SYNOPSIS FROM THE PHOENIX OFFICE
A large Pacific low pressure system will move into the desert Southwest later today through the weekend. This system is forecast to bring windy weather today followed by much cooler conditions and a threat of showers and thunderstorms Friday and Saturday. The low pressure system will begin to move East Sunday followed by dry and much warmer weather next week.
Very interesting weather!
A massive Pacific low pressure system off the Central and Southern CA coast will partially move inland today.
Meteorological data suggest a moderately strong vertical motion field developing over Southeast CA and Southern Nevada. Low level winds will subsequently respond in a big way becoming South 25 to 40 mph with areas of attendant blowing dust.
SYNOPSIS FROM THE SAN DIEGO OFFICE
A low pressure system will arrive in Southern California today and move slowly through the region Friday through the weekend. It will bring cool and cloudy weather with showers and brisk winds this afternoon and evening. The greatest chance of showers will be tonight and Friday with a few thunderstorms possible. Fair and warmer weather will return next week as high pressure moves over the west coast.
A low pressure trough will move into Southern California today. Winds will develop in portions of the mountains and deserts this afternoon through tonight. Some gusts will top 50 mph. The chance of showers will gradually increase this afternoon and evening and become likely tonight through Friday. Latest models indicate enough instability for a slight chance of thunderstorms this evening through Friday as well but the greatest chance will migrate inland during the day Friday.
