Rich`s Weather Discussion
Tropical Storm Gordon has formed in the far Atlantic. So far, the track estimates would suggest he will not bother anyone.
For us: Isolated showers are possible on Saturday but most will not see one. Otherwise, sunny, dry, warm weather is forecast through the weekend.
Enjoy the summer as it comes to an end.A backdoor front continues to sink south from the St. Lawrence River area this evening. An initial band of isolated showers made a run at the region, but quickly dissipated as dry air remains firmly in place. Latest High Resolution guidance continues to show some shower development towards midnight in Somerset county and as we cool toward the dewpoint and the front gets closer, I can see this happening so maintained PoPs there. This update served just to introduce the latest temperature and dewpoint observations and smooth trends through the first part of tonight.
Previous Discussion... A weak backdoor front is working south thru the St. Lawrence Valley at this hour. It is expected to move into the forecast area this evening...with some showers possible especially in the Dead River and upper Kennebec River Valleys.
Otherwise it will cool to near normal lows tonight with valley fog. Some marine fog/stratus is possible ahead of the front...but I do not anticipate it to be more widespread than around Penobscot Bay.
With winds onshore across much of the forecast area Saturday...temps will be slightly cooler. To find the 80s you will likely have to head west towards the CT River. Where temps will be the warmest and convergence lingers on the stalling backdoor boundary and some showers are possible thru central and northern NH.
As high pressure settles more overhead Saturday night radiational cooling is expected to be stronger. Some upper 40s are possible along with a better chance of locally dense valley fog.
Long Range Forecast:
Overview: High pressure continues to be reinforced next week across the region. This leads to low chances for precipitation and therefore little chance for wetting rains. Temperature trends warmer through the start of next week, running a couple degrees above normal.
Details: No big changes in the extended with thoughts towards resident high pressure and little chance for precipitation. Each day will have some finer details to work around when they become near/short term, but the long term outlook bottom line is dry with warm temps.
Starting Sunday, a ridge will be just arriving overhead. This will feature broad surface high pressure, so nearly calm winds and stagnant air at surface is expected. There is some differencing in guidance as to how much low level moisture lingers. The NAM model, with its moist Boundary Layer bias, keeps three quarters of the forecast area socked in with low level moisture, resulting in a stubborn stratus deck preventing much solar insolation through the day. Other global solutions mix this out, but again, there won`t be much wind in the low levels to aid this. So, some uncertainty rides across the southern forecast area as to sky condition and thus daytime highs. At the end, tweaked temps up across central ME and kept them along the model mean for points south. Drier air should be arriving from the north through the day.
Into next week, warming trend continues as westerly flow arrives around the flattening surface high. West winds tend to deliver some of our warmer out of season temps, so feel confident in this temp forecast at this time. Can`t rule out a couple climate stations to near or tie their record highs early next week, but would need good sky conditions to maximize that chance.
By mid week, low pressure will be advancing up the East Coast. Current guidance has the resident high strong enough to deflect this moisture advection, but it will be a point to watch for at least the arrival of some moisture to increase clouds or the possibility of more than just overnight valley fog.

Regional Synopsis
SYNOPSIS...
High pressure moves into New England this weekend, with warm and dry weather continuing. This will feature daytime highs in the 70s and 80s and overnight lows in the 50s. The chance for widespread rainfall through the next week is low.
SYNOPSIS...
Our weather pattern will remain dry with above normal temperatures for the weekend and into next week. Low chance for rain comes mid to late next week, but uncertainty remains high.
NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
150 PM Update...
* Dry/tranquil tonight with lows in the middle 50s to lower 60s
* Patchy ground fog late in the typically prone locations
SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/... Key Points...
* Plenty of sunshine Sat & warm with highs in the lower-middle 80s, but cooler 70s near the coast especially later in the day
* Dry/Tranquil Sat night with lows mainly in the 50s
We continue to monitor tropical development in the eastern Atlantic and near the SE Atlantic Coast. NHC shows several areas of possible tropical development, along with Tropical Storm Gordon. With the blocking ridge overhead, this should steer any tropical activity away from our region.

Manchester, NH: Last update: 9/13 - 6:13 AM
Summer warmth during the days and cool, refreshing nights continue into the weekend. We've been in a dry stretch most of this week, but a passing shower is possible both Friday and Saturday afternoons. Much of the weekend is dry though, and we'll be staying warm through next week.
Sun and clouds today with highs reaching the upper 70s to lower 80s with a light breeze (turning to a sea breeze at the coastline in the afternoon.) 10-20% chance of a passing shower after 2pm.
Fair skies and 50s for most tonight, some valley fog possible by morning.
Daily high temperatures in the low to mid 80s and just a touch of humidity in the air over the weekend. There's a chance of an isolated pop-up shower Saturday afternoon, but otherwise a mainly dry stretch continues into next week.
