brief instability... (pm.27.apr.16)>

Wednesday's stats:

Low temp: 64.0F (17.8C)
High temp: 81.3F (27.4C)
Rainfall: none

We've had two totally different weather scenarios today -- nearly full sunshine this morning with temperatures warming rapidly, then a transition to mostly cloudy skies by just after 2:00pm, with gusty winds and temps dropping a few degrees.  Despite that explosion of convective cloudiness over the mountains, there was never any real shower activity here in McLeod proper... and if there was any thunder, I didn't hear it.  Satellite pics indicate some genuine thundershowers not far to our northwest, however.

The last couple of days we've been talking about some wiggling and rippling coming through in the upper-level flow, and that is indeed what we're seeing right now -- some moderate instability due to weak rotation aloft and some slightly cooler air up there as well.  BUT -- this is a very dry air mass we're dealing with, and even with the instability, there just isn't much moisture to translate into significant rainfall.  Let's see if we can still come up with at least a light shower tonight or Thursday.

High pressure will build back in late tomorrow, and last through most of the weekend.  That will allow us to resume our warming trend, with the highest temps of the season and the year still in the forecast.  An isolated random thundershower is possible during the PM hours, but it looks like we'll have to wait until either Monday or Tuesday of next week to get a taste of some better chances of measurable precipitation.
