(tdy-Sun), 19/202 PM.
In general temperatures today are either the same or a few degrees cooler than yesterday. Expecting one more day of similar temperatures before the current high pressure system starts shifting into AZ which will initiate a brief cooling trend over the weekend. Most areas except the far interior will experience 5-10 degrees of cooling this weekend, though that still keeps highs 10-20 degrees above normal. A shallow marine layer has begun to form over the coastal waters and many beaches will start out with dense fog the next few days and that will help cool off the coastal areas.
In the meantime, it continues to be very hot with temperatures 20-30 degrees above normal Heat Advisories and Extreme Heat Warnings remain in effect through Friday. Based on the current forecast, there is only about a 30% chance of extending heat advisories into Saturday, and those would most likely be in the inland areas.
(Mon-Thu), 19/215 PM.
Temperatures will slowly start to increase across inland areas Sunday and for coastal areas on Monday. Not expecting temperatures to be as hot as this week, but still 15-20 degrees above normal, with a less than 5% chance of reaching 100 in the valleys.
Additional rain possibilities still look very bleak through the end of the month. Some models indicate some very light rain in early April but amounts are mostly under a tenth of an inch.
