area forecast discussion
national weather service san diego ca
627 pm pdt Sun sep 15 2019
After another very warm day today, Monday and Tuesday will be
noticeably cooler with more clouds as a trough of low pressure
moves east across the state. This cooler weather pattern will
persist through the end of the week, keeping temperatures below
average inland, but near late summer normals along the coast. Gusty
westerly winds will peak over the mountains and deserts Monday
night. This prevailing onshore pattern will rebuild the marine layer
and associated low clouds and fog inland nights and mornings.
Discussion For extreme southwestern california including orange...
san diego... Western riverside and southwestern san bernardino
the forecast was updated to add a slight chance of dry lightning for
Monday during the daytime for all areas. The threat is very low at
about 20 percent or less, but nonetheless an incoming weak upper
level disturbance currently over the eastern pacific could trigger
sprinkles and a few low precipitation thunderstorms just about
anywhere tomorrow. No other changes to the forecast at this time.
Previous discussion issued at 114 pm pdt:
at 1 pm pdt... High clouds had thinned over the region but were
extensive offshore and drifting ne. Lower clouds that were visible
over the coastal waters were patchy. The sfc gradient readings we
have are very weak, but trending onshore to the high deserts.
Strongest wind reports were over SW san bernardino county with peak
south winds gusts of 25-35 mph.
The higher clouds are forecast to thicken and lower some on Monday
as some moisture is drawn north from hurricane kiko ahead of a weak
300 mb trough. A few sprinkles are possible, along with gusty and
erratic winds if these showers form. Elevated instability predictors
will be monitored for thunderstorm and dry lightning potential, but
for now the chance looks too small for inclusion in the forecast.
The prevalence of high cloudiness may inhibit much low cloud fog
formation again tonight, but at least patchy low clouds fog are
Higher confidence does exist for relief from the heat though, as an
upper-level trough drops south along the british columbia coast
today, and swings inland across ca on Monday with increasing SW to
west winds, allowing the marine layer to build inland. It will be
noticeably cooler across the entire area with the cooler conditions
prevailing all week as another trough drops south, reinforcing the
onshore pattern over socal.
The ocean sfc temps over the ca bight are currently in the lower
70sf, so the cooling power of the sea breeze will be somewhat muted,|
but still expect daytime temperatures to be running a little below
average after today. Slight warming returns next weekend as the
trough over the west weakens.
151945z... Coast valleys...VFR conditions will prevail through
midnight. Low clouds will redevelop near 08z Monday on the coast,
with bases 400-800 ft msl and tops to 1,500 ft. These will spread 10-
15 miles inland in san diego and orange counties. Sct-bkn high
clouds AOA 20,000 ft msl will continue through Monday, and could
inhibit some low cloud coverage tonight, resulting in intermittent
and patchy cigs. Moderate to high confidence in areas of vis 1-3 sm
along western fringe of valleys, and on elevated coastal terrain
including kcrq, between 10-16z Monday. Elsewhere, vis 3-5 sm during
early morning hours. Low CIGS should dissipate near 16 16z withVFR
conditions prevailing thereafter, however variable sct-bkn clouds
with bases near 10,000 ft and tops to 20,000 ft can be expected
throughout the day.
Valleys mountains deserts... Sct high clouds AOA 15,000 ft msl
Small patches of low clouds may reduce visibility to near 1 mile
tonight, however confidence is low. Visibility is not expected to
drop below 1 mile.
It is another hot, dry day inland with minimum rh values of 15% or
less far inland valleys mts. An afternoon sea breeze will bring
gusts of 15 to 20 mph at times through early evening. This will
result in elevated fire weather conditions. Further increases in rh
will occur on Monday as onshore flow strengthens and an upper-level
trough moves across the state. Some instability aloft may produce
sprinkles with gusty and erratic winds at times. At this point the
dry lightning threat looks to be 15% or less on Monday.
Winds have been increasing over southwest san bernardino county
today, with peak gusts around 35 mph. These winds will become more
widespread and turn westerly Monday and Monday night with gusts of
30 to locally 50 mph on the desert slopes and near the passes. These
winds will be accompanied by higher rh initially, but will fall to
around 15% or lower by Tuesday morning in some areas. Critical fire
weather conditions may develop for a few hours on the ridges and
desert slopes before the winds drop off midday Tuesday.
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
