|SYNOPSIS FROM THE SAN DIEGO OFFICE
Strong northwest flow aloft will bring strong winds to the mountains and deserts this afternoon through tonight. Fair and warm weather is forecast through the weekend with some offshore flow and local northerly winds. High pressure will continue to bring fair and warm weather next week. Brisk northwest flow aloft will increase winds in the mountains and deserts this afternoon through tonight. Top isolated gusts will exceed 60 mph, but widespread gusts over 40 mph are expected. That could stir up some dust in areas of the desert.

SYNOPSIS FROM THE PHOENIX OFFICE
A series of mainly dry Pacific weather disturbances will move across the western states through early next week. These systems will keep afternoon temperatures near or slightly below normal, along breezy afternoons and evenings. One stronger disturbance on Friday will likely bring windy conditions and has the potential to produce a slight chance of afternoon showers over the eastern Arizona mountains. Winds will again be breezy today, but gusts should mostly remain below 25 mph. Similar conditions are expected for Thursday as dry northwest flow continues. Another windy day is likely on Friday with a high likelihood of some areas being under Wind Advisory. The strong winds and lowering humidities on Friday will likely bring dangerous fire weather conditions once again.
