The on-going active weather pattern is likely to feature another strong wave of energy aloft by the middle of next week pushing into the western US from the Pacific Ocean. This second system which is currently far back over the Pacific Ocean will follow closely on the heels of the early week system. Low pressure may cross the central Plains by mid-week and could impact the Mid-Atlantic region by Wednesday night or Thursday. This second “longer-range” threat to the Mid-Atlantic region will likely have sustained cold air to work with as strong high pressure will be located to the north in southeastern Canada anchoring the air mass in place. It is, however, still somewhat uncertain as to how far north and east this late week system will come and there are many days to determine the ultimate storm track and intensity, but odds would favor primarily snow in the DC-to-Philly-to-NYC corridor. Yet a third system could follow by the beginning of the following week.
The bottom line, there is a quite a good chance of accumulating snow in the DC-to-Philly-to-NYC corridor over the next ten days or so, but the all-important details will need more time to be ironed out….stay tuned.
