...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.

- 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.
Grandma's Marathon - Hot and Sticky for Dad's Day
By Todd Nelson, filling in for Douglas.
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.
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)
*Daylight gained since Winter Solstice (December 22nd): ~6hours and 51mins
1.2 Days Until Full (Strawberry) Moon
...SUMMARY... 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. ...SYNOPSIS... 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 HINDERING THE INLAND ADVANCE OF AN UPPER LOW OFF THE PAC NW COAST AT THE START OF THE PERIOD. BY THE END OF THE PERIOD...THIS LOW IS PROGGED TO HAVE BEEN SHUNTED NEWD TO THE WA/NRN ID/SRN BRITISH COLUMBIA VICINITY...WHILE A BROAD ZONE OF ENHANCED WSWLY FLOW /ON THE NRN SIDE OF THE FLAT U.S. RIDGE/ EXTENDS FROM THE NWRN U.S. ENEWD ACROSS THE U.S./CANADA BORDER REGION AND INTO QUEBEC/ONTARIO. 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.
...SUMMARY... SCATTERED SEVERE STORMS ARE POSSIBLE SUNDAY FROM THE EASTERN DAKOTAS ACROSS MUCH OF MINNESOTA AND INTO NORTHWEST WISCONSIN WITH HAIL AND WIND EXPECTED. ...SYNOPSIS... 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 BY STRONG WIND FIELDS ALOFT AND AMPLE MOISTURE AND INSTABILITY. MEANWHILE...AN UPPER HIGH WILL REMAIN OVER THE FOUR CORNERS STATES...WITH GENERAL THUNDERSTORMS ALONG THE GULF COAST S OF THE RIDGE.
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.
