SYNOPSIS

The thick band of mid and high level moisture and clouds will move east of the area by early this afternoon. High temperatures will be a few degrees cooler today, followed by a warming trend into next weekend with widespread moderate or greater HeatRisk for the coast and valleys for Thursday through Sunday with near record warm overnight temperatures for Friday through Sunday.

SHORT TERM (Today through Wednesday)

Mid and high level moisture from former Hurricane Odalys continues to stream northeastward and across about the southeastern half of southern California early this morning. A band of mostly light showers is across about the southeastern third of San Diego County with hourly rainfall of less than one-tenth inch per hour. The greatest totals since Sunday are in the far southern San Diego County valleys and mountains with 0.15 to 0.25 inch through midnight. The western edge of the showers will move slowly to the east overnight with the band of thicker mid and high clouds decreasing from the northwest during this morning.

High temperatures will be a few degrees cooler today, followed by warming on Tuesday and greater inland warming on Wednesday. With the warming, high temperatures on Wednesday will range from around 80 near the coast to the upper 80s to mid 90s for the Inland Empire with the lower deserts in the upper 90s.

LONG TERM (Thursday through Sunday)

High pressure aloft will continue the warming trend into next weekend with only slight cooling on Sunday. Widespread moderate or greater HeatRisk is expected for the coast and valleys for Thursday through Sunday with widespread major HeatRisk for inland coastal areas into the western San Diego County valleys for next weekend.

High temperatures for next weekend will range from a few degrees above average for the lower deserts to as much as 12 to 18 degrees above average for the coast and valleys in San Diego County. High temperatures for next weekend will range from the 80s near the coast to the mid 90s to around 100 for the inland valleys with the lower deserts around 100.

For next weekend, low temperatures for the Orange County coastal plain, and for the coast and western valleys in San Diego County will be mostly in the lower to mid 70s. For Friday through Sunday, there could be several records tied or broken for record warm low temperatures, mostly for coastal and valley locations. The existing records for some of those locations was from 1997.

AVIATION

281130Z...BKN middle and high clouds above 9 kft MSL will continue to exit to the southeast this morning. Very patchy low clouds based at around 1500 feet MSL at the coast are expected through 17Z, but any cigs at coastal airports would be brief and intermittent. Some cumulus based at around 10 kft should develop over mountains and deserts after 20Z into tonight. Patchy coastal low clouds based at 1200 feet MSL to develop after 03Z, but random and intermittent.

MARINE

Northwest winds gusting to 20-25 knots in the outer waters this afternoon and evening, generating choppy seas. The Small Craft Advisory contains more details. No hazardous marine conditions are expected Tuesday through Friday.

BEACHES

Southwest swell from former Hurricane Odalys will combine with south- southeast swell from Hurricane Polo today. This will elevate surf with expected sets up to 6 feet today in northern Orange County. There is a high risk for strong rip and longshore currents through Tuesday. In addition to elevated surf, high tides will peak at 6.8- 7.1 feet during the late mornings today through Wednesday, highest on Tuesday. High tides and elevated surf will combine to generate minor coastal flooding in low lying areas and coastal erosion. A Coastal Flood Advisory is in effect through Wednesday afternoon.

Please note - mentioned tide predictions in the Advisory have been adjusted to reflect actual measured tide observations.

SKYWARN

Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions.
