.SYNOPSIS...Expect gusty northeast winds and cool temperatures
through Thursday, with Thursday being markedly windier and colder
than Wednesday. Warmer temperatures and less wind return starting on


.DISCUSSION...A weak upper low near Phoenix will slowly drift
southeast tonight and out the state Wednesday morning. Light
convective showers in the center of the low and light stratiform
preciptation in the diffluent area near the White Mtns will both
taper off in the next several hours.

Dry and cool northerly flow will reside over the state Wednesday,
ahead of another strong and dry cold front due Wednesday night and
Thursday. This system will follow a trajectory farther to the east,
but will bring even colder and windier conditions to our area
Thursday and Friday.

Dry northerly flow then dominates into the weekend, although the

Grids and text look fine this evening, high temperatures Thursday
will likely need to be lowered.

through the period. A departing low pressure system will bring light
snow showers to the White Mountains through early Wednesday morning.
A second low pressure system will move into New Mexico by Wednesday
night and Thursday, bringing increased east through northeast winds
and pronounced cooling/drying to the area on Thursday.

Friday through Sunday...Dry weather will continue into the weekend
while high pressure builds over the west coast. Daytime temperatures
will slowly return to average or above average, as easterly winds
