The near term models are in good general agreement through the period. A surface low northeast of Maine, and an upper level low over southwestern Maine will influence the weather through the period. These lows will curculate around one another as they go through the process of becoming vertically stacked. The upper low will bring colder air tonight, which will bringing some light snow to northern Maine overnight tonight. Mon mrng the upper low will move east of Maine into New Brunswick, a trough will extend west across central Maine. By the end of the period the surface and upper level low will be over the Gulf of Saint Lawrence, a trough will continue to extend west into central Maine. Loaded a blend to smooth out the minor differences in the models. Used NAM for Min temps/hrly temps through the overnight hrs it better reflected the colder temps both surface and aloft to support the wet snow across nrn Me. Loaded NAWAVE4 for seas in the coastal waters. Loaded windgust by factor tool.
