Super March snow

Love ’em or hate ’em we have to acknowledge that spring snowstorms are critically important for our water supply. Most of the water that comes out of your tap is the result of snow melt, not localized rainfall.

March has been generous to us for snow, especially the March 13-15 Blizzard.

We’re well set up for a decent summer now with ample snowpack over the state.

Tragedy in Texas

Now as we are seeing deaths from tornadoes as severe weather season begins in the U.S. the cost in human life of the February storms in Texas is becoming more clear.

On Thursday Texas officials revealed that at least 111 people died in the cold, ice, and snow of the February storms. This is a higher death toll than the 68 lives lost from Hurricane Harvey.

Most of the victims died as a result of hypothermia, including an 11-year old boy who froze to death in his family’s bed in the Houston area as temperatures dropped to record lows. Others died from vehicle accidents, medical equipment failures, chronic illnesses that were suddenly worsened, a lack of home oxygen, falls, and fire, state officials said. Others died of carbon monoxide poisoning, in some cases as they tried to heat their homes.

Some of the deaths took place as early as Feb. 11; others died as a result of their illnesses and injuries as recently as March 5.

The disruptions to infrastructure, most-notably including the power grid, will be investigation and maybe litigated in the months and years to come. These types of cases are when forensic consulting meteorologists are retained as expert witnesses to determine the scope of the deadly weather and the degree to which it could (or should) have been anticipated.

Super-cool new research

Everyone wants better snow accumulation forecasts and new research from the DOE’s Brookhaven lab may be an incredible breakthrough.

Researchers have identified that drizzle drops that are “super-cooled” (between 32°F and 14°F) which come into contact with ice particles, freeze, then EXPLODE creating 10 to 1000 times more ice particles which in turn touch other drizzle drops repeating the process in a cascade.

This knowledge will help weather models to more accurately forecast the amount of ice within clouds, so the amount of snow coming from those clouds will be known much more accurately.

Now that’s “Super-Cool”!
