FCST Christmas Week 2009

First to start out there are going to be 2 systems moving in, one tonight through tomorrow morning and Wednesday through Christmas day depending on frontal speeds this system could linger until Saturday AM but it's a ways off so a little too early to tell right now.

System#1
This one is looking like it's going to dump a max of 3" on the area, NW is going to be hit the hardest with the max of 3" and we are looking for 1" tops in RV. Overall a rather fast moving system but it's got to get out of the way for the new system coming in on Wednesday. Here is the lifted moisture that is possible precip.



System#2
I'm planning on elaborating more on this either tomorrow afternoon or Wed. AM, it depends how my schedule works out. For the most part over the plains we are looking for heavy precip, 8-12" possible with strong winds to bring it to a blizzard condition.

Down south there is a slight chance of SVR WX Eastern TX, Western AK & LA. here is a graphic to show dew points & mixing winds. This doesn't have a huge CAPE rating but it looks as though this should be enough to have some super cellular storms along with a couple smaller tornado's that could be reported.
