Wind And Dust Cycle Continues

Dust still hanging in the air this morning - early morning RH has only crept up to a very dry 13 percent. The 06 UTC GEFS plumes for wind (below) key on another spate of high winds for Thursday. The 06 UTC WRF-GFS forecast of 10-m winds valid at 4:00 pm MST on Thursday (second below) indicates the same.

Down at bottom is commentary on the ridiculous state of NWS short-term forecast graphics - this will be first of several posts about the problems with grid forecasts and meteorological absurdities.

If one goes to the NWS TUS web page this morning he/she finds both of these graphics about a Red Flag Warning for today - obviously a very short-term and important product. The real warning area is above; whereas the point-interactive graphic (below) that brings up the supposedly "high resolution" grid point forecasts shows a much larger area. What I find inexcusable is that a click, say on TUS, indicates a Red Flag Warning in effect - but this is not so for Tucson. Such inconsistencies at very short-terms should be totally inexcusable - but apparently management in NWS at Regional and National levels does not care.
