Lowland snow for tomorrow morning?

Good morning to all.

It appears once again, that winter may come to visit us for tomorrow morning as there is the possibility of a little snow(attached images 11am-30hr and 5pm-36hr).

So here`s what the UW models show. Last nights 00zNAM had an area of weak low pressure swinging just north of the central sound which would mean no chance of snow except for maybe the North interior. However, the 00zWRF swung the low across the central sound with marginal cool temps for a little snow. But they were JUST MARGINAL with 1000ft temps reading 33/34 degrees with 850mb temps also being just cool enough for maybe a rain/snow mix.

But on this mornings models, the 12zNAM is still a tad a warm, but also brings the weak low through the central sound for early
tomorrow, while the 12zWRF has the low just slightly south of the of the central sound and still brings the possibility of a little snow, with again, temps just above the surface(1000ft) being in the 33/34 degree range. Now as far as the operational NCEP 06z/12zNAM and 6z/12zGFS models, they are more inline with bringing the even weaker low just south of us. So will some of us see a little snow? It`s possible, but I would`nt get your hopes up as this looks to be VERY MARGINAL at best with maybe a dusting to an inch on the higher hills across the lowlands. So we`ll see what happens.

  1. I can't wait to see the next update on the 24 hour snow map. If everything happens right, how much snow could we get out of this tomorrow? What about tomorrow night and sunday?
    Thanks.

  2. I must say, Brett, you are the more likely person to post on here that I have seen so far. Just would be nice if more people would post here on my blog and also getting more comments/questions similar to Cliffs blog.

    Regarding your question. If you read my entry, I said that maybe a dusting to perhaps an inch or so could fall as this will be a marginal...make that very marginal...snow threat coming in. And as far temps go just above the surface, they to will be very marginal. So maybe a stray shower Sat night, but that will probably be it.
