April 4, 2020 - The National Weather Service Hanford Office reports a significant storm system will impact Central California Sunday through Monday.
A Winter Storm Warning is in effect for the Southern Sierra Nevada above 4,500 feet Sunday morning through Monday afternoon.
The majority of this precipitation will fall Sunday afternoon and Sunday night.
National Weather Service Hanford CA 416 AM PDT Sat Apr 4 2020 .SYNOPSIS... A storm system will bring unsettled weather this weekend and through early next week, with heavy mountain snow and appreciable valley rain on tap for Sunday and Monday. Dry and warming conditions will return for the latter half of the week. && .DISCUSSION... It`s a seasonably cool morning across central California under mostly clear skies as a west to northwest flow prevails across the region. Satellite and radar loops show a low pressure system and associated precipitation swinging into the northern California coast. This system will impact our weather beginning today as it continues to push inland. Models spread precipitation southward today, affecting northern portions of our area by this afternoon. The system and more significant precipitation will pass mainly to our north and we should see just light rain and higher elevation snow today, remaining generally north of Kern County. A deeper developing low pressure system dropping out of the northwest Pacific behind this initial disturbance is progged with good model agreement to drop slowly southward off the California coast by early Sunday through Monday. This system will bring more significant precipitation to our area by late tonight/early Sunday morning. The heavier precip will continue into Monday with the slow southerly drift of the system. Total snowfall accumulations Sunday through Monday will be as much as 2 to 3 feet in higher elevations of the Sierra and around a foot as low as 4500 feet. A Winter Storm Warning has been issued for much of our Sierra zones for Sunday morning through Monday afternoon. Model solutions are not too dissimilar in timing and trajectory as the system swings inland near southern California Tuesday into Wednesday. This will keep unsettled conditions over much of our area into the middle of next week, with a few showers lingering over the mountains into Thursday as the system pushes off to the east. High pressure building in behind the departing low pressure system will will bring a warming and drying trend for the end of the week.
