Warm, Cloudy, Muggy with Low Risk of Dry Thunderstorms and Elevated Fire Danger
Happy Sunday Everyone! Warmer, muggy weather is in store today as monsoonal moisture moves into the Bay Area through Monday. While the chance of thunderstorms remains low, any storms that do develop could produce dry lightning with little rainfall, increasing the risk of wildfire starts due to extremely dry vegetation. A Coastal Flood Advisory also remains in effect during periods of high tide through Thursday, with minor flooding possible in low-lying shoreline areas. The hottest weather is expected Tuesday and Wednesday before temperatures ease slightly later in the week.

Fire danger escalates now through Monday
The tropical monsoon has arrived, with dry lightning threats, coastal flooding and a building inland heatwave impacting the region simultaneously. Highs today ranged from 64 in Pacifica to 94 in Fairfield. • The Storm Threat: Monsoonal moisture is advancing rapidly northward into the Bay Area. • Radar tracking mid-to-high-level tropical clouds and virga (rain completely evaporating before touching the ground). • The threat for dry lightning and gusty thunderstorm wind gusts is active tonight through Monday morning. • While the chance of a lightning strike remains low, any strike could easily spark a wildfire. • By Monday afternoon, a slight chance of actual wetting rain showers. Coastal Flood Advisory (Tonight – Thursday) • Sunday Forecast: Coast cool in the 60s, bayshore 70s, and the inland in the 80s to mid-90s. • Muggy Nights: The incoming tropical monsoon clouds will act like a giant greenhouse blanket tonight and tomorrow night. Overnight lows in the 60s away from the Coast.

Warmer, muggier weekend
Strengthening high pressure over the West will bring a summertime warm-up and increase fire weather concerns. Low clouds will linger along the coast, while monsoonal moisture spreads subtropical high clouds across the Bay Area. For today, expect highs in the 60s along the coast, 70s and 80s around the Bay, and 90s inland. By Sunday and Monday, the combination of monsoonal moisture and limited instability could produce isolated dry thunderstorms, increasing the risk of lightning-sparked wildfires and gusty, erratic winds. Meanwhile, a Coastal Flood Advisory remains in effect through Thursday morning. Higher-than-normal tides could lead to minor flooding in low-lying areas along the coast and around the Bay during high tide.

Weekend weather changes you need to know about
1. King Tide Flooding: 1.7 Feet of Inundation A Coastal Flood Advisory remains in effect for minor shoreline flooding. Low-lying parking lots, coastal parks, pathways and roads will experience saltwater flooding nightly. The advisory runs until 4:00 AM Wednesday morning for the Pacific Coast beaches, and remains active until 4:00 AM Thursday for the inner San Francisco Bay shoreline. 2. Fire Weather Watch: Tropical Monsoon Surge (Late Weekend) On Saturday night through Sunday, a deep plume of monsoonal moisture surges from the Gulf of California. If these clouds manage to spark thunderstorms, any falling rain will evaporate in the hot, bone-dry lower air before touching the soil (virga). This creates a dangerous "low probability, high impact" scenario for a dry lightning storm. Because regional plants and brush are rapidly drying out, dry lightning hits combined with erratic, gusty thunderstorm winds could instantly ignite explosive wildfires. Pockets of high-based rain showers may slide through Monday.

Slightly cooler forecast
Your Friday forecast features slightly cooler temperatures. The morning fog near the bay will eventually retreat to the coast. Highs should range from the low 60s near the shoreline to the upper 80s inland. Temperatures will rebound this weekend. Moisture will move into the area from the south. The monsoonal flow will lead to humid conditions and instability that could trigger dry thunderstorms (fire danger concerns Sun - Mon).

The latest on the possible El Nino this year
A Coastal Flood Advisory is in effect for minor high tide flooding. This advisory is thru NEXT Thusday. A Beach Hazards Statement remains strictly active through Friday 5 PM. Stay off jetties and never turn your back on the ocean. High pressur building into the Desert Southwest, compressing our natural marine layer The Coast: Kept chilly in the 60s under persistent marine cloud blocks. Around the Bays: Comfortable and breezy with highs in the 60s to 70s. Inland Valleys: Warming rapidly into the 80s to mid-90s. I am forecasting 100 degrees from Discovery Bay and Brentwood to Fairfield on Monday. Expect 90s Inland for two weeks. Interior Hotspots: The absolute warmest interior locations of Monterey and San Benito counties have a greater than 60% probability of cracking 100°F Nightly Inversion: While lower elevations drop into the cool 50s overnight, the building ridge will trap heat in our higher elevations and mountain peaks, keeping thermal hillsides stuck in the warm 60s and low 70s.

Fun in the sun, but there is a catch
Warming Trend: Highs rise Thursday into the weekend, reaching 80s - 90s inland, up to 100°F+ in hot spots well into the Interior Valleys, and 60s - 70s at the coast. Hottest days will be Saturday, Monday and Tuesday. Once temps soar, it will remain above average for 15 days! Beach Hazards Statement: In effect through Friday 5PM. A long-period southwest swell creates a high risk of dangerous sneaker waves and strong rip currents. Stay off rocks and jetties and never turn your back on the ocean. Coastal Flood Advisory: Up to 1.7 feet of minor tidal inundation is possible in low-lying shoreline areas. Advisoryis in effect from tomorrow (Thursday for 1 full week!) Storm & Fire Risk: Monsoonal moisture brings a chance of dry thunderstorms and elevated fire danger Sunday through early next week.

Wednesday Warmup
Enjoy tonight's cool air, because the warmer weather back tomorrow. For Wednesday: The Desert Southwest ridge is shifting directly over Southern California, compressing our natural marine layer down to a shallow 1,000 feet. Thursday & Friday Peak: Temperatures will jump 4 to 5 degrees. The Coast & Bayshore: Shielded by the ocean, holding comfortably in the 60s and 70s. Interior Bay Area: Baking in the mid-to-upper 80s, with far North Bay and East Bay valleys pushing into the 90s. Interior Central Coast: Extreme heat will hit the valleys of southern Monterey and San Benito counties, with temperatures cracking the triple-digits at 100°F to 104°F A Beach Hazards warning is locked in today through Friday.This long-interval swell creates an exceptionally high risk for deadly sneaker waves and dangerous rip currents Sneaker waves strike without warning during peaceful lulls, surging dozens of feet up dry sand to sweep beachgoers into the freezing surf. Never turn your back on the ocean!

Closing out the holiday weekend below average
A passing upper-level trough is bringing cooler-than-normal temperatures across the Bay Area and Central Coast today and Monday, with highs mostly in the 60s near the coast, 70s in the Bay, and upper 80s to low 90s in the warmest inland areas. The marine layer stratus continues to expand overnight into the valleys, then retreats back toward the coast each afternoon, keeping coastal skies gray and inland conditions variable. A very slight chance of isolated showers remains mainly for the Central Coast and parts of the Bay Area through late morning, but widespread rain is not expected due to dry air aloft limiting instability. By the second half of the week, a warming trend builds as the trough exits and high pressure returns, bringing drier skies, lighter marine influence, and gradually rising temperatures.

Terrific Thursday, Fabulous Friday
Thursday Forecast (Today's Final Chill & Microclimates) Seasonably Cool Today: One final day under the storm trough means temperatures remain below seasonal July averages. Coastal areas will stay stuck in the 60s, while inland valleys manage the 70s to 80s. Pacifica Southward Cloud Lock: The marine layer will stay stubbornly locked in place today for many coastal communities south of Pacifica. Monterey Bay Cloud Breaks: Unlike earlier this week, the thick clouds over the Monterey Bay will mimic yesterday, giving viewers decent afternoon sun breaks before the fog rushes back inland tonight. Extended Outlook: Summer Heat Rebuilds Next Week Mid-Week Warmup: The Climate Prediction Center is strongly favoring a return to true summer conditions across California through next week.

From June Gloom to No Sky July
Midweek Forecast (Wednesday & Thursday Cooler) Seasonably Cool: Until the weekend ridge arrives, the lingering storm trough will hold our temperatures a few to several degrees below normal averages for the end of June, into our first day of July. Wednesday Temperatures: Coastlines will remain locked in the chilly upper 50s to near 70°F. Inland valleys will actually drop a few degrees cooler than today, landing comfortably in the 70s to low 80s. Far interior hotspots (like Contra Costa and eastern Monterey counties) will top out in the upper 80s, flirting with the 90-degree mark. Afternoon Breezes: Expect the usual punchy, breezy onshore winds to ramp up every afternoon and evening through Thursday. West and southwest 10-20 MPH.
