NH1 Weather Insider with Joe Joyce: September 1, 2015
NH1 Chief Meteorologist
A weak backdoor cold front has pushed through New Hampshire overnight. Along with it the passage of the front is the arrival of less humid air. Dewpoints are dropping from the Lwr 60's into the 50's today. This slight change of moisture in the air will make for a more comfortable feel to the day despite the warm air still in place. Plenty of sunshine for Tuesday with highs mostly in the mid 80's, a few spots may climb to near 87 or 88 by afternoon in SNH. The Lakes will be around 82-84. Meanwhile at the coast, highs will hold in the 70's to near 80 before a sea breeze shifts in during the afternoon from the SE. A very nice warm day indeed to kick off the month of September!
If on Tuesday we are the more comfortable side of the front, that all changes Wednesday! The front will lift back out as a warm front Wednesday with winds back over to the SW. Wednesday will come with a surge of heat and humidity with highs in the Lwr 90's and dewpoints in the 60's. This will be day to keep cool, drink lots of water, and find a little relief from the heat in any way you can. Conditions will remain warm and humid right through Thursday ahead of another cold front pushing through. This front may trigger a brief passing shower, but it will be brief and short lived.
Behind this front is the big weather maker for the big Labor day weekend! High pressure follows in behind with nice refreshing dry air for Friday. A few clouds my start the day with winds from the NE, but expect Sunshine with highs in the 70's to near 80 and dewpoints in the 50's. High pressure will sit over us right through Saturday ensuring sunshine and very stable comfortable air. Saturday will be perfect weather with sunshine, light winds and highs near 80-85 degrees. As the high slides farther south, a warmer SW wind will start to bring in warmer air for Sunday and Monday with highs nearing 90 degrees.
The weather will be flat out boring for the next week or more with a huge upper level ridge in place in the eastern half of the US. That is just fine by me! Temperatures will remain warm and above the average straight through the middle of the month. Summer will not go down without a fight!
