SEVERE WEATHER THIS EVENING: A cold front will move through the Valley around midnight. But before that we could see some severe weather in terms of large hail and damaging winds. The slight risk for severe weather does not include everyone in the Valley. Also good to note that there is not enough wind shear for the threat of tornadoes.
FRIDAY: Our next chance for strong to severe storms will be caused by another strong cold front. The timing on this one continues to change from model run to model run. As of right now it looks to move through during the later afternoon and evening. This will only increase our threat for severe weather slightly.
WEEKEND: Things are looking great for everyone in the Valley. All of the nasty weather will be out in time for the weekend.
Tuesday: We'll see a few isolated showers building up for this afternoon as southerly winds will send in warm, moist air to the Valley, creating unstable conditions. Another round of isolated showers will move in this evening due to a weak cold front that will slide into the Valley from the North, giving us a lifting mechanism to trigger these showers. A few showers could be associated with rumbles of thunder, but nothing will be severe. Temperatures will reach into the mid 70's today.
Wednesday: Warm, southerly air will continue to give us the chance of stray showers on Wednesday. The majority of us will be staying dry. Temperatures will be into the upper 70's. Overnight lows will dip into the mid 50's.
Thursday & Friday: A cold front will trigger in more scattered showers Thursday and Friday afternoon and overnight night hours. Some storm could turn strong. Gusty winds, small hail and frequent lightning is likely.
Easter Weekend: Higher pressure will build in from the North, decreasing cloud cover and allowing for sunny weather. Temperatures due to Northerly wind will dip us into the mid 60's for highs. The ground will still be soggy Saturday morning for all our Easter Egg Hunts, but rain showers will be gone from the forecast until we head into Monday of next week.
Lightning is both a beautiful and deadly phenomenon. Sunday night, a bolt of lightning hit a tree in the backyard of a Madison home, and through a series of unfortunate events managed to travel over 100 feet to the house.
After it struck the tree, lightning then jumped to this shed. It worked its way from one metal object to another, melting them as it went. It eventually was able to work its way over to the other side of the shed where it exited.
The bolt of lightning then went through a metal grid on the side of the shed, digging a trench all the way along to this tree. From there, it then exited on the other side of the tree, where it worked it's way up into a metal fence.
The lightning would travel a couple hundred feet along the fence that runs around the backyard, finally coming in contact with a metal gutter. Then it traveled its way up to some outside lighting, burning it up, traveled down the aluminum siding of the house before finally blowing out a satellite TV cable.
The lightning didn't stop outside. It traveled from the outside lighting to the light switch on the inside, burning it up severely. It also followed the satellite cable through the wall ultimately severely damaging and rendering the television completely useless.
The homeowner estimates that it did about ten thousand dollars in damages to his home and appliances.
TONIGHT: Things will remain quiet with mainly clear skies and lows in the 40s.
TUESDAY: There will be plenty of instability but there will be the lack of forcing. However if any showers can develop they may become storms if the timing turns our right. If any storms do form they would just be good rainmakers.
WEDNESDAY & THURSDAY: We will see the same type of set up with instability but lack of forcing. The atmosphere should be able to squeeze out a few showers but nothing substantial is possible.
FRIDAY NIGHT: This is our next good shot at some storms. A cold front will move through and create a line of showers and storms. Some of these storms could be on the stronger side.
CLEARING MONDAY: The worst is over as rain showers are pushing out of Northeast Alabama this morning. Shower activity should be done by 7 to 8 A.M., then we'll start to see a gradual decrease in cloud cover and decreasing winds, leading to more sunshine this afternoon. Temperatures will reach into the mid to upper 60's. Tonight we'll also see clear skies dipping us down into the mid 40's.
STRAY SHOWERS TUESDAY, WEDNESDAY & THURSDAY: A few showers with a couple rumbles of thunder will move in particularly West of I-65 for the middle of the workweek. The majority of us will stay dry. As southerly winds return, temperatures will reach into the mid 70's.
STRONG STORMS EXPECTED FRIDAY: A very strong cold front will move through the Valley Friday evening where we have the potential of picking up on strong thunderstorms. Temperatures will go from the upper 70's to the mid 60's from Friday to Saturday. Winds will be gusty with possible small hail.
THUNDERSTORMS TO START: Starting early Morning, before the sun comes up, we'll have a few heavy showers and thunderstorms come through the area. These will be non severe and drop maybe a quarter inch of rain. The cloud cover will give us a mild start on Monday, and we'll climb into the mid 60's for our afternoon highs. This will set us up for a very warm week.
WARMING TEMPERATURES: Temps will climb as we go into mid week. Thursday is looking to be the warms with highs in the mid 70's. The return of the warmth is also accompanied by a chance of showers mainly mid to late week. The heaviest of the showers expected to move through Friday into Saturday.
NO FREEZING TEMPS THIS WEEK: That's right! Our lows over the next 7 days will bee mild, bottoming out main in the upper 40's and 50's with a few exceptions.
LAST NIGHT OF FREEZE: Most of north Alabama and southern Tennessee are under a Freeze or Hard Freeze warning until early Sunday morning. Temperatures tonight are expected to drop below freezing, many locations will drop into the mid and upper 20's with a few locations staying just above 30.
WARM WEATHER RETURNS: We will experience a nice warm up as we go into the work week. Highs will slowly make it to the mid 60's before eventually hitting the 70's by Tuesday. Warmest day is expected to be Wednesday.
STILL TRACKING SHOWERS: Starting as early as Sunday night into Monday morning we'll see a chance of showers. Through the early half of the week, our chances will be low, but still a chance of an isolated shower or thunderstorm is possible. Our rain chance goes up later in the week and we'll have temps leveling off around 70. Although we have many days with rain chances total rainfall expected is less than an inch over the next 7 days.
FREEZE POTENTIAL: Saturday and Sunday morning we could see areas reach or go below 32 degrees. These temperatures could kill sensitive vegetation so be sure to protect them this evening.
SATURDAY: High pressure will move back into the Valley and give us mostly sunny skies. Temperature will stay cold with highs only around 50.
SUNDAY: Temperatures rebound back into the 60s with sunny skies.
WET PATTERN NEXT WEEK: We will see a couple of systems that could bring in some rain and storms. Monday a weak front will pass through during the morning and cause some showers. Another weak system could bring in more showers Wednesday and Thursday. A cold front Friday could bring in rain and storms. The storm threat looks non-severe right now.
A FREEZE WARNING HAS BEEN ISSUED FOR THE TENNESSEE VALLEY FROM 1 A.M. TO 10 A.M. SATURDAY MORNING AS TEMPERATURES WILL BE FALLING BELOW THE FREEZING MARK.
IN ADDITION, A HARD FREEZE WARNING IS ISSUED FOR WAYNE, GILES, AND LAWRENCE COS. TN WHERE TEMPERATURES WILL BE AT OR BELOW 28 DEGREES SATURDAY MORNING.
COLD END TO WEEK: A strong Northwesterly flow of winds will continue to keep the chill in the air. Huntsville experienced a 33 degree drop from 77 at 1 P.M. Thursday afternoon down to 44 degrees this morning. Clouds will clear out and we'll see some sunshine today, however, temperatures will barely make it into the mid 50's. By this evening, there is a chance of graupel, also known as soft hail, from a weak wave of energy. What is graupel? Very cold conditions move in from the North, causing upper level temperatures to reach near -30 to -40 degrees Celsius or -22 to -40 degrees Fahrenheit. When this happens, supercooled liquid in a cloud (liquid that stays as a liquid below the freezing mark) collides and sticks onto falling snowflakes within the cloud. When they combine, they create soft hail or graupel. It's a rare event for the Tennessee Valley as we usually never get this cold! Graupel is non-damaging, and is white in color as oppose to hail. In addition, hail occurs in warm weather events and graupel occurs in cold weather events.
TONIGHT: By tonight, we'll clear from this system to cause the Valley to drop into the upper 20's to lower 30's.
SATURDAY: On Saturday, we'll barely make it to 50 degrees with a mix of sun and clouds.
SUNDAY: Southerly winds return and we rebound back into the lower 60's for temperatures.
