We do a seven day forecast at KMIR. Yesterday I mentioned Day Eight. It got a shout out (as Day Seven) again tonight. That’s because there’s rain forecast next Thursday.
The actual value to rain in the Coachella Valley (Palm Springs area) is debatable. We average less than six inches per year. The majority of our water comes from an underground aquifer. It would be long gone if not supplemented by water piped in from Parker Dam on the Colorado River. Rainfall seeping down is a small piece of our specific puzzle.
Nature doesn’t provide nearly enough to support our population and the hundreds of thousands of tourists who arrive every week during the season.
Whether rainwater helps or not, people in the valley value it. Mentioning rain here is like mentioning snow in New England. It grabs your attention.
If you break down next Thursday’s rain forecast over Palm Springs, it comes to .06″. Tiny. Hardly noticeable.
A forecast for that small amount of liquid a week away is chancy at best, especially when you throw in:
EARLY NEXT WEEK A GULF OF ALASKA LOW WILL DEEPEN OVER THE PACIFIC NORTHWEST AND SEND A SERIES OF SHORTWAVES DOWN THE WEST COAST AND ACROSS SOUTHERN CALIFORNIA WEDNESDAY THROUGH FRIDAY. THIS UNUSUAL APRIL PATTERN WOULD BRING A DECENT CHANCE AT PRECIPITATION IF WERE TO UNFOLD. BUT THIS PATTERN HAS BEEN FORECAST SEVERAL TIMES THIS WINTER AND HAS EITHER 1) SUBSTANTIALLY WEAKENED OVER TIME OR 2) FAILED TO MATERIALIZE AT ALL. FOR NOW WILL HOLD ON TO A SLIGHT CHANCE FOR PRECIPITATION FOR THE MIDDLE AND LATER STAGES OF NEXT WEEK. – Area Forecast Discussion NWS San Diego
Wish us luck. It will get my attention on every newscast.
