Here was the view from Canal Park in downtown Duluth early Saturday morning (Grandma's Marathon Race Day). Although the view looks pretty, warm conditions are expected for the day, which could make for a little tougher go for runners. Most of the race should be rain/storm free, but afternoon/evening activities could contend with scattered showers and storms.
"Grandma's Marathon Runners Prepare to Beat the Heat"
Here's a story about the warmth expected for Grandma's Marathon this year from a TV news station that I worked at in Duluth for 2 years.
"Duluth, MN (NNCNOW.com) -- Running a marathon requires lots of preparation from training to diet. But one thing runners are unable to prepare for is the heat."

Wild Storms on Friday
Take a look at the storm report map from late Thurdsay night through Friday night. Interestingly, a line of storms started in western North Dakota on Thursday night and moved through Bismarck, ND with up to 3.25" diameter hail. It then moved into NW Minnesota with up to 80mph before dropping almost straight south into SW Minnesota with a number of large hail and damaging wind reports through the rest of the day Friday. Other than a few light rain showers, the Twin Cities didn't see much of anything.
All of the water vapor in the atmosphere served as fuel for thunderstorms, which became widespread across the state over June 11-14. Over those 4 days many areas received from 2-4 inches of rain. A few highly localized amounts were even greater causing some short-lived flooding concerns. You can read more about the distribution of these storms at the Minnesota StateClimatology Office web site.
The strong thunderstorms on June 14th produced tornadoes in Pipestone, Traverse, Big Stone, Le Sueur, and Blue Earth Counties. All were relatively short-lived and produced relatively little damage. Very strong winds up to 60mph were also reported from portions of Nobles, Jackson, Cottonwood, Brown, and Watonwan Counties.
As a result of the rainy week, many climate stations are already reporting total monthly rainfall that exceeds the June normal. This continues a recent climate trend for June, as 15 of the most recent Junes have been normal or wetter than normal on a statewide basis.
Severe Threat Saturday
...SUMMARY... THUNDERSTORMS CAPABLE OF PRODUCING LARGE HAIL AND STRONG WIND GUSTS ARE POSSIBLE LATE THIS AFTERNOON INTO TONIGHT FROM NORTHERN MONTANA ACROSS NORTH DAKOTA INTO ACROSS PARTS OF NORTHERN MINNESOTA. VERY LARGE HAIL WILL BE POSSIBLE ACROSS PARTS OF NORTHERN MONTANA. A FEW MARGINALLY SEVERE STORMS WITH STRONG WIND GUSTS MAY OCCUR ACROSS SOUTHERN MISSISSIPPI AND LOUISIANA THIS AFTERNOON.
Severe Threat Sunday
...SUMMARY... SCATTERED SEVERE STORMS ARE POSSIBLE SUNDAY FROM EASTERN SOUTH DAKOTA ACROSS MUCH OF MINNESOTA AND INTO NORTHWEST WISCONSIN WITH HAIL AND WIND EXPECTED.
Excessive Heat Building in the Southwest
The dome of hot weather will continue to build across the Southwestern part of the nation with some spots nearing all-time record highs Sunday and Monday.
Excessive Heat Watches and Warnings
The National Weather Service has issued a number of excessive heat watches and warnings across the Southwest, which includes major cities like Los Angeles, Las Vegas, Phoenix, Tucson and Yuma.
Potential High Temperatures & Stats
- Highs will approach 120 on both Sunday and Monday. Phoenix has only had a high of 120 or higher three times in their recorded history (since 1895).
- The last time Phoenix hit 120 or higher was back on July 28, 1995 when the thermometer hit 121.
- Whether the temperature touches 120 or not, record highs are likely. The current record high each day between Saturday and Tuesday is 115.
- We are calling for a forecast high of 114 on Sunday. Only seven times in Tucson recorded history (since 1894) has the city seen a high of 114 or higher – the last time occurring on July 28, 1995 when it also reached 114.
- The all-time record in Tucson history is 117 set back on June 26, 1990.
- Record highs over the weekend and into next week are 113 Saturday, 112 Sunday, 110 Monday and 112 Tuesday.
Las Vegas, NV
- Las Vegas is no stranger this type of higher heat in the forecast, reaching a temperature of 115 or higher 55 times since 1937. The last time Las Vegas saw a high of 115 or higher was back on July 2, 2013.
- The warmest high ever in Las Vegas history is 117 reached three times in their history. The most recent occurrence was back on June 30, 2013.
- Our forecast has Las Vegas reaching 114 both Monday and Tuesday next week.
- Record highs this weekend into next week are 115 Saturday, 114 Sunday, 113 Monday and 111 Tuesday.
Los Angeles, CA
- Even Los Angeles will get in on the heat this week into early next week, reaching at least the mid 90s Sunday through Tuesday.
- We could even see highs in downtown Los Angeles break the triple-digit mark next Monday. Down toward LAX, highs Monday will be near 90, which could break the record for the day of 86.

Grandma's Marathon - Hot and Sticky for Dad's Day
By Todd Nelson, filling in for Douglas.
Having lived in Duluth for four years, I have very fond memories of Grandma's Marathon weekend. There's something to be said about the camaraderie of fellow runners all striving for the same goal, to finish a grueling 26.2 mile run! As a finisher of the Grandma's half-marathon twice and full marathon once, I give runners and fans a lot of credit for their dedication. Good luck today!
Somewhat unsettled weather takes us into the last weekend of Spring 2016 as the summer solstice arrives on Monday at 5:34pm CDT. With that said, it'll feel very much like summer this Father's Day weekend with high temps on Sunday warming into the 90s and tropical dewpoints nearing 70 degrees. It'll be a sweat box for sure, hope you can find some A/C!
Scattered showers and storms will have no problem developing on the northern periphery of this hot dome through the weekend, so have a plan 'B' if skies look threatening. A few strong storms fire in northern MN on Saturday, while most of the state sees an increasing strong thunder risk late Sunday.
SATURDAY: Feels like summer. Partly to mostly cloudy with more storms N. Winds: SSW 5-10. High: 86
SATURDAY NIGHT: Partly cloudy with a few stray storms. Winds: S 5. Low: 68
SUNDAY: Hot & sticky Father's Day. Heavy storms late evening (some severe?). Winds: SSW 10-20. Wake-up: 68. High: 92
MONDAY: Summer begins. Less muggy, stray storm. Winds: WNW 10-20. Wake-up: 62. High: 80
TUESDAY: Beautiful! Low humidity and bright sun. Winds: NW 5-10. Wake-up: 59. High: 76
WEDNESDAY: Few clouds, fresh breeze. Winds: NNE 5. Wake-up: 57. High: 76
THURSDAY: A touch warmer. Still mostly dry. Winds: SW 5. Wake-up: 60. High: 80.
FRIDAY: Humidity returns. Spotty PM thunder? Winds: S 5-15. Wake-up: 60. High: 80
This Day in Weather History
1939: A deadly tornado hits Anoka. 9 fatalities and over 200 injuries are reported.
1850: Territorial Governor Ramsey reports that about halfway between Ft. Ripley and Ft. Snelling on the Mississippi a severe hail storm occurred in the evening. One or two hailstones picked up were as large as hen’s eggs and he thought he saw one about the size of a 'musket ball.'
Average High/Low for Minneapolis
Average High: 80F (Record: 98F set in 1953)
Average Low: 60F (Record: 39F set in 1876)
Sunrise/Sunset Times for Minneapolis
*Daylight gained since yesterday: ~11seconds
*Daylight gained since Winter Solstice (December 22nd): ~6hours and 51mins
Moon Phase for June 18th at Midnight
1.2 Days Until Full (Strawberry) Moon
More Heat on the way? Here's the extended forecast depicted from the ECMWF model, which suggests another hot front arriving on Father's Day Sunday with high temperatures getting to near 90F! However, it doesn't appear to last too long as highs much of next week look to settle into the low/mid 80s.
6 to 10 Day Temperature Outlook
According to NOAA's CPC, the 6 to 10 day temperature outlook suggests above average temperatures returning to the Midwest from June 23rd - 27th. Side note; the Summer Solstice is Monday, June 20th!
Saturday Weather Outlook
Temperatures on Saturday will be a bit warmer than they were on Friday across much of the state. Note that some mid to upper 80s will be found across the southern half of the state, while muggy dewpoints return and slide up into the 60s across much of the state.
Saturday Weather Outlook
A light southerly wind will continue across the state on Saturday with stronger winds found across the Dakotas.
Saturday Weather Outlook
Scattered showers and storms will be found across the northern half of the state on Saturday, while areas across the southern half of the appear to be quiter with more sunshine.
The simulated radar through AM Monday suggests ongoing showers and storms across the northern half of the state on Saturday with a better chance of storms across the rest of the state on Sunday. Keep in mind that some of the storms on Saturday and late Sunday evening could be strong to severe.
Rainfall potential through AM Monday suggests heavier rainfall across northern Minnesota . This heavier rainfall potential will be associated with scattered showers and storms that will be on and off through the weekend.
National Weather Outlook
A storm system moving into the Western U.S. that brought snow to parts of the northern Sierra Nevada range will wash out a bit through early weekend. As this happens, dangerous heat begins develop in the Southwest through early next week. Meanwhile, scattered showers and storms will be possible across parts of the Midwest through the early weekend.

AT THE SFC...A LOW WILL DEVELOP ACROSS CNTRL MT TODAY WITH A BROAD MOIST SECTOR LOCATED TO THE EAST OF THE LOW ACROSS THE NRN PLAINS. AS THE UPPER-LEVEL TROUGH APPROACHES THE NRN ROCKIES...CONVECTION WILL INITIATE AROUND MIDDAY AHEAD OF THE TROUGH IN THE HIGHER ELEVATIONS OF WRN MT. THIS CONVECTION WILL EXPAND IN COVERAGE AS SEVERAL CLUSTERS OF THUNDERSTORMS MOVE NEWD INTO THE LOWER ELEVATIONS OF THE NRN HIGH PLAINS WHERE MODERATE INSTABILITY IS FORECAST THIS AFTERNOON. OTHER THUNDERSTORMS MAY POSSIBLY DEVELOP FURTHER EAST DURING THE AFTERNOON ACROSS ND OR NW MN ALONG THE NRN EDGE OF MODERATE INSTABILITY. A LOW-LEVEL JET WILL STRENGTHEN ACROSS THE REGION DURING THE MID TO LATE EVENING WHICH WILL SUPPORT AN MCS MOVING EWD ACROSS PARTS OF SRN CANADA AND POSSIBLY NRN ND. THE MCS MAY REACH PARTS OF THE UPPER MS VALLEY LATE IN THE PERIOD. A SEVERE THREAT IS LIKELY THIS AFTERNOON AND EVENING FROM THE SFC LOW EWD ALONG THE TRACK OF THE MCS WHERE MODERATE INSTABILITY WILL BE IN PLACE. FORECAST SOUNDINGS JUST TO THE EAST OF THE SFC LOW ACROSS NERN MT LATE THIS AFTERNOON SHOW MID 60S F SFC DEWPOINTS...MLCAPE OF 2000 TO 2500 J/KG...0-6 KM SHEAR NEAR 60 KT AND 700 TO 500 MB LAPSE RATES OF 8.0 C/KM. THIS ENVIRONMENT WILL SUPPORT SUPERCELLS WITH LARGE HAIL AND WIND DAMAGE. HAILSTONES OF GREATER THAN 2 INCHES IN DIAMETER WILL BE POSSIBLE WITH THE MORE DOMINANT SUPERCELLS. LOW-LEVEL SHEAR IN NRN MT IS ALSO FORECAST TO BE ADEQUATE FOR TORNADOES LATE THIS AFTERNOON. ISOLATED SUPERCELLS WITH LARGE HAIL MAY ALSO DEVELOP FURTHER TO THE EAST ACROSS NRN ND WHERE MODERATE INSTABILITY AND STRONG DEEP-LAYER SHEAR IS FORECAST. A FAST MOVING LINEAR MCS WITH A WIND DAMAGE THREAT SHOULD ORGANIZE AND MOVE ACROSS SRN CANADA THIS EVENING INTO TONIGHT. DAMAGING WIND GUSTS ASSOCIATED WITH THE SRN PART OF THE SEVERE MCS MAY AFFECT PARTS OF NRN ND AND NW MN. ...LOWER MS VALLEY... AN UPPER-LEVEL TROUGH WILL MOVE SWD ACROSS THE GULF COAST REGION TODAY AS A COLD FRONT ADVANCES SWD INTO THE LOWER MS VALLEY.

5 Day Rainfall Potential
According to NOAA'S WPC, the 5 day rainfall forecast suggests heavier pockets of rain across parts of the northern tier of the nation through the Mid-Atlantic states and into the Southeastern U.S.. Keep in mind that with thunderstorm activity, some locations could see 1" to 2"+ through the end of the weekend.
Global temperature records were broken yet again in May 2016, according to data just released by NASA, and the US National Oceanic and Atmospheric Administration, which also reported that it was the hottest (northern hemisphere) spring on record. The year to date is also the hottest on record. NOAA reported that the atmospheric concentration of carbon dioxide, which is driving global warming, passed 400 parts per million on 23 May at the South Pole – the last place on earth to breach the milestone.
After five consecutive record months it comes to no surprise that the average global land and ocean surface temperature for January–May 2016 resulted in the warmest such period on record across the world's land and ocean surfaces, at 1.08°C (1.94°F) above the 20th century average of 13.1°C (55.5°F), surpassing the previous record set in 2015 by 0.24°C (0.43°F), according to NOAA
The heat has been especially pronounced in the Arctic, resulting in a very early onset of the annual melting of Arctic sea ice and the Greenland ice sheet. Snow cover in the northern hemisphere was exceptionally low.
“The rapid changes in the Arctic are of particular concern. What happens in the Arctic affects the rest of the globe. The question is will the rate of change continue? Will it accelerate? We are in uncharted territory.”
Race to save hidden treasures under threat from climate change
Thousands of ancient treasures that have been unearthed by climate change could soon be lost to humankind forever, as they are eroded by weathering and eaten by pests. The crisis is so extreme that some archaeologists are urging colleagues to abandon their current field sites and focus instead on these newly exposed relics before they vanish. Rising seas, raging storms, melting ice and forest fires are revealing artefacts that have much to tell us about our history on Earth – from sunken shipwrecks in Svalbard to the ancient waste dumps filled with bones, shoes and carvings emerging all over the Arctic and further south, including in Scotland. “This material is like the library of Alexandria. It is incredibly valuable and it’s on fire now,” George Hambrecht, an anthropologist at the University of Maryland, College Park, told New Scientist at the Anthropology, Weather and Climate Change conference held in London last month.
