Area Forecast Discussion National Weather Service Hanford CA 400 AM PDT Sat Jun 8 2019 .SYNOPSIS... A warming trend will begin today with temperatures climbing to well above normal early next week. Temperatures will trend down late next week but will remain a little above normal. Otherwise, dry weather will prevail with mostly sunny skies. && .DISCUSSION... An upper trough is tracking eastward over the Pacific Northwest this morning as a cooler air mass is in place across the region. Temperatures on Friday were generally around 4-8 degrees below normal with a few locations in the San Joaquin Valley not even reaching 80 degrees. Breezy conditions across the SJV yesterday have tapered off for the most part. But the wind continues in parts of the Kern County Mountains and Desert, where local gusts around 35 mph are occurring. These winds will gradually diminish through the morning as the surface pressure gradient is relaxing. The trough will push east over the northern Rockies today as a ridge of high pressure begins to build in from the south. Temps will warm up a few degrees today then jump around 10 degrees higher on Sunday with upper 90s common across the SJV. Further warming early next week will result in widespread triple digit heat across the lower elevations. Highs next Monday and Tuesday are forecast to be 10-15 degrees above climatological normals. An Excessive Heat Watch has been issued for both Monday and Tuesday as heat related illnesses such as heat exhaustion and heat stroke will be possible. People may be tempted to seek out the water in area rivers to cool off during the heat. But the heat will also bring increased snowmelt in the Sierra resulting in faster and deeper flows. These cold and swift waters can be very dangerous. Models bring an upper trough in from the eastern Pacific around midweek to begin a cool down. Highs are forecast to drop a few degrees each day Wednesday through Friday, ending up a little above normal still. Winds will increase again with the passage of the trough. There is a very slight chance for some afternoon showers along the Sierra crest later next week, otherwise dry weather will prevail.Source: NWS
