850mb temps nearly -30C on Friday!

850mb temperatures will drop to near -30 to -40 C across the SNE region.  Cape and Islands could see a nasty band of ocean enhanced snowfall as a large upper low develops a surface low to the east of Maine and drops southeastward.  The location of this surface low will determine how close the band can get to the Cape and Islands later Friday.  With the massive cold pool aloft, winds will bring a ton of moisture, question becomes how strong will the lift become, and snow growth.  Right now, it is

Lack of snow is getting to the snow lovers mind!

Subtle Adjustments can bring us from the dog pound to the Great White Hurricane! **2:00 p.m. Eastern Standard Time Southern New England Weather Update** Simply put, the snow lovers across the region are at the mercy of the giant ridge over the Davis Straits and northern Canada territories.  The -NAO regime with a large 50/50 eastern Labrador vortex is currently running the weather pattern across the Eastern US.  It is dominating the weather scene.  Dry and cold arctic conditions we fee

Pattern is ugly, but begs to differ in latest models

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

After Weekend Nor'easter threat for OES exists on Tuesday!

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

First Cape Cod Snow Threat Emerging first week of December 2020

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 rig

NORTH AMERICAN PATTERN CHANGE SIGNALS ARCTIC OUTBREAK ACROSS EASTERN 2/3rds of CONUS

Weather folks love to use the Rocky Mountains and the Continental divide as the spacer between the western CONUS and eastern CONUS.  The NOAM pattern looks to be in full reversal from this past work week to the next few weeks.  The cold situates itself at peak performance in ten to twelve days.  The EURO, EURO ENS, GFS, CMC all show a strong signal towards a large +PNA/-EPO spiking ridge over the rocky mountains and the Canadian Northwest Territories.  This incredible ridge spike will create cro

NOV 15-18th Period for Winter Weather! - SNE Weather!

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!
