The hazard you need to know about before the weekend
Thursday Temperature Forecast Coastal Areas: Cool conditions ranging from the upper 50s to lower 70s. Bayside Areas: Mild and comfortable temperatures in the 70s. Inland Areas: Warmer conditions in the 80s Hot Spots: The interior southern Central Coast (including Lockwood, Bradley and Parkfield) has the highest chance to clear 100°F. Long-Term Outlook (Friday – Next Tuesday) Weather Driver: A high-pressure ridge over the Southern Plains will shift west toward the Four Corners region over the weekend. Interior Warming: This atmospheric shift will compress the marine layer, triggering a minor warming trend in the far inland valleys. (low - mid 90s over the weekend) Summer Routine: Despite the slight inland warmup, temperatures will hover near seasonal averages with a standard daily pattern of overnight fog rolling inland and burning back to the coast by late morning. A Beach Hazard Statement is in effect beginning Saturday, July 25 through Tuesday, July 28 for sneaker waves and dangerous rip currents.

Midweek temperature tumble
The peak of this week's heatwave is currently hitting its final hours tonight, with a Heat Advisory remaining active until 9:00 PM for the interior Bay Area. A major pattern change arrives at midnight, bringing a rapid cooldown, muggy overnight humidity and a return of thick coastal fog. Air Quality Alert for the East Bay until Midnight. Could be extended tomorrow. We will keep a watchful eye! Today was officially the hottest day of the week, with inland areas soaring into the 90s and local hotspots cracking 100°F. Tomorrow brings instant relief as strong onshore marine winds rush back into the region. Interior valleys will experience a significant drop, topping out in the comfortable mid-70s to 90 degrees. The Coast: Highly comfortable, crisp conditions will prevail with daytime highs staying in the mid-60s to mid-70s. Tonight's Muggy Fog & Drizzle Timeline (Pattern Change at Midnight) The Setup: A compressed marine layer is quickly rebuilding over the ocean, locking in high, muggy humidity tonight.

Fog and Friday Freshness
• Sunday sky watching: Tropical moisture from Hurricane Elida (well offshore and not a direct threat to California) combines with monsoon moisture to increase mid and high clouds Sunday into early next week. At this point, the forecast favors more clouds rather than rain, since the atmosphere still lacks enough instability for thunderstorms.

Cooler but high fire danger remains
A massive weather transition begins tonight as the current interior heat wave is replaced by an expanding, 1,500-foot marine layer by the weekend. This shift brings relief from hot temperatures, but introduces a brand-new wildfire lightning watch for early next week. Thursday Forecast • The Big Drop: The extreme heat wave officially ends tomorrow. A deep Pacific Northwest storm trough is moving toward the coast, forcing a surge of cooler ocean air inland.. • The Numbers: Temperatures across the interior will drop significantly, falling right back to comfortable, mid-July seasonal averages. Thursday's span from 63 at the Coast to 90 Inland.. Critical Fire Danger & Weekend Wind • Tonight's Threat: Elevated fire weather conditions remain critical across the interior and higher terrain through Thursday night. Mountain ridges are enduring roasting heat up to 20 degrees above normal, paired with bone-dry humidity.. • The Wind: Strong, punchy afternoon and evening onshore winds will remain breezy through Friday, howling through mountain passes like the Altamont Pass and Salinas Valley. Avoid any outdoor activity that could spark a flame. Winds 10-20 mph with occasional gusts to 30 mph.. Long-Range Outlook: Renewed Lightning Watch Next Week: A strong onshore wind pattern will lock in through the weekend, deepening the marine fog layer to a steady 1,500 feet. Expect near-to-below-normal temperatures and gray morning overcast that retreats to the beaches by lunchtime. • The Tropical Shift: We are monitoring a heavy pulse of tropical monsoon moisture surging north around a high-pressure system. • Dry Lightning Threat: While the heaviest threat of severe thunderstorms has shifted slightly eastward over the Sierra Nevada for Sunday and Monday, a thick deck of mid-to-high level tropical clouds will stream over the Bay Area. Any high-based storm that develops over the parched local hills will trigger dangerous dry lightning strikes capable of sparking sudden wildfires

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.
