Polar Vortex & A Frigid February
Watching Icy Patches & A Coastal Storm
Cold Begins To Pull Away Today...Only To Return AgainBig blue high pressure sitting over us is providing a calmer day with less of a wind chill factor. This high will be pulling off the coast and begin to wrap in warmer SW during the afternoon. This will allow temps to continue to rise through the day...but it will be a slow warming. In fact it will take the entire day of warming just to reach 32 degrees. But this will feel a whole lot better than yesterday! High clouds will continue to increase making for filtered sunshine this afternoon
Bitter Cold Lifts Out On Martin Luther King Day....The rest of us are seeing a brilliant, blustery and very cold day with the heart of the Arctic air settling over us today. Highs will only be able to climb into the teens today. Winds will start to die down this afternoon, but wind chills will remain in the single digits...despite near 100% of the sun.
Another Short-Lived Cold Shot....Temps are starting off in the 20's this morning with a west wind, and will have a tough time going much further today. Highs will climb into the Lwr 30's by midday into the afternoon...even climb into the Mid 30's for the south coast to the Cape. Temps will hold in the 20's across NH. Sunshine this morning will give way to some increasing cloudiness as clouds from the N & W will be pushing towards the coastal plain along with an Arctic front. Temps are below zero this morning across the Canadian border. This is the airmass which will be over us for the next 24-48 hours.
Mild Air Lingers This Week...But Pattern Change May Be Ahead Today we will see temps around 10-20 degrees above normal. Highs will be climbing into the 50's south of the MA Pike...Some areas may approach 60 near RI this afternoon. Holding near 50-52 for SNH.
Kicking Off 2012 With An Eye Towards The ColdLight SW winds will bring in unseasonal warmth into the 40's to near 50 this afternoon. Some cloudiness may try to sneak back in later this afternoon ahead of an approaching cold front which is currently back through the Great Lakes. This front will push through tonight with a few showers between 8 PM and 1 AM.
Warming Back Up...Again!A cold dome of air over us this morning will be slow to loose it's grip on New England. A Busy breeze out of the SW will provide just enough motion to the air to make for a chilly day with highs in the Lwr 50's with plenty of sunshine. High clouds will be pushing through during the midday for partly sunny skies at times.
Say Uncle! Dangerous Cold to Major Winter Storm...Arctic air is on the move today. The Arctic front currently in Northern New England will push off the coast this afternoon. Ocean effect snowshowers for the Outer Cape could provide some minor accumulations...D-2". Significant cold air will settle into the region overnight with clear skies and diminishing wind. Lows drop to 0 at the coast to -20 to -25 in NW sheltered valleys. Many suburbs outside Boston drop down to -5 to -15 by dawn tomorrow
Extreme! Arctic Blast to Midweek Nor'easterThe newly fallen snow is adding to the chill this morning in the single digits and teens. 850 mb temps near -15C will help keep temps in the teens and lwr 20's today. We are tracking an arctic front currently in place ver the Great lakes and Canadian border. This will approach from the west tonight with increasing clouds and a chance of a few flurries by dawn. Once this front pushes off the coast tomorrow..the cold arctic air will begin to plunge into the region with the coldest air to be found Sunday Night-Early Tuesday.
Arctic Air On The MoveHigh pressure parked over the Ohio Valley is steering in cold dry weather from Canada. Plenty of Sunshine today with highs in the Upper 20's and Lwr 30's. An Arctic front pushes through tonight and the real cold air gets on the move. Arctic air will settle in after midnight with clear skies and calm winds. Lows will drop below zero in interior valleys while hover near 10 degrees at the coast.
