Marine Weather and Tide Forecast for Bath, ME

NEAR TERM /THROUGH TONIGHT/
The high pressure center continues to shift off to the east of New England through the overnight hours. This brings a light southwesterly flow to the region, which helps to keep temps warmer than last night along the coast and through southern New Hampshire. Across the remaining interior, decoupling is still likely to allow for temps to drop into the 20s to mid 30s, with the coldest readings found across the northern valleys again tonight.

Following last night's hard freeze, most of the interior zones are done for the fall frost/freeze program. For the remaining areas, interior Cumberland, Androscoggin, and Kennebec county look cool enough for another night of frost tonight. A frost advisory has been issued for these areas.

SHORT TERM /SATURDAY THROUGH SATURDAY NIGHT/
The airmass continues to moderate on Saturday with a southwesterly flow and mainly sunny skies. Temps warm into the low 60s across the north and into the mid and upper 60s along the coast. Saturday looks to be the warmest and brightest day of the weekend.

By Saturday night clouds begin to increase from a coastal storm located south of New England. These clouds will be thickest across southern New Hampshire and help to keep temps warmer through the overnight, with lows mainly in the 40s. 30s are expected to remain confined to mainly northern areas. A stray sprinkle also can't be ruled out across southern New Hampshire around daybreak as moisture spreads northward.

LONG TERM /SUNDAY THROUGH FRIDAY/
15z NBM has been incorporated into the going forecast. This and they result of the ensemble suite are in reasonable agreement with the larger mass fields but details on the system early in the week and again Wed/Thu still hold differences.

Low pressure that is currently affecting the Carolinas with rain wind and beach erosion will continue to gradually move northward up the coast the next few days. Our forecast area is still progged to be on the northern fringe of the system, so PoPs and QPF are still a bit uncertain late Sunday through early Tuesday. Highest PoPs and best chance for a period of heavy rainfall still appears to be over southern NH.

The forecast area appears to be far enough north to avoid wind issues over land, with max gusts looking like 25-35 kt at the coast.

Thereafter, showers could linger through midday or so on Tuesday. Another short wave rough diving down from Canada may affect the region sometime Wed or Thurs but timing in the models in uncertain at this time.

AVIATION /18Z FRIDAY THROUGH WEDNESDAY/
Short Term...VFR prevails at most terminals through tomorrow night. The exceptions will be at LEB and CON, where valley fog looks more likely than not again late tonight, but less likely Saturday night.

Long Term...VFR conditions should prevail at all terminals during the daytime on Sunday but some valley fog is possible Saturday night, especially at LEB, HIE, and CON. Restrictions are then possible by early next week, in particular along the coast and across southern NH, as a coastal low brings increasing chances of rain and gusty coastal winds.

MARINE
Short Term...High pressure continues to build to the east of the waters through tomorrow night. Conditions remain below SCA levels through tomorrow night, but southerly flow shifts to northeasterly tomorrow night as low pressure moves up the East Coast.

Long Term...High pressure brings fair conditions to the waters through early Sunday. Seas and winds build starting on Sunday as a coastal low moves up the the Eastern Seaboard. SCA conditions are possible by late Sunday, with gales possible across the outer waters by Monday.

TIDES/COASTAL FLOODING
There will be a long easterly fetch for a few days late this weekend and early next week. Astronomical tides will be on their way down but still high enough that some minor coastal flooding will be possible centered around Monday.
