Area Forecast Discussion National Weather Service San Diego CA 202 PM PST Mon Jan 18 2021

SYNOPSIS. The time has come for a change in the weather across our region. Much cooler conditions can be expected with gusty Santa Ana winds and periods of showers as a low pressure system digs southwest over our region. The winds will strengthening tonight from the north across northern areas then become more easterly and spread southward into San Diego County late Tuesday and continue into Wednesday. Precipitation is also possible for late Tuesday into early Thursday. There will be warming for Wednesday and Thursday with drying on Thursday. Low pressure systems from the northwest may bring additional precipitation with cooling for late Friday into Saturday and again into early next week.

DISCUSSION. FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE . SAN DIEGO . WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES .

SHORT TERM (Today through Thursday).

Current visible satellite imagery showing some areas of clouds and fog off the beaches this afternoon with offshore wind gusts 25-35 MPH for passes in northern areas and the Inland Empire. An upper level high pressure system will begin to gain strength in the Great Basin today and protrude into Southern California, brining dramatic height falls. This will accompany a tightening surface pressure gradient to bring strong and damaging Santa Ana winds across the region from north to south. Strong north and north east winds gain momentum tonight, where parts of the Inland Empire to all areas of Orange County seeing very gusty winds and elevated to critical fire weather conditions. Gusts in these valleys may reach up to 65 MPH, locally higher. Parts of these areas are also under Red Flag and High Wind Warnings, so please take a look at those products for the latest details.

As the low pressure system pushes southwestward off the northern Baja coast, the back side of the system has the potential to bring in some moisture from the south and east starting later on Tuesday for the mountains and lower deserts. Winds will also start to shift to a more easterly direction on Tuesday, creating damaging winds from the San Diego mountains all the way to the coast. Please see the High Wind Warning product for these areas, as local WRF guidance shows widespread wind gusts near 60 MPH possible (locally higher in windiest spots).

The area of low pressure will continue to move slowly eastward across the Baja, with another moisture surge possible early Thursday before it departs. This moisture surge may bring some light showers from the coast into the deserts. Rain totals will be mostly 0.75 inches or less for mountain areas and closer to 0.25 inches or less for the lower deserts. Areas west of the mountains may see some light showers amount to close to one tenth of an inch, highest in San Diego County. As far as the fluffy white snow goes, we won't be seeing too much in the way of that frigid fun as snow levels rise closer to 7,000 feet by Wednesday afternoon. Mostly a dusting to a couple inches near that level with 4 inch totals over 8,000 feet.

The coolest day will be Tuesday with much of the area a bit below average. Temperatures will peak Wednesday with many 70s for the coastal valleys and slight cooling by Thursday with mostly dry conditions as our low pressure friend departs.

LONG TERM (Friday through Early Next Week).

The storm will finally not be hitting us on the way out, as we will prop it open for a troughing pattern to stick around through much of early next week as ensembles usher in Pacific storm systems into the State. Low pressure systems from the northwest could bring more widespread precipitation for late Friday into Saturday, as ensemble guidance looks rather promising. Another reinforcing wave may come into the area early next by Monday, with some more rain and mountain snow. This period will also feature much cooler temperatures than we have been seeing as well, where many mountain and desert locales will stay in the 50s and low 60s.

AVIATION. 182100Z . Patches of low clouds and fog at the immediate coast this afternoon. Cloud bases are about 200 ft MSL and visibility 1-2 miles, locally less than 1 mile. Low clouds and fog is likely vcnty KSAN but may not impact runway complex. More widespread low clouds with bases 500-800 feet MSL and areas of vis 3-5SM developing after 02Z Tuesday and spreading locally inland through 14Z Tue, mainly in San Diego County. Otherwise, mostly clear with unrestricted vis through tonight.

Strong northeast winds 20-30 kts will strengthen tonight through Tuesday. Weak to moderate up/downdrafts and LLWS west of the mtns today will become stronger tonight into Tuesday including vcnty KSBD and KONT.

MARINE. Patchy fog with low visibility will continue this afternoon over portions of the coastal waters. Gusty northeast to east winds will develop across portions of the waters Tuesday into Wednesday with wind gusts reaching 25 knots and possibly 30 knots at times. Otherwise, no additional marine weather hazards are expected through Friday.

BEACHES. Long-period west-northwest swells will produce elevated to high surf and dangerous swimming conditions through Tuesday. Check the High Surf Advisory, Beach Hazards Statement and the Surf Zone Forecast for details.

FIRE WEATHER. A Red Flag Warning is now in effect areas of the Inland Empire, Santa Ana Mountains and Inland Orange County as north to northeast winds will continue to be gusty today and be strongest for early Tuesday. These winds will then become more easterly and spread southward into San Diego County late Tuesday and continue into Tuesday night and Wednesday.

The strong winds and lowest humidity will coincide on Tuesday for the Inland Empire, the Santa Ana Mountains, and inland Orange County with areas of northeast winds 25 to 35 mph with gusts 60 mph. Isolated gusts to 75 mph in the Inland Empire below the Cajon and San Gorgonio Passes, and near the coastal foothills of the Santa Ana Mountains. The humidity for these areas will fall to 15 to 20 percent on Tuesday. Humidity for theses areas will increase a bit Tuesday night and Wednesday. Winds will continue to be very gusty from the mountains to the coast in San Diego County on Tuesday and Wednesday, so any fire starts may spread rapidly.
