northerly winds during the overnight and early morning hours with
a brief switchover out of the east during the mid to late morning
hours prior to the westerly shift in the afternoon. Sustained wind
speeds throughout the entire period are expected to remain under
15 mph, however, occasional afternoon and early evening gusts
upwards of 20-25 mph will be common each day. MinRH values will
hover near 10% while overnight recoveries will be poor as MaxRHs
