Balmy in the mountains, giving way to a little rain

If you had the time to take a hike today, or hit the ski slopes, you'd find it's maybe 20 or 30 degrees warmer when you climb above 3,000 feet, says KPLU weather expert Cliff Mass.

That's because the atmospheric inversion is extreme today, trapping cold air in the cities of Puget Sound-opolis, while the warm air is trapped above.

Mass says it won't last. A bit of rain will break up our unusual dry spell, starting late on Saturday. Then, on Tuesday, the inversion ends, as a storm starts to mix the air.

"Since October first, we've been three inches below normal at Seatac," of precipitation, he says.

But Mass sees another inversion potentially forming soon after.
