Sacramento's rare June rain falls short of predictions

As Sacramento residents tucked away damp umbrellas Monday and called for refunds on their deluge insurance, the National Weather Service said it wasn't over yet.

"The overall storm isn't as strong as the models were predicting a few days ago," Darren Van Cleave, meteorologist for the National Weather Service, said Monday afternoon. "We do have a stronger one forecast for early tomorrow morning, and it should be able to squeeze out few more tenths of an inch."

Between one-tenth and two-tenths of an inch of rain is predicted to fall on the Sacramento metro area from mid-morning today through the afternoon, proving a slightly stronger storm than the one that lurked above Sacramento on Monday.

Van Cleave said the early-week rain is a stream of moisture coming in from the ocean, but Monday's and today's storms are separate low pressure systems.

The first system had mostly left the area by Monday evening, with just a few lingering showers trailing behind.

Van Cleave said the abnormally high amount of moisture in the atmosphere didn't have enough orographic lift – rising motion in the atmosphere – to squeeze out the predicted levels of rain. However, the air traveled over mountains in some areas and had enough lift to push out more rain than areas without mountains, though not in the large amounts predicted.

Shasta County and some of its surrounding areas had more than 2 inches of rain, and places outside the Sacramento Valley received more than an inch.

Van Cleave said that as late as last Friday, models were still showing Monday's storm would be powerful. But it started to back off Saturday and then appeared to be a much weaker storm by Sunday.

Monday evening's model still showed today's storm should be as strong as previously predicted.

No snow was reported or confirmed related to the weather systems, he said.

Though Monday's scattered showers did not reach predicted levels, the amount that fell at Sacramento Executive Airport – .05 of an inch – broke a record for the date. Since it began keeping record in 1941, the airport had never recorded rain on June 24.
