SE's often amp right at 1 pm and stay strong until about 5. I think the heat helps it ramp somehow.
I look for a strong band of storms to our North on days that SE winds are predicted. If the bands are there when I wake up, I get pretty amped, 'cuz we are nearly always good to go (only skunked one day last year of about 15 of these), usually with some pretty strong stuff, like 15 to 25.
Also, I have noticed if it is good, it will feel like dry heat in town (hair dryer effect). So, if you are in town and feel like the Wind Gods are blow drying you hair at lunch break... well, don't go back to work (lmao).
Not very scientific, just observations.
