on the verge... (am.08.apr.15)>

At least at this moment, there are only a few scattered clouds dotting the pre-sunrise sky -- so we should be starting off the day with a good amount of sunshine.  As expected, there was more of that off-and-on rain shower action overnight, and my rain gauge shows an additional 0.29" (7mm) since about 9:00pm.  I'm recording a low temp of 45.0F (7.2C), but it's around 49F/9.5C currently.

We're finally on the verge of what will hopefully be a turn to some dramatically better weather conditions.  Ever since last week's very stormy pattern, we've been stuck underneath an upper-level flow that has been allowing unseasonably cold air to continue sagging into northern India -- with downright frigid air in the upper atmosphere keeping things very unstable.  The computer model data has been struggling with this pattern... tempting and teasing us with gradually warming temperatures which so far have not materialized.

Anyway, a complete overhaul of the general pattern will kick in starting today, with some major changes expected in the days ahead.  We could still see some random shower development today, but uniform warming throughout all layers of the atmosphere should put us on the road toward greater stability.  Dramatic warming and much more sunshine is expected on Thursday and Friday, though there could be an isolated thundershower during the afternoon hours somewhere along the Dhauladhars.  That risk of an afternoon thundershower increases a bit on Saturday and Sunday -- but we'll be dealing with temperatures that are more appropriate for the season.  Hopefully we can finally get on with our transition into more reliably summertime weather during the coming week or so.
