Area Forecast Discussion National Weather Service Buffalo NY 755 AM EDT Sun Jun 13 2021

SYNOPSIS. Some showers or a thunderstorm will be possible today and again on Monday. Surface high pressure builds into the region Tuesday with cooler and drier weather through Thursday. Chances for showers return towards the tail end of the week.

NEAR TERM /THROUGH TONIGHT/. Weak mid-level shortwave driving convective showers this morning will once again drive convection later this afternoon into the evening hours. However, due its early arrival across our forecast area coverage looks like it will be fairly sparse. 00Z/13Z guidance continues to support this idea with the best chance for storms over the interior sections of the Southern Tier towards Lewis County. Isolated convection will still be possible elsewhere but likely well away from the lakes. What convection does form will only have about 30 kts of shear on northwesterly flow aloft and 1000-1500 J/kg of MUCAPE. SPC has place our forecast area in a Marginal risk, with a Slight Risk over southeast part of Allegany County for a severe storm.

Tonight, convection will likely weaken and then diminish in coverage before more storms fire up on Monday. More on that in the short term disco. Otherwise, lows temps will be in the 50s to low 60s.

SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/. A shortwave trough over Northwestern Ontario Monday morning will sharpen as it tracks east into northern New England by Monday night. Showers and possibly a thunderstorm are possible in the morning across western NY as the trough tracks towards the region. Daytime heating and steepening lapse rates will increase the risk of showers and thunderstorms in the afternoon and evening. Most favorable diurnal timing will be near central New York and the St Lawrence Valley. There again appears to be a small risk for strong to severe storms with the shortwave providing some wind shear to support organized convection. The main limiting factor is that the air mass will be lest moist (precipitable water values around 1 inch) and more stable before the passage of the trough.

A cold front will move across the region late Monday night into Tuesday. This will produce a few showers, but more notably it will usher in much cooler air into the region. A trough will settle across the region Tuesday into Tuesday night. This will begin a period of below normal temperatures into mid-week.

High temperatures will rise into the mid to upper 70s Monday, falling to the 50s Monday night. High temperatures Tuesday will be slightly below normal with highs in the low to mid 70s, falling to the mid 40s to low 50s Tuesday night.

LONG TERM /WEDNESDAY THROUGH SATURDAY/. An expansive area of surface high pressure will build across the Great Lakes which will create quiet weather through at least Thursday night. Temperatures Wednesday will be on the cooler side with highs in the upper 60s and low 70s. Temperatures Thursday will begin to rebound back into a range of 70s due to southwesterly flow.

The next significant system will be associated with a mid-level trough which will make its way across the Upper Great Lakes Friday. As it appears now, model consensus has surface low and frontal boundaries associated with the mid-level trough to arrive to the Lower Great Lakes late Friday, finishing its sweep across the area Saturday. Therefore, Friday should start of dry with increasing chances later in the day. Showers and thunderstorms will most likely move through Friday night, with lingering showers on Saturday when the trough axis moves across the region.

Otherwise, the warming trend will continue Friday with highs making their ways into upper 70s to low 80s. With the frontal passage Friday night, highs will be a tad cooler with highs in the 70s.

AVIATION /12Z SUNDAY THROUGH THURSDAY/. VFR will then likely rule through the majority of the morning hours, if not longer. A few afternoon showers or a stronger storm will then be possible which may bring about localized IFR/MVFR conditions. However, coverage is expected to be too sparse to add it to the TAFS for now. It's likely most storms will develop well east of our TAF sites across portions of the S. Tier northeast into the Finger Lakes region.

Tonight, any storms that do form will weaken and dissipate overnight with VFR anticipated at all terminals.

Outlook .

Monday . Mainly VFR. A chance of showers and thunderstorms. Tuesday . Mainly VFR. A chance of showers. Wednesday and Thursday . Mainly VFR.

MARINE. A weak surface trough will gradually move across the eastern Great Lakes today, but winds will not pick up much until Monday following its passage. This will produce some chop, with conditions expected to approach but likely fall short of small craft criteria on Monday.
