High pressure crosses the region through tonight, then moves east into Sunday. Meanwhile, an area of low pressure tracks south of the Gulf of Maine. A weak boundary approaches from the west on Monday and crosses Monday night. High pressure builds in from the west into mid next week.
Near Term - Through Tonight
Update... Fog and the associated radiation inversion have dissipated for today. That leaves a mixture of the ongoing smoke layer and cirrus to reduce sunshine this afternoon. The smoke continues to befuddle ceilometers with readings ranging from less than 4K feet to 20K feet. In reality, RAOBS show no clouds less than 20K ft and the smoke layer remains mostly in a layer from 4k feet to around 8-10K feet as evidenced by PIREPS.
For tonight, expect a repeat of the fog cycle. The only mitigating factor will be increasing cirrus in the southern half of the forecast area. Lows will be slightly warmer than the last two nigheights as the air mass slowly modifies.
Previous Discussion... High pressure, surface/aloft, will remain across the region today into tonight. Areas of dense fog will occur early this morning before dissipating. Areas of mostly valley fog will then form again tonight. Otherwise, expect mostly clear skies across the region today. Mostly clear/partly cloudy skies are then expected tonight. However, will also have a smoke layer aloft across portions of the region today into tonight. High temperatures today will generally range from around 70 to the lower 70 north, to around 70 interior Downeast with mid to upper 60s along the Downeast coast. Low temperatures tonight will generally range from around 40 to the lower 40s north, though mid to upper 30s are possible mostly in the normally colder northwest valley locations. Low temperatures Downeast will generally range from the lower to mid 40s.
Short Term - Saturday Through Sunday Night
High pressure persists through the weekend as the ridge axis extends from west to east, crossing into New Brunswick. The subsidence pattern will keep skies mostly clear and the weather dry. Temperatures will remain above average each day, sitting somewhere in the low to mid 70s for highs and in the mid 40s for lows. With the stagnant pattern in place and nothing to kick this particular airmass out of the region anytime soon, the threat for patchy valley fog remains each night into early each morning, with fog lifting shortly after daybreak.
Long Term - Monday Through Thursday
The blocking pattern will keep high pressure, mostly clear skies, and warm temperatures in the area through mid week. A broad trough of low pressure will skirt by to the north Monday night into Tuesday, but guidance is in agreement that this trough will have little affect on the area, with any rain showers remaining north of the forecast area. Light and variable winds will become more northerly through the beginning of the week, advecting cooler air into the area for Monday and allowing temperatures to fall into the upper 60s across the north. This shift in pattern will be short lived, with another wind shift to a more southerly direction, advecting warm moist air back into the region through mid week.
Near Term: Winds/seas will remain below small craft advisory levels today through tonight. Areas of fog on the intra-coastal waters this morning.
Short Term: Winds and seas are expected to remain below small craft advisory levels through early next week. Wind gusts may approach 20 kts over the coastal waters on Monday as winds shift out of the northwest, but will diminish into the middle of the week.
