    After the story of Kawhi Leonard now wanting out of San Antonio Spurs could change the landscape of the NBA this season.  He could go to Lakers and create a superteam with them bringing in Lebron James and Paul George.  However, the Boston Celtics will be in the mix for the top 2 player and NBA finals MVP and they could offer the Spurs a much better package of young talent and picks.  He could bring the Celtics a title next year with Kyrie Irving, Gordon Hayward, Jayson Tatum, Kawhi Leonard and Al Horford in the lineup.  Will Danny Ainge be willing to part ways with a few bench players, including potential NBA star in Jaylen Brown; as a Jaylen Brown fan personally, I would trade Jaylen Brown and do a sign and trade with Smart for Kawhi Leonard including the best future pick the Celtics have in their arsenal, the Sacramento Kings pick in 2019.  Thoughts in the comments section?

    50 degree temperatures for the first time on the Cape this winter season, were in the calendar/met Spring season which started on March 1st, but official spring begins on March 20th.  Today, Tuesday, March 9th, 2021 is the first time I recall Chatham, MA reaching 50F+ temperatures, and there was no nipping wind.  The winds are light out of the southwest, I do not feel fog will be an issue tonight as temps drop off as is during the Spring months.  Again, winter could spread its wings for a short unsustainable day or two, but nothing suggesting a three plus day period.  Honestly, I believe winter weather is gone for SNE this year until November, and our hurricane season could be quite active and violent.

    I have drawn a graphic illustrating the next few weeks of the weather pattern across North America.  The northern hemisphere will favor a regime towards an evolving combination pattern of a -NAO/-AO/+PNA.  The red in the picture represents the presence of ridging in the mid-upper levels and the blue represents the troughing areas of low pressure in the mid to upper levels.  The ridging over western CONUS and eastern PAC ocean along with ridging across AK, to northwestern Canada northeastward to Greenland supports a -NAO blocking pattern regime to expand and stay put through the end of the month.  How long this lasts no one knows for sure, but its presence while does not guarantee snow, it will bring a stormy and much colder air pattern across the eastern CONUS.

    The image I will share is the storm and the dynamics associated with the storm potential for tomorrow and the evolution that could help determine a blizzard or a near miss for the Cape and Islands.  AS the pressure drops in the low, the intensity and the pressure drop will help determine where the heaviest snows occur northwest of the low's track at the height of the pressure drops.  If the storm blows up and deepens 15mb/6-12 hour period, just northwest of that low track will determine the heaviest snowfall rates.  Convection will explode, cloud tops will cool rapidly as they expand upwards vertically.  Tomorrow's nor'easter and potential impacts will be determined when the low blows up and starts the rapid bombogenesis phase.

    Huge potential and yet very far away from happening.  We have a pattern characterized by a building +PNA, a budding -AO and a substantial -NAO block like pattern.  One issue in the pattern is the strongest PV like low is over the Canadian Maritimes near Nova Scotia and New Foundland, Canada.  This entity is causing a massive southern dislodge of a streak called confluence.  Confluence is the property of the atmosphere where the jets are coming together, like convergence.  This supports a strong area of surface high pressure, since convergence at mid to upper levels promotes sinking air to the surface, while divergence promote lift i.e. precipitation and moisture.  What we have hear are three systems influencing one another and mucking the other's potential.  We have an arctic jet vorticity maximum rounding the western circulation of the PV (50/50 low) into Northern and Central New England by 3 1/2 days out.  Models also have multiple southern stream disturbances over the Central Plains.  Now with several energetic systems in play, there is the question of timing and phasing.  Again, we will not know until within 18-24 hours from onset of precipitation.  Again, a lot to process.

    Reminder...

    By USCAPEWEATHERAF,

    My novel, being self-published on paper back and eBook forms on Amazon will become available for purchase on January 1st, 2021.  My name is James W Nichols, with the title of "The Awakening Dawn: The End has just begun!"  It would be nice to get a fanbase going and build it upwards.  It is hurricane disaster based!

    Potential exists for Ocean Effect Snow bands to develop as an upper level low develops to the southwest of the region.  Now the evolution of said trough and upper level low remain in question as overall the guidance for 12z 12/06/2020 is still questioning this transition.  Newly updated water vapor imagery as I watch, shows the main energy that develops into the upper level closed low is still diving southward with no eastward motion.  This suggests it will try and phase with the southern stream system and create a formidable surface storm over the North and South Carolina piedmont region.  This low has two avenues of track, one to the ENE and off the coast with little fanfare, or two up the East Coast in more of a NNE track.  The latter performs a major impact event for eastern New England, while the former represents little impacts.  Ocean Effect Snows will only develop if the ocean storm tracks close enough to the region to veer the flow from an anticyclonic burst of westerly winds, to a more cyclonic burst of NNE to N winds across a very mild Gulf of Maine and Cape Cod Bay.  850mb temps which are found 2500 to 5000 feet above the surface of the ocean, dive into the -6 to -12C range for a good 36 hour period.  The winds veer to north-northeasterly at the same time and provide the necessary forcing for ocean effect cloud seeding and developing of snow showers.  Again any accumulations will be light!

    Models are beginning to show an area of focused vorticity rounding the base of neutral to negatively tilted northern branch of the jet stream trough.  Now, energy is over the central North Pacific south of the Aleutian Islands which means the energy is not being sampled properly at this time.  However, multi model consensus is beginning to show prudent signs that this trough will be energizing as it moves through which far more productive than a trough that is weakening instead.  We have the right trends going as the system ignites over the extremely warm waters relative to average norms for November 30th.  While the warm waters are a concern at times, this system will not be driving southeast winds, so the area should remain in a cold environment, enough for snow, I have no idea.  Right now, the threat has begun to emerge for Friday December 5th!

    I just want SNE folks to realize and soak up the warmth the next few days, until a second GRT Lakes storm moves through day 3-5 and then brings a powerful cold front through the region.  This should usher in very cold, arctic like air mass into the region and the upper level pattern looks to lock into a +PNA at least through the first few days of Thanksgiving Week!  Stay tuned, a coastal redeveloping clipper could move through the region as well around the 17th/18th.  Stay alert!

    As Celtics Nation and the sports world knows, the one player that everyone associates with the Celtics organization for over sixty years has been the one and only Tommy Heinsohn, one of four players ever to be in the hall of fame in Springfield, MA as a player and a coach and as a broadcaster.  Tommy earned eight NBA championships with the Celtics in his nine year NBA career and two more as a Celtics head coach in the 1970s and had spend the final 39 years of his wonderful life as a NBA broadcaster for the 17 time NBA Championship Franchise Boston Celtics.  Mike Gorman his play by play man side by side for the last 39 years, brought up a tremendous idea that the Celtics players should have his Celtics jersey number 15 retired to be pinned on the players' jerseys during the games this season, then Brian Scalabrine went a step further and said the NBA as whole might want to show continuity as a whole behind the legend of the NBA with his impact beyond the Celtics.  Tommy will forever be missed, but we know God has welcomed him to eternal life!  November 10th, 2020 a day we will never forget a year which we hope will leave in the rear view mirror for reasons behind simplistic beliefs.

    Again, the fall season still wants to remain warm across the eastern CONUS.  Right now, the pattern to Wednesday resembles a troughy but zonal pattern aloft where westerlies remain in control with several troughs moving through the region before the region warms significantly as pattern amplifies into a ridging in the East and troughing in the west pattern.  This is supported by the teleconnections across North America of a strong +NAO/-PNA/+AO pattern.  The only semblance towards a more average pattern temperature wise is with the AO heading neutral by day 15.  Right now, there are no true signs that point to a renewed cold regime in the next two weeks.  Soak up the warmth for the next few weeks.  Sun will continue to set earlier each day until the first day of calendar winter season.

    One thing is for certain during an active La Nina winter season, the ENSO while in the mid cold phase between -1 and -2C below normal, the northern branch of the jet stream will be very active from now until the La Nina relaxes towards the beginning of Spring 2021.  This winter should provide a rather volatile change in the three day periods.  We will go through changes of warm and cold air masses and active storm tracks either north or south of the region.  Cape Cod has always been the benchmark for rain versus snow.  For events coming out of the northwest, like Ontario, Canada, we would prefer the low track south of Block Island, RI, while if the storm track is from the southwest, we prefer the track to the south of Nantucket.  If the clipper season is active, we should see a few 8-12 inch events from ESSEX to NANTUCKET.  The next seven days provide a nice interior event and two potential last minute developers off Cape Cod.  Let's see how this Friday system works out.
