Wet June may end drought in some areas

"It takes a flood to end a drought."

That's one of the many weather related quotes attributed to Mark Twain.

We may not get a flood, but the end of the drought may be in sight for parts of the Upper Midwest.

An active jet stream overhead is dealing frequent low pressure systems to Minnesota this month. After a mostly dry but windy Wednesday, the next system is already taking aim.

This one could be the wettest of the bunch.

Take a look at some of the various rainfall projections for the next few days.

The forecast models we use are notoriously aggressive with summertime, convective rainfall forecasts, but the set up the next few days may lead to some impressive rainfall totals in some areas. Anytime you get dew points surging toward the tropical 70 degree mark, you can get tropical and potentially flooding downpours.

Check out the anticipated surge in dew points in the metro by Friday.

Some forecast models push dew points to the sticky, tropical 70 degree mark Friday.

With that kind of tropical moisture around, the next wave of rain may feature a little more thunder. There's no shortage of moisture for crops this year. SPC keeps the main risk of severe weather just south and west.

Enjoy our windy Wednesday. A pop up shower is not out of the question today, especially in the northern half of Minnesota and Wisconsin. This will be the best day of the week to get the lawn under control before another good soaking rain rolls in.

Seats dictate weather at Target Field

It can be like spring or summer in Target Field at the same moment, depending on where your seats are.

At a recent Twins/Yankees game I took the time to visit several different sections and "take the temperature" of the seats and the fans. What I found are temperatures that vary widely in different sections of Target Field at the same time.

While it is not a surprise to find changing temperatures in Target Field, the magnitude of the difference in the apparent or "feels like" temperature was remarkable. It was like the difference between a cool spring day and a warm summer afternoon depending on the section number on your ticket.

Thursday May 27th
Time: 6:30pm
Location: Left field seats section 313.
-Air temperature: 80 degrees.
-Apparent temperature: Near 90 degrees.

I enter Target Field through Killebrew Gate 3 in center field. Under the crowded but shady concourse with the breeze it feels very close to the ambient air temperature of 80 degrees. But as I emerge into the direct sunshine in the left and center field bleachers, it's instant July.

The seats are very warm to the touch. The fans are dressed for summer. My low tech thermometer and weather spidey senses tell me the apparent or "feels like" temperature in the sun soaked center field seats is close to 90 degrees. Center field faces directly west into the now sinking but still potent evening sun, and you can feel every degree.

Time: 7:10pm
Location: 3rd base line near section 11, row 1 .
-Air temperature: 77 degrees.
-Apparent temperature: 74 degrees.

As Nick Blackburn throws the game's first pich to Derek Jeter, I am in the press pit next to the Yankee dugout at field level just below the first row of section 11.

The shade of the stadium's high canopy has covered the area along the 3rd base line now for some time, and the temperature is noticeably more comfortable than it was in the outfield just minutes earlier.

There is now a slight breeze to subtract just a few more degrees from the apparent temperature. I would estimate the feels like temp here is a cozy 74 degrees as the game starts.

Time: 7:30pm
Location: 1st base side concourse at the top of section 109 .
-Air temperature: 74 degrees.
-Apparent temperature: 68 degrees.


I make my way to the concourse along the first base line behind section 109. This area has been in shade pretty much all day. It now feels considerably cooler here. The breeze blowing through the openings in the concourse is cool to the senses. I notice many fans here wearing sweatshirts, even as T-shirt clad fans in center field soak up the last rays of evening sun across the stadium.

Conclusion:

On this relatively warm summer like evening at Target Field, I observed differences in apparent temperature in different sections of the ball park of as much as 22 degrees over a period of about an hour. On this day it was relatively warm, but it would be good to know where you're sitting on a sunny day as you decide how to dress for the game.

I talked with Kevin Smith, Twins media guru about the stark contrast in temperatures around Target Field. His observations seem to indicate that the biggest differences occur on sunny, relatively cool and breezy spring days with temperatures in the 60s. He has seen fleece in the upper deck sections along the 1st base line and shorts and T-Shirts in the sun down the 3rd base line during cool sunny day games.

Bottom line: Know your seat, sun angles and the expected weather before you head out to Target Field this summer.
