The episode as NWS DLH wrote it up.
Thunderstorms developed during the middle of the day on June 5th near the Duluth area. The storms produced some hail and gusty winds. Most of the hail stones were pea to penny size, but one storm dropped hail up to 1.5 in diameter and produced strong enough winds to topple some trees.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Duluth, MN wrote its last area forecast discussion before the first event at Jun 5, 9:13 AM CST, 2 hours 32 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Duluth MN 1013 AM CDT SUN JUN 5 2016 .UPDATE... Issued at 1013 AM CDT Sun Jun 5 2016 The forecast was updated through tonight, mainly focusing on the winds and pcpn chances through this evening. The latest rap, nam, and gfs soundings have widespread 20 to 30 mph within the mixing layer for this afternoon through this evening, so felt confident in the need to increase the sustained and wind gust speeds for today. The strongest winds will likely be within a corridor from the Brainerd Lakes to Pine City areas of northeast Minnesota this afternoon, where gusts could approach 30 mph. Still expecting scattered showers and isolated/scattered thunderstorms this afternoon through this evening. Increased the pcpn chances though to have some periods of likely/numerous showers during the middle to late afternoon, including for the Twin Ports and northwest Wisconsin. && .SHORT TERM...(Today through Monday) Issued at 331 AM CDT Sun Jun 5 2016 The weather pattern will be changing as the earlier stacked low is moving eastward. The early morning weather map features the longwave trough extending from central Manitoba through Lake Superior and all the way down to TX. The surface low was over Lake Huron while high pressure was over the High Plains to the TX Panhandle. with the low moving off...the extensive cloudiness has dissipated over the northland so we will see more sun today. But more clouds will develop quickly after sunrise with very steep lapse rates with a 500 mb cold pool at -16 to -20C. The effects of this combined with a strong short wave rotating through the upper trough will set off afternoon showers and thunderstorms in a weakly unstable airmass. As these will be somewhat diurnally driven expect a decrease in the evening...but with the series of shortwaves moving through the upper flow there will continue to be a chance of showers through Monday. Winds will increase today with BUFR soundings indicating a deep mixed layer with dry adiabatic lapse rates with over 25 knots available to mix down...with the highest over the southwest corner of the forecast area. BUFR sounding at KBRD shows a mixing height of 6500 feet or 750 mb where winds will be 28 kts and these could mix down to the sfc. .LONG TERM...(Monday night through Saturday) Issued at 331 AM CDT Sun Jun 5 2016 Concern for long term is chances for precipitation is low relative humidity values on Tuesday...chance for precip Thursday through Sunday. A ridge of high pressure will bring in much drier air to the forecast region on Tuesday. The soundings indicate there will be a deep mixed layer up to near 700 mb. Mixing down this down to the surface along with the higher winds will push relative humidity values into the 22-28 percent range across most of the area. These conditions may cause some fire weather concerns on Tuesday. The ridge moves east Tuesday night and Wednesday which will cause a southerly flow to develop along with warmer temperatures. A shortwave will move through the upper level ridge and travel across the region Thursday and Friday brining a possibility of showers and scattered thunderstorms for Thursday and friday. An area of low pressure will develop in the northern plains Friday night and slowly move east over the weekend. This will pull in more moisture across the region Saturday and Sunday bringing a good possibility of showers and thunderstorms for the weekend. && .AVIATION...(For the 12Z TAFS through 12Z Monday morning) Issued at 631 AM CDT Sun Jun 5 2016 fog and low ceilings are causing lifr-ifr conditions at DLH/HIB and HYR taf sites at issuance time. These conditions should improve to vfr by 14z as the winds increase. The BRD/INL sites are mvfr and should also increase to VFR by 14z. The winds will increase to nw 10-15 mph with gusts to 20-25 mph by late morning at all taf sites and continuing into the evening. There will be a possibility of showers and thunderstorms beginning midday and extending into the evening hours. The winds will decrease late evening but there will still be a possibility of a shower or thunderstorm. VFR conditions should dominate the TAF sites tonight with MVFR conditions in fog possible after midnight. && .PRELIMINARY POINT TEMPS/POPS...
