View of Catalinas at 7:00 am MST this morning shows clear, but hazy skies.
Plumes for the 06 UTC EFS runs for temperature (above) indicate a very hot week coming for us. The NWS has issued an Excessive Heat Watch (below) because of the expected daily highs well above 100 F. Note that high temperatures at airport for past 7 days have ranged from 101 to 104 F - hot turns hotter.
In the longer term, 500 mb forecasts from the GFS 06 UTC run show a complex anticyclone pattern at 7 days (above) with centers over east Texas, California/Nevada border, and well west of Baja. By 14 days (below) the high has consolidated and is centered to our southeast, as the first week of July ends. The precipitation prospects remain low, with rainfall through 14 days extending northward just to the southeastern Arizona border (second below, also from 06 UTC GFS run). So, if model forecasts are correct, it will be well into July before our onset of summer storms and rain.
