AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DULUTH MN
249 PM CDT TUE JUL 29 2014

.SHORT TERM...(THIS EVENING THROUGH WEDNESDAY)
ISSUED AT 248 PM CDT TUE JUL 29 2014

SHOWERS AND STORMS CONTINUED TO DEVELOP AND MOVE THROUGH PORTIONS OF
NORTHEAST MINNESOTA AND NORTHERN WISCONSIN THIS AFTERNOON. AN
ISOLATED SEVERE THREAT OVER NORTHWEST WISCONSIN AND FAR EASTERN
MINNESOTA WILL CONTINUE INTO EARLY EVENING AS MLCAPE VALUES HAVE
RISEN TO AROUND 500J/KG OVER OUR EASTERN MINNESOTA ZONES AND ACROSS
NORTHERN WISCONSIN. 30-40KT OF 0-6KM SHEAR WAS ALSO OCCURRING.

THE UPPER LOW OVER SOUTHERN HUDSON BAY WILL ONLY MOVE SLIGHTLY SOUTH
OVER THE NEXT 30 HOURS. THE SHOWERS/STORMS THIS AFTERNOON WILL
DISSIPATE AND END LATER THIS EVENING WITH LOSS OF HEATING. CLOUDS
WILL DIMINISH AS WELL TONIGHT AND WINDS WILL BECOME LIGHT IN MANY
LOCATIONS. WE ADDED SOME PATCHY FOG TO PORTIONS OF THE NORTHLAND
LATE TONIGHT. LOWS TONIGHT WILL RANGE FROM THE UPPER FORTIES TO
LOWER FIFTIES.

NORTHERLY FLOW ALOFT WILL CONTINUE WEDNESDAY AND 500MB TEMPS ARE
FORECAST TO RISE A BIT. WE INCREASED POPS WEDNESDAY AFTERNOON AND
HAVE A MENTION OF A SHOWER/STORM EAST OF A LINE FROM INTERNATIONAL
FALLS TO PINE CITY WEDNESDAY AFTERNOON. THE BEST CHANCE WILL BE OVER
OUR FAR EASTERN ZONES CLOSER TO THE COLDER TEMPS ALOFT. HIGHS WILL
REACH THE MID TO UPPER SEVENTIES.

.LONG TERM...(WEDNESDAY NIGHT THROUGH TUESDAY)
ISSUED AT 248 PM CDT TUE JUL 29 2014

LONG RANGE MODELS ARE IN GOOD AGREEMENT THAT THE CUT OFF LOW OVER
EASTERN ONTARIO/JAMES BAY...REMAINS NEARLY STATIONARY THROUGH AT
LEAST THURSDAY. THE PERSISTENT CYCLONIC FLOW AND COOL TEMPS ALOFT
WILL CREATE ENOUGH INSTABILITY FOR AFTERNOON SHOWERS/ISOLD TSTM
AGAIN THURSDAY. LONG RANGE MODELS SUGGEST THE LOW FINALLY BEGINS TO
FILL AND VERY SLOWLY PUSH EAST FRIDAY...WITH A BRIEF PERIOD OF
RIDGING STAY/SAT NIGHT. HAVE LOWERED OVERNIGHT TEMPS THURSDAY NIGHT
AND AGAIN FRIDAY NIGHT AS DRIER DEW POINTS/OVERNIGHT CLEARING/LIGHT
WINDS ALLOW FOR RADIATIONAL COOLING.

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z WEDNESDAY AFTERNOON)
ISSUED AT 1230 PM CDT TUE JUL 29 2014

VFR CEILINGS WILL PREVAIL THROUGH THE TAF PERIOD. THE UNSTABLE
NORTHWEST FLOW WILL TRIGGER SCT SHOWERS AND A FEW THUNDERSTORMS
THROUGH THE EVENING. THE MAIN THREAT FOR THE SHOWERS AND STORMS
WILL BE ALONG AND EAST OF A LINE FROM KCDD...TO KHIB...KDLH..AND
SOUTH ALONG THE INTERSTATE 35 CORRIDOR. A FEW STORMS WILL HAVE THE
POTENTIAL TO BECOME STRONG THIS EVENING...MAINLY OVER NORTHERN
WISCONSIN. DUE TO THE UNCERTAINTY IN COVERAGE AND TIMING...HAVE
CONTINUED TO HANDLE WITH VCSH AND WILL NEED TO AMEND AS ANY TSTMS
DEVELOP.
