Clayton Stiver's 7-day NH1 Forecast for Wednesday, Dec. 17, 2014

Source: NH1 Chief Meteorologist -

Freezing Rain Advisory in effect from the National Weather Service for Grafton, Northern Carroll, and Coos Counties until 8am Wednesday. Around 0.05" total ice accumulation possible mainly for higher elevations.

A weak wave of low pressure and frontal boundaries will track across the Granite State over the next 24 hours. These systems will be positioned across the Gulf of Maine by Wednesday Evening. Mostly rain will fall with anywhere from 0.25" to perhaps as high as 0.75" Higher elevations from the Upper Valley through the Mountains and Great North Woods may see a little ice accumulation.

High pressure will settle back in for the end of the week into the start of the weekend bringing fair skies. A north to northwest flow of wind and a dip in the Jetstream will bring a return to normal or just below normal temps. Those northerly winds could be gusty.

We continue to monitor the forecast for Sunday as computer models are showing a possible coastal storm that could bring wintry weather to the area. It's still too early to make any calls on snow and/or ice amounts, but if you have travel plans, you'll certainly want to pay close attention to the forecast. The latest data suggests this storm system will be relatively disorganized and track far enough south and east of NH that only light amounts of precipitation would be seen. This is still very much subject to change however so stay tuned! A stronger storm system may impact the area by Christmas Eve or Christmas Day of next week.
