Tennessee Heat Break Expected Starting Sept. 23

Tennessee Heat Break Expected Starting Sept. 23

Tennessee has been experiencing sweltering heat under an oppressive heat dome, with temperatures remaining above normal throughout September. According to the National Weather Service, a slight break in the heat is expected starting September 23, coinciding with the astronomical start of fall on September 22. Memphis, Nashville, and Knoxville will see daytime highs drop slightly, with Memphis reaching 92°F (33.3°C) on September 22 and Knoxville seeing highs of 83°F (28.3°C) on September 23. Despite this brief relief, temperatures are forecast to remain above average for the remainder of the month, with more significant cooling anticipated in October. Meteorological fall began on September 1, but the state has yet to experience sustained cooler weather. The heat dome, characterized by high humidity, limited cloud cover, and light winds, has intensified the discomfort across the region.

Houston to See Highs Near 96°F on September 22

Houston to See Highs Near 96°F on September 22

The National Weather Service and ensemble forecasts predict a high temperature of approximately 96°F (35.6°C) in Houston, Texas, on September 22, 2026. Sunny skies and light northeast winds are expected, with heat indices reaching up to 105°F (40.6°C). This weather pattern is attributed to persistent subtropical ridging and moisture advection from the Gulf. While the forecasted high is above the September average of 88–90°F (31–32°C), it remains below the late-month record highs of 99–108°F (37–42°C).

Miami's Low Temp on Sep. 22 Predicted at 76–79°F

Miami's Low Temp on Sep. 22 Predicted at 76–79°F

The National Weather Service and model consensus predict that the lowest temperature in Miami on September 22, 2026, will range between 76–79°F (24–26°C). This forecast aligns with a 68.5% implied probability for this range, as indicated by market predictions. Persistent subtropical ridging, light easterly winds, and warm Gulf Stream waters near 86°F (30°C) are contributing to limited overnight cooling and maintaining typical late-summer humidity. Ensemble models show minimal variability, with a slight chance of temperatures trending lower. The forecast is based on data from NOAA and Weather Underground, with final confirmation expected after the observation date.

Dallas Forecast: Highs in Low-to-Mid 90s on Sep. 22

Dallas Forecast: Highs in Low-to-Mid 90s on Sep. 22

The National Weather Service and model consensus predict a mostly sunny day in Dallas, Texas, on September 22, 2026. High temperatures are expected to range from the low-to-mid 90s °F (approximately 32-35 °C), slightly above the historical late-September average of 88°F (31°C). A recent frontal passage will bring cooler and drier air to the region, limiting afternoon heating compared to previous days dominated by southerly flow. Northeast winds will accompany the cooler air mass, contributing to a pleasant weather pattern for the day.

Los Angeles Overnight Lows to Hit Mid-60s on Sep. 22

Los Angeles Overnight Lows to Hit Mid-60s on Sep. 22

According to recent guidance from the National Weather Service and weather models, overnight temperatures in Los Angeles on September 22, 2026, are expected to range between 63°F and 67°F (17°C to 19°C). This forecast is attributed to a persistent marine layer and moderate onshore flow from the Pacific Ocean, which will limit radiative cooling. The predicted temperatures align closely with the late-September climatological average low of 62.8°F (17.1°C) for the area. No significant deviations from this range are anticipated, as there are no indications of strong offshore winds or unusual warming patterns during this period.

Rain Likely in Boston on September 21, 2026

Rain Likely in Boston on September 21, 2026

According to the National Weather Service (NWS) and the NWS Daily Climate Report (CLI), there is a possibility of measurable precipitation in Boston, MA, on September 21, 2026. Measurable precipitation is defined as 0.01 inches or more of liquid-equivalent rainfall. The observation period for this forecast is from midnight to midnight local standard time. The final determination of whether measurable precipitation occurs will be based on the NWS CLI report, which is expected to be published by 2:00 PM ET on September 22, 2026. This forecast is part of a broader weather pattern influenced by a stalled frontal boundary and a surge of moisture over the eastern and central United States, which is expected to bring scattered showers and thunderstorms to the mid-Atlantic and Northeast regions.

Seattle's Low Temp on Sep 22 Expected in Mid-50s°F

Seattle's Low Temp on Sep 22 Expected in Mid-50s°F

Forecast models from the National Weather Service (NWS) predict that the minimum temperature in Seattle on September 22, 2026, will likely fall in the mid-50s°F (approximately 12-14°C). This range aligns with market-implied probabilities for temperatures between 54°F and 57°F. Light winds, high pressure aloft, and partly cloudy skies are expected to contribute to moderate radiational cooling overnight. However, elevated dew points near 50-52°F and residual low-level moisture from marine air are likely to limit further temperature drops. These conditions are typical for late September in the region, as noted in recent NWS discussions. [Source time: not specified]

Arizona Fall Forecast: Above-Average Rain Expected

Arizona Fall Forecast: Above-Average Rain Expected

As Arizona transitions into fall, weather forecasts from the National Weather Service (NWS), AccuWeather, and The Old Farmer's Almanac present varying predictions for the season. The fall equinox begins on Tuesday, September 22, 2026. According to the NWS, Arizona has a 33% to 40% probability of experiencing above-average temperatures statewide, while AccuWeather predicts temperatures will be one to two degrees below historical averages in some areas, with southern cities like Sierra Vista and Nogales expected to remain at historical norms. Rainfall predictions also differ, with the NWS and AccuWeather forecasting above-average precipitation, particularly in September, when rainfall could reach 125% to 149% above normal. In contrast, The Old Farmer's Almanac anticipates a drier-than-usual fall for most of the state, except for northern-central areas like Sedona, which may see increased precipitation.
