ALT The Days 8-14 U.S. Hazards Outlook, valid for the period of Jun 18-24, 2026 from the Climate Prediction Center. A 40-60 percent chance of Extreme Heat is indicated over much of the Florida Peninsula including Miami, Jun 18-22, where heat index values may exceed 105 deg F. In addition, little overnight relief is expected with record high minimum temperatures possible.

ALT The first heat wave of the season will impact much of the country to the east of the Rockies by next week with the Central and Southern Plains being the first to see impacts, followed by the east coast by the second half of the week. High temperatures will be several degrees above normal with increasing humidity leading to excessive heat for a large portion of the U.S.

ALT The Climate Prediction Center’s 6-10 Day Precipitation Outlook issued May 26, 2026, valid June 1-5, depicts an increased chance of above-normal precipitation across Florida, with the largest probabilities (60 to 70 percent) for Central Florida and greater than a 50 percent chance of above-normal precipitation for much of the state.

ALT The U.S. Drought Monitor, valid May 19, depicts a 74.61% coverage of extreme (D3) to exceptional (D4) drought for Florida.

ALT The Climate Prediction Center indicates a moderate risk (40 to 60 percent chance) of heavy precipitation across portions of eastern Texas, southeastern Oklahoma, and into the Lower Mississippi Valley, May 23 to24. A broader slight risk (20 to 40 percent chance) includes more of the Southern Plains in addition to portions of the Tennessee Valley and Southeast, and is valid through May 25. Enhanced southerly flow from the Gulf favors increasing chances of heavy precipitation, along with localized river and flash flooding, beginning next week and continuing into the Memorial Day holiday weekend.

ALT The Climate Prediction Center indicates a moderate risk (40-60 percent) of extreme heat over much of the Central and Southern High Plains region, May 13-14. A slight risk (20-40 percent) of extreme heat is valid for a broader portion of the Central and Southern Plains, and extends through May 15. Temperatures are expected to climb into the upper 90’s to near 100 deg F during this time, with heat index values of 100-105 deg F. Mid-level ridging and low-level southerly flow are forecast to contribute to the extreme heat. Dry soils, hot temperatures, and gusty winds may elevate the risk of wildfires.

ALT The Climate Prediction Center’s Global Tropics Hazards Outlook issued on May 5 indicates a slight risk (20-40 percent chance) of Tropical Cyclone (TC) development in the general vicinity of Guam and the CNMI during week-2 (May 13-19). A high risk (greater than 60 percent chance) of TC development is favored in the same general region during week-3 (May 20-26). This is based largely on precipitation composites associated with the Madden-Julian Oscillation. Concerns would include very heavy rainfall, strong winds, storm surge, and serious flooding.

ALT The Risk of Extreme Heat, valid for the period of May 12-18, 2026, and the 6 to 10 day temperature outlook, valid for the period May 10-14, 2026, both from the Climate Prediction Center. A Moderate Risk of Extreme Heat is indicated over parts of the Desert Southwest, including Phoenix AZ. High temperatures may reach 110 degrees Fahrenheit for these areas May 11-12. A Moderate Risk of Extreme Heat is also indicated over the southern reaches of the Central Valley of California, including Fresno and Bakersfield, where high temperatures of 100 to 105 degrees Fahrenheit are possible. A broader Slight Risk of Extreme Heat covers the remainder of the Central Valley of California and Southwestern deserts, including Las Vegas NV, for high temperatures reaching well into the 90’s. Most of the slight and moderate risk areas have a greater than 70 percent chance of above-normal temperatures during May 10-14.

ALT The Climate Prediction Center’s 8 to 14 Day Hazards Outlook issued April 30 indicates a moderate risk (40 to 60 percent chance) of much below normal temperatures May 8 across much of the Midwest and Appalachians. A moderate risk (40 to 60 percent chance) of high winds is forecast across most of the East May 8 and May 9.

ALT The Climate Prediction Center Global Tropics Hazards Outlook released April 28, 2026 for the valid period of May 6, 2026 through May 12, 2026. A 40 to 60 percent chance of tropical cyclone formation is indicated for the Western Pacific east of the Marianas Islands; with a broader 20 to 40 percent chance surrounding it and extending eastward to near the Date Line.

ALT CPC Week 2 Hazards Outlook (left) issued Apr 24, 2026 for May 2-8, 2026 shows a moderate risk (40 to 60 percent chance) of much below-normal temperatures for parts of the Midwest, May 2-3. A broader slight risk (20 to 40 percent chance), May 2-4 covers much of the central and eastern CONUS excluding the Deep South.

ALT CPC’s 6-10 Day Temperature Outlook (right) issued the same day for April 30-May 4, 2026 shows most of the areas across the central and eastern CONUS (excluding the FL peninsula and northern Maine) with favored below normal temperatures. The greatest chances for this category is indicated for the Ohio Valley and Lower Great Lakes with a 60-70 percent chance).

ALT Climate Prediction Center 6-10 day Temperature Outlook depicts high probabilities (at least 80 percent) for above-normal temperatures across portions of the south-central U.S., Ohio and Tennessee Valleys, Central and Southern Appalachians, Mid-Atlantic, and Southeast during the 6-10 day period (April 15-19).

ALT Climate Prediction Center Week-2 Hazards Outlook depicts a moderate risk of hazardous much above normal temperatures across the Tennessee Valley and Southern Appalachians southward into Georgia and surrounding areas, April 17-18. A slight risk for hazardous much above normal temperatures extends westward into the Lower Mississippi Valley, also valid April 17-18. Areas of Rapid Onset Drought (ROD) are also noted across parts of the Southeast.
