Area Forecast Discussion National Weather Service San Joaquin Valley - Hanford CA 250 AM PDT Sat May 4 2019 .SYNOPSIS... Mainly dry and warm weather will persist today, although a few showers may develop near the Sierra Nevada crest this afternoon. An Eastern Pacific low pressure system will approach the coast of California Sunday afternoon. This storm system will be responsible for a cooling trend late this weekend into early next week, as well as an enhanced chance for precipitation, mostly in the Sierra Nevada and adjacent foothills. && .DISCUSSION... An upper-level ridge of high pressure will be centered over Southern California today. This ridge of high pressure will be responsible for maximum temperatures this afternoon of five to ten degrees above normal for this time of year. There may be enough atmospheric instability in place for a few showers to develop near the Sierra Nevada crest in the vicinity of Yosemite National Park this afternoon. A storm system will move eastward through the Eastern Pacific Ocean tonight and Sunday morning. This low pressure system will approach the coast of California Sunday afternoon. The storm system should stall Sunday night, before progressing southeastward Monday and Monday night. A few strong thunderstorms are possible in the Southern Sierra Nevada and adjacent foothills Sunday afternoon, Sunday evening, Monday afternoon, and Monday evening. Gusty winds are likely in the Kern County mountains and desert, as well as in the west side hills of the San Joaquin Valley Sunday afternoon, Sunday evening, Monday afternoon, and Monday evening. Rainfall amounts should be less than one tenth of an inch throughout the San Joaquin Valley Sunday afternoon into Monday night. Much of Kern County could remain free of precipitation late this weekend into early next week. The aforementioned low pressure system will progress eastward into the Desert Southwest Tuesday. Lingering atmospheric instability may assist to trigger shower development over the Southern Sierra Nevada Tuesday afternoon. An upper-level trough of low pressure will drop southward out of the Intermountain West and into the Great Basin Tuesday night and Wednesday. From this point forward, forecast confidence is low as it is highly dependent on where and when an area of low pressure aloft forms in the base of the trough. If this upper-level area of low pressure develops over the Great Basin and moves southwestward, much of period from Wednesday night through Saturday night could be unsettled. On the other hand, if the area of low pressure aloft forms south of Central California, inclement weather may only be confined to Thursday and Thursday night. For now, the forecast will be based on a blended solution, with a trend toward climatology.
