Gusty East Winds Bring Milder Morning Temperatures

I was busy with other things yesterday and did not pay enough attention to the weather, not even look at the WRF forecasts. So, a surprise this morning when I went out for the newspaper - gusty east winds, wind chimes making noise, and much milder temperatures. The above plot from MesoWest shows temperatures, winds, and gusts (red) at 5:45 am MST this morning. Quite a change from yesterday's near to below freezing temperatures. There are quite a few stations reporting gusts of 30 to 40 mph - Mt. Hopkins RAWS site with gusts to 47 mph, above, has hit 56 mph during past couple of hours. The 12 UTC WRF-NAM had forecast the winds fairly accurately - forecast below for 10-m winds at 8:00 am this morning. The model-based temperature forecasts had a low of only 60 F for TUS this morning - a bit overdone, but very good on the 24-hour trend at the airport. Can't take your eye off the ball in the weather world!
