Re: Tornado Alley Forecasts, Nowcasting and Reports
aggiornamenti molto ma molto interessanti per oggi.
Primo High Risk della stagione!!!
SPC AC 010613
DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1213 AM CST THU MAR 01 2007
VALID 011200Z - 021200Z
...THERE IS A HIGH RISK OF SVR TSTMS TODAY ACROSS PARTS OF ERN
MISSISSIPPI AND ALABAMA...WHERE POTENTIAL EXISTS FOR AN OUTBREAK OF
TORNADOES...SOME POSSIBLY STRONG OR VIOLENT....
...THERE IS A MDT RISK OF SVR TSTMS SURROUNDING THE HIGH RISK
AREA...ACROSS MUCH OF THE LOWER HALF OF THE MISSISSIPPI VALLEY AND
GULF/SOUTH ATLANTIC COAST STATES....
...THERE IS A SLGT RISK OF SVR TSTMS TODAY/TONIGHT ACROSS A LARGE
PORTION OF THE CENTRAL/EASTERN STATES....
LARGE SCALE PATTERN ACROSS THE U.S. DURING THIS FORECAST PERIOD WILL
BECOME DOMINATED BY A DEEP CYCLONE NOW DEVELOPING ACROSS THE CENTRAL
PLAINS...IN RESPONSE TO AN INTENSE MID/UPPER JET STREAK NOSING
NORTHEAST OF THE SOUTHERN ROCKIES. UPPER JET CORE IS PROGGED TO
SHIFT THROUGH THE SOUTHERN PLAINS/NORTHERN GULF STATES AND SOUTHERN
APPALACHIANS TODAY THROUGH EARLY FRIDAY...WITH SURFACE CYCLONE
GRADUALLY OCCLUDING AS IT LIFTS THROUGH THE UPPER MISSISSIPPI
VALLEY/UPPER GREAT LAKES REGION. AS THIS OCCURS...A COLD FRONT WILL
SURGE EAST OF THE MISSISSIPPI VALLEY...LIKELY REACHING ATLANTIC
COASTAL AREAS BY 12Z FRIDAY. AND...MODELS SUGGEST SECONDARY SURFACE
CYCLOGENESIS MAY OCCUR FROM THE LEE OF THE NORTH CENTRAL
APPALACHIANS INTO NORTHERN MID ATLANTIC COASTAL AREAS.
ALTHOUGH GULF RETURN FLOW MAY NOT BECOME OF SUFFICIENT QUALITY TO
SUPPORT WIDESPREAD SIGNIFICANT DESTABILIZATION ACROSS THE CENTRAL
AND EASTERN STATES...IT SHOULD BE ADEQUATE ENOUGH TO SUPPORT AN
EXTENSIVE CONVECTIVE OUTBREAK...GIVEN FAVORABLE LARGE SCALE FORCING
FOR UPWARD VERTICAL MOTION. STRONG WIND FIELDS/SHEAR WILL SUPPORT
SEVERE POTENTIAL ACROSS A BROAD AREA...INCLUDING A RISK OF STRONG
TORNADOES AND STRONG STRAIGHT LINE DAMAGING WINDS... PARTICULARLY
ACROSS PARTS OF THE GULF INTO SOUTH ATLANTIC COAST STATES.
...PARTS OF THE CNTRL GULF STATES/TENNESSEE VALLEY...
WHILE STRONGER MID-LEVEL FORCING SHIFTS NORTHEAST OF THE LOWER
MISSOURI/MIDDLE MISSISSIPPI VALLEY DURING THE MIDDAY AND AFTERNOON
HOURS...LARGE-SCALE ASCENT IS EXPECTED TO WEAKEN CAP SUFFICIENTLY
FOR MORE SCATTERED CONVECTIVE DEVELOPMENT EAST OF THE LOWER
MISSISSIPPI VALLEY. THIS MAY COMMENCE AS EARLY AS THE 15-18Z TIME
FRAME ACROSS PARTS OF WESTERN TENNESSEE/MISSISSIPPI...BEFORE
SPREADING ACROSS ALABAMA DURING THE PEAK AFTERNOON HEATING HOURS.
WITH BOUNDARY LAYER DEW POINTS CLIMBING THROUGH THE MID 60S
CONTRIBUTING TO MIXED LAYER CAPE OF 500 TO 1000 J/KG...SUPERCELLS
ROOTED NEAR THE SURFACE WILL BY ACCOMPANIED BY A RELATIVELY HIGH
RISK OF TORNADOES. LARGE...CLOCKWISE CURVED HODOGRAPHS BENEATH A
STRONG UPPER JET WILL BE SUPPORTIVE OF A FEW LONG-LIVED/LONG TRACK
SUPERCELLS WITH STRONG OR VIOLENT TORNADOES.
...MIDDLE MISSISSIPPI/LOWER OHIO VALLEY/MID ATLANTIC COAST...
EVOLUTION OF SQUALL LINE IS EXPECTED EARLY IN THE PERIOD ALONG/
AHEAD OF SURFACE FRONT IN RESPONSE TO STRONG FORCING. FORCING WILL
COMPENSATE FOR ANTICIPATED WEAK INSTABILITY...AND DAMAGING WINDS
COULD BECOME WIDESPREAD AS ACTIVITY SURGES EASTWARD. STRONG
LOW-LEVEL SHEAR WILL SUPPORT A RISK FOR ISOLATED TORNADOES...
PARTICULARLY EARLY TODAY FROM PARTS OF EASTERN MISSOURI INTO
INDIANA. COOLER/DRIER BOUNDARY LAYER FARTHER EASTWARD INTO THE OHIO
VALLEY SEEMS LESS FAVORABLE FOR TORNADOES...BUT A DAMAGING WIND
THREAT IS EXPECTED TO CONTINUE THROUGH THE APPALACHIANS... AND
POSSIBLY NORTHERN MID ATLANTIC COASTAL AREAS BY 12Z FRIDAY.
...SOUTHERN MID ATLANTIC COASTAL AREAS...
BOUNDARY LAYER IS EXPECTED TO RECOVER NORTHWARD THROUGH THE
CAROLINAS BETTER THAN FARTHER NORTHWARD ALONG THE ATLANTIC SEABOARD.
AND...THIS SEEMS TO SUPPORT A MORE CERTAIN SEVERE THREAT LATE THIS
EVENING/OVERNIGHT. WITH A 60 TO 80 KT SOUTHERLY LOW-LEVEL JET
PROGGED TO EVOLVE TO THE LEE OF THE APPALACHIANS... DAMAGING WINDS
APPEAR LIKELY TO BE PRIMARY SEVERE THREAT WITH PRE-FRONTAL
CONVECTIVE LINE/LINES. THOUGH LOW-LEVEL WIND PROFILES ARE EXPECTED
TO BE LARGELY UNIDIRECTIONAL...LOW-LEVEL SHEAR WILL STILL BE EXTREME
AND FAVORABLE FOR AT LEAST AN ISOLATED TORNADO THREAT.
...CENTRAL FLORIDA PENINSULA...
LOW-LEVEL FLOW/SHEAR IS ONLY EXPECTED TO BE WEAK TO MODERATE IN
STRENGTH...BUT DEEP LAYER SHEAR SHOULD BE MORE THAN SUFFICIENT FOR
ISOLATED SUPERCELLS. WEAK CAPPING SHOULD ALLOW FAIRLY WIDESPREAD
CONVECTIVE DEVELOPMENT AS MOIST BOUNDARY LAYER WARMS WITH
INSOLATION.

molto ma molto significativo il PSWO
Public Severe Weather OutlookPrint Version ZCZC SPCPWOSPC ALL WOUS40 KWNS 010834 ALZ000-MSZ000-011630- PUBLIC SEVERE WEATHER OUTLOOK NWS STORM PREDICTION CENTER NORMAN OK 0234 AM CST THU MAR 01 2007 ...A MAJOR SEVERE WEATHER OUTBREAK IS LIKELY ACROSS THE LOWER OHIO VALLEY...LOWER AND MID MISSISSIPPI VALLEY...EASTWARD ACROSS THE GULF AND SOUTH ATLANTIC COASTAL STATES. THE NWS STORM PREDICTION CENTER IN NORMAN OK IS ALSO FORECASTING THE DEVELOPMENT OF A TORNADOES...SOME WHICH MAY BE STRONG AND LONG TRACKED...ESPECIALLY ACROSS EASTERN MISSISSIPPI AND ALABAMA. THIS AREA IS IN A HIGH RISK FOR SEVERE WEATHER. THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE ALABAMA EASTERN MISSISSIPPI SURROUNDING THE HIGH RISK AREA...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS ACROSS MUCH OF THE LOWER HALF OF THE MISSISSIPPI VALLEY AND GULF/SOUTH ATLANTIC COASTAL STATES. A POWERFUL UPPER LEVEL SYSTEM WILL TRANSLATE EASTWARD FROM THE MID MISSISSIPPI VALLEY INTO THE EASTERN PORTIONS OF THE COUNTRY THE NEXT 24 HOURS. A COLD FRONT WILL ACCOMPANY THIS SYSTEM...ALONG WITH VERY STRONG JET LEVEL WINDS. AT THE SAME TIME...STRENGTHENING SOUTHERLY WINDS ARE RAPIDLY TRANSPORTING MOISTURE NORTHWARD AHEAD OF THE FRONT. SEVERE STORMS ARE ALREADY ONGOING THIS MORNING ACROSS PORTIONS OF THE MISSISSIPPI AND TENNESSEE VALLEYS...AND WITH DAYTIME HEATING...THE COVERAGE OF SEVERE STORMS ARE EXPECTED TO INCREASE. THE MOST INTENSE STORMS ARE EXPECTED FROM LATE MORNING AND INTO THE AFTERNOON HOURS ACROSS EASTERN MISSISSIPPI AND ALABAMA. THESE STORMS WILL BE IN A VERY FAVORABLE ENVIRONMENT STORMS TO ROTATE AND SPAWN LONG TRACKED...STRONG TORNADOES. STRONG TORNADOES ARE ALSO POSSIBLE LATER TODAY ACROSS PORTIONS OF TENNESSEE AND GEORGIA....WHILE WIDESPREAD WIND DAMAGE AND ISOLATED TORNADOES ARE LIKELY ACROSS MUCH OF THE LOWER OHIO VALLEY. THIS IS POTENTIALLY A VERY DANGEROUS SITUATION. THOSE IN THE THREATENED AREA ARE URGED TO REVIEW SEVERE WEATHER SAFETY RULES AND TO LISTEN TO RADIO...TELEVISION...AND NOAA WEATHER RADIO FOR POSSIBLE WATCHES...WARNINGS...AND STATEMENTS LATER TODAY. ..IMY.. 03/01/2007

Re: Tornado Alley Forecasts, Nowcasting and Reports
alla fine il target di ieri con l'aggiustamento verso il confine del KS poteva valere quelche tornado, anche se le celle correvano veloci.
vediamo ora di scegliere un target nel marasma di oggi...

io come al solito vi faccio le veci delle updates via internet sul campo...
ho gia inserito tutti i radar in interesse nella zona viola, i NEXRAD ed i satelliti nel mio armamentario..da quando sorgerà il sole sarò presente agli aggiornamenti.
comunque belle prospettive.

Re: Tornado Alley Forecasts, Nowcasting and Reports
chiedo un favore a StormChaser (e a tutti): visto che ne siete già in possesso, mi potreste fare un breve elenco dei link di satelliti e radar della zona?
Nexrad già incamerato nei preferiti...mi mancano i satelliti a scala nazionale
Vi ringrazio in anticipo
