NESDIS IS CONTINUING TO ACCEPT APPEALS ON THE RETIREMENT OF THE SPENES
PRODUCT.  APPEALS CAN BE SUBMITTED BY EMAILING JOHN.SIMKO@NOAA.GOV
.
EVENT...MOIST CONVEYOR BELT..SHORT WAVE ENERGY AND DEFORMATION FOR STEADY
LIGHT TO MODERATE/LOCALLY HVY ESPECIALLY UPSLOPE TERRAIN...
.
SATELLITE ANALYSIS AND TRENDS...AS PER GOES WATER VAPOR LOOP UPPER LEVEL
(500MB?)  LOW APPEARED TO BE NEAR  NORTH CENTRAL COLORADO NEAR THE
WYOMING BORDER AND TO THE NORTH FURTHER INTO WYOMING AT A LOWER LEVEL
LIKE 700MB.  IN ANY CASE LOW IS STEERING MOIST CONVEYOR BELT FROM S
TX/WESTERN GULF NORTHWARD THROUGH THE PLAINS AND WESTERN MS VALLEY AND
THEN BACK WEST ACROSS N NEBRASKA/S SOUTH DAKOTA INTO AREA CENTERED ON
CENTRAL WYOMING.  SHORT WAVE TAIL OUT AHEAD OF UPPER LEVEL LOW/TROUGH
WAS LIFTING NORTH THROUGH WESTERN NEBRASKA WITH DIFFLUENCE OUT AHEAD
PRODUCING SHOWERS/STEADY RAIN, BUT MOVING SLOWLY THROUGH NW NEBRASKA
AND SW SD MORE CONCERN FOR REST OF THE MORNING).  MORE OF A PROBLEM WITH
UPSLOPE, DIFFLUENCE/DEFOMATION WITH MOIST CONVEYOR BELT WAS WYOMING AND
ESPECIALLY CENTERED IN FREMONT AND W NATRONA...WHERE RAIN RATES CAN BE
REACHING 0.1"-0.3"/HR ISOLATED HIGHER (0.5") ESPECIALLY IN UPSLOPE AREAS.
UPPER LEVEL LOW MOVING VERY SLOW IN RESPONSE TO NOT A WHOLE LOT UPSTREAM
TO KICK IT OUT...SO WOULD BE MOST CONCERN FOR POSSIBLE FLOOD THREAT FROM
PERSISTENT STEADY PRECIP.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
.
SHORT TERM OUTLOOK VALID 1245-1545Z...MEDIUM TO HIGH CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...CENTRAL WYOMING CENTRERED ON FREMONT AND FOR THE
NEXT 2-3HRS WESTERN NATRONA COUNTY AND LIGHTER FRINGE COUNTIES OF HOT
SPRINGS, S WASHAKIE, AND NORTHERN SWEETWATER COUNTY WITH MOIST CONVEYOR
BELT ADVECTION DEEP MOISTURE INTO THE AREA.   TO THE EAST...SHORT WAVE
ROTATING NORTH WITH A BIT MORE MOVEMENT TO STEADY RAIN, BUT SLIGHTLY
HIGHER RAIN RATES ESPECIALLY INTO SW SOUTH DAKOTA AND UPSLOPE TERRAIN
AREAS FOR AN UPTICK IN FLOOD THREAT.  THOUGH PWAT MOISTURE AT RAP AND RIW
RAOB SITES THIS MORNING NOT QUITE IN THE TOP 50 FOR MONTH OF MAY...WAS
WELL ABOVE NORMAL WITH CONTINED MOISTURE ADVECTION AND FORCING ON WET
SOILS TO HEIGHTEN FLOOD THREAT THIS PERIOD AND EVEN THROUGHOUT THE DAY.
