Area Forecast Discussion National Weather Service Buffalo NY 209 PM EDT Sun May 31 2020

SYNOPSIS. A weak trough will bring a few showers through this evening, then Monday will be mainly dry and a bit warmer as high pressure builds across Ohio. A warm front will arrive Tuesday, producing a few showers and bringing a return to warmer temperatures.

NEAR TERM /THROUGH MONDAY/. Troughing aloft and limited lake enhancement will result in some showers east of Lake Ontario this afternoon. These showers will weaken as they spread southward through this evening following the progression of a weak surface trough. Otherwise, temperatures will be on the cool side this afternoon, with temperatures in upper 50s to around 60 on the lake plains of Western NY, and mid 50s on the hills.

Any showers that develop will taper off overnight as the trough exits. Chilly northwest flow will support some lake effect and upslope clouds, especially southeast and east of Lake Ontario, with a clearing trend developing toward daybreak Monday as drier air moves into the eastern Great Lakes. Lows will drop into the mid 40s on the lake plains, and upper 30s in some of the colder Southern Tier valleys and east of Lake Ontario. It appears upslope clouds will linger too long across the typically colder areas to support much frost potential. Lewis county will likely be the coldest location, but even here clouds will limit frost potential.

High pressure across Ohio will ridge across the region on Monday, which will provide mainly dry weather for the day. The only exception is east of Lake Ontario where shortwaves embedded in an upper level trough will move across and will produce cloud cover and possibly a few showers Monday afternoon. Otherwise, Monday will be warmer with highs mainly in the 60s. A southwest gradient flow will be enhanced by a lake breeze, resulting in wind gusts to 35 mph northeast of Lake Erie on Monday afternoon.

SHORT TERM /MONDAY NIGHT THROUGH THURSDAY/. A warm front will push east through the western Great Lakes Monday night, before riding through the western Great Lakes Tuesday. As the front pushes eastward, warm air advection will allow for increased cloud cover and rain shower chances Monday night and Tuesday. Model guidances continue to show the upper level shortwave weakening. Resulting in a limited the amount of precipitation to fall in the eastern Great Lakes on Tuesday. Rain chances will continue Tuesday night and Wednesday as the frontal boundary lies across the eastern Great Lakes before sliding south.

Rain chances will begin to diminish Wednesday night from north to south. Surface high pressure will begin to build into the region which will begin to dry things out. Thursday.

Due to the warm air advection associated with the warm front, temperatures will continue to rebound back to normal. Highs are expected to climb into the mid and upper 60s Tuesday, whereas Wednesday and Thursday will rise up into the low to mid 70s.

LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/. High pressure overhead will keep conditions dry Friday. Weak low pressure and its associated cold front will cross the region Friday Night and early Saturday with the possible return of some showers/thunderstorms.

Warming trend to start the period with above normal highs in the upper 70s to low 80s.

AVIATION /18Z SUNDAY THROUGH FRIDAY/. Expect mainly VFR flight conditions for the 18Z TAF cycle. There will be some showers and steadier cloud cover east of Lake Ontario which may result in periods of MVFR flight conditions this afternoon at KART. A weak trough will drop southward through this evening with increasing cloud cover, but cloud bases will average 5-8k feet.

High pressure will build across Ohio and result in VFR flight conditions for Monday.

Outlook .

Monday night . Mainly VFR. Tuesday and Wednesday . Areas of MVFR with chance of showers. Thursday and Friday . Mainly VFR.

MARINE. A weak trough will then cross the eastern Great Lakes this evening. WSW winds will increase late this afternoon just ahead of this trough. Winds and waves will briefly approach Small Craft Advisory criteria at the east end of both lakes for a few hours late this afternoon and early this evening. Winds will quickly diminish overnight as the pressure gradient relaxes.

Yet another trough will cross the eastern Great Lakes Monday afternoon. WSW winds will increase ahead of this trough, especially on Lake Erie where winds and waves will get close to Small Craft Advisory criteria.

BUF WATCHES/WARNINGS/ADVISORIES. NY . None. MARINE . None.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
