00z GFS Ensemble Chart

Looks like models are all keyed in on the cool trough the 2nd half of next week; snow levels probably down in the 1,500-2,000′ range.  Then some disagreement whether we enter a cooler and wetter period or upper level ridging takes over after that time.  This chart shows the 00z cold GFS might be an outlier.

The actual operational run is the blue line; very cold with several bouts of snow in the hills (or lower) between the 12th and 16th.

By the way, I have no idea why sometimes the images post all gray like that…I know it’s annoying.

    In other news. The weather is freaking gorgeous today! 55 for a high again. It was nice to come home open the windows and do a little spring cleaning. Fresh breeze rolling through the house, warm. I’m ready for spring. It ain’t going to snow this winter we all know that, so lets get to the second best thing. Spring, warmth, BBQ’s, and beer in the sun!
