AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
309 PM MDT TUE APR 17 2007

.DISCUSSION...
TONIGHT THROUGH THURSDAY...A DEEP UPPER TROUGH NEAR THE WEST COAST
WILL SWING INLAND TONIGHT AND THEN ROTATE NE INTO EASTERN MONTANA ON
THURSDAY. A WET PATTERN IS IN STORE FOR THE AREA WITH COOLING
TEMPERATURES. AS FOR THE WINTER STORM SITUATION...HAVE UPGRADED THE
WINTER STORM WATCHES TO HEAVY SNOW WARNINGS OVER THE WESTERN
MOUNTAINS. ALSO IT LOOKS AS IF THE FAR NW PLAINS WILL BECOME COLD
ENOUGH FOR SNOW BY LATE TONIGHT SO HAVE ADDED A SNOW ADVISORY FOR
THAT AREA AS WELL. DEPENDING ON HOW THINGS PLAY OUT MIGHT NEED
TO UPGRADE THE SNOW ADVISORY. AS THE UPPER TROUGH/LOW MOVES INTO
EASTERN MONTANA ON THURSDAY MOISTURE WILL BACK OVER THE EASTERN
PORTIONS OF THE FORECAST AREA. THE PLAINS COULD BE COLD ENOUGH BY
THAT TIME THAT PRECIPITATION WOULD BE IN THE FORM OF SNOW. MIGHT
NEED A SNOW ADVISORY FOR THURSDAY BUT AT THIS POINT WILL CONTINUE TO
MONITOR MODEL TRENDS. AS FOR THE THUNDERSTORM SITUATION...HAVE
DECIDED TO LEAVE IN THE THREAT OF THUNDERSTORMS OVER PORTIONS OF THE
SOUTH FOR THIS EVENING. INSTABILITY IS MARGINAL BUT CAN NOT RULE OUT
A STRIKE OR TWO. FOR WEDNESDAY THINK THE MAIN THREAT FOR
THUNDERSTORMS WILL BE EAST OF THE FORECAST AREA SO HAVE LEFT OUT
MENTION OF SAME EVEN THOUGH SOME GUIDANCE SUGGESTS THERE COULD BE
SOME THUNDERSTORMS OVER THE FAR EASTERN ZONES. BLANK

THURSDAY NIGHT THROUGH SUNDAY NIGHT...CLOSED LOW MOVING NORTH OUT OF
EASTERN MONTANA WILL BRING WRAP AROUND SHOWERS TO CENTRAL MONTANA
THURSDAY NIGHT. WILL SEE A BREAK IN PRECIPITATION FRIDAY AS THE AREA
IS IN BETWEEN SYSTEMS. THE NEXT SYSTEM ON SATURDAY IS LOOKING MORE
AND MORE LIKE ITS GOING TO MISS THE AREA TO THE SOUTH...THUS HAVE
LOWERED POPS FOR THIS PERIOD. SUNDAY LOOKS LIKE THE BEST CHANCE FOR
PRECIPITATION AS A SHORT WAVE MOVES ACROSS THE NORTHERN PART OF THE
U.S. TEMPERATURES DURING THIS PERIOD WILL BE NEAR NORMAL FOR THE
ENTIRE TIME FRAME. MEIER

MONDAY AND TUESDAY...A QUICK MOVING PACIFIC TROUGH OF LOW PRESSURE
IS EXPECTED TO PASS THROUGH MONDAY CAUSING SCATTERED SHOWERS FOR
MUCH OF THE REGION. A SHORT BREAK TUESDAY BEFORE A WEAK HIGH
PRESSURE BUILDS INTO WESTERN MONTANA A HEAD OF THE NEXT PACIFIC
SYSTEM MOVING INTO THE PACIFIC NORTHWEST. TEMPERATURES WILL BE NEAR
NORMAL THROUGH THE PERIOD. SAUCIER

&&

.AVIATION...
UPDATED 0015Z.
A DEEP UPPER LEVEL TROUGH ALONG THE PACIFIC COAST AT 00Z WILL KEEP A
MOIST AND UNSETTLED SOUTHWEST FLOW ALOFT OVER MONTANA TONIGHT.
SCATTERED SHOWERS AND MVFR CONDITIONS WILL DEVELOP OVER THE AREA
THIS EVENING...MAINLY SOUTH AND EAST OF KCTB. ISOLATED
THUNDERSTORMS WITH GUSTY WINDS ARE ALSO POSSIBLE DURING THIS TIME
SOUTH AND EAST OF A KHMM-KGTF-KHVR LINE. THE AIRMASS WILL GENERALLY
STABILIZE AFTER 02Z. THE UPPER LEVEL TROUGH MOVES INTO THE GREAT
BASIN BY WEDNESDAY MORNING...FOR AN INCREASINGLY MOIST SOUTHERLY
FLOW OVER THE FORECAST AREA. A SURFACE LOW PRESSURE AREA MOVES INTO
SOUTH CENTRAL MONTANA DURING THIS TIME FOR NORTHERLY UPSLOPE SURFACE
WINDS. WIDESPREAD PRECIPITATION WILL DEVELOP OVER WESTERN MONTANA
AND SPREAD INTO CENTRAL MONTANA...WITH MORE WIDESPREAD MVFR
CONDITIONS DEVELOPING AFTER 03Z. SNOW WILL BEGIN MIXING WITH THE
RAIN AFTER 06Z AS A COLDER AIRMASS BEGINS MOVING INTO THE AREA.
