| Area Forecast Discussion National Weather Service Buffalo NY 1040am EDT Fri April 26 2024 Synopsis Canadian high pressure over eastern New York and western New England will slide east to the New England coastline today, providing us with a fine spring day to close out the work week. Temperatures will warm into the upper 50s and 60s as a return flow of milder air develops around the departing high. The warming trend will continue this weekend and into early next week, resulting in late spring to summerlike warmth both Sunday and Monday. While there will also be a few showers and thunderstorms around, particularly during Saturday, a fair amount of dry time can also be expected. A cold front will then bring our next chance for more widespread showers and a few thunderstorms as it crosses our region Monday night and Tuesday. Near Term - Until 6am Saturday Morning Canadian high pressure over eastern New York and western New England will drift east to the New England coastline today, while keeping fair dry weather across our region. While there could be some thin/spotty high clouds, as well as very some limited afternoon diurnal cumulus across far western New York, these will not mar what will again be abundant amounts of sunshine. With a return flow of milder air setting up on the backside of the departing high, temps will rebound with highs climbing back to the upper 50s across the North Country and to the lower to mid 60s elsewhere. This said, an ENE flow off Lake Ontario will help to keep temps along the south shore of that lake confined to the 50s. Tonight the surface high will remain anchored just offshore of the New England coast,while sharp upper-level ridging builds across New York State. Meanwhile further west, an initial cutter-type low will weaken as it tracks from the central Plains states to the Upper Mississippi Valley. As it does so, this system will push its attendant warm front east toward our region, where it will run smack up against the strong ridging that we'll have in place aloft. With this in mind, it comes as no surprise that the guidance suite continues to trend slower and weaker with the approaching front, with this feature now appearing to advance east slowly enough to merely bring a general west-east in mid and high cloud cover to most areas tonight, with perhaps the chance of a shower reaching Chautauqua county late. Otherwise the night should remain dry, and will feature considerably milder temperatures than the previous couple nigheights as a southeasterly return flow of milder air strengthens across our region. Expect lows to range from the upper 30s across the North Country to near 50 along the Lake Erie shoreline, where downsloping will provide an added boost to temps, and may also allow winds to gust to 30-35 mph during the second half of the night. Short Term - 6am Saturday Morning Through Sunday Night An upper level trough will dig across the Northern Plains, with a series of diffuse surface lows forecast to track to our north and west during the weekend. A warm front extending from the the first wave of low pressure will move across our region from southwest to northeast on Saturday. The front will weaken late Saturday as it gets further from the surface low. This front will likely bring some showers to the region on Saturday, but the day should be far from a washout. The day will be mostly cloudy with a few hours of showers in some spots, but otherwise warmer with highs in the upper 50s to upper 60s with the warmest locations downwind of the Chautauqua Ridge near the Lake Erie shoreline. Southerly flow will maintain above normal temperatures throughout the weekend. 850mb warm up to +12/13 C which will support high temperatures well above normal in the 70s to lower 80s on Sunday. The combination of the warmer temperatures and the lingering synoptic lift from the lingering/stalled cold front to the north of the area, will support diurnally driven instability and afternoon showers/thunderstorms. A mid-level ridge axis will cross the area Sunday night supporting dry weather Sunday night. Long Term - Monday Through Thursday Departing upper level ridge will maintain mainly rain-free weather for Monday, with only a slight chance of an instability shower or thunderstorm. Monday will almost feel summer-like with highs reaching 80F at many locations. Low pressure tracking across the central Great Lakes and into Ontario province will push a cold front across the region on Tuesday. Warm and moist air mass in place will result in ample instability to support thunderstorms with the frontal passage, especially Tuesday afternoon and early evening. After this, forecast confidence decreases with a wider range in the way model guidance handles a series of weak frontal boundaries. In general there's a small chance of showers Wednesday and Thursday, focused during afternoon/evening hours corresponding to diurnal heating. It will be a bit cooler, but temperatures will still remain above normal during this time. Marine Canadian high pressure across eastern New York and western New England will slide further east to the New England coastline today, with a general easterly to northeasterly flow continuing across the lower Great Lakes. On Lake Ontario, winds will be more easterly, and will become strong enough to bring advisory-level conditions to the portions of the lake west of Rochester this afternoon and evening. Meanwhile on Lake Erie, winds will back to northeasterly and increase to 10-15 knots once again, resulting in the redevelopment of a moderate chop. Tonight and Saturday, the high will remain anchored off the New England coast, while low pressure tracks from the central Plains to central Ontario. This will result in winds across the Lower Lakes veering to southeast and then south while strengthening later tonight into Saturday, though the increasingly offshore nature of the flow will help to direct the greatest wave action across Canadian waters. As a result, conditions are expected to remain below advisory criteria. NOAA Buffalo NY Office: Watches - Warnings - Advisories NY...None. Marine Small Craft Advisory until 11pm EDT this evening for LOZ042. |
