weekend variability... (pm.09.may.14)>

Friday's stats:

Low temp: 61.0F (16.1C)
High temp: 76.1F (24.5C)
Rainfall: trace

A beautiful evening is underway, with mostly clear skies apart from some lingering/dissipating clouds along the mountains here at sunset.  Sunshine was dominant until the early afternoon hours, but then we had a very impressive build-up of clouds, along with thundershower development just up-mountain from us which kept our skies looking threatening from the mid-afternoon unto the early evening.  I never witnessed anything other than a few random sprinkles of rain -- mainly between 3:00 and 4:00pm -- but thunder was rumbling for a couple of hours.  Temperatures were comfortably warm.

It still looks like we have better chance of some significant shower and thunderstorm activity around the corner, though it will probably hold off until the weekend is almost over.  General instability during the PM hours will likely set off another round of thundershowers tomorrow, but most of it will probably remain in the mountains to our north and east again.  But during the day on Sunday we could see a better and better chance of that thundershower action affecting us further downhill, with scattered showers and thunderstorms quite likely on Monday and Tuesday.  A strange-looking upper-level circulation dropping in from the northwest will encounter our warm and rather moist air mass, providing us with those better rain chances into at least the middle of next week.

I think our recent pleasant and seasonably warm temperatures will be replaced by some chillier-than-normal temps by Sunday night, and especially by Monday.  Right now it looks like we can expect that cooler weather to hang around for the majority of next week, with highs not much above 70F (21C) for a few days.
