The episode as NWS GJT wrote it up.
There was some relief in the drought situation in September. The U.S. Drought Monitor indicated an improvement from "severe drought" to "abnormally dry" conditions across small portions of east central and southeast Utah. Otherwise, conditions remained about the same as long term drought over the past several years still caused concerns about water supply and stressed vegetation. For a continuation on this drought situation please see the October 2006 Storm Data publication.

SCATTERED SHOWERS AND THUNDERSTORMS WERE ONGOING OVER THE SOUTHERN ...CENTRAL AND NORTHERN MOUNTAINS WITH ISOLATED ACTIVITY IN THE HIGHER CENTRAL AND SOUTHWEST VALLEYS. A BROAD TROF ACROSS THE NORTH WITH A SURFACE FRONT JUST SOUTH OF CAG WAS THE FOCUS OF ACTIVITY IN NORTHWEST COLORADO. MEANWHILE...A WEAK JET MAX ACROSS THE FOUR CORNERS WAS PROVIDING SUPPORT FOR TSTMS IN THE SOUTH. TONIGHT: LIFT DIMINISHES AS UPPER TROF AXIS SHIFTS EAST OF THE CONTINENTAL DIVIDE THIS EVENING. CONCURRENT DIURNAL COOLING AND SHIFT IN JETLET ACROSS THE SOUTH WILL LEAD TO SIMILAR LOSS OF UPWARD FORCING. THEREFORE...EXCEPT FOR ISOLATED SHOWERS LATER TONIGHT FORECAST AREA WILL REMAIN DRY. SOUTHEASTWARD SHIFT IN MOVEMENT OF THE UPPER LOW WILL ALLOW THE COLD FRONT TO SLOWLY SINK SOUTH RESULTING IN COOLER OVERNIGHT LOWS...ESPECIALLY ACROSS THE NORTH. FRIDAY-SATURDAY: CAA WILL CONTINUE ON FRIDAY AS THE LOW CONTINUES EASTWARD OVER THE HIGH PLAINS. COLD AIR SURGING SOUTHWARD ALONG THE EASTERN PLAINS WILL RESULT IN A PUSH OF MOISTURE AGAINST THE EASTERN EDGE OF THE CONTINENTAL DIVIDE. DRIER AIR ON THE BACKSIDE OF THE LOW WILL FILL IN OVER THE CWFA LIMITING TSTMS TO THE CONTINENTAL DIVIDE. THIS SCENARIO WILL CARRY OVER INTO SATURDAY. AS A RESULT... HIGHS AND LOWS WILL RUN 5 TO 10 DEGREES COOLER THAN OVER THE PAST FEW DAYS OR NEAR GUIDANCE VALUES. .LONG-TERM (SATURDAY NIGHT THROUGH THURSDAY)... HIGH PRESSURE WILL DOMINATE THE CWFA THROUGHOUT THE END OF THE WEEKEND AND THE FIRST HALF OF THE NEW WORK WEEK. A DRY NORTHWESTERLY FLOW WILL KEEP THE NORTHERN AREA RELATIVELY DRY. HOWEVER WITH AN INCREASE IN SOUTHERLY MOISTURE, SOME FROM HURRICANE JOHN WILL KEEP A DAILY CHANCE OF CONVECTION ACROSS THE SOUTHERN MOUNTAINS. THIS MOISTURE LOOKS TO BEGIN TO CREEP INTO THE NORTHERN AREAS BY THURSDAY. TEMPERATURES LOOK TO BE AT OR SLIGHTLY ABOVE NORMAL LEVELS IN THE NORTH. SLIGHTLY BELOW NORMAL IN THE SOUTH DUE TO INCREASED CLOUD COVER. && .GJT WATCHES/WARNINGS/ADVISORIES... .CO...NONE. .UT...NONE. NL/BA
