AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
325 AM EDT THU SEP 3 2015

.SHORT TERM...(THIS EVENING THROUGH THURSDAY)
ISSUED AT 403 PM EDT WED SEP 2 2015

UPPER AIR PATTERN CONSISTS OF A 500 MB TROUGH IN THE WEST...STRONG
500 MB RIDGE ACROSS THE PLAINS AND TROUGHING ACROSS THE EASTERN U.S.
THERE IS ALSO A SHORTWAVE ACROSS NEBRASKA. THE NAM SHOWS THE
SHORTWAVE OVER NEBRASKA AND ONE EJECTING OUT OF THE WEST TROUGH
HEADING OUR WAY AND AFFECTING THE AREA ON THU.

NAM KEEPS SOME WEAK 850-500 MB Q-VECTOR CONVERGENCE OVER THE AREA
THROUGH 00Z FRI WITH DEEPER MOISTURE ARRIVING THU AFTERNOON. VERY
LITTLE MOISTURE TO WORK WITH BEFORE THEN...SO EXPECT SOME CLOUDS
UNTIL THEN. DO HAVE POPS IN FOR LATER THU AFTERNOON ACROSS THE WEST
AS THE MOISTURE ARRIVES THEN AND THE SHORTWAVES NEAR. GOING
TEMPERATURES LOOKED GOOD AND MADE VERY FEW ADJUSTMENTS TO THE GOING
FORECAST. LOOKS LIKE THE BETTER POPS AND MOISTURE REMAIN OFF TO THE
SOUTHWEST OF THE AREA FOR THIS FORECAST PERIOD.

.LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 318 PM EDT WED SEP 2 2015

SPENT MOST TIME HELPING WITH SHORT TERM WARNING OPERATIONS...SO
RELIED HEAVILY ON PREVIOUS FORECAST AND CONSENSUS FOR THE LONG TERM
FORECAST.

OVERALL...EXPECT A SOME LOW END SHOWER AND THUNDERSTORM CHANCES IN
THE REGION FRI AND SAT AS THE UPPER RIDGE SITS OVER THE AREA WITH
SHORTWAVES PUSHING THROUGH THE RIDGE. A LOW PRESSURE SYSTEM WILL
MOVE FROM THE INTER-MOUNTAIN WEST LATE SAT TO HUDSON BAY BY
TUE...BRINGING INCREASED SHOWER AND THUNDERSTORM CHANCES SUN THROUGH
MON AS A COLD FRONT MOVES ACROSS. THE PROLONGED HEAT WILL GIVE WAY
TO COOLER TEMPS EARLY NEXT WEEK WHEN HIGH TEMPS WILL DROP DOWN
CLOSER TO NORMAL IN THE 60S AND 70S. ANOTHER SYSTEM MAY MOVE THROUGH
NEXT WED...POSSIBLY BRINGING PRECIP TO MUCH OF THE AREA...BUT
PREDICTABILITY IS LOW WITH THIS SYSTEM.

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z THURSDAY NIGHT)
ISSUED AT 324 AM EDT THU SEP 3 2015

LIFR/VLIFR CONDITIONS IN FOG ARE EXPECTED AT KIWD/KCMX/KSAW
OVERNIGHT DUE TO WET GROUND FROM RECENT RAIN...LIGHT WINDS AND
CLOUDS THINNING OUT. FOG/STRATUS WILL CLEAR OUT WITHIN A FEW HRS

BEYOND THIS FCST PERIOD.

.MARINE...(FOR THE 4 PM LAKE SUPERIOR FORECAST ISSUANCE)
