Wow ! If that Isn’t a perfect picture of this winter’s overall pattern here in the M/A ! Of course some systems further north but only few south of this map. I hate to say it for those waiting on Spring, but another Cold shot and winter sto…rm threat for the M/A and NE is looking good for the early to middle part of next week !
It’s not very often, the M/A would see this much cold and snow with a neutral to positive NAO and no blocking. But, a strong and favorable Pacific EPO and PNA has be the pattern driver and force this winter. This has been sending the wave after wave of Arctic air downstream into the CONUS. With this comes numerous clippers and an occassional split flow and STJ, which has phased in to produce plenty of snow from the Midwest into parts of the M/A and NE.
Snowfall totals from 3-16 & 3-17 Snow event for M/A.
