Slight RIsk For Today
05/28/2009 07:41
Slight risk of severe weather today:
Greatest risk looks to be wind and/or hail:
Tornado risk is pretty low:
All this stormy weather should clear out by the weekend. Lows will be a very comfortable upper 50's with highs in the mid to upper 80's (YUCK - Summer is coming, and I HATE IT).

Boring Here, But Not So Much In The Middle
05/13/2009 10:32
The weather has been mostly boring around here of late... I'm sure there are a lot of folks who aren't complaining about that...
However, things look to be rough in the middle of the country today:
A new massive effort to study severe weather called VORTEX2 began just a few days ago... Today looks to be their first real chance at getting data! Good luck V2!!!

CONCERNING...SEVERE THUNDERSTORM WATCH 233...
VALID 032013Z - 032115Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 233
CONTINUES.
SQUALL LINE HAS DEFINITELY SLOWED TO AROUND 40KT AS IT PROGRESSES
ACROSS CNTRL INTO ERN AL...THOUGH PRIMARY BOW ALONG NRN SECTIONS OF
LINE IS RACING NNEWD AT ROUGHLY 50KT INTO TALLADEGA COUNTY. AHEAD
OF THIS BOW ECHO...ONE LONE SUPERCELL CONTINUES ITS NEWD TRACK ALONG
OLD BOUNDARY INTO CALHOUN COUNTY. THIS LEAD SUPERCELL SHOULD TRACK
INTO POLK/FLOYD COUNTY REGION OF GA WITHIN THE HOUR. GIVEN THE
FORWARD PROGRESS OF THIS LINEAR MCS HAS SLOWED IT APPEARS OVERALL
SEVERE THREAT WILL LINGER ACROSS WW233 FOR SEVERAL MORE HOURS. FOR
THIS REASON IT WILL BE NECESSARY TO EXTEND THE WATCH IN TIME.

Today's Severe Threat
04/02/2009 08:42
Looks to be a busy day in the land of weather, especially to our south and west... However, we could have a few strong to severe storms here in the Atlanta area as well. Please keep your ear out for watches and warnings today.
Here are the latest outlooks from SPC:

Severe Tomorrow?
04/01/2009 20:29
SPC has outlined a sizable "moderate risk" area to our west and south:
Keep your eye on the weather situation tomorrow! More info in the morning...
Oh... and one more thing... cold next week? a freeze? the "S" word? hmmm....

Rain Today - Severe Tomorrow
03/27/2009 10:05
Very rainy morning here in Atlanta... Expect the rain to continue for a couple more hours before tapering off this afternoon. However, more rain is on the way late tonight into tomorrow.
Here is the latest QPF (Quantitative Precipitation Forecast) from HPC:
Still some uncertainty about the severe potential for tomorrow. As of now, it looks like the area will be under the gun.
SPC has us under a "slight" risk for severe tomorow:
However... SPC has the probabilistic outlook at 45%:
That's fairly high, but uncertainty is keeping SPC from updating the risk beyond "slight".

Update On Rain And Severe Wx...
03/26/2009 23:01
So... Where is all that rain that the QPF maps were showing? Well... part of it just hasn't gotten here yet... and convection along the gulf cut off some of the moisture.
Here is the latest QPF map from HPC:
You can see that the amounts up our way have decreased a little. However, 10+ inches down in the Panhandle!? Wow...
Still watching the potential for severe weather in the area for Saturday. More on that tomorrow...

Severe Weather?
03/26/2009 10:01
Looks like it was a rough night over to our west, and there is a tornado watch this morning to the south. But for the Atlanta area, don't expect any severe weather until tomorrow/Saturday...
Here are SPC's outlooks for the next couple of days:
We also still have a LOT of rain coming over the next couple of days. Here is the QPF outlook from HPC:
The rain is certainly good news for the drought situation. Stay safe!

Heavy Rain And Maybe Severe
03/23/2009 21:40
If you have anything you need to do outside, better get it done tomorrow afternoon. Rain looks to be the story for the remainder of the week.
HPC's QPF outlook for the next 5 days shows us getting 4+ inches of rain. Excellent news as we are still very much in a drought.
With this much needed rain also comes the possibility of severe weather. SPC has our area highlighted for this coming weekend.
Meanwhile, crazy weather on the plains... Severe weather giving way to a blizzard... Spring has definitely arrived! Fun times ahead!

1 Year Ago...
03/14/2009 12:19
I was sitting on my couch catching up on episodes of LOST (which I've unfortunately gotten sucked into)... saw a flash of lightening in the distance and immediately had a strange feeling. I didn't recall that we were supposed to have severe weather until the next day... but that feeling in my gut stayed with me.
I started following the storm on radar as the lightening became really intense. I saw the velocity couplet and knew things were about to get interesting. Being the sensible person I am, I went outside!
The air was disconcertingly still. Just lots of lightening and thunder... no rain... no wind... nothing. Suddenly very large hail started to fall. The air continued to feel unnaturally still. Not good.
Then came the roar above. It sounded like it was really windy high above the trees, but nothing at ground level yet. It got louder and the tops of the trees started to really move. Intense and very scary... I knew what was happening. I just felt it in my gut. Curiosity and awe kept me frozen in place.
I live in a 1940's bungalow with no basement (no foundation built on piles). My center hallway closet was probably the best place to be, but I didn't go there. I just stood with my kitchen door open, watching everything going on outside. I just couldn't move.
The tornado touched down just two miles south of my location.

I keep a running history of notable weather events for Atlanta and update/add information often.
You can find the entry (including more pictures and videos) for the 2008 Atlanta Tornado here:

Drought And Spring Outlook (Updated)
03/05/2009 19:53
Very minor dent made in the drought with the heavy rain/SNOW last week. The outlook (bottom below) calls for some relief for the west side of the state (of Georgia). But I don't think we see much improvement in the drought situation any time soon. At least things are not as bad here as they are in Texas. Wow.
March, April and May look to be drier than normal as we are still stuck in this La Nina pattern from hell. Even worse, the rain we do get may come with more severe weather than "normal" the second half/end of March well into April. Think last year, but shifted out a couple of weeks (remember the Atlanta Tornado?).
I also think we will see some more cold weather too (maybe even another shot at frozen fun?!). A late season freeze in April (the kind that does serious damage to budding trees) would not surprise me either. Don't be fooled into thinking spring is finally here this weekend as temps push 80! Winter isn't quite ready to die... yet...
Enjoy the near "perfect" weather the next couple of days!

Backing Off Severe Threat
02/27/2009 10:00
The threat for severe weather doesn't look as great today as it was looking yesterday. SPC no longer has the Atlanta area at a "threat level" today. Still has a "slight risk" for tomorrow (though I think that will be dropped at some point).
The main threat today into tonight will be heavy rain and maybe a few strong thunderstorms. However, keep an eye on the weather today in case things change.

Heavy Rain & Severe Storms
02/26/2009 23:17
Heavy rain and the potential for severe storms will be the story over the next 36 hours. Severe storms are already showing up in AK, TN, and MS.
HPC shows nearly 5 inches of liquid precip for the Atlanta area over the next 5 days. Most of that falling tomorrow into Saturday.
Of course the other big story is the potential Southeastern SNOW storm. Models still show a storm, but as expected, each run shows a different area getting slammed. I'd say anyone from the Mississippi River to the East Coast has a shot. We'll (hopefully) narrow things down a little better tomorrow. Keep hope alive!!!

Severe Weather Potential
02/26/2009 08:43
Lots of interesting weather potential over the next few days into the weekend.
First up, the severe weather threat. SPC has put out a "slight risk" that includes the Atlanta for both Friday AND Saturday:
It's that time of the year, so naturally the ingredients are there for severe weather. We will have fairly good winds aloft with high shear/helicity values. The only limiting factor may be instability. This definitely needs to be watched.
As for the other interesting weather possibility... Stay tuned for the next post...

...MID-SOUTH TO SRN APPALACHIANS...
PRIOR/OVERNIGHT CONVECTION DISCUSSED IN DAY-2 OUTLOOK SHOULD
CONTINUE INTO EARLY THIS PERIOD ALONG/AHEAD OF SFC COLD FRONT. LOW
LEVEL WAA AND MOISTURE TRANSPORT WILL CONTRIBUTE TO SUFFICIENTLY
STEEP LAPSE RATES AND LOW LEVEL THETAE TO SUPPORT POSSIBLE
EARLY-PERIOD MCS MOVING EWD OR ESEWD ACROSS REGION. FCST DEEP-LAYER
WIND PROFILES WILL SUPPORT 40-50 KT EFFECTIVE SHEAR FOR ELEVATED
PARCELS AND POTENTIAL FOR ORGANIZED SVR THREAT...WITH HAIL AND
PERHAPS WIND DEPENDING ON DEPTH OF NEAR-SFC STABLE AIR.
DURING DAY...INTENSIFICATION OF MORNING ACTIVITY AND/OR ADDITIONAL
DEVELOPMENT ALONG ITS OUTFLOW BOUNDARY IS POSSIBLE...WITH SFC-BASED
SVR POSSIBLE. RESIDUAL/ELEVATED MIXED LAYER WILL CONTRIBUTE TO
CONSIDERABLE SBCINH DURING THIS PERIOD AS WELL...WITH FCST SOUNDINGS
SUGGESTING SHARP SRN CUT-OFF TO CONVECTION. SFC HEATING IS EXPECTED
TO WEAKEN CAPPING ALONG SRN RIM OF CLOUD/PRECIP AREA. STRENGTH AND
LOCATION OF MAX LOW LEVEL CONVERGENCE WILL DEPEND ON AFOREMENTIONED
CYCLOGENESIS AS WELL AS MESOSCALE PROCESSES ALONG FRONT AND/OR
BOUNDARIES FROM OUTFLOW AND DIFFERENTIAL HEATING. HOWEVER...MOST
PROGS REASONABLY INDICATE SUFFICIENT CONCENTRATION OF CONVECTION
OVER THIS REGION...AMIDST FAVORABLE DEEP LAYER SHEAR...TO SUPPORT

The Final Throws

*** TORNADO WATCH EXPIRED EARLY FOR NORTH ATLANTA AREA ***
It looks like we are at the tail end of this severe weather event. The tornado watch has been lifted for the city of Atlanta and north (but continues south of the airport for now). Still a good storm with lots of lightning and a little hail here in midtown now. It’s kinda nice actually.
Well.. That’s pretty much it for me tonight. LOST is coming on. Glad the severe weather is moving out. I’d be all sorts of bent out of shape if I lost my satellite signal.

Severe Storms Today. Weekend Buzz?
02/18/2009 08:02
It was fairly chilly when I walked outside to check my rain gauge. Quick glance at the thermometer showed 47. Doesn’t feel like severe weather outside at the moment.
But don’t let the cool morning fool you! Warmer temps and higher dew-points are on the way. A lot of shear and helicity are already in place upstairs. The stage is set for the possibility of severe weather later today.
SPC has put us in a slight risk (with moderate next door and to our south):
I don’t think today will be a big event for the Atlanta area. By that I mean it won’t be an “outbreak”. Can’t rule out an isolated tornado, but the main threat will be severe thunderstorms with the usual damaging winds, hail, and lightning.
Keep your eye on the weather today!
Meanwhile... Folks are buzzing about this weekend. After having my hopes dashed earlier this month (and all winter), I’m not getting excited about anything yet. If the buzz is still around tomorrow, then I might discuss it further.

So It Begins...
02/11/2009 08:16
The severe weather season is here. A number of folks lost their lives in Oklahoma yesterday.
Please take severe weather SERIOUSLY.
Fortunately, it looks like the current outbreak was limited to yesterday and will not repeat itself today in the Atlanta area. We will see some storms later today, most likely in the form of a squall line. My current guess is that it will be here around rush hour this evening. The biggest threat from this squall line will be brief heavy rain and high winds.
Keep an eye on the radar later today. You should be able to pick out the squall line as it comes in from the west. Click the radar below to see the latest “live” version.

Severe Weather Tomorrow?
02/10/2009 11:56
The SPC (Storm Prediction Center) has issued a “slight” risk of severe weather for a broad area across the Southeast and Ohio Valley.
As of now, it looks like the main threat for us in the Atlanta area will be wind. The threat for tornados should be fairly low.
However, please pay attention to the weather situation tomorrow in case severe weather develops for our area.
P.S. - How about your weather radio? Have one? Have backup batteries? Have it programmed for your area?
