The episode as NWS AFC wrote it up.
A strong thunderstorm moved off the Alaska Range and merged with a weaker thunderstorm that moved off the Talkeetna Mountains 10 miles east of Talkeetna. A spotter reported golf ball size hail and trees blown down along with flooding basements of a couple of local businesses, but this did not result in any property damage. Damage in the Talkeetna area was inconsequential, primarily some flower gardens were destroyed. The storm also produced marble sized hail at the McKinley Princess Lodge along the Chulitna River and resulted in interrupted phone and television service through Friday June 17th.

AREA FORECAST DISCUSSION SOUTHCENTRAL AND SOUTHWEST ALASKA 500 PM ADT WED JUN 15 2005 .DISCUSSION... THE OMEGA BLOCK OVER THE MAINLAND WILL PERSIST THROUGH THE END OF THIS WEEK BEFORE SLOWLY BEING PUSHED OFF TO THE EAST THIS WEEKEND. THEREFORE, NO MAJOR CHANGES IN THE SHORT TERM FORECAST ARE EXPECTED. MAIN CONCERNS REMAIN THE CONVECTIVE POTENTIAL OVER THE INLAND REGIONS ALONG THE THERMAL TROUGH EXTENDING ALONG THE ALASKA RANGE TO THE LOWER YUKON VALLEY. THUNDERSTORMS HAVE ALREADY STARTED IN THE NORTHEAST KUSKOKWIM VALLEY AND ALONG THE ALASKA RANGE FROM WINDY PASS EAST. THE REMNANTS OF THE THUNDERSTORMS OVER THE CENTRAL AND WESTERN KUSKOKWIM VALLEY APPEAR TO BE SHADING THAT REGION TODAY AND THUS INHIBITING THE CONVECTIVE DEVELOP. CONDITIONS APPEAR TO REMAIN SIMILAR THURSDAY WITH REGARD TO CONVECTIVE POTENTIAL. THE VERTICAL TOTALS AND K-INDEX ALONG WITH CAPE CONTINUE TO SUPPORT A VERY GOOD POSSIBILITY OF THUNDERSTORMS IN THE COPPER RIVER BASIN THURSDAY WITH A MORE LIMITED CHANCE OF THUNDERSTORMS AS YOU MOVE WEST TO THE KUSKOKWIM VALLEY. FURTHER WEST WE HAVE THE LARGE LOW TRACKING TO THE CENTRAL ALEUTIANS WITH THE ASSOCIATED FRONT OUT IN ADVANCE OF THIS LOW THROUGH THE UNALASKA AREA. WIND IS NOT A MAJOR FACTOR WITH THIS LOW, MAINLY SMALL CRAFT CONDITIONS OR LOWER. POST FRONTAL CONDITIONS HAVE SIGNIFICANT LOW CLOUDS AND LIGHT RAIN OR DRIZZLE, SO THE MAIN ISSUE WILL BE IN THE AVIATION REALM. LOW CEILINGS AND VISIBILITIES WILL BE THE PROBLEM AREAS FOR THE ALEUTIANS FROM CAPE SARICHEF WEST. THE FRONT IS SLOWLY MOVING EAST BUMPING INTO THE BLOCKING RIDGE AND WEAKENING. WE EXPECT THE FRONT TO BE ALONG THE BERING SEA COAST LATE THURSDAY NEARLY DISSIPATED. IN THE LONGER TERM A WAVE FORMING SOUTH OF THE MAIN LOW WILL BE MOVING NORTHEAST ALONG THE WEAK FRONTAL BOUNDARY TO THE SAND POINT AREA FRI EVENING. THIS LOW IS SPAWNING OFF OF A TROPICAL STORM NOW OFF OF THE JAPANESE COAST AND SHOULD HAVE AMPLE MOISTURE WITH IT. BY SATURDAY THE MOISTURE TRAIN ASSOCIATED WITH THIS LOW EXTENDS 1800 MILES TO THE SOUTHWEST. THE MAIN PROBLEM WITH THE EXTENDED FORECAST IS A TIMING DIFFERENCES BETWEEN THE GFS AND MESO-ETA. THE GFS IS MUCH FASTER IN THE MOVEMENT OF THE LOW AND FRONT HAVING THE FRONT THROUGH SOUTH CENTRAL ALASKA FRI NIGHT AND SATURDAY WHILE THE MESO ETA IS JUST GETTING THE FRONT INTO SOUTH CENTRAL ALASKA SAT AFTERNOON. ONE WOULD NORMALLY EXPECT THE LOW TO PROGRESS SLOWLY SINCE WE HAVE A BLOCKING RIDGE, BUT THIS SYSTEM IS OF TROPICAL ORIGIN AND THEY TYPICALLY HAVE ENOUGH ENERGY TO DISPLACE THE RIDGE. EITHER WAY, WE EXPECT THE PATTERN TO SHIFT FOR THE WEEKEND FROM THE PREVAILING HOT DRY PATTERN TO A MORE COOL MOIST PATTERN. .AER/ALU...WATCH/WARNING SUMMARY PUBLIC...NONE. MARINE...NONE.
