Cold And Damp Morning

The WRF-GFS forecast discussed on Thursday morning was, yet again, quite accurate. The front passed through the metro area of Tucson a bit before 6 am this morning (Saturday, April 14th). Showers began here at the house right around 6 am and have amounted to about 0.15". As the webcams on Kitt Peak and Mt. Lemmon (above and below) show, there was a light accumulation of snow on both mountains. At 5:30 am only 20 of 93 sites in the Pima County ALERT network had measured rainfall - number with snow fall unknown. By 9:30 am only 3 sites in the far south part of network had not had precipitation. Amounts were generally around 1 to 2 tenths of an inch in the lower elevation metro areas. Higher amounts were measured both on Redington Pass and along the northwestern foothills of the Catalinas - 9 sites had over half an inch with maximum amount being 0.91". There are still showers around, so final amounts could increase a bit. Another mid-month, fast-hitting weather event - will this be April's only event? Long range forecasts show little promise at this time, but there's still more than 2 weeks left in the month.
