In navolging van een eerdere berichten over tornado's in de VS...
In het grensgebied Texas/Oklahoma is de boel aan het exploderen. Hieronder drie satpics genomen binnen tijdspanne van een half uur: tussen 22u45 en 23u15 onze tijd.
Prachtige ingezoomde animaties van het gebied zijn te zien op
http://wwwghcc.msfc.nasa.gov/GOES/goeseastconus.html
Uit de dynamiek van de bewolking op dergelijke bewegende beelden lijk je zo de windshear te herkennen. Wat is internet toch prachtig, met onze neus op de feiten
...TX/OK...
MESOSCALE PARAMETERS ARE EVOLVING THIS AFTERNOON WITHIN THE MODERATE
RISK AREA FOR A WIDESPREAD THREAT FOR SUPERCELLS WITH VERY
LARGE...DESTRUCTIVE HAIL AND TORNADOES/DAMAGING WINDS.
ANIMATED VIS IMAGERY COMBINED WITH EARLY AFTERNOON SURFACE
MESOANALYSES INDICATED A DRY LINE OVER WRN TX WITH A COUPLE OF
GENERALLY E-W ORIENTED CONVECTIVE OUTFLOW BOUNDARIES ACROSS OK AND
NWRN TX AND INTO THE OK/TX PANHANDLES. FOR ADDITIONAL INFORMATION
ON MESOSCALE ANALYSIS DETAILS...PLEASE REFER TO SPC MESOSCALE
DISCUSSION #858 AND OTHER RELEVANT MESOSCALE DISCUSSIONS AND
WATCHES.
18Z SOUNDINGS/OBJECTIVE ANALYSES INDICATED A VERY UNSTABLE AIR MASS
OVER NWRN TX. MODERATE INSTABILITY SURROUNDS THIS REGION FROM THE
TX PANHANDLE INTO WRN OK AND SWD WHERE A SECOND AREA OF VERY STRONG
INSTABILITY EXISTED ALONG THE TX BIG BEND REGION. STRONG DEEP LAYER
SHEAR /45-55 KT/ ASSOCIATED WITH A 40-50 KT WLY MID LEVEL SPEED MAX
IN THE BASE OF THE MID LEVEL TROUGH COMBINED WITH STEEP LAPSE RATES
WILL SUPPORT SUPERCELLS. GIVEN THE VERY UNSTABLE AIR MASS...VERY
LARGE...DESTRUCTIVE HAIL AND TORNADOES WILL BE LIKELY.
