A Bit of Warmth, then Another Wintry Potential

Afternoon everyone.

After seeing several days of below average temperatures, the end of this week will feature temperatures reaching from average to slightly above average as we close off this month and into New Year's.  A great time to do some outdoor activities, whether it be bike riding, jogging, yard work, or simply spending time with the family somewhere without having to worry about bundling up haha.

Of course, the warm up will only last a few days and we will be back to seeing colder conditions again.  In fact, there is already another threat for a potential winter event around the end of the first week of January.  Euro is showing what appears to be a developing system traversing through the SW in the 8-10 day outlook while having a retrograding block.  We also have some pieces of northern energy, so there is a chance that phasing could occur at some point.  Usually in the case of southwestern lows, retrograding ridging occurs in Canada and the cold gets shunted southward and a disseminated baroclinic zone in the Gulf.  Compared to GFS, there is quite a notable difference with how the vortex is handled, and in this case, makes a world of a difference when dealing with UL energy the outcome of an event:
Definitely as we continue on, there will be more data to look at and I will be keeping a close eye on this with the potential.  More to come later.  Have a great day. 

EDIT: 12z Euro looking similar to what it depicted with our last system several days out.  Hmm.......
