Friday's stats:
Low temp: 41.4ºF (5.2ºC)
High temp: 52.6ºF (11.4ºC)
Precipitation: none
An intensifying upper-level low pressure circulation is just now starting to move into northwestern Afghanistan, and will be the main driver of our weather scenario over the weekend. A very cold pool of air is associated with this system, especially in the middle and upper levels of the atmosphere, and that's going to continue to destabilize our air mass, and bring a better and better chance of various forms of precipitation as we head into late Saturday and Sunday.
I've mentioned that this system isn't tapping into much of a supply of deep moisture, but with the upward lift and much colder air aloft moving across the mountains, we're going to see some significant areas of rain and snow develop. The latest data would suggest that the most significant precipitation (perhaps in excess of a half-inch, or 1.2cm) in our immediate area would occur between Saturday evening and late Sunday night. That translates into 5-6" of snow, IF temps cool down enough for that transition to occur. Heavier amounts are likely in the higher elevations above.
There are always all kinds of changes that can/could occur as a storm system like this makes its approach... check back for updates during the next couple of days...
