AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BILLINGS MT
928 PM MDT WED AUG 30 2006
.SHORT TERM...VALID FOR THU AND FRI...
VERY CHALLENGING FORECAST TONIGHT. COLD FRONT JUST NOW STARTING
TO GET BETTER DEFINED AS IT ROLLS OUT OF THE HIGHER TERRAIN.
FRONT BROKEN IN TWO PARTS...THE NORTHERN PART...WITH LESS
WIND...MOVED INTO BILLINGS EARLY THIS EVENING. THE WESTERN PART
HAS THE STRONGER PUNCH OF WINDS AND THIS STILL MOVING THROUGH THE
WESTERN PARTS OF SOUTH CENTRAL MONTANA. WINDS GUSTED TO 50 MPH AT
LIVINGSTON WHEN IT ZIPPED THROUGH AT 7 PM MDT. FRONTAL TIMING HAS
BEEN SLOWER THAN THE MODELS HAVE BEEN PROJECTING AS THIS LIKELY
DUE TO DEEPER AMPLIFICATION OF THE UPPER SYSTEM OVER IDAHO.
STRONGER WINDS WILL GET INTO BILLINGS BY MIDNIGHT AND PUSH
EASTWARD INTO THE EAST OVERNIGHT. SURFACE PRESSURE RISES ON THE
ORDER OF 2MB AN HOUR PUSHING ACROSS CENTRAL MONTANA. 850MB WINDS
OF 40KTS PUSHING ACROSS THE AREA TOO. SUBSIDENCE DOES GET
INVOLVED...BUT WINDS NOT LINKED UP TILL LATE AND AT THAT
POINT...WINDS ARE PROGGED TO DECREASE AT 850-700MB. HAVE HIT THE
WINDS A LITTLE HARDER AND LINGERED THE STRONGER WINDS LONGER
OVERNIGHT INTO THE MORNING...ESPECIALLY OUT EAST. CONTEMPLATED A
HIGH WIND WARNING FOR CENTRAL AND EASTERN ZONES BUT WILL HOLD OFF
FOR NOW AS REPORTS COMING IN WITH THE FRONT HAVE NOT BEEN AT
CRITERIA AS OF YET. ALL DAY SHIFT POINTED OUT EARLIER...NOT ALL
INGREDIENTS THERE FOR HIGH WIND...AND TIME OF DAY NOT IDEAL FOR
STRONG WIND EVENTS THIS TIME OF YEAR. WINDS HIT PRETTY HARD IN
THE GRIDS AND WILL KEEP THAT THEME WITH GUSTS NEAR 50 MPH. POPS
LOOK IN OKAY SHAPE AS AN ISOLATED THUNDERSTORM DEVELOPED NORTH OF
BILLINGS THIS EVENING. LARGE SWATH OF PRECIPITATION OVER CENTRAL
MONTANA WAS SHIFTING NORTH AND EAST...WHICH WOULD KEEP IT MOSTLY
OUT OF THE AREA. DID RAISE POPS OVER THE WEST AND NORTH A BIT TO
ACCOUNT FOR THIS. RED FLAG WILL REMAIN IN PLACE WITH STRONG WINDS
OVERNIGHT. HUMPHREY
.LONG TERM...VALID FOR SAT...SUN...MON...TUE...WED...
UPPER LEVEL RIDGE BECOMING THE SOLE WEATHER FEATURE OF THE
EXTENDED FORECAST AS MODELS GAIN CONFIDENCE IN LIMITING THE
INFLUENCE OF AN UPPER LEVEL LOW PRESSURE SYSTEM OVER THE FORECAST
AREA. ON SATURDAY THE UPPER LEVEL RIDGE BUILDS OVER THE AREA WITH
THE UPPER LEVEL LOW DEVELOPING OVER EASTERN NORTH DAKOTA.
NORTHERLY FLOW ALOFT OVER THE EASTERN ZONES MAY SLOW DOWN WARMING
BUT PATTERN IS GENERALLY SUPPORTIVE OF TEMPERATURES ABOVE NORMAL
AND REACHING THE MID 80S. FOR SUNDAY AND MONDAY THE NORTHERLY FLOW
WEAKENS AND THE UPPER LEVEL RIDGE BROADENS OUT A BIT KEEPING A DRY
AIRMASS IN PLACE. THE RIDGE BEGINS TO LOOK LIKE AN OMEGA BLOCK
PATTERN SO IT MAY PERSIST LONGER THAN CURRENT PROGS SUGGEST.
BIGGEST FACTOR THAT WILL KEEP TEMPERATURES FROM REACHING THE 90S
IS THAT SURFACE HIGH PRESSURE DOMINATES THE DAKOTAS AND THIS WILL
KEEP AND EASTERLY SURFACE FLOW AND SHOULD LIMIT FULL MIXING MOST
DAYS. THE RIDGE TRIES TO BREAK DOWN BY TUESDAY WITH SOME MONSOONAL
MOISTURE TRYING TO REACH THE AREA. STILL SHOULD BE A SLOW
BREAKDOWN TO THE RIDGE WITH THE NORTHERLY BRANCH OF THE JET STREAM
STAYING WELL TO THE NORTH OF THE AREA. THIS WILL KEEP TEMPERATURES
ABOVE NORMAL EARLY NEXT WEEK WITH FAIRLY QUIET WEATHER. BORSUM
&&
.AVIATION...
SKIES OVERNIGHT WILL BE PARTLY CLOUDY WITH AN ISOLATED SHOWER OR
THUNDERSTORM. A WILDFIRE SOUTH OF BIG TIMBER WILL PROVIDE AREAS
OF SMOKE FROM KBIL TO KLVM DURING THE NIGHT REDUCING VISIBILITIES
AT TIMES. OTHERWISE...VFR CONDITIONS WILL PREVAIL. A COLD FRONT
WILL CONTINUE TO SWEEP ACROSS THE AREA THIS EVENING AND OVERNIGHT
BRINGING STRONG GUSTY SURFACE WINDS OVER 30 KTS AT TIMES THROUGH
12Z. HOOLEY
