|Imperial County Weather Synopsis|
|SYNOPSIS FROM THE SAN DIEGO OFFICE
Fair and warm weather is expected today with high clouds. A Pacific low pressure system will bring showers and possible thunderstorms Friday. Continued moisture could result in a few mountain showers Saturday. Another trough will arrive Sunday and will bring cooler weather and scattered showers. A cool but dry holiday on Monday before the next trough arriving Tuesday with more showers.High clouds have thickened overhead and any coastal low clouds trying to form underneath them will be patchy at most this morning. It will be fairly warm today despite the thickening high clouds. We have three shortwave troughs that will move through Southern California in the coming week. The first one will arrive tonight and Friday. It has a pretty impressive moisture plume that will hit central California with good rains, but the edge of the moisture dramatically drops off just south and east of LA. Favorable orographic flow could wring out over an inch of rain in the San Gabriel and San Bernardino Mountains, but far lesser amounts are expected in the lowlands, especially as you head south into San Diego County.
SYNOPSIS FROM THE PHOENIX OFFICE
Strong high pressure over the region will lead near record temperatures today. A weather system moving through California on Friday will bring a chance of showers to southeast California along with slightly cooler temperatures. High temperatures this weekend will remain well above normal, but a gradual cool down will occur through the middle of next week. Near to slightly above normal temperatures are likely for much of next week with the mostly dry weather continuing.
