993 FXUS61 KBUF 170740 AFDBUF Area Forecast Discussion National Weather Service Buffalo NY 340 AM EDT Thu Apr 17 2025 .SYNOPSIS... High pressure will bring fair dry weather through tonight. A few showers will be possible Friday as a warm front works through the Lower Lakes. A better chance of showers and storms Friday night into the weekend. && .NEAR TERM /THROUGH FRIDAY/... Skies quickly clearing as high pressure builds into the Lower Lakes. We can look for mercury readings to drop to between 25F and 35F by sunrise. Sun-filled skies today which will help to push temps into the upper 40s to low/mid 50s. Tonight...fair dry weather. Lows mainly in the 30s. Increasing clouds Friday with a chance of a showers as a warm front crosses the Lower Lakes. Otherwise...much warmer with highs in the 60s east of Lake Ontario, to low to mid 70s elsewhere. && .SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/... Friday night through Saturday night a sharp mid level trough will move east across Ontario and Quebec. The strongest forcing from height falls and DPVA will remain north of the US/Canadian border, with more modest height falls and an associated surface cold front spreading across the eastern Great Lakes late Friday night through Saturday evening. Sufficient moisture and forcing along the advancing cold front will produce a few rounds of showers across the region, and there may be just enough instability to support a few widely scattered thunderstorms as well. The surface cold front will push south and east of the area late Saturday night, with showers tapering off from northwest to southeast. Surface high pressure will build from the upper Great Lakes Saturday night to the eastern Great Lakes Sunday, bringing a mainly dry second half of the weekend. && .LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/... Surface high pressure will drift slowly east across eastern NY and New England Sunday night, maintaining mainly dry weather as clouds increase ahead of the next system. A mid level closed low ejecting out of the 4-corners region this weekend will traverse the mid section of the nation, reaching the western Great Lakes Monday and then southern Quebec Tuesday. This system will capture a narrow plume of Gulf moisture, with forcing ahead of the mid level trough and associated cold front supporting a chance of showers again Monday through Monday night. Rain chances will decrease Tuesday through Wednesday, although lingering weak troughing across the Great Lakes and New England may still support a low chance of a few spotty showers. && .AVIATION /08Z THURSDAY THROUGH MONDAY/... Sunny skies with VFR across all terminals today. VFR will continue tonight. Outlook... Friday...VFR with a chance of a few showers. Friday night...VFR to MVFR with increasing chances of rain showers.
