.SYNOPSIS...Dry weather with above normal temperatures will persist
through early next week. Near record high temperatures will be
possible today and tomorrow. A passing weather disturbance will
then cool afternoon temperatures begining Christmas Day of next
week.

&&

.DISCUSSION...The ridge that has been in place over the past few
days has begun to flatten out as a shortwave moves through well to
the north. However surface temperatures don`t respond until early
next week. Record highs will be possible both today and Sunday.
Monday into Tuesday temperatures "cool" 2-3 degrees compared to
over the weekend. After Tuesday a couple troughs will move through
the region. The first moves through Christmas day and will bring
slightly elevated winds and a chance for precipitation (20-30
percent) in the White Mountains. The core of the low passes
through southern Utah and the Four Corners, which keeps precip
chances to the north. The second trough moves through late
Thursday into Friday. There is much greater uncertainty with this
second trough with respect to its speed and depth. Precip chances
are again confined to the White Mountains and generally below 25
percent. Both systems will bring temperatures down compared to the
past few days, but still be 5-9 degrees above normal.

&&

.AVIATION...Valid through 23/00Z.
SKC first half of valid pd, then FEW-SCT thin cirrus AOA 20k ft
moving thru during second half of valid pd. SFC winds mostly
W/NW this afternoon less than 10 kts. Light terrain driven SFC

discussion not updated for TAF amendments.

.FIRE WEATHER...Dry conditions with above normal temperatures

middle of next week will bring cooler temperatures and a chance of
showers to the White Mountains Christmas Day and Friday. Minimum
relative humidity values 10 to 15 percent in the valleys into the
middle of next week, with 15 to 25 percent expected in the higher
terrain. 20-foot winds will mainly be less than 15 mph through
the next week.
