First Workweek of April 2023

Postby sd » Tue Apr 04, 2023 4:08 pm

Tuesday afternoon outlook for the remaining workweek

Yesterday (Monday) the north wind was too much for PGs
Today (Tuesday) the north wind backed down considerably but still had some early gusto that blocked with a robust lapse rate on the south side at the lower altitudes. It was likely launchable from EJ by early afternoon?

Tomorrow (Wednesday) high pressure continues to build as the wind clocks around to come off the high desert and drain offshore (Santa Ana). The lapse rate relaxes but is still good. Wednesday looks like it offers the best altitude, more so toward the east.
In SB, expect early NE up higher as the SW builds and pulls in underneath. By early afternoon the west should push through at our soaring altitudes and build from the NW up higher on the west end of the course. Potential for significant thickening high clouds as the afternoon ages.
More east wind to the east. Fillmore has a good lapse rate but too much east wind to launch early from Oat. Logan might be able to get off from San Cayetano? The east wind relaxes toward Fillmore later in the day and the altitude looks good, (6 to7K). You might be able bridge across the river toward Simi as the west pulls in under the east?
The Nuthouse in Ojai likely offers the longest course potential both Wednesday and Thursday.
Ojai looks good with increasing altitude through the day. Likely a good day to start at the Nuthouse and tag a westbound point before returning toward Fillmore?

You can likely go OTB at Divide for better altitude, but only to about 8 or 9K on Wednesday and Thursday, so it might not be worth the risk of hiking with all the backcountry roads closed?

Thursday continues to warm aloft but the lapse rate is still ok. The Santa Ana east wind continues and the west draws in less. Ojai looks good again with increasing altitude through the day but maybe not as good as Wednesday as the atmosphere warms.

Friday is a switch day as the offshore gradients trend onshore. The lapse rate is weaker and it won’t likely work very good down low. The lapse is much better above 4K. If you are able to claw down range to Casitas Pass the altitude looks better OTB toward Monte Arido and 3-Sisters, maybe 10K.

Still some potential for afternoon high clouds, but less than Wednesday.
