Synopsis
A frontal system will approach today into tonight with a wave of low
pressure riding along it to our north Thursday morning. The low will
drag a cold front across the region Thursday afternoon. High pressure
will then build into the region Thursday night and remain
nearby through Saturday. A cold front will approach and move
across the area on Sunday. Another cold front and low pressure
system will move across the area early next week.

Near term until 6 pm this evening
Spotty radar returns have developed over western northern zones,
however so far have yet to see any evidence of precipitation
being reported at the various ASOS they have passed over.

However, cannot have 100% confidence that no precipitation is
reaching the ground, so have increased pops to slight chance
early this afternoon and issued an sps for patchy freezing rain
for orange county where there are areas with temperatures still
at or below freezing. Given the t-td spread, could also see some
spotty reports of sleet with these returns.

Highs this afternoon should range from the mid-upper 30s across
the NW zones to the lower 40s for coastal zones.

Short term 6 pm this evening through 6 pm Thursday
Light rain spreads across the area tonight, and at the same time,
temperatures continue to rise on a s-sw wind flow. There's still
some concern that parts of the far NW zones could have surface temps
supportive of freezing rain at the time when rain becomes likely, so
will need to keep close watch on this potential.

Rain becomes more moderate early Thursday morning, and could be
heavy at times by mid-morning with strong isentropic lift and an
impressive llj. Approaching shortwave energy should enhance forced
ascent and also create weak destabilization aloft, increasing the
chances of heavier downpours. After collaboration with the
surrounding office, have issued a flash flood watch for Thursday.

Smaller stream and urban poor drainage flooding would be the main
threat. Timing of the greatest flood threat looks like morning to
midday. A cold front passes through during the afternoon with rain
probably coming to an end not too long after the passage, however a
strong upper jet streak shifts in with enhanced lift, continuing at
least chances of additional pcpn. Could be cold enough for a
mixlight rain has developed over far western zones of rain and
snow for far NW areas late-day.

It should also become breezy, especially near the coast. Strong
winds with the LLJ will be not too far above the surface, however
with such a strong inversion, thinking is that none of the area
would likely see advisory-level gusts.

Long term Thursday night through Wednesday
High pressure builds into the area behind a departing cold front
Thursday night and remain in place through Saturday. This will
result in dry and cold conditions. Highs on Friday will climb into
the lower and middle 30s, while highs will struggle to get out of the
20s on Saturday.

The high moves offshore Saturday night, allowing a an upper level
shortwave and associated surface cold front to move across the area
on Sunday. This could result in a few snow showers, will keep pops
at chance or slight chance for now. No accumulations at this time are
expected with any of the snow showers.

A stronger shortwave and associated frontal system will move across
the area early next week, bringing yet another chance of
precipitation to the region. There are differences with the exact
track and placement with this next system, so details remain
somewhat sketchy.

Temperatures on Sunday through Tuesday will climb 30s and lower
40s.

Light rain has developed over far western zones

Aviation 18z Wednesday through Monday
A frontal system will approach today into tonight with a wave of low
pressure riding along it to our north Thursday morning.

Ceilings generally 025-035 should persist into the evening,
with the lowest ceilings expected across kswf, khpn, kewr and
kteb. MVFR ceilings will gradually move into the remainder of
the terminals this evening. Thereafter, ifr or lower develops
later this evening in steadier light rain, becoming increasingly
prevailing after midnight as rain intensity increases. At
least initially, a wintry mix is possible at kswf through around
21z.

S SW winds 10 kt will increase to 10-15 kt and with occasional gusts
to near 20 kt possible for south coastal terminals. S winds 10
to 15 kt for coastal terminals tonight, increasing to 15 to 25
kt towards the Thursday morning push. Llws from SW winds of
50-60kt@2 kft developing for coastal terminals by evening,
strengthening to near 60-70kt, especially from kjfk eastward.

Winds then shift to wnw and remain strong following the frontal
passage Thursday, from west to east between 17-20z. Conditions
will gradually improve to MVFR toVFR following the passage.
