Sally Moving Slowly Toward Gulf Coast


Smokey skies continue over Tucson this morning - this makes one full week with the smoke from California continuing overhead here. Visible satellite image (below) from 2115 UTC (2:15 pm MST) yesterday afternoon shows the smoke across all but the southeast U.S. Model trajectories indicate that the smoke plumes have reached east across the Atlantic to the UK and Europe.

Forecasts for total precipitation through 5:00 pm next Monday afternoon (the 21st) hold little hope for  the Southwest - above is from the 00 UTC WRF=GFS and below is from the 00 UTC GFS run. The GEFS plumes are also flat-lined.

The Atlantic continues very active, with five named tropical storms this morning (above shows IR image from 15 UTC this morning,and below shows morning shows the storms as per NHC). Paulette is currently the only hurricane, but Sally is forecast to to make landfall near Gulfport, Mississippi, tonight as a Category 1 hurricane.
