Synopsis for stonington me to merrimack river ma out to 25 nm.. Steady offshore is expected for the foreseeable future with fronts occasionally crossing the waters and enhancing winds and seas. A front crossing tomorrow morning will bring renewed gusty winds out of the northwest, possibly hitting gale force over the southern portion of the coastal waters late Thursday and again late Friday. Lighter winds are expected for most of the weekend and early next week.

SYNOPSIS. Low pressure aloft will keep northwesterly flow and mountain clouds and showers in the region through Friday morning with increasing winds on Thursday. Temperatures will begin to warm slightly through the weekend and warm up significantly at the start of next week as high pressure builds into the region.

NEAR TERM /THROUGH TONIGHT/. This afternoon, satellite and upper air analysis shows broad upper level troughing over northeast NOAM centered over the Canadian Maritimes with weak riding upstream over the Plains and Mississippi River Valley. Between these features, we get a steady westerly to northwesterly breeze. A diffuse wave rounding the base of this trough continues to produce widespread cu and stratocu for the region with snow showers over the mountains. These are not and will not amount to much into tonight outside of a couple/few inches for the peaks and an inch at best for the valleys. Seasonable temperatures this afternoon gradually dip into the single digits (north) to the low/mid-20s (southern coast, southern interior). Not expecting a great radiational cooling night by any means thanks to the PGF and some lingering cloud cover behind the crossing cold front.

SHORT TERM /THURSDAY THROUGH THURSDAY NIGHT/. The first of two cold fronts crosses the region during the morning as the trough aloft amplifies over New England, allowing the column to dry, lapse rates to steepen, and the PGF to tighten further over the region. Thus expect winds to pick up and skies to clear for Thursday with west-northwest winds gusting to 30-35 mph. Took the high end of guidance for temperatures downwind of the mountains with temperatures rising into the 30s to near 40 for the southern zones and limited to the teens and 20s over the north. Later in the day another front approaches from the north with an increase in clouds and return of snow showers over the upslope areas of the Whites and mountains near the international border. This will reinforce steep lapse rates and continue gusty northwest winds into Thursday night.

LONG TERM /FRIDAY THROUGH WEDNESDAY/. Overview: Looking at the week ahead we see a persistent long wave trough over the northeast US. That will lead to a pool of colder air aloft with northwesterly flow through the region. A ridge build downstream over Iceland with a positive NAO persisting into next week will keep that pattern from progressing much for the next 4-5 days.

Moving into the start of next week the hemispheric pattern opens up again allowing for the potential for a series of waves to move through. With that progressive pattern is a trend towards warmer temperatures as highs return to the mid to upper 40s across the south.

Details: Friday will see cyclonic flow over the region. This will bring upslope snow showers and clouds into the mountains. With Froude number indicating a chance for the showers to make it over the mountains have kept the Pops slightly higher. Still any accumulations would be very limited. Winds will remain brisk, around 10-15mph from the NW. Forecast soundings show the core of a 50kts low level jet remaining above the inversion, so have kept gusts capped around 20-25kts for all but the highest elevations, although a few gusts up 30kts possible through the afternoon.

Saturday and Sunday will be similar with the upper low gradually pulling out to the northeast allowing for winds to decrease and temperatures to rise slightly. Southern areas will see temps pop back above freezing by Sunday, thanks to mostly sunny skies. A few upslope clouds may linger in the mountains but the dry NWly flow won't have enough moisture to support showers through the weekend.

To start next week high pressure builds in and starts a warming trend. Temperatures will rise to the 50s across southern New Hampshire. With flow out of the SW favorable for the warm air advection have pushed temps a bit above the NBM and towards the MEX especially for southern NH and SW ME.

AVIATION /20Z WEDNESDAY THROUGH MONDAY/. Short Term . VFR prevails with westerly northwesterly winds turning gusty to 25-30 kts tomorrow. MVFR persists at HIE and is possible at times for LEB through the evening, eventually lifting as clouds dissipate late tonight. MVFR cigs/SHSN may return to these sites, particularly HIE, later tomorrow as another front drops through.

Long Term . Northwesterly upslope flow will linger in the mountains through friday morning with MVFR conditions likely.

MARINE. Short Term . Offshore wind gusts of 25-30 kts over the western outer waters gradually grow in coverage as the PGF tightens over the region tomorrow. There is a chance that the southern coastal waters may see Gale force winds tomorrow afternoon into the overnight as a pair of cold fronts drop through the region, for which a Gale Watch has been issued. Otherwise seas remain fairly benign in this regime, approaching 5 ft along the outer periphery of our zones during the Gale Watch period.

Long Term . Northwesterly flow with a few gusts to near gale are possible through the end of the week as low pressure remains over the Maritimes. Winds and seas will subside for the weekend and into next week as high pressure builds in.

GYX WATCHES/WARNINGS/ADVISORIES. ME . None. NH . None. MARINE . Small Craft Advisory from 4 AM to 3 PM EST Thursday for ANZ152- 154. Small Craft Advisory from 7 AM to 3 PM EST Thursday for ANZ151. Small Craft Advisory until 3 PM EST Thursday for ANZ150. Gale Watch from Thursday afternoon through Friday morning for ANZ154.
