The general flow pattern over the Northern Plains was very weak. However, by mid afternoon on the 11th, a few thunderstorms flared up along a line from Hillsboro (ND) to Erskine (MN). As these storms died off they sent out numerous outflow boundaries that showed up very well on radar. Two of these outflow boundaries intersected just southwest of Grand Forks, causing another thunderstorm cell to flare up. This storm moved across the southern edge of the city of Grand Forks, producing some large hail and localized gusty winds.

Low pressure was located over northwestern Iowa with a warm front well north into Michigan. The main upper level jet energy remained west of the area. The environment consisted of strong instability, with surface based CAPE in excess of 500 j/kg and low shear. Storms struggled initially with isolated reports of hail or wind damage. As the storms congealed, larger segments of storms took shape, causing more widespread wind damage.

This interaction sparked another round of thunderstorms in the unstable air mass during the afternoon, resulting in isolated damaging winds.

An upper level low pressure system along the California coast spread moisture into southeast California, and this led to the development of isolated thunderstorms over Imperial and Riverside counties on the 12th.

Thunderstorms with strong, damaging winds moved through the Desert Center area during the morning hours on September 13th. Fire Department personnel reported that a 20 by 40 foot patio cover at the fire station was ripped by strong winds. The winds, estimated to be in excess of 50 knots, also knocked down several palm fronds. The fire station was located just to the northeast of the Desert Center airport.
Despite very limited reports of severe weather, thunderstorms were quite numerous across South Central Nebraska from the early evening hours of Sunday the 7th into the morning hours of Monday the 8th, with the greatest coverage focused overnight. The first strong to severe multicell storm of the event tracked nearly due east near the Interstate 80 corridor during the evening, first entering western Dawson County around 7 PM CDT, and weakening considerably by 930 PM CDT along the York-Polk County line. The only severe-criteria report along the way consisted of 60 MPH winds near Gothenburg, though gusts neared 50 MPH at the Grand Island airport. During the late evening hours, northern portions of the area narrowly missed being impacted by a fast-moving bow echo mesoscale convective system that produced damaging winds across parts of north central and northeast Nebraska. Overnight, storm coverage within South Central Nebraska increased markedly, as multiple rounds of mainly multicell clusters flared up and passed from west to east across the area. Although no severe-criteria reports were received late in the night, nickel size hail was reported in Superior, and the Hastings airport measured gusts to 51 MPH. In the end, locally heavy rainfall ended up being the main story with the overnight storms, with parts of primarily Adams, Clay, Nuckolls and Thayer Counties tallying at least 1-2 inches.
These evening and overnight storms were just one chapter of several days of active weather within the Central Plains region, as multiple weak disturbances rippled through seasonably strong quasi-zonal flow aloft. With the main core of upper level winds directly overhead, deep-layer vertical wind shear was quite strong for early August, averaging between 40-50 knots. The increased coverage of overnight storms was largely attributed to enhanced convergence along the nose of a modest 30 knot low-level jet evident at 850 millibars.

A very moist and unstable airmass was in place over Iowa during the late afternoon and evening of the 23rd.  Surface temperatures warmed into the 90s, with dewpoint readings in the mid 70s to around 80.  CAPE rose to between 5000 and 7000 J/kg with a lifted index of -5 to -9 C.  Monsoonal flow was in place across the state with precipitable water values around 2 inches.  The freezing level remained very high, in the 15,500 to 16,000 foot range.  An outflow boundary was in place across southern Iowa due to convection that had taken place during the day on the 23rd.  Thunderstorms erupted during the early evening hours along the outflow boundary.  Downdraft CAPE values were quite high, in the 1500 to 2000 J/kg range.  The atmosphere was weakly sheared with 30 to 35 kts of shear available.  There was little hail associated with the storms as the freezing level was very high.  Winds of 60 MPH or more were reported with the storms with scattered tree and power line damage.  A tin roof was partially torn off in Appanoose County.  High winds bent corn over in Lucas County.  These were two of the stronger wind gusts.  Heavy rain also occurred with the storms.  Three inches of rain fell in an hour east of Chariton in Lucas County.
