1964: Earliest official measurable snowfall in Minnesota with 0.3 inches at International Falls.
1952: Early frost hits Ft. Snelling and ends the growing season.
I would surmise that Minnesota's weather has always been...odd. Jaw-dropping at times. Remember, the most extreme weather is routinely found near the center of continents, well away from moderating influences of mild ocean water.
Rory Groves at Swift Weather was incredulous with the recent frost (2-3 weeks ahead of schedule for many towns). "Much has been written about warming, but what causes cooling? Is this just a sun-cycle thing? I don’t recall anything like it in 30 years" he wrote.
We're seeing more volatility in the weather system, more extremes in general from a higher amplitude jet stream pattern. The arctic is warming twice as fast as Minnesota, and this may be impacting the configuration and stability of the jet stream. The truth: we're in uncharted waters.
No frost in the extended outlook, in fact there's a chance you may be complaining about the humidity by late week as temperatures climb toward 80F. Long-range models hint at 70s and a few 80s into late September.
Dry weather lingers for the next 5 days, a few late-week T-showers. No snow, ice, earthquakes, sandstorms or volcanic eruptions either.
The September you've been waiting for is still on the way.
- Persisting and intensifying drought in parts of the West: Despite beneficial precipitation in parts of the drought-stricken West during August, long-term drought conditions will continue to impact water resources and agriculture and increase wildfire risk. More information is available from the U.S. Drought Monitor.
- El Niño still probable later this year: According to NOAA's Climate Prediction Center, there is a 60-65 percent chance of at least a weak El Niño developing this upcoming autumn or winter. El Niño conditions could have impacts on temperature and precipitation patterns across the U.S. More information is available from the Climate Prediction Center.
There Are Seven Riskier Places To Live Than In Oklahoma. Tornadoes get a lot of well-deserved airtime, but when it comes to overall risk Florida still tops the list. A few of the Top 5 states were surprising. Here's an excerpt from a story at newsok.com: "...CoreLogic ranked Florida as the state with the highest level of exposure due to multiple natural hazards — Florida has it all. “Florida’s high level of risk is driven by the potential for hurricane winds and storm surge damage along its extensive Atlantic and Gulf coastline, as well as the added potential for sinkholes, flooding and wildfires,” said Dr. Howard Botts, vice president and chief scientist for CoreLogic Spatial Solutions. Michigan was ranked last. The Rust Belt gets a break..."
