AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GLASGOW MT
347 AM MDT WED AUG 8 2007

.SHORT TERM...FOR NORTHEAST MONTANA...TODAY THROUGH FRIDAY...
A WEAK COLD FRONT LINGERS OVER EASTERN MONTANA AT 09Z NEAR SCOBEY
...CIRCLE AND MILES CITY. SCATTERED THUNDERSTORMS ARE CURRENTLY
MOVING NORTHEAST INTO THE FORECAST AREA AHEAD OF THE FRONT. AN
UPPER LEVEL TROUGH IS MOVING EAST THROUGH CENTRAL MONTANA AND WILL
MOVE THROUGH EASTERN MONTANA THIS MORNING. WILL KEEP A MENTION OF
ISOLATED TO SCATTERED THUNDERSTORMS THIS MORNING IN THE EAST UNTIL
THE FRONT EXITS THE FORECAST AREA.

VERY DRY AND SOMEWHAT COOLER AIR IS EXPECTED OVER NORTHEAST
MONTANA. WEST WINDS SHOULD ADVECT SOME MID TO UPPER 30S DEW POINTS
FROM CENTRAL MONTANA INTO THE FORECAST AREA WHICH WILL CREATE RH
IN THE TEENS THIS AFTERNOON. WITH GOOD MIXING...SHOULD SEE 15 TO
20 MPH WINDS ESPECIALLY IN THE WEST THIS AFTERNOON WILL CREATE
FIRE WEATHER CONCERNS. SEE FIRE WEATHER DISCUSSION BELOW FOR DETAILS.

AFTER THE UPPER TROUGH PASSES THIS MORNING...LOOK WEST SOUTHWEST
FLOW ALOFT BETWEEN WEST COAST UPPER TROUGH AND RIDGE TO THE EAST
FOR THE REST OF THE SHORT TERM PERIOD. A WEAK COLD FRONT DROPS
SOUTH TONIGHT WHICH WILL MAKE THE WIND MORE NORTHERLY FOR THURSDAY
AND TEMPERATURES A FEW DEGREES COOLER IN SOME PLACES.

A WEAK SHORTWAVE IN THE SOUTHWEST FLOW ALOFT AFFECTS NORTHEAST
MONTANA THURSDAY NIGHT. IT MAY BE STRONG ENOUGH TO SQUEEZE SOME
MOISTURE OUT OF THE ATMOSPHERE. WILL MENTION A SLIGHT CHANCE OF
THUNDERSTORMS LATE THURSDAY NIGHT.

ON FRIDAY...A COLD FRONT IS EXPECTED TO PASS THROUGH THE FORECAST
AREA LATE FRIDAY AFTERNOON OR FRIDAY EVENING. WITH UNSTABLE
AIRMASS...MAY SEE SOME THUNDERSTORMS DEVELOP IN THE AFTERNOON.
WILL MENTION A SLIGHT CHANCE FOR NOW. FORRESTER

.LONG TERM...FRIDAY NIGHT THROUGH WEDNESDAY...
NOT A LOT OF CHANGE IN THE WEATHER EXPECTED FROM WHAT WE HAVE BEEN
HAVING. A VERY LARGE AND SPRAWLING HIGH PRESSURE ALOFT COVERS A
LARGE PART OF THE U.S. WHICH IS TYPICAL OF MID-SUMMER. THE
ORIENTATION OF THE HIGH...WITH THE CENTER OF IT FAR TO OUR SE...OVER
ALABAMA...KEEPS NE MT IN A WEAK TO MODERATE SW FLOW ALOFT FRI NIGHT.
THERE IS A TROUGH OFF THE PACIFIC NW COAST. A SHORTWAVE FROM THIS
TROUGH MOVES NE INTO AB AND SK FRI NIGHT...BRUSHING OUR AREA. THAT
IS THE BEST CHANCE OF TSTORM ACTIVITY FOR NE MT DURING THE
PERIOD...AND IT IS NOT THAT GREAT. AND SIMILAR TO PAST FEW
WEEKS...IT DOES DRAG A COLD FRONT ACROSS THE AREA FOR A DAY OF
COOLER WEATHER SAT.

FOLLOWING THIS SHORTWAVE...A THE TROUGH RE-FORMS FARTHER WEST AND
THE UPPER HIGH RETROGRADES WEST WITH THE CENTER MOVING TO CO. 500
MB HEIGHTS CLIMB TO THE UPPER 580S DM AND THICKNESSES TO AROUND
580 DM. THIS IS SIMILAR TO WHAT WE HAVE BEEN HAVING WITH
WIDESPREAD 90S LATELY. THE PATTERN THIS SUMMER HAS BEEN TO RUN ON
THE HOT SIDE OF GUIDANCE AND OFTEN HOTTER THAN EXPECTED...SO WILL
RAISE HIGHS A FEW DEGREES MON/TUE. THE ORIENTATION AND STRENGTH
OF THE UPPER HIGH AND WITH MEAN RH 20-30 PCT...THERE WILL BE VERY
LITTLE TSTORM ACTIVITY AND SO HAVE LOWERED POPS. SIMONSEN

&&

.AVIATION...
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS LINGERING IN OUR SE
QUARTER OF THE FORECAST AREA EARLY THIS MORNING WILL HAVE ONLY
MINOR IMPACT ON CEILING AND VISIBILITY. OTHERWISE...VFR UNDER
MOSTLY CLEAR SKIES. SIMONSEN

&&

.FIRE WEATHER...
A RED FLAG WARNING HAS BEEN ISSUED FOR FIRE WEATHER ZONES 119 AND
121 FOR THIS AFTERNOON INTO EARLY EVENING AS CONDITIONS WILL MEET
RED FLAG WARNING CRITERIA. MINIMUM RELATIVE HUMIDITY VALUES WILL
REACH THE TEENS WITH A WEST TO NORTHWEST WIND OF 15 TO 20 MPH
GUSTING TO NEAR 30 MPH AT TIMES. WIND WILL GRADUALLY DIMINISH
AFTER 6 PM AND TEMPERATURES WILL ALSO BEGIN TO COOL. THURSDAY
AFTERNOON WILL AGAIN BE WARM AND DRY BUT WIND IS EXPECTED TO BE 5
TO 10 MPH LESS...GENERALLY IN THE 10 TO 15 MPH RANGE.
