NH1 First Alert Weather: Cooler Dry Comfortable 4th of July Weekend
NH1 Chief Meteorologist
What a way to end out the month of June! Sunny skies with highs in the mid-upper 80's this afternoon with more comfortable less humid air in place. The broad scale pattern will continue to be a ridge over the western united states with a trough over eastern Canada. After brief ridging builds in for Thursday and parts of Friday, another shortwave will dive south out of James bay pushing another front through the region on late Friday into Friday night. Ahead of this front moist southerly winds will again set up. Moisture will help to increase thunderstorm potential during the afternoon hours. A few storms could be severe as winds aloft increase. The real concern may again be localized heavy rainfall producing localized flash flooding. Pockets of heavier rainfall will be possible late of Friday into the evening hours.
The Cold front will push east of the forecast area early on Saturday morning. Fog may linger in any areas which receive significant rainfall Friday night. For Saturday, the upper level low tries to close off over southern Quebec. This will put northern New England on the southern periphery of the system with increased cloud cover and a few showers possible in the mountains during the afternoon hours with the heating of the day. Looking for a mix of clouds and sun for a majority of the day with highs ranging from the mid 70s to lower 80s. Cyclonic flow will continue on Sunday as an upper trough axis pushes east. Looking for clouds to persist in the mountains along with a chance of a few showers. Expect a mix of sun & clouds downwind of the mountains. Highs will range through the 70s and lwr 80's again.
High pressure will build in from the west Sunday night as upper low lifts out of the northeast. Expect gradual clearing overnight with lows in the 50s. Crisp clear overnight wonderful for sleeping. Another upper level ridge will be shifting eastward in time fro Monday with more stable air and warmer temps. The 4th of July will be sunny in the mid-80's. A much warmer week to kick off the first week of July. By the middle to end of next week, highs could be climbing into the 90's!
