NH1 Weather Insider with meteorologist Bill Gile for October 18, 2015
A frosty cold airmass will be in place Sunday morning. Sunny skies in the morning will give way to some increasing afternoon clouds with highs only able to warm into the Low-mid 40's under the significant cold air advection directed in from Canada. Lows again will drop even further into the teens up north and mid 20's south for early Monday morning creating another hard freeze across the Granite state. Whatever was left of the growing season will be gone for good. It's over after this cold snap.
High pressure with NW winds will lock in the low level cold right through Monday with sunshine and highs in the 40's. As it tracks south of us and begins to pull off the coast, warmer SW winds will develop and quickly return temps to a more typical mid October airmass. A weak front will slide through Tuesday and bring a threat of showers, especially to the north country that could mix with some snow in higher elevations. Wednesday and Thursday look to get just a bit milder, but another weak system will slide through Thursday to bring another threat of a shower or two. That looks to be followed up with a fine finish to the week and the start of next weekend.
Please hikers be smart and be prepared out there. Please don't venture to the summits unless fully equipped and prepared for winter. Please hike with a friend and let people know where you will be. Have supplies in case you get lost. This is no weekend to tempt nature as changes will be happening rapidly. My advice is to stay in the lower elevation hikes and enjoy the beauty all around us. Unfortunately, with the fragile state of the foliage as it is...I do expect a pretty significant leaf drop across the north country this weekend with the active winds. Hit the colors and enjoy the best of the season while you can!
Have a great weekend!
