Hey Hey Giovanni here! Your weatherguy. What a fun packed week of weather we just had. We started out warm with strong High pressure that brought us us warm and dry weather, until midweek when a cold wet and windy storm brought us 1.2" of rain and over 2ft of snow above 7000ft. We even had snow flurries down to 3100ft late Wednesday night, but it all melted away below 4000ft by Thursday afternoon. Although this storm was very dynamic with the deepest Low pressure we've seen all season, the storm lacked a deep moisture pool and just not enough cold air to really make a huge impact in the rain bucket. A follow up storm on Friday only brought just over 0.30" of rain before we dried up again for the weekend. Not the wettest week we've seen all year, but at least it did rain.

 Weekly Forecast: The coming week will start out dry, with only a few high clouds as the storm track will remain mostly to our north through the coming week. Long range forecast models are hinting of a storm arriving next Saturday, but I see this storm splitting, shunting the moisture north, leaving us with a slight chance of showers. I don't see the jet stream reconsolidate itself across the eastern Pacific until the 29th or so with El Niño enhanced storminess returning to California and remaining with us for much of March.

*Statewide Sierra snow pack is at around 96% of normal for this date!

El Niño update: An overall quiet period over much of the west coast will return this coming week. Global forecast models are now fairly certain of a major build up of storminess starting the first week of March.

EL Niño impacts: Climatologists say we are experiencing of one the strongest El Niños on record. During strong El Niños, the subtropical jet stream that brings wet storms to southern Mexico and Central America moves northward, creating a constant flow of storms over Southern California. Only exceptionally strong El Niños are powerful enough to shift the entire jet stream to cover Northern California, giving the southern California double its rainfall and Northern California double the Sierra snowpack if not more, Those severe El Niños last hit in 1982-83 and 1997-98.

The latest weekly El Niño indices are listed below. El Niño is HERE! Conditions are present and it will last into early spring 2016.

My BloomSky this afternoon!

The storm track will remain to our north this week!

The jet stream will bring us mostly sunny skies with a few high clouds.

Forecast models look to keep High pressure off our coast through the week.

The precipitation outlook map for the coming week is looking mostly dry across much of NorCal with the exception of the far north coast.  

Have a great week and make sure to follow my
