Severe Threat Saturday
...PORTIONS OF MT EWD TO NRN MN...
SHOWERS AND SCATTERED THUNDERSTORMS MAY BE ONGOING AT THE START OF
THE PERIOD OVER ERN PORTIONS OF THE RISK AREA -- I.E. PORTIONS OF
THE DAKOTAS AND MN VICINITY -- INVOF THE TRAILING/W-E PORTION OF A
CANADIAN COLD FRONT PROGGED TO HAVE SAGGED SWD INTO THE REGION.
THIS CONVECTION COULD PERSIST AND/OR INCREASE INTO THE
AFTERNOON...AS THE FRONT LINGERS AND HEATING OF THE MOIST BOUNDARY
LAYER YIELDS MODERATE DESTABILIZATION. GIVEN ENHANCED WSWLYS
ALOFT...SOME RISK FOR ISOLATED SEVERE STORMS IS APPARENT -- THOUGH
CONDITIONAL UPON THE PRESENCE OF CONVECTION WITHIN THE OTHERWISE
WEAKLY FORCED/WEAKLY RIDGING ENVIRONMENT ACROSS THIS PORTION OF THE
AREA DURING THE AFTERNOON.
...NRN PLAINS AND UPPER MS VALLEY...
EARLY STORMS ARE EXPECTED TO BE ONGOING ACROSS NRN MN NEAR A SFC LOW
WHICH WILL MOVE N OF THE CANADIAN BORDER BY AFTERNOON. THIS ACTIVITY
MAY POSE A HAIL OR WIND THREAT. LATER IN THE DAY...A COLD FRONT WILL
PUSH EWD...EXTENDING FROM CNTRL NEB INTO CNTRL MN BY 00Z. STRONG
INSTABILITY IS FORECAST E OF THE FRONT...BUT THE MAIN LIFTING
MECHANISM WILL BE N OF THE AREA. STILL...CONVERGENCE ALONG THE FRONT
SHOULD RESULT IN AT LEAST ISOLATED SEVERE STORMS. STRONG MEAN WIND
FIELDS AND THE LINEAR FORCING MECHANISM SUGGESTS A POSSIBLE LINE OF
CELLS AND/OR A LINEAR MODE WITH WIND AND HAIL POSSIBLE.
– 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.
– 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.
– 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.
– 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.

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.
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 Low: 60F (Record: 39F set in 1876)

THUNDERSTORMS CAPABLE OF PRODUCING VERY LARGE HAIL AND STRONG WIND
GUSTS ARE POSSIBLE LATE SATURDAY AFTERNOON INTO SATURDAY NIGHT FROM
NORTHERN MONTANA ACROSS NORTH DAKOTA...AND ACROSS PARTS OF NORTHERN
MINNESOTA DURING THE DAY. A FEW STRONG STORMS CANNOT BE RULED OUT
OVER LOUISIANA AND SOUTHERN MISSISSIPPI DURING THE DAY.
GRADUAL DEAMPLIFICATION OF THE LARGE-SCALE PATTERN IS PROGGED ACROSS
THE U.S. THIS PERIOD...AS A TROUGH CONTINUES TO EXIT THE E COAST AND
PROGRESS INTO THE WRN ATLANTIC. AS THIS OCCURS...BROAD/FLAT RIDGING
WILL EXPAND TO ENCOMPASS MUCH OF THE COUNTRY...EVEN TO THE EXTENT OF

THE START OF THE PERIOD. BY THE END OF THE PERIOD...THIS LOW IS

AT THE SURFACE...A COLD FRONT IS EXPECTED TO HAVE SAGGED SWD INTO
THE NRN PLAINS VICINITY...BUT SHOULD BEGIN RETREATING NWD AS A
DEVELOPING SURFACE CYCLONE SHIFTS EWD ACROSS MT DURING THE DAY IN
RESPONSE TO THE AFOREMENTIONED PAC NW UPPER SYSTEM. AS THIS LOW
ADVANCES ENEWD THROUGH THE SECOND HALF OF THE PERIOD...A TRAILING
COLD FRONT WILL ADVANCE SEWD ACROSS THE INTERMOUNTAIN W...WITH THE
LOW AND NRN PORTION OF THE FRONT REACHING THE NRN PLAINS HIGH PLAINS
BY THE END OF THE PERIOD.
SCATTERED SEVERE STORMS ARE POSSIBLE SUNDAY FROM THE EASTERN DAKOTAS
ACROSS MUCH OF MINNESOTA AND INTO NORTHWEST WISCONSIN WITH HAIL AND
A STRONG BUT LOW-AMPLITUDE SHORTWAVE TROUGH WILL SKIRT THE NRN
PLAINS ON SUNDAY WITH SURFACE LOW MOVING FROM ND INTO ONTARIO AND A
COLD FRONT EXTENDING SWWD INTO THE NRN PLAINS AND UPPER MS VALLEY.
THIS FRONT WILL PROVIDE A FOCUS FOR A FEW SEVERE STORMS...SUPPORTED

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.
