This is just ridiculous. I'm in Northern VA, and so far this winter, we've been slammed. Here's the forecast from our meteorologist (I work for the FAA)
Nags Head in May cannot come soon enough. I'm ready for sun and sand and warmth!
Calgon take me away!
The upper level wave that will be the cause of our weather later this week looks impressive over Mexico (see pic below)...and as it taps into more Gulf and Atlantic moisture, it will only get more impressive. Morning computer runs have come in. You have probably heard me say as a meteorologist you like to see the various models converge on a solution as the time gets closer but these are not. So that makes the job much more interesting. One increases the amount of precipitable water by 50% (meaning 30 inches snow), the other cuts it by 50% (down to a manageable 12 inches of snow). One tracks the system faster and more off the coast, the other slower, closer to Norfolk and then with a move towards NY. The actual outcome will depend on what I said before ref the complex upper level wind flow as the system moves out of the Gulf. That's why the models are diverging and they actually flip-flopped on their solutions over the last six hours. But I know you just want to see a forecast and not listen to the waffling....so below is my updated thoughts on amounts but I reserve the right to change. And remember, the NWS is the official place for weather advisories and warnings.
So what I think I know: Lots of moisture with this wave so we will see quite a storm--when all said and done, number 1 of the new decade so far It does not look likely to have freezing rain (a good thing) but it does look like a sleet and rain mix over areas east and south of DC in the beginning of the event before change over to all snow Saturday. That will keep the snow numbers down in those areas but again I reserve the right to update any time I want (and definitely as the track becomes clearer). The actual precipitable water amounts will be larger east and south of DC so if the track was for this area to have all snow...they would see bigger snowfall amounts then areas west and north. Additionally, this will be a very heavy "wet" snow compared to what we've been seeing lately--so be careful shoveling it. Did anyone invest in snowblowers like I recommended sometime ago??!!
current numbers:
West and Northern suburbs of DC: 15-21"
DC and areas east: 12-15"
South and Southwest of DC: 15-18"
