Area Forecast Discussion National Weather Service San Joaquin Valley - Hanford CA 345 AM PDT Mon Jun 11 2018 .SYNOPSIS... A ridge of high pressure building across California will bring warming temperatures for the next few days, with widespread triple digit highs expected by mid-week. Dry conditions will prevail throughout the forecast period with a cooling trend possible by the end of the week. && .DISCUSSION... The trough of low pressure which brought gusty winds and highs around 15 degrees below climo across central CA continues to move away from the area, allowing a high pressure ridge to move into the region. This transiting ridge will bring a warming trend to our area for the next few days, with temperatures returning to around normal today and continuing to increase through Wednesday, when highs will be into the triple digits at most SJ Valley, lower foothill, and desert locations. The recent round of cooler than normal conditions will help to accentuate these increasing temperatures as much of our area outside the higher elevations climbs into moderate heat risk category for persons sensitive to the heat. People should avoid strenuous activity during the hottest part of the day and stay well hydrated during this period of increasing temperatures. Models are similar in moving another low pressure center inland near the Pac NW by Thursday and digging a trough into California through the end of the week as additional shortwave energy drops southward. There are some differences in the details of the developing trough but general agreement in swinging a closed low to near the Great Basin region by the start of next week. This will bring a return of cooler temperatures by the weekend, with highs dropping back a few degrees below climo. The forecast remains dry throughout the period, as moisture lifting northward with tropical system Bud is swept eastward by the developing trough later this week.
