April is finally here! After a turbulent end to March, will this trend continue as we start heading into the peak of severe weather season? Here’s a look at the current temperature and precipitation outlooks for the 4th month of 2022!
The latest observations and model guidance are calling for a relatively warm April across the southern Plains, southeastern U.S., and up into New England. The highest chance for above-average warmth this month is across the southern Plains in Texas and New Mexico. Southern Florida also has a bit higher chance for above-average temperatures in April compared to the rest of the Lower 48.
The overall pattern favors warm temperatures across the Gulf Coast, Southeast, and Mid-Atlantic regions, but confidence is not as high. This is due to the lack of confidence in the exact positioning of upper-level ridging (high pressure) and troughing (low pressure).
Northwest Arkansas and River Valley are favored to see overall above-average temperatures in April. The cooler-than-average weather is expected to stay in the Pacific Northwest near Washington, Idaho, and Oregon.
April showers bring May flowers, right? Well, the overall pattern for April is expected to bring more showery weather than normal to parts of the Great Lakes and Pacific Northwest.
The expected Jet Stream pattern this month favors a drier than normal April for Desert Southwest and Southern Plains.
Northwest Arkansas and the River Valley are in the neutral zone between the above-average and below-average precipitation areas. This means we have an equal chance to see above-average precipitation or below-average precipitation throughout the month.

1981-2010 Climate Normals vs. 1991-2020 Climate Normals
Earlier last year, the National Weather Service updated the statistics used to calculate climate normals for a location. Generally, this happens on years that end with a 1 (example: 2001, 2011, 2021, etc.).
Why every 10 years? Updating the numbers every year could lead to skewed data, especially if the site is only a few years old. By doing updates every 10 years, it ensures the value is more representative of the site’s actual climate instead of being potentially altered drastically by a single historical event.
So, what’s changed with the most recent update for April? Let’s find out!
