leap day sun... (am.29.feb.12)>

We have crystal clear skies at sunrise this morning... but it's quite cool.  I have an overnight low temp of 45.3F (7.4C) which occurred around 6:00am.  If it's that chilly at my place, then I'm sure it is down around 40F (4C) in some spots.

The weak upper-level disturbance we had in the area on Monday and Tuesday has dissipated, but there is still some very cold air left behind in the upper atmosphere.  As the sun heats up the surface this morning, we just might see clouds develop over the mountains, with a risk of a shower or thundershower popping up somewhere. It looks like a great day otherwise, just keep that in mind if you plan to be wandering in the hills.

Warmer air will be making its way back -- in all levels of the atmosphere -- during the remainder of the week, as a high pressure ridge builds in.  March should arrive in style, with plenty of sun, and pleasant temperatures.  We're looking at a surge of real "springtime" air by late Saturday and Sunday, ahead of the next potentially wet weather system...
