Electrifying!

We may not have any storms, but apparently someone has had some doozies!

This storm pictures was taken yesterday morning in Cape Town, South Africa.

It was sent to me by Linda Vanreenan. She lives here in Amarillo, but has friends and family in Cape Town and knows my passion for lightning photos.

Thanks Linda!

Nothing severe but maybe photogenic storms?

ACROSS PARTS OF OK AND THIS AREA WILL BE ADDED TO THUNDER AS WELL.

FARTHER NORTH ACROSS THE UPPER MS VALLEY...WELL DEFINED UPPER
VORT/SHORTWAVE TROUGH IS SHEARING EAST ACROSS MANITOBA INTO NWRN
ONTARIO. THUNDERSTORMS ARE DEVELOPING SWWD ALONG TRAILING COLD
FRONT INTO NWRN MN/NERN ND AND THIS ACTIVITY SHOULD SPREAD ACROSS

ANOTHER QUIET CONVECTIVE DAY IS EXPECTED TODAY ACROSS MUCH OF THE
UNITED STATES AS STRONG WESTERLIES ARE CONFINED TO THE NORTHERN TIER
OF STATES...AND RICH LOW LEVEL MOISTURE ONLY RESIDES OVER THE
SOUTHEAST REGION. SCATTERED AFTERNOON THUNDERSTORMS ARE EXPECTED
OVER THE GULF COAST STATES IN ASSOCIATION WITH BROAD UPPER LOW OFF

RATES WILL COMBINE WITH MARGINAL VERTICAL SHEAR TO SUPPRESS
ORGANIZED SEVERE STORMS.

WEAK EASTERLY/UPSLOPE LOW LEVEL FLOW IS FORECAST TO DEVELOP OVER
WESTERN NEB AND EASTERN WY THIS AFTERNOON. THIS WILL HELP TO
TRANSPORT SLIGHTLY MORE MOIST AND UNSTABLE AIRMASS INTO HIGHER

MODELS DEVELOP SCATTERED STORMS. THESE STORMS MAY DEVELOP EASTWARD
INTO WESTERN NEB DURING THE EVENING. WEAK FLOW ALOFT WILL RESULT IN
