FORECAST DISCUSSION

High pressure is setting up a position it will take for the next few days sitting just off the coast. This has been driving the Sundowners on the southcoast. People have asked what a sundowner is. Let me keep it as simple as I can. It is high pressure north of the Santa Ynez range and lower pressure south. It causes a N-NW Wind which downslopes over the local topography, typically beginning the greatet impact after sunset and through the overnight hours earning its name. The sinking and compressing of the downslope low warms up the air and dries it out That is why its forecasting is so critical for firefighters.

This is possible for the next several days since high pressure is parked where it is. For the rest of the region it’ll mean a N flow early each day with NW winds late. This will produce warmer coastal and interior valley temps. Slight cooling should happen this weekend with more NW component and return of occasionally organized marine intrusion.

FIRE THOUGHTS

Watching the fire near Santa Barbara that broke out Tuesday you have to at least draw some comparisons between it and the Tea Fire from November.

Yes, both did have sundowner winds however the severity of this event is much less. The Tea Fire had winds to 70mph after it broke out, the top winds I have seen thus far are more like 40 and they didn’t last nearly as long at the peak (at least not yet).

The Tea fire was at the end of a dry summer, the Jesusita Fire is coming at the end of a rain season. Granted it was a very dry one, with less than 10 inches of rain in the SB Area (about 58% of normal).

Earlier this year the SB Fire officials did away with the designation of ‘on’ and ‘off’ fire seasons; you can certainly see the wisdom in that now as this would typically be considered ‘off season’.

We will see sundowner potential over the next couple of days so fire containment is key. As far as weather conditions go they are certainly not ideal, but again we have seen worse…a lot worse.

Another warm day on tap especially for Santa Barbara South Coast. The ridge of high pressure continues to build into the area and winds will keep the South Coast much warmer than San Luis Obispo county. Overall, still a warm day.

high

Later this evening, advisory level winds will return for the Santa Ynez range. So expect some windy weather by late this evening. Some areas will see mid to high level clouds roll in but nothing too major.

Expected daytime highs today:

Santa Barbara temp: 86

San Luis Obispo: 72 (it could be warmer)

Paso Robles: 80

Santa Ynez: 76

Santa Maria: 68

Right now we have patchy low clouds right along the San Luis Obispo coast but it’s been clear in Santa Barbara’s South Coast. This is the

A strong upper level trough is parked over the region with 50-80KT winds at jet stream level. At the surface that is translated into afternoon winds 20-30mph. The stronger afternoon winds have mixed out much of the marine cloud cover of the last several days. Here is a look at the rawinsonde plot showing the strong jet stream:

The real question is where do we go from here?
