April weather outlook: Severe storms target millions as spring temperature warmup finally nears
A dip in the jet stream is breaking down the Western heat wave and pushing warmth east—but as it clashes with cooler air, severe storms could fire up across the Plains.
They say "April showers bring May flowers"—but that’s only part of the story. This April could have a few twists of its own.
So, what really is in store for us around the country? The FOX Forecast Center is calling for a "big shake-up." From severe storms to warmups and cooldowns, let’s break it down.
As we move out of March — The old saying "March comes in like a lion and leaves like a lamb" has certainly come true in 2026, kicking off severe weather season in a big way — the pattern across the U.S. is about to shift, as a historic heat wave in the West will begin to ease and push east.
We saw over 30 tornadoes in the month of March, triggering massive devastation across the Heartland.
And now this warm, moist air, colliding with the cooler air already in place, will trigger severe storms across the Plains and into the Mississippi River Valley by the beginning of April.
As the record heat wave out west begins to ease, the pattern will shift and will break down the heat dome, allowing temperatures to ease back closer to normal.

From California to Colorado, temperatures have been scorching, triggering many record-breaking march heat.
The FOX Forecast Center said that this shift will open the door to Pacific storm systems to move in again.
More rounds of rain and even snow will likely return to the region.
While April is typically the snowiest month for parts of the Rockies, much of the West is coming off a winter of below-average snowfall, with snowpack levels at record lows.

Some snowfall is expected to be on the lighter side, but some higher elevations across the West have the better chance of seeing more, specifically within the Northern Rockies.
But any snowfall will help ease the snow drought.
Meanwhile, lower elevations are expected to get some moderate to heavy rain.
As the heat exits the West, it will shift east, as that same ridge of high pressure is expected to rebuild over the eastern half of the country.
This will set the stage for a stretch of above-average warmth along the East Coast.
This creates a classic spring pattern with warmer air across the East and cooler, more active weather in the West, but the Eastern region is still expected to get some of those classic "April showers."
The FOX Forecast Center said the two air masses — warm air across the East and cooler air across the West — is where "things get interesting."

This is where the threat of severe storms potentially comes in, as the zone from the Great Plains through the Mississippi Valley is expected to become the focus for active weather.
That is where cooler air coming out of the West will collide with warm, moisture-rich air surging north from the Gulf of America.
When those ingredients come together, it creates a favorable setup for storms and potentially severe weather.
Some of these storms could arrive as early as mid-next week.
Portions of Texas, Oklahoma, Louisiana, Arkansas, Mississippi, Tennessee, Oklahoma, Kansas, and Missouri are at a high level severe storm probability for April.
These storms are expected to bring strong winds to the region, large hail, with EF2+ tornadoes possible for the month of April.
