FRIDAY EVENING UPDATE (2/16/2024)—QUITE A FRIDAY SNOW IN DOWNSTATE ILLINOIS AND INDIANA

  • The heaviest tallies 6″ and greater accumulations: downstate in corridor from St. Louis and Springfield, IL across to Decatur and Champaign across through the Indianapolis area.
  • The snow was the product of a CLIPPER-LIKE SYSTEM which raced out of the Plains and heads toward the East Coast Friday evening.

FRIDAY’S EASTBOUND MIDWEST SNOW SYSTEM

  • Here’s a look at Friday’s eastbound midwest snow system expected to race to the east coast during the day and Friday night
  • VISIBILITIES offer an insight into where snow is falling since snow reduces horizontal visibility. A plot of Friday morning visibilities is included among the graphics I’ve posted below.


THE LATEST CALIFORNIA-NEVADA DROUGHT UPDATE IS IN

  • Much attention has been paid over the years to the moisture situation in the West—an area ravaged for many years by mega-drought conditions—yet in the news when on the receiving end of ATMOSPHERIC RIVER storms with their copious precip.
  • There is nothing fixed about moisture availability in the West. The situation will vary year to year—so the region’s moisture situation is and will continue a “moving target” —and given the population which moisture levels must support, one of great and ongoing interest.
  • Water availability has always been a challenge, especially in the Inter-mountain West and desert Southwest which has undergone such dramatic growth yet has access to a finite supply of water which, given the growth in the region, has water resources which are overcommitted.

REGULAR UPDATES on MOISTURE SUPPLIES ARE OFFERED BY NOAA—and the most recent on February 15, 2024 makes the following points:

Key Points in the latest report:

  • A warmer, drier start to the water year was at first buffered by carryover (e.g., soil moisture, reservoir storage) from the wetter-than-normal Water Year 2023.
  • More recently, atmospheric river events alleviated water year precipitation deficits throughout parts of the region. The February 4–7 event brought 20% to over 40% of water year normal precipitation for parts of southern California.
  • Snow drought conditions are improving, but the Sierra Nevada snowpack remains below normal.
  • This ongoing wet pattern is expected to continue over the coming days and weeks. Temperatures will be key in determining the extent of snowpack building and snowmelt rates going into spring and summer.
