What?
So far, what I said yesterday still holds weight, but the last 24 hours have given some clues to how minor the event may be for us. For one, the models had missed a strengthening of the Pacific jet in the Pacific NW/ Western Canada. So what? Well, this will weaken the ridging in the western United States and that has a ripple effect. Namely, the strength of the eastern trough, or ability for a storm to really drop far south, correlates with the strength of a western United States ridge. This western US ridge is known as positive Pacific North American (+PNA) weather pattern ItsÂ’ development has been a major culprit in bringing the first cold to the Eastern US.
So yesterdayÂ’s alert:
Â… A low will come out of Canada this weekend and go through reformation off the VA Coastline. It is a little unclear what happens exactly here, but experience says this system will only bring some light snow to the region and minor accumulations (mountains more, and Northern/Northeastern Maryland needs to pay a little more attention), if anything at allÂ…
Comments:
Right now, flurries seem a more likely bet than accumulations. My caution to Northeastern Maryland is that a wrap around on the backside of the low may give a bit more snow, but wrap around bands are really hard to forecast!
When?
This event will commence Sunday evening and overnight.
Impact?
I continue to see a small accumulation possible in some areas. As I noted yesterday, the first flakes will be seen by many in the northern third of the region east of the mountains.
Many things can change between now and the actual event. I will update when possible
Summary:
Pretty much unchanged:
Snow flurries/showers will likely be seen in areas this Sunday that have not yet seen it this year, but, so far, the impact will likely be minor, but the storm has a lot of potential.
FYI.. Next weekÂ’s more favorable weather pattern may not be as strong based on the changes seen in the models the last 24 hours.
BUT.. I am still "Dreamin'"!
More to come!
