Weather Blog: Labor Day Radar Update

From Jude Redfield...

Radar update (9:30am)

A couple downpours will occur for sections of Kentuckiana. Once the two clusters out west slide by we should actually watch rain/storm chances drop a bit this afternoon. We should also find skies brighten up a bit this afternoon. A few claps of thunder are likely, but the risk for severe weather remains VERY LOW.

Check out the satellite image below. We are stuck in the clouds for the next few hours, but indications still strongly suggest sun breaks will gradually develop from west to east this afternoon. While this might not be a 10 out of 10 kind of day, it could be a lot worse. A few brief downpours with any storm, but most of us will see a ton of dry time today. Have a great and safe Labor Day. -Jude Redfield-

A Brighter and Warmer Labor Day. Storms Loom Later in Week.

Appropriately, this August came to an end on a wet note.

For the 14th time this month, Louisville picked up measurable rainfall at the airport giving us a whopping total of 6.40" inches for the month.  Good for 8th wettest August on record. 

Almanac

Fortunately for us, the system responsible for all the clouds and wet conditions so far this holiday weekend is finally departing off to our east and it will give way to the return of sunshine for your Labor Day.

Gfx2

After some morning clouds and a slight chance of a shower, expect the sky to clear by afternoon with very warm highs into the upper 80's.  Enjoy!

Further west, we are tracking a cold front that is currently producing severe weather across portions of the Plains.  

Satrad

This front looks to arrive here with our next chance of storms late Monday night and into Tuesday.  

Jude will have a full update on what to expect first thing on WDRB in the Morning.

Radar Update: Tracking Showers & Storms...

It's a soggy morning for PARTS of our area as a round of rain moves to the northeast across Kentucky. Aside from a stray shower or sprinkle, Southern Indiana is dry at the moment. A Flash Flood Watch remains in effect until 2 pm for all counties shaded in green...

Gfs 1

The steady rain south of the river will taper off and become more scattered this afternoon. Everyone is fair game for a hit or miss storm later today. A good chunk of dry time is expected along and north of the Ohio if you have any outdoor plans. 

Earthquake

Clouds will block out the sunshine holding temperatures in the low 80's. Even though you may catch a break or two of sunshine this evening, skies will clear out just in time for tomorrow. Labor Day looks brighter with plenty of sunshine, warmer temps, and only an isolated storm chance.

More Heavy Rain on the Way. Flash Flood Watch Posted!

The 6.34 inches of rain we've seen at the Louisville International Airport is good for the 8th most ever during the month of August and it looks like we'll be adding to it as we head into the final day of the month.  

In fact, parts of our area could see some very heavy rainfall later tonight and into your Sunday where a Flash Flood Watch has been issued across our Eastern/Southeastern Counties.

Watch

At last check, radar was showing only light precipitation for areas along and north of the I-64 corridor.  

However, we are tracking a large area of moderate to heavy rainfall across muhc of Hart, LaRue, Green, Taylor, Marion and Washington Counties in Kentucky.

Rad

The rain continues a good distance to the southwest through much of Tennessee and into portions of the Lower Mississippi River Valley. 

Rad2

This large slug of moisture is moving towards the northeast and will bring more heavy rains for portions of our area over the next 24 hours.  

So how much are we talking about?  

NOAA's Weather Prediction Center has a bullseye of more than two inches of rain pegged across our southeastern counties where the Flash Flood Watch is in effect.  Lighter totals are expected into Southern Indiana with up to an inch additional possible.

After a locally strong storm went through portions of the metro area, we continue to track the development of a large area of rain with embedded thunder to our west.

While it appears the threat for severe storms will remain low, the potential will be there for some locally very heavy rainfall this evening and overnight.

Labor Day Weekend Forecast...

Labor Day weekend is here marking the unofficial end to summer. With all of the pool plans, football games, and BBQs we need to talk about rain chances. A majority of us are dry right now, but our northeastern counties have been and continue to get clipped by a line of storms. These will keep traveling northeast giving areas west of I-65 in Southern Indiana the best chance for rain this morning. It should dry out for a while this afternoon...

Ef4

Blog5

Sunshine will be limited as the clouds tend to lower and thicken with each passing hour. A few scattered storms are possible this afternoon for some. Everyone has a solid chance for rain overnight and into the first half of Sunday. Locally heavy rain may also lead to flash flooding which is something you want to keep in mind if you have travel plans...

Ef44

After a soggy start, storm chances should begin to taper off by Sunday afternoon. We might even catch a couple breaks of sunshine later on. With the clouds and showers during the morning, highs will be much cooler than they have been lately. After spending the last 10 days in the 90's, temperatures get knocked down into the 80's...

EURO

Much of Labor Day itself will be storm-free. However, as the atmosphere heats up and destabilizes, hit or miss storms will fire. Most of us will stay dry and in my opinion, Monday looks like the best day of the three. With plenty of sunshine highs will top out in the low 90's...

Today Is The Anniversary Of Katrina! Watch The Video I Shot While Chasing That Monster...

9 years ago today, I was standing on the coast in Gulf Port, Mississippi watching Hurricane Katrina demolish the city.  We saw a wall of water over 20 feel tall in my location that absolutely plowed through everything it hit. I was astronished at how tall the storm surge was and how long the brutal winds lasted in Katrina. When we left the parking garage we have used to protect us from the eye wall of this monster, we saw destruction that I will never forget. In tonight's blog, I want to show you the video of what I saw while chasing Katrina. The part of the video you want to watch starts at 7:33 and ends at 10:36.

 

 

 

 The NWS has a recap of Katrina with some of the facts from this legendary storm...

 

Remembering Hurricane Katrina

9 years ago

 

(IR image of Katrina on August 28th around peak intensity)

 

August 29th  marks the 9th anniversary of Hurricane Katrina landfall in southeast Louisiana and  coastal Mississippi.  Katrina was an extraordinarily large, powerful and deadly hurricane that  carved a wide swath of catastrophic damage and inflicted large loss of life across the area. After reaching Category 5 intensity on the Saffir Simpson Scale over the central Gulf of Mexico, Katrina weakened to Category 3 before making initial landfall near Buras, in lower Plaquemines Parish 0610 AM CDT on Aug 29, with a second landfall a few hours later near the mouth of the Pearl River, east of Slidell, LA.
  
Pressurelandfall pressure in lower Plaquemines Parish was 920 mb making this the 3rd lowest pressure recorded in United States by a landfalling tropical cyclone. Only the 1935 Labor Day Hurricane in the Florida Keys (892mb) and the 1969 - Hurricane Camille on the Mississippi Coast (909mb) produced lower pressure.

Winddata from aircraft reconnaissance indicates that maximum sustained winds at landfall were around 110 knots or 127 mph and due to power outages along with wind damage prior to the storm, many wind anemometer failed before the most intense part of the hurricane arrived at the coast. Some unofficial wind observations in the area included East New Orleans 107 kts/123 mph - Slidell Airport 87 kts/100 mph - Pascgoula MS 108 kts/124 mph - Poplarville MS 117 kts/135 mph.

Storm SurgeDue to the large breadth of hurricane force winds along the coast, Katrina produced a deep and devastating storm surge across the coastline from Southeast Louisiana and Lake Pontchartrain to Mobile Bay.The maximum high water mark indicated a storm surge 27.8 feet near Pass Christian, MS.   A storm surge in excess of 15 feet occurred across a wide area from St Bernard and Plaquemines Parish to Jackson County, MS.  Storm surge extended inland for over 6 miles along the Mississippi Coast and crossed Interstate 10 in several locations.

ImpactsThe most devastating impact from the Hurricane Katrina was the storm surge, resulting in inundation of large sections of the coast from southeast Louisiana and the New Orleans area across the Mississippi Coast. An estimated 1200 people lost their lives, with many more from indirect causes. Thousands of homes and businesses were destroyed and severely damaged. Total damages were estimated at $108 billion, making Katrina the costliest hurricane in U.S. history.

Video Of The Day: Mount Tavurvur Volcanic Eruption...

A volcanic eruption on Papua New Guinea has led to nearby communities being evacuated and some international flights being diverted. Mount Tavurvur began spewing lava early Friday in Rabaul district on East New Britain Island. The government said in a statement that residents of Rabaul town, the provincial capital, had been advised to remain indoors to avoid falling ash. Here is raw video of the eruption...

Weather Blog: Very Wet At Times

From Jude Redfield...

    The split the pot holiday weekend means some of the 3 days will be just fine, but the other parts will be wet and cloudy.  Rain rates of 2"-3" an hour are likely with any t-storm. We do have an outside chance for a severe storm or two, but like the last few weeks severe weather is not likely. What makes this holiday system different than the last few days centers around the thick clouds and lack of sunshine at times along with higher chances for widespread rain/storms late Saturday and parts of Sunday.  Some rain gauges will end up with 1" - 3" by Monday. Louisville could be in a top 5 wettest Augusts by the time the month is over.  **While Sunday looks pretty cloudy, I still feel some dry times will be noted on and off Sunday**

I chose these two time stamps for the future radar/satellite so you could see a general idea of the kind of coverage we will expect from time to time on Saturday and Sunday.

**The risk for damaging wind and hail remains very low, the risk for frequent lightning and soaking rain is very high**

I strongly urge you to check in with Rick and Jeremy this weekend if you have any outdoor plans. They will provide the most specific rain and storm forecasts of anyone in town starting tomorrow morning at 6am.
