Old Man Winter Has A Cold Grip On New Hampshire!

2015-01-08 17:41:26.000 – Michael Kyle, Weather Observer/IT Specialist


Overnight on Wednesday January 7th temperatures across the state of New Hampshire dropped well below zero, with the coldest temperature of 34 degrees below zero observed here on the summit of Mount Washington. The temperature on the summit dropped low enough that we were able to perform some fun cold weather experiments; turning boiling water to snow and blowing bubbles that freeze in mid-air.

These sub-zero temperatures were the result of a deep upper level trough that transported artic air down into much of the eastern half of the United States. This deep tough will continue to keep temperatures across New Hampshire well below average into the weekend. By Sunday, temperatures will rebound slightly as the upper level trough lifts north of New England. Despite this, temperatures will still remain slightly below average for most of the state behind the exiting trough. By the start of next week, areas across southern New Hampshire could see temperatures breach the freezing mark. This will be short lived however, as another upper level trough starts to swing south from the Hudson Bay region, sending temperatures back to well below average yet again.

In the picture above you can see the top shows the next upper level trough starting to deepen to the west and then by 1/13 (the bottom) the trough will move through the Northeast, sending temperatures back to well below average. Although Old Man Winter’s cold grip will be holding firmly onto New Hampshire that doesn’t mean you can’t get and and enjoy it. Its just requires a few more layers.
