seasonal battles... (pm.05.mar.19)>

Tuesday's stats:

Low temp: 40.6ºF (4.8ºC)
High temp: 51.4ºF (10.8ºC)
Precipitation: 0.20" (5mm)

What a great early-mid morning we had... with brilliant sunshine and milder temperatures.  But -- with very cold air aloft, there was literally an explosion of cloudiness during the hour before noon, with the first round of sprinkles and light rain showers getting going right at mid-day.  That led to a healthy round of rain showers and thunder between about 12:30 and 2:15pm... followed by clearing and another dose of sunshine during the mid-late afternoon... and then yet another round of showers/thunder during the evening between 5:00 and 6:30pm.  All the while, the sun was shining not far downhill.

A massive temperature disparity exists along the western Himalayas... with very cold air entrenched to our north-northeast, and milder/warmer air building to our south.  We are stuck right in the middle, which means we are in the zone of major instability.  This situation is not going to ease up in the near future, so it looks like we are still in line for a wide variety of weather conditions -- sun, clouds, the threat of rain/thunder showers, as temperatures attempt to very slowly moderate.

We may break into some stable and significantly milder and drier weather (temporarily) over the weekend... but the pattern remains volatile and changeable until at least the middle of the month.
