This week started off with record high temperatures and wildfire threat, but has finished with a major snow storm. The featured map presents a current analysis of available NWS and CoCoRaHS snowfall reports with amounts well over a foot reported within a stripe across Northeastern Iowa. There was sleet with this event as well, so liquid equivalent amounts were high and much needed to help with the ongoing drought. This snow will stick around for a few days, but above freezing temperatures are expected next week and then warmer weather to start off March. This map will be updated later today as more reports come in.
