This is summer? Epic Minot flood; EF-0 Tornado confirmed

Summer arrived Tuesday with tornado warnings heavy rain. Wednesday features April-like temperatures in the 50s & 60s and a raw northwest wind.

The unseasonably cool weather pattern may have Minnesotans saying, “If this is summer, give me back spring!”

81 degrees-average high temperatures for June 22nd

64 Twin Cities temp at 4pm today

17 degrees below average!

Wind chill? in June??

It’s hard to fathom, but our unseasonably strong and chilly spring like storm system in June will leave us feeling the chill through Thursday.

The incredibly potent out of season mid-latitude cyclone streteches for Canada to the Gulf of Mexico. Take a look at the massive system on Wednesday’s MODIS Terra visible satellite image.

Temperatures under the comma shaped head of the storm over Minnesota are running a full 20 degrees cooler than average for June 22nd. It’s in the 50s in much of northern and central Minnesota!

Factor in the wind and it actually feels like upper 40s in some areas…and this is June!

Forecast improves Friday:

The slow moving system should finally begin to pull out of Minnesota Friday. Look for a return to sunshine from west to east…and temperatures will recover into the 70s in most areas.

Iffy Weekend?

The weather maps look like somebody put a target right over Minnesota. The jet stream has been close to or directly overhead for months now, and the next weather wave may race in Saturday with another chance of spotty showers.

The wave should clear Minnesota by Sunday. If everything works out right, Sunday could be the sunnier, warmer more summer like day this weekend with highs near 80 in the south.

Epic flooding in Minot, ND:

Combine high runoff from heavy winter snows and the wettest May & June on record since 1945 in North Dakota and what do you get?

An epic flood with tragic consequences unfolding this week in Minot, North Dakota.

The Souris River is reaching record flood levels this week, and is expected to breach Minot’s flood protection by Thursday. As many as 12,000 of Minot’s 40,000 residents are evacuating, as sirens wail to sound the warning.

The Souris begins in Saskatchewan and flows southeast into Minot before turning back northeast into Manitoba. It is part of the Red River drainage system.

The river is already 7+ feet above flood stage in Minot, and is expected to rise another 3-5 feet this week.

.A SHARP RISE ON THE SOURIS RIVER NEAR SHERWOOD WAS OBSERVED

LATE TUESDAY NIGHT INTO WEDNESDAY MORNING. THE USGS MEASURED

A FLOW OF 21900 CFS ON THE SOURIS RIVER NEAR SHERWOOD WEDNESDAY

AFTERNOON. THE RISE PAST SHERWOOD OCCURRED FASTER THAN PREVIOUSLY

ANTICIPATED DUE TO THE UNCERTAINTY OF ROUTING WATER FROM ESTEVAN

TO SHERWOOD AT THESE HIGH LEVELS. THE FASTER ARRIVAL OF HIGHER

FLOWS INTO LAKE DARLING HAS PREVENTED THE POOL ELEVATION FROM

DROPPING AS LOW AS PREVIOUSLY EXPECTED…AND WILL NECESSITATE THE

RELEASES TO BE INCREASED TO 18 THOUSAND CFS ON JUNE 18TH AND 22

THOUSAND CFS ON JUNE 22ND. THE CURRENT RELEASE SCHEDULE IS TO

HOLD AT 22 THOUSAND CFS THROUGH JUNE 29TH.

WITHIN THE CITY OF MINOT…LEVEES WILL CONTINUE TO BE OVER TOPPED

AS RIVER LEVELS CONTINUE TO RISE. THE SOURIS RIVER LEVEL THROUGH

MINOT IS LIKELY TO FLUCTUATE UNTIL WATER HAS FILLED THE STORAGE BEHIND

THE LEVEES.

DUE TO UNCERTAINTY IN THE STAGE-RATING CURVE AT RECORD LEVELS…

ONE SHOULD ADD OR SUBTRACT ABOUT A HALF A FOOT FROM THE FORECAST

LEVELS PROVIDED BELOW TO ARRIVE AT A PLAUSIBLE RANGE OF RIVER

LEVELS

Minot is the latest crisis point in what’s really been a year of bad (and record) weather for the Upper Midwest.
