A short-wave trough will move into the Northwest this afternoon with a cold front moving through the Northwest and into the northern Rockies and northern Great Basin. Breezy and dry west winds are expected across much of the Arizona into central New Mexico with isolated mixed wet and dry thunderstorms along the dry line across the eastern plains for New Mexico. Very warm and dry north winds are forecast for the Sacramento Valley this afternoon continuing into tonight with poor overnight relative humidity recovery. Low to very low afternoon relative humidity is forecast across the Northeast and the southern Great Basin as well, but winds will be light.

Scattered showers and thunderstorms will develop across the Northwest into the northern Rockies and northern Plains as well. A cooling trend is forecast for much of the Alaska Interior today with higher relative humidity but conditions will remain dry for most of the state except for light showers over portions of south-central Alaska.
