...MINOR UPDATES PLANNED TO ZONES AND STATE...
.SHORT TERM...CURRENT FORECAST HAS SITUATION HANDLED WELL. LIGHT
RAIN SHOWERS EXITING THE NORTHEAST ZONES...SO WILL ADJUST FORECAST
ACCORDINGLY THERE. CLOUDS DECREASING ALSO...AND TREND IS IN THE
FORECAST. MAY SEE MORE SUN THAN CURRENTLY ADVERTISED...BUT NO SENSE
IN SPLITTING HAIRS BETWEEN MOSTLY SUNNY AND PARTLY CLOUDY WORDING.

HIGH WIND WARNING WILL BE EXPANDED TO INCLUDE THE ZONES ADJACENT TO
ROCKY MOUNTAIN FRONT. WINDS TAME AT THIS POINT...BUT WILL INCREASE
LATER THIS MORNING AS POORLY DEFINED COLD FRONT MOVES INTO CWA. WITH
COLD AIR ADVECTION AND INSTABILITY...BELIEVE THERE WILL BE EFFICIENT
MIXING DOWN TO SURFACE OF FORECAST 55 TO 60 KT WINDS BETWEEN 700 AND
750 MB.

POST COLD FRONT INSTABILITY THIS AFTERNOON IS IMPRESSIVE...WITH
MESOETA CROSS SECTIONS SHOWING VERTICAL VELOCITY VALUES AS HIGH AS
HAS BEEN SEEN FOR A WHILE. BUT AS NOTED IN PREVIOUS DISCUSSIONS...AIR
MASS WILL BE DEVOID OF MOISTURE...SO LACK OF POPS OVER LOWER
ELEVATIONS IS APPROPRIATE. ISOLATED INSTABILITY SHOWERS SHOWING UP ON
MSX RADAR THIS MORNING...BUT DOWNSLOPE ON OUR SIDE OF THE MOUNTAINS
WILL KILL THIS ACTIVITY.

.EXTENDED...ALL MODELS AGREE ON A NORTHWEST FLOW ALOFT OVER THE
REGION THROUGH OUT THE EXTENDED PERIOD AND THATS ABOUT ALL THEY
AGREE ON. THE ECMWF...CANADIAN AND THE UKMET ALL INDICATED A QUITE
NORTHWEST FLOW WITH LITTLE ACTIVITY FOR SHORT WAVES. MEANWHILE...THE
AVN AND THE MRF ADVERTISE A MORE ACTIVE NORTHWEST FLOW. NOT
CONFIDENT IN ANY SOLUTION...THEREFORE WITH THE NORTHWEST FLOW WILL
KEEP A CHANCE OF SNOW SHOWERS OVER THE MOUNTAINS AND HAVE
TEMPERATURES NEAR NORMAL. MEIER

A high wind event moved across north central Montana on the 12th. Sustained wind speeds of 40 to 50 mph were very common throughout the afternoon, and into the evening hours. Wind gusts were near 70 mph during the peak of the event. These winds started to increase in strength around 1100 MST and then they did not diminish until 2000 MST. The peak wind speeds occurred between 1300 MST and 1600 MST. Due to the very strong winds, blowing dust became a real hazard. The blowing dust reduced visibilities to near zero in many locations for a period of time. As a result of the near zero visibilities, a 12 vehicle accident occurred about 13 miles Southeast of Great Falls near 1330 MST, resulting in 2 fatalities and 4 injuries.Power was knocked out to over 1500 customer in the Great Falls metro area. A few trees were uprooted and several roofs were blown off as well. Near 1745 MST a train was blown off the tracks, just west of East Glacier, at the Midvale trestle. A total of 20 cars and 24 box containers were blown off the track. Wind speeds were estimated to be near 80 mph at the time of the accident.Some of the peak wind speeds recorded during the day were; Great Falls 68 mph at 1330 MST: Conrad 20 SE 68 mph at 1330 MST; Browning 62 mph at 1555 MST; Havre 50 mph at 1756 MST; Boulder 64 mph at 1951 MST, and Lewistown 51 mph at 1954 MST.
