AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN
712 AM CDT TUE APR 7 2015

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 405 AM CDT TUE APR 7 2015

PRECIPITATION HAS BEEN SLOWLY DIMINISHING THIS MORNING WITH THE LOSS
OF FORCING. WHAT RETURNS ARE PRESENT ON RADAR...ARE STRUGGLING TO
REACH THE GROUND DUE TO A PERSISTENT DRY NORTHEAST FLOW. DEW POINTS
HAVE FALLEN INTO THE 20S AND EVEN SOME TEENS ACROSS NORTHERN
TODD...MORRISON...AND MILLE LACS COUNTIES. AT 3 AM...THERE WAS A
BATCH OF STEADIER DRIZZLE ALONG AND JUST SOUTH OF I-94...BUT
TEMPERATURES ARE HOLDING STEADY IN THE MID 30S THERE DESPITE THE DRY
NORTHEAST FLOW. EVEN IF ADDITIONAL DRIZZLE DEVELOPS...THE SURFACE IS
TOO DRY TO ALLOW FOR MUCH...IF ANY ICE ACCUMULATION. THEREFORE...
THE FREEZING RAIN ADVISORY FOR THIS MORNING WILL BE CANCELLED.

CLOUDY SKIES WILL PERSIST THROUGH THE MORNING WITH ONLY A SLIGHT
CHANCE OF DRIZZLE OR LIGHT RAIN. LOW PRESSURE OVER KANSAS WILL TRACK
NORTHEAST INTO NORTHERN MISSOURI THIS AFTERNOON. MOISTURE
CONVERGENCE AND FORCING WITH THE SYSTEM WILL ALLOW FOR A CLUSTER OF
SHOWERS AND EMBEDDED THUNDERSTORMS TO DEVELOP THIS AFTERNOON ACROSS
IOWA AND SOUTH CENTRAL/SOUTHEAST MINNESOTA. THIS WEAK MCS WILL
PROPAGATE EAST QUICKLY ACROSS SRN WI DURING THE EVENING HOURS. BEST
WINDOW OF RAIN FOR SRN MN WILL BE AROUND MID AFTERNOON...BEFORE
THINGS DRY OUT IN THE EARLY EVENING. NOT REAL CONFIDENT ON MUCH
FALLING FURTHER TO THE NORTH DESPITE THE LIGHT QPF ON ALL THE
MODELS. PATCHY/AREAS OF DRIZZLE IS PROBABLY THE WORST CASE
SCENARIO...SO KEPT POPS LOW.

.LONG TERM...(WEDNESDAY THROUGH MONDAY)
ISSUED AT 405 AM CDT TUE APR 7 2015

THE LONG TERM CONCERNS REMAIN TIMING OF MOISTURE AND INSTABILITY
INFLUX AHEAD OF WESTERN CONUS TROUGH AND SURFACE CYCLOGENESIS.

EARLY IN THE PERIOD CONTINUES TO INDICATE A LULL IN OVERALL
PRECIPITATION FOR MOST OF WEDNESDAY. WE COULD SEE SOME DRIZZLE
BUT THE MAIN SURGE OF MOISTURE AND INSTABILITY RIDES INTO THE
AREAS WEDNESDAY NIGHT INTO THURSDAY. THIS SHOULD GENERATE
WIDESPREAD RAIN AND EVEN SOME THUNDER TO PORTIONS OF THE CWA. IT
DOES LOOK LIKE THE BEST SHOT OF THUNDER WILL BE FOUND ACROSS SOUTH
CENTRAL MN WEDNESDAY NIGHT INTO THURSDAY...AS THE SURFACE LOW
LIFTS OUT INTO THE CENTRAL PLAINS AND INTO IOWA BY THURSDAY
MORNING.

THE GFS CONTINUES TO BE STRONGEST/DEEPEST WITH THE SURFACE AND
OVERALL DEVELOPMENT OF THE UPPER TROUGH. ITS TREND OF DEVELOPING
A CLOSED LOW AND LIFTING IT OVER SOUTHERN MN AND INTO SOUTHERN
WISCONSIN THURSDAY NIGHT IS GENERALLY ACCEPTED PER THE MODEL
DIAGNOSTIC DISCUSSION. MODELS HAVE HAD A DIFFICULT TIME DISCERNING
THE AMOUNT OF NORTHERN STREAM ENERGY DROPS INTO THE NORTHERN
CONUS FROM CANADA. WILL FOLLOW MORE OF THE GFS FOR NOW...AND AS
THE MAIN TROUGH SWINGS ASHORE THIS MORNING...THE 12Z MODELS RUNS
SHOULD HAVE A BETTER HANDLE ON THE SYSTEM.

FOR SENSIBLE WEATHER...WILL CONTINUE THE CLOUDY AND WET FORECAST
THROUGH FRIDAY MORNING. BEST SHOT OF MORE SIGNIFICANT
PRECIPITATION WILL BE TO THE EAST WEDNESDAY NIGHT AND INTO
THURSDAY. SOME SHIFT POSSIBLE LATER THURSDAY AND THURSDAY NIGHT IF
THE GFS VERIFIES AND LIFTS THE UPPER LOW AND ATTENDANT F-GEN AND
DEFORMATION  ACROSS THE STATE. ALSO...TRACK OF THIS SYSTEM FAVORS
SOME BAND OF WET SNOW...AND THE GFS CONTINUES TO DEVELOP A SNOW
BAND FROM SOUTHWEST MN...TO THE TWIN CITIES INTO NORTHWEST
WISCONSIN BY 12Z FRIDAY. THE 00Z ECMWF WAS MOST PROGRESSIVE WITH
THE UPPER TROUGH AND LIFTED MOST OF THE PRECIPITATION THROUGH
EARLIER THURSDAY NIGHT. AT THE MOMENT...HAVE ANY REAL SNOW
ACCUMULATION LIMITED TO THE FAR NORTHEAST PORTION OF THE CWA
DURING THE PERIOD.

DRIER CONDITIONS AND MORE SUNSHINE ARE EXPECTED THROUGH SATURDAY.
THIS SHOULD PROMOTE WARMER THAN AVERAGE TEMPERATURES MOST AREAS.
THE NEXT TROUGH APPROACHES THE AREA FRO SUNDAY AND MONDAY. MODELS
CONTINUE TO DRIVE ANOTHER SURGE OF MOISTURE NORTH OVER THE AREA AS
ANOTHER STRONG SURFACE LOW TRACKS FROM THE CENTRAL PLAINS TOWARD
THE WESTERN GREAT LAKES.
