AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DULUTH MN
311 PM CDT THU MAY 6 2010

.DISCUSSION...
LOW PRESSURE FROM COLORADO WILL REACH THE OHIO VALLEY LATE FRIDAY.
A SECONDARY LOW...A REFLECTION OF A STRONG SHORT WAVE ALOFT...WILL
APPROACH FROM SOUTH DAKOTA AND BE ABSORBED BY THE OHIO VALLEY LOW
FRIDAY EVENING. THIS SHORT WAVE AND SECONDARY LOW WILL BRING DEEP
COLD AIR FROM WESTERN ONTARIO DOWN LAKE SUPERIOR TOWARD OUR AREA.
RAIN ASSOCIATED WITH THE SECONDARY LOW WILL SPREAD ACROSS OUR AREA
TONIGHT...AND MIX AT TIMES WITH SNOW...OFF AND ON...AS TEMPERATURES
FALL FRIDAY AFTERNOON. A MIX OR CHANGEOVER TO WET SNOW COULD
ACCUMULATE 2 TO 4 INCHES ACROSS THE BRAINERD LAKES AREA EAST
THROUGH THE DULUTH AREA AND UPPER SAINT CROIX VALLEY EASTWARD
THROUGH MUCH OF NORTHWEST WISCONSIN BY SATURDAY MORNING. THE SHORT
WAVE AND ITS ASSOCIATED SURFACE LOW WILL BOTH MOVE RAPIDLY
EAST...TAKING THE CHILLY AIR AND MIXED PRECIPITATION WITH THEM.
HIGH PRESSURE FRON THE NORTHERN PLAINS WILL BUILD OVER OUR AREA
SATURDAY NIGHT AND SUNDAY.

.EXTENDED...SUNDAY NIGHT THROUGH THURSDAY.
THE EXTENDED FORECAST PERIOD CONTINUES TO LOOK UNSETTLED...AT LEAST
MONDAY NIGHT THROUGH TUESDAY NIGHT WHEN MOST OF THE MODELS SHOW A
LOW PRESSURE SYSTEM LIFTING NEWD ACROSS THE UPPER MIDWEST...BRINGING
RAIN TO MUCH OF THE REGION. THERE ARE SOME DIFFERENCES BETWEEN THE
MODELS WITH THE GEM AND GFS BRINGING RAIN MAINLY TO THE SOUTHERN
HALF OF OUR CWA...WHILE THE DGEX KEEPS ALL THE RAIN TO THE SOUTH OF
OUR CWA...AND THE ECMWF TAKES THE PRECIP ALL THE WAY UP ACROSS OUR
NRN ZONES. HPC IS FOLLOWING THE ECMWF SOLUTION...SO FOR
CONSISTENCY...WE WILL ALSO. HOWEVER THIS EVENT WILL NEED TO BE
MONITORED FOR MODEL TRENDS...ESPECIALLY PRECIP FIELDS IN THE ECMWF.
BY WEDNESDAY NIGHT AND THURSDAY...MOST OF THE MEDIUM RANGE MODELS
SHOW DRY CONDITIONS...EXCEPT FOR AGAIN THE ECMWF WHICH SHOWS
SCATTERED PRECIP CONTINUING ACROSS THE NORTHLAND.

.AVIATION...05/06/18Z ISSUANCE...
AREAS OF CLOUDS WITH HIGH MVFR AND LOW VFR CIGS WILL CONTINUE TO
AFFECT THE NORTHLAND THROUGH TONIGHT...SCATTERING OUT FROM TIME TO
TIME ESPECIALLY AROUND LAKE SUPERIOR. CLOUD COVER WILL INCREASE
LATE TONIGHT AND FRIDAY MORNING AS LOW PRESSURE APPROACHES FROM
THE WEST. LIGHT RAIN WILL SPREAD ACROSS OUR SRN ZONES BY
MORNING...ALTHOUGH VSBYS SHOULD REMAIN MAINLY VFR.
