Area Forecast Discussion National Weather Service Buffalo NY 1018 PM EDT Mon Jul 26 2021

SYNOPSIS. Weak high pressure will drift slowly across the eastern Great Lakes through tonight, with mainly dry weather outside of a few thunderstorms near the Saint Lawrence River this evening. There will be a better chance of showers and thunderstorms on Tuesday when a cold front will cross the region. Mainly dry weather will return Wednesday before another cold front brings a chance of showers and thunderstorms Thursday followed by cooler and less humid weather on Friday.

NEAR TERM /THROUGH TUESDAY NIGHT/. Satellite imagery shows mostly clear skies across western and north central NY. A few showers across Lewis county will depart late tonight.

Tonight, weak high pressure will continue to drift east into New England. A convectively augmented shortwave will move out of the central Great Lakes and into southern Ontario late tonight, with increasing clouds across our region late. Any rain associated with this feature will remain to our north and west through early Tuesday morning. Lows will range from the mid 60s on the Lake Plains to the upper 50s in the cooler Southern Tier valleys and Lewis County. There may be some patchy fog across the Southern Tier valleys and the Saint Lawrence Valley.

A cold front will drop across the region on Tuesday, with most model guidance showing at least some precipitation with this frontal passage. Timing is a bit early to take advantage of diurnally driven instability, which will be limited since cloud cover will move in ahead of the front. However most of the morning will be rainfree which will allow some instability to develop. Additionally, there will be a fair amount of mid-level wind shear with 700 mb winds increasing to 45 kts. This could support some stronger storms with both gusty winds and hail possible. SPC introduced a marginal risk for severe thunderstorms for most of our area. The time for the greatest risk would roughly be between 2 p.m. and 9 p.m. on Tuesday.

Frontal boundary will gradually push south and east of the area Tuesday night with showers and thunderstorms tapering off to showers late in the night. The front will also usher in cooler weather with lows ranging from the mid 50s to lower 60s. Some fog is also possible across the Southern Tier.

SHORT TERM /WEDNESDAY THROUGH WEDNESDAY NIGHT/. Surface high pressure will reside across western and north central NY Wednesday. A warm front will approach southwest NY through the day and a few showers and storms are possible in this area. Elsewhere, a majority of the region will be dry Wednesday. High temperatures will rise into the mid to upper 70s.

A warm front will track across the region Wednesday night. PWATs will rise however the highest moisture content will stay across the Ohio Valley into Thursday. Showers are possible mainly across western NY Wednesday night. Instability will increase Thursday while a shortwave trough approaches the region. The wind field will increase and showers and storms are possible through Thursday evening. Multiple areas of low pressure may develop on a cold front that will move through the region Thursday night. The added convergence and increase in moisture will keep the likelihood of showers and storms Thursday night. Cool northwest flow will filter into the region with 850mb temperatures falling to +6C by Friday morning. Daytime heating and steepening low- level lapse rates will allow for some showers to form. Lake enhancement might also increase shower chances through Friday afternoon.

LONG TERM /THURSDAY THROUGH MONDAY/. High pressure building across the region at the start of the period will maintain dry and cool conditions through most of Saturday. Low developing over western Ontario is forecast to approach the region bringing an increasing chance of showers and thunderstorms late Saturday into Sunday. The low's associated cold front will usher in a reinforcing shot of cooler air to start out the next work week.

Look for cool highs in the low to mid 70s on Saturday and Sunday before highs on Monday remain within a few degrees of 70s. Low temperatures Friday night will dip into the 40s across the interior sections of the southern tier and north country.

AVIATION /02Z TUESDAY THROUGH SATURDAY/. Mainly dry weather and VFR will prevail today as a weak area of high pressure and mid level dry air remains in place. VFR will continue to prevail in most areas tonight. Some patchy river valley fog will form across the Southern Tier late. Expect this will be less widespread than last night, with marginal confidence that it will build across KJHW.

Showers will spread across the region on Tuesday, but cloud bases should remain VFR through Tuesday morning. Cigs will fall to MVFR east of Lake Ontario (KART) Tuesday afternoon. Increasing chances of showers and possibly a thunderstorm Tuesday afternoon with localized MVFR/IFR possible.

Outlook .

Tuesday night . VFR prevailing, with a chance of showers and thunderstorms and associated brief/local CIG/VSBY restrictions. Wednesday . VFR. Thursday . VFR prevailing, with a chance of showers and thunderstorms and associated brief/local CIG/VSBY restrictions. Friday and Saturday . VFR.

MARINE. Weak high pressure will ridge from Ohio to Southern New England tonight, then a weak cold front will drop across the waters on Tuesday. Another high pressure system will build on on Wednesday. Winds will remain under 15 knots through Wednesday. A few thunderstorms are possible Tuesday with locally higher winds and waves.
