greater today, with a risk of very heavy rain and gusty winds.

Tonight...VFR conditions outside of showers and storms. Once again there will be the potential for some fog in the river valleys of the S. Tier.

Friday and Saturday...Mainly VFR, but a chance for mainly afternoon and evening thunderstorms inland from the lakes.
Sunday...VFR/MVFR. Showers and thunderstorms likely.
Monday...Mainly VFR, but a chance for afternoon and evening thunderstorms inland from the lakes.

A generally quiet period is expected for the lower Great Lakes through the rest of the week and into the weekend as a large upper-level ridge remains across the eastern CONUS, resulting in a lighter surface flow. Only concern will be in the afternoon and early evening hours as showers and thunderstorms could produce higher wind gusts and waves.

The heat will continue today. Below are record high temperatures for our three main climate sites:
