Impact Day Tuesday: Threat of strong winds & severe storms
HUNTSVILLE, Ala. (WHNT) — The Weather Authority has been monitoring the fire threat throughout the weekend, but heading into next week, all eyes turn on a severe weather threat.
The team has issued an Impact Day for Tuesday due to the threat of damaging winds and storms.
The Weather Authority implements new Impact Day during Severe Weather Awareness Week
Impact Days are issued for any impactful weather which could range from extreme heat and extreme cold to organized severe storms and tornadoes. We won't hype the forecast but rather inform you about days when the weather will impact your day-to-day.
The Impact Day was issued due to the threat of strong to severe storm development along a cold front. Along with the threat of storms, strong winds with gusts of 40-50 mph will be possible outside of any storms that develop.
Alabama Forestry Commission continues Wildfire Advisory into Sunday
When strong cold fronts form, it leads to tight pressure gradients. The tighter the pressure gradient, the stronger the winds are here at the surface.
Isolated rain showers will be possible early Tuesday morning but the greatest threat of storms for the area will arrive by the evening.
At this vantage point, a line of rain with embedded storms will enter Northwest Alabama around 4 p.m. just in time for the evening commute. This line will then track eastward through the area reaching the Huntsville metro by 7 p.m. Storms will move out of Northeast Alabama between 10 and 11 p.m.
It's important to note that the timing is subject to change as we continue to analyze model data ahead of the event.
There's already a risk outlook from the Storm Prediction Center, highlighting the threat. The SPC has highlighted a higher risk west of the area along the Mississippi River where the environment is more supportive for severe storms.
Storms that can develop will be capable of producing damaging winds over 60 mph. heavy rainfall, frequent lightning, and even a tornado. The tornado threat is present because of high values of wind shear, or rotation in the winds.

Rainy week ahead in Northwest Arkansas, River Valley: Here's what to know
FAYETTEVILLE, Ark. (KNWA/KFTA) — An active pattern brings several chances for rain across the region throughout the week. A straight west-to-east upper-level flow, known as zonal flow, brings multiple 'shots' of upper-level lift, which in turn bring rain chances for several days this week. In the early morning, there's a good chance some showers could clip northeast Oklahoma and southwest Missouri. So, mostly cloudy skies are expected to start, but by early afternoon, skies will start to cloud up, with rain chances dramatically increasing in the evening around 8 p.m. Severe weather is in the forecast, with the main threat being strong winds and hail. This subtle flow weather pattern could bring a few light showers early in the morning. By midday, some more showers and storms are expected. We are still a ways out, so some timing and coverage will change. More shortwave troughs move in to bring rain and storms throughout the day. Through Saturday, 1-3 inches of rain are expected with locally higher amounts of 3-5″ possible. Almost every day, there will be some rain in our weather coverage area.
