|Imperial County Weather Synopsis|
|SYNOPSIS FROM THE SAN DIEGO OFFICE
A low pressure trough moving by to the north will bring cooler and breezy weather today, along with a slight chance of light showers this morning west of the mountains and areas of strong winds in the mountains and deserts this afternoon and evening. Fair and seasonal weather will continue this Friday through Monday. The next trough of low pressure to the north brings our next slight chance of showers around Tuesday, followed by dry and warmer weather.
SYNOPSIS FROM THE PHOENIX OFFICE
High pressure aloft will dominate the overall weather pattern across the Desert Southwest into next week. This will bring above normal temperatures and continued dry conditions. Lower desert highs will reach into the upper 80s to lower 90s each day under mostly clear skies. A deep Pacific trough currently moving through northern California into the Pacific Northwest will quickly progress to the northeast today. Southern fringes of the trough will remain well to our north keeping the Desert Southwest under dry southwesterly flow aloft. A tightening surface pressure gradient today in response to strengthening high pressure to our west will bring a breezy to windy day to southeast California and southern Arizona. Most areas will see gusts close to 25 mph this afternoon/early evening with the strongest gusts of 35-40 mph across far southwest Imperial County.
