…Severe potentially damaging winds later today and this evening
over the mountains and deserts…

SYNOPSIS FROM THE SAN DIEGO OFFICE
For today a deep low pressure trough moving across the Great Basin will bring strong and potentially damaging west winds to the mountains and deserts. Cooler Friday behind the trough with winds shifting to the northeast. High pressure rebuilding over the region Saturday will bring sunny and warm weather this weekend. Cooler early next week as another trough moves in from the northwest

As the low shifts to the east winds will shift to the north late tonight and into Friday morning. There may be another period of strong winds through Friday morning, although not nearly as severe as what we are expecting with the WNW. Northerly winds will continue through Friday night although not nearly as strong but a wind advisory may be necessary to cover this period after the threat for high winds has ended.

SYNOPSIS FROM THE PHOENIX OFFICE
A strong low pressure system will produce windy conditions today along with much cooler temperatures Friday. Isolated precipitation is possible across the higher terrain of eastern Arizona Saturday as the storm lingers. Warmer conditions will then return Sunday and into early next week as high pressure again builds across the region.
