Volcanic sunsets, Gustav, Labor Day forecast

Good morning bloggers,

Happy Labor Day!  We are having another colorful sunrise this morning without any clouds in the sky.  Why?  A volcano erupted in Alaska on August 7th:

From Spaceweather.com http://spaceweather.com/:

VOLCANIC SUNSETS: Sky watchers across the USA and Europe have been reporting unusually colorful sunsets and sunrises. The cause appears to be the August 7th eruption of the Kasatochi volcano in Alaska. The volcano hurled a massive cloud of ash and sulfur dioxide into the stratosphere; high winds have since carried the aerosols over parts of the USA and Europe, producing widespread "volcanic sunsets."

Here is a picture I took last week.  The orange color is being caused by the sun reflecting off of the ash in the stratosphere.  Last night I watched the cirrus clouds illuminate first, and then the ash turned orange after the cirrus color faded, which indicated that the ash was in the stratophere above where most of our weather occurs in the troposphere:

Gustav is hugging the Louisiana coastline this morning.  At 6:45 this morning they eye is just offshore of Grand Isle, LA with 115 mph winds with gusts to near 130 mph.  New Orleans is not getting the brunt of the hurricane, and this seems very different than Katrina of three years ago.  We will know the impact of Gustav on New Orleans within hours.   

Tropical Storm Hanna is strengthening this morning and this is the next big concern to the east coast of the United States. 

And, a cold front is approaching our region.  As Gustav moves inland today, there will be an interaction with the cold front as the front gets absorbed into Gustav's circulation.  Look below at the 00z GFS valid Tuesday morning:

Some of the computer models have tried to stall Gustav over northeastern Texas.  But, I am not sold on this stalling solution yet.  The farther west Gustav ends up, the better chance that we will have more of an impact.  Missouri is likely going to get a deluge of rain, but Kansas City is still seemingly on the edge of this system.  The combined effort of Gustav and the cold front may bring us a very fall like day on Wednesday with some rain and temperatures in the 50s.

We will be tracking these developments on NBC Action News Midday (11 AM), and then at 5, 6, and 10 PM tonight. 

Have a great Labor Day! 

Gary

Thank you Gary.  I read on the blog yesterday that because hurricanes move counterclockwise, that whoever is east of the eye gets the brunt of the storm.  Up above, it seems like you are contradicting that?  I'm sure I misunderstood - I always thought that wherever the eye directly hit got the worst of it (before and after the eye anyway) - is that true?  Laura

------------------

Laura,

Yes, the worst part of the hurricane will be near the eye wall.  So, if you are in the eye, then this means you had the full impact from the hurricane.  But east of the eye is where the worst storm surge will be, and this causes a lot of the devestation.

thats not always the case hummerseeker.

the deepest convection is on the w and sw sides of gustav.  generally speaking though,  the east side has the healthier storm surge.

cat 2 storm at landfall with a more westerly jog impending...who called it?

I hope we get a lot of rain but not 50's!!!!

50s are okay if it's sunny - but not rainy!  Has it ever been in the 50s in September before?  Guess our contest is over, huh?  I'm sure I'm in the bottom 5% with 24 days over 90!  LOL

------------------

Yes, the contest is over.  We will talk about it later today.

And, having a high in the 50s during September has happened many times.  I doubt Wednesday high will be in the 50s but lower to middle 60s are likely.

Quiet on the blog today..... but if anyone is interested, I found this link that combines several of the networks in La... you can pick from 5 live video streams.

I'm looking forward to the fall like days this week!  And some beneficial rain.  Hope Gustav quickly fades down to just a good old rain storm as it moves north.

pvt, you were right.  In the future, I will disregard the NHC and all other scientists.  I will go with you!

Gary... "Some of the computer models have tried to stall Gustav over northeastern Texas.  But, I am not sold on this stalling solution yet. "

Care to elaborate?

------------

Scott,

As the tropical system moves northwest it will slow down and begin to be affected by the upper level flow strengthening to our northwest.  It will pick up the remnants of Gustav and kick it out northeast.  The big question is where will the westward extent be?  So, it will almost stall, move north and then get kicked out.

We may get some substantial rainfall before the affects of Gustav move through on Wednesday.  Later Tuesday and Tuesday night will be an interesting interaction between the front and Gustav.

What I find most amusing is not a category 2 Hurricane Gustav, but the Bush Administration's reaction to the hurricane coming close to where Katrina did three years ago, when they couldn't be bothered at all to pay attention.  Boy, what an election year does!  Gustav will come ashore with the same type of damage and flooding that any other category two hurricane does and, at any other time, you'd be hard pressed to see the media or any politcian pay an ounce of attention.

Oh...so that explains the colorful sunsets I have been seeing this past month.   Very pretty:)

Hopefully Gustav will roll on through with minimal damage and everyone can return home safely and easily.  

I am impressed though, they finally figured out how to move almost the entire population & pets of a major city (and surrounding area's too) for an emergency evacuation.  I hope every state examines that model and takes notes.

Despite 911, and if I'm remembering right (anyone with better knowledge please correct me) it seems that up til now, and despite the threats of hurricanes, volcanoes, earthquakes, and floods, no one really had a seriously viable plan that was feasible to work.  The response to Katrina showcased that all too well.  But they did it, and well done.

Ok, off my soapbox now :o)

One question about the volcano... I know that sometimes when the ash gets high in the air, it can cause an over all cooling of the climate...(I think it was Mt. Pinatubo before?)  Will this Alaskan explosion have any impact other than the gorgious sunsets?

Have a great day everyone!

Zazel,  Personally, I don't find anything amusing about a devastating hurricane.  Did you know how bad Katrina was going to be or that the levees wouldn't hold?  What does matter is that Mayor Nagin, the governorship, and our compassionate President Bush did learn from the experience.  Even the residents learned because they were willing to evacuate this time.  Politics had nothing to do with the improvements that were made in preparation and handling of this hurricane.  It is not very kind to trounce on others.

Tropical Storm Hanna has now just been upgraded to a 75 mph Hurricane. There is also another TD off the coast of Africa...I wonder in it will be named in the next couple days.

It is definitly getting very active out there. I think it is going to be a very active September.

pvt_murphy said:

to elaborate on alex's thoughts, i think the first half of september will be active, but things will slow down a bit as the cape verde season winds down in the second half...and then we will be back to following the late season stalled out gulf fronts before you know it...

Johnson County Old Settlers is being held this week in Olathe, I'm getting a little concerned about the rain possiblities and the remenants from Gustav.  I'm the Coordinator for the Art/Crafts, any idea how much rain and or wind we could expect.  Thursday,Friday and Saturday are my main concerns.

Thanks,

Gary, do you know where I could find more about the new 09 ride at Worlds of Fun, Prowler? Jeff V talked a bit about it before the Today show came on.

I am not sure!  Go to Jeff Vaughns blog and ask him there.

I'm curious as well about the subject of ash from volcano's creating a globaly lower temperature.  My son was telling my husband and I a little about it the other day.  Doe's it take a massive erruption to have that effect?  Also since I am asking questions what if any impact could Hanna have on us?  Just guessing my family in Michigan might at least get some rain out of it.

Gary B,

Gary B won!  Congratulations.  I will go and double check, but I am pretty sure you are the winner.

I'm glad to know why the skies have been amazing.  A group of us were enjoying a block party yesterday and we were just amazed with the colors.  Hard to believe an eruption from 3 weeks ago is still affecting the atmosphere.

Zazel I find your comments on hurricane response uncalled for.  Do you realize that disaster response and evacuation plans are the responsibility of the city and state government?  President Bush never told the Mayor and Governor to throw away their evacuation and disaster plans before the new ones were in place.  The governor did this on her own.  It was not the federal government's fault that the City of New Orleans diverted monies sent to them to repair the pumps and levies for their own projects.  They thought this would never happen.  This is exactly what happens when local governments continue deferring maintenance projects.  It comes back to haunt you!  A comment was on the television this morning asking the current governor's staff why this hurrican response is so much different than that of Katrina?  The staffer's response what that this governor holds his people accountable for their jobs and their performance.  Seems to me there is competencancy in local government now.
Sorry to bring this up but everyone wants to pass the buck and not put responsibility where it belongs.  The federal government's job is to assist in disasters like hurricanes and tornadoes, not take over.

I saw a couple of questions about volcanos.  A couple years ago there was a volcano somewhere.  We noticed that our cars had this reddish dust/ash all over them.  I mentioned it to several other people at work (which is 25 miles from here) and they all said they noticed it somewhat.  Someone said it was volcano ash.  Could that be true?  I don't know where the volcano was, or even when, but when you mentioned the ash making beautiful skies, I wondered if that same ash could fall down farther.  That would work for a great excuse not to waste my energy washing the car!  :)

Where did the shower come from?  I was all set to pull out the mower and give the front and side yard a once over, and this little gray cloud went right over my house & dumped all over.  What a downpour!  Now everything is soaked - including my car seats :(  
September 1, 2008 6:47 PM
 

EMPulse said:

Ditto what StormWyndd said.  All of the sudden, we had a little pop-up shower come right on top of us here in Claycomo.  I checked your radar images, and it literally materialized out of nowhere.  Although, I see that it's moving north out of the SSE.  Could this be a little spin-off from Gustav?

----------

The evening showers can be indirectly related to Gustav.  We just went under the broad circulation from this system late this afternoon.

Gary, we just got back from taking our boys out.  Our oldest one rode without training wheels for the first time.  When we got home, I just hit the button to turn on our sprinklers.  As soon as I hit it, the drops began to come down.  My wife said. "Either you're really good or it's starting to rain."  It's pouring up here at NE 76th and N Tullis. Finally.  We missed out on those overnight downpours last week.

It's raining at my house right now! You can see the sun, so it's pretty small.  Heavy rain too.

Gary,

Just a friendly FYI:  You may want to consider properly attributing others' writings to them when you copy and paste the work of someone else.  It appears as though you're seeking to pass off that work as your own by leaving out the author's name and signing your name at the bottom of the post.  

I've seen in on this blog several times when you take the work of another (in this case, that of a Spaceweather.com writer) and paste it here without attribution.  I would assume you wouldn't want someone doing the same with your work.  I just wanted to throw that out there before an original author comes after you more harshly than one of your readers!

Thanks Notes, I should have added in the link!  Stay on top of it!  I appreciate it more than you know.

Wow...even the mere possibility of temps in the 50s on Wednesday has me thinking about Fall. Soon sweatshirt weather will be here before we know it.

kcwxguy said:

I got the rain too...seems many in the metro got it.  Go figure, didn't recall even a chance for today.

I suspect if RSS was set up correctly, weather stories would be much easier to produce..albeit given proper notation to the original writer...

LOL

I look forward to the cooler temps for now, but suspect we will have more than our share of cooler weather through the fall/winter.  That is just my opinion based on my own thoughts...not to be confused with anything LRC like.

Maybe I will create a Fall Map.

Gary,
   The Navy NOGAPS model has Gustav heading directly over us and the NAM seems to have it headed this way.  What does it look like to you?

Mary,

The trend is there, but let's see how it looks today.
