Recreational Forecast

Mountain Forecast:
A few clouds will linger over higher terrain especially in the White Mountains this morning. Then in the late morning into the early afternoon clouds will give way to more sun with a combination of sunshine and high clouds. Clouds are expected to linger over the White Mountains through the afternoon. Highs today will get into the 30s with a few of the highest summits staying below freezing. Good news is the wind will remain on the lighter side, therefore temperatures will feel like the 30s. Overnight tonight a chance for snow showers develops in the early morning hours mainly for the southern Greens, and the Whites. Then snow showers will turn over into rain as the temperatures warm up. Showers will become more widespread as the day goes on. Then rain could change over into snow overnight as temperatures dip. Precipitation is expected to continue through the end of the week.

Wind At Lower Elevations:
The outlook for today, is light and variable wind, then Thursday calls for winds becoming east to northeast 10 to 15 mph, some gusts to 25 mph over the higher terrain.

Detailed Discussion

The high pressure system that brought us dry weather yesterday has moved off the coast of Maine. It will continue to move out over the coast. There are a few clouds this morning blocking the stars. Clouds will stick around a bit longer over northeastern Vermont, and even as clouds begin to burn off later in the day (due to that high pressure moving off) we will likely still have a few high level clouds stick around and some areas could see more clouds than others. Today we will see more seasonable temperatures with highs expected to be from the upper 40s to near 50 with a few low 50s possible more locally in northeastern Vermont. Calm wind is expected today and if we do get some sunshine it might feel a bit warmer than the upper 40s to low 50s.

Although we will likely see some sunshine today this wont last long as, clouds will move in overnight tonight. We have a low pressure system to thank for these clouds. Although the low won’t bring precipitation into northeastern Vermont until sometime on Thursday it will produce some clouds ahead of it later tonight.

Overnight tonight and early tomorrow morning for Thursday, a low-pressure system currently positioned over southern Quebec, along with a secondary low-pressure system situated over the Great Lakes region, will begin the merging process. As these two systems interact and intensify, they will bring round after round of precipitation across the northeast. Although it will remain dry today as these systems stall out we will likely see precipitation by Thursday morning and it will likely stick around through the end of the week and even into Saturday until the combined low finally makes its way eastward.

Overall we are looking at some rainy weather continuing day after day this week for a much needed break in this dry spell that has been contributing to drought conditions. But today we will have one more dry day with some sunshine poking through this afternoon here and there before the rainy weather makes its way eastward by Thursday.

Though much of Vermont and New Hampshire were still wilderness in the late 1700’s, early pioneers regarded the snow storm that occurred on this date in 1798 as one of the worst. 30 inches were measured in Hanover, NH at Dartmouth College. It was the beginning of a long winter, as evidenced at Keene, NH, where on May 11th of the following spring, 2-3 feet of snow was still in the woods!
