AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
311 AM MDT FRI JUL 18 2014

.SHORT TERM...TODAY THROUGH SATURDAY NIGHT. MONSOON MOISTURE
WILL CONTINUE TO SIT JUST TO OUR SOUTH THROUGH THE FIRST PART OF
THE WEEKEND. THE MODELS HAVE BEEN TRENDING FARTHER SOUTH EACH RUN
WITH THIS...SO WE HAVE BEEN SLOWLY WHITTLING AWAY AT THUNDERSTORMS
IN THE MOUNTAINS NEAR THE UTAH BORDER. WE STILL HAVE ISOLATED
STORMS IN THROUGH THIS EVENING...THEN AGAIN TOMORROW AFTERNOON AND
NIGHT. IF THE TREND CONTINUES WE WILL LIKELY BE REMOVING ANY
CHANCE OF STORMS UNTIL SUNDAY. ACROSS THE NORTH...THE TAIL END OF
A STORM WILL CLIP THE AREA FOR ISOLATED STORMS IN THE MOUNTAINS
NORTH OF ARCO TO ISLAND PARK. ANY STORMS THAT DEVELOP COULD
PRODUCE GUSTY WINDS AND LIGHT RAINFALL AMOUNTS. OTHERWISE...JUST
SOME OCCASIONAL CLOUDS ACROSS THE REST OF EASTERN IDAHO. IT WILL
BE BREEZY BOTH AFTERNOONS AS WE WILL SEE SOME MIXING OF WINDS FROM
SEVERAL THOUSAND FEET ABOVE THE SURFACE. RIGHT NOW...THOUGH IT
APPEARS THAT WINDS ARE BORDERLINE FOR A LAKE WIND ADVISORY FOR
AMERICAN FALLS RESERVOIR. THEREFORE...WE WILL FORGO ISSUING ONE
AT THIS TIME. HOWEVER...YOU WILL NEED TO WATCH THE WATER ON ANY
LAKE OR RIVER YOU ARE OUT ON IN CASE THE CHOP GETS A LITTLE ROUGH.
TEMPERATURES WILL REMAIN ABOVE AVERAGE...WITH A SLIGHT COOL DOWN
FOR LOCATIONS SATURDAY.  KEYES

.LONG TERM...SUNDAY THROUGH NEXT FRIDAY. THE MODELS CONTINUE TO
PUSH THE ARRIVAL OF MONSOON MOISTURE AND A BETTER CHANCE OF
SHOWERS/STORMS UNTIL LATER SUNDAY AND MONDAY. THE FORECAST WILL
REFLECT THAT TREND. THIS WILL ALSO BE THE TIMEFRAME WE WOULD SEE A
LITTLE MORE RAIN FALLING WITH STORMS DUE TO THE AMOUNT OF MOISTURE
IN THE AIR. ALTHOUGH THE MODELS ARE NOT QUITE IN TOTAL SYNC WITH
EACH OTHER FOR MIDWEEK...IT DOES APPEAR THAT SHOWERS AND STORMS SHOULD
BE CONFINED TO THE CENTRAL MOUNTAINS AND PARTS OF THE UPPER SNAKE
HIGHLANDS. ONCE THE LOW TO OUR NORTHWEST DURING THIS PERIOD
FINALLY SCOOTS INTO SOUTHERN CANADA...WE WILL DRY CONDITIONS
HEADING TOWARD NEXT WEEKEND AS THE FOUR CORNERS HIGH BUILDS INTO
OUR AREA. AFTER COOLING DOWN EARLY NEXT WEEK DUE TO THE INCREASED
CLOUD AND STORM COVERAGE...TEMPERATURES WILL PUSH BACK TO ABOVE
AVERAGE. WE WILL ALSO THE WIND KICKING UP IN THE AFTERNOON AND
EVENING HOURS EACH DAY.  KEYES

&&

.AVIATION...A DRY AND STABLE WNW FLOW ACROSS THE REGION TODAY WILL
INHIBIT THUNDERSTORM DEVELOPMENT AND SUPPORT LOCALLY GUSTY AFTERNOON
WINDS PARTICULARLY WITHIN THE SNAKE RIVER PLAIN. HUSTON

&&

.FIRE WEATHER...THE LATEST SATELLITE IMAGERY WAS SHOWING THE PACIFIC
STORM TRACK ARCHING OVER A BROAD UPPER RIDGE WITHIN THE ERN PACIFIC
INTO WRN CANADA. SEVERAL DISTURBANCES WERE EMBEDDED IN THIS FLOW
WITH THE NEXT UPSTREAM LOW EXPECTED TO PUSH EAST INTO WRN CANADA
TODAY NUDGING THE STORM TRACK A LITTLE FURTHER SOUTH WITH A
CORRESPONDING INCREASE IN WINDS ACROSS THE REGION. NUMERICAL MODELS
SUGGEST ENOUGH MIXING AND WIND THIS AFTERNOON TO SUPPORT A MARGINAL
RED FLAG EVENT WITHIN THE SNAKE RIVER PLAIN FOR ZONES 425 AND 410.
BORDERLINE CONDITIONS ARE LIKELY AGAIN SATURDAY AS THE UPPER LOW
CONTINUES TO PROGRESS EAST THROUGH CANADA AND A SURFACE TROUGH
DEVELOPS ACROSS CNTRL MONTANA/SASKATCHEWAN. WILL HOLD OFF ON
EXTENDING THE FIRE WEATHER HIGHLIGHTS INTO SATURDAY UNTIL WE SEE HOW
TODAY SHAKES OUT. A SECOND PAC LOW APPROACHES THE CANADIAN COAST
SUNDAY WHILE A SURGE OF SUB-TROPICAL MOISTURE BEGINS TO LIFT NORTH
ACROSS NEVADA. THE LEADING EDGE OF THE SUB-TROPICAL MOISTURE
SPREADS INTO SRN IDAHO LATE SUNDAY AFTERNOON AND CONTINUES THROUGH
TUESDAY RESULTING IN SCATTERED SHOWERS AND THUNDERSTORMS EARLY NEXT
WEEK. BY WEDNESDAY OR THURSDAY...THE LOW LIFTS NE INTO CANADA
RESULTING IN DRY AND BREEZY CONDITIONS. THE 4-CORNERS HIGH SPREADS
NORTH ACROSS THE GREAT BASIN FRIDAY WITH A RETURN TO HOT CONDITIONS
LEADING INTO THE WEEKEND. HUSTON

.PIH WATCHES/WARNINGS/ADVISORIES...
RED FLAG WARNING FROM 1 PM THIS AFTERNOON TO 9 PM MDT THIS
EVENING FOR EASTERN IDAHO FIRE ZONES 410 AND 425.
