| Area Forecast Discussion National Weather Service Buffalo NY 546am EDT Monday April 27 2026 .WHAT HAS CHANGED... No significant changes with this forecast update. .KEY MESSAGES... 1) Unsettled weather returns Tuesday, then begins turning cooler Wednesday and last through the rest of the week. KEY MESSAGE 1...Unsettled weather returns Tuesday, then begins turning cooler Wednesday and last through the rest of the week. High pressure will support fine spring weather across the entire Lower Lakes region today. As the ridge drifts to our east we will see return southerly flow develop and pick-up across the area. This will help to boost afternoon temperatures well into 60s to low 70s. A deepening low pressure system over the Midwest region will track northeast tonight into the upper Great Lakes. A vigorous low-level jet ( +50 knots) with this system will arrive across our region late tonight and early Tuesday morning. Given south to southeast flow, there is the potential that we could see some gusty downslope winds (45-50 mph), especially across the higher terrain south of Rochester/Buffalo and off the Chautauqua ridge. With the arrival of the front, expect some measure of showers Tuesday and even a few rumbles of thunder can't be ruled out. As was noted...as the front moves east into the Finger Lakes region and North Country the LLJ weakens and with overall lack of instability will limit shower coverage. A brief lull or gap in precipitation chances develops Tuesday night ahead of the next potentially soaking rainfall. That's not to say we will be precipitation free just less in terms of shower coverage. Attention turns to an area of low pressure tracking ENE across the Ohio Valley Wednesday. Given advertised favorable jet dynamics (right entrance region) and deep moisture streaming north across the area (PW values (Precipitable Water values) 1-1.10") we could see another soaking rainfall across the region. With the departure of the low Wednesday evening its cold front will sweep across the region with a much colder airmass spilling in across the Lower Lakes. In fact, 850 T's are expected to tumble to -3C to -6C behind the cold front beginning Wednesday night. A slow lumbering closed low will then maintain a chilly cyclonic flow across the region the rest of the week into the weekend. Temperatures both Thursday and Friday will be unseasonably cool with highs expected in the 40s to right around 50F. We are 'likely' to not see much improvement temperature wise until Sunday or until early next week. Marine Surface high pressure over the eastern Great Lakes region will slowly exit off to our east today. Expect mainly light winds and wave action for much of the day, with some chop developing on the western end of Lake Ontario by late this afternoon. South to southeast winds strengthen tonight into Tuesday, which will support small craft conditions but the higher wave heigheights will remain in the Canadian waters. Low pressure over the Ohio Valley will approach the area Wednesday and then send its cold front through the lakes Wednesday night. With the frontal passage expect strengthening west to northwest flow which will likely support another round of small craft conditions that lasts through much of the week.
