Aiming For Hurricane-Resilience in SW Florida
A stalled warm frontal boundary will fire off more clouds and a spattering of light showers and sprinkles this weekend. We'll take any rain, after the driest September on record. If the sun stays out for a few hours we may hit 70F. Not a bad way to kick off October. Check the blog for more details. -Todd Nelson

Driest September on Record at MSP
Well this kind of snuck up on us, but did you realize that MSP only had a 0.25" of rain for the entire month of September? This will rank as the driest September in recorded history!
Dry September Around the Region
Despite a few pockets of heavy rain here and there, September really was a dry month for many across the Midwest. All of the climate sites in Minnesota were below average with the biggest deficit in the Twin Cities, which ranked as the driest September on record.
Precipitation Departure From Average Since Jan. 1st
Here's the precipitation departure from average across the Midwest since January 1st. Note that there are a few communities that are dealing with surpluses, but for the most part, folks from the Twin Cities to Sioux Falls, SD are running below average. Minneapolis is nearly -7.70" below average, which is good enough for the 23rd driest start to any year in recorded history.
Severe Drought Continues in the Metro
According to the US Drought Monitor (updated September 27th), severe drought continues in the Twin Cities. Areas of moderate to severe drought stretch from the Twin Cities to the MN River Valley, where precipitation amounts are running several inches below average since January 1st.
Mostly Dry Extended Forecast
Here's the precipitation outlook through over the next several days, which shows very little rainfall across the region.
Little Rain Chance Into Early October
Here's the weather outlook through the middle part of next week, which shows isolated rain chances possible, but it doesn't appear that any appreciative amounts will be possible. There is more substantial cooldown that will move through midweek with much cooler air in place during the 2nd half of the week.
"41 Surreal Pictures And Videos Showing The Unreal Devastation Left Behind By Hurricane Ian"
Hurricane Ian was one of the strongest hurricanes to ever hit the Florida coast. In terms of max winds, this will tie with Charlie, but Matthew, Andrew and the Labor Day Hurricane were stronger. Many communities on the west coast of Florida and especially around Fort Myers saw catastrophic damage. The images coming out of Florida are astonishing and heart-breaking. Buzzfeed compiled some unreal images HERE:
Ian Makes Another Landfall on Friday
Here's a look at Hurricane Ian from PM Friday as it made a 2nd U.S. landfall near Georgetown, SC as a category 1 storm with 85mph winds. This was the first South Carolina landfalling hurricane since Matthew in 2016. Gusty winds and heavy rainfall will be possible over the weekend through the Mid-Atlantic States, where some 2" to 5" rainfall tallies can't be ruled out.
Fall Color Update
Thanks to dwindling daylight and chilly overnight lows, the fall color progress is really starting to come around. It won't be long now and those fall colors will be quite prevalent across the state. Enjoy!
Average Fall Color
The MN DNR has put together a nice graphic that shows typical dates for peak fall color. The northern par of the state starts to peak during the 2nd half of September into early October. Meanwhile, folks in the central part of the state and into the metro typically don't see peak color until the end of September into the middle part of October. It won't be long now - enjoy!

Aiming For Hurricane-Resilience in SW Florida
By Paul Douglas
The area so many Minnesotans favor for sunny, sandy getaways looks like a war zone. Residents have been through a trauma. Here is a prediction I'll get right: Southwest Florida will be back.
I hope the area builds back stronger, in every sense of the word. In a time of rising seas and increasingly super-sized hurricanes, there's an opportunity to create hurricane-resilience: stronger building codes, elevated structures and more natural green-spaces to buffer future storm surges. Even retreating from the water where it makes sense. That won't be easy, but it may become necessary.
A stalled warm frontal boundary will fire off more clouds and a spattering of light showers and sprinkles this weekend. We'll take any rain, after the driest September on record. If the sun stays out for a few hours we may hit 70F. Not a bad way to kick off October.
A brief slap of cooler air arrives late next week, but models show a milder than average trend into much of autumn. Peak fall color has been delayed by 1-2 weeks.

Climate Stories
"Shifting ocean currents are pushing more and more heat into the Southern Hemisphere's cooler waters"
"The oceans absorb more than 90% of all extra heat trapped by the emissions we've produced by burning fossil fuels. This heat is enormous. It's as if we exploded an atom bomb underwater, every second of every day. The ocean isn't warming at the same rate everywhere. We know the heat is concentrated in the fast, narrow currents that flow along the east coasts of the world's continents and funnel warm water from the tropics down towards the poles. In the Southern Hemisphere, these currents – known as the western boundary currents – are warming faster than the global average at their southern limits, creating ocean warming hotspots."
"Study identifies hundreds of hospitals on Atlantic and Gulf Coasts at risk of flooding from hurricanes"
"The first study to systematically investigate flooding risk to hospitals on the Atlantic and Gulf Coasts from Category 1-4 storms finds that even relatively weak storms pose a serious flood risk to hospitals along the coast. Sea level rise expected in this century due to the effects of climate change increases the odds of hospital flooding by 22% according to a study, which was published today in GeoHealth by the Center for Climate, Health, and the Global Environment at Harvard T.H. Chan School of Public Health, Boston University School of Medicine Department of Family Medicine, and PSE Healthy Energy."
"Discovery of 'fingerprint' confirms alarming predictions of Greenland ice sheet melt"
"Scientists now have unambiguous proof that a phenomenon critical to predicting the impact of climate change exists. Researchers announced Thursday that they had detected the sea level "fingerprint" of the Greenland ice sheet melt, pinpointing the unique pattern of sea level change linked to the melting ice. It's the first time such a fingerprint has been definitively measured. While scientists agreed such fingerprints theoretically exist, the dynamic nature of the ocean had made it difficult to identify them confidently — until now."
