Area Forecast Discussion National Weather Service Buffalo NY 235 AM EDT Wed May 27 2020

SYNOPSIS. Expect warm and humid conditions through late week. Just a few showers and thunderstorms will be possible this afternoon, mostly along lake breeze boundaries south and east of Lake Ontario, as well as the higher terrain across the Tug Hill and western Dacks. A period of more widespread showers and thunderstorms will occur later this week as a warm front moves through on Thursday, followed by a cold front on Friday. Strong Canadian high pressure will then build across the region in the wake of the cold front, providing mainly dry and refreshingly cooler weather for the weekend.

NEAR TERM /THROUGH TODAY/. Just some patches of high thin cirrus clouds passing south to north across western NY through the remainder of the overnight. Otherwise, warm and sultry conditions on tap with lows bottoming out in the mid and upper 60s by daybreak as high pressure remains in control.

For today, indications are there will be a minimum in showers and thunderstorm coverage. Greatest potential would be over the northern Niagara Frontier to the west of Rochester and also over the Eastern Lake Ontario region. As heights slightly relax compared to yesterday and temps aloft come down slightly, high temps today should be a few degrees lower in the middle to upper 80s instead of upper 80s to around 90F.

SHORT TERM /TONIGHT THROUGH SATURDAY/. Dry weather expected area wide Wednesday night as high pressure remains in control. Lows Wednesday night will fall back into the lower to mid 60s.

Return flow will bring increasing chances for showers and some thunderstorms to the region on Thursday as ridge aloft slides farther east and moisture from Gulf of Mexico surges northward. Plan on increasing coverage with daytime heating on Thursday afternoon. Given presence of larger scale synoptic lift, coverage of showers and thunderstorms looks to be greater on Thursday than what will be occurring through Wednesday afternoon. High temperatures on Thursday mainly in the upper 70s to lower 80s will be tempered by more cloud cover and better chance of rain.

Despite the lack of any real trigger Thursday night, with deep moisture in place won't take much to pop off some scattered showers/isolated storm. Expect warm and sultry conditions Thursday night out ahead of approaching cold front as it pushes into the central Great Lakes by early Friday morning. Lows will only fall back into the mid and upper 60s, with some spots possibly not getting below 70F.

The most active day of the week still looks to come on Friday as stronger mid-level height falls and strong cold front plows across the region. This will not only bring a period of showers and storms along and ahead of the front, it will also be the leading edge of some much cooler, drier air that will build across the area heading into the weekend. On Friday, real push of cooler air will lag behind the boundary, so one more day of warm and humid conditions, with highs in the upper 70s and lower 80s.

Some rain showers will linger Friday night, but by late evening most areas will be drying out in the wake of the cold frontal passage. Secondary cold front pushes through the region late Friday night and Saturday morning. This will usher in real push of much cooler and much drier air across the region. Any lingering light rain showers across eastern areas Saturday morning with be few and far between and will taper off from west to east through the early afternoon. Highs on Saturday will be back below normal in the middle to upper 60s.

LONG TERM /SATURDAY NIGHT THROUGH TUESDAY/. . Below Normal Temperatures Through the Period .

An expansive Canadian sfc high will provide us with fair cool weather through Monday. A complex frontal system will offer the potential for some showers on Tuesday. Warmer weather will be guaranteed for the remainder of the week.

AVIATION /07Z WEDNESDAY THROUGH SUNDAY/. VFR conditions through the TAF period with only a minimal risk for a few showers or few thunderstorms for the counties lining the south shore of Lake Ontario, as well as across the Eastern Lake Ontario region inland from the lakeshores this afternoon. KROC has the best chance of being impacted, with nothing worse than low VFR CIGS during this time. An isolated heavier shower could briefly reduce VSBY to MVFR as well. Otherwise, outside of any diurnally driven lower clouds during heat of the day, just a general increase in mid and upper level cloud decks can be expected through this afternoon and evening.

Outlook .

Thursday . VFR to MVFR with scattered showers and thunderstorms. Friday . Showers and thunderstorms likely. Saturday . VFR.

MARINE. A weak pressure gradient will remain in place across the lower Great Lakes through Thursday with light winds and minimal wave action. The weak gradient will allow for onshore breezes to develop during the afternoon hours. Southwest winds will freshen Friday then shift to the northwest into Saturday as a cold front crosses the region.

The light winds and a humid airmass will result in areas of dense fog on Lake Ontario at times through late this week. The risk of fog will not diminish until later Friday into Saturday as less humid air arrives.

CLIMATE. A very warm airmass will remain in place across the region through today. Below are the record highs and record warm minimum temperatures for today, the 27th of May. Since we are now in Eastern Daylight Time (EDT), the climatic day runs from 1 AM EDT to 1 AM EDT.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
