Spring to Winter: A Saturday Night Quickie

March 6, 2010

Not much time left…I spent the last two hours changing a bunch of weather graphic fonts.  We have a news/weather update coming in about a month, and our wise graphics friends have decided to go from EURO fonts to HELVETICA.  That means every single piece of text in our weather graphics has to be changed; good times ahead.  My eyes are now crossed, I’ll try to get them back together for the show.

Usually I don’t work a Saturday, but Drew and Stephanie are both off.

I’ve perused the latest model runs and have a few thoughts…I’ll be back in a few minutes.

Okay, the first thing that screamed at me this afternoon was the lack of anything even close to snow Sunday night through midday Monday anywhere below 2,000′.  Models are very dry for about 12 hours (midnight to midday).  Although it is a bit hard to reconcile that with the satellite imagery which looks moist to me.  Then we do get some convection Monday afternoon.  Should be some good hail/thunder and probably even snow mixed in.  One of those times where it’s 48 degrees when the shower starts and 38 when it ends.

Then it’s quiet again until the next system comes in midday Tuesday with more precipitation.

That one is very interesting since the 00z models have trended farther south with a triple point on the front, keeping any southerly wind from developing in our neck of the woods.  If it was December 29th (again), I’d say a good chance of the precipitation beginning as snow anywhere from Portland north.  Considering that system arrives in the afternoon and it’s mid-March, I think that’s unlikely, but something to watch closely.  Our RPM model appears to even have snow sticking to around 1,000′ in the late afternoon/evening.  That’s pretty darn close.

Okay, those are my only thoughts…it’ll be milder once we get past Tuesday evening.
