Anonymous Coward User ID: 34563829 Portugal 02/16/2013 06:30 PM Report Abusive Post Report Copyright Violation | Forecast discussion for Minneapolis hints at the possibility of over a foot of snow, getting very exciting! THE MAIN CONCERN FOR THE LONG TERM IS WHAT DEVELOPS FROM THE DEEP TROUGH DIGGING INTO THE SOUTHWEST TUESDAY NIGHT/WEDNESDAY. MODELS ARE IN RATHER GOOD AGREEMENT FOR THIS RANGE IN SHOWING A SURFACE LOW DEVELOPING OVER SERN CO/SWRN KS/PANHANDLES OF OK/TX WEDNESDAY EVENING. THIS LOW WILL TAP INTO CONSIDERABLE TROPICAL MOISTURE FROM SEVERAL DAYS OF EASTERLY FLOW FROM THE CARIBBEAN. IN ADDITION...THE INFLUENCE OF HIGH PRESSURE WILL BE SLOW TO EXIT WITH AN EASTERLY WIND PREVENTING COLD AIR FROM RETREATING. AS THE LOW EJECTS NORTHEASTWARD...IT WILL WEAKEN SLOWLY WITH TIME BUT WELL ESTABLISHED WARM AND COLD CONVEYOR BELTS WILL ALLOW FOR AN EXPANSIVE SNOW SHIELD TO DEVELOP ACROSS THE NORTHERN/CENTRAL PLAINS BY WEDNESDAY EVENING. THIS SNOW SHIELD WILL ADVANCE EASTWARD ACROSS SRN MN AND WRN WI THURSDAY AFTERNOON AND WILL ENGULF THE ENTIRE CWA THURSDAY NIGHT. 30 TO 50 KT WIND ON THE 280K SURFACE WILL MEAN VERY STRONG ISENTROPIC LIFT THURSDAY EVENING AND LEAVES LITTLE DOUBT THE SNOW SHIELD WILL REMAIN WELL INTACT. AS THE LOW CONTINUES TO WEAKEN AND OCCLUDE THURSDAY NIGHT/FRIDAY... THE WARM CONVEYOR BELT TOO WILL WEAKEN AND A WINDING DOWN OF SNOW INTENSITY WILL TAKE PLACE. REX BLOCKING WILL KEEP THE LOW SOMEWHAT CLOSE TO THE GREAT LAKES WITH CYCLONIC FLOW LIKELY REMAINING IN PLACE THROUGH THE WEEKEND WITH A CONTINUATION OF PERIODS OF LIGHT SNOW. AS MENTIONED BEFORE...THE MODELS ARE IN RATHER GOOD AGREEMENT WITH THIS SCENARIO...INCLUDING WITH TIMING AND INTENSITY. THEREFORE... RAISED POPS INTO THE DEFINITE CATEGORY WHICH IS QUITE RARE AT THIS RANGE BUT HIGH CONFIDENCE SUPPORTS IT NONETHELESS. MAKING SNOWFALL PREDICTIONS AT THIS RANGE IS RARE AS WELL...BUT QPF ON ALL DETERMINISTIC MODELS EXCEPT FOR THE ODDBALL 12Z CANADIAN ARE AT LEAST 0.6 INCHES AND SOME APPROACH OR EXCEED 1 INCH. WITH A 15:1 RATIO AS A ROUGH GUESS...IT IS CONCEIVABLE MUCH OR ALL OF THE CWA COULD SEE 8 TO 12+ INCHES...ESPECIALLY ACROSS THE SOUTH WHERE THE MODELS HAVE BEEN MOST CONSISTENT IN PLACEMENT OF THE HEAVIER PRECIPITATION. |

THE LATEST MEDIUM RANGE FORECAST GUIDANCE MAINTAINS GENERAL TRENDS OF THE PAST SEVERAL DAYS CONCERNING A MAJOR UPPER TROUGH AND ASSOCIATED STRONG JET STREAK THAT APPEAR LIKELY TO EMERGE FROM THE SOUTHWESTERN U.S. BY THE MIDDLE OF THE COMING WORK WEEK. THE TROUGH AXIS STILL APPEARS LIKELY TO TAKE ON A NEGATIVE TILT AS IT PROGRESSES ACROSS THE SOUTHERN ROCKIES INTO THE CENTRAL AND SOUTHERN PLAINS BY 12Z THURSDAY...BEFORE LIFTING NORTHEASTWARD AND DEAMPLIFYING ACROSS THE UPPER MIDWEST ON FRIDAY. PRIMARY SURFACE CYCLOGENESIS IS EXPECTED ACROSS EASTERN COLORADO INTO WESTERN KANSAS...BUT MODELS INDICATE SECONDARY WAVE DEVELOPMENT FROM PARTS OF NORTHWEST INTO EASTERN TEXAS WEDNESDAY NIGHT. THIS MAY EVENTUALLY BECOME THE FOCUS FOR AN EVOLVING SQUALL LINE...AND INCREASING SEVERE WEATHER POTENTIAL...AS FORCING ENCOUNTERS BETTER MOISTURE RETURN OFF THE GULF OF MEXICO. HIGHEST SEVERE PROBABILITIES STILL APPEAR TO EXIST ON THURSDAY...AS THE WAVE AND ASSOCIATED SQUALL LINE DEVELOP EASTWARD ALONG A WARM FRONT ACROSS THE LOWER MISSISSIPPI VALLEY. SURFACE DEW POINTS IN THE WARM SECTOR OF THE WAVE MAY REACH THE MID 60S ACROSS PARTS OF SOUTHEAST TEXAS INTO SOUTHERN LOUISIANA AND MISSISSIPPI. ASSOCIATED BOUNDARY LAYER DESTABILIZATION ON THE SOUTHERN PERIPHERY OF THE DIFLUENT HIGH LEVEL FLOW AND MID-LEVEL HEIGHT FALLS COULD BECOME SUPPORTIVE OF DISCRETE SUPERCELLS NEAR/AHEAD OF THE SQUALL LINE... WITH A RISK FOR TORNADOES...IN ADDITION TO DAMAGING WIND GUSTS. |
