.SYNOPSIS...Dry weather with well above average temperatures
continue up until Christmas Eve night. Then, a brief pattern
change begins as a couple weak and fast moving storm systems move
through Tuesday night through Wednesday, and then Thursday
afternoon through Friday morning. This will bring temperatures
closer to late December averages as well as some light rain and
snow.

&&

.DISCUSSION...High pressure ridge gets flattened over the next
couple days as a couple troughs pass north of us. Only short term
impact will be a bank of mid level clouds moving through Sunday
night into Monday morning which will keep our overnight
temperatures a few degrees warmer than this morning`s readings.
Afternoon maximum temperatures today through Tuesday back off a
few degrees but remain well above average.

Come Christmas Eve night a weak and fast moving system moves
through the area. System looks a little stronger than it did last
night and although once again not a big precipitation maker, it is
conceivable that Kaibab Plateau and areas of the Rim above 6500ft
could see a brief dusting of snow Christmas morning. Temperatures
on Christmas will be about 10-15 degrees colder than Christmas
Eve, but still be on the higher edge of the normal range.

Another system follows on the heels of this one Thursday night
into Friday. This one now looks weaker than previously thought
with lower POPs and little to no QPF. Temperatures remain colder
but closer to December averages.

Early indications are that another ridge builds in by next weekend
with dry weather and above average temperatures returning to the
area.
