We Still Can't Predict Snow Down To The Inch
"Paul, there's a big discrepancy between your weather app and what you're publicly predicting at Conservation Minnesota. What's going on?" Welcome to my world.
Apps are great, but they don't capture all the nuance, variation or challenges with a specific forecast. That's where the human element comes in: meteorologists add value by adding context, perspective and analysis.
Not even Siri can do that. Yet.
My favorite college professor told us to "forget about inches" and classify storms into 3 categories: nuisance, "plowable" and crippling. I've been borrowing the scale since 1983 at KARE-11. It has stood the test of time.
Yesterday's hail-producing T-storms are long gone; cold exhaust on the backside of the storm sparks a wintry mix into Thursday - a nuisance coating is possible. The coldest air of the season arrives late next week with highs in the 20s.
That's 20s ABOVE zero.
Some moderation is likely by mid-December as winds blow from the Pacific, not the Arctic.
Any big, meaty storms pass south of Minnesota into next week, but I'm bullish on a white Christmas this year. We are due.
Unusual For November 28. Midday Doppler radar from the Twin Cities Chanhassen office showed a line of strong T-storms pushing across the metro with numerous reports of pea-size (.50") hail, depicted in yellow on the map above.

Many 500-Year or 1,000-Year Floods Reported This Year. Here's a nugget from a story at Weather or Not and CDAPress.com: "It’s almost hard to believe, but areas that are currently reporting major drought conditions experienced massive flooding earlier this year. Normally, we see these huge 500-year or 1,000-year flood events less than once per year. For 2016, there have been nearly a dozen events, which indicates that our cycle of Wide Weather “Extremes” is still going strong with no signs of letting up anytime soon. Most of the big flood events were east of the Rockies. In early June, Houston reported 22 inches of rain, which was a 500-year event. Dallas picked up 16 inches of rain, also a 500-year flood..."

On Virginia's Vulnerable Coast, Fear of Flooding On The Rise. The Norfolk/Tidewater region of Virginia is nearly as vulnerable to rising seas as south Florida. ABC News reports: "...Experts warn that flooding will likely increase in Virginia's Hampton Roads region, where Virginia Beach and six other cities are clustered on or near the state's low-lying coast. The land is sinking and the sea is rising at the highest rate on the East Coast, they say. Global warming threatens to draw more intense rain storms up the Eastern Seaboard. Fears are growing that this historically prime location for military installations threatens livelihoods as much as it sustains them. The Atlantic meets the mouth of the Chesapeake Bay here along with the confluence of three rivers. The world's largest naval base sits in Norfolk, nearby. A commercial port, ship builders and a railroad help fuel the economy..." (File image credit here).

Another U.S. City Commits To 100% Renewable Energy. Details via Solar Industry: "The St. Petersburg, Fla., City Council has formally approved the city’s commitment to transition to 100% clean, renewable energy. According to the Sierra Club, St. Petersburg represents the first city in Florida and the 20th city in the U.S. to make such a commitment. In a unanimous vote, the City Council Committee of the Whole has allocated $250,000 of BP settlement funds from the 2010 Deepwater Horizon oil spill to an Integrated Sustainability Action Plan (ISAP), which will chart a roadmap to 100% renewable energy in St. Petersburg..."
Why Planting More Trees Is One Of The Smartest Things a City Can Do. Why? Here's an excerpt from Vox: "...Trees can make a city sidewalk prettier, sure. But that’s not even their best trick. A growing pile of research suggests that planting more urban trees, if done right, could save tens of thousands of lives around the world each year — by soaking up pollution and cooling down deadly heat waves. In fact, as a fascinating new report from the Nature Conservancy details, a well-targeted tree campaign could be of the smartest investments a hot, polluted city can make. Which seems important, given that the world’s cities will add about 2 billion people this century, and they’re only getting hotter..."
