.SHORT TERM...FOR NORTHEAST MONTANA...TODAY THROUGH WEDNESDAY...
SYNOPTIC SET UP... A RIDGE RUNS UP THE GREAT PLAINS INTO NORTHERN
MANITOBA WHILE ANOTHER RUNS UP THE NORTH AMERICAN COAST INTO
BRITISH COLUMBIA. WEDGED BETWEEN THESE TWO RIDGES IS A TROUGH SPINE
OF THE ROCKY MOUNTAINS ALONG THE FRONT RANGE. ANOTHER LARGE
TROUGH LIES IN GULF OF ALASKA AND DIVES SOUTH INTO THE NORTHEAST
PACIFIC.

TODAY... THE TROUGH OVER THE FRONT RANGE WILL QUICKLY TRANSFER
EAST BUT COOL AIR EMBEDDED IN THE TROUGH WILL TAKE A BIT LONGER TO
ERADICATE NEAR THE SURFACE. CONSEQUENTLY TEMPERATURES WILL BE
LOWER TODAY THAN YESTERDAY AND TOP OUT AROUND NORMAL DURING THE
AFTERNOON.

AS THE TROUGH KICKS EAST A DRY WEST DOWNSLOPE WIND WILL BEGIN TO
FILL IN BEHIND IT THIS AFTERNOON. PETROLEUM AND GARFIELD COUNTY
ALONG WITH THE REMAINDER OF THE MISSOURI BREAKS UP THROUGH THE
WESTERN SHORES OF THE FORT PECK LAKE WILL SEE LOW RELATIVE
HUMIDITIES AND JUST ENOUGH WIND TO WARRANT A RED FLAG WARNING FOR
THESE NARROW AREAS.

TONIGHT THROUGH WEDNESDAY... UPPER LEVEL RIDGE WILL BEGIN TO FULLY
IMPACT THE REGION AND SHOULD BRING CLEAR TO PARTLY CLOUDY SKIES
ALONG WITH A WARMING TREND. LOWS AND ESPECIALLY HIGHS SHOULD GO
WELL ABOVE NORMAL WITH VERY DRY CONDITIONS. GAH

.LONG TERM...WEDNESDAY NIGHT THROUGH MONDAY...
UPPER RIDGE MOVES TO THE EAST WEDNESDAY NIGHT AND UPPER TROUGH/LOW
TO THE WEST MOVES INLAND FROM THE PACIFIC. A SLOW MOVING COLD
FRONT WILL MOVE THROUGH THE FORECAST AREA WEDNESDAY NIGHT AND
THURSDAY. THE FRONT WILL BE PARALLEL TO THE SOUTHERLY FLOW ALOFT
WHICH WILL CAUSE IT TO BECOME NEARLY STATIONARY NEAR THE
MONTANA/DAKOTA BORDER THURSDAY NIGHT AND FRIDAY. WILL SEE LIMITED
MOISTURE ALONG THIS FRONT UNTIL THE SHORTWAVE MOVING AROUND THE
UPPER LOW TO THE WEST REACHES EASTERN MONTANA THURSDAY NIGHT.
THURSDAY NIGHT AND FRIDAY...MODELS AGREE ON BRINGING DECENT
MOISTURE INTO EASTERN MONTANA WITH MULTIPLE SHORTWAVES. WILL TREND
CHANCE OF PRECIP UP BUT HOLD OFF ON GOING LIKELY AS THE LAST FEW
SYSTEMS HAVE TURNED OUT TO BE MUCH DRIER THAN FORECASTED BY THE
MODELS. WILL ALSO NEED TO WATCH TEMPERATURES AS IT MAY BE COLD
ENOUGH FOR SNOW ESPECIALLY AT NIGHT.

UPPER TROUGH LINGERS OVER MONTANA THROUGH THE WEEKEND WITH AN
UPPER LOW OVER ALBERTA. BY SATURDAY MORNING...THE MAIN SHORTWAVE
MOVES INTO THE DAKOTAS TAKING THE MOISTURE WITH IT AND DIMINISHING
THE CHANCES OF RAIN OR SNOW TO SLIGHT CHANCE. MODELS EVENTUALLY
MOVE THE UPPER LOW TO THE EAST ON SUNDAY WITH ONE MORE SHORTWAVE
MOVING THROUGH THE AREA BEFORE TURNING THE FLOW ALOFT TO THE
NORTHWEST FOR EARLY NEXT WEEK. WITH LIMITED MOISTURE...WILL KEEP
FORECAST MAINLY DRY AFTER SATURDAY WITH TEMPERATURES AT OR BELOW
NORMAL. FORRESTER
