We continue to use LIS data to increase our awareness of potential flood prone areas, as well as potential problems with convective dust storms. An example below of interaction with the Phoenix office on 12Planet this morning where we discuss possible dust problems and inserting blowing dust in weather grids:
Below are this morning’s volumetric and relative soil moistures. It highlights 2 concerns for us today. The first is the area of heavy rain we saw 36 hours ago in the Tucson area and surrounding mountains is still very much reflected in soil moistures. This will be one of the main areas of concern for potential flash flooding today. The second concern is dust, with dry antecedent soil conditions a concern in favored blowing dust areas Pinal, Maricopa and central Pima counties.
Finally, below is a look at the University of Arizona WRF-NAM 10m wind showing some very interesting convective outflows. The first generated around the Tucson area this afternoon from the strong potential of our atmospheric profile today, and the second southwest of Tucson after 00z from the influence of an impulse embedded in the moist southwesterly flow early this evening:
So that will be what we’re watching closely for today. After a review of the 12z data, the day shift will coordinate with the Phoenix office on the possible issuance of an extended long fuse Blowing Dust Advisory. We will also be issuing a partner coordination e-mail to local and state officials on this potential, and a heightened awareness weather story for the web site and social media.
