The Wyoming upper-air soundings site shows the following values for the total precipitable water-vapor working south and east from Flagstaff for the 0h UT balloon soundings this evening: Flagstaff 2.6mm (pretty dry) Tucson 11.5mm El Paso 21.4mm Midland/Odessa 31.3mm (north of TSP) Del Rio TX 36.0mm Key West 45.5mm San Juan 48.8mm ...so west Texas is about 3/4 the way to "tropical" tonight. Could be worse, even from there: the midnight sounding in Douala, Cameroon showed surface temperature of 26C with total water-vapor of 67mm. (When it gets to about 17-18mm in summer in Flagstaff, it means it's raining.)
