winter-like storm for the first week of summer

A significant weather pattern shift is on its way beginning tomorrow for Northern California. An "atmospheric river" of moisture is aiming at us and will direct a potent (for this time of year) storm our way. A fairly weak storm will swing through tomorrow, giving Chico a slight chance of a rain shower and increasingly breezy conditions. The bigger, more powerful storm will come in early Monday and linger into Tuesday. Up to an inch of rain could fall in Chico between late Sunday and late Tuesday. Winds will be gusty from the southeast, with speeds up to 30 mph. Hold on, I have to go and check the calendar; is it June or February? Snow may even fall in the highest elevations of the Sierra Nevada, but generally above pass level. Is this what climate change looks like? Normally Chico averages about six-tenths of an inch of rain for the whole month of June- we may see almost double that amount in just two days! Here is Chico's seven day forecast from the National Weather Service: Today Sunny, with a high near 93. West northwest wind around 9 mph. Tonight Increasing clouds, with a low around 62.
