If it's not raining, why is it flooding?
video

A unique double-threat of historic summer high tides and deadly sneaker waves will impact local coastlines through the middle of the week.   1. MORE Historic Summer Tides. Nightly localized flooding will continue along low-lying areas of the San Francisco Bayshore and Pacific Coast. Sunday's new moon and lunar perigee, combined with warm ocean water and rising sea levels, are pushing tides up to 2.0 feet above normal .This event is on track to become the highest summer tide ever recorded in the Bay Area. Coastal Flood Advisory is in effect until early Wednesday morning for the inner Bayshore. Avoid parking or driving in low-lying coastal areas.  2. Beach Warning: A Beach Hazards Statement is active across all Bay Area Pacific beaches through late Tuesday night. Monday temps will be holding from 65 at the Coast to 90 Inland.   The west side of San Francisco (including the Sunset and Richmond districts) and the immediate Pacific coast will remain locked in this foggy, sunless pattern for the next few days.

Slightly cooler

Low clouds will return to the coast and bay Sunday morning.  The clouds should clear to near the coast later in the day.  Our cooling trend continues.  Highs should range from the low 60s to the low 90s. Another Beach Hazards Alert begins Sunday.  Swell will be building from the south.  Waves could approach 10 feet in select spots.

Summer like pattern over the Bay today

Partly cloudy and mild to mostly sunny and hot today depending on what part of the Bay you will be in.  Upper 60s can be expected near the shore while inland areas will soar into the 90s once again.  An additional dip in temps. is in the forecast for tomorrow. 

Heat Advisory For Saturday's World Cup Match In Santa Clara
video

The Heat Advisory for our East Bay Inland areas and Santa Clara Valley including San Jose has been extended to 7PM SATURDAY. This includes for the World Cup action in Santa Clara with a high of 88 degrees.  A Coastal Advisory is in effect from 7 PM Saturday until 3 AM Tuesday and this is the interesting part... If you live or drive near the San Francisco Bay shoreline, you need to watch out for saltwater flooding on the roads over the next few days, especially during the late night hours. We are seeing a rare combination of a New Moon and the Moon making its closest approach to Earth. This cosmic pull, combined with warmer ocean water and rising sea levels, is creating a massive 'bulge' in the ocean. Tides will spike up to 2 feet higher than normal. While this isn't as severe as the major storms we saw back in January, it is on track to be the highest summer tide ever recorded in the Bay Area. Expect low-lying parking lots, docks and coastal roads to see minor flooding nightly through the middle of next week.  A Beach Hazard Statement is in effect for 3 AM SUNDAY to 3 AM Wednesday. Another interesting fact...The waves will be only 4 to 6 feet, but don't let that fool you! These are not necessarily giant breakers, but a long period swell can pack tremendous energy, sending waves farther up the sand and creating dangerous rip currents. (Good story here!) (edited)  Now, the forecast! Saturday: Inland Heat Advisory in effect with mid 90s expect.  Coastal areas locked into a classic summer pattern with stubborn morning low clouds that clear by midday. Sunday (The Peak Flooding Night): A weak low-pressure system pushes further onshore, giving the natural air conditioning an extra boost. This will be the coolest day of the weekend. 92 in Livermore. However, Sunday night brings the absolute highest tide of this event, peaking at a near-record 1.9 to 2.0 feet above normal right around 11:10 PM. 

Cooling begins
video

Thursday was the hottest day of the week. Heat Advisories are still in effect through Friday evening for the inland areas and the South Bay.  A change in the wind flow, from the south, will lead to a cooler Friday forecast.  Highs should range from the mid 60s near the coast to the mid 90s inland. The cooling trend will continue this weekend.

Hot Thursday forecast
video

Our warming trend continues.  Heat Advisories have been posted for most of the Bay Area Thursday afternoon and evening.  Inland spots will head into triple digit territory for the first time this year. In addition to the heat, dry northerly winds will also boost the fire danger.  A Red Flag Warning will be in effect for parts of Lake County, North Bay Hills, and East Bay Hills (begins: 11 pm Wednesday  ends: 9 am Thursday). The Beach Hazards Alert remains in place for the coast as energy from a southerly swell continues boost wave heights.

From clouds to heat
video

A weak system could produce a few sprinkles or spotty drizzle Tuesday morning.  The clouds will be clearing later in the day.  Highs should range from the low 60s to the mid 80s. Our weather focus will then shift to the heat.  We are expecting a big temperature bounce Wednesday.  Thursday should be the hottest day of the week.  Some inland areas could approach 102 degrees. Dry winds will also be increasing from the north.  Fire danger, as a result, will  be increasing by midweek.

Heating up later in the week
video

A weak system will approach the Bay Area Monday.  High clouds will  be increasing throughout the day.  Stronger winds in the afternoon forecast too.  Gusts could exceed 30 mph.  Highs should range from the upper 50s to the upper 70s. A big pattern change later in the week!  Temperatures will be soaring Wednesday and Thursday.  Inlands areas could approach triple digit territory.   The windy and dry pattern will also boost the fire danger.  A Fire Weather Watch has been issued for parts of Northern California.

Sunny and seasonal today

Happy Sunday Everyone! Mostly sunny skies and seasonal temperatures will take center stage for your Bay Area Sunday, ranging from 60s at the coast, 70s bayside and low 80s inland.  A system will move through early in the week increasing our cloud cover and offering a chance of drizzle and sprinkles Monday into Tuesday.

Under mostly sunny skies, temps. will soar into the 90s inland today, 70s - 80s around the bay, 60s-70s along the coast with a Beach Hazard Alert until tomorrow morning for an increased risk of RIP Currents and Sneaker Waves. A notable drop in temps. on the way for the weekend and beyond. 

Friday Sizzle to Monday Drizzle

The Forecast: Day-by-Day Tonight: Skies remain mostly clear inland. The coastal fog machine will stay confined mostly to the Monterey Bay region and parts of the SF Peninsula by Friday morning. Friday (The Peak Heat): Friday is the hot one. Inland valleys will easily soar back into the 80s and 90s. Only the furthest inlkand spots will hit a "Moderate Heat Risk," while beaches stay in the 60s thanks to a refreshing afternoon sea breeze. Beach Hazard Statement in effect Friday through Saturday 9 AM for sneaker waves and rip currents. The Weekend Shift: The cold front hits Saturday. Temperatures will plunge 5 to 10 degrees below seasonal averages for both Saturday and Sunday (but still a couple degrees above average inland!).

A slight chance of actual light rain showers for the Bay Area northward. 

From June Gloom To June Jump!

We are on a weather roller coaster. After a massive temperature jump today, Thursday and Friday will bring the peak of this week's early-summer heat under clear, sunny skies. However, a cold storm system from the Gulf of Alaska is timing its arrival perfectly to knock temperatures down significantly just in time for the weekend. Short-Term Forecast (Tonight through Friday) Tonight: The coastal fog machine is starting back up, but it will remain shallow. Expect patchy low clouds to hug the San Francisco Peninsula and the Monterey Bay region by Thursday morning. Thursday: Morning clouds clear quickly for a stellar, sun-drenched afternoon. Highs will range from the 60s on the coast, the 70s and 80s around the Bay and a hot upper 80s to mid-90s in the far interior valleys. Friday: A true "rinse and repeat" day. Temperatures will hold steady as the warmest day of the week, offering perfect patio weather across the inland neighborhoods. Long-Term Forecast (The Weekend through Next Tuesday) The Saturday Shift: A weak cold front pushes south through the area, bringing a sudden, 10-degree drop in temperatures across the board. (But, still very nice weather!) The Weekend Air Conditioning: Strong, gusty onshore winds will kick up on Saturday and Sunday afternoon. The marine layer will deepen dramatically, bringing back widespread gray mornings and the threat of damp coastal drizzle. Early Next Week: The cooling trend deepens into Monday and Tuesday, keeping temperatures well below normal for June.

Winds Whipping Up Wednesday
