our warmest night... (am.19.jun.15)>

We have hazy but generally clear skies as the sun comes up this Friday morning.  And for the first and only time this season and year, I'm recording an overnight low above 70ºF -- the temp dropped to only 70.2F (21.2C) just before dawn.  There has been no rainfall to report.

Most of northwest India is still under the influence of a big ridge of high pressure which is centered over Iran.  This weather feature has kept us dry and stable for the past three days, though we've still had to contend with a daily build-up of clouds along the mountains.  It's also delivering one of our warmest periods of the whole summer season, though increasing humidity and those mountain clouds have kept us from reaching the season's high of 89.4F (31.9C) which occurred back on the 23rd of May.  But there's still a chance of that happening either today or tomorrow (Sat), depending on the interplay between sunshine and clouds.

There are some dramatic changes on the way, however, and those changes should be occurring rather quickly over the weekend.  As we've already been talking about, the first significant surge of rich tropical moisture of the year will be creeping in from the south-southeast -- the effects of which should be quite obvious by Sunday.  Our humidity readings the last several days have been mainly in the 40-50% range, but they should rise much higher than that as this tropical air moves in -- while also giving us a much better chance of some waves of showers and thunderstorms.  The models are showing this juicy air mass remaining with us for most of next week, so it looks like we're going to be getting our first taste of the approaching monsoon.  Stay tuned as we follow what happens...
