A Look at the Next Two Potentials of Snowfall

December 27th, 2012 at 4:26 pm by under Chad's WLFI Weather Blog

It is a bit of a complicated forecast for Friday night-Saturday.

There is a nice system of dynamic & frontal forcing producing accumulating snow to our northwest, despite lack of moisture.  Meanwhile, very, very active subtropical jet (been a big factor in all of the monster storms this season) is roaring through the southern Plains with deep Pacific moisture.  Additionally, deep low-level moisture is pooling in Texas & Louisiana & surging northward from the Gulf of Mexico.

The upper system in the polar jet & abundant moisture in the subtropical jet need to merge into our cold air to get a good snow up here, as the great dynamics for snow (even without much moisture) will tend to pull away from us.

The merger is expected to occur east of here, shunting the snowfall east & southeast of here.

Nonetheless, some snow is possible Friday night-Saturday morning, but if that merger happens more to our south/southwest than southeast it will be much more in the way of snowfall.

We need to keep an eye on a system with abundant moisture & dynamics for early next week.  This may bring some accumulating snow (at least minor).

    Chad, are you looking at any major cold coming towards the middle or end of January? Also how about the weather pattern? Do you believe tht we will have these systems coming in every week?
