NH1 Weather Insider with Joe Joyce: April 9, 2015
NH1 Chief Meteorologist
Well that was fun! A burst of snow pushing through last night gave a few inches of snow across New Hampshire.
Those of us living in the Lakes region and hills are waking up to a wintry scene Thursday morning. The concern is the low level persistent cold which has been in place through the overnight. Even though the main batch of snow is over, a slippery icy start to the morning in spots. The culprit is warm air which is over riding the cold low level cold air in place. The air is saturated. Low clouds are locked in with 100 % relative humidity and freezing drizzle and sleet could be an issure during the early morning hours with temps near freezing at the ground.
Any moisture in the air could freeze on colder surfaces so there is a potential for a light glaze on the cars and side walks Thursday morning.
Temperatures will warm up slightly Thursday but not by much. In fact, keep the coat handy because it will be a cold raw day for April standards. Cool east winds and clouds will help to keep temps in the 30's all day, along with the damp conditions. Our next batch of rain arrives Thursday Night. This will be energy from weakening severe storms from the midwest, but it will also signify the leading edge of milder air which will eventually arrive in New Hampshire.
The concern is as this rain arrives, high pressure to our NE will still be supplying the cold low level air. There is a definite cold air damming signature for the moutains and valleys Thursday night for the potential for Freezing rain. The rest of us will just get wet Thursday night with temperatures slowly beginning to rise.
Showers will taper off erly Friday morning as a warm front lifts through New Hampshire. SW winds will direct temps into the mid 50's under mostly cloudy skies. If we get a few breaks of sun, look out! Temps will climb to near 60, but that will also give us a better chance of a late daty thunderstorm! A cold front will push through by the end of the day with late day showers, but any added heat or energy could destabilize the front and turn showers into a few Thunderstorms!
Breezy west winds will dry us out for the weekend behind the front. Cooler air over our heads will allow for fair weather clouds to form during the afternoon. Sunday will likely be the sunny and the warmer day of the weekend with temperatures approaching 60. Very mild 60's heading into next week. Winter is out of time!
