Bitter Cold Lifts Out On Martin Luther King Day….
Bitter Cold in place this morning with gusty NW winds. Lows have dropped into the single digits. Winds gusting from the NW 20-30 mph. Windchills ranging from -5 to -15 this morning. A stinging winds and an airmass where you do not want to be “left out in the cold” without the proper attire.
Ocean effect clouds have backed in over the Cape as expected. Scattered snow showers have been flying from Hyannis to P’town. The heaviest band of snow has stayed mostly offshore but is making a close push to Truro and Wellfleet who have the best chance for some minor accumulation upto a coating. The Outer Cape has the best chance of these flakes.
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.
High pressure will crest over us tonight with diminishing winds and better conditions for radiational cooling. Many areas will fall down to near zero overnight, below zero in NW valleys. Boston will drop down to near 5. So a very cold start is likely to Monday…but a milder finish is expected. High pressure will track SE of New England . High clouds will be increasing with stronger SW winds developing in the afternoon. Highs will warm into the Lwr-mid 30′s south with partly sunny skies.
A warm front approaches Monday night with thickening clouds. A spotty light mix of light snow will transition over to pockets of frz rain early Tuesday around dawn. The best chance of any icing will be along and north of the Pike. Cold air may get stuck across the north with borderline temps in the 30′s allowing it to remain a bit icy into the morning. SNE will warm into the 40′s as SW winds will warm the low levels and allow any precip which falls to be in the form of spotty light showers through Tuesday night. Some accumulating snow is possible in the far northern mountains by Early Wednesday.
Strong NW winds behind this departing front will filter in Wednesday. Temps will start of near freezing and fall into the 20′s during the afternoon as another shot of Arctic air moves in right from Alaska. Wednesday night will be another night with lows in the single digits. Sunshine and high Clouds Thursday with a cold dome of high pressure for Thursday with highs in the 20′s near 30.
A weak short wave approaches for Thursday night and early friday which may deposits a few snow showers before dawn. Some increasing sun and seasonal temps in the mid 30′s. Our next system approaches Friday night into Saturday and will likely come with some warmer air with temps climbing into the 40′s for next weekend.
Climate prediction center has the time of January 22nd to the 28th running way above normal for temperatures. The cold just can’t lock in as we all know with out the blocking. Looks like January will end on a mild note on avearge…in between the very brief shots of cold.
