A very large and strong ridge of high pressure will bring valley highs 20+ degrees above normal through Thursday.

The ridge has brought very warm temperatures aloft, developing an inversion.  Forecast sounding or profiles of the atmosphere show air temperatures near 60 degrees at 4,000ft!  This will make for warm overnight temperatures in the foothills and mountains for unprotected slopes, as well as poor air quality.

North winds will still be breezy and gusty at times.  Hi-res forecast models are showing highs in the upper 70 with dew points near 10 degrees.  The combination of the air temp. and dewpoint means relative humidity values near single digits.  Any moisture in vegetation will quickly wick away.

We'll stay warm and dry through the next 7 days, with a slight cool-down this weekend.
