NH1 First Alert Weather: September 23, 2017
Written by NH1 Weather on .
Morning clouds across southern and coastal New Hampshire will linger for the first half of Saturday. But any clouds will be breaking and clearing by afternoon.
Jose retreats further offshore this weekend as an upper level ridge continues to build across northern New England. Mostly sunny skies this Saturday and continued unseasonably warm temperatures develop with highs in the upper 70s and lower 80s for the first full day of fall!
Very quiet conditions expected Saturday night with perhaps some high clouds spilling into the North country. There will be some patchy inland fog.
The strong upper level ridge will dominate through the later half of the weekend with mainly sunny, dry conditions. It will be very warm for this time of year with temperatures in mid 80s in most locations. There will be an afternoon seabreeze near and along the coastline, keeping conditions a little cooler in spots and dropping readings back through the 70s. Just beautiful weekend weather!
It will continue to be unseasonably warm and humid for the beginning of the work week next week with readings mainly in the 80s nearing 90 by Monday with dew points back in the 60s. Record warmth is possible!
Low clouds may return by Tuesday as winds shift onshore. During the midweek period, temperatures will likely cool off some as a maritime high pressure system allows for an east to southeast flow to develop near the surface. We will need to watch for the possibility of maritime fog forming and overspreading portions of the coastline.
Thursday will feature the best chance for showers as a strong cold front crosses through the region. I don't expect much in the way of showers with this passage. This will occur as Maria passes by well southeast of the forecast area.
