The sun was justing starting to peek out here in Peterborough, NH at this hour. A partly to mostly sunny day ahead. Unsettled weather this week with a chance of showers just about every day until Friday. Turning cooler.

Cloud heights dipped lower over the course of the early morning hours, resulting in dense fog. This is most prevalent along the ME coast and NH seacoast at this hour. There is a Dense Fog Advisory through 9am as these likely will linger through morning rush hour after the holiday weekend. The High Resolution Ensemble Forecast probabilities keep low visibility over the coastal waters through much of the mid and late morning hours. Thus while fog should lift readily this morning across the interior, areas along the immediate coast may still deal with patchy fog through mid afternoon.

Warmer today as low pressure passing north of the St. Lawrence River pulls a cold front through the region today. It`s along this front that the chance for reinvigorated showers and perhaps a thunderstorm develops late this morning and afternoon. Lots of dry air will have moved into the mid and upper levels, so development of these showers will really depend on the lifting function of the front.

Instability will need to build on the heels of receding clouds this morning, and High Resolution guidance does depict an axis of Convective Available Potential Energy tracking through the mountains and most of interior western Maine. The High Resolution Ensemble Forecast soundings have an appreciable amount of Downward Convective Available Potential Energy, and showers or storms with higher echo tops should prove to have some gusty winds with them. However, lack of coverage and moisture downplays confidence in mentioning this as a significant hazard.

Center of the trough will move overhead this evening and overnight, resulting in showers approaching from the west. Low confidence in these making an impact overnight. Another mild night will be on tap for coastal and interior locations.

Wednesday will bring the chance of additional shower development and perhaps a rumble of thunder as upper trough slowly approaches the area, with broad low pressure centered near James Bay. Temperatures run a few degrees cooler than Tuesday as low levels finally switch NW with cooler conditions.

Long range:
Overview: A mid-level trough and cutoff low pressure system will remain near Northern New England through Friday, which will result in continued chances for scattered showers at times along with near average temperatures. Drier conditions are then likely by next weekend.

Impacts: Little to no major weather related impacts are expected.

Forecast Details: Scattered showers will remain possible through Wednesday night with cool overnight temperatures into the lower to middle 40s. The cold front will move over the Gulf of Maine on Thursday but a weak surface low may develop along it. This will result in scattered showers through much of the day, especially south of the mountains. High temperatures will remain cool with lower 60s across the north and upper 60s to near 70 degrees south.

Showers will likely become more isolated in nature by Thursday night as the front and weak wave of low pressure slides north and east of the area. Low temperatures will be mostly into the 40s. High pressure will build to our west on Friday but latest guidance indicates an inverted trough may develop, which would result in cool and showery conditions once again. This portion of the forecast is of lower confidence though as heights will be rising through the day. Therefore, capped PoPs to slight chance at this time. High temperatures will be into the 60s to lower 70s. Drier and slightly warmer conditions are then likely next weekend as a ridge axis moves overhead and surface high pressure slides eastward.
