That's a freeze times two! Maple got down to 32 today and Knight hit 29! The autumnal equinox hits at 7:05 pm tonight, and the weather is certainly reflecting it!

Fall arrives today at 8:05 pm ET! 🍂 Today’s Fall Equinox marks the start of astronomical fall in the Northern Hemisphere and is the moment when the Sun is directly over Earth’s equator. From now through the Winter Solstice on December 21, the Northern Hemisphere will receive increasingly less direct sunlight as Earth continues along its tilted orbit around the Sun.

El Niño is strengthening, with a greater than 90% chance of a very strong event during the Northern Hemisphere fall and winter 2026-27. An #ElNino Advisory remains in effect. #ENSO cpc.ncep.noaa.gov/products/a…
A bar chart showing the chance of El Niño (red bars), ENSO-Neutral (grey bars), and La Niña (blue bars) provided for 9 upcoming, overlapping 3-month seasons (each letter represents a month, for example, F = February). The color shading within the bars indicates the chances of different categories of El Niño or La Niña strength (weak, moderate, strong, and very strong). Alternatively, the table at the internet address below presents the percent chances of each strength category in numerical form. https://cpc.ncep.noaa.gov/products/analysis_monitoring/enso/roni/strengths/

The new Drought Monitor is out. There isn't a significant change from last week, but a little bit more of southern Wisconsin has been added to the Abnormally Dry category. Most of the state received less than an inch of rain in the past week and soils continue to dry out.

According to @NOAANCEI, last month beat out July 1936 to become the warmest month on record for the contiguous United States. July 1936 was peak Dust Bowl heat for us, with the Dells hitting 114°F on July 13 - the state's record highest temperature.

A heat dome over the U.S. causes temperatures to soar across the country, while monsoon season is kicking off in the Southwest U.S. The outline of the heat dome and monsoon moisture can be seen from clouds and water vapor arching from the Pacific Ocean and across the continent.

Heat waves have the potential to cover a large area, exposing a high number of people to a hazardous combination of heat and humidity, which can be very taxing on the body. Learn how to stay safe during a heat wave at weather.gov/heat #wiwx

Starting this weekend, Major to Extreme HeatRisk will begin spreading into the Midwest, Deep South, and southwestern U.S. As blistering as the daytime highs will be in many areas, record-warm morning lows will heighten the danger for those unable to seek cool shelter. Ensure your loved ones and neighbors stay safe from the heat, and remain #WeatherReady.
