AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
304 AM MDT SUN JUN 24 2007

.SHORT TERM...TODAY THROUGH TUESDAY. A LARGE LOW PRESSURE
SYSTEM...CURRENTLY SPINNING OFF THE WASHINGTON COAST...WILL TRACK
THROUGH NORTHERN WASHINGTON AND IDAHO LATE TODAY THROUGH MONDAY.
THE LOW WILL MOVE THROUGH QUICKLY AND WILL ACT TO INCREASE WIND
SPEEDS ACROSS MUCH OF THE AREA. WINDS WILL AGAIN REACH LAKE WIND
ADVISORY THRESHOLDS TODAY...SO AN ADVISORY IS IN EFFECT FOR THE
AMERICAN FALLS RESERVOIR. THESE WINDS ALONG WITH VERY LOW RH
LEVELS WILL GENERATE RED FLAG CONDITIONS OVER PORTIONS OF THE AREA
AS WELL TODAY. SEE THE FIRE WEATHER DISCUSSION BELOW FOR DETAILS. THE
STRONGEST WINDS WILL ARRIVE OVERNIGHT TONIGHT AND LINGER THROUGH
MOST OF THE DAY MONDAY. WEST TO SOUTHWEST WINDS OF 20 TO 30 MPH
WILL BE COMMON ACROSS THE SNAKE RIVER PLAIN DURING THIS PERIOD.
ELSEWHERE...LITTLE IN THE WAY OF SENSIBLE WEATHER IS
EXPECTED...EXCEPT FOR THE THREAT FOR ISOLATED THUNDERSTORMS ACROSS
THE CENTRAL AND NORTHEASTERN HIGHLANDS. THE BEST CHANCE FOR
THUNDERSTORMS WILL BE DURING THE EVENING TODAY INTO THE AFTERNOON
MONDAY...WITH CONVECTIONS FOCUSED OVER CENTRAL AND EASTERN
PORTIONS OF CUSTER COUNTY AND AREAS TO THE NORTH AND EAST.
TEMPERATURES WILL ONLY CLIMB INTO THE UPPER 60S TO LOWER 70S
MONDAY. THE PRESSURE GRADIENT WILL SLACKEN MONDAY NIGHT INTO
TUESDAY...WITH WINDS DROPPING SUBSTANTIALLY. CANTIN

.LONG TERM...TUESDAY NIGHT THROUGH SUNDAY. VERY GOOD AGREEMENT
EXISTS IN EXTENDED RANGE FORECAST MODELS. CURRENT FORECAST AGREES
WELL WITH MODEL TRENDS...SO HAVE MADE ONLY A FEW TWEAKS FOR THE
MORNING PACKAGE. AN AREA OF LOW PRESSURE WILL SET UP OFF SHORE
OVER THE PACIFIC AND PUMP UP A RIDGE OF HIGH PRESSURE OVER THE
ROCKY MOUNTAINS DURING THE PERIOD. EASTERN AND CENTRAL IDAHO WILL
BE UNDER PERSISTENT HOT AND DRY SOUTHWEST FLOW. ENOUGH MOISTURE MAY
SNEAK OVERHEAD STARTING FRIDAY FOR AFTERNOON CONVECTION OVER
HIGHLAND AREAS. CANTIN

&&

.AVIATION...WIDESPREAD VFR CONDITIONS NEXT 24HRS. UPPER LOW OFF PAC
NW COAST BEGINS TO EJECT INLAND THIS AFTERNOON/TONIGHT WITH
INCREASING SW FLOW ALOFT ACROSS REGION. STRONG SURFACE FRONTAL
PASSAGE MONDAY MORNING (09-12Z) WITH BREEZY POST-FRONTAL WINDS
CONTINUING THROUGH THE DAY. HUSTON

&&

.FIRE WEATHER...UPPER LOW POSITIONED OFF THE PACIFIC NW COAST BEGINS
TO EJECT INLAND THIS AFTERNOON/TONIGHT WITH INCREASING WINDS
EXPECTED ACROSS THE REGION THROUGH MONDAY. THE EARLY MORNING SURFACE
ANALYSIS WAS SHOWING REMNANTS OF YESTERDAYS FRONTAL BOUNDARY STILL
LINGERING OVER THE CNTRL MOUNTAINS WITH TIGHT GRADIENT OVER THE ERN
OREGON BORDER BEGINNING TO PUSH EAST VERY MUCH LIKE SATURDAY
MORNING. ANTICIPATE THAT THIS BOUNDARY WILL SURGE EAST THROUGH THE
SNAKE RIVER VALLEY THIS MORNING MUCH LIKE SATURDAY AND WITH
INCREASING FLOW ALOFT OVER THE AREA WITH APPROACHING UPPER LOW
EXPECT GUSTY WINDS TO MIX DOWN TO THE SURFACE ACROSS THE REGION. RED
FLAG WARNING CRITERIA EXPECTED TO BE REACHED IN ZONES 407/409/410
AND 412 TODAY...ZONE 413 LOOKED TOO MARGINAL SO IT WAS DROPPED FROM
HIGHLIGHT. UPPER LOW ADVANCES EAST ALONG THE CANADIAN BORDER
TONIGHT/MONDAY WITH STRONG FRONTAL PASSAGE SWEEPING THROUGH REGION
BETWEEN MIDNIGHT AND 6AM MONDAY MORNING. POST-FRONTAL WINDS WILL
REMAIN BREEZY THROUGHOUT THE DAY AS A COOLER DRIER AIRMASS PUSHES
INTO THE REGION. HUMIDITY LEVELS WILL HOVER AT OR ABOVE WARNING
CRITERIA BUT WITH PASSAGE OF FRONT AND STRONG WINDS IN ADDITION TO
INCREASED USE OF FIREWORKS THIS TIME OF YEAR BELIEVE IT WOULD BE
PRUDENT TO CONTINUE FIRE WEATHER WATCH FOR ZONES 407/409/410/412 AND
413.  GRADIENT FLOW RELAXES MONDAY NIGHT WITH A RETURN OF DRY AND
WARM SOUTHWEST FLOW BY TUESDAY. GOOD TEMPERATURE RECOVERY
ANTICIPATED TUESDAY AND BEYOND AS NEXT LOW PRESSURE SYSTEM SETS UP
OFF THE PAC NW COAST. HUSTON
