...UPDATED AVIATION DISCUSSION...
At 11 AM, the pressure gradient from San Diego to
Tonopah, NV was running 5.6 mb offshore. Winds had come down from
their peak with only place with wind gusts over 30 mph was
directly below the Cajon Pass. Earlier today gusts to 45 mph were
observed near the Cajon Pass. Weak offshore flow will continue
into Sunday, becoming weakly onshore by Monday. Given the
unsettled weather quickly turning to offshore flow, marine layer
low clouds and fog will be absent from the coast this weekend.
It`s possible low clouds could return to some locations Monday
morning, with higher confidence for low clouds returning by
Tuesday morning.
High temperatures on Sunday are expected to be 3 to 5 degrees warmer
than today with another degree or two of warming expected on Monday.
By Monday, high temperatures in coastal areas will be 5 to 10
degrees above average, with temperatures closer to average further
inland. Temperatures will begin to trend below average by the end of
the week.
Global ensembles are indicating the potential for unsettled weather
for the end of next week. There remains a lot of spread in solutions
and uncertainty in the details. Rain chances are in the forecast as
early as Friday. In addition to precipitation, cooler, cloudier, and
windier conditions may develop. Please be prepared for more wet
weather impacts, especially as you start to make those Halloween
weekend plans.
