Marine Weather and Tide Forecast for Coachella, CA

KEY MESSAGES

- Breezy to windy conditions will become common this weekend, especially by Sunday, as a low pressure system slides eastward off the Pacific early next week.

- Temperatures will warm into the middle nineties across the lower deserts this weekend, followed by a cooldown back into the eighties early next week.

SHORT TERM /TODAY THROUGH SUNDAY/
On mid-level WV imagery the core of the closed low, that passed to the region's SE throughout this evening, is now centered over the international border between SE Arizona and SW New Mexico.
Meanwhile, ridging can be seen building over the west coast and will move further inland starting today but temperatures today will continue to be mostly in the lower to mid 90s across the lower deserts. Over the weekend temperatures will warm further in response to H5 heights increasing to between 576-580 dam on Saturday and Sunday. Afternoon highs in the lower deserts ill be in the mid to upper 90s, or about 5-7 degrees above normal for this time of year.

By Sunday another closed low is projected to form off the coast of northern California. This system is not expected to be over the Desert SW until early next week, however ahead of the system, as early as Sunday afternoon, widespread breezy to locally windy conditions in SW Arizona and SE California will develop. During this time gusts between 25-35 MPH will be common. This may result in locally elevated fire weather concerns, particularly Sunday afternoon into the early evening for portions of the Lower Colorado River Valley and La Paz county.

LONG TERM /MONDAY THROUGH THURSDAY/
By early next week the aforementioned closed low will begin to move inland and migrate southeastwards down the state of California before moving into the Desert SW. This will help kick off the work week with temperatures cooling to below normal with afternoon highs in the low to mid 80s on both Monday and Tuesday along with breezy to locally windy conditions continuing. By mid week, confidence in the forecast decreases considerably with cluster analysis showing differences in when this closed low will exit the region or if it simply weakens as positive height anomalies build from the Pacific Northwest. Even with this next closed low system approaching, models currently point towards conditions remaining dry and a warming trend by mid to late next week.
