Windy Morning - Friday March 9th


It's very windy at sunrise here at the house with east winds of 30 to 40 mph. The plot above from Atmo rooftop anemometer (not sure why it's broken up a bit) indicates wind gusts over 50 mph. The Atmo early WRF-GFS (below) for 10 am this morning forecasts east winds of 25 to 30 mph - with gusts likely. Winds are being produced by strong low-level pressure gradient as high pressure sinks southward over and east of the Rockies.


The 500 mb closed low is wobbling around above southwestern New Mexico and some model solutions bring it a bit toward the west today. The early WRF-GFS forecasts some precipitation to the northeast of Tucson and over New Mexico through noon tomorrow (see below).


The Tucson Festival of Books will occur Saturday and Sunday on campus at the University of Arizona.  The event tents are all up on the Mall (see image below) and they could be vulnerable to the strong winds this morning!
