Fierce storm hammers Southeast U.S.
The Southeast U.S. is under the gun today from a combination of severe thunderstorms, high winds, heavy rain, and coastal storm surge flooding. A tornado was reported on the ground near Eglin Air Force Base, Florida this morning, and tornado warnings have been posted for two separate squall lines moving through the Florida Panhandle and neighboring regions of Alabama and Georgia. These squall lines are expected to intensify and generate tornadoes, heavy rain, and strong winds as they push eastwards today. The Storm Prediction Center (SPC) has put most of Florida, Georgia, South Carolina, and North Carolina in their "Slight Risk" category for severe weather today, warning of the possibility of supercell thunderstorms capable of spawning tornadoes. If the air mass in front of these squall lines becomes sufficiently unstable this afternoon due to solar heating of the lower atmosphere and other factors, SPC may need to upgrade their severe weather category to "Moderate Risk", the second highest level of risk.

The storm's powerful winds blowing over the Gulf of Mexico have created storm surges of 2 - 3 feet along the coast, from New Orleans to the Florida Panhandle. A storm surge of two feet was recorded in Waveland, Mississippi last night and this morning, which caused flooding of low-lying roads in Hancock County. New Orleans recorded 2.42" of rain yesterday from the storm, breaking their record for the rainiest December 1. Radar-estimated rainfall (Figure 2) shows up to five inches of rain has fallen over some regions of the Florida Panhandle, and additional rainfall amounts of 2 - 5 inches are expected along the track of the storm as it heads north-northeast today. Flash flooding was reported in Charleston, SC this morning, closing several roads.

Also receiving a pounding from the storm were the Gulf Coast beaches from Dauphin Island, Alabama, to the Florida Panhandle near Pensacola. A storm surge of two feet, topped by battering waves 10 - 12 feet high, probably caused millions of dollars of erosion damage last night and this morning. A 16-mile stretch of man-made beach encompassing the Alabama coastal communities of Gulf Shores and Orange Beach suffered $5 million in erosion damage from the pounding delivered by Tropical Storm Ida last month. The two beach communities, along with Gulf State Park, spent about $24.2 million in 2005 to strengthen 16 miles of shoreline by dredging about 6 million cubic yards of sand from the sea floor and dumping it on shore. Hurricanes Gustav and Ike in 2008 did about $9.5 million in erosion damage to the Gulf Shores beach. Because the beach is man-made, the Federal Emergency Management Agency and the Alabama Emergency Management Agency treated it as they do bridges and highways, paying 85 percent of the tab to repair storm damage.

The embattled director of the Climate Research Unit (CRU) of the UK's University of East Anglia announced that he will be temporarily standing aside as director until an independent review resulting from allegations following the publication of emails illegally hacked from his computers. I'll be posting a response tonight or Thursday morning, assuming that today's storm does not generate a deadly tornado outbreak. I'm also working on a post titled, "Don't Shoot the Messenger", in response to charges by the Wall Street Journal in an editorial yesterday that climate scientists have a vested interest in promoting alarmist views of the climate in order to get research funding.

the front is way back in GA, hasnt even passed through ATL
This, from Slidell (NOLA WFO) seems to be a very thorough and competent assessment of the dynamics involved, to me.
A VERY UNUSUAL SNOW EVENT LOOKS TO DEVELOP OVER PORTIONS OF THE FORECAST AREA WITHIN THE NEXT 72 HOURS. FOR THIS EVENT TO DEVELOP...SEVERAL FACTORS MUST COME TOGETHER AT THE RIGHT TIME. CURRENTLY...FORECAST GUIDANCE HAS A FAIRLY GOOD HANDLE ON THE MID-UPPER LEVEL DYNAMICS OF THIS SYSTEM...AND ARE IN VERY GOOD AGREEMENT ON THE TIMING AND STRENGTH OF THE UPPER LEVEL TROUGH. IN FACT...IT APPEARS THAT SOME VERY VIGOROUS UPPER LEVEL LIFT WILL BE TAKING PLACE ACROSS THE REGION LATE FRIDAY INTO EARLY SATURDAY. THIS WILL PLAY A ROLE IN THE SNOWFALL EXPECTED OVER THE NORTHERN THIRD OF THE CWA. THE DIFFERENCES ARISE IN THE LOW LEVEL DEVELOPMENT OF THE LOW PRESSURE SYSTEM...AND THE TIMING OF THE DRY AIR INTRUSION AT AROUND 850MB LATE FRIDAY NIGHT INTO EARLY SATURDAY MORNING. ALL OF THE MODELS DEPICT A STRONG GULF LOW DEVELOPING OVER THE WESTERN GULF OF MEXICO ON FRIDAY...AS A POSITIVELY TILTED UPPER LEVEL TROUGH AXIS DIVES SOUTHWARD THROUGH THE SOUTHERN PLAINS. THIS LOW WILL FORM IN A REGION OF ENHANCED BAROCLINICITY CENTERED AROUND A STALLED FRONTAL BOUNDARY. THE LOW WILL CONTINUE TO DEEPEN IN RESPONSE TO A JET COUPLET THAT IS EXPECTED TO DEVELOP OVER THE WESTERN GULF FRIDAY AFTERNOON. BY FRIDAY EVENING...THE LOW WILL BE OVER THE CENTRAL GULF OF MEXICO. STRONG MOISTURE ADVECTION IN THE MID-LEVELS WILL TAKE PLACE FRIDAY EVENING ACROSS THE REGION AS THE LOW MOVES THROUGH THE GULF. THIS MID-LEVEL MOISTURE...COMBINED WITH SOME UPPER LEVEL MOISTURE MOVING IN WITH THE UPPER LEVEL TROUGH AXIS WILL BE THE FUEL THAT FEEDS THE PRECIPITATION EVENT FRIDAY NIGHT. AS STATED BEFORE...THE MODELS ARE IN GOOD AGREEMENT ON THIS SITUATION.
AT THE SAME TIME THAT THE MOISTURE BEGINS TO FEED INTO THE REGION...COLDER AIR WILL BE DRAWN SOUTHWARD IN RESPONSE TO THE STRENGTHENING SURFACE LOW IN THE GULF. TEMPERATURES WILL BEGIN TO FALL ACROSS THE CWA FRIDAY AFTERNOON AS THIS COLDER AIR MOVES IN. THE MOST NOTICABLE TEMPERATURE CHANGES WILL BE FROM 800MB DOWN TO THE SURFACE. MODEL SOUNDINGS SHOW A GOOD 5 DEGREE DROP IN TEMPERATURES FROM 18Z FRIDAY TO 06Z SATURDAY. THIS DROP PLACES THE LOWER ATMOSPHERE INTO A MORE FAVORABLE ZONE FOR SNOW DEVELOPMENT FOR AREAS ACROSS SOUTHWEST MISSISSIPPI AND PARTS OF SOUTHEAST LOUISIANA NORTH OF I-12. AS A RESULT...EXPECT SNOW TO DEVELOP SOMETIME IN THE LATE EVENING HOURS FRIDAY AND LINGER THROUGH THE NIGHT. ACCUMULATIONS ARE HARD TO PINPOINT AT THIS TIME...BUT SOME ACCUMULATION WILL BE POSSIBLE.
THE MAIN DIFFERENCES ARISE IN THE EXACT DURATION OF THE SNOWFALL. THE GFS AND ECMWF BOTH DEPICT STRONG DRY AIR ADVECTION TAKING HOLD BY 12Z...WITH THE STRONGEST DRYING IN THE MID-LEVELS. HOWEVER...THE NAM CONTINUES TO HOLD MID-LEVEL MOISTURE IN THE REGION FOR A FEW MORE HOURS...BEFORE SHOWING STRONG DRYING AROUND 18Z. AT THIS TIME...HAVE LEANED MORE TOWARD THE GFS AND ECMWF...WITH DRYING TAKING PLACE EARLY SATURDAY MORNING.
0 Z should be along any time now, unless wx conditions warranted canceling the launch.

from Wiki:
Surge was a citrus soft drink first introduced in Norway, under the name Urge (1996), by the Coca-Cola Company to compete with Pepsi's Mountain Dew.
History
In 1996, Coca-Cola decided to start producing Urge in the United States under the name Surge, although in Denmark, Norway and Sweden, the name remained the same.
blah blah yadda yadda
Coca-Cola now makes Vault, a soda which contains many similar ingredients to Surge, and therefore has a very similar taste.
Urge: the Norwegian predecessor to Surge
Urge logo closeup. Text in the bottom-right corner says "Sitrussmak(Citrus taste)"
Norway is the only country where one can still buy this soft drink. Surge was widely associated with the extreme sports lifestyle, with television commercials similar to those currently used by Mountain Dew. Expired cans and bottles of Surge now sell on eBay for high dollar amounts, including a reported $160.08 for a 12-pack sold in April 2005.[1]
We only have like THIRTEEN weather radios here so this place is like NORAD.
WAAAA WAAA WAAAA ERRRRRRPPP EEEERRRP and now they have extended our tornado watch (#752) until 4am. Previously it was only till 10pm.
can someone give me the new map please?
(eeerp)
That same graphic is on JAX weather timed 5:39 AM, Wednesday.
And things do change. Tell you what, I'll do my weather and you do yours. Deal?
haha i see norad and i automatically think COD MW2 :D
...
well, we DO have to test our inventory...
Forecasting snow across much of the Southern US is a challenge, there must be adequate cold air in the upper levels down to ground level. You have to have moisture and lift.
The scenarios that play out in the Northern US differ greatly from the Southern US, as the GOM averages 60-75F, even during the winter.
Too much warm air advected warms the atmosphere and causes many of our Southern winter weather events to be freezing drizzle/rain or sleet. Most N TX winter weather events are caused by warm gulf air advecting over the colder surface air, and fall under that catagory of ice/freezing rain/drizzle.
We shall soon find out how the scenario plays out come FR into SA.
not really im 17 and thats one of my favorite movies... tic tac toe is a great game :D
The Uruguay and Parana rivers in N/E Argentina have overflowed their banks after days of torrential rain. Thousands have been evacuated...
A huge area is affected.
Only high enough for the direction change in wind direction to take hold...in that sounding I posted, 300 mb level would be enough, theoretically.
Broiled, self-caught, fresh-as-can-be Black Drum waiting for me...L8R.
Slurp!
Cloud tops in most tornadic thunderstorms usually are at least 35,000 FT. However some tornadic cells go all the way up to 75,000 FT.
In order to produce a tornado, you need lift and shear. The lift, or forcing can be caused by warm air being forced up and over cold air. The changing of wind with height, or wind shear, causes the warm air parcel to rise very quickly and turn with height, These elements in combination cause super-cell and tornadic activity.
Landspout
Not sure what happened to the first link. LoL
L8R
Hey! good idea, thanks!! (:
Didnt even think of that! And the history of it is rather interesting indeed
Bless you! MOST people just kinda' say, "It ain't gonna happen to me"! Well, this atmosphere is loaded with energy. The tilted trough is forcing tons of warm, tropical air up into the Carolinas. The wind shear and the LLJ are adding insult to injury.
This most likely will NOT be a widespread tornadic outbreak. HOWEVER, the shear levels are causing the cells to spin, so discreet super-cells can create a EF1 or greater tornado, with little to no warning. The LLJ winds can be carried down to the surface by the squall line.
You are a "smart" weather watcher. You are prepared to "expect the unexpected"! My concern is for those folks that say, "It ain't gonna happen to me". "When you least expect it, expect it to happen to YOU"..

SPOTTER MEASURED GUST OF 60 MPH WITH AN ANEMOMETER. (TBW)
Too early to tell if it will even happen.
For snow, 3 things have to come together at the same time:
1. Cold temps in a deep layer of the atmosphere.
2. Enough moisture in the air to generate precip.
3. Something to set it all off.
Right now, the temps are looking good. The moisture is looking good, too. The question is the timing of the shortwave coming from the Rockies... will it get to Houston in time to meet the moisture before the high pushes it away?
IF (and that is a HUGE "if") it snows, max accumulations will likely be one inch. Inside Houston proper, you likely won't get much accumulation due to the heat island effect.
Sadly we lost Lorenz a year or so ago...
