NH1 Weather Insider with Joe Joyce: December 24, 2015
NH1 Chief Meteorologist
It's a damp, cloudy, foggy, drizzly start to Thursday...the day before Christmas. The rain is over, but low clouds remain along with a warm front which currently sits across the state. It is the boundary between the warm and the cool. Today is one of those days where it will be crucial to temperatures depending upon which side of the front you may lie. Maine will likely be on the cooler side of the front all day. Portions of the north country in NH will be stuck in the clouds, with cooler temps in the 40's and Lwr 50's. But on the warmer side of the warm front, it will feel like spring! The warm front will slowly drift north during the day. By the afternoon, the balmy air will flood into the region breaking records in the 50's set back as far as 1871 as highs will climb into the 60's. Clouds will be very stubborn to break, but i do expect some breaking sun through the clouds during the afternoon. The warm front may lift past Laconia, but may not get much further. Overall, pretty amazing weather for Christmas Eve. It will be the warmest Christmas Eve and Christmas we have experienced in our lifetimes. Not sure if that is a good thing, but what the heck! I am loving it while it lasts!
A cold front moves across the area Christmas Eve with partly cloudy skies and a full Cold moon illuminating the Silent Night. A wind shift to the NW will make temperatures about ten degrees cooler Christmas day, but the day will be beautiful with sunshine and temperatures still running about 20 degrees above normal! High pressure will keep the sunshine and dry conditions in place. The weekend will start be a bit cooler in the 40's to near 50 as the cooler air settles in over us. Early sun will fade to clouds Saturday as our next storm system will arrive Saturday night with another round of rain and lingering showers into Sunday. A low will cross the region triggering the showers, with a cold front sliding south Sunday with a few showers, changing to snow showers in the mountains with a more significant shot of cold to return for Monday.
From Record breaking warmth in the 60's to temperatures back to Freezing and the chance of snow? Yes. I am afraid so. We know how weather can change on a dime here in New Hampshire. Monday will be a bright day, but Canadian high pressure will sit right over us keeping high mostly in the Lwr 30's! Plenty of cold air will be in place ahead of next disturbance which will spread moisture right into the dome of cold air late Monday night into Tuesday. There is a very real chance we will be seeing our first accumulating snow of the season Tuesday. There is the potential for several inches of snow. It is impossible to know all the details this far out. We have to watch so the track, the temperature, the moisture, the timing. There is are too many balls up in the air right now as our models are still trying to figure out how this will play out. It should be a moderate snow event. There may be a mix over to rain, with freezing rain in the mountains...or there may not. It's just too early to know. We will keep you informed of the latest. It should be wintry and could have an impact for motorists across the state. This will mark a shift of a colder pattern developing in the Northeast for portions of January. So far, cold shots have been brief and passing due to the lack of blocking in the upper troposphere. The cold has not been able to pile in. There are signs of a more persistent trough in the north east for January which would make it colder with an increased chance for snow. But even with this colder pattern, will temperatures be below normal? Likely just a more typical wintry cold. We will see if a blocking pattern can stick to really get this winter going and help out the ski industry.
Have a wonderful Christmas with the family!
