Key Message 1...Scattered showers and thunderstorms through tonight, followed by periodic chances for showers and storms through midweek, although plenty of dry time can be expected. Area of convection essentially tied to a MCV (Mesoscale Cyclonic Vortice, a low-pressure center in a group of thunderstorms, that pulls winds into a circling pattern, or vortex) currently pushing east across far northern Pennsylvania. This feature will exit the region by late this afternoon. Although there may be a Probability of Precipitation up shower or storm on the periphery of the MCV, mainly dry weather is expected this afternoon. A cold front will push south across western and north-central New York tonight. Moderate shear and a moist airmass will remain in place within the warm sector ahead of the boundary, however loss of daytime heating will result in less instability. The potential for severe weather appears low, but scattered showers and storms will be possible as the boundary pushes south through the region. Potential for localized heavy rainfall remains in place within the moist airmass. The cold front will stall just to our south tonight, then remain nearly stationary through midweek. Drier air will reside to the north of the boundary, with the main threat of showers and a few storms toward the western Southern Tier Tuesday through Wednesday closer to the frontal boundary, and mainly dry weather elsewhere. Marine West to southwest flow will increase through this evening as the pressure gradient tightens ahead of an approaching cold front. Winds of around 15 knots are expected on Lake Ontario, bringing choppy conditions, but expected to remain below SCA (Small Craft Advisory) criteria. 15 to 18 knot winds and 2 to 4 foot waves are expected on Lake Erie, with small craft headlines remaining in place through this evening. The cold front crosses the lower Great Lakes tonight with winds veering west to northwest and diminishing to 10 knots or less, although 12-15 knot northwesterlies will continue across eastern Lake Ontario through tonight. Scattered thunderstorms will also be possible on both Lake Erie and Lake Ontario through this evening, with a few stronger storms possible that will be capable of producing strong winds and locally higher waves. Winds of 10 knots or less are then expected for Tuesday through Wednesday. NOAA Buffalo NY Office: Watches - Warnings - Advisories NY...None. Marine Small Craft Advisory until 11pm EDT this evening for LEZ040- 041. |
