Contest! First Fun-derstorm Day

[Ptarmigan]

Did anyone hear thunder around 1:00 AM last night. I thought I did.

[wxdata]

Slight Risk edged a little closer to SE TX; still severe threat highest east of here on Saturday.

"ALTHOUGH A MARGINAL SEVERE THREAT MAY BE ONGOING WITH
THE THUNDERSTORMS IN EAST TX SATURDAY MORNING...THE GREATER THREAT
SHOULD EXIST FURTHER EAST AS STORM COVERAGE INCREASES LATE SATURDAY
AFTERNOON. "

Houston NWS
"EXTENSIVE CLOUD COVER WILL LIMIT
HEATING AND INSTABILITY AND ONLY MODERATE SHEAR SO SEVERE THREAT
LOOKS LOW AT THIS TIME. "

AREAS AFFECTED...WEST CENTRAL TX INTO THE EDWARDS PLATEAU

CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY

VALID 192352Z - 200145Z

ISOLATED STRONGER STORMS WILL REMAIN POSSIBLE EARLY THIS EVENING
/02-03Z/ ACROSS WEST CENTRAL TX SWD INTO THE EDWARDS PLATEAU...WITH
HAIL BEING THE PRIMARY THREAT. A FEW STORMS MAY PRODUCE HAIL TO
AROUND 1 INCH...BUT LIMITED COVERAGE WILL PRECLUDE THE NEED FOR A
WATCH. STRONG WINDS WILL ALSO BE POSSIBLE.

AT 2345Z...REGIONAL RADARS SHOWED A STRONG TSTM LOCATED OVER FISHER
COUNTY TX...WITH THIS TSTM LOCATED NEAR THE INTERSECTION OF A SSEWD
MOVING COLD FRONT AND A SWD EXTENDING DRY LINE. ADDITIONAL STORMS
ARE EXPECTED TO DEVELOP SWD INTO THE EDWARDS PLATEAU AS THE DRY
LINE/COLD FRONT INTERSECTION TRANSLATES SWD WITH THE SSEWD MOVEMENT
OF THE COLD FRONT. MODIFIED RUC SOUNDINGS ACROSS WEST CENTRAL TX
/WITH SURFACE INFLOW DEWPOINTS AROUND 50 F AND STEEP MID LEVEL LAPSE
RATES AROUND 8 C/KM/ SUGGEST MUCAPE AROUND 700 J/KG. THIS COMBINED
WITH EFFECTIVE BULK SHEAR OF 30-35 KT SUPPORTS BOTH MULTICELL AND
SUPERCELL STRUCTURES. THE SSEWD MOVING COLD FRONT SHOULD UNDERCUT
MOST ACTIVITY ONCE IT DEVELOPS WITH STRONG WINDS BEING AN ADDITIONAL
THREAT WITH THE INITIAL PHASE OF THE STORMS.
