California Storm

October 24th, 2012 at 2:24 am by under Bill's Blog, Weather

   They had their chance to get the boats out of the water!  This is Lake Tahoe after an early season snowfall.   Prosser Creek reported 30″ of new snow.  Alpine Meadows had 22″ and Mt. Rose checked in with 18″.  More snow totals here.  (Photo from Obexer’s Marina webcam – click the pic to enlarge).  3.5″ of snow fell at Davis Lake WA.    Five relatively small tornadoes touched down in N. California on Monday.  That tied the most tornadoes ever in the state of California in a single day.   The twisters damaged dozens of homes and knocked over a semi truck, but no injuries were reported.  Three of the tornadoes were rated EF1 with 100 mph winds.  The Yuba City tornado was on the ground for 20 minutes along a 3.5 mile path.  That twister caused some building damage and one outbuilding was lifted off the ground and carried 200 feet.

High temperatures Tuesday:  81 Louisville KY and Columbia MO, 91 Wichita KS, 95 Gage OK….73 Las Vegas, 52 Seattle, 53 Portland OR, 50 Boise, 28 Great Falls MT, 32 Yellowstone NP, 21 Calgary and 17 Grand Cache Alberta.   The low temperature was +7 at Stanley ID.  It’s already real cold in Alaska.  Arctic Village reached -20F Tues. AM, Gulkana was -14.  Fairbanks had a high/low of 7/-6.  Grand Rapids had the highest rainfall total on the evening Selected Cities Summary (about 145 cities in the U.S.).

    “The twisters damaged dozens of tornadoes”… That sounds intense! ;) (Of course, I would honestly do the same thing if I was typing something up at 2 in the morning!).

    NOW FOR THE SYSTEM THAT MAY BRING US PRECIPITATION IN THE TUESDAY
    TIME FRAME. THE ECMWF SOLUTION HAS BEEN RATHER CONSISTENT FOR
    SEVERAL DAYS NOW ON PULLING THE SYSTEM BACK WESTWARD AS THE NORTHERN
    STREAM TROUGH GOES NEGATIVE TILT. GIVEN THE SUPERIOR MODELING OF
    THE OCEANS IN THE ECMWF… AND ITS OVERALL BETTER PERFORMANCE AT
    LONGER RANGES…ALSO THAT HPC PREFERS THE ECMWF AND HAS FOR SEVERAL
    DAYS. AND THAT THE ENSEMBLES OF THE GFS LIKE THE ECMWF MORE WESTERN
    TRACK THAN THE OPERATIONAL GFS…TELLS ME THAT THE ECMWF SOLUTION IS
    THE ONE TO FOLLOW. STILL IT IS A LOW CONFIDENCE FORECAST. I DO WANT
    TO POINT THE THE SEA LEVEL PRESSURE…. THE 1000 MB….925 MB AND
    850 MB HEIGHTS FROM SAT THROUGH TUE FOR THAT SYSTEM ARE MORE THAN 6
    STANDARD DEVIATIONS FROM NORMAL. HAVING ANY METEOROLOGICAL QUANTITY
    6 STANDARD DEVIATIONS FROM NORMAL IS A VERY RARE EVENT INDEED. THIS
    ALSO TELLS ME THIS IS A SYSTEM WE VERY MUCH NEED TO BE WATCHING.

      That certainly sounds ominous!! Here’s hoping its being “overplayed”

    IF the Euro is correct, it would truly be a historic storm for the northeast US.

      Lol, now there’s something COMPLETELY different. It’s actually not fully absorbing Sandy’s circulation into the polar trough, but it’s amplifying the polar trough over the lower Great Lakes, and it closes the trough off into a low and strengthens it. It pulls in a tongue of Sandy’s moisture and wraps it around the circulation and back into Michigan as the low pressure system retrogrades from New York state westward into Ontario. If this situation were to happen exactly as described, the precipitation in Michigan could start off as snow or a mixture, then transition to rain on Halloween as a WARM FRONT comes in FROM THE NORTH!
