Heat Wave Expected to Peak Today. Equatorial Pacific in Transition.

Temperatures today at Los Angeles Pierce College in Woodland Hills appear to be running about a degree hotter than yesterday, when a new record high for the date of 109°F was recorded at the campus weather station.

A BUFKIT analysis of 12z data for Van Nuys shows temps peaking today at about 107°F, followed by a slow cooling trend into next week, with high temps dropping down into the high eighties. In this graph of temperatures, the red line is the 2-meter temperature and the blue line is the surface "skin" temperature.

Equatorial Pacific SSTs continue the transition to neutral conditions. This TAO section plot of 5-day Depth Average Temperature clearly shows the change in state with a marked increase in sub-surface temperatures, particularly in the far eastern and western equatorial Pacific.
