NH1 Weather Insider with Joe Joyce: September 23, 2015
NH1 Chief Meteorologist
Bye Bye Summer! It was really really great this year and I am going to miss you badly. Those who complained about your heat have NO IDEA what real heat and humidity really are. Did we break the mid 90's once? Maybe once. Big thumbs up to this summer with thankfully no hurricanes and really very little damaging severe weather to speak of, with the exception of the tragic Lancaster microburst and tent collapse. So we move on to Fall this Wednesday and many are welcoming the change of the seasons. The Equinox is upon us where the sun is shining directly over the Equator. We have equal length of day and night. The sun rises due east and sets due west. What a day outside to welcome Autumn! Sunny skies, light winds low humidity, and warmer temps! Highs will be in the mid-upper 70's this afternoon, with a sea breeze kicking in to cool the coast later. A weak front pushes through Wednesday night, with building high pressure from Canada following in behind. This high will provide another round of cooler, dry air from Canada. Clockwise rotation of air around this high will wrap in a steady, cool onshore flow in off the water for Thursday-Sunday. This steady wind over the water will create a fetch and allow the surf to increase off the coastline this weekend into the start of next week. Temperatures will remain in the 60's near 70 from Thursday to Sunday with sunny to partly sunny skies with this high sitting near or right over us.
While a Canadian high sits right over us protecting our weekend, a developing low near the Carolinas will be trying to push north. The High will not budge, so a strengthening gradient between the high and low will bring some gusty winds from the ENE for many coastal locations from the Carolinas to the mid-Atlantic all the way to southern new England. Building seas will become a problem during the high astronomical tide south of New England, along with gusty winds and some rain.
High pressure will ensure sunshine this weekend across New Hampshire. With onshore winds, you always have to be aware of tricky low clouds backing in. It is always possible and will remain so...especially this far out. It will be a great first weekend of fall across New Hampshire. Very comfortable air. A big night in the sky for the Super Blood Harvest Moon with a Total Lunar Eclipse Sunday night! What a mouth full! There is plenty going on with this moon that makes it special. It is making it's closest approach to the Earth this month. Meanwhile a total Lunar Eclipse will be happening at that moment as well! What are the chances? Not good actually. The next time this will happen will be 2033! What will the world be like then? Hard to fathom. See the graphics below for more information on this celestial event we will be talking more about as we get closer!
