SYNOPSIS

10/936 PM.

Night through morning low clouds and fog will continue for the next several days over the coast and valleys with slow, if any, clearing at the coast. Areas away from the coast will remain much warmer than normal through the week.

LONG TERM (SAT-TUE)

10/143 PM.

High pressure will be strengthening again this weekend into early next week that will push high temperatures back up to the mid to hi 90s for the valleys with at least a 30% chance of highs up to around 102-104 in the warmest valleys, peaking on Sunday. There remains some uncertainty with how far west the bubble of high pressure will expand but confidence is high that triple digit temperatures will develop in the Antelope Valley and near 100 or slightly higher in the warmer coastal valleys.

The ridge of high pressure is expected to weaken early next week and be replaced by an upper level trough that will bring temperatures back to normal levels. In addition, a deepening marine layer will push marine layer stratus farther inland with slower clearing.

AVIATION

11/0727Z.

At 0655Z at KLAX, the marine layer was around 700 feet deep. The top of the inversion was at 4600 ft with a temperature of 25 C.

High confidence in VFR TAFs for KPMD and KWJF.

Moderate to low confidence in remaining TAFs. There is a 40% chance VFR conds prevail through the period at KPRB and timing of flight cat changes may be off +/- 2 hours. For coastal TAFs, transition to VFR may be off +/- 90 minutes. However, there is a chance for no clearing at KSBA (30%), KOXR (40%), KCMA (20%), KLAX (30%), and KSMO (30%). Moderate to high confidence in minimum flight cats, but timing of flight cat changes may be off +/- 2 hours.

KLAX...Low to moderate confidence in TAF. Flight cat changes may be off +/- 2 hours. Lower confidence in timing of LIFR cigs. There is a 30% chance of no VFR transition in the afternoon. No significant east wind component is expected.

KBUR...Low to moderate confidence in TAF. Timing of flight category changes could be off +/- 2 hours. There is a 30% chance that CIG/VSBY restrictions do not develop tonight.

MARINE

11/1218 AM.

For the Outer Waters, high confidence in current forecast. Small Craft Advisory (SCA) level winds will continue through Saturday (with some temporary lulls during the overnight to early morning hours). Also, there may be a few localized gusts that approach GALE force Wednesday evening around Point Conception (20% chance). Seas will approach SCA levels as early as Thursday, possibly reaching 10 feet early next week.

For the Inner Waters north of Point Sal, moderate to high confidence in current forecast. For Wednesday through Saturday, there is a 70-90% chance of SCA level winds, mainly in the afternoon and evening hours. Seas will approach SCA levels Friday and again early next week.

For the Inner Waters south of Point Conception, moderate confidence in current forecast. There is 70% chance of SCA level winds across western portions of the Santa Barbara Channel tomorrow afternoon/eve, with a 30-50% chance each day through Saturday. Elsewhere, high confidence in wind and seas remaining below SCA criteria.

LOX WATCHES/WARNINGS/ADVISORIES
