-- Changed Discussion --

&& .NEAR TERM /THROUGH MONDAY NIGHT/...
-- Changed Discussion --
A slow moving cold front continues to push southwards into the forecast area today, bringing rain showers into the northern half of the forecast area. With the overcast skies of the day, thunderstorm chances are isolated to scattered, with the best chance for storms being anywhere which has experienced clearing late this afternoon. Downeast areas have remained mostly clear but influence from the marine layer combined with lack of a lifting mechanism has left this area mostly dry so far, with a chance for some scattered showers and storms to develop by early this evening. Any storms that do develop will have the potential to bring gusty winds with a building LLJ aloft and inverted V presentation on forecast soundings. And areas which see training stronger showers and storms could experience locally heavy rainfall that leads to local ponding in poor drainage areas. The front will begin to stall across the northern half of the forecast area overnight, funneling more rain showers in from west to east over the area. Downeast areas are likely to remain dry as this pattern takes shape, with coastal fog possible. The front will linger in this position through the day on Monday, with diurnal heating potentially generating another round of thunderstorm chances along this boundary. Meanwhile, the Downeast region remains mostly dry with the area of forcing remaining north of that area. The front will finally begin to shift southwards Monday night, bringing rain chances through the coast while northern areas finally begin to see some reprieve.

&& .SHORT TERM /TUESDAY THROUGH WEDNESDAY/...
-- Changed Discussion --
A slow moving front will push offshore on Tuesday as high pressure builds over the north. This will bring partial clearing across the north while southern areas, closer to the front, remain mostly cloudy with scattered showers and thunderstorms. Weak high pressure will continue to build over the area Tuesday night into Wednesday. This will bring a mostly clear night Tuesday night followed by a mostly sunny day on Wednesday. An upper trough over the Eastern Great Lakes will begin to approach late Wednesday. Lift and moisture well out ahead of this trough may bring an isolated shower or thunderstorm to some far western areas late Wednesday. Otherwise, most of the area will remain dry with a partly cloudy sky.

&& .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
-- Changed Discussion --
High pressure will move off to the Northeast Wednesday night keeping the area mostly dry. Meanwhile, the Lakes Trough will continue to approach and develop one area of low pressure over the Eastern Great Lakes while another secondary low develops over Southern New England. Latest forecast guidance is keeping the secondary low to our south on Thursday. However, some moisture moving in ahead of the Lakes Low will work with some lift out ahead of the trough to bring a chance of showers and thunderstorms across western areas. The upper trough will lift to the north on Friday, but will remain near enough to bring a chance of showers over mainly central and northern areas. A bit of moisture will continue to linger over the area Saturday. However, the upper trough will be moving away to the northeast and subsidence should bring a mainly dry day. Dry weather should last into most of Sunday before the next in a series of upper troughs begins to approach pulling in moisture and some lift which may result in some spotty showers and thunderstorms in the far west late Sunday afternoon.

-- Changed Discussion --
NEAR TERM: Northern terminals: VFR to continue over most terminals through this evening, though worsening conditions possible late this afternoon in showers and thunderstorms. Cigs will continue to fall late tonight, becoming MVFR to potentially IFR over northern terminals through the day on Monday and into Monday night with more persistent rain showers through the day. W winds 5 to 10 kts with gusts to 20 kts become light and variable overnight, shifting E on Monday around 5 kts, becoming light and variable Monday night. Downeast terminals: VFR continues today and into the night tonight, though coastal terminals could see IFR/LIFR in any fog that develops. Showers possible, particularly at BGR, with a chance for an isolated thunderstorm as well, though confidence in thunder chances is not high enough to highlight in the TAF. Mostly VFR continues on Monday as rain and thunderstorms remain north of the area. Trend towards MVFR/IFR Monday night as rain and thunderstorms push into the area. Brief LLWS possible near the coast Sunday night and Monday night between around 23z-03z. SW winds 5 to 10 kts with gusts to 20 kts become light and variable overnight, shifting S on Monday 5 to 10 kts with gusts to 20 kts, becoming light and variable Monday night. SHORT TERM: Tuesday...VFR north. MVFR south. Light N wind. Tuesday night...VFR, except in any localized patchy fog late. Light and variable wind. Wednesday...VFR. Light E wind. Wednesday night...VFR, possibly dropping to MVFR late over the south. Light and variable wind becoming SE. Thursday...Possibly MVFR over the south early. Otherwise, VFR. Light SE wind. Thursday night...MVFR north. VFR south. Light SE wind. Friday...VFR. Light E wind.

NEAR TERM: A Small Craft Advisory is in effect for the outer waters this evening through early Monday morning for seas 4 to 6 ft and gusts to around 25 kts. A brief lull may take place through the day on Monday as winds and seas decrease, before winds increase once more Monday evening. There is the potential for winds to increase to around 25 kts once more on the coastal waters, but confidence is not high enough at this time to extend the SCA. SHORT TERM: Wind and seas are expected to be below SCA through next week. Humid over the colder waters may result in some fog and mist at times, especially early in the week.
