| Area Forecast Discussion National Weather Service Buffalo NY 217am EDT Sunday April 5 2026 .WHAT HAS CHANGED... No significant changes with this forecast package. .KEY MESSAGES... 1) Much cooler today, brisk with scattered showers. 2) Accumulating snow starting Sunday night, highlighting Monday night into Tuesday morning for greatest accumulation. KEY MESSAGE 1...Much cooler today, brisk with scattered showers. A cold front, and associated showers, will exit our region early this Easter morning. Strong cold air advection will hold temperatures steady, or slightly lower them through the day. Within the cold air advection, increasing mixing heigheights and a still tight pressure gradient will allow for a 40 knot LLJ around 2K feet to mix down, with southwest winds gusting 35 to 45 mph. These winds, peaking this afternoon, will slowly diminish to under 25 mph by Monday morning. Lift ahead of a second shortwave trough and the passage of a secondary surface cold front this afternoon, will bring additional light showers through the afternoon hours, that may mix with a little snow within the strong cold air advection. KEY MESSAGE 2...Accumulating snow starting Sunday night, highlighting Monday night into Tuesday morning for greatest accumulation. Temperatures at 850 hPa will drop to around -8 to -9C Sunday night and into Monday, and then down to -13 to -15C Tuesday with the passage of a second shortwave trough within the mean mid level flow. Any snow accumulation through Monday will be minor and mainly reserved for the higher terrain. By Monday night, with the passage of the second shortwave trough, and temperatures below freezing across the region, falling snow will be able to accumulate with NBM profiles depicting one to two inches across our region, with up to 4 inches on the hill tops of SW NYS through Tuesday morning. Accumulating snow will end by late Tuesday morning behind the shortwave trough and solar effects of a strong April sun angle. Highs Tuesday are expected to be some 15 to 20 degrees below normal. Marine Behind a cold front passage this morning, strong cold air advection and a still tight surface pressure gradient will bring increasing winds and waves to the eastern Great Lakes. Winds and waves are likely to diminish below small craft criteria, this evening on the ice free waters of Lake Erie, while not till later tonight and Monday morning on Lake Ontario. The strong southwest to west flow will also bring small craft winds to both the Niagara and Saint Lawrence River today. Strong northerly flow behind a mid level shortwave trough will bring elevated winds and waves, especially to Lake Ontario late Monday night and into Tuesday, with SCA (Small Craft Advisory) again likely. Hydrology A Flood Advisory remains in effect for the Salmon River in northern Oswego County. High flows will continue as water is released from the Salmon River Reservoir due to runoff from recent heavy rain and snowmelt. The water expected water levels will not produce any significant flooding, but will continue to produce minor flooding in low lying areas along the creek and create dangerous currents. Fisherman should avoid the river until flows subside. A cold front will cross the area this morning, producing another round of soaking rainfall. The rain will result in minor ponding of water in poor drainage areas and within-bank rises on area creeks and rivers, but is not expected to be enough to produce any more impactful flooding. NOAA Buffalo NY Office: Watches - Warnings - Advisories NY...Wind Advisory until 4am EDT early this morning for NYZ007-008. Marine Small Craft Advisory from 8am this morning to 10pm EDT this evening for LEZ020-040-041. Small Craft Advisory from 8am this morning to 10pm EDT this evening for LOZ030.
