Cooler, Chance of Showers Thurs-Sat Morning

25 October 2015   Dr. Curtis James

 Will it rain 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:

    A disturbance moving through Utah tonight and tomorrow will bring some clouds, but precipitation is unlikely for Monday. Expect mostly clear skies and mild weather on Tuesday, with increasing clouds  and breezes Wednesday – Thursday as a deeper trough digs down the West Coast and into Arizona. Temperatures will cool on Thursday and there will be a slight chance of rain showers.

     What happens on Friday thereafter is still quite uncertain, but some models are indicating an even larger and colder low pressure system digging down into Arizona on Friday and moving east of the state by Saturday afternoon (Halloween). This could bring even cooler temperatures Friday – Saturday. The chance of showers will diminish on Saturday, but be prepared to bundle up for your Halloween festivities.

      More details later this week...
