AREA FORECAST DISCUSSION FOR WESTERN SD AND NORTHEASTERN WY
NATIONAL WEATHER SERVICE RAPID CITY SD
443 PM MDT THU APR 24 2014

.SHORT TERM...THIS EVENING THROUGH FRIDAY NIGHT
ISSUED AT 232 PM MDT THU APR 24 2014

DEEP UPPER TROUGH WILL CONTINUE TO DIG INTO THE 
WESTERN CONUS...WITH MEAN HEIGHT RISES PUSHING EAST INTO THE 
NORTHERN PLAINS THROUGH FRIDAY. TWO WEAK IMPULSES WILL EJECT OUT OF 
THE MEAN UPPER UPPER LOW...AND INTO THE REGION...POSSIBLY SUPPORTING 
A FEW SHOWERS ACROSS THE NW HALF OF THE FA...ESP FRI NIGHT. WAA 
ONGOING ACROSS THE REGION TODAY...AND WILL CONTINUE THROUGH FRIDAY 
AHEAD OF THE DEEP UPPER TROUGH. SFC PRESSURE FALLS EXPECTED THROUGH 
THE PERIOD WITH WINDS SHIFTING SE AND INCREASING PER LEE SIDE 
TROUGHING...WHICH WILL BE ENHANCED BY THE APPROACHING UPPER 
LOW.

TONIGHT...WEAK ELEVATED THETA-E ADV /EVIDENCED WELL AT H7/ WILL 
SUPPORT AN AREA OF WEAK LIFT ACROSS THE NW ZONES THIS 
EVENING...POSSIBLY SUPPORTING A FEW SPRINKLES WHEN COUPLED WITH A 
WEAK UPPER LEVEL IMPULSE. DRY LL PROFILES AND LACK OF SUFFICIENT 
MOISTURE PRECLUDES A SHRA MENTION. OTHERWISE...EXPECT INCREASING 
HIGH CLOUDS THROUGH THE PERIOD...WITH LOWS GENERALLY IN THE 30S /40S 
IN THE LEE OF THE BH/.

FRIDAY...SW FLOW WITH INCREASING ELEVATED MOISTURE WILL SUPPORT 
SCT-BKN MID AND HIGH CLOUDS...ESP IN THE AFTERNOON/EVENING. STILL 
EXPECTING ENOUGH INSOLATION TO SUPPORT FAIRLY DEEP MIXING...PUSHING 
TEMPS INTO THE 70S MOST PLACES. DEEP MIXING OVER THE HIGHER TERRAIN 
OF NE WY AND THE WESTERN BH WITH INCREASING MID LEVEL MOISTURE 
COUPLED WITH AN ADVANCING UPPER LEVEL IMPULSE MAY BE SUFFICIENT FOR 
A FEW ISOLD HIGH BASED SHRA THERE LATE FRI AFTERNOON. NAM LI/S 
CERTAINLY HINT AT THIS AND A FEW HIRES MODELS DO GENERATE 
CONVECTION. HAVE ADDED A LOW POP FOR THIS. SLIGHTLY BETTER CHANCES 
FOR SHRA ARRIVE LATER FRIDAY NIGHT...MAINLY THE NW HALF...ALBEIT 
ONLY ISOLD TO SCT. HAVE RETAINED A SHRA MENTION FRIDAY 
NIGHT...SHIFTING THE HIGHER CHANCES AFTER MIDNIGHT. INCREASING SFC 
PRESSURE FALLS WILL HELP MAINTAIN A PARTIALLY MIXED BL THROUGH THE 
NIGHT MOST PLACES...WITH LOWS IN THE 40S EXPECTED MOST PLACES. HAVE 
BUMPED LOWS UP A COUPLE DEGREES.    

&&

.LONG TERM...SATURDAY THROUGH THURSDAY
ISSUED AT 232 PM MDT THU APR 24 2014

UPPER LEVEL TROUGH WILL MOVE OVER THE ROCKIES ON 
SATURDAY. SURFACE LOW OVER EASTERN CO WILL CREATE BREEZY SOUTHEAST 
WINDS...ESPECIALLY ACROSS CENTRAL SD...BRINGING IN WARM AND MOIST 
AIR. INSTABILITY AND MOISTURE INFLUX WILL ALLOW SHOWERS AND 
THUNDERSTORMS TO DEVELOP SATURDAY AFTERNOON AND EVENING AS THE LOW 
APPROACHES. HIGHS ON SATURDAY WILL BE IN THE LOWER 60S TO LOWER 70S. 

TRACK OF THE UPPER LOW IS STILL UNCERTAIN AT THIS POINT...WITH THE 
GFS BRINGING IT INTO SD SUNDAY NIGHT AND THE ECMWF KEEPING IT 
FARTHER SOUTH IN NEBRASKA. BOTH WRAP COOLER AIR BACK INTO THE CWA 
BEHIND THE LOW...BUT TEMPS SHOULD STAY WARM ENOUGH FOR THE EVENT TO 
BE MAINLY RAIN...ESPECIALLY ON THE SD PLAINS. SNOW IS MORE POSSIBLE 
ACROSS NORTHEAST WYOMING AND THE BLACK HILLS WHERE LOWS DIP BELOW 
FREEZING SUNDAY AND MONDAY NIGHTS. ALSO HAVE SOME ISOLATED 
THUNDERSTORMS IN THE FORECAST ACROSS CENTRAL SD WHERE INSTABILITY IS 
BETTER. 

MODELS ARE INDICATING THAT WHEN THE UPPER LOW SHIFTS 
EASTWARD...ENERGY NORTHEAST OF IT WILL BE TAKEN IN AND CIRCULATED 
BACK AROUND THE LOW...SLOWING IT DOWN AND ACTUALLY CAUSING THE 
SYSTEM TO RETROGRADE. THEREFORE...PRECIPITATION AND COOL WEATHER MAY 
STICK AROUND FOR THE FIRST HALF OF THE WEEK. OVERALL THE SYSTEM 
LOOKS VERY MOIST...WITH PWATS 180-200% OF NORMAL. MANY AREAS MAY 
RECEIVE MORE THAN AN INCH OF QPF...WITH THE BLACK HILLS POSSIBLY 
RECEIVING MORE THAN TWO INCHES. ADDED MODERATE PRECIPITATION WORDING 
IN THE WEATHER GRIDS.

.AVIATION...FOR THE 00Z TAFS THROUGH 00Z FRIDAY EVENING
ISSUED AT 441 PM MDT THU APR 24 2014

WINDS WILL BECOME LIGHT AND VARIABLE THIS EVENING. VFR 
CONDITIONS ARE EXPECTED THROUGH THE PERIOD.
