Warm, Sunny Start To September - Rain Possible Friday - Fantastic Labor Day Weekend

While the calendar turns to September (and meteorological fall, which runs September 1 - November 30) on Thursday, it's going to feel more like summer across the region. Morning temperatures start off in the low 60s before climbing to the upper 80s under lots of blue skies and sunshine.

A mainly sunny and quite warm first day of September is expected statewide with highs from the upper 70s to low 90s - 5-15F degrees above average to begin meteorological fall.

Forecast loop from 7 AM Friday to 7 PM Friday.

A cold front will move across the state on Friday, bringing the potential of a few showers and maybe an isolated storm with it as we head throughout the day.

Ahead of that front, temperatures on Friday will climb once again into the 80s across the southern two-thirds of the state - but you can start to see more comfortable weather starting to move into northwestern Minnesota behind it.

A more detailed look at Labor Day shows sunny skies throughout the day with morning temperatures in the 60s and temperatures climbing through the 70s to low 80s as we head through the afternoon.

When we shake out the month of August (numbers do not include the last day of the month on Wednesday), it has ended up being fairly average in the Twin Cities. Through the 30th, it was the 41st warmest August-to-date on record for the Twin Cities and the 48th wettest.

As we look at precipitation statewide, rain fell heavily in parts of the state. Most of the eastern and northern parts were around to above average, with below-average pockets in western Minnesota. In Rochester, it is the 8th wettest August to date (through the 30th).

September Magic Spills Into Next Week
By Paul Douglas

Happily we bask in this warm September sun, which illuminates all creatures " wrote Henry David Thoreau. We will all be basking away into next week with some of the finest weather of the year at our beck and call. I know we still need rain, but it's hard to get too indignant about a postcard-perfect sky.

While California bakes under 100-115F heat, Minnesota will enjoy 80s, even a few 70s this weekend with a fresh breeze. A thunderstorm may bubble up south/east of MSP Friday night, but the pattern isn't ripe for significant rain anytime soon.

Summer is tired, the heat is fading. But before the inevitable flakes of October we get to enjoy one long meteorological encore. Thank you September.

This Day in Weather History
September 1st

1926: Perhaps the most intense rainfall rate ever in downtown Minneapolis falls on this date. 1.02 inches of rain is recorded in six minutes, starting at 2:59pm in the afternoon according to the Minneapolis Weather Bureau. The deluge, accompanied with winds of 42 mph, causes visibility to be reduced to a few feet at times and stops all streetcar and automobile traffic. At the intersection of Second and Sixth Streets in downtown Minneapolis, rushing water tears a manhole cover off, and a geyser of water shoots 20 feet in the air. Hundreds of wooden paving blocks are uprooted and float onto neighboring lawns, much to the delight of barefooted children seen scampering among the blocks after the rain ends.

1807: The earliest known comprehensive Minnesota weather record begins near Pembina. The temperature at midday is 86 degrees, with a 'strong wind until sunset.'

High pressure dominates across a good portion of the lower 48 as we head through Thursday. The best rain chances will be in the South Central and Southeastern regions, where a frontal boundary and a couple of areas of low pressure will be located.

That frontal boundary in the southern United States will be the focus for the heaviest rain through Friday, with the potential of over 3" in some locations. In parts of Texas, this could lead to flooding. Most of the rest of the nation will be dry from late Wednesday into Friday due to that area of high pressure.

More from Scientific American: "For all the images of ski resorts and snow-capped peaks, Colorado is experiencing shorter winters and hotter summers that are increasingly putting people at risk for heat-related illnesses. Yet until this year, the National Weather Service hadn't issued a heat advisory for the Denver metropolitan area in 13 years. That's because the heat index commonly used by the weather service to gauge the health risks of hot weather relies on temperature and humidity. Colorado's climate is so dry that reaching the thresholds for that kind of heat advisory is nearly impossible. But this year, the National Weather Service in Colorado adopted a prototype heat warning index, known as HeatRisk, that is used in California and other parts of the Western U.S. and relies on local climate data to determine how much hotter than normal the temperature will be and what the hazards could be to people."

A New Mexico Town Is About to Run Out of Drinking Water

More from Gizmodo: "A town in New Mexico is facing a triple punch of climate impacts from wildfire, drought, and intense rainfall. The city of Las Vegas, New Mexico is set to run out of drinking water in September, thanks to pollution and debris from the largest wildfire in state history. Some residents at the fringes of Las Vegas, a city some 65 miles (105 kilometers) to the west of Santa Fe, were forced to evacuate in May as the Calf Canyon/Hermits Peak fire raged close by. The city gets its water primarily from a reservoir that feeds off the nearby Gallinas River. The river has now been contaminated by runoff from flooding on the burn scar of the fire, after intense rains in late July fell on the same region burned by the fire just a few months before."

First Solar announces new U.S. panel factory following the Inflation Reduction Act

More from CNBC: "First Solar announced Tuesday that it will build a new solar panel manufacturing facility in the U.S. on the heels of the Inflation Reduction Act, which incentivizes domestic manufacturing. The company will invest up to $1 billion in the new factory, which it plans to build in the Southeast of the U.S. The newly announced plant will be the panel maker's fourth fully integrated U.S. factory. First Solar also said Tuesday that it will spend $185 million upgrading and expanding its existing facilities in Ohio."
