JULY 2015: The month is over and we are coming in at number 4 for hottest July on record for Huntsville International Airport. The North West Alabama Regional Airport didn't even come close to the top 10.
WEATHER SUMMARY: High pressure and dry air will linger through the weekend. We will see daily highs in the low 90s and see plenty of sky conditions just like this.
THE DRY AIR HAS ARRIVED: Most of the summer has seen hot and humid conditions, but that wont be the case this weekend. Starting Friday we'll see temps in the lower 90's with dew points in the lower 60's. This will greatly take the edge off of the temperatures and make it feel more comfortable outside. The dry air will hang around through the weekend, although, temperatures will climb into the mid 90's.
LITTLE TO NO RAIN: In addition to having dry air in place, we won't have to worry too much about rain chances. For kids that go back to school next week, this means that you'll have a near perfect final weekend of summer. Anything you want to do outdoors, this is the weekend to do. Best chance of rain comes next Thursday with 20 percent chance of an isolated shower.
HOTTER WEATHER NEXT WEEK: Temps are expected to climb back into the upper 90's next around mid week. For the most part, we wont have as oppressive heat indices as we've seen the rest of this July. Temps will drop again late next week as our rain chance increases.
A viewer sent me a message on Facebook asking what was this large circle on radar that has been in the same exact location the last two days. Just coming and going in a little over an hour.
The answer for this was birds. If you were awake between the hours of 5:30 a.m. and 6:45 a.m. you probably saw a large flock of birds flying about the sky. This was located in southeastern Limestone County and originated from some farmland. Which is a perfect place for birds to eat and sleep.
Even looking at the velocity data you can see the speed and direction of how fast they are flying in the different directions.
You can see a lot of different things on radar: bugs, birds, bats, insects, butterfly migrations, traffic, chaff and smoke plumes just to name a few.
COOLER, DRIER WEEKEND: After a cold front works through the valley, we will be set up perfectly for the weekend. Our highs will top off in the lower 90's, but with lower dew points it'll will feel so much more comfortable outside. We'll have plenty of sunshine making this weekend perfect for just about anything outdoors. Rain chance will remain minimal through the weekend. Although temps will still feel much cooler this weekend, they will remain above average.
HEAT RETURNS NEXT WEEK: Those muggy temps aren't done with us just yet, we'll have highs returning to the upper 90's next. A few models are hinting at possible triple digit heat by Tuesday, although that seems unlikely right now. We'll have heat indices in the 105-110 range through at least Wednesday next week, and likely into next Thursday as well.
HEATED HISTORY: On this date back in 1930 we recorded the highest temperature at the Huntsville International Airport.
THURSDAY: A cold front will move through the Valley. Most of the area will be dry with the small chance of some isolated showers or Sand Mountain. Highs will still make it into the low 90s.
FRIDAY AND BEYOND: High pressure comes back to the southeast. Initially this system will bring drier and slightly cooler weather. Overnight lows will be comfy going into the mid to upper 60s. The weekend will have complete sunshine with highs in the mid to upper 90s. Even with the heat in place it won't feel all that bad with the dew points staying in the mid to upper 60s. Temperatures will continue to be in the mid to upper 90s but we will see dry conditions for the first full week of August.
A HEAT ADVISORY IS STILL IN EFFECT FOR PARTS OF THE TENNESSEE VALLEY UNTIL 7 P.M. WEDNESDAY
A cold front is ready to shake, rattle, and roll into the Tennessee Valley come this afternoon and evening. Gusty winds will be the primary concern in excess of 30 to 40 mph possibly making a few of these thunderstorms on the stronger side. Overall a 1/2 of an inch of rain could accumulate today.
We look to stay quiet tonight as a northwesterly flow of wind behind this cold front will slowly start to break the humidity and drop our temperatures into the mid 90's. The key phrase is "break in humidity" as we will not have to worry about the heat index heading into Friday and Saturday. In fact, overnight lows will dip into the mid to upper 60's come Friday and Saturday night, perfect weather to get an early morning hike in or walk the dogs!
Temperatures and humidity creep back up come Monday as higher pressure will move in to turn our winds back in from the South to pump in warm, muggy air into the Tennessee Valley for the beginning of the workweek.
HEAT ADVISORY: The heat advisory is valid for most of the viewing area. Even if you are not in the advisory you should still adhere to the heat safety rules during this time. The heat advisory will be lasting until 7 p.m. Wednesday. Heat index values could still make it between 105-110 at times.
WEATHER SUMMARY: We will continue to be hot and muggy through Thursday. After the cold front arrives Thursday we will see drier and slightly cooler temperatures as we go into the weekend.
WEATHER SUMMARY: We will continue to be in an unstable air mass that will allow for isolated to scattered showers and storms through Thursday. Now this may change with the speed of the cold front. We won't be seeing upper 90s by the end of the week but before that front arrives that's a different story. We will most likely see a heat advisory issued for at least parts of the Valley Tuesday if not for everyone. That will be that National Weather Service's call. But with expected heat index values around 105 Tuesday and Wednesday I would think that we will have one issued.
After the front we will see "cooler" weather. By cooler I mean lower 90s for Friday but it will feel a lot better with dew points in the low to mid 60s compared to the low to mid 70s like we have seen this past weekend.
The heat is on for the beginning of the workweek as higher pressure moving towards the Carolinas as southerly winds will continue to send in hot and steamy air into the Tennessee Valley. Temperatures will stay into the upper 90's until Wednesday, where the heat index will make it feel like it's into the triple digits.
By Wednesday afternoon, a cold front will be sliding in from the North Central Plains to give us scattered showers and a dip in temperatures for the end of the workweek. A northwesterly flow of winds will move in come Thursday to drop temperatures a bit along with making it feel more comfortable outside as the humidity levels will lower.
TEMPERATURES REMAIN HOT: Through the early half of the work week, temps will remain in the mid and upper 90's with heat index values over 100 degrees. Overnight lows will be muggy and mild in the mid 70's. Most afternoons will be very uncomfortable with high dew points making it feel very sticky. We'll have lots of sunshine, with some beautiful afternoons through the early week which also means limited chances for rain. Monday through Wednesday will have only isolated showers at best, although some models are trying to bring in a weak disturbance Tuesday which would give us better rain chances.
RAIN LATE WEEK: Best chances for rain arrive later in the week, as early as Thursday according to some models. I beleive most will arrive by Friday giving us at least a few showers and storms. The cold front itself will knock our temperatures back down to the lower 90's, maybe even the upper 80's. The weekend isn't looking like a washout, but it will have the best chance of rain for the next 7 days.
