Tonight

With the loss of diurnal mixing tonight, the wind gusts will gradually decline this evening and overnight. Even with that the sustained winds will remain in the 10 to 20 mph range. The combination of warm air advection and the low-levels remaining well-mixed, low temperatures will be warmer tonight. They will range from the lower 30s to lower 40s.

Sunday

As the day warms on Sunday morning, southerly wind gusts will increase into the 25 to 35 mph range. In addition, this will mix down warmer air from aloft to the surface. With the NBM running on the cool side, used a mix of 1/3rd NBM and 2/3rds NBM 90th percentile to raise these temperatures up anywhere from 2 to 4F.
