Thanks to Rich Koivisto for the image below. Looks like the resident hummingbird is enjoying a quick rest and a sweet treat!



Soggy Outlook Ahead
Take a look at the weather outlook through PM Thursday and note the significant push of moisture across the West Coast. This first big push of moisture will be the first of two through the end of the week.



Precipitation Potential
According to NOAA HPC, the 5 day precipitation forecast looks exceptionally juicy over California through the end of the weekend. In some cases, precipitation amounts could near 3″ to 6″ or more! Unfortunately, the ground is like concrete from being so dry for so long. There is a substantial flooding risk as runoff could be a major concern.



Western Warns
The National Weather Service  has issued a number of Winter Weather Headlines from the Sierra Nevada Mountains to the San Bernadino Mountains. Significant accumulations of snow may be possible by the time these two storm systems blow through.

Here’s more information from the National Weather Service out of Los Angeles/Oxnard, CA about the storm coming later this week:

Two storm systems are on track to impact southwestern California Wednesday through Saturday The first storm is expected to move across the area Wednesday afternoon through Thursday, bringing light to moderate rainfall to the area with about one half to one inch of rain for most locations and a few inches of snow accumulation above 7000 feet. From late Thursday night through late Saturday night, a second and much stronger system will affect the region with significant rainfall, heavy snow in the high mountain elevations, strong and gusty winds at times over higher terrain, scattered thunderstorms, and the threat of mud and debris flows in and below recent burn areas. One and a half to two and a half inches of rainfall is likely in coastal and valley areas, and two to four inches is likely in the foothills and mountains. Due to strong southerly flow ahead of the storm, locally higher amounts up to six inches are possible in favored upslope areas in the local mountains. Snow levels will remain high on Friday morning at above 7500 feet, but will drop to between 5500 and 6000 feet by Friday night, then drop further to 5000 to 5500 feet on Saturday. Snow accumulations of up to 1 to 2 feet will be possible mainly above 7000 feet. Winter storm conditions can be expected in the higher mountain elevations due to heavy snowfall and gusty winds. Additionally, this storm will be rather dynamic and thunderstorms may develop which could produce intense short-duration rainfall and small hail. Communities in and around recent wildfires, especially the Colby, Madison, Powerhouse, Madre, and Springs burn areas, will need to be alert for heavy and intense rainfall which could produce mud and debris flows. Drainage areas should be cleared of debris to help reduce the chance of urban flooding. 

Significant Cold For End of February
Here’s the temperature anomaly from February 25th, which shows a large blog of much colder than average air draining down into the Lower 48.



A Look Ahead
Here’s the outlook for Thursday, which doesn’t look much better as another surge of Arctic air settles south of the international border.



Highs Thursday
High temperatures on Thursday looks significantly colder  across the Upper Mississippi Valley, while the warmth across the Southwest continues for now.



Highs From Normal Thursday
UGH!



Northern Lights Potential
The strongest flare of the year thus far erupted on the sun on Tuesday. The good news is that this particular flare will only graze the Earth! 
Radio emissions from shock waves at the leading edge of the CME suggest an expansion velocity near 2000 km/s or 4.4 million mph. If such a fast-moving cloud did strike Earth, the resulting geomagnetic storms could be severe. However, because its trajectory is so far off the sun-Earth line, the CME will deliver a no more than a glancing blow. NOAA forecasters expect a weak impact late in the day on Feb. 26th.

Giant Walls to Protect the U.S. form Tornadoes?
Now here’s an interesting take on how to control tornadoes across the United States. This story comes from USA Today

“Forget the Great Wall of China… How about the Great Wall of ….. Kansas?
One scientist thinks we can protect parts of the central USA from ferocious tornadoes by building several gigantic walls across Tornado Alley:
“If we build three east-west great walls in the American Midwest …. one in North Dakota, one along the border between Kansas and Oklahoma to the east, and the third one in south Texas and Louisiana, we will diminish the tornado threats in the Tornado Alley forever,” according to physicist Rongjia Tao of Temple University.
The walls would need to be about 1,000 feet high and 150 feet wide, he said. Tao is presenting his research next week at the annual meeting of the American Physical Society in Denver.

One response to “Arctic Plunge Intensifies and Significant Rain and Snow for California

  1. A suggestion.
    When scrolling the counties under a watch or warning (Winter Storm…); how about listing the State before the list of counties?
    I see a bunch of county names and have no clue where they are.
    Thanks!
