AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
249 AM MDT WED SEP 12 2012

.SHORT TERM...TODAY THROUGH FRIDAY. A RIDGE OF HIGH PRESSURE WILL CONTINUE TO
BUILD IN TO THE AREA THROUGH FRIDAY AND PRODUCE DRY CONDITIONS.  THE
DRY AIR...ALONG WITH COLDER AIR FROM THE NORTH WILL COMBINE TO DROP
OVERNIGHT TEMPERATURES ACROSS THE ENTIRE AREA EVEN LOWER THAN WE
HAVE SEEN THE PAST TWO NIGHTS. LOWS WILL BE IN THE 30S IN THE
VALLEYS FOR THURSDAY MORNING.  PLACES SUCH AS STANLEY AND COPPER
BASIN WILL SEE LOWS IN THE TEENS. A FROST ADVISORY WILL BE IN EFFECT
FOR THE SNAKE RIVER VALLEY THURSDAY MORNING FROM 10Z TO 15Z.
OTHERWISE... TEMPERATURES WILL BEGIN TO WARM THROUGHOUT THE AREA
WITH HIGHS IN THE VALLEYS IN THE 70S ON THURSDAY AND 80S WILL RETURN
BY FRIDAY AFTERNOON.

.LONG TERM...SATURDAY THROUGH WEDNESDAY. THE RIDGE OF HIGH PRESSURE WILL BE
MOVING OFF TO OUR EAST AND A SOUTHWESTERLY FLOW WILL GIVE WAY TO OUR
NEXT TROUGH WHICH LOOKS TO ARRIVE ON SUNDAY. THE MODELS ARE STILL IN
A DISAGREEMENT AS TO THE INTENSITY AND EXACT ARRIVAL TIME OF THIS
SYSTEM.  THE GFS IS SUGGESTING A WEAKER SYSTEM THAT IS DRY. THE
EUROPEAN MODEL IS CALLING FOR A STRONGER MID-LEVEL LOW TO DEVELOP
WITH MORE MOISTURE AND COOLER TEMPERATURES.  THE MORNING FORECAST IS
CURRENTLY LEANING TOWARD A SMALL CHANCE OF PRECIPITATION IN THE
HIGHER ELEVATIONS WITH SLIGHTLY COOLER TEMPERATURES. A NORTHWESTERLY
FLOW IS EXPECTED TO RETURN NEXT WEEK WITH ANOTHER RIDGE OF HIGH
PRESSURE.
