Spring, Early Summer Outlook: West, Plains Heat Builds, But Not As Much Into Northeast
Spring and early summer are showing trends in forecasts of both temperatures and precipitation across the U.S., according to an April through June outlook issued by The Weather Company and Atmospheric G2.
(MORE: How Average Temperatures Rise Through Spring)
The Southern Plains and Southwest are expected to have a hotter than usual spring and early summer, particularly the southern Rockies.
That said an overall warm spring and early summer is expected over much of the country from the Northern Plains to the Mississippi Valley and Southeast.
Parts of the Northeast and Northwest, however, may not see as much unusual warmth by spring and early summer standards.
This outlook is an overall three-month trend. We will likely see periods that are warmer or colder in each respective region of the country when compared to what is shown in the map below.
April
The first full month of astronomical spring is expected to be hottest from Utah and Arizona to the lower Mississippi Valley. That includes Dallas, Denver, Houston and Phoenix.
Parts of the Northeast, Great Lakes and Northwest may skew a little cooler than average. That includes Detroit, New York and Seattle.
This somewhat cooler Northeast outlook is due to the orientation of a global pattern of rainfall and dry weather near the equator called the Madden-Julian oscillation that could force cooler air from Canada southward, according to Todd Crawford, Vice President of Meteorology at Atmospheric G2.
May-June
You may notice that May's temperature map below has a similar overall shape as April's. Perhaps skewing a bit cooler than average in the Northeast, Great Lakes and Northwest, while hotter than usual in the Southwest, Plains and Southeast.
But scroll down to the June map, and you'll notice some significant changes.
First, most of the country is expected to be hotter than average in June.
Compared to May, the most above-average heat is expected to expand northward into the upper Midwest, Northern Plains and northern Rockies, but not as much into the Southeast.

The Staggering Price Of US Hurricanes Since 2016: Over $800 Billion
The 2025 Atlantic hurricane season is beginning, following the costliest nine-year siege of hurricanes and tropical storms in the U.S. that claimed over 4,000 lives. - Beginning with Hurricane Matthew in 2016 and ending with Hurricane Milton in 2024, a siege of 29 tropical storms and hurricanes over nine years caused at least $1 billion in damage in the U.S., according to statistics compiled by NOAA's National Centers for Environmental Information. - The total damage in the U.S. from these 29 storms was estimated at $820 billion, the costliest nine-year stretch for tropical cyclones in the U.S. dating to 1980. That's more than the 2023 gross domestic product of Poland. - These 29 storms claimed 4,026 lives in the U.S. from elements directly related to each storm's flooding and winds. The large majority of those deaths were in Puerto Rico from 2017's Hurricane Maria (2,981), though two recent hurricanes - Helene (219 killed) and Ian (152 killed) - also claimed over 100 lives each. (MORE: Helene, Milton Among Most Recent Hurricane Names Retired) - In that same nine-year stretch, six of the 10 costliest U.S. hurricanes have occurred. - Three of those - Ida ($85 billion), Ian ($120 billion) and Helene ($79 billion) - have occurred in the past four years. The other three - Harvey ($160 billion), Irma ($64 billion) and Maria ($115 billion) each occurred in 2017. - NOAA's database lists 67 U.S. billion-dollar-plus tropical storms and hurricanes since 1980. - But these events don't happen every year. Before 2016, the U.S. went three straight years without a billion-dollar tropical storm or hurricane following Superstorm Sandy. There were also two-year stretches without these particularly costly storms after the 2008 and historic 2005 hurricane seasons. (MORE: When Was The Last 'Quiet' Hurricane Season?) - Outlooks from Colorado State University, The Weather Company/Atmospheric G2 and NOAA are each calling for a more active than average 2025 hurricane season, but not as active as 2024. - "Since 1950, 23% of all North Atlantic hurricanes have made landfall in the U.S.," wrote Todd Crawford, Vice President of Meteorology at Atmospheric G2 in an earlier outlook. NOAA's Hurricane Research Division calculated an average of about one hurricane made landfall in the U.S. each year, based on data from 1851 through 2022. - Crawford's team noted long-range computer models suggest the pattern of winds aloft that guide hurricanes could steer them more toward the U.S. again in 2025. - It's too soon to tell whether that pattern will be in place while a hurricane is out there this season. For now, the AG2/TWC team is forecasting three hurricanes to make a U.S. landfall in 2025, two less than did so during the destructive 2024 hurricane season. Now – not in the days before a hurricane strikes – is a good time to refresh or develop a plan.

Tropical outlook quiet to start Atlantic hurricane season, but there may be a window for potential
As June ushers in the official start of the Atlantic basin hurricane season, attention is once again turning to the tropics in search of the first signs of development. Similar to patterns observed over the past three years, the season is expected to begin on a quiet note, with no named storms forecast to form in the opening days of the month. However, the big question is whether the rest of June will follow suit. To help answer that question, forecasters often consult a variety of products, including tracking what is known as the Madden-Julian Oscillation, or what is commonly called the MJO. This eastward-moving pulse of enhanced rainfall and lower atmospheric pressure typically circles the globe every 30 to 60 days and can significantly influence tropical weather patterns. The Mjo is divided into eight phases, each affecting different regions of the globe. When the MJO is in phases 8, 1 or 2, it generally leads to enhanced activity over the Atlantic basin and, if other conditions align, can increase the chances of tropical cyclone formation. Pattern Emerges In Tropics For First Time In More Than 20 Years Because of the MJO's current location and timing, forecasters expect only one favorable window for development in the Atlantic basin during June. This period is likely to occur in the second half of the month, and the Caribbean and the Gulf are the most probable areas of interest. This region is climatologically favored for development due to the presence of features that can aid in the formation of tropical cyclones, such as old frontal boundaries or the Central American Gyre, a large area of lower pressure. The latest outlook from NOAA's Climate Prediction Center points to a potentially favorable environment for tropical development during weeks two and three of the month. While the outlook does not guarantee a named storm will form, it will lead to increased tropical moisture over Central America, Mexico, and possibly as far north as the Gulf Coast. By late June and early July, atmospheric conditions may again become less conducive to development as the MJO continues its eastward progression around the globe. 2025 Atlantic Hurricane Season Guide: Here's What To Know About The Tropics This Year The formation date of the season's first named storm can be an important indicator of what's to come. Statistically, when the first named storm forms before June 20, it often signals a more active season ahead. On the other hand, if the season reaches early July without a named storm, it may serve as an indicator of a quieter-than-average year. The last time the first named storm formed on or after June 20 was in 2014, when Arthur developed on July 1. The year ended up being relatively subdued, with only eight named storms, six hurricanes and two major hurricanes - all well below the seasonal averages. Although the Atlantic hurricane season officially runs from June 1 to November 30, losing the entire first month to inactivity effectively removes more than 16% of the season's duration. This lost time cannot be regained later in the year, as water temperatures typically decline and atmospheric stability increases, making storm formation less likely. So, while the start of the 2025 hurricane season appears tranquil, forecasters will be closely monitoring the MJO and other key indicators in the coming weeks for any early hints of article source: Tropical outlook quiet to start Atlantic hurricane season, but there may be a window for potential

When Could The Atlantic Hurricane Season's First Storm Form?
The 2025 Atlantic hurricane season "officially" arrives soon, and we're getting some hints as to when we might see the first tropical storm of the season form. - We could see the season's first storm, named "Andrea", form as soon as the middle of June. - That's because some long-range computer models suggest the tropical Atlantic Basin may come under the influence of rising air and lower wind shear from something called the Madden-Julian Oscillation. That's an environment supportive of thunderstorms, which are the building blocks of tropical storms. - It's far too soon to be certain this will occur and where, but tropical development in June usually happens either in the western Caribbean Sea, Gulf of Mexico, or off the Southeast U.S. coast. (MORE: 2025 Atlantic Hurricane Season Outlook) - In the satellite era, the season's first storm has developed most often in June. From 1966 through 2024, the average date of the first storm of hurricane season is June 10. - Last year, Tropical Storm Alberto formed in the western Gulf on June 17. - But as the graph below shows, there's considerable spread, especially recently. Only two of the past 10 hurricane seasons have had the first storm form in June. Five of those 10 years have had a May storm, including four straight years from 2018 through 2021. (MORE: 2025 Atlantic Hurricane Season Name List Includes One Newby) - Occasionally, these first storms of the season can be impactful, especially given that they typically form closer to land early in the season. - Last June, Tropical Storm Alberto produced flooding rain and 1 to 4 feet of storm surge along the coast of northeast Mexico and Texas. - In 2010, Alex quickly strengthened from a late June tropical storm to a Category 2 hurricane before slamming into northeast Mexico with a surge, up to 35 inches of flooding rain and damaging winds. Now – not in the days before a hurricane strikes – is a good time to refresh or develop a plan. That includes knowing if you live in an evacuation zone, assembling a disaster kit at home, making your home as resilient as possible, checking on your insurance policy and making an inventory of your belongings.
