More Wind Today

Some high clouds this morning, but they are very far off to the northeast. Down at bottom is a current view of Dangling Rope Marina on Lake Powell, in southern Utah just a bit northeast of Page, Arizona. Note how very low the water level is in Lake Powell.

At 500 mb this morning (above) there is a very large, closed low over the western third of the country. There appear to be two circulation centers within this low: one over far southwestern Idaho and the other along the California coast northwest of San Diego.

As the low moves eastward, we'll have another day with strong winds and critical fire danger, as per above from the SPC and below from the TUS Forecast Office. Winds yesterday produced gusts as high as 38 mph at the airport.

Graphics here are from the 12 UTC WRF-RR forecasts at Atmo. Forecast of steady wind speeds above is valid at 2:30 pm. Note that a very large portion of both Arizona and New Mexico will be dealing with the gusty winds. 

Forecast below, is for total rainfall from now through the end of the month (00 UTC on June 1st) - Arizona remains DRY!
