close to the norm... (am.25.oct.13)>

Our skies are 100% clear just before sunrise this morning, though there is a bit of light haze in the air.  The temperature here in the upper part of town is 56.4F (13.6C), with a humidity reading of 66%.  I was hoping/expecting humidity to be more like 55-60% this morning, but it's not the case.  There was no rainfall overnight, none during the past 24 hours, and none in the past four days.

We can expect bright sunshine again this morning, but with pretty much all of the same factors in play that we've been dealing with all week, it's likely that there will be some cloud development happening well before noon.  It does look like average humidity will be a bit lower today than yesterday, so I am hopeful for a greater proportion of sun to clouds.  Although our lower-level pattern remains rather stagnant, there is an increasingly brisk west-northwesterly flow developing aloft which should continue to incrementally chip away at the lingering moisture here at the surface over the course of the coming several days. 

There will be some significant cooling occurring in the mid- and upper-levels of the atmosphere by Sunday, and although computer models aren't showing much precipitation development -- due to that marginal instability -- I wonder if we might see a couple of random (mainly light) showers along the Dhauladhars over the weekend.  Not a huge threat, but something to keep in mind.

Depending on the interplay between sun and clouds into early next week, the arrival of a cooler air mass could translate into temperatures dipping a few degrees.
