AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
324 AM MDT FRI AUG 10 2007

.SHORT TERM...TODAY THROUGH SUNDAY. AN AREA OF LOW PRESSURE WILL
SWING THROUGH THE INTERMOUNTAIN WEST TODAY...WITH A COLD FRONT
EXPECTED TO CROSS EASTERN IDAHO. THE COLD FRONT WILL GENERATE
BREEZY WIND CONDITIONS ACROSS MUCH OF THE AREA...ESPECIALLY OVER
THE SNAKE RIVER PLAIN BY THE AFTERNOON. AS THE LOW CENTER DRIFTS
OVERHEAD GUSTY WINDS ALOFT WILL BE ALLOWED TO MIX TO THE SURFACE.
GUSTS TO 30 MPH WILL BE POSSIBLE DURING THE PEAK HEATING OF THE
AFTERNOON. THE COMBINATION OF VERY DRY CONDITIONS AND THESE GUSTY
WINDS WILL LEAD TO A PERIOD OF CRITICAL FIRE WEATHER CONDITIONS.
IN ADDITION...A LAKE WIND ADVISORY IS IN EFFECT DURING THE AFTERNOON
AND EARLY EVENING FOR THE AMERICAN FALLS RESERVOIR. ALSO...ENOUGH
ATMOSPHERIC MOISTURE WILL BE IN PLACE THIS AFTERNOON FOR ISOLATED
THUNDERSTORM DEVELOPMENT OVER THE CENTRAL AND NORTHEAST HIGHLANDS.
CONVECTION WILL FAVOR AREAS OVER AND ALONG THE IDAHO AND MONTANA
BORDER AS WELL AS EAST AND NORTHEAST OF THE SAWTOOTH RANGE.

DRY SOUTHWEST FLOW WILL OVERSPREAD THE AREA THROUGH THE REMAINDER
OF THE PERIOD. TEMPERATURES WILL WARM TO SLIGHTLY ABOVE
NORMAL...AND DRY CONDITIONS ARE EXPECTED.

.LONG TERM...SUNDAY NIGHT THROUGH THURSDAY. THE FORECAST MODELS
ARE IN GENERAL AGREEMENT THAT A BUILDING TROUGH OF LOW PRESSURE
OVER THE PACIFIC WILL HELP TO STRENGTHEN HIGH PRESSURE OVER
EASTERN IDAHO NEXT WEEK. AS THE HIGH IS STRENGTHENED MID AND
UPPER-LEVEL MOISTURE OVER THE DESERT SOUTHWEST WILL MIGRATE INTO
THE REGION CREATING THE CHANCES FOR SHOWERS AND THUNDERSTORMS. THE
FIRST PUSH OF MOISTURE WILL OCCUR LATE MONDAY INTO TUESDAY. CANTIN

&&

.AVIATION...WIDESPREAD VFR CONDITIONS ARE EXPECTED TODAY. AN
ADVANCING SURFACE COLD FRONT COUPLED WITH WEAK DISTURBANCES EMBEDDED
IN THE INCREASING SW FLOW ALOFT MAY HELP TO TRIGGER THUNDERSTORMS
ACROSS THE CENTRAL IDAHO MOUNTAINS AND MONTANA BORDER TODAY WITH
ISOLATED MVFR CONDITIONS POSSIBLE. GUSTY SW WINDS WILL SPREAD
THROUGHOUT THE REGION THIS AFTERNOON WITH THE PASSING COLD FRONT.
HUSTON

&&

.FIRE WEATHER...A LOW PRESSURE SYSTEM SWEEPING EAST ALONG THE
CANADIAN BORDER WILL DRIVE A DRY SURFACE COLD FRONT THROUGH THE
REGION TODAY PRODUCING STRONG GUSTY WINDS. THE COMBINATION OF STRONG
WINDS AND LOW HUMIDITY THIS AFTERNOON HAS PROMPTED THE ISSUANCE OF A
RED FLAG WARNING FOR ALL ZONES THROUGH 9 PM THIS EVENING. THE UPPER
WAVE SHIFTS WELL EAST OF REGION BY SATURDAY WITH MODEST
SOUTHWEST FLOW AND STRONG LOW LEVEL MIXING PREVAILING THROUGHOUT THE
WEEKEND. THE COMBINATION OF THESE TWO FACTORS OPENS THE DOOR FOR
NEAR RED FLAG WIND GUST CONDITIONS OVER THE WEEKEND AND ESPECIALLY
SUNDAY AS A WEAK SURFACE TROUGH DEVELOPS EAST OF THE DIVIDE. WILL
ALLOW FOLLOWING SHIFTS TO ADDRESS THOSE CONCERNS AS THEY MOVE INTO
THE SHORT-TERM PORTION OF THE FORECAST. THE MODELS CONTINUE TO TRY
AND HOOK SUB-TROPICAL MOISTURE NORTH INTO THE REGION BY TUESDAY. THE
DETAILS CONTINUE TO REMAIN VAGUE DUE TO RUN TO RUN INCONSISTENCIES
IN THE MODEL SOLUTIONS. HUSTON
