Area Forecast Discussion National Weather Service Buffalo NY 800 AM EDT Thu May 13 2021

SYNOPSIS. An expansive area of high pressure will take up residence over the Great Lakes through early next week with an extended period of dry weather. Temperatures will continue to trend warmer each day, with well above normal temperatures arriving by early next week.

NEAR TERM /THROUGH FRIDAY NIGHT/. A large area of high pressure . centered over the mid western states . will remain in place through the period. Rain free weather is assured with temperatures moderating back towards normal mid May levels. The only issue could be some patchy frost tonight in the chillier areas of the Srn Tier.

SHORT TERM /SATURDAY THROUGH SATURDAY NIGHT/. Surface ridging will tend to maintain influence through this period. Weak upper wave swings through Saturday and combines with diurnal heating to potentially bring some isolated afternoon showers well inland from the lakes.

LONG TERM /SUNDAY THROUGH WEDNESDAY/. Weak shortwave passing through Sunday could bring a pop up shower Sunday afternoon well inland from the lakes, otherwise the expectation is that Sunday will be dry.

Somewhat better chances for showers arrive early next week as high pressure shifts off to our east allowing for moisture to return into the area. Not much trigger other than diurnal heating, therefore probably only looking scattered activity at best with more periods of dry weather.

Daily high temperatures look to be in the upper 60s to mid 70s.

AVIATION /12Z THURSDAY THROUGH MONDAY/. High pressure surface and aloft over the Upper Great Lakes will drift slowly eastward through tonight, with VFR prevailing. Diurnal cumulus will develop during the midday and afternoon well inland from Lake Erie and Ontario with VFR bases.

Outlook .

Friday through Monday . VFR.

MARINE. Gentle to moderate breezes will be in place across the Lower Great Lakes through Friday night . maintaining negligible waves. The choppiest conditions during this period will be over the eastern basin of Lake Ontario.

Looking further ahead to the upcoming weekend . high pressure over the region will guarantee fair weather with generally light winds and little wave action.

BUF WATCHES/WARNINGS/ADVISORIES. NY . Frost Advisory until 8 AM EDT this morning for NYZ006>008-012- 019>021-085. MARINE . None.
