Since February 3rd, Estherville (NW Iowa) has been below freezing. This makes for an eighteen day plus stretch of hourly temperatures below 32 degrees. The featured chart shows the longest such stretches during the month of February for the site. Note that the period of record only goes back to 1987. The current forecast has a chance of breaching 32 degrees either today or on Saturday, but after the upcoming powerhouse storm the temperatures return to well below freezing again for another extended stretch.
