an active and changeable pattern... (pm.24.feb.19)>

Sunday's stats:

Low temp: 43.7ºF (6.5ºC)
High temp: 51.6ºF (10.9ºC)
Precipitation: none

We're completing another day featuring lots of variability between clouds and sunshine all throughout, but with no precipitation at all for the second day in a row.  The high temp was a few degrees cooler than on Saturday, as we were expecting.

The main feature of our current weather pattern centers on a broad area of low pressure in the upper atmosphere over central Asia, which is expanding and sinking toward the southeast.  One of the coldest air masses of this entire winter season is associated with this system, and will keep our temperatures unusually cool during this coming week.

There is also a significant batch of moisture that is being pulled in our direction from the Arabian Sea -- most of it arriving between late Tuesday and Wednesday evening.  The data this evening is not looking as impressive as it was 24hrs ago, as the main trajectory of that moisture seems to be directed just to our east-southeast -- into Uttarakhand and Nepal.  Even so, it still looks like we've got a decent chance of some light to moderate accumulations of snowfall in our general area during that late Tuesday through Wednesday time frame.  Stay tuned as we watch if this all comes together, or not.

Further ahead... yet another storm system with the potential to produce significant precipitation will threaten us in about a week from right now, by the end of the first weekend of the new month.
