SYNOPSIS

15/242 AM.

Warm but below normal temperatures will continue through Thursday, with expanding coastal morning low clouds. Temperatures are likely to increase towards the end of the week.

LONG TERM (FRI-MON)

15/242 AM.

Not much going on in the xtnd very weak ridging moves into the area Friday and continues into Saturday hgts may approach 588 dam. Mdt onshore flow will continue to the east. There will be weak offshore flow in the morning from the north but it will turn to weak onshore flow in the afternoon. The morning offshore push should reduce (but not eliminate) the morning low cloud coverage. Look for 2 to 4 degrees of warming each day. This will lead to max temps in the 70s and lower 80s across the csts and 80s in the vlys on Saturday. Despite the warming these max temps are still 2 to 4 degrees blo normal.

A weak, high hgt and dry upper low will move into the area Sunday and Monday. Its effects will be minimal, just an increase in marine layer clouds and a few degrees of cooling.

AVIATION

15/0942Z.

At 0832Z at KLAX, the marine layer was 2600 feet deep. The top of the inversion was at 4400 feet with a temperature of 19 C.

High confidence in TAFs for KPRB, KPMD & KWJF

Moderate confidence in the remainder of the TAFs where cigs may rise faster than fcst and VFR conds may arrive up to 90 minutes later than fcst. There is a 30 percent chc of -DZ.

KLAX...Moderate confidence in TAF. Cigs may rise faster than fcst. VFR conds may arrive as late as 2130Z. Good confidence that there will be a greater than 8kt east wind component best chances 12Z-16Z.

KBUR...Moderate confidence in TAF. Cigs may rise faster than fcst. VFR conds may arrive as late as 2100Z.

MARINE

15/232 AM.

High confidence that Small Craft Advisory (SCA) winds and seas will continue through through this morning around 9 AM over the Outer Waters. Seas over the outer waters are currently between 7 to 9 feet at short periods, 6 to 8 seconds, but will begin to subside as the winds ease. High confidence in relatively light winds with no SCA conditions over the area through Thursday morning, with a return of normal Outer Waters (and potentially Santa Barbara Channel) northwest SCA winds for Thursday night into the weekend. These winds will generate a building short period swell over all waters.

Stronger than usual southeast winds are likely south of Point Conception through mid to late morning today. Winds will be strongest through the San Pedro Channel and northward into the eastern Santa Barbara Channel. While SCAs are not expected, local gusts 15-20 knots are possible between the islands. Locally choppy seas could make conditions hazardous for smaller craft.
