An unusually strong summertime #AtmosphericRiver brought AR 3 conditions and heavy rainfall to portions of western Washington last week. #WAwx See our latest quick summary for a brief synopsis of this event: cw3e.ucsd.edu/wp-content/upl….

#PickettFire - Update: The fire is approximately 1200 acres with a continued moderate rate of spread. Our partners from Napa County Sheriffs Office have issued evacuation warnings and orders. Visit protect.genasys.com/search for information

Temperatures return to within 5° of average on Saturday. Heat risk will be mostly in the Low category, Moderate at worst. The hottest temperatures will fall well short of 100°. But NWS still has much of the Bay Area under a Heat Advisory. Absurd.

So relieved — the high today in San Jose was 77°. 5 degrees below-average. Thank God that Heat Advisory was still in effect.

Two years ago today we launched our augmented reality weather environment. Today I used those tools on the CBS Evening News to track extreme heat, dry lightning, and a quiet (for now) pattern in the Atlantic. Looking forward to doing more, as new data is made available to us!

Almost 4,800 cloud-to-ground lightning strikes this morning! While we did see some in the Bay Area, the vast majority of the strikes were in the Central Valley. The best chance of storms later today will develop in the Sierra, but we’ll keep an eye on the radar just in case!

Scattered showers and thunderstorms will move south-to-north into the Bay Area on Wednesday. Total rainfall will be modest, but brief downpours could make roads slick, and you don't want to be caught in the open when there's lightning in the area! #CAwx

The last 2 days of lightning across our area. Data provided by Earth Networks.

Ground stop at SFO due to “Weather / Wind” — but it’s not windy (especially by SFO standards). Does a shift to an easterly wind bring everything to a halt? Doesn’t make sense…

On Monday, our forecast for next week showed partly cloudy skies. 24 hours later, that had changed to a 70+% chance of rain! What changed? I got a little nerdy in our 11pm newscast last night to explain how everything in the atmosphere is connected... #CAwx

Social media always goes a little crazy with our first chance of rain each season. I took some time last night to address some misinformation… #cawx

Absolutely pouring rain in Danville, CA #cawx NWS Bay Area 🌉 Rob Mayeda Paul Heggen @paulkpix.bsky.social

Decent rainfall totals so far, with more light to moderate rain on the way tonight and tomorrow! #CAwx

Tornado Warning for San Luis Obispo county, from San Luis Obispo down toward Santa Maria. Potential waterspouts offshore could move in as tornadoes. We may see a few of these tonight and tomorrow across So Cal.

Just to put a bow on the storm from earlier this week — not bad at all for mid-October!

NHC forecast track for #Melissa looks disastrous for Jamaica. 48+ hours on the right-hand side of a major hurricane? Yikes. Wind damage would be substantial with this scenario, but I’m more concerned about the potential for literally FEET of rain.

Tonight on CBS News 24/7 Prime/Time, I talked about the impacts Hurricane #Melissa will bring to Jamaica, Haiti and Cuba this week. This will be the strongest hurricane on record to hit Jamaica — the last major hurricane to make landfall was Gilbert in 1988.

I mean, his name *IS* Leo…

Get ready for a wet and windy Wednesday morning commute! Widespread flooding isn't likely, but a few flood-prone intersections could collect enough water to be problematic. Bigger issue looks like the wind energy with this system, causing power outages and downed trees/branches.
