AREA FORECAST DISCUSSION

955 AM CDT MON APR 8 2013

.UPDATE...
ISSUED AT 944 AM CDT MON APR 8 2013

UPGRADING TO WINTER STORM WARNING FOR HEAVY SNOW SOUTHWEST
COUNTIES OF GOLDEN VALLEY...BILLINGS...STARK...DUNN...HETTINGER
MCKENZIE...SLOPE. RADAR ANS SURFACE REPORTS SHOW BAND OF HEAVY
SNOW WILL EXTEND ACROSS THE SOUTHWEST. MOST OF THE HEAVY SNOW WILL
FALL THROUGH EARLY AFTERNOON THEN BEGIN TO DIMINISH.

UPDATE ISSUED AT 650 AM CDT MON APR 8 2013

SURFACE OBSERVATIONS AT STANLEY...MINOT AIR FORCE BASE AND BELCOURT
ARE INDICATING FREEZING RAIN. ALSO A REPORT OF FREEZING RAIN AND
SLEET AT LANSFORD. FORECAST SOUNDINGS INDICATE THIS SHOULD BE A
SHORT LIVED EVENT...WITH COLUMN CONTINUING TO COOL. THERE WAS ALSO
RAIN LAST NIGHT THAT HAS NOW FROZEN TO SURFACES. WILL ISSUE A
FREEZING RAIN ADVISORY TO COVER THE ICY CONDITIONS THROUGH THE
MORNING COMMUTE. WILL GO THROUGH NOON AND LET THE DAY SHIFT CANCEL
IF NEEDED.

SNOW CONTINUES TO LIFT NORTH AND EAST THROUGH SOUTHWEST NORTH
DAKOTA. NO CHANGES TO THE SNOW AND BLOWING SNOW ADVISORY.

&&

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 408 AM CDT MON APR 8 2013

THE MAIN FORECAST CHALLENGE FOR THE SHORT TERM PERIOD IS THE
UPCOMING STORM SYSTEM SET TO IMPACT WESTERN AND CENTRAL NORTH DAKOTA
TODAY AND INTO TONIGHT. ADDITIONALLY...WINTER WEATHER HEADLINES WILL
NEED TO EVALUATED IN ORDER TO DETERMINE WHETHER OR NOT CHANGES ARE
WARRANTED.

THE 00Z MODEL GUIDANCE CONTINUES TO HAVE SOME DISAGREEMENT REGARDING THE
AMOUNT OF QPF OVER THE IMPACTED AREA...INTRODUCING UNCERTAINTY INTO
THE QPF AND TOTAL SNOWFALL FORECAST. THE 00Z NAM/GFS ARE SIMILAR IN
THEIR SOLUTIONS PAINTING HEAVIER QPF AMOUNTS ACROSS THE SOUTHWEST
AND PARTS OF THE CENTRAL... WHILE THE 00Z ECMWF/GEM ARE
DRIER...KEEPING THE HEAVIEST QPF AMOUNTS FURTHER SOUTH OVER SOUTH
DAKOTA. IN REGARDS TO TIMING...ALL MENTIONED MODEL GUIDANCE HAS THE
HEAVIEST SNOWFALL OCCURRING BETWEEN 12Z AND 00Z TUESDAY. SNOWFALL
INTENSITY WILL DECREASE FROM NORTH TO SOUTH AFTER 00Z...AS LIGHT
SNOW ENDS AFTER 06Z TUESDAY. HOWEVER...ALONG THE ND/SD STATE
BORDER...LIGHT SNOW WILL CONTINUE THROUGH THE END OF THE PERIOD...AS
A SHARP PRECIPITATION GRADIENT SETS UP.

THE 00Z NAM/GFS...12Z ECMWF...AND THE LATEST RAP RUN AGREE ON THE
OVERALL THERMAL PROFILE. A COLD FRONT IS FORECAST TO DROP
SOUTH OUT OF CANADA...WITH COLDER H850 TEMPERATURES OF -10 TO -14 C
FORECAST TO MOVE OVER THE AREA. TEMPERATURES REMAIN FAIRLY WARM THIS
MORNING...MOSTLY ABOVE FREEZING FOR LOCATIONS ACROSS THE
SOUTHWEST...WHERE PRECIPITATION WILL BE INITIALLY LIGHT RAIN. A
QUICK TRANSITION TO SNOW WILL OCCUR BY DAYBREAK AS TEMPERATURES COOL
QUICKLY ACROSS THE SOUTHWEST.

AFTER WADING THROUGH THE 00Z MODEL GUIDANCE...HAVE DECIDED TO LEAN
MORE TOWARDS THE ECMWF SOLUTION...AS IT HAS HAD MORE RUN TO RUN
CONSISTENCY THAN THE NAM/GFS/GEM AS WELL AS HAVING SUPERIOR
PERFORMANCE THIS PAST WINTER. GIVEN THE AMOUNT OF UNCERTAINTY THAT
REMAINS AS THIS EVENT IS JUST GETTING UNDERWAY...HAVE DECIDED TO
KEEP WINTER WEATHER HEADLINES AS IS. SERIOUS CONSIDERATION WAS
GIVEN TO THE ISSUANCE OF A WINTER STORM WARNING FOR SNOW FOR
GOLDEN VALLEY...BILLINGS...DUNN...STARK...AND SLOPE COUNTIES WHERE
THE GREATEST SNOWFALL TOTALS ARE EXPECTED TO OCCUR.
ALSO...CONSIDERATION WAS GIVEN TO EXPANDING THE CURRENT ADVISORY
FURTHER EAST. HOWEVER...THE ISSUANCE OF A WARNING AND THE
EXPANSION OF THE CURRENT ADVISORY DID NOT SEEM FEASIBLE GIVEN LOW
CONFIDENCE AND HIGH UNCERTAINTY BEYOND THE CURRENT WINTER WEATHER
HEADLINES. WILL ALLOW DAY SHIFT TO REEVALUATE AND CONSIDER THESE
OPTIONS.

.LONG TERM...(TUESDAY THROUGH SUNDAY)
ISSUED AT 408 AM CDT MON APR 8 2013

THE MAIN FORECAST PROBLEM EARLY IN THE EXTENDED PERIOD WILL BE
PRECIPITATION CHANCES ALONG THE NORTHERN PERIPHERY OF THE LARGE
SYSTEM OVER THE CENTRAL AND NORTHERN PLAINS...IN ADDITION TO
TEMPERATURES UNDER COLD HIGH PRESSURE TO THE NORTH OF THE SYSTEM. A
PROGRESSIVE WEST TO NORTHWEST UPPER FLOW WILL DEVELOP BY LATE IN THE
WORK WEEK AND THROUGH THE WEEKEND BRINGING PERIODIC CHANCES OF MIXED
PRECIPITATION.

TUESDAY AND WEDNESDAY SHOULD BE QUIET ACROSS ALL BUT THE FAR SOUTH.
COLD SURFACE HIGH PRESSURE OVER SOUTHERN CANADA INTO THE NORTH
DAKOTA SHOULD KEEP THE NORTH DRY. DETERMINISTIC MODELS KEEP THE
NORTHERN EDGE OF THE STRONG SYSTEM NEAR THE SOUTH DAKOTA BORDER. THE
GEM/ECMWF KEEP SOME LIGHT QPF ALONG THE SOUTHERN TIER COUNTIES WHILE
THE GFS KEEPS PRECIPITATION SOUTH OF THE STATE. LOWERED TEMPERATURES
A BIT FROM PREVIOUS FORECAST...WITH LESS SKY COVER...COLDER MID
LEVEL TEMPERATURES AND REMAINING SNOWPACK...THE FAR NORTHERN
COUNTIES SHOULD SEE SOME LOWER TEENS AND SINGLE DIGITS FOR OVERNIGHT
LOWS. FAVOR A EC/GEM SOLUTION AS FAR AS PRECIPITATION ON TUESDAY AND
WEDNESDAY...THUS WILL KEEP POPS ALONG THE SOUTH DAKOTA BORDER
THROUGH THE PERIOD. AT THIS TIME...WILL NOT BRING A SIGNIFICANT
AMOUNT OF QPF TO THE SOUTH...HOWEVER...THERE IS A VERY SHARP CUTOFF
ON THE NORTHERN EDGE OF THE DEFORMATION ZONE. A NORTHWARD SHIFT OF
ONLY A FEW MILES WOULD BRING ACCUMULATING SNOWS INTO THE SOUTHERN
TIER COUNTIES. WILL DEFINITELY NEED TO MONITOR THIS OVER THE NEXT
FEW MODEL RUNS.

THE ECMWF...WHICH HAS BEEN THE MOST CONSISTENT OF THE DETERMINISTIC
MODELS WITH THIS SYSTEM...HAS NOW SWITCHED THINGS UP BY KEEPING THE
UPPER LEVEL SYSTEM FARTHER NORTH ON THURSDAY...DUE TO STRONGER
DOWNSTREAM BLOCKING. THIS WOULD KEEP A CHANCE OF LIGHT SNOW OVER THE
SOUTHEAST CWA. FOR NOW WILL STICK WITH A BLEND OF MODELS WITH
PERSISTENCE...WHICH KEEPS THE SOUTHEAST DRY AND SEE IF THIS WAS JUST
AN ANOMALY FROM THE 00 UTC MONDAY ECMWF RUN.

THIS CHANGE IN THE ECMWF ALSO AFFECTS THE LATTER PORTIONS OF THE
EXTENDED PERIOD. THE SLOWER SOLUTION RESULTS IN UPSTREAM RIDGING AND
THE PROGRESSIVE FLOW OFF THE PACIFIC IS SHUNTED NORTH...YIELDING A
MAINLY DRY FORECAST LATE IN THE WORK WEEK AND INTO THE WEEKEND. THIS
FINALLY BREAKS DOWN BY LATE SATURDAY AND A SYSTEM EMANATING FROM THE
PACIFIC MOVES INTO THE AREA SATURDAY NIGHT AND SUNDAY. THE GFS/GEM
BRING THE PROGRESSIVE FLOW INTO THE AREA EARLIER. THE SYSTEM
FORECAST TO MOVE INTO THE CWA ON THURSDAY FROM PREVIOUS RUNS IS
WEAKER...AND HAVE TONED DOWN POPS A BIT FROM PREVIOUS FORECAST. THE
NEXT SYSTEM ENTERS A GOOD 12-18 HOURS PRIOR TO THE ECMWF. EITHER
SOLUTION WOULD BRING ANOTHER ROUND OF MIXED PRECIPITATION WITH SNOW
NORTH...RAIN SOUTH...AND A MIX IN THE MIDDLE. TEMPERATURES DO
MODERATE LATER IN THE PERIOD...FROM HIGHS IN THE 20S AND 30S ON
TUESDAY AND WEDNESDAY...TO THE 30S AND 40S THURSDAY THROUGH SUNDAY.
WHICH WILL STILL BE BELOW NORMAL FOR MID APRIL.
