An increasing thunder threat thanks to the eastern Pacific.

Hurricane Linda off Baja California helps trigger a surge of moisture from the Gulf of California. This helps to boost rain chances over the next 72 hours. A 20% chance of storms is possible for Metro Tucson this afternoon, as highs peak in the upper 90s. Isolated storms can’t be ruled out overnight with lows dropping to the mid 70s.

Today’s Monsoon Prediction Index is 2 out of 10 for Tucson, indicating a low storm risk.

Storm development increases to the scattered variety Wednesday and Thursday, with metro rain chances at 30%. A few storms could be capable of locally heavy rainfall, especially along the International Border & in the mountains. Daytime highs reach the mid 90s.

Drier air enters from the north heading into the weekend, in response to high pressure parking over Nevada. Valley floors look to be thunder-free with the metro reaching triple digits. We could see a few storms pop up as you head back to work early next week, but most areas stay dry.

Gorgeous Gates Pass sunset, captured last night by News 4 Tucson viewer Andrea Lochner. You can even spot a slight sun pillar at the right, which is sunlight being reflected by horizontal-oriented ice crystals falling through the sky.
