July Pressure Records

09 Jul 2018 05:38 AM
Iowa's weather this past weekend was spectacular with plenty of sunshine and light winds along with reasonable humidity and temperature levels. This weather was thanks to an expansive high pressure system the covered much of the continental US. This system was rather remarkable for its size and strength. A number of July maximum pressure observations were recorded over the Midwestern US. The featured chart shows the hourly pressure maximums for the Mason City Airport weather station based on IEM archives. Friday's values were records for most hours and eclipsed the previous high maximum set back in 1997.
