Heat, Lightning and Rising Tides: What to Expect This Weekend

Weekend Forecast

• Thursday:
• Summer‑high temperatures in the upper 80s across inland areas.
• Saturday:
• Low 90s expected as a monsoon‑like pattern moves in from the desert southwest.
• Monday:
• Mid‑90s temperatures possible as the pattern continues.

Dry Lightning Alert

• What it is: Thunder and lightning without rain reaching the ground.
• Why it matters: Dry air near the surface with moisture high up creates conditions where lightning can strike while the sky remains clear.
• Fire risk: Still developing, but could elevate wildfire danger if instability increases. Current forecast deems the threat not severe yet; meteorologists will monitor closely.

Weather Drivers

• A high‑pressure dome is shifting eastward, ushering in dry air while moist southwest air wraps around it—fuel for the unstable atmosphere that produces dry lightning.

Coastal Impact

• King tides: Water levels will rise more than 1½ ft above normal.
• Advisories:
• Bayshore areas: Thursday 4 p.m. – July 16 4 a.m.
• Rest of Pacific Coast: Saturday – July 15
• Cause: Swell from Southern Hemisphere storms raising high tides.

Takeaway

• Expect typical summer heat, a potential dry‑lightning fire risk that’s still evolving, and higher tides affecting coastal communities. Stay informed, prepare for changing conditions, and exercise caution if you’re near fire‑prone or low‑lying areas.
