a fresh warming trend... (am.16.jun.15)>

As mid-June mornings go, this is a nice one.  We have partly cloudy skies just as the sun rises over the mountains, and the temperature and humidity readings are very comfortable for the season.  I'm recording a low temp of 63.9F (17.7C), and there has been no precipitation since last report.

Our temperatures dipped below normal on Saturday, and have remained there ever since. We've had a few days of impressive north-northwesterly flow in the middle and upper levels of the atmosphere that brought in some unseasonably cool temperatures, along with a couple of periods of healthy showers and thundershowers.  The pattern is again shifting, however, as a strong ridge of high pressure builds in from the west.  A much warmer air mass will again ease into our area during the next 24-48 hours, and there could be enough warming aloft to diminish the cycle of instability that has been going on the last several days.  By this time of year it's asking a lot to totally ignore the risk of a mainly PM thundershower somewhere around the area, but I think we will be seeing a return to a greater percentage of sunshine, dramatically warmer temperatures, and lower shower/thunder chances -- mainly between Wednesday and Friday.

The data is pointing to the most uncomfortable combination of heat and humidity that we've seen yet this year by the middle and latter parts of this week -- let's see if that materializes or not.  THEN, the potential for some substantial rain gradually enters the picture over the weekend into early next week, as some deeper tropical moisture begins to come knocking...
