Weather Forecast: Scattered Showers, Stronger Storm Friday

Published On: Mar 27 2014 08:08:16 AM CDT   Updated On: Mar 27 2014 12:29:23 PM CDT

After a very active day Wednesday, the Northstate can expect isolated to scattered showers today.  Our next storm system moves in Friday, bringing heavy rain and gusty south winds. 

(Recap of Yesterday's Tornadic Supercell) At approximately 3:00pm Wednesday afternoon a thunderstorm capable of producing a tornado developed prompting the National Weather Service to issue a Tornado Warning for Central Glenn County.  Four more Tornado Warnings were issued for the same storm eventually including Butte County.  The last warning was allowed to expire at 6:45pm.

Though surveys are still on going, the NWS believes that all tornado reports came from a single track tornado that may have lifted and descended to the ground multiple times.  This will still count as only  1 tornado.  As of this morning preliminary EF ratings place the tornado in Glenn county as a high end EF1 tornado.  Though there is a possibility of it receiving a weak EF2 rating.

The Tornado near Roseville, near Sacramento Wednesday, has been surveyed and received a rating of a high end EF0 rating.

The tornado from Tuesday in Butte county near Durham, has received the rating of a weak EF0 tornado.  

The Forecast today will continue to see scattered to isolated showers move in and out of the Northstate.  Also expecting a little more clearing for the valley floor.

Tomorrow, a stronger front will push in that will tap into a moist precipitable water plume from out of the sub-tropics.   This will bring in pockets of heavy rain Friday afternoon through early Saturday morning.  We are also expecting gusty south winds to accompany this heavy rain.

We could also get clearing quick enough Saturday afternoon to allow for thunderstorms to redevelop.

There will be a slight break in the weather on Sunday before another, colder storm arrives Monday.  Snow levels will likely dip closer to 3,000ft with heavy accumulations possible down to 4,000 ft if not lower.
