BlizzardWx Posted January 21, 2012 Share Posted January 21, 2012 Finally getting some rain here, .30 on the day and adding up fast. Its currently 38 at my place. Radar looks good for a few hours of rain and hopefully snow once the front makes it through. Link to comment Share on other sites More sharing options...

usedtobe Posted January 22, 2012 Author Share Posted January 22, 2012 7 day acccumullated precipation....a small area with over 20 inches along the OR/CA border Link to comment Share on other sites More sharing options...
baroclinic_instability Posted January 23, 2012 Share Posted January 23, 2012 Nice improvement on the snowpack across the Sierra after the week of storms. Wet and high elevation, but that is a good base. The latest snow currently falling with this final system is much colder with lower snow levels and better ratios. Looks like they will have to hold out for a while again as the Siberian Block breaks down and the Pacific storm tracks shifts north again. SNow shots from Mammoth Ski and Heavenly.

baroclinic_instability Posted January 23, 2012 Share Posted January 23, 2012 Good article. Lots of places in the sierra and coastal ranges got 4 to 7 inches of precip in the last 24 hrs. The heaviest I saw was over 7. When the precip is finally in a graphical form I'll post it. http://www.wrh.noaa....cnrfc&version=0 Cool thanks for the link. Is the image below some sort of MOSAIC radar accumulated estimation? Link to comment Share on other sites More sharing options...
usedtobe Posted January 24, 2012 Author Share Posted January 24, 2012 Cool thanks for the link. Is the image below some sort of MOSAIC radar accumulated estimation? I was going to link you to the site but right now it is down. The data I think is a mosaic of the precipitation from the RFCs and in the west I think it uses mountain mapper to estimate the precipitation as higher levels based on climo relationships to observed stations farther down the mountains. I think in the west they also use snotel obs which are based on the wieght of the snow. When the site comes back up, I'll post the link. Link to comment Share on other sites More sharing options...
usedtobe Posted January 24, 2012 Author Share Posted January 24, 2012 Here's the website. http://water.weather.gov/precip/ Below I've also posted a 14 day precip analysis. It is impressive across the west. Link to comment Share on other sites More sharing options...
Srain Posted March 12, 2012 Share Posted March 12, 2012 Time to revive this thread. Some very impressive totals are suggested by guidance and should they verify, rains for the lower elevations and snowfall totals for the Cascade/Sierra Range will be most impressive... PRELIMINARY EXTENDED FORECAST DISCUSSION NWS HYDROMETEOROLOGICAL PREDICTION CENTER CAMP SPRINGS MD 427 AM EDT MON MAR 12 2012 VALID 12Z FRI MAR 16 2012 - 12Z MON MAR 19 2012 A HIGH AMPLITUDE PATTERN CONTINUES TO BE ADVERTISED THROUGHOUT THE MEDIUM RANGE PERIOD...

THIS IS WHERE THE OPERATIONAL ECMWF AND ECMWF/GEFS MEANS FCST 5 TO 6 INCH QPF OVER THE FIVE DAYS AND THESE NUMBERS COULD BE MODEST. Link to comment Share on other sites More sharing options...
