SYNOPSIS
High pressure will continue to build over the region today. As winds turn to the southwest on Saturday a warming trend can be expected over the weekend into early next week. A weak front will bring a few showers Saturday night into Sunday. Monday will be warm away from the coast, with cooler temperatures along the coast where an onshore flow of cooler air will develop. Expect a better chance of showers on Tuesday along with cooler temperatures.

NEAR TERM /UNTIL 7 PM THIS EVENING/
After a frosty start, temperatures will rebound through the 50s today, reaching the lower 60s over southern New Hampshire. There will be a sea breeze in the afternoon along and near the coast as the gradient will be very weak. The day will be mainly cloud free as a large area of high pressure builds over the Northeast from Canada. Have continued to trend towards lower surface dew points with readings in the 15 to 20 range with good mixing through the day.

SHORT TERM /7 PM THIS EVENING THROUGH 6 PM SATURDAY/
Forecasting another rather large diurnal range tonight. Clear skies, light winds and continued low surface dew points will allow for radiational cooling once again. Temperatures will dip into the 20s in most areas with some lower 30s along the immediate coastline and portions of southern New Hampshire.

The large area of high pressure will begin to ease off the Northeastern Seaboard on Saturday. This will allow for warmer temperatures climbing well into the 60s over interior areas as winds begin to shift out of the south. Along the coast, it will continue to be cooler, in the 50s due to onshore winds.

Warm temperatures over the interior along with nearly full sunshine may necessitate the need for an Inland Cold Water SPS.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/
Overview: While there are currently no major weather systems on the horizon, a few weak disturbances will bring the potential for scattered showers at times. Temperatures will generally remain near average most days, although Monday stands the best chance for being above average.

Impacts: Little to no major weather related impacts expected.

Forecast Details: An h5 ridge axis and surface high pressure will remain over the region through Saturday with increasing WAA aloft ahead of a weak warm front that will cross on Saturday night into Sunday morning. This front will bring the potential for scattered rain showers, especially across west-central NH and extending into northwestern ME. The added cloud cover and moisture will allow for a relatively mild night with many spots only falling to within a few degrees either side of 40.
Increasing WAA aloft combined with onshore flow will keep relative humidity values higher than previous days on Sunday and there will be quite a bit of at least high-level clouds as we remain near the top of the h5 ridge axis. A few weak pieces of energy will traverse over the region through the day, which may result in scattered rain showers... mainly over the north.
Highs will be primarily into the 60s, although a few spots in southern NH could reach the 70 degree mark. Once again the ME coast will remain cooler due to the onshore flow.

Scattered showers will end Sunday night with some clearing skies south of the mountains. Lows will range from the 40s to lower 50s.
The ridge axis will remain over New England on Monday as we sit in the warm sector, resulting in partly sunny skies and warm highs into the upper 60s to perhaps middle 70s south of the mountains. The warmest readings will be across interior southern NH and extending perhaps into the western ME foothills. The coast will likely top out into the 50s to near 60 before onshore flow develops later in the day. Other than a stray shower, Monday night looks to remain mainly dry with lows into the 40s and 50s. The ridge axis will then begin to break down and move east of the region on Tuesday as low pressure near Hudson Bay sends a series of fronts eastward towards New England.

Latest guidance is trending cooler for Tuesday as winds become more easterly behind a potential backdoor cold front. Thus, now expecting most locations to top out into the 50s, although a few locations in southwestern NH could still reach the low 60s.
Scattered showers are also likely, especially during the afternoon and night as a cold front and potential weak sfc low moves through. Shortwave h5 ridge axis and sfc high pressure then builds for Wednesday with mild temperatures and mostly dry conditions before shower chances increase towards late week as the next frontal system approaches from the west.

AVIATION /07Z FRIDAY THROUGH TUESDAY/
Short Term...VFR conditions expected today through Saturday.
Afternoon sea breezes expected along and near the coastline during the afternoon hours.

Long Term...VFR conditions prevail through the period outside of any widely scattered -SHRA. The greatest potential for MVFR restrictions will be Saturday night into early Sunday and then again on Tuesday. Winds will be primarily out of the south but should remain largely below 20 kts.

MARINE
Short Term...Variable winds expected in the near and short term portion of the forecast. Winds will be locally onshore during the afternoon hours today and Saturday.

Long Term...Winds and seas remain below thresholds hazardous to small crafts through the period.

GYX WATCHES/WARNINGS/ADVISORIES
ME...None.
NH...None.
MARINE...None.
