Though parts of the country have already seen snow this fall — fueling speculation it’s going to be a long, snowy winter — the latest forecast shows that while morning temperatures have been cooler than normal in the Midwest, a warmup is on the way, with above-normal temperatures canvassing the country from west to east by later this week. Meteorologists are watching the re-establishment of record-low polar ice as an indicator of the potential for polar vortex-driven extreme weather later this year and into 2021. The weather looks good for fall fieldwork in much of the nation until a system begins to move in and fuel potentially volatile weather in the center of the nation this weekend and into next week.
