Impact Day issued ahead of Sunday's severe weather threat
HUNTSVILLE, Ala. (WHNT) — If you have outdoor plans this Memorial Day Weekend, make sure you are staying weather-aware as storms will be possible during the afternoon and evening hours.
The Weather Authority has issued an Impact Day for Sunday from 12 pm until 7 pm due to the threat of strong to severe storms. This storm threat will be associated with a mesoscale convective system, or MCS, that will track southeast into the area from Arkansas.
The Storm Prediction Center has highlighted the area under a 'Slight Risk' (level 2 out of 5) for the development of strong to severe storms.
Following lingering showers and isolated storms Saturday night, the area looks to turn dry early Sunday morning. IF we see a lack of rain activity Sunday morning, it will increase the energy for afternoon storms during the afternoon.

The MCS will begin to enter NW Alabama by midday and then push southeast through the Tennessee Valley. Embedded in the cluster of storms, there will be a chance for isolated strong to severe storms. That storm threat will continue through the early evening hours.
The MCS will form in Arkansas and then move into the Tennessee Valley. An MCS is a complex of storms on a larger scale that can travel for miles. The formation can be linear or round. The system that will move through the area Sunday will be round in formation as it tracks into NW Alabama before breaking down into a line segment.
Storms that can develop on Sunday will be able to produce damaging winds over 50 mph, large hail, frequent lightning, and heavy rainfall. With high values of wind shear, or rotation of the winds, there will be a low-end risk of tornadoes, especially in NW Alabama.
If you have outdoor plans, you must have multiple ways to receive weather alerts and be weather-aware. Stick with The Weather Authority for the latest on Sunday's storm threat.

Weather Blog: Weekend Outlook
FAYETTEVILLE, Ark. (KNWA/KFTA)— With a rainy weekend last week, will we have another Seattle-like weekend? This Weather Blog has the answers! Tomorrow will be a FANTASTIC Friday. After a system has pushed through Thursday, high pressure will fill in, clearing the skies for a bright and sunny day across Northwest Arkansas and the River Valley. Morning lows will be in the mid-50s, and high temperatures will reach around the mid-to-upper 70s. Winds will be out of the North to Northwest throughout the day at 5-10 mph with gusts up to 15 mph. Skies will start off with plenty of sun, but by the afternoon, high clouds will roll in, accompanied by some low and mid-level clouds that will increase in the evening. Overnight Saturday into Sunday, a few showers and storms are expected at times from 10 pm until 5 am Sunday. There is no severe weather threat at this time. Temperatures in the morning will hover in the mid-to-upper 50s, with high temperatures between 71-76°. Winds will likely be out of the West to Northwest around 5-10 mph. The radar should be quiet by sunrise, however, there will be mostly cloudy skies in the morning, turning into partly cloudy by midday.

Wet and stormy 2nd half of May brings beneficial moisture
ST. JOSEPH, Mo. (News-Press NOW) — Recent weeks have brought beneficial rains across the Mid-Missouri River Valley, watering soils and keeping new vegetation lush and green. May got off to a dry start locally and regionally, with over two weeks of little to no precipitation and above-average temperatures. From May 1 to May 17, only a trace of rain fell in St. Joseph, allowing moderate drought conditions to expand into much of Northwest Missouri and Northeast Kansas. Nearly two weeks later, the May rainfall deficit has almost disappeared completely, thanks to a wet and stormy pattern. As of 2:00 p.m. on Thursday, May 29, 2025, a total of 4.31 inches of rain has been recorded at St. Joseph's Rosecrans Memorial Airport, just shy of the monthly average of 4.87 inches. In a 24-hour period on May 18–19, 2.72 inches of rain fell — more than half of both the current monthly total and the average. Subsequent bouts of slow and steady rain that made for a less than ideal Memorial Day Weekend added just under 2 inches of additional rainfall to the total. Water levels on the Missouri River and other local waterways have recovered considerably after recent rains, after falling below normal earlier this month. The Missouri River has risen by several feet at the downtown St. Joseph gauge, from its low point of 5.6 feet on May 16, to a high point of 8 feet by May 23rd. As of May 29, levels have settled to around 7.6 feet — a normal figure for this time of year. Aside from river levels, soil moisture and drought conditions have also improved from recent rains. Halfway through May, almost 7% of Missouri was in Moderate drought, — this included the majority of Northwest Missouri from Interstate 35 westward to the Kansas border. As of May 27, that figure is down to 3% with a small patch of moderate drought still present in Holt, and parts of Nodaway and Atchison counties. According to the Climate Prediction Center's extended outlook, the next 6 to 14 days is likely to bring near to just above average precipitation across the Central Plains. A pattern that will likely keep widespread drought development at bay as the first month of meteorological summer begins.
