(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 ksgx 172118 afdsgx area forecast discussion national weather service san diego ca 118 pm pst Sun feb 17 2019 Synopsis A disturbance dropping south along the coast will move over socal through tonight with gusty westerly winds and showers of rain and mountain snow. The snowfall will add up in the mountains, and the combination of locally heavy amounts and strong westerly winds will make for dangerous winter travel conditions there this evening. At lower elevations, it will mostly be light rain showers that could be briefly heavy. Fair skies return on Monday, but continued cold. Slight warming is on tap for Tuesday and Wednesday ahead of another cold shot later in the week, accompanied by more showers of rain and mountains snow. Discussion For extreme southwestern california including orange... san diego... Western riverside and southwestern san bernardino counties... Winter storm warnings in effect for the mountains with a sharp deterioration in weather conditions by late this afternoon. More cold this week with the coldest airmass of the season possible by Thursday and Friday. Satellite imagery at midday shows clouds backed up against the coastal mtn slopes, with more widespread cloud cover advancing from the nw. Farther to the north, an extensive open-cell CU pattern offshore, suggestive of strong cold air advection, was moving south along the coast. Radar showed small, weak, patchy echoes along and west of the mts moving rapidly SE with stronger echoes near the channel islands. Rainfall observations over the past 3 hours were mainly in san diego county and around one-tenth of an inch or less. Based on sfc observations, the snow level was near 4400 ft in san diego county. Moderate onshore sfc pressure gradients still were trending onshore, supporting west winds of 25 to 35 mph with peak gusts to near 50 mph in windier mtn areas. Along the coast, winds were gusting to around 25 mph at noon. The 12z miramar sounding has a pw of just over 1 2 inch with considerable instability below 10k ft. This is forecast to persist and will enhance shower development headed our way later today. Due to the strong flow in the mid-levels of close to 50 kts, these showers will move rapidly, minimizing precip accumulation at lower elevations. Meantime the perpendicular trajectory into our mountain ranges will enhance accumulation there. Even though the san bernardinos are a transverse range, significant precip amounts are indicated there as well, mainly due to greater elevation and proximity to the developing mid-level circulation and a lower snow level to enhance liquid to snow ratios. Please check the laxwswsgx for detail on snow levels and amounts. Based on the latest hires models... Precip will increase between 3 and 5 pm pst. At that time, the more concentrated precip area up the coast will arrive with more widespread showers. It may not be until around 5 pm that this reaches san diego proper. Expect light amounts of rain overall, punctuated by brief heavy spurts of rain and even a few ice pellets. Winds will be brisk today, but take a leg up late this afternoon and evening with strong gusts expected most areas by evening. In the mountains, they will exceed high wind criteria at times with gusts to 65 mph or more on the ridges. This is supported by strong 850 mb winds of 35 to 50 kts. In the deserts, rotors may develop near the foothills resulting in strong, shifting wind gusts. A broad trough over the west will expand farther south today as a shortwave and associated jet streak drop south along the west coast and round the base of the trough tonight. Instability and sufficient moisture will interact with the lift associated with this feature to generate significant snows over the mountains of southern california. The strong upslope flow into the mts will enhance lift, while the cold air ensures snow-levels remain suppressed. Strong and gusty westerly winds are forecast as well, so winter storm warnings are in effect through tonight. The energy with this wave will slip east on Monday, and despite fair skies and strengthening february sun, the cold trough over the area |
will ensure a cold presidents day, with daytime temperatures well below normal. Only minor warming is on tap for Tue Wed under continued cold, northerly flow aloft. By Thursday, another shortwave will drop south along the west coast, amplifying the trough and cold air advection into socal. Ahead of this, once again, some moisture will be drawn in off the pacific, setting the stage for showers of rain and mountain snow. Latest gfs ec guidance suggests the system will remain mostly land-locked, limiting precip amounts. The GFS closes off a low near needles, while the ECMWF continues the digging, both with strong cold air advection indicated for Thursday. The ECMWF is the most aggressive with the precip and suggests very low snow levels as our 1000-500 mb thickness falls to between 526 and 528 dm. This could bring the lowest snow levels yet this winter and a possible widespread frost and or freeze. After Friday, it looks like the cold air will retreat back to the north as flow aloft becomes more zonal. Expect a fair, dry, and warmer period by next weekend. Aviation 172100z... Coast valleys... Sct-bkn035-050 with tops to 8000 ft. Scattered shra today, most widespread this afternoon and evening with vis 5 miles and CIGS 020 in the heaviest showers.

Marine Gale warning in effect through 10 am Monday for strong wnw winds 20- 30 kt with gusts to 35 kt through Monday morning. A mix of steep waves westerly swells will result in hazardous boating conditions today and tonight. Winds and waves will decrease to 10-20 kt with gusts to 25 kt on Monday. Beaches A beach hazards statement is in effect through 4 pm today for elevated surf, strong rip currents and minor coastal flooding during the times of morning high tide (6.3 ft at ~7 am). Large wnw swells of 10-12 ft 8-9 sec from 290 degrees will bring elevated surf today, highest in southern san diego county with sets to 7 ft.
