Brief WRF Update For Saturday, May 24th


The runs of the WRF forecast model today at Atmo have reduced the coverage of showers over southern Arizona for today and tomorrow. Graphic above shows total rainfall predicted by the early run of the WRF-NAM - the period runs through midnight Sunday. Note that only forecast for showers in Tucson metro area is for developments that move from the Catalinas east-southeastward. Currently there are showers and buildups on the Catalinas and the Rincons. The new, 12 UTC runs this morning have almost eliminated any forecast of showers over the entire southern half of Arizona, with only some very light showers moving off the mountains of eastern Pima County today.

Meanwhile, the Slide wildfire continues to burn between Sedona and Flagstaff - map of fire from last evening below. The fire has burned more than 10,000 acres as of morning today, and forced some evacuations. It is only 5 percent contained. While winds will be lighter than last several days, they will be blowing from westerly directions rather than from the south-southeast. The fire is in very rugged terrain and difficult for firefighters to combat.
