March 2018 - In and Out Like A Lamb

A 500 mb trough will linger over the Southwest for next 96-hours or so. Above is from 00 UTC last evening and shows the GEFS mean 500 mb heights for 48-hours (26 March 5 pm MST) and below is same but for 96-hours (28 March 5 pm).

Second below is from 06 UTC GEFS forecasts last night - shown are the plumes for PW at TUS. During a windy afternoon today PW plummets to very low values and and basically is forecast to stay low for rest of the month.

Bottom shows 00 UTC WRF-GFS forecast for precipitation (on 5.4 km grid) through  5 pm on March 31st - a very dismal forecast except for a few mountain peaks over northeastern Arizona. 

While T. S. Eliot said that April is the cruelest month, that usually doesn't apply here in Arizona. So, we'll be moving ahead toward our first 100 F day (note that temperature at TUS reached 91 F on Thursday afternoon).
