AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GLASGOW MT
906 AM MDT SAT JUL 23 2005

.SHORT TERM...FOR NORTHEAST MONTANA TODAY...
ONE BATCH OF SHOWERS EXITING OUR EASTERN ZONES THIS MORNING.  THESE
SHOWERS APPEAR TO BE JUST AHEAD OF A COLD FRONT AND ALONG AN AREA OF
SURFACE CONVERGENCE.  ANOTHER SMALL BATCH OF SHOWERS AND STORMS ARE
MOVING THROUGH SOUTHERN VALLEY AND NORTHERN GARFIELD COUNTIES...AND
THEY APPEAR TO BE ASSOCIATED WITH AN ELONGATED AREA OF VORTICITY
BEHIND THE FRONT.  IT APPEARS THAT THE SUPPORT FOR THESE SHOWERS
WILL LIFT UP INTO CANADA LATER THIS MORNING AND THAT THEY SHOULD
FALL APART WITHIN THE NEXT COUPLE OF HOURS.  THE WIND IS JUST
STARTING TO PICK UP ACROSS THE WESTERN HALF OF THE CWA...AND SHOULD
GET CRANKING PRETTY GOOD LATER THIS MORNING AS STRONGER MIXING
COMMENCES.  THE 12Z KGGW SOUNDING HAD 25-40KT WIND BETWEEN
850-700H.  ONCE THE STRONGER WEST/NORTHWEST WIND KICKS IN GOOD
DOWNSLOPING WILL CAUSE THE DEW POINTS TO DROP BACK INTO 40S ACROSS
OUR WESTERN ZONES...AND WITH HIGHS UP AROUND 90 DEGREES THE RELATIVE
HUMIDITY WILL LIKELY DROP BACK INTO THE TEENS THIS AFTERNOON.  DEW
POINTS STARTING OFF UP NEAR 70 DEGREES IN THE EAST...BUT WILL FALL
BACK ONCE THE WEST WIND KICKS IN LATER THIS MORNING.  WILL UPDATE
THE TREND IN THE DEW POINTS/RH SOME BASED ON THE 15Z OBS.   THE RED
FLAG WARNING AND LAKE WIND ADVISORY THAT ARE OUT LOOK FINE AND WILL
NOT MAKE ANY CHANGES. CB

.PREVIOUS DISCUSSION...FOR NORTHEAST MONTANA...TODAY THROUGH
MONDAY

SW FLOW ALOFT TURNS ZONAL TODAY AS A SHORTWAVE MOVING ACROSS
MONTANA FLATTEN THE FLOW.

TWO FRONTAL BOUNDARIES ARE MOVING EAST ACROSS MONTANA AT THIS TIME.
ONE IS A WARM FRONT THAT EXTENDS FROM WHITEWATER THROUGH JORDAN TO
BROADUS. THE OTHER IS A COLD FRONT THAT EXTENDS FROM WEST OF HAVRE
THROUGH GREAT FALLS TO DILLON. BOTH FRONT WILL MOVE EAST THROUGH THE
FORECAST AREA THIS MORNING AND SHOULD EXIT THE STATE BETWEEN 15 AND
18Z. THE NET EFFECT OF THESE FRONTS IS NORTHEAST MONTANA WILL BE
WARMER AND DRIER TODAY. DEW POINTS WILL DROP FROM THE 60S TO THE 40S
TODAY ESPECIALLY IN THE WESTERN ZONES. A TIGHT SURFACE GRADIENT AND
RAPID PRESSURE RISES TODAY WILL RESULT IN GUSTY WEST WINDS. WITH 850
AND 700 MB WINDS BETWEEN 30 AND 40 KNOTS...WINDS WILL STAY BELOW
HIGH WIND WARNING CRITERIA. THE WIND WILL EASILY MEET LAKE WIND
ADVISORY CRITERIA. IN THE WEST THE RH WILL FALL INTO THE TEENS TODAY
WHICH WILL BE LOW ENOUGH FOR RED FLAG WARNING IN FIRE WEATHER ZONES
119 AND 121. WITH GOOD MIXING...HIGHS WILL BE NEAR 90.  SOME SHOWERS
AND THUNDERSTORMS COULD LINGER THIS MORNING IN THE ERN ZONES UNTIL
THE FRONT PASSES. WILL MENTION A SLIGHT CHANCE THERE.

HIGH PRESSURE BUILDS INTO MONTANA TONIGHT BRINGING MOSTLY CLEAR
SKIES AND LIGHT WINDS.

A WEAK COLD FRONT DROPS SOUTH ACROSS THE FORECAST AREA SUNDAY
MORNING WHICH WILL BRING A COOLING TREND THROUGH MONDAY. WHILE A
HIGH PRESSURE RIDGING EAST ALONG THE CANADIAN BORDER FROM
ALBERTA...WEAK SHORTWAVES WILL AFFECT SOUTHERN MONTANA. LOOK FOR DRY
WEATHER FOR THE MOST PART IN NORTHEAST MONTANA FOR SUNDAY AND
MONDAY. THE SHORTWAVES TO THE SOUTH COULD BRING A THUNDERSTORMS AS
FAR NORTH AS THE SOUTHERN ZONES OF THE FORECAST AREA. MONDAYS
TEMPERATURES WILL BE WELL BELOW NORMAL. FORRESTER

.LONG TERM...MONDAY NIGHT THROUGH SATURDAY...

AN EXITING OF THE TROUGH FROM THE REGION WILL COOL TEMPERATURES A
BIT MONDAY NIGHT. NORTHWEST FLOW ALOFT WILL CONTINUE THROUGH
WEDNESDAY. A RIDGE WILL BUILD BEGINNING THURSDAY WHICH WILL RESULT
IN WARMING TEMPERATURES INTO THE WEEKEND. A TROUGH APPROACHING THE
WEST COAST WILL INCREASE THE THREAT OF THUNDERSTORMS OVER THE
WEEKEND. AT THIS POINT THE FORECAST STILL LOOKS DRY SO WILL LEAVE
POPS ALONE FOR NOW. SCT/RAE

&&

.AVIATION...A FRONT WILL MOVE ACROSS THE REGION EARLY THIS MORNING
WITH WINDS SWINGING FROM EAST TO WEST. THE WEST WINDS WILL INCREASE
AFTER SUNRISE TO 20-30KTS WITH GUSTS TO 40KT. OTHER THAN THE
POSSIBILITY OF A THUNDERSTORM NEAR GDV THIS MORNING EXPECT VFR
CONDITIONS THROUGH THE DAY. RAE

TEENS IN THE WESTERN ZONES TODAY. RH WILL BE SOMEWHAT HIGHER IN THE
EAST. WILL ISSUE RED FLAG WARNING FOR ZONES 119 AND 121 IN THE WEST
TODAY.  ZONE 122 IN THE SE WILL BE BORDERLINE RED FLAG. FIRE DANGER
IS LOW IN ZONE 120 IN THE NE WHERE THE MOST RAIN HAS FALLEN THIS
