Fairly Quiet & Partly Sunny Thursday
A mostly quiet Thursday is expected in the Twin Cities, with partly sunny skies and a slight chance of seeing a shower or storm move on through at times. Morning lows only drop into the low 70s with afternoon highs in the mid-80s.
Looking statewide for your July 7th, we will watch the chance of some showers (and maybe a rumble or two of thunder) across portions of northern and southern Minnesota. Rainfall coverage is expected to be only scattered. Highs will climb into the 70s and 80s across the state.

80s This Weekend With Strong Storms Possible Sunday
If you're looking to get out this upcoming weekend, parts of it won't be too shabby for the first half of July! Friday and Saturday will feature mainly sunny skies with highs in the low to mid-80s. Dew points will also only be in the 50s those two days, so it won't feel as sticky out. On Sunday we will see the stickiness factor start to creep upward again as dew points reach the mid-60s during the day. We will also watch the threat of some thunderstorms across the state.
A few of those storms on Sunday could be severe, with the equivalent of a Slight Risk of severe weather (threat level 2 of 5) already in place for the potential of at least one round of storms during the day into the overnight hours along and ahead of a cold front. We will keep an eye on this severe threat over the next several days.

11th 90F Of 2022 Tuesday
We hit 90F for the eleventh time this year on Tuesday at MSP Airport. We are almost at the average for the entire year now, as the 1991-2020 average is 13. Using the same 30-year average, the most 90F degree days typically occur in July (on average 5 of the 13 days). The eleven days through July 5th is the 13th most to date on record. Last year we had 14 90F degree days through July 5th.

Derecho Occurred Across The Northern Plains Tuesday
A linear complex of storms moved across South Dakota into northern Nebraska, southern Minnesota, and parts of Iowa on Tuesday, bringing destructive wind gusts and some large hail. This complex has been declared a "derecho". What is a derecho? Here's what the Storm Prediction Center says: "By definition, if the swath of wind damage extends at least 400 miles (about 650 kilometers), is at least 60 miles (about 100 km) wide, includes wind gusts of at least 58 mph (93 km/h) along most of its length, and also includes several, well-separated 75 mph (121 km/h) or greater gusts, the event may be classified as a derecho."

It Gets Cold Here But At Least We Have Water
By Paul Douglas
Minnesota's biggest asset? Something you can't go without for about 3 days: H2O. Water is Minnesota's biggest advantage, now and going forward. In a warming atmosphere droughts are becoming super-sized, lasting longer, impacting more people.
The World Wildlife Fund estimates 1.1 billion people worldwide lack access to water. 2.7 billion people experience water scarcity at least one month a year. God knows we have issues, but we have an abundance of water in aquifers and 14,380 lakes. They're fun to swim in too.
My lawn is looking crunchy, so remind me not to whine about a few showers later today. Not the soaking we need, but bring on the puddles. A faint puff of drier, Canadian air treats us to 80s, sunshine, and slightly lower dew points Friday and Saturday; probably the nicer day of the weekend (if you like applying sunscreen). Weather models hint at Sunday T-storms, followed by slightly cooler weather next week.
NOAA's GFS model shows a string of 90s the third week of July. Circle your calendars.

This Day in Weather History
July 7th
2000: Torrential rains douse the southern Twin Cities metro area with 8 inches in a three to five hour span in northern Dakota county. Eagan receives the most damage; many homes were flooded.
1955: A tornado hits Marshall, leaving one dead and 13 injured. Hail causes one million dollars in damage.

National Weather Forecast
We will continue to watch shower and storm potential across a good portion of the lower 48 on Thursday, particularly from the Northern Rockies down into the Plains, Ohio Valley, and Mid-Atlantic with a frontal boundary in place. A few record highs could be possible in the Southern Plains.
As we watch more rounds of showers and thunderstorms across portions of the Plains to the Ohio Valley around the bubble of heat that has formed in the central and southern Plains, rainfall tallies through Friday evening could top 3" in some locations.

Australia flood, boosted by climate change, making history in Sydney
More from the Washington Post: "A potent weather system near Australia's east coast has unloaded tremendous rainfall in the state of New South Wales for days, putting Sydney on track for its wettest year on record. The torrents have spurred widespread flooding in eastern parts of New South Wales, for the fourth time in less than 18 months. The flooding has triggered more than 100 evacuation orders. Since Friday, Sydney has observed 8.6 inches (220 mm) of rain, while surrounding areas have seen far more — some approaching 28 inches (700 mm) — which is around the amount London sees in an entire year."
Great Salt Lake is 'in trouble' as level falls to lowest on record for second year in a row
More from CNN: "The Great Salt Lake in Utah has dropped to its lowest level on record for the second time in less than a year as a climate change-fueled megadrought tightens its grip in the West. The lake's surface water elevation fell to 4,190 feet on Sunday, according to data from the US Geological Survey — below the previous record set in July 2021 and the lowest it has ever been since it was first measured in the mid-1800s. Before last year, the lake's low record was 4,191.4 feet in October 1963. Utah officials are now calling for "urgent action" to preserve the Great Salt Lake amid its third straight year of decline."
Large Hadron Collider Physicists Discover Three New Exotic Particles
More from Gizmodo: "Physicists at CERN's Large Hadron Collider announced today the discovery of three exotic particles that may help reveal how quarks bind together. One particle is a pentaquark (a hadron made up of five quarks) and the other two are tetraquarks. They were found by the LHCb Collaboration at CERN, which uses a 5,600-ton detector on a portion of the Large Hadron Collider to investigate differences between matter and antimatter. Last year, the collaboration found the first double-charm tetraquark, the longest-lived exotic matter particle yet found. The newly discovered particles add to the collaboration's running list of exotic particles."
