Middle May

Visible satellite image of the Southwest at 7:06 am MST this morning (above) indicates only isolated cloudiness over northern Arizona. Image below shows the devastation done to the grass on the Mall because of the mobile vaccination center that has been located there.

Image at bottom shows Tropical Cyclone Tauktae, which is moving northward, just off the west coast of India. 

At 500 mb this morning there is a large, closed low centered over the Great Basin, as well as an east-west trough extending from the low to southern Wisconsin. The precipitable water graphic (below valid at 6:00 am) shows how very dry the western US is, which explains the limited cloudiness shown in the satellite image above.

Main impact of the system moving by to our north will be gusty winds during the afternoons this week - as per 06 UTC plumes for steady wind speeds shown above. The 06 UTC WRF forecast (below valid at 2:30 pm Tuesday) indicates that tomorrow will have the strongest winds during the next several days.
