A dangerous severe weather threat is developing for Kansas today, where a small but potent storm system in the western part of the state will intensify and move east. By late this afternoon, the storm will spawn supercell thunderstorms capable of bringing large hail and strong tornadoes to eastern Kansas and extreme western Missouri. NOAA's Storm Prediction Center has placed this region in its "Moderate Risk" area for severe weather, the second highest level of alert. Cities in the Moderate Risk area include Topeka, Kansas, and Kansas City, Missouri.

One-year anniversary of the April 27, 2011 Super Tornado Outbreak
One year ago today, an astonishing outbreak of atmospheric violence unparalleled in world history hit the Southeast U.S. A total of 199 tornadoes touched down, including eleven violent EF-4s and four maximum-strength EF-5s. The 4-day period April 25 - 28 was the largest and most damaging severe weather outbreak in world history, with a total of 358 tornadoes, $10.4 billion in damage, and 321 deaths.


Video 1. Remarkable video of the tornado that hit Tuscaloosa, Alabama on April 27, 2011. Fast forward to 4:15 to see the worst of the storm.


Video 2. CBS42 meteorologist Mark Prater tracks the Tuscaloosa, Alabama tornado of April 27, 2011.


Video 3. Five-minute look at the Tuscaloosa tornado of April 27, 2011 and the damage it wrought.

My husband and I were visiting my parents in Birmingham, Alabama. We decided to take a day trip to Tuscaloosa to see the damage from the April 27 tornado. It was a sight that I will never forget. Blocks and blocks of flattened houses and stores. This area has not been touched in 2 months. It was so moving that I started to cry thinking of all these poor people.

Footage from Hurricane Ivan. Ivan made land fall on September 16, 2004 as a Category 3 storm. It was the 10th most intense Atlantic hurricane ever recorded and the 6th costliest to the United States.

Good morning to all. It looks like Puerto Rico will be once again in 2012 under a rainy pattern next week.Here is an excerpt from the NWS of San Juan.

UPPER TROUGH ACROSS THE YUCATAN CHANNEL IS FORECAST TO
LIFT SLOWLY TO THE NORTHEAST OVER THE NEXT 72 HRS WITH UPPER RIDGE
WEAKENING ON MONDAY. THIS WILL ALLOW FOR DEEP LAYER INSTABILITY
TO INCREASE AND THEREFORE BETTER CHANCES FOR SHOWERS AND
THUNDERSTORMS THROUGH THE END OF THE WEEK.

Miami NWS Discussion

THE GFS AND NAM ARE BOTH SHOWING 20-30 KNOT SURFACE WINDS
OVER THE ATLANTIC WATERS AS THEY BOTH TRY AND DEVELOP A
HYBRID/SUBTROPICAL TYPE SYSTEM OFF THE SOUTHEAST COAST OF FLORIDA ON
SUNDAY...WITH A CLOSED SURFACE LOW OVER THE FLORIDA STRAITS. THE
ECMWF DOES NOT SHOW THIS...BUT DOES HAVE STRONGER WINDS ACROSS THE
ATLANTIC WATERS. SO IT APPEARS HEAVY RAIN WILL BE POSSIBLE LATE
TONIGHT ALONG THE EAST COAST DUE TO STRONG COASTAL CONVERGENCE. DID
NOT INCREASE WINDS DRAMATICALLY ACROSS THE REGION AND LOCAL
WATERS...AND INSTEAD OPTED TO DO A BLEND BUT STILL SHOWED SCA
CONDITIONS OVER THE ATLANTIC WATERS. BREEZY TO WINDY CONDITIONS MAY
BE POSSIBLE SUNDAY AFTERNOON...ESPECIALLY TOWARDS THE EAST COAST.

SURFACE HIGH PRESSURE IS EXPECTED TO GET REINFORCED SUNDAY INTO
MONDAY ACROSS THE ATLANTIC DUE TO HIGH PRESSURE MOVING OFF THE MID
ATLANTIC STATES. THIS SHOULD PUSH THE INVERTED TROUGH/HYBRID SYSTEM
BACK TO THE WEST IF IT DEVELOPS...AND BEGIN TO PULL THE DEEPER
MOISTURE AND HEAVIER RAINFALL BACK ACROSS SOUTH FLORIDA SUNDAY INTO
MONDAY. SO KEPT CHANCE TO LIKELY POPS ACROSS MOST OF THE REGION
THROUGH THIS TIME.

So, Keeper you seem a little doomdasish, we share that in common. Our outlooks on why differ, but I think we both feel something big could happen this year, be it a devastating hurricane, or a five minute 9.2 off the Oregon Coast. New Madrid going would send us to level red too. Anyone ever read what happens when the red card comes out?

REALLY excited about the 2012 HWRF upgrade coming in mid-May...

Highly suggest reading the full doc here

- Implement triple-nesting capability with a new centroid
based nest movement algorithm
- Configure the inner-most grid at cloud-resolving 3 km
horizontal resolution with explicit representation of
convective processes

- Implementation of GFS Shallow Convection
- Modifications to SAS deep convection, GFS PBL, GFDL
surface physics and Ferrier microphysics
parameterizations suitable for higher resolution and
based on observational findings
- Redesign of vortex initialization for 3 km resolution
with improved interpolation algorithms and better
representation of composite storm

- Improved POM initialization in the Atlantic domain and
new 1-D ocean coupling for Eastern Pacific basin
- Upgrade the HWRF GSI to V3.5 and use of new Hybrid
GSI/GFS for initial and boundary conditions once the
Hybrid GSI/GFS has been implemented operationally

- Improvements to HWRF Unified Post Processor to generate new
SSM/I simulated microwave satellite imagery products
***- Very high-resolution (every 5 sec.) storm tracker output
to support National Hurricane Center (NHC) operations


Test results from the combination of these upgrades showed significantly improved track, intensity and structure forecast skills and improved track, intensity and storm radius forecast biases in both Atlantic and Eastern North Pacific basins.

Product Changes:

The following elements will be added to the HWRF model output GRIB files:

-simulated microwave satellite imagery products from SSM/I-S
sensors

Yeah I've got that feeling that while in total activity this hurricane season won't be very busy, we will have some major surprises headed our way--just wait. I call for some land mass to be hit hard, so don't underestimate this hurricane season just yet--just because they call for a relatively calm one in total storms.
