The jet stream continues to remain stationary, carving out a cyclonic northwest flow of air over the entire West.
This will continue periods of wind, cooler than normal temps and even a slight chance of a shower or thunderstorm on Wednesday.
Monday 85-89 | 58-63 | afternoon & evening winds
Tuesday 80-86 | 55-60 | afternoon & evening winds
Wednesday 79-85 | 55-60 | SLIGHT 10% CHANCE OF SHOWER & THUNDERSTORMS
Thursday 85-90 | 59-65 | afternoon & evening winds
Friday, Saturday, Sunday 88-93 | 59-65 | afternoon & evening winds
Low pressure systems moving south along the Pacific coast will continue to influence our weather by bringing cool air originating from the west coast of Canada down south toward our area.
This will bring periods of gusty winds throughout the next week, comfortable and cooler than normal temperatures (normal is 97 this time of year!), and even a slight chance of showers or thunderstorms on Wednesday as one of the stronger low pressure systems creates a slightly unstable airmass as it moves through our area from the north. This same system may even bring 3-6 inches of snow to the higher peaks of the High Sierras this week. Memorial Day vacations to the Sierras should keep an eye out on forecasts! Temps could be cold and high elevations could have snow flurries this week.
Winds here in the Coachella Valey will vary each day... some days will gust to 25-30 mph each afternoon and evening, mainly on the north end of the Coachella Valley cities, as well as along the I-10 corridor from Whitewater to Indio, as well as in the high deserts from Morongo to 29 Palms. Other days (most likely Tuesday), may see stronger gusts to 40+, and winds may gust from the south or southwest, as they have at times the past several weeks, influencing southern area weather such as Indian Canyons, Araby and the Cathedral City Cove, in addition to the usual suspects closer to I-10 that will be subject to northwest onslaughts.

This is the windiest time of year. April, May and June, on average, have the most regular occurrences of high winds. This is due to the increasing heat over the deserts combining with the cooler marine air over the coastal areas to our west, creating what is called a "thermal" or temperature gradient. The relatively warmer air rising over the deserts each afternoon attracts the cool air from the Pacific to replace it, creating a nearly constant pattern of gusty winds every afternoon and early nighttime. The natural topography of our mountain ranges creates funnels through the nearby mountain passes, allowing erratic and localized wind conditions that hit certain areas depending upon wind direction, inversions, temperature differential and other scenarios that influence whether one day will be windier than the next. This year has been particularly windy due to frequent low pressure systems just to our north, accentuating the normal spring time weather patterns with extra upper level energy as well.
For those following the demise of the warm water phenomenon known as El Nino, water temperatures this week continue to drop in the Equatorial Pacific. Graph below courtesy of Unisys.
As long as you don't mind some wind, enjoy the stunning desert weather this week! Slight chance of some lenticular clouds on Tuesday or Wednesday could make for some great photography! Get out and enjoy our beautiful desert this week before temps make their eventual turn into the 100's at some point again in the weeks to come!
