Smoke Aloft Over Tucson

Winds aloft this morning have an easterly component from 700 to 300 mb. The flow is advecting the smoke plume from the Gila Wilderness fires across southeastern Arizona. Above is 300 mb, 12 UTC analysis (from NCAR) showing the northeast flow, east of an upper anticyclone that's currently centered over California. Visible satellite image at sunrise today (below) shows the large smoke plume from southeast Arizona eastward across the Texas Big Bend country. The NWS forecasts a high of 108F for the airport tomorrow, so no relief in sight from the heat and drought.
