chronically unstable... (pm.21.may.17)>

Sunday's stats:

Low temp: 58.1F (14.5C)
High temp: 75.9F (24.4C)
Rainfall: 0.20" (5mm)

It is mostly cloudy this evening, but at least it's quiet and pleasant now.  We had quite the rocky and turbulent afternoon, with rapidly increasing clouds, gusty winds and falling temperatures during the noon hour, thunder right around 2:00pm, and then a period of thundershowers accompanied by more gusty winds and very cool temps between roughly 3:00 and 4:15pm.  There was some sunshine during the morning, but it was the dim/filtered kind of sun, due to lots of high clouds in the area.  My high temp was the coolest I've recorded since the 4th of May.

A weak but broad area of low pressure in the upper-levels of the atmosphere is centered right along the Punjab/Pakistan border right now, and is expected to move only slowly eastward during the coming 24 hours as it gradually dissipates.  That means we've got more unstable weather in the forecast through tomorrow -- with more development of scattered showers and thundershowers quite likely from northern Pakistan into Jammu & Kashmir and Himachal Pradesh.  By tomorrow night into Tuesday there should be some semblance of stabilization occurring, but all throughout the coming week our atmosphere is going to remain marginally unsettled, with the risk of an isolated thundershower or two not out of the question.

We should remain cooler than normal for the latter part of May for another day or two, but it's still looking like a fairly dramatic warming trend will be underway during the latter half of the week -- and that could take us back above seasonal norms/averages by Friday or Saturday.
