The Alaska statewide July temperature was 52.8°F, 0.1°F above the long-term average, ranking in the middle third of the 100-year period of record for the state. Near-average temperatures were observed throughout most of the state, with above-average temperatures observed across much of the Northeast Gulf, Aleutians and South Panhandle.

Billion-dollar disasters
Four new billion-dollar weather and climate disasters were confirmed in July 2024, including one severe weather event that impacted the southern U.S. in mid-May, New Mexico wildfires during June and July, one severe weather event that impacted the central and northeastern U.S. (June 24–26) and Hurricane Beryl (July 8–9).
Through July 2024, the United States has experienced 19 disasters totaling at least 1 billion dollars in damages. NOAA image from National Centers for Environmental Information.
There have been 19 confirmed weather and climate disaster events this year, which is second only to 2023 for the highest amount for the first seven months of the year, each with losses exceeding $1 billion. These disasters consisted of 15 severe storm events, one tropical cyclone event, one wildfire event and two winter storms. The total cost of these events exceeds $49.6 billion, and they have resulted in at least 149 fatalities.
The U.S. has sustained 395 separate weather and climate disasters since 1980 where overall damages/costs reached or exceeded $1 billion (including CPI adjustment to 2024). The total cost of these 395 events exceeds $2.770 trillion.
Other Notable Events

Drought
According to the July 30 U.S. Drought Monitor report, about 20% of the contiguous U.S. was in drought, up a little over 1% from the end of June. Drought or abnormally dry conditions expanded or intensified this month across much of the West and Hawaii, and parts of the Central and Northern Plains, the Ohio Valley, the central Appalachians, Tennessee and the Northeast. Drought contracted or was reduced in intensity across much of the Southeast, western portions of the Ohio Valley and parts of Arkansas and Texas.

Although not officially in drought, a sizeable part of the country was abnormally dry (yellow), including most of the West and along an arc tracing out the Southern and Central Appalachian Mountains from Alabama to Pennsylvania.

Monthly Outlook
Above-average temperatures are favored to impact areas across the western and southeastern portions of the U.S. in August, while below-average precipitation is likely to occur in the Northwest and south-central Plains. Drought is likely to persist in the Northwest, Central Plains and Hawaii. See Mike Halpert's post about the Climate Prediction Center's U.S. climate outlook for August 2024.
