Episode narrativeepisode_narrativeA large dome of high pressure that was centered across the mid section of the nation the week of July 18th, caused temperatures to rise into the 80s and 90s across the state. These temperatures combined with very high dew points in the mid to upper 70s, created heat indices between 100-115 degrees during the afternoon of Wednesday, July 20th, and into Friday afternoon, July 22nd over portions of central and southern Minnesota. ||The highest heat indices were initially across west central and into parts of east central Minnesota on Wednesday, July 20th. This is where a frontal boundary allowed for dew points to pool and led to heat indices above 105 degrees for several hours. ||As the front sagged southward, the pooled dew points and associated higher heat indices also sagged southward across southern Minnesota. Along the Iowa border, initially heat indices were much lower on Wednesday, but by Friday, these heat indices rose above 105 degrees as the front sagged to the south. ||The highest heat indices occurred between 12 noon and 7 pm. However, even the overnight temperatures only fell into the upper 70s to lower 80s, creating dangerous readings for those who did not have air conditioning or were caught out in the elements. ||The following are recorded highest heat indices in this three day period;||Near Savage 120 F |Near Eagan 118 F|Near Lake City 118 F |Faribault 117 F |Near Bloomington 117 F |New Prague 116 F |Near Inver Grove Heights 116 F |East of Jordan 116 F |St. Paul 116 F |Farmington 115 F |Redwood Falls 115 F|Madelia 114 F|South of Red Wing 114 F|Minnesota Lake 114 F |Morton 114 F|Lakeville 113 F|Morristown 113 F|West of Clara City 113 F.
Event narrativeevent_narrativeSeveral surface observations across Steele County measured heat indices over 105 degrees for several hours during the afternoon of Thursday, July 21th, and again Friday afternoon July 22nd. Temperatures only managed to fall into the mid to upper 70s during the morning of July 22nd, and rebounded into the 80s and 90s once again by the afternoon.
