Very Pleasant Sunday Expected With Highs In The Mid 80s

Saturday Late Morning/Early Afternoon Severe Storms

Yellow dot = wind damage/gust.
Storms rolled through the metro area during the late morning/early afternoon hours with strong wind gusts, knocking down some trees and power lines. There was a 52 mph wind gust reported 8 miles SSE of Cannon Falls, and a 48 mph wind gust 2 miles west of Bay City, WI.
Very heavy rain also fell just north of the metro with storms, including 5″ reported in the Howard Lake area, 4.50″ in Ramsey, and 3.75″ in Monticello.

Guiding A Ship Through 80-100+ mph Winds
As the severe storms blew through Duluth early Thursday morning, the Algoma Guardian was just entering the Duluth ship canal. The Duluth News Tribune has the story of how the captain of the ship prevented it from going into the side of the canal, and of the bridge operator who had to ride out the wind at the top of the structure. Of note, the bridge’s wind gauge saw a peak gust of 80 mph, but the Algoma Guardian saw a peak gust of 103 mph. Here a clip from the beginning of the story: “A 729-foot freighter was making its way through the Duluth ship canal when the winds began to howl early Thursday. As the strong straight-line winds from severe storms began to quickly turn the Algoma Guardian sideways in the canal, Capt. Monford Organ’s main concern was getting the freighter into the Duluth Harbor Basin without any damage.
Dennis O’Hara posted on YouTube the webcam footage of the Algoma Guardian going through the Duluth canal and under the bridge early Thursday morning, which is where the above image comes from.

July 23-24, 1987 Flooding
This year marks the 29th anniversary of the 1987 flooding across the Twin Cities, which brought much of the metro very heavy rain. The Twin Cities airport picked up 10″ of rain over the two days, 9.15″ of that falling on the 23rd. That day goes down in history as the wettest day in Twin Cities history. Here’s some more information on the heavy rain from climate historian Tom St. Martin that the Minnesota Climatology Working Group posted a few years ago on the 25th anniversary:

The heaviest rainfall ever officially recorded at a Twin Cities weather station fell between about 1800 hours CDT on 23 July and about 0200 hours CDT on 24 July 1987. During this eight hour interval, observers at the Twin Cities International airport station measured an even ten inches of rain (9.15 inches of which fell in a five hour period). And, although it escaped the worst of the storm, most parts of St. Paul received totals in the five to seven inch range, including 5.47 inches at the St. Paul NWS cooperative station; 5.30 inches at the North St. Paul NWS cooperative station; and 6.03 inches at the compiler’s St. Paul Battle Creek area station. In addition to the heavy rainfall, the 23-24 July storm spawned a tornado which first touched down at about 1900 hours CDT near Goose Lake in the northwestern corner of the Twin Cities area. The funnel then moved in a southeasterly direction, causing extensive damage in the Twin Cities suburbs of Maple Grove and Brooklyn Park. Damage in other areas (including St. Paul) was extensive, largely the result of flooded homes and businesses, ruptured storm sewers, and washed out or inundated streets and highways. Two flood related deaths were reported and property damage was estimated to be in excess of $30 million (by any calculation, one of the greatest weather related losses ever to occur in Minnesota).

129° In The Middle East

3 PM (local time) temperatures Friday. Map: Aeris Weather.
Think it has been hot here recently? The thermometer hit 129 in at least two Middle East locations last Thursday and Friday. The Capital Weather Gang has more: “The temperature in Mitribah, Kuwait, surged Thursday to a blistering 129.2 degrees (54 Celsius). And on Friday in Basra, Iraq, the mercury soared to 129.0 degrees (53.9 Celsius). If confirmed, these incredible measurements would represent the two hottest temperatures ever recorded in the Eastern Hemisphere, according to Weather Underground meteorologist Jeff Masters and weather historian Christopher Burt, who broke the news.

Free Solar Energy Returns Today – 80s This Week
By Paul Douglas
Don’t think the atmosphere and oceans are warming? Acknowledge the science – or don’t. We may disagree on the severity of the problem, but I suspect we might agree on a solution.
We need more energy, want to pay less, with fewer unpleasant side effects and dependencies. The cost of solar is dropping faster than the price at the pump.
Citizens League is hosting a clean energy conference in Minneapolis on Monday, focused on conservative, economy-empowering solutions. “The pace of decarbonization is ultimately going to be driven by economics, not politics” said David Strom.
The swarm of severe, flooding thunderstorms, the sprawling “MCS system” that fouled up your Saturday plans, gives way to a drying northwest breeze today. The sun comes out with mid-80s and a dew point in the 60s. A salvageable Sunday!
The good news: the heat wave is history, at least looking out 2-3 weeks. No more sultry 90s, but instability T-showers may sprout each afternoon from Tuesday into next weekend.
With flooded basements and downed trees, many of us could use a break. It arrives today.

This Day in Weather History
July 24th
1987: A historic deluge ends in the Twin Cities. Two-day totals include over a foot of rain at Bloomington. Nearly 10 inches falls in downtown Minneapolis, and near 9 inches is recorded in St. Paul. At one time the water reaches a depth of 13.5 feet on I-494 near East Bush Lake Road. I-494 in Bloomington would be closed for nearly 5 days.
1891: Heavy frost hits Elkton in Mower County in southeast Minnesota. The frost kills all vegetable crops. The low in Elkton is 34, and the Twin Cities have a low of 49.

Sunday And Beyond Minnesota Weather Outlook

We’ll see temperatures a little cooler Sunday behind the cold front, with highs only making it into the mid 80s here across the Twin Cities.

4km NAM forecast clouds and precipitation for 1 PM Sunday. Map: Aeris Weather.

The good news is that Sunday will be much calmer across Minnesota with mainly sunny skies expected across the southern portions of the state. A few more clouds can be expected across northern Minnesota.
Looking into the future, temperaturewise, our weather models are hinting at a little cool down as we head into late this week, with highs nearing 80 by next Friday/Saturday. However, the long term forecast shows the signal of potentially another heat burst as we head into the first week of August. This bears watching over the next week or so to see if it sticks around in the models or fades away.

National Forecast Outlook
Storms will be possible in the central Plains and Ohio Valley along a cold front moving through the region – the same one that brought Minnesota storms Saturday. A weak upper level low will bring the chance of some showers and storms to parts of the Southeast. Some storms will also be possible in parts of the Southwest. Some of the storms over the upper Great Lakes and the central High Plains could be strong to severe, with hail and wind the main threats.
Much of the nation will be warm on Sunday, with highs in the 80s expected in each state across the lower 48. 90s will be possible as far north as parts of Nebraska to the New York City area.
The heaviest rain Sunday will be across central parts of the U.S., where 1″ or more will be possible. More rain is possible across parts of the Gulf Coast, with the potential of at least a half an inch.
