Snowstorm Western Carolinas SW Virginia Heading East & Offshore
We have been watching the progress of a storm moving into California and how weather models have been handling it as it heads east to the Gulf States and then eventually off the North Carolina coast. Nothing much has changed regarding the storm track and the impact of the upper air pattern across the Eastern US. Unless there is a last minute surprise it appears that the strong jet stream pattern across Eastern Canada is just too powerful for this system to make a run up the East Coast.
In order for this southern storm to move up the East Coast that northern jet would have to pull up northward to allow room for the southern system to turn up the coast. While weather models have been struggling with this all week, the general pattern favors that northern jet to remain a powerhouse and not pull up very much if at all. This should keep the surface storm well to our south and east with no impact other than clouds. Snow could make it as far north as Northern Virginia or the Delmarva Peninsula but it should not make it further north than there. There is always the chance that the storm could nudge a little more to the north and bring some fringe snow to Southern Pennsylvania to Southern New Jersey but it would be fringe light precipitation and nothing much more than that.
I’m making an early conservative call on snow amounts in the interior Mid Atlantic States. Elevation will drive amounts even higher to over a foot in some places inside the dark blue. Cities like Charlotte & Greensboro in North Carolina should see accumulating snows from this with amounts decreasing fairly rapidly as you head further east. Roanoke and Lynchburg in Virginia could be sitting where some of the heaviest snowfall is likely to occur. Weather models are all more bullish with snow amounts in these areas so I am taking a conservative approach to this at this stage of the game. There is plenty of time for revisions higher if required.
