Windy Day Ahead...
A large are of low pressure centered over Ontario will allow strong winds to blow across the region today and tomororw. Some of the wind gusts could approach 40mph across parts of Southwestern Minnesota, including the Twin Cities later today. Here is the wind gust loop from 7am to 7pm Monday.
Cool and Windy Monday
Here's the latest information from the National Weather Service about today's cool and windy weather:
"It will feel more like fall today as a brisk west-northwest wind continues, and temperatures only manage to rise into the upper 50s to mid 60s. Tuesday will see a few more showers in east central Minnesota and west central Wisconsin. The remainder of the week will be dry and more seasonable with highs generally in the 60s, with overnight lows in the 40s and 50s."
Colder Temps in the Northeast
Take a look at the tweet that the NWS out of Washington DC/Baltimore sent out on Sunday morning. Due to colder temperatures moving into the region, the tempeature dipped below 60F for the first time in 107 days. That makes it the 2nd longest stretch with temperatures at 60F or warmer in recorded history.
Scattered showers popped up in the wake of our cold front on Sunday. Note the speckled nature of the clouds, which shows the instability present in Sunday's atmosphere. Temperatures aloft were quite chilly, so any amount of sunshine and daytime heating helped to produce the random showers.
Signs of Fall Closer to Home
Slowly, but surely signs of fall are beginning to pop up. A few more trees and bushes are beginning to turn color and over the few weeks, we will be inundated with brilliant colors everywhere!
The latest update from the MN DNR shows that we are well on our way in the fall color department with some 50% to 75% color being reported across parts of Central and Northwestern Minnesota. Note that only 10% to 25% color can be found across the Twin Cities; the average peak there is generally late September to mid October.
More on the Record Setting September Rain
September continues the very wet trend we've been seeing across the Upper Midwest over the last several months. Much of the significant tallies were aided by pockets of extreme rainfall earlier this week. Mark Seeley from MN State Climate Office recently wrote about the recent rains in Friday's WeatherTalk, his work can be found below:
"Thunderstorms, some severe, brought heavy rainfall again to portions of central and southern Minnesota over September 21-22 (Wed-Thu) this week. Many observers reported from 1 to 2 inches, and several places reported new record daily amounts up to 5 to 8 inches. Dew points spiked in the low 70s F at a number of locations just ahead of the storm indicating that there was a very high water vapor content. Preliminary data suggest that a new statewide record daily rainfall occurred on September 22nd (old record 4.84 inches at Cambridge in 1968), but the final say on the new record will come from the Minnesota State Climatology Office. Many communities reported flash flooding, including washed out roads and culverts, and some flooded basements."
Some of the new record daily amounts of rainfall included:
7.64" at Waseca
5.15" at Wells
4.11" at Rochester
4.06" at Bricelyn
3.81" at Preston
3.74" at Spring Grove
3.70" at Zumbrota, Grand Meadow, and Spring Valley
3.09" at Winnebago
3.08" at Theilman
2.75" at La Crescent
2.15" at Stillwater
2.10" at Winona Dam
2.06" at Kimball
Many other communities with shorter climate records reported even greater amounts of rainfall, including 5.34" at Lanesboro, 5.11" at Eau Claire, WI; 4.65" at Champlin; 4.15" at Owatonna; 8.11" at Maple Grove; and 5.12" at Byron.
The added rainfall this week pushed the total for the month of September to near record or new record values for a number of climate stations in southern Minnesota, including:
13.69" at Mabel (Fillmore County)
13.89" at Spring Grove (Houston County)
10.37" at Spring Valley (Fillmore County) 10.56” at Rushford (Fillmore County)
11.40" at Hokah (Houston County)
13.03" at Caledonia (Houston County)
14.56" at Waseca (Waseca County)
"This wet September continues a trend toward above normal precipitation. Some climate stations in Minnesota have already received over 40 inches of precipitation for the year. Further at least ten climate stations are on a pace to set a new record wet year, including St James with 40.59 inches (2nd wettest year in history), and Waseca with 48.68 inches (2nd wettest year in history), and over three months to go in 2016! It is also likely that the all-time state record wettest single year, 53.52 inches at St Francis (Anoka County) in 1991 will be broken before the end of this year."

River Flooding Continues
Keep in mind that not all the rivers that are experiencing flooding are shown below, but those with river gauges that are currently registering flood stage are. Note that quite a few are in Major Flood stage across parts of northeast Iowa and across western Wisconsin.
Soggy Baseball Weather This Year
It was another soggy day at Target Field on Friday, September 23rd. Interestingly, there have been nearly a dozen rain delays/postponements this season, which speaks to the number of soggy days we've had this summer. Al Kuehner, the official Target Field co-op weather observer, has measured a staggering 29.62" of rain so far at Target Field since the Twins' season started back in April! Here's how the months tallied up:
September (So far): 5.38"
Chilly winds today. Dry and warm for Ryder Cup
Break out the long sleeves and slow cook something in the Crock-Pot. I always hate to see summer go, but I am reminded how much I like Fall once the temperatures dip and trees start turning color. We're also getting closer to the end of road construction season and that's a major plus!
The mercury struggles to get to 60 degrees across much of northern Minnesota today as low, gray clouds and scattered light showers rotate around a slow moving storm system. The storm loiters in the Great Lakes region through the early week time frame, which means we'll have to deal with a nagging, Octoberish breeze; one that will have you reaching for an extra layer before leaving the house in the morning.
As the stubborn storm drifts east, a ridge of high pressure builds in allowing sunshine and dry weather to persist for several days. Golfers and golf fans will be appreciative of the downpour free forecast as the Ryder Cup comes to town this week.
At this point, the weekend looks dry with temperatures hovering around 70 degrees. FORE!

Weather Outlook Monday
Monday looks like a chilly day across the region with highs struggling to get to 60 degrees across parts of the state. Dewpoints will be quite low, so it'll feel like a fall day!
Weather Outlook Monday
Winds on Monday will begin picking up out of a westerly direction, which will help to keep the colder temperatures in place. Note that winds will be fairly stout across western Minnesota and across the Dakotas.
Weather Outlook Monday
The cold front that brought steadier rain showers PM Saturday/AM Sunday will be found across the Great Lakes Region and Middle-Mississippi Valley on Monday. In the wake of the front, wrap around could and a few spotty showers will still be possible.
Wrap around showers on the western and southwestern flank of an area of low pressure centered over Ontraio will continue to wrap through northeastern Minnesota and northern Wisconsin. This steady light rainfall could add up to 0.50" or more through the early week time frame. Additional light rain showers may be possible in the Twin Cities region on Tuesday, but should amount to much.
Extended Weather Outlook
The extended temperature outlook over the next 10 days suggests temperatures dropping back down to below average levels through the middle part of next week in the wake of the cold front that moved through PM Saturday/AM Sunday. Slowly, temperatures climb to near average levels by the end of the week and into the first part of October!
6 to 10 Day Temp Outlook
According to NOAA's Climate Prediction Center, warmer than average temperatures look to sneak back into the Upper Midwest as we get into early October. However, temperatures over the next couple of days look a littler cooler and could require some longer sleeves.
6 to 10 Day Temp Outlook
Here's the national temperature outlook from October 1st - 5th, which shows warmer than average conditions across the eastern two-thirds of the nation with cooler than average temperatures returning to places along the West Coast.
National Weather Outlook
After a notably wet week across the Central U.S. and especially across the Upper Midwest. The last round of steadier showers and storms will move to the East Coast early this week. This will allow for several days of drier weather to settle in across the Upper Midwest, which is much needed after some locations saw nearly 2 to 3 months worth of rain last week. Scattered showers and storms will continue across the Deep South; Texas could continue to see heavy rainfall and flood concerns.
According to NOAA's WPC, the 5 day precipitation forecast shows heavy rainfall tapering across the Upper Midwest with heavier rain taking over in the Northeast and across the southern half of Texa. Some areas could see 2" to 3"+, which cloud lead to flooding.
This was the view of the remnants of Karl from PM Sunday as it was quickly tracking northeast through the north-central Altantic. Karl regained tropical storm status after being downgraded to a depression earlier this week. The good news is that after making a close encounter with Bermuda PM Friday/AM Saturday, Karl will no longer be an issue.
Atlantic 5 Day Outlook
"WMO rules on longest distance and longest duration lightning flashes"
"Experts have established two new world records for the longest reported distance and the longest reported duration for a single lightning flash in, respectively, Oklahoma (United States of America) and southern France. The lightning flash over Oklahoma in 2007 covered a horizontal distance of 321 kilometers (199.5 miles). The lightning event over southern France in 2012 lasted continuously for 7.74 seconds."
