Area Forecast Discussion National Weather Service Buffalo NY 648 AM EDT Wed May 8 2024
SYNOPSIS
A warm front will move across the area, with showers and a few thunderstorms ending across western and north central NY this morning. Dry weather will then prevail most of the time for the rest of today, although a few more showers and thunderstorms are possible later in the afternoon and evening, especially east of Lake Ontario. Unsettled weather will then last Thursday through the weekend with a series of low pressure systems crossing the region.
NEAR TERM /THROUGH TONIGHT/
Regional radar shows showers across western and north central NY this morning. Warm conditions with temperatures in the upper 50s to mid 60s. In fact, some places are about 20-25 degrees warmer than 24 hours ago (Tuesday morning.) Breezy, southwest winds have arrived along the Lake Erie shoreline into Buffalo with gusts 30-40mph.
A stacked area of low pressure is across northern Lower Michigan this morning. A warm front extends from the northern shores of Georgian Bay to central NY, bisecting Lake Ontario while a cold front is moving into far western NY. A 40kt low level jet is across the Lower Great Lakes and Ohio Valley with elevated instability across most of western and central NY.
While the chance for thunderstorms is dwindling, it's still possible ahead of the cold front this morning. Well-aligned low level winds have allowed gusty winds to mix to the surface behind the cold front this morning. The warm, moist airmass across the relatively cold Lake Erie waters may result in patchy fog inland from Lake Erie through mid- morning.
The warm front will move into the Lake Ontario region while a cold front continues to move across western NY this morning. This will usher in drier air and as showers and possible thunderstorms move into north central NY, activity will end from west to east across western NY this morning. The environment is less favorable east of Lake Ontario this morning so thunderstorm potential will decrease. By early afternoon, the area of low pressure will move into eastern Ontario and the warm front will be near the Saint Lawrence Valley. Mostly dry and breezy conditions will be across the forecast area. In fact, southwest winds with gusts up to 35 mph are possible across western NY.
A secondary shortwave trough will move across northern NY this afternoon. Another round of showers and thunderstorms are possible mainly east of Lake Ontario but also along a convergence zone south of Lake Ontario. Most of the region will be post-frontal with low chances of thunderstorms, however greater instability will be just to the southeast of the forecast area and coupled with a strong wind field, there may be a few stronger storms across Oswego and Lewis counties late this afternoon into this evening.
The shortwave trough will move east of the region tonight and showers and any thunderstorms will diminish and move east of the region. Dry conditions are expected across the forecast area overnight.
SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/
An elongated mid level trough will remain in place Thursday through Thursday night from the Canadian Maritimes to the Great Lakes, with an east-west oriented frontal zone stretching from the Ohio Valley to the Mid Atlantic. Latest model guidance has continued the southward trend in the frontal position, with a wave of low pressure moving east along the boundary now taking a farther south track Thursday through Thursday night. The farther south track will yield a much improved forecast for Thursday, with mainly dry weather expected through at least the first half of the day. Deeper moisture and frontogenesis will gradually increase from southwest to northeast as the frontal wave moves across PA, bringing increasing chances of showers in the afternoon for areas south of Lake Ontario.
Rain chances will continue Thursday night as another wave of low pressure moves east along the front. The best chance of more widespread rain will be found from the Southern Tier into Central NY in closer proximity to deeper moisture and forcing, with rain chances trending lower for areas close to the Canadian border.
Friday through Friday night, the longwave trough will continue to carve out over the eastern US as a series of shortwaves dig through the Great Lakes and New England. DPVA and height falls will maintain an area of forcing and rain downstream of the trough axis, with a weak surface low developing in response to the forcing aloft over PA and the Mid Atlantic. The GFS continues to be the farthest north with this feature and would produce widespread rain across the region. The NAM/GEM/ECMWF have all trended farther southeast, keeping the best chance of organized rain from the Finger Lakes into Central and Eastern NY, with lower rain chances in our region.
Trended POPS and QPF down for Friday through Friday night, especially for areas near the Canadian border.
Temperatures will be notably cooler Thursday through Friday as persistent low level northeast flow funnels cooler air out of Canada.
LONG TERM /SATURDAY THROUGH TUESDAY/
Overall, the pattern will remain unsettled over the weekend through early next week, although the finer synoptic scale day to day details remain uncertain. A deep mid level trough from the Great Lakes to New England over the weekend will gradually deamplify early next week, although shortwaves will continue to traverse the US/Canadian border.
Saturday should start mainly dry, with one system moving east off the New England coast and the next moving through the central Great Lakes. The upstream shortwave and associated surface low will then move over or just south of the region Saturday afternoon through Saturday night, with another round of showers. The trough axis will gradually move off the New England coast Sunday, with rain chances trending down from west to east. Temperatures will remain quite cool over the weekend with clouds and cool temperatures aloft. Highs both days will reach the 55-60 degree range in most areas.
Monday through Tuesday another shortwave will move from the Great Lakes into New England, maintaining a chance of a few showers.
Temperatures aloft will start to recover as mid level heights gradually rise, allowing temperatures to trend to near or a little above average by Tuesday.
AVIATION /10Z WEDNESDAY THROUGH SUNDAY/
An area of showers and a few embedded thunderstorms resides across western and north central NY this morning. A brief period of IFR conditions with heavy rain and lightning is the main concern with any thunderstorms this morning. Prevailing VFR conditions will deteriorate to MVFR/IFR this morning as a warm front moves through the region. The main concern will be lowering ceilings, however fog may develop on Lake Erie and move onshore by 15z.
Confidence is low to medium that the fog will reach KBUF before winds ramp up this morning.
Flight conditions will improve to VFR from west to east across the region today. As mentioned above, winds will ramp up and southwest winds 15-25kts with gusts up to 30kts are possible late this morning through early this afternoon from KIAG to KROC. Another round of showers and a few thunderstorms are possible east-southeast of Lake Ontario this afternoon into the evening. Flight conditions will worsen from north to south tonight with MVFR/IFR conditions at KART by 00z and at KROC/KBUF by 6z tonight.
Outlook...
Thursday and Friday...Mainly MVFR. Showers likely and MVFR stratus.
Saturday and Sunday...VFR/MVFR. A chance of showers.
MARINE
WSW winds will then increase today, particularly across Lake Erie...where winds and wave action will be sufficient to support Small Craft Advisories as outlined below
Elsewhere choppy
but sub- advisory conditions can be expected.
An increasingly moist airmass crossing the cold lake waters will likely produce marine layer fog this morning on Lake Erie and Lake Ontario with visibility restrictions.

NY...None.

Small Craft Advisory until 11 PM EDT this evening for LEZ040-041.
