Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

NWS Anchorage, AK wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 29, 12:00 AM AKDT, 32 minutes earlier.

AREA FORECAST DISCUSSION SOUTHWEST ALASKA
500 AM ADT TUE JUN 29 2004
.DISCUSSION...

ANOTHER VERY ACTIVE EVENING AND EARLY MORNING OF THUNDERSTORMS ACROSS
THE SOUTHCENTRAL PORTION OF THE STATE. NUMEROUS PRODUCTS WERE ISSUED
OVERNIGHT INCLUDING A FEW SEVERE THUNDERSTORM WARNINGS. DOPPLER RADAR
CROSS-SECTIONS ALONG WITH DBZ LAYER COMPARISONS INDICATED SEVERAL
HAIL PRODUCING STORMS AND IMPRESSIVE RETURNS WELL ABOVE 35 THOUSAND
FEET. RADAR RAINFALL ESTIMATES WERE UP TO AN INCH OVER THE SUSITNA
VALLEY.

GENERAL HEMISPHERIC PATTERN KEEPS THE ANCHOR LOW NEAR THE POLE FOR
THE WEEK AND THE THERMAL TROUGH OVER MUCH OF THE ALASKAN INTERIOR.
OVER THE ALASKA PENINSULA AND POINTS WEST...AN UPPER-LEVEL LOW MOVES
FROM SOUTH OF THE CHAIN INTO THE ALEUTIANS.

TODAY PROMISES TO PROVIDE MORE ACTIVE WEATHER AS THE MESOETA IS
SHOWING -7.5 LI ALONG A THETA-E RIDGE WITH CAPE VALUES OF 2000+. THE
SETUP IS SIMILAR TO LAST NIGHT SO STORMS WILL LIKELY FIRE IN MANY OF
THE SAME LOCATIONS. ONLY CAUTION IS VORTICITY ADVECTION AND Q-VECTORS
ARE VERY WEAK AND NOT FAVORABLE. IT DOES APPEAR THAT ANCHORAGE WILL
BE A BIT TOO FAR SOUTH OF THE THUNDERSTORM FOR TODAY.

OUT WEST...GENERAL WEAK EASTERLY FLOW REMAINS OVER THE AREA. 500 MB
LOW SOUTH OF THE ALEUTIANS WILL CONTINUE TO MOVE TO THE NORTH AND
HELP TO STEER MID-LEVEL MOISTURE TO THE ALASKA PENINSULA WEST. RAIN
AND LOW CLOUDS A GOOD BET IN MUCH OF THAT AREA.

FOR THE EXTENDED...NO MAJOR SYSTEMS FORECAST TO COME INTO THE STATE.
CALMER SKIES ARE IN STORE AS MOST PLACES WILL SEE A COOLING TREND AND
AN EASING OF THE THERMAL TROUGH.

.AER/ALU...WATCH/WARNING SUMMARY
PUBLIC...NONE.
MARINE...NONE.
FIRE WEATHER...NONE.
