NH1 First Alert Weather: Damp Friday, Mostly Dry Weekend
NH1 Chief Meteorologist
A cloudy damp day can be expected this Friday. A moist southeast flow will keep us cloudy as the weak surface low and trough to our south move northeast. Precipitation will once again be light with mostly pockets of drizzle and light rain showers across the forecast area and snow showers in the mountains. Accumulations across the northern mountains will range from 1-3". Temperatures will warm into the 40s south and mid 30s in the mountains.
An upper level trough will set up over the region on Saturday. Models have been shifting the axis of this trough farther to the northeast which is good news for us. Surface low pressure now appears to be a little later developing and much farther south and east than previous runs. Saturday will still be mostly cloudy, but most of the time will be dry. There could even be breaks of sun, with highs in the mid 40's...seasonal for this time of year. Colder temps aloft would suggest at least an some scattered snow showers will be possible with low level moisture and upsloping NW winds.
The upper level trough of low pressure will remain in place across northeast zones Saturday night into Sunday. This will keep lots of clouds around with scattered snow showers persisting on and off across the mountain. Highs Sunday will range through 30s north and lower 40s south. Low pressure will continue to meander over the maritimes on Monday as high pressure builds in from the west. Expect diminishing clouds and skies becoming mostly sunny. Highs will range through 30s north and lower to mid 40s south.
Fair weather will continue Monday night and Tuesday as high pressure crests over the region. Will see increasing clouds Tuesday as a broad area over-running shifts in from the west. Looking for moderating temps with highs from the mid 30s to lower 40s north and mid 40s to near 50 south. Rain should arrive by lat Tuesday or Tuesday night. The Midweek still looking unsettled as over-running ahead of low pressure sets up over the northeast with increasing threat of rain, heavy at times. Low will track west of New England coming with moisture from the Gulf of Mexico so there will be the potential for heavier rain and downpours. Rain could last into Thursday with another low tacking up the coast. There are uncertainties with the timing of the rain next week...but the rain will come in waves and be heavy at times. This should help much of New England with the current drought. Winter lovers are going to have to have a little patience as we are moving into a mild and wet pattern through early December.
