Vortex2 tornado study finally gets some twisters to study

A proven way to reduce the incidence of dangerous weather phenomena is to schedule a multi-million dollar field experiment to study the phenomena. Up until this past weekend, that has certainly been true of this year's $10 million Vortex2 tornado study. The 7-week study (which also runs next year) has deployed an armada of over 100 storm chasing vehicles across the Great Plains this Spring, but has largely been frustrated by an exceptionally quiet tornado season. Tornado activity in May was less than half of what was observed last year in May, thanks to a ridge of high pressure that has dominated the weather. The residents of Tornado Alley ran out of luck over the weekend, though, as a strong low pressure system and associated cold front brought severe weather and multiple tornadoes to the region. Sixteen tornado reports were received by NOAA's Storm Prediction Center yesterday, and three on Friday. The team of University of Michigan students that has been writing our featured Vortex2 blog caught some excellent pictures of tornadoes on both Friday and Sunday. Yesterday was probably the last best chance for the Vortex2 project to document a strong tornado, since the project ends this Saturday and no significant tornado outbreaks appear likely for the remainder of this week.

Aurora, Colorado tornado yesterday
A tornado with a 3/4 mile wide debris cloud swept through Aurora, Colorado yesterday, staying on the ground for 8 - 11 miles and damaging a shopping mall, but causing no deaths or injuries. The tornado passed close to one of the high-resolution Terminal Doppler Weather Radars (TDWRs) that we now feature on our web site (see the radar FAQ for more details on these great new additions to our radar offerings). Posted below are the reflectivity and Doppler velocity images from the tornado, showing the amazing fine-scale details these high-resolution radars offer.



Figure 1. Radar reflectivity (top) and Doppler velocity (bottom) from the Denver, Colorado Terminal Doppler Weather Radar (TDWR), which caught the classic signature of a supercell thunderstorm tornado over Aurora, Colorado. A tornado dropped down from the low-level mesocyclone inside the parent supercell thunderstorm at the time of these images. Yellow colors located right next to greens/blues indicate that winds are moving towards and away from the radar in close proximity, the signature of strong rotation at low levels. Also visible on the plot are the winds spreading out from a downdraft on the rear side of the tornado. Black arrows denote the direction of wind flow. The dryline was bent back into a E-W orientation near Denver, creating an area of moisture convergence, which triggered thunderstorm formation.

Western Caribbean disturbance unlikely to develop this week
As area of disturbed weather over the Western Caribbean has brought rains of 2 - 3 inches over portions of Nicaragua and Honduras over the past few days. Wind shear is a high 20 - 30 knots over the disturbance, and no computer models are indicating that the disturbance will develop this week.

Today looks pretty righteous for the Vortex2 crew. It just ain't gonna get any better than today.



DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0100 AM CDT TUE JUN 09 2009

VALID 091200Z - 101200Z

...THERE IS A MDT RISK OF SVR TSTMS ACROSS PARTS OF KANSAS...
...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF THE CNTRL AND
SRN PLAINS...OZARKS AND MID-MS VALLEY...

...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF NEW YORK...ERN
PA...MD AND NJ...

...CNTRL AND SRN PLAINS...
SOUTHWEST FLOW WILL BE IN PLACE ACROSS THE CNTRL PLAINS TODAY AS A
60 TO 70 KT MID-LEVEL JET MAX APPROACHES THE REGION FROM THE
SOUTHWEST. AT THE BEGINNING OF THE PERIOD...AN MCS WITH ELEVATED
THUNDERSTORMS SHOULD BE ONGOING IN WRN KS WITH THIS CONVECTIVE
SYSTEM MOVING EWD ACROSS CNTRL AND ERN KS BY EARLY AFTERNOON. IN THE
WAKE OF THE MCS...STRONG DESTABILIZATION SHOULD OCCUR ALONG A MOIST
AXIS WITH SFC DEWPOINTS IN THE LOWER 70S F EXTENDING NNWWD FROM
CNTRL OK INTO WCNTRL KS. NAMKF FORECAST SOUNDINGS ALONG THIS
CORRIDOR BY 00Z SHOW EXTREME INSTABILITY IN CNTRL OK WITH MLCAPE
VALUES APPROACHING 5000 J/KG.
FURTHER NORTHWEST...MLCAPE VALUES DROP
INTO THE 3000 TO 4000 J/KG RANGE INTO NW KS. IN ADDITION...THE
MID-LEVEL JET MAX SHOULD MOVE OVER THE INSTABILITY AXIS DURING THE
LATE AFTERNOON
AND EARLY EVENING CREATING STRONG VERTICAL SHEAR
PROFILES WITH 0-6 KM SHEAR VALUES IN THE 50 TO 60 KT RANGE. THIS
ENVIRONMENT WILL BE A VERY FAVORABLE RAPID SUPERCELL DEVELOPMENT
ONCE SFC-BASED STORMS INITIATE JUST WEST OF THE MODERATE RISK AREA
IN THE LATE AFTERNOON OR EARLY EVENING. MODEL FORECASTS ARE IN
AGREEMENT ORGANIZING A CLUSTER OF INTENSE THUNDERSTORMS IN NRN KS
AND DRIVING A WELL-DEVELOPED MCS EWD ACROSS NERN KS INTO NRN MO
OVERNIGHT.

CONCERNING THE SEVERE THREATS...A 30 TO 40 KT LOW-LEVEL JET WILL
INCREASE FROM NRN OK INTO CNTRL KS DURING THE EARLY EVENING FEEDING
INTO SUPERCELLS ONGOING IN THE NRN PART OF THE MODERATE RISK AREA.
FORECAST SOUNDINGS AROUND HUTCHINSON KS AT 00Z SHOW IMPRESSIVE
LOW-LEVEL SHEAR WITH SUBSTANTIAL DIRECTIONAL SHEAR BELOW 800 MB AND
0-1 KM SHEAR VALUES OF 25 KT
. THIS COMBINED WITH LCL HEIGHTS AROUND
500 METERS
WILL BE FAVORABLE FOR TORNADOES WITH SUPERCELLS THAT
TRACK EWD ACROSS THE MODERATE RISK AREA. WITH THIS VERY FAVORABLE
ENVIRONMENT IN PLACE...THE POTENTIAL EXISTS FOR A FEW LONG TRACK
SUPERCELLS CAPABLE OF PRODUCING ISOLATED STRONG TORNADOES
. THE
CORRIDOR WITH THE GREATEST THREAT FOR STRONG TORNADOES SHOULD EXIST
FROM HAYS KS EWD ALONG THE I-70 CORRIDOR TO MANHATTAN KS AND SWD
ALONG THE I-35 CORRIDOR
. SUPERCELLS SHOULD BE MORE ISOLATED SWD INTO
FAR SRN KS AND NRN OK WHERE A CAPPING INVERSION WILL BE INCREASINGLY
INFLUENTIAL. SUPERCELLS THAT DEVELOP IN THIS STRONG INSTABILITY
SHOULD ALSO BE CAPABLE OF PRODUCING VERY LARGE HAIL. THE WIND DAMAGE
THREAT SHOULD BE FOCUSED FURTHER EAST ACROSS ERN KS INTO NW MO AS
THE MCS BECOMES WELL-DEVELOPED.

...NRN OZARKS/MID-MS VALLEY/SRN OH VALLEY...
AN AXIS OF MODERATE TO STRONG INSTABILITY IS FORECAST ACROSS MO
EXTENDING EWD INTO THE SRN OH VALLEY. MODEL FORECASTS AGREE WITH
DEVELOPING SCATTERED TO NUMEROUS THUNDERSTORMS BY LATE THIS
AFTERNOON. THIS DEVELOPMENT SHOULD BE STRONGLY TIED TO SFC HEATING.
FORECAST SOUNDINGS AT 21Z ACROSS SRN MO INTO WRN KY SHOW MODERATE
VERTICAL SHEAR PROFILES SUGGESTING ISOLATED SUPERCELLS AND/OR
ORGANIZED BOWING LINE-SEGMENTS WILL BE POSSIBLE. THE STRONG
INSTABILITY SHOULD BE ADEQUATE FOR LARGE HAIL WITH THE MORE INTENSE
STORMS. IN ADDITION...LOW-LEVEL LAPSE RATES WILL BE QUITE STEEP
SUGGESTING A THREAT FOR ISOLATED WIND DAMAGE WILL ALSO EXIST.

...NY/ERN PA/MD...
A WELL-DEFINED MOIST AXIS WILL BE IN PLACE TODAY FROM THE
MID-ATLANTIC NEWD ACROSS ERN PA INTO CNTRL NY. THE MODELS DEVELOP
MODERATE INSTABILITY ALONG THE CORRIDOR WITH STORMS INITIATING IN
THE HIGHER TERRAIN OF ECNTRL PA AND SRN NY. FORECAST SOUNDINGS LATE
THIS AFTERNOON ALONG THIS CORRIDOR SHOW 0-6 KM SHEAR VALUES IN THE
35 TO 40 KT RANGE SUGGESTING SHEAR WILL BE FAVORABLE FOR ORGANIZED
SEVERE STORMS. THE LATEST NAM AT 18Z SHOWS 0-3 KM LAPSE RATES OF 8.5
TO 9.5 C/KM SUGGESTING DOWNDRAFT MOMENTUM WILL BE QUITE EFFICIENT
AND FAVORABLE FOR WIND DAMAGE. HAIL WILL ALSO BE LIKELY WITH THE
MORE INTENSE CELLS GIVEN THE AMOUNT OF INSTABILITY FORECAST.

Joint Typhoon Warning Center

Tropical Disturbance Summary (0600z 09JUN)
=============================================
An area of convection (96W) located at 8.3N 134,1E or 70 NM north-northwest of Palau. Animated multispectral satellite imagery depicts poorly organized convection embedded within an easterly wave. A 0418z AMSU-B image supports the easterly wave near the surface, however the multispectral imagery shows an upper level circulation with weakening convection. Upper level analysis reveals the feature is encountering 20-30 knots of northeasterly vertical wind shear and is located under a region of weak convergence aloft.

Maximum sustained winds near the center is 10-15 knots with a minimum sea level pressure of 1011 mb. The potential for this disturbance to form into a significant tropical cyclone within the next 24 hours remains POOR.

System #2
=========
An area of convection (97W) located at 11.8N 113.7E or 390 NM south-southwest of Manila, Philippines. Animated multispectral satellite imagery depicts deep convection developing over a region of mid to upper level turning with tight surface troughing. A 0221z TRMM image indicates that the convection has started to wrap towards the center of the mid-level turning. Upper level analysis indicates a point source providing good outflow with moderate to high vertical wind shear hampering development.


Maximum sustained winds near the center is 10-15 knots with a minimum sea level pressure of 1010 mb. The potential for this disturbance to form into a significant tropical cyclone within the next 24 hours is POOR

With a developing ridge with alot of dry air in the GOM this week and into the weekend..the mid-level and surface trough-low will enter a region of higher shear and dry air coming down from the GOM..this dry air and rising pressures in the carribean from also a ridge building in from the eastern Carribean will null this from really forming. There is still a small window if it gets north of Cuba near the bahamas by the weekend..but right now models arent showing this. I would though look around the bahamas next week or next weekend..maybe from this or something else.


Well the Caribbean ridge will provide a low-shear environment, and doesn't really raise the surface pressures. Doesn't seem too dry in the southern Caribbean 6 days from now:

Well the model is pointing out another possibility that could happen. Sometimes surface lows will form under upper lows in the tropics and develop. That is less likely than the other options in this situation. If it were to occur, development of the system would be very slow.
