DISCUSSION

Today's highs were a bit lower than yesterday's, or by several degrees, and the warmest locations reached in the mid to upper 70's. Temperatures on Wednesday will trend upward with even warmer temperatures by the weekend. Highs reach into the 80's at the warmest locations until Friday and will continue to rise over the weekend. So, enjoy the pleasant weather while it lasts, even though the calendar says March!

The ridge of high pressure will be strong over the region over the next several days with little sign of it moving for awhile once it becomes established. By next week, the hottest temperatures of this year so far are on tap. There is a high probability of highs in the 90's in the Kern County desert (80-90 percent on Monday), with still a good chance of highs at least 95 degrees (60-70 percent). As for the Central Valley, there is a low to moderate probability of highs in the lower 90's by Monday. High temperatures in the 90's this time of year will at least set daily record maxima. Temperatures climb upward even further on Tuesday into next Wednesday, and minimum temperatures will also rise. Forecast minimum temperatures remain relatively cool, but milder; low heat risk is shown for the San Joaquin Valley. A moderate heat risk exists for the Kern County desert, while temperatures will be hotter with warmer overnight lows. Continued warmth lasts beyond the end of the forecast period, or into the latter part of next week, based on the latest CPC outlooks. Dry weather will also prevail for at least the next seven days.
