About this blog

A few massive snowstorms have gained the respectability that every storm wants to gain.  The last few blizzards to strike the SNE region have not lived up to their predecessors.  The Blizzard of 2005 and 2015 are two storms that come to mind that blow everyone away when it comes to wind gusts and snowfall amounts in Harwich, MA.  When it comes to intensity of snowfall the Blizzard of 2005 is second to none, while the duration of the storm the blizzard of 2015 wins out.  Also wind gusts 2005 wins out over 2015 as Nantucket lost power as an 86mph wind gust hit the island, while Nantucket didn't lose power to the island in the 2015 storm where a 78mph gust ended up hitting the island.  As for snowfall amounts as I said earlier, the Blizzard of 2005 beat out the Blizzard of 2015 by two inches, 35" to 33" respectively.

Explanation of December 5th Snowstorm Potential

Right now all options are on the table.  In the next 84 hours, the solutions will vary greatly in detail and overall vigor.  The reasoning for why so many options remain open for a blizzard to sunny days remains the unknowns.  The unknowns are the strength, wavelength, positioning of the factors at play.  One is the Arctic Shortwave, this is either the kicker s/w or the phasing backside s/w that determines if the storm gets whisked out to sea or comes to the benchmark location.  IF the phase hap

OES Event potentially looking white for Thanksgiving

Arctic front comes through the region by 00z Thursday, Wednesday evening around 7 pm, OES cloud streets develop several hours later as 850mb temps drop 30-40 C, around -20C by Thursday 12z (7am EST), where the OES machine should be in full force, over the ocean south of Nova Scotia the accumulations would bring 6-12" of snow over the water, but given we are close to land and need a northerly wind, that chances are we see more than .5" of snow is around 15%, snow chance around 40%, that includes

-NAO leads to East Coast Winter Storm, potential exists in New England

12z EURO and EPS mean show potential for blocking pattern for an east coast snowstorm, with cold air present, and a coastal storm on the New England coastline, models show potential for winter weather on the 27-29th of November, this could be a long duration event, but it could be rain on the coast.  Right now specifics are not smart to forecast given its still 5 days away in time.  This is still an eternity.  However, models have flipped the pattern in the longer range to a less favorable patte

Christmas Eve Clipper? Could it be a bigger storm?

GFS and EURO, as well as the new experimental GFS, show the potential for a clipper on Christmas Eve of next week Monday.  Six days until this event, which is not a lot of time to discuss the potential.  However, models are not squishing the energy anymore and therefore not shredding the disturbance as it goes through the flow over the eastern US.  Time will tell if this event becomes more substantial, but there is potential.

From Chicago to Michigan and the Central Great Lakes Winter Storm potential

A major winter storm is pegged to strike the Central US plains and the Central to western Great Lakes region later Sunday night through Tuesday of next week.  This is all a part of a large weather system powered by a central US trough, anchored by a large upper-level low-pressure center.  Large widespread snow amounts of 10-12" is possible especially in banding from MO to IL to MI.  More widespread amounts of 3-6" is likely in the region either side of the 10-12" isolated 14".  The system should

SOme signals appearing for first widespread snowstorm of the season

Other than the news that my second novel is progressing well today, we have some weather to discuss.  Teleconnections tell us what kind of 500mb pattern we can expect to shape up in that time frame.  Normally 2-4 days, his medium to high confidence, 4-8 days is low to medium and 8+ days is usually low confidence for various reasons.  Our snowstorm potential exists because two thirds of our pattern is showing a good sign for a snowstorm to impact the New England region.  First we have to have a n

18z NAM run, brings hope to a rather dry period

Latest 18z NAM brings hope to snow weenies across SE New England for next week.  In the TUE/WED time frame an explosive disturbance is running through the northern stream flow and amplifies right on the coastline, now if trends continue to a more amped up disturbance, we could see a much higher impactful storm develop near the benchmark, stay tuned!

Short Range Guidance edging northward with Precipitation shield tomorrow for Cape and Islands

Could Cape Cod see their first accumulating snows of the season tomorrow afternoon into Monday?  I think so, latest guidance is edging towards an impact with some snow, the question is how much precipitation does fall over the area?  WV suggests that the northern confluence zone and northern stream energy causing the southward movement of the precipitation is actually moving out of Quebec, Canada at a quicker fashion, is it enough to allow the southern stream disturbance to intensify and push pr

Tuesday storm could bring snows just inland

Right now if I were to do a snow map I would focus on areas just west of the Canal and focus on a Providence, RI to Boston, MA route along I95.  Snow could accumulate quickly with a quick band of heavy snows, precip shows about .50 to .75" of a quick burst on the GFS and its members, EURO and CMC are too far southeast for anything substantial at this time.  And NAM is just getting into the frame of time.  Right now there is about a 35% chance the mid levels of the atmosphere could be cold enough

-NAO block could lead to significant cold outbreak later next week

A rather potent -NAO block is occurring in our atmosphere in the Western Hemisphere this upcoming week into the weekend.  The GFS forecasts 850mb temps to be rather mediocre for intense Ocean Effect Snows, but with northerly winds at the surface through 850mb, there is a strong chance we could see ocean enhanced snowfall later next week, around the 30th of November into the weekend.  Stay tuned!

Week of Snow has turned into a Week that blows

With the many arctic shortwaves present in the flow of the northern stream, the Arctic is opened for business but remains extremely hostile for any significant coastal storms to impact the region.  With the questions remain about phasing or not phasing streams in the split flow regime spells extreme instability in the model fields.  With this in mind, no snow midweek and the next weekend system remains in question and minimal at this time.

White Thanksgiving????

Due to the presence of an -20C 850mb temp anomalies, we can expect the presence of ocean effect snow squalls, on NNW winds across most of the mid to outer Cape Cod, NWS BOX mentions 40% chance at snow over my head in Harwich, MA, and a chance at a few inches in localized areas.  Stay tuned!  As snow squalls, tomorrow night could also add to travel hazards.
