An impressive, record breaking storm system continues to impact the Upper Midwest, Great Lakes and Ohio Valley region as I type this blog. Blizzard warnings, heavy snowfall, very strong winds (thunderstorm and non-thunderstorm), severe thunderstorms and tornadoes have impacted nearly 1/2 of the CONUS over the last 24 hours. ~ CS
Here is a look at the pressures, frontal positions and selected METARS as of late this afternoon:
