warmest since september... (pm.22.apr.15)>

Wednesday's stats:

Low temp: 59.5F (15.3C)
High temp: 78.0F (25.6C)
Rainfall: none

We're in the midst of the warmest days of the year thus far -- my high temperatures recorded in the upper part of town during the last three days have been warmer than anything we've experienced since last September.  Today was pretty much perfect, with lots of sunshine, low humidity, and just a few clumps of cumulus clouds over the mountains during the PM hours.  I did hear one lone rumble of thunder up there around 4:20pm.

There were a few isolated thundershowers along the Himalayan ranges from Kashmir southeastward into Nepal today -- but the highest concentration of that activity was in Nepal, where there is a more sufficient moisture source.  We've had drier air working its way into northern India during the past 24 hours or so, and that has diminished the fuel supply for thundershowers, despite a marginally unstable atmosphere.  We'll probably be looking at about the same scenario tomorrow (Thu), with a slight increase in the risk of a thundershower on Friday.  Otherwise, there's probably going to be plenty of sunshine ahead.

Subtle changes which include an increasing amount of moisture creeping in from the southeast, warming aloft, and a bit of upper-level energy moving in from the west will all team up to bring us a slowly changing pattern by early next week.  In fact, we may be dealing with a better chance of some periods of showers and thunderstorms by Monday and Tuesday.  Temperatures in the meantime won't be swinging very radically in either direction... remaining very comfortable for the most part.
