Area Forecast Discussion National Weather Service San Francisco Bay Area 156 PM PDT Thu Apr 9 2020
SYNOPSIS. Isolated showers may linger south of the Bay Area into tonight with areas elsewhere remaining dry. A gradual warming trend will then begin tomorrow continuing through the weekend as high pressure slowly builds over the region and the upper low continues to push further inland. More seasonable temperatures and drier conditions will persist into at least early next week.
DISCUSSION. as of 01:56 PM PDT Thursday . Satellite imagery shows the region remains under cloudy skies as the upper low that gave us our most recent rainfall continues to spin over southern California. This pesky and persistent low has been very slow to exit the region keeping isolated showers mainly south of the Bay Area into this morning. Over the past 12 hours as much as an additional quarter of an inch of rain has fallen over the Santa Cruz and Santa Lucia Mountains. Forecast models show one last possible push of scattered showers across the region tonight, again most likely south of the Bay Area, before the upper low finally progresses southward and then inland into the southern United States.
For those who are curios, just about the entire Greater Bay Area over the past two weeks has seen above normal precipitation for this time of the year with some locations exceeding their entire April normal rainfall in just over a week. The Monterey Airport did so in a single day with 1.71" falling on April 5th. The normal April rainfall for the airport is 1.12". However, most of the area is still about 40 to 55 percent of normal for the water year so far. After a fairly wet and cooler start to April, conditions look to warm and dry out beginning tomorrow.
The upper low will finally move eastward as an upper ridge builds over the eastern Pacific. Most areas tomorrow away from the coast will be in the mid to upper 60s with some locations possibly reaching 70 degrees. Coastal areas can expect temperatures in the upper 50s to mid 60s. Gradual warming will continue through the weekend as the ridge slowly shifts closer to the west coast. More widespread low to mid 70s are expected across the interior for the latter half of the weekend and into early next week with some areas even a few degrees above seasonal normals. Looking into the longer term, the CPC 6-10 and 8-14 day outlooks both show California with above normal temperatures and below normal precipitation. Both GFS and ECMWF ensembles show dry conditions persisting into at least the middle of the month.
AVIATION. as of 11:08 AM PDT Thursday . for 18Z TAFs. Most airports reporting VFR-MVFR except very locally and briefly IFR, otherwise seeing improvement in ceilings and visibilities since early morning. Satellite imagery still showing a fair amount of clouds rotating east to west from the Sierra Nevada and Central Valley, also remnant low clouds from a southerly surge on the coastline. Not sure how well model output is handling boundary layer relative humidity and cloud cover which will be subject to a relatively drier continental influence as the wind flow is from the east. TAFs are otherwise near persistence, there may be another period of light rain developing from the East Bay to the South Bay and over the north Central Coast tonight and early Friday.
Vicinity of KSFO . Recent observations showing VFR with a higher ceiling since early morning. Low confidence on duration of east wind today, recent 5 minute obs show east wind at 8 knots. Wind shift to southwest or west possible in the late afternoon or evening.
SFO Bridge Approach . Similar to KSFO.
Monterey Bay Terminals . VFR, light and variable winds except southeast up to 14 knots at KSNS. East winds generally decreasing to light and variable with light southeast winds tonight. A passing shower possible tonight and early Friday.
MARINE. as of 10:39 AM PDT Thursday . A weak surface low pressure circulation is located over the southern outermost coastal waters and continues to move southward. Winds will be from the south over the coastal waters and east to southeast over the bays today, shifting to northwest on Friday and becoming gusty over the weekend. Moderate northwest swell will persist through the rest of the week along with a long to moderate period southerly swell.
MTR WATCHES/WARNINGS/ADVISORIES. Tngt. NONE.
