850 PM MDT MON SEP 5 2011

.SHORT TERM...FOR NORTHEAST MONTANA...TONIGHT THROUGH WEDNESDAY...

NO UPDATE ANTICIPATED TONIGHT.

PREVIOUS SHORT TERM DISCUSSION...
SHORT TERM FORECAST IS ON TRACK AND NOTHING HAS CHANGED SINCE
LAST NIGHT. ONE ISSUE THAT NEEDS TO BE LOOKED AT OVER NIGHT ARE
THE THE FIRE WEATHER CONCERNS OVER THE NEXT FEW AFTERNOONS. WE
RELATIVE HUMIDITIES BETWEEN 10 AND 15 PERCENT ACROSS MUCH OVER THE
REGION. SUSTAINED WIND SPEEDS REMAINED BELOW 10 MPH BUT WIND GUST
OFTEN REACHED THE UPPER TEENS. TOMORROW LOOKS MUCH LIKE TODAY AND
WE COULD EVEN SEE A FEW SINGLE DIGIT RELATIVE HUMIDITY READINGS.
EVEN WITH WIND SPEEDS UNDER 10 MPH GRASSLAND FIRES CAN STILL
SPREAD ESPECIALLY UNDER THESE CONDITIONS. WILL LET THE EVENING
SHIFT TAKE A LOOK AT TOMORROW. RSMITH

.LONG TERM...WEDNESDAY NIGHT THROUGH MONDAY...
LITTLE CHANGE IN THE MODELS TODAY. UPPER RIDGE DEVELOPS INTO A
CLOSED HIGH OVER THE NORTHERN PLAINS BY THURSDAY. THIS WILL KEEP
WARM AND DRY WEATHER OVER THE REGION BUT WITH LITTLE WIND
EXPECTED. TOWARD THE WEEKEND MODELS BRING THE FIRST ARCTIC WAVE OF
THE SEASON SOUTH ACROSS CENTRAL CANADA. THIS WAVE DROPS A BACK
DOOR COLD FRONT INTO NORTHERN MONTANA...WITH GFS A LITTLE COLDER
THAN THE ECMWF. EXPECTED COLDER WEATHER AT THE END OF THE FORECAST
PERIOD BUT QUESTION IS HOW MUCH COOLER. EBERT

PREVIOUS LONG TERM DISCUSSION...AN UPPER RIDGE WILL COVER MOST OF
THE WESTERN US THROUGH THE PERIOD. THIS WILL BRING WARM AND DRY
WEATHER WITH LIGHT WINDS TO THE FORECAST AREA. THE RIDGE WILL BE
AT ITS STRONGEST LATE THIS WEEK WHEN A CLOSED UPPER LEVEL HIGH
WILL BE CENTERED OVER NORTH DAKOTA.

THE ONLY QUESTION MARK IN THE RIDGE'S DOMINANCE INTO NEXT WEEK
WILL BE WHETHER OR NOT A SHORTWAVE TROUGH MOVING ACROSS THE
CANADIAN PRAIRIES THIS WEEKEND WILL BE ABLE TO DRAG A DRY BACKDOOR
COLD FRONT INTO NORTHEAST MONTANA. MODELS HAVE DIFFERED IN THEIR
DEPICTION OF THIS SYSTEM WITH THE CURRENT GFS HAVING THE FRONT AND
THE ECMWF NOT HAVING IT. THE MODELS WERE THE OTHER WAY AROUND WITH
THEIR PROGS IN LAST NIGHT'S RUNS. WILL HOLD OFF ON FORECASTING
THIS FRONT FOR NOW AND MAINTAIN THE ABOVE NORMAL TEMPERATURES INTO
NEXT WEEK. FORRESTER

.AVIATION...
VFR. WINDS WILL REMAIN LIGHT THROUGH THE MORNING HOURS. THEN LOOK
FOR SOME WIND GUSTS IN THE AFTERNOON.         PROTON
