With only additional light precipitation today between 0.25 and 0.5 inches in the next 24 hours, flooding concerns decrease tonight for these locations. However, ponding of water on roadways and high river flows could continue into the overnight hours tonight. KEY MESSAGE 2... Thursday is looking to be a dreary day in store with overcast skies and medium to high (60-80%) chances for precipitation as our next weather system moves through eastern New York and western New England. The current forecast supports the precipitation type to be rain for most of eastern New York and western New England as temperatures stay above freezing. Locations for this exception are across the southern Adirondacks and high terrain of the southern Greens, where light freezing rain, then a light mix of rain and snow can occur Wednesday night into Thursday morning. Ice accumulations with this morning forecast has increased to range between 0.1 inches and 0.25 inches across the highest terrain locations in southern Vermont. For the southern Adirondacks, ice accumulations continue to range between 0.01 inches and 0.1 inches. This could lead to a few slick spots on non-pavement surfaces in the southwestern Adirondacks and highest terrain locations of the southern Greens Thursday morning.Temperatures gradually rise late Thursday morning to above freezing for precipitation to change over to plain rain. Precipitation chances decrease Thursday night to less than 60%. With the latest forecast supporting light precipitation amounts less a quarter inch, confidence continues to increase for no significant flooding impacts to occur for Thursday. KEY MESSAGE 3... For this weekend, medium to high chances for precipitation return after a brief break on Friday. Flooding concerns at this forecast time are low as precipitation is looking to be light Saturday into Sunday. With low temperatures above freezing and high temperatures in the 50s and 70s, precipitation type will be rain this weekend. Latest ensemble forecast model guidances are supporting for Saturday to be isolated to scattered rain showers with breaks of sunshine during the afternoon hours. Sunday afternoon is shaping up to be widespread rain showers, but confidence is low if breaks in the precipitation occurs. && .AVIATION /12Z WEDNESDAY THROUGH SUNDAY/...
