brief cooling ahead... (pm.19.nov.13)>

Tuesday's stats:

Low temp: 53.6F (12.0C)
High temp: 61.5F (16.4C)
Rainfall: none

The sky is clear again this evening, after a day which featured sunshine and some fairly extensive patches of mid- and high-level clouds during the mid-morning into the mid-afternoon hours.  Those clouds kept temps from warming as much as expected -- but still, it was the third day in a row that I've recorded 60F or higher at my spot in the upper part of town.  So -- we remain on the plus side of average for this time of year.

That burst of high cloudiness today was evidence of some continued warming which is occurring in layers of the atmosphere just above us -- while cooler air remains trapped in the lower elevations below us.  This is a classic winter season inversion which actually delivers colder night-time temperatures further downhill than we're experiencing up here at the 5500-7000ft elevation.

An upper-level disturbance and associated batch of cooler air is still poised to swing across our area tomorrow (Wed) into Thursday.  Although there could be a few clouds accompanying this system, it will probably arrive and then depart virtually unnoticed -- apart from ushering in some slightly cooler air.  That brief cooling trend will then reverse itself as the weekend arrives, with temperatures rising a few degrees above normal yet again.  Looking further ahead, there is evidence of some potentially unsettled weather during the early part of next week, but a well organized storm system doesn't look likely at this point.
