TWO DEATHS CONFIRMED!!!! Compared with cleveland superbomb Good Morning Folks. All eyes turning to pending weather in the Mid-West today and further East tomorrow courtesy of the front and warm flow from the Gulf. Here is a portion of the am SPC discussion on the set-up in the Mid-West today. DAY 1 CONVECTIVE OUTLOOK NWS STORM PREDICTION CENTER NORMAN OK 0650 AM CST TUE JAN 29 2013 A MOIST AIR MASS ALREADY IN PLACE ACROSS THE SRN PLAINS IS SUPPORTING AN INCREASINGLY UNSTABLE ENVIRONMENT WITH MLCAPE UP TO 1000 J/KG EXTENDING FROM NORTH TX INTO CENTRAL OK...ALONG AND EAST OF THE DRY LINE. STRONG HEIGHT FALLS SPREADING EWD WITH THE LONGWAVE TROUGH AND LEAD SHORTWAVE TROUGH MOVING ENEWD THROUGH THE SRN HIGH PLAINS HAS SUPPORTED THE ONSET OF STRONG TO SEVERE ORGANIZED STORMS PRIOR TO THE START OF DAY 1 OVER WRN OK. THIS INCREASE IN DEEP LAYER ASCENT IS ALSO EVIDENT FARTHER TO THE NORTHEAST JUST AHEAD OF THE POLAR FRONT IN NRN OK TO SERN KS AND SWRN MO WHERE STORMS HAVE BEEN INCREASING IN COVERAGE AND INTENSITY SINCE 10-11Z. THE TORNADO AND DAMAGING WIND PROBABILITIES AND SLIGHT RISK AREA HAVE BEEN EXTENDED WWD TO INCLUDE MORE OF NORTHWEST TX...WRN AND NRN OK INTO ERN KS. THIS CHANGE IS DUE TO THE ONGOING STRONG TO SEVERE STORMS AND THE LIKELIHOOD FOR ADDITIONAL ACTIVITY WITH SWD AND NEWD EXTENT ALONG THE DRY LINE AND POLAR FRONT...RESPECTIVELY. Starting to wonder if we might see a Derecho type line later today as daytime heating increases in the afternoon in the warm sector. [link to www.wunderground.com] |

TWO DEATHS CONFIRMED!!!! Compared with cleveland superbomb 371. ILwthrfan01:18 PM GMT em 29 de Janeiro de 2013 Temperatures already in the low 60's across much of Central Illinois. We are already at or within record highs for the day at 7am EST. Absolutely unreal. Decatur, IL low temperature last night of 58 F. Currently 61 F. I would not at all be surprised if SPC issued a high risk today if the sun can get out and add to the instability from the Arkansas to Southern Illinois. They have already expanded the tornado outlook from the previous advisory. This is rapidly becoming a dangerous situation. [link to www.wunderground.com] |

TWO DEATHS CONFIRMED!!!! Compared with cleveland superbomb AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 406 AM CST TUE JAN 29 2013 ...SEVERE WEATHER OUTBREAK EXPECTED ACROSS THE REGION TONIGHT INTO EARLY WEDNESDAY... .SHORT TERM...FORECAST MODELS CONTINUE TO SHOW SOLID AGREEMENT ON THE OVERALL SETUP FOR THE EVENT (OUTBREAK) AND CONTINUE TO CONVERGE ON TIMING AS KEY FEATURES EVOLVE ACROSS THE AREA. OPTED TO USE THE OUTBREAK WORDING AS THIS EVENT WILL COVER A GOOD PART OF THE NEARBY REGION (MULTIPLE CWA`S) WITH OUR CWA BEING A PART OF THE MAIN EVENT. ANOMALOUS WARMTH/MOISTURE HAVE PRIMED A LARGE PORTION OF THE CENTRAL CONUS AHEAD OF AN IMPRESSIVE AND POTENT UPPER TROUGH. LOOK FOR ADDED WARMTH ALONG WITH A MORE PRONOUNCED SURGE OF MOISTURE TODAY AS THE ATMOSPHERE REALLY RESPONDS IN ADVANCE OF OUR SYSTEM FOR TONIGHT. FOR TODAY...THE MAIN FOCUS WILL BE WINDS. THE PRESSURE GRADIENT WILL TIGHTEN AS LOW PRESSURE DEEPENS OVER THE SOUTHERN PLAINS. ADDITIONALLY...VERY WARM CONDITIONS WILL TAKE SHAPE AND ALLOW FOR GOOD MIXING. THIS COMBO WILL LEAD TO WINDY/BREEZY CONDITIONS THIS AFTERNOON AND EVE. FOR NOW...WILL LEAVE THE GOING WIND ADV AS IS. DEPENDING ON HOW THE GRADIENT SHARPENS AND EFFECTS OF MIXING...THE ADV MAY HAVE TO BE EXPANDED ACROSS THE NE CWA (N OF I-20 & E OF I-55). NOT EXPECTING PRECIP TODAY AS A STRENGTHEN CAPPING INVERSION WILL KEEP PRECIP FROM DEVELOPING. THE MAIN EVENT FOR OUR AREA WILL BE LATER THIS EVE INTO THE OVERNIGHT HOURS AS STRONG ASCENT AND LOW LEVEL MOISTURE CONVERGENCE WILL HELP REMOVE THE CAP. ALL GUID SHOWS SUCH DEVELOPING ALONG AND JUST AHEAD OF A PRE-FRONTAL TROUGH (PSEUDO-DRY LINE). THIS FEATURE HAS AND CONTINUES TO BE DEPICTED WELL BY ALL GUID AND IS A CLASSIC FEATURE THAT BRINGS SIGNIFICANT SVR WX TO OUR REGION. CAN`T SAY I`VE SEEN IT IN JANUARY THOUGH. ASSOCIATED WITH THIS FEATURE WILL BE INTENSE WIND SHEAR WITH PROGGED 0-1KM SHEAR OF 40-50KTS AND EFFECTIVE SRH OF 400-650 M2/S2. WE USUALLY STRUGGLE TO GET ANY INSTABILITY THIS TIME OF YEAR...MUCH LESS HAVING SOME COMBINED WITH HIGH SHEAR. WELL...MODEL DATA CONTINUES TO SUPPORT 600-900 J/KG OF MLCAPE AS LONG AS TEMPS HOLD BETWEEN 71-73 AND DEWPTS ARE 66-67. SUCH CAPE/SHEAR COMBO SUPPORTS 0-1KM EHI VALUES OF 2 TO 3 WHICH ARE QUITE HIGH. SUCH AN ENVIRONMENT WILL SUPPORT A HIGHER END EVENT WITH SIG SVR WX POSSIBLE. WITH SUCH A FAVORABLE ENVIRONMENT BECOMING ESTABLISH OVERNIGHT TO SUPPORT SVR STORMS...THE KEY ON WHAT THE AREA WILL SEE HAS TO DO WITH STORM MODE (LINEAR OR DISCRETE CELLS). MODEL DATA IS GOOD AGREEMENT ON THIS SHOWING A MIXED MODE...FOR AT LEAST A PART OF THE TIME BEFORE A LINEAR MODE BECOMES DOMINATE. SOME DISCRETE ACTIVITY LOOKS POSSIBLE BY 9 PM OVER THE NW PART OF THE CWA AHEAD OF THE EVOLVING LINE. THESE STORMS WILL STORMS WILL QUICKLY LIFT NNE AND POSE A TORNADO AND DMG WIND RISK. HERE SEEMS TO BE MAIN AREA TO SUPPORT A STRONG TORNADO. AS WE APPROACH MIDNIGHT...THE LINE WILL BECOME MORE DOMINATE AS IT EVOLVES EASTWARD. HI-RES DATA SHOWS A LINE SEGMENT STRUCTURE OR QLCS TYPE STRUCTURES FOR THE REST OF THE NIGHT. DUE TO THIS...TORNADOES WILL CONTINUE TO BE A THREAT AND WE CAN`T RULE OUT A STRONG ONE DURING THIS TIME AS WELL. HOWEVER...DMG WINDS WILL BECOME MORE OF A FOCUS. DUE TO THE VERY STRONG WINDS IN THE LOWER 5KFT...60-80 MPH TYPE WINDS MAY EASILY BE BROUGHT DOWN TO THE SFC WITH ANY STORM. DUE TO THIS...EXPECTING A WIDESPREAD DMG WIND EVENT ALONG WITH THE TORNADO RISK MENTIONED ABOVE. WITH ALL OF THIS...WILL UTILIZE THE GRAPHICS TO HIGHLIGHT AN ENHANCED RISK AREA...MAINLY ALONG AND NORTH OF A LINE FROM WINNSBORO TO MACON. AS FOR AS HEAVY RAIN...NOT TOO CONCERNED AS QUICK MOVEMENT AND EVOLUTION LOOKS TO KEEP MOST PRECIP TOTALS AROUND .5 TO 1.0 INCH. STILL...RAINS WILL BE EFFICIENT AND SOME AREAS COULD SEE A VERY QUICK 1 INCH. AS FOR TIMING...WILL HAVE TO KEEP A BROAD WINDOW ACROSS THE W/NW TO CAPTURE THE PERIOD OF PRE-LINE ACTIVITY AND THEN THE ACTUAL LINE ITSELF. LOOK FOR AREAS WEST OF A KOSCIUSKO TO NATCHEZ LINE TO OCCUR BETWEEN 9PM AND 3AM. FROM 2-7AM...AREAS EAST OF A NATCHEZ TO WINONA LINE WILL SEE THE SQUALL LINE QUICKLY MOVE THROUGH. |

Compared with cleveland superbomb THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH CENTRAL ILLINOIS... NORTHEAST ILLINOIS AND NORTHWEST INDIANA. .DAY ONE...TODAY AND TONIGHT. WEATHER HAZARDS EXPECTED: THUNDERSTORMS...POSSIBLY SEVERE CAPABLE OF PRODUCING: TORRENTIAL DOWNPOURS. DAMAGING WINDS IN EXCESS OF 60 MPH. AND ISOLATED TORNADOES. AREAS AFFECTED AND TIMING: SCATTERED THUNDERSTORMS ARE LIKELY TODAY...BECOMING MORE WIDESPREAD LATER THIS AFTERNOON OVER NORTH CENTRAL ILLINOIS AND SPREADING EAST INTO NORTHEASTERN ILLINOIS AND NORTHWEST INDIANA THIS EVENING. THE GREATEST THREAT OF SEVERE THUNDERSTORMS APPEARS TO BE THIS AFTERNOON INTO EARLY EVENING OVER NORTH CENTRAL ILLINOIS...SPREADING EAST INTO NORTHEAST ILLINOIS AND NORTHWEST INDIANA THIS EVENING. DISCUSSION: WIDELY SCATTERED THUNDERSTORMS WILL OCCUR TODAY IN THE UNSEASONABLY HUMID AND RECORD WARM AIR THAT HAS OVERSPREAD THE AREA. A STRONG COLD FRONT WILL MOVE SLOWLY EAST TOWARD THE REGION TONIGHT WITH THUNDERSTORMS LIKELY TO DEVELOP OVER IOWA AND MISSOURI THIS AFTERNOON...SPREADING EAST INTO THE REGION LATER THIS AFTERNOON INTO THIS EVENING. IT IS UNCLEAR WHETHER SUFFICIENT INSTABILITY WILL EXIST FOR SEVERE THUNDERSTORMS THIS AFTERNOON AND EVENING. HOWEVER...WITH SUCH EXTREMELY STRONG WINDS ABOVE THE GROUND IT WOULD ONLY TAKE A SLIGHT AMOUNT OF INSTABILITY TO SUPPORT A RISK OF DAMAGING WINDS AND POSSIBLY EVEN TORNADOES...SO THERE IS A CONDITIONAL RISK OF SEVERE THUNDERSTORMS SHOULD SUFFICIENT INSTABILITY DEVELOP. A NEARLY UNPRECEDENTED AMOUNT OF MOISTURE FOR THIS TIME OF YEAR HAS SPREAD INTO THE REGION WHICH WILL SUPPORT WIDESPREAD HEAVY RAINFALL AND THE ACCOMPANYING RISK OF FLOODING LATER THIS AFTERNOON INTO TONIGHT. .DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY. ACCUMULATING SNOW IS POSSIBLE WEDNESDAY...ESPECIALLY OVER NORTH CENTRAL ILLINOIS. .SPOTTER INFORMATION STATEMENT... SPOTTERS MAY BE NEEDED THIS AFTERNOON AND EVENING. && |
