Weather Authority Impact Day issued for Tuesday's severe storm threat
HUNTSVILLE, Ala. (WHNT) — While isolated storms will be possible Sunday and Monday across the Tennessee Valley, a more potent storm system is forecast to track through the area Tuesday into Wednesday.
Ahead of a widespread threat of strong to severe storms, The Weather Authority has issued an Impact Day from Tuesday afternoon into early Wednesday morning.
Storms that can develop will be capable of producing damaging winds, large hail, frequent lightning, and tornadoes. Outside of storms, winds will also be on the stronger side. Gusts between 25 to 30 mph will be possible.
A potent storm system is forecast to move into the region, leading to a warm front passage. This warm front passage will allow for the increase of warm and moisture into the region.
The Tennessee Valley will also be placed in an area between the cold and warm fronts known as the 'warm sector'. This sector will have all the ingredients present to support the widespread coverage of strong to severe storms.
The Storm Prediction Center has the area for a 30% or greater chance of a severe storm to form within 25 miles of the area highlighted in orange.
Ahead of Tuesday's widespread strong to severe storm impact, multiple disturbances tracking through the area will support the chance of isolated thunderstorms.
The rain chance will not be widespread, and this period is not expected to be a complete washout. This being said, isolated strong to severe storms will be possible. If these storms can develop they will be capable of producing strong winds, heavy rain, and hail.

It has never rained on June 11 in Phoenix. Could it happen this year? Here's what to know
Metro Phoenix's dry summer weather isn't surprising. However, residents may be shocked to know that there is one day it has never rained — June 11. Since the National Weather Service began keeping records nearly 130 years ago, Phoenix has only seen trace amounts of rain, meaning the moisture was so light that it was not measurable, according to meteorologist Mark O'Malley. That was in 1991. There are also two other dates — May 30 and June 16 — where just 0.01 inch of rain has fallen, O'Malley confirmed. Why is that? It's because June is the driest month in Phoenix. Here's why metro Phoenix sees such dry weather in June and what to expect this week. June is the driest month for metro Phoenix, O'Malley said. On average, only 0.02 inches of rain falls during the whole month. Most years, including 2023 and 2019, no rain falls during June. "Just to get rain on any single day is an uncommon occurrence," he said. This year, an early June storm system dumped more than an inch of rain around the northern reaches of metro Phoenix, hinting at more moisture ahead than the Valley has seen over recent summers. "The first part of monsoon is not as wet as later in the monsoon," O'Malley said. "You have to pull in a lot more moisture. For Phoenix specifically, we don't start to see thunderstorms due to monsoon until about the beginning of July." News alerts in your inbox: Don't miss the important news of the day.

"We're looking for seasonably warm conditions with high temperatures in metro Phoenix of 105 to 110 degrees and then getting hotter over the weekend," he said. Here is the weather forecast for Phoenix Sky Harbor International Airport, the official weather station, according to the weather service: June 10: Sunny during the day, with a high near 106. Light and variable wind becoming west 5 to 10 mph in the afternoon. Mostly clear at night, with a low around 81. West wind around 5 mph becoming calm after midnight. June 11: Sunny during the day, with a high near 107. Light southwest wind becoming west 5 to 10 mph in the afternoon. Clear at night, with a low around 81. West wind 5 to 10 mph becoming light west southwest after midnight. June 12: Sunny during the day, with a high near 108. Light and variable wind becoming west 5 to 10 mph in the afternoon. Mostly clear at night, with a low around 81. West southwest wind 5 to 10 mph becoming light and variable after midnight. June 13: Sunny during the day, with a high near 107. Calm wind becoming southwest around 5 mph in the afternoon. Mostly clear at night, with a low around 81. West wind around 5 mph becoming calm after midnight. June 14: Sunny during the day, with a high near 109. Calm wind becoming west around 5 mph in the afternoon. Mostly clear at night, with a low around 82. West wind around 5 mph becoming calm in the evening. June 15: Sunny and hot during the day, with a high near 111. Calm wind becoming west around 5 mph in the afternoon.

Northern Lights Alert: Aurora Borealis May Appear In These 8 States Tuesday
A selection of states in the northern U.S. may have an opportunity to view the northern lights Tuesday, as auroral activity is expected to be calmer through the week, according to the National Oceanic and Atmospheric Administration. Auroral activity will likely be calmer through the week, forecasters said. Auroral activity is forecast with a Kp index of three on a scale of nine for Tuesday night, indicating the northern lights will be visible farther from the poles and could be 'quite pleasing to look at' for anyone in the right areas. No geomagnetic storms or increased solar radiation are expected through Thursday night, NOAA's projections suggest, after earlier coronal mass ejections created 'minor' storms that pulled the northern lights to more states. Tuesday night's forecast is the strongest over the next two days, with a maximum Kp index of two projected for Wednesday and Thursday, according to NOAA's three-day forecast. A view line marking a minimal opportunity of viewing the aurora borealis is forecast just south of the Canadian border, with a lesser chance projected for parts of northeastern Washington, northern Idaho, Montana, North Dakota, northern Minnesota, northern Wisconsin and Upper Michigan. Most of Canada and Alaska have a higher chance. (See map below.) Tuesday's view line. NOAA suggests traveling between 10 p.m. and 2 a.m. local time to an unobstructed, north-facing and high vantage point away from light pollution to see the northern lights. NASA recommends enabling night mode, disabling flash and selecting a slower shutter speed if using a smartphone. With a regular camera, the agency suggests using a tripod to stabilize the image, a wide-angle lens, an aperture or F-stop of four or less and a focus set to the furthest possible setting. More people in the U.S. have had opportunities to see the aurora borealis over the last year, after activity on the sun's surface reached a 'solar maximum.' This peak, which marks an increase in solar events like solar flares and coronal mass ejections, occurs periodically during the sun's 11-year cycle. Electrons from these events are responsible for the northern lights, as they release energy in the form of colorful, swirling lights after colliding with oxygen and nitrogen in the Earth's atmosphere.

Getting A Small Breather From the Rain
After a round of stronger storms on Monday, we get a breather from stormy conditions over the next few days. Here is a look at the last 24 hours. We are at 0.50″ at Huntsville International almost two weeks into June. Futurecast is quiet through the middle of the week. We have drier air behind a cold front. After some early morning showers Tuesday, we are free and clear for awhile. You can get out and mow the grass later today. Father's Day weekend could turn a little more stormy for the Tennessee Valley. We will have more updates as we get closer to the weekend. Stay with the Weather Authority!
