-- Changed Discussion --
High pressure crests over the area Saturday night with temperatures dropping quickly until just after midnight when higher clouds arrive and thicken for the rest of the night. Expect upper 40s north and low to mid 50s south. The clouds will thicken through the day on Sunday with highs in the 70s and low humidity. Showers will likely break out in the northwest portion of the state later in the afternoon and have increased pops to reflect this expectation. On Sunday night, a warm front will cross the area with a deepening low in Quebec. Most of the precip will be with the warm front and some elevated convection is possible. Have not added isolated thunderstorms at this time, but will have to continue evaluating the situation. The warm front will bring more humid conditions for Monday ahead of a cold front which will sag southward through the day. Will continue going with chance pops for showers on Monday with no thunderstorms as the upper trough should push east before peak afternoon heating.

&& .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
-- Changed Discussion --
High pressure builds Monday night and Tuesday with dry conditions and lower humidity. Temperatures will continue mild Tuesday, but guidance is now indicating a stronger system for later Tuesday night and Wednesday which resulted in increased pops for Tuesday night and Wednesday and fall-like temperatures for late week. Will continue with MOS temps for late week rather than going with the colder deterministic solutions on temps.

Embedded thunderstorms are possible Sunday night. VFR returns Monday afternoon into Tuesday night. Another frontal system will likely bring MVFR conditions late Tuesday night into Wednesday with a chance of some IFR cigs.

NEAR TERM: Winds and seas will remain below SCA criteria through Saturday. SHORT TERM: Areas of fog are possible on the waters later Sunday night into Monday ahead of a cold front. An SCA is possible Wednesday due to both long period south swell and winds. SCAs may also be possible late next week as the first fall-like air mass arrives.
