MINNEAPOLIS, MINN. — A taste of fall may be on the way for the Midwest, with the National Oceanic and Atmospheric Administration’s latest 8 to 14 Day Temperature Outlook pointing to below-normal temperatures across Minnesota, Wisconsin and the Great Lakes region for the period running September 16 through 22, potentially bringing highs in the 70s and lows in the 50s to parts of the region.
NOAA’s Official Outlook Points to a Cooler Mid-September for the Midwest
The Climate Prediction Center’s outlook, issued September 8 and valid for the September 16 through 22 window, shows a clear below-normal temperature signal stretching across the Upper Midwest and Great Lakes, an area including Minnesota, Wisconsin, Michigan and parts of northern Iowa, Illinois and Indiana. This official government outlook adds additional weight to a cooler pattern that private forecasters have also been flagging in recent long-range outlooks for the same general timeframe.
Unlike a private model run, NOAA’s Climate Prediction Center outlook represents an official consensus forecast, giving residents across the highlighted region added confidence that a genuine shift toward cooler, more fall-like conditions could be on the way by mid-September.
Highs in the 70s and Lows in the 50s Possible Across the Region
For a region that has dealt with a notably hot summer, the prospect of highs in the 70s and lows in the 50s represents a meaningful change in feel, even if it does not amount to a dramatic cold snap. That kind of temperature range is broadly consistent with typical mid-September conditions across the Upper Midwest, meaning this outlook essentially points toward a return to seasonal normalcy rather than an unusually cold pattern.
For residents who have spent much of the summer dealing with above-normal heat, even a return to average temperatures could feel like a welcome taste of fall after an extended stretch of unusually warm conditions.
Below Normal Temperatures Also Target New England
Beyond the Upper Midwest and Great Lakes, NOAA’s outlook also highlights a separate area of below-normal temperatures across parts of New England, including Maine and portions of the surrounding region. This second below-normal zone, disconnected from the main Midwest signal, suggests the same broader pattern shift could bring cooler conditions to more than one part of the country during the same outlook window.
Communities across both highlighted zones, the Upper Midwest and Great Lakes as well as New England, should watch for a cooler-than-typical stretch as mid-September approaches, even though the two areas are separated by a swath of near-normal territory in between.
Near Normal Conditions Split the Cooler North From a Warmer South
Between the below-normal zones and the warmer conditions expected farther south, a band of near-normal temperatures stretches across parts of the Pacific Northwest, the northern Rockies, and a corridor running through the Mid-Atlantic and interior Northeast. This transition zone represents the area where confidence is lowest in either an above or below-normal outcome, essentially marking the boundary between the cooler and warmer signals on either side.
Communities within this near-normal band should expect temperatures closer to typical mid-September averages, without a strong lean toward either an unusually warm or unusually cool outcome during the outlook period.
Above Normal Warmth Persists From the Southwest to Florida
While the Upper Midwest and New England trend cooler, much of the rest of the country is expected to stay warmer than normal, with the strongest above-normal signal stretching from the Southwest through Texas, the Gulf Coast and into Florida. The West Coast, Alaska and Hawaii are also included in this above-normal category, reflecting a broad warm signal across much of the western and southern United States during the same window.
Florida in particular stands out with one of the higher probability readings for above-normal temperatures on the entire map, suggesting residents there should expect little relief from warm conditions even as parts of the Midwest and New England trend cooler.
How This Compares to Earlier Long Range Outlooks
This official NOAA outlook lines up closely with private long-range forecasts issued in recent days pointing to a cooler pattern developing across the Midwest and Great Lakes around the same September 16 to 22 window. The convergence between an official government outlook and independent private forecasting adds meaningful confidence to the overall signal, even though some details, like the exact magnitude of the cooldown, can still vary between different outlook sources.
What an 8 to 14 Day Outlook Can and Can’t Tell You
It is worth remembering that an 8 to 14 day outlook like this one communicates probability rather than certainty, showing which direction temperatures are more likely to lean rather than predicting specific daily conditions. Even within a below-normal zone, individual days could still see near or slightly above-normal temperatures, and the outlook will continue to be updated as the September 16 window approaches and more current data becomes available.
