Brief Summary Of Weather Event


Once again, the Atmo high-resolution version of the WRF model provided quite accurate forecasts for the event of yesterday afternoon and last night (see below). As the model predicted, rainfall was limited to the Catalina mountains in the Tucson area. ALERT map above shows the Catalina sites that measured light rainfall during past 24-hours - 10 sites with all amounts under a quarter of an inch. Gauges across the metro area recorded no rainfall, nor did any of the rest of the gauges in the ALERT network - so, as the model sadly indicated, zero POPs over most of region. Here at the house we had the briefest and slightest spit of rain just before 6:30 pm - just enough to add a brief smell of rain to the air. off to the northeast, the RAWS station on Mt. Graham had light rain, as did three RAWS sites off to the northeast of Mt. Graham. So, mostly stymied again across southeast Arizona!
