typical stuff... (am.12.apr.13)>

There are some patches of high clouds drifting through, otherwise it's mostly sunny to start our Friday.  Those scattered showers which developed just after sunset last evening fizzled out by 9pm -- and I only recorded 0.02" (less than 1mm) here in the upper part of town.  My low temp since midnight has been 57.6F (14.2C).

There must have been a random pocket of colder air in the higher levels of the atmosphere passing overhead last evening which triggered that surprise round of showers -- just an example of how fragile our air mass can be here along the front ranges of the Himalayas.  The overall weather pattern, however, is expected to remain quiet for the next couple of days.  We'll have sunshine and occasional periods of clouds, along with the off-chance of an isolated/random shower or thundershower (mainly over the mountains), with a little better chance of thundershowers on Sunday afternoon.  Temperatures will remain right in the normal range for this stage of April, and close to the warmest we've experienced all year.

Potentially ominous signs are appearing for Tuesday through Thursday of next week.  Warmer and warmer air building on the plains to our south is going to be overrun by a batch of colder air in the upper-atmosphere sinking southward from central Asia.  Computer models are hinting at some significant thunderstorm development here during the middle of next week... so stay tuned as we watch how that scenario evolves.

The CURRENT FORECAST, as always, is on the tab above.
