A stronger, upper-level system (low pressure) will develop and gain momentum over Montana and Wyoming on Sunday.  It looks like there is a good amount of data showing it will move southeast in our direction early next week.

Importantly, a foundation of cold air and possible storm track will already be laid-out in terms of where this next system may make its move.  Even though the first system (this weekend) won't impact us other than delivering flurries and cold air, it may be responsible for laying out a favorable storm track based on how it does the dirty work in carving out a fairly large dip in the jet stream allowing for this second system to dive south and east in our direction.

Because of this, the newest 12z GFS (forecast model) has identified a chance at some snow coming down across our entire area around next Tuesday/Wednesday.  It's quickly becoming obvious to me that this will be something to keep an eye on over the weekend.

I always keep in mind that these upper-level lows are a bit unpredictable, but the interesting thing is that: 1) upper-lows carry cold air and dynamic cooling potential with them as they move into any given area... 2) it looks as if there will be (at least) some cold air in place at or near the surface, which is very important in determining precipitation type and 3) this looks like a fairly significant piece of energy in the upper-levels capable of generating more than light rain or light snow shower/flurry type precipitation.

Of course, this system could move a bit further north which would keep us on the warmer, rainy side of the storm.  On the other hand, these upper-lows carry a lot of cold air with them and it could track just south of us (as shown on the maps at right) which would leave many of us in the snow-zone.

Stay tuned in the coming days as we hone in on timing and what sort of track this one will take.
