Area Forecast Discussion National Weather Service Hanford CA 325 AM PDT Sun May 1 2022 .SYNOPSIS... Windy conditions along the Mojave Desert Slopes until Sunday Night. A little cooler today as a dry trough enters the Great Basin. Much warmer by the middle of next week with dry weather expected to continue. && .DISCUSSION... Disturbance currently crossing the region is producing strong westerly winds over portions of Kern County. While the bulk of the energy from the disturbances passage is over the Great Basin (east of the Central California Interior), a portion of that energy is skirting the district. Enough jet-stream energy is currently moving across the district to generate wind gusts up to 50 mph. The strong winds are also getting support from the surface. The pressure gradient from KSFO to KLAS was currently at 12mb and is tight enough to provide for isolated wind gusts reaching advisory criteria. Therefore, until the disturbance exits the region tonight, will expect strong winds over the eastern portions of the Kern County Mountains. Otherwise, temperatures will see a slight up and down until mid-week when the area heats- up under a much strong ridge pattern. Satellite and upper air analysis is showing the disturbance over Southeastern Oregon and moving southeast. Confidence in the trajectory of the upper disturbance is high as Hi-Res ensemble mean upper-air analysis has it moving through the Great Basin today. Therefore, winds will be the biggest impacts as the region remains dry and temperatures return to near normal conditions. Ensemble mean and member consensus is to have the desert winds start to drop off after 5 PM PDT. This will coincide with the departure of the disturbances energy this evening as the advisory is expected to expire around 11 PM PDT. Once the disturbance exits the region, weak ridge will move through the region ahead of another disturbance following a similar path. While uncertainty is a bit higher on the possible trajectory of the second disturbance, will lean toward a Great Basin path. This will then allow for another strong wind event. Monday will see slight warming of temperatures with winds beginning to feel the effects of the next disturbance. Between Monday and Tuesday, the ridge exits and another trough moves through the region. Consensus among the ensemble members is high that similar winds will be observed on Monday and Tuesday to those currently occurring. Yet, the district will remain dry during the next disturbance along with minor temperature changes. The second disturbance is projected to exit the region later on Tuesday. At which time, winds will drop off and cooler conditions are felt. Ensemble cluster analysis shows a different story by mid-week as a strong signal points to a well defined ridge pattern. With only minor differences on possible ridge solutions, will expected good warming to occur as valley temperature reach into the 90 degree mark. While probability of exceedance is only around 50 percent of reaching the 90 degree mark on Wednesday, that percentage grows to just over 70 percent on Thursday. Therefore, the heat is on by mid-week before yet another disturbance provides another wave of cooling. && .AVIATION... Surface winds gusting to 45 knots across the Mojave Desert Slopes in eastern Kern County until 06Z Monday. Otherwise, VFR conditions will prevail throughout Central California for at least the next 24 hours. && .AIR QUALITY ISSUES... None.Source; NWS
