AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE DULUTH MN
1244 AM CDT SUN APR 3 2016

.UPDATE...
ISSUED AT 1242 AM CDT SUN APR 3 2016

UPDATED 06Z AVIATION DISCUSSION BELOW...

&&

.SHORT TERM...(THIS EVENING THROUGH SUNDAY)
ISSUED AT 327 PM CDT SAT APR 2 2016

THE COLD AND GUSTY NW FLOW OVER THE NORTHLAND HAS BEEN DRIVING
LINGERING BKN/OVC CUMULUS AND SNOW SHOWERS. HOWEVER...DRIER AIR
AND SURFACE HIGH PRESSURE IS BUILDING INTO THE REGION, RESULTING A
GRADUAL CLEARING TREND FROM THE WEST. THE WINDS SHOULD DROP OFF
AFTER SUNSET...ACCELERATING THE CLEARING TREND AND PERHAPS GIVING
PEOPLE A CHANCE TO VIEW A POSSIBLE AURORA DUE TO A GEOMAGNETIC
STORM IN PROGRESS AS OF THE TIME OF WRITING THIS DISCUSSION. THE
CLEAR SKIES AND LIGHT WIND SPEEDS THIS EVENING SHOULD ALLOW RAPID
RADIATIONAL COOLING...SO LEANED ON THE COLDER MODEL
GUIDANCE...SUCH AS THE GFS.

HOWEVER...HIGHER LEVEL CLOUD COVER WILL BE MOVING IN FROM THE
WEST THIS EVENING IN ADVANCE OF A CLIPPER SYSTEM IN CANADA. THE
CLIPPER WILL DIVE OUT OF SASKATCHEWAN INTO NORTH DAKOTA LATE THIS
EVENING...THEN PASS THROUGH SE NORTH DAKOTA AND SOUTHERN MINNESOTA
EARLY SUNDAY. A MID LEVEL FRONTOGENETICAL BAND IS EXPECTED TO
DEVELOP SNOW ACROSS NORTHERN MINNESOTA...WESTERN LAKE
SUPERIOR...AND NEARBY AREAS OF NW WISCONSIN EARLY SUNDAY. THE SNOW
SHOULD BEGIN DURING THE WEE HOURS OF SUNDAY MORNING...REACH MAX
INTENSITY DURING THE MORNING HOURS AFTER SUNRISE...AND GRADUALLY
TAPER OFF DURING THE AFTERNOON. THERE IS STILL SOME UNCERTAINTY AS
TO WHERE EXACTLY THE BAND WILL SET UP...AND HOW MUCH PCPN WILL
FALL. HOWEVER...THE 12Z MODEL TREND WAS TO SHIFT THE BAND A LITTLE
FARTHER NORTH THAN THE 00Z RUNS. FOR THE MOST PART...LIGHT
SNOWFALL IS EXPECTED FOR AREAS NEAR AND NORTH OF HIGHWAY 2...ABOUT
1 TO 3 INCHES. ALTHOUGH...EASTERLY FLOW OVER LAKE SUPERIOR WILL
PROVIDE MOISTURE ENHANCEMENT TO RESULT IN GREATER SNOWFALL TOTALS
ALONG AND NEAR THE NORTH SHORE OF THE MINNESOTA ARROWHEAD. ABOUT 2
TO 4 INCHES ARE FORECAST FOR THE HIGHWAY 61 CORRIDOR AND HIGHER
TERRAIN ALONG THE NORTH SHORE. CONCERNED ABOUT THE AGGRESSIVE
CANADIAN REGIONAL MODEL...WHICH DEPICTS MUCH GREATER AND FOCUSED
PCPN THAN OTHER MODELS. MAY NEED TO REFINE THE SNOWFALL TOTALS AS
THE RAP AND HRRR COME INTO PLAY AND OFFER A MEANS TO BETTER
ESTIMATE THE TIMING AND LOCATION OF THE BAND.

OTHERWISE...BACKING WINDS WILL BRING COLDER AIR INTO THE REGION
SUNDAY. THE CLOUD COVER WILL LIMIT DAYTIME HEATING...BUT PARTS OF
THE FAR SOUTHERN FORECAST AREA COULD GET A PERIOD OF PARTLY SUNNY
SKIES DURING THE MIDDLE OF THE DAY AND BE ABLE TO WARM UP MUCH
MORE SO THAN THE MAJORITY OF THE FORECAST AREA. A SHORTWAVE WILL
LIKELY CUT ACROSS NORTHERN MINNESOTA LATE IN THE
AFTERNOON...PROVIDING SYNOPTIC LIFT TO RESULT IN HIGHER CHANCES OF
LIGHT SNOW ACROSS NORTHERN MINNESOTA DURING THE LATE AFTERNOON AND
EARLY EVENING.

.LONG TERM...(SUNDAY NIGHT THROUGH SATURDAY)
ISSUED AT 327 PM CDT SAT APR 2 2016

NORTHWEST FLOW WILL CONTINUE INTO MONDAY NIGHT...THEN A STRONGER
SHORTWAVE WILL MOVE INTO THE REGION TUESDAY/TUESDAY NIGHT.

THE NAM SHOWS LOW LEVEL CONVERGENCE OVER THE ARROWHEAD AREA
SUNDAY EVENING WITH COLD LOW LEVEL TEMPERATURES. 850MB
TEMPERATURES WILL RANGE FROM -10C OVER OUR SOUTHWEST AREA TO -18C
NORTHEAST AT 12Z MONDAY. WE HAVE INCREASED POPS AROUND LAKE
SUPERIOR SUNDAY NIGHT INTO MONDAY. THE MODELS DO SHOW DIFFERENCES
IN THE LOW LEVEL FLOW...BUT ALL SHOW A CHANCE FOR LAKE EFFECT. THE
NAM SUPPORTS MORE SNOW ALONG THE NORTH SHORE AND TWIN PORTS
COMPARED TO THE GFS/ECMWF. SOME ACCUMULATION LOOKS LIKELY...AND WE
1 TO 3 INCHES FROM THE NORTH SHORE TO THE TWIN PORTS AND ALONG THE
SOUTH SHORE SUNDAY NIGHT INTO MONDAY. SOME ADJUSTMENT WILL LIKELY
OCCUR AS BETTER AGREEMENT DEVELOPS ON THE LOW LEVEL FLOW. HIGH
PRESSURE WILL NOSE SOUTH MONDAY AND SHOULD KEEP THE REST OF THE
NORTHLAND DRY.

A SHORTWAVE AND SURFACE LOW PRESSURE SYSTEM WILL IMPACT THE
NORTHLAND TUESDAY INTO WEDNESDAY WITH A SECOND WEAKER QUICK MOVING
SYSTEM MOVING IN ON ITS HEELS FOR WEDNESDAY NIGHT/THURSDAY. THERE
REMAINS DIFFERENCES IN THE TRACK OF THESE SYSTEMS...BUT THE RESULT
WILL BE THE SAME ON THE FORECAST WITH A CHANCE FOR PRECIPITATION.
WE TRENDED A BIT COLDER TUESDAY/TUESDAY NIGHT AND HAVE MORE OF A
MIX TUESDAY AND SWITCH OVER TO A MIX OR ALL SNOW SOONER TUESDAY
NIGHT. SOME SNOW ACCUMULATION LOOKS LIKELY...MAINLY LIGHT AMOUNTS.

BOTH THE GFS AND ECMWF BUILD IN HIGH PRESSURE INTO THE REGION
LATE IN THE WEEK.

HIGHS MONDAY WILL BE FROM 30 TO 40 FOR MOST AREAS WITH MID
THIRTIES TO LOWER FORTIES TUESDAY/WEDNESDAY. TEMPERATURES WILL
DROP BACK TO 30 TO 40 THURSDAY AS COLDER AIR MOVES IN BEHIND THE
DEPARTING LOW. TEMPERATURES WILL THEN WARM TO OR A FEW DEGREES
ABOVE NORMAL LATE IN THE PERIOD.

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z SUNDAY NIGHT)
ISSUED AT 1240 AM CDT SUN APR 3 2016

ANOTHER FAST MOVING CLIPPER DEVELOPING OVER NORTHERN MINNESOTA
AND BACK NORTHWEST INTO SOUTHERN MANITOBA AS OF 05Z. A BAND OF
SNOW WITH MAINLY MVFR CEILINGS AND VISIBILITIES TO MOVE IN AFTER
08Z TONIGHT. KINL...KHIB AND KDLH TO BE MOST STRONGLY AFFECTED
WITH AT LEAST A FEW HOURS OF IFR CEILINGS AND VISIBILITIES IN
SNOW. HAVE TEMPO GROUPS FOR THIS FOR NOW AS TIMING IS UNCERTAIN AT
THIS TIME. ONCE THE SNOW COMES TO AN END FOR EACH SITE...MVFR
CEILINGS EXPECTED TO LINGER FOR SEVERAL MORE HOURS. KBRD AND KHYR
WILL ALMOST MISS OUT ON THIS WAVE...WITH THE BETTER SATURATION AND
LIFT NORTH OF BOTH LOCATIONS. KBRD TO REMAIN VFR THROUGH THROUGH
AT LEAST 18Z...WHEN THEY MAY GET SOME MVFR CEILINGS TO AFFECT THE
AREA...THOUGH CONFIDENCE IS LOW ON THIS AND HAVE LEFT THESE OUT
FOR NOW. KHYR IS VERY CLOSE TO THE EDGE OF THE SNOW BAND AND HAVE
PUT IN A SHORT PERIOD OF MVFR CEILINGS AND VISIBILITIES WHEN IT IS
CLOSEST...WITH LINGERING MVFR CEILINGS AS WELL. A SURGE OF COLD
AIR WILL PUSH INTO THE AREA AND CAUSE CEILINGS TO LOWER INTO IFR
AFTER 00Z.
