Sunny But Cooler This Week

03 October 2016   Dr. Curtis James
Temperatures are headed into cooler territory this week. 

The figure above indicates the forecasted high in orange (with error bar denoting the range of ensemble forecast members), average high for this time of year in orange (dashed line), forecasted low in blue (with error bar), average low this time of year in blue (dashed line), and forecasted wind speed in purple. Note that the wind speed forecast is sustained wind (not gusts), and it is based on only one model (not an ensemble).

Weather Discussion:

Two back-to-back troughs moving through the Great Basin this week will keep the flow aloft west or northwesterly across Arizona. This flow pattern will bring us breezes and a pronounced drying trend, which will lead to low temperatures down into the lower 40s or upper 30s tonight. Temperatures will be slightly below normal in general for most of the week, but will warm up gradually this coming weekend. No precipitation expected through at least Saturday or Sunday.
