KDKA Pittsburg posted an article yesterday about January’s Polar Vortex. The Polar Vortex was a very intense cold snap that began January 26th and lasted until February 1st.
Forbes Magazine reported on February 3rd:
Temperatures in the -20°Fs to -40°Fs were common from North Dakota to Illinois. A possible state record of -38°F was observed at Mount Carroll, Illinois. What was truly remarkable was the wind that accompanied these low temperatures. Many instances of sustained winds over 20 mph with temperatures colder than -20°F were reported. This causes the wind chill to drop dangerously low. For reference, a temperature of -20°F with a sustained wind of 20 mph produces a wind chill of -48°F. This is a good time to note that this analysis exclusively uses the wind chill formula developed in 2001. Based on the 2001 formula, the lowest wind chill reading I can find anywhere in any year at an official station is -73°F at Pembina, ND, in January 1936. Other lower readings probably exist, but that is the lowest I have seen.
A Virginia Tech research experiment shows that the Polar Vortex may have killed as many as 95 percent of stink bugs that hadn’t found warm shelter during the winter months.
The National Pest Management Association also says that the Emerald ash borer and southern pine beetles also likely dind’t survive the polar plunge.
Unfortunately that doesn’t mean all annoying insects were killed off in big numbers due to the frigid temperatures.
Researchers say cockroaches, and bed bugs will not be affected. Even if the adults freeze, they have already laid eggs which will hatch when the warmer weather gets here.
You may not see mosquitoes and termites this time of year, but that doesn’t mean the cold temperatures killed them off.
At least there should be some benefit to the incredibly cold weather we suffered through last month.
