...A FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 715 PM MDT FOR
NORTHERN CLARK COUNTY...

AT 536 PM MDT...NATIONAL WEATHER SERVICE DOPPLER RADAR CONTINUED TO 
INDICATE THUNDERSTORMS CAPABLE OF PRODUCING FLASH FLOODING. EVEN 
AFTER THE RAINFALL HAS ENDED...FLOODING MAY OCCUR DUE TO DELAYED 
RUNOFF.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

MOST FLOOD DEATHS OCCUR IN AUTOMOBILES. NEVER DRIVE YOUR VEHICLE INTO
AREAS WHERE THE WATER COVERS THE ROADWAY. FLOOD WATERS ARE USUALLY
DEEPER THAN THEY APPEAR. JUST ONE FOOT OF FLOWING WATER IS POWERFUL
ENOUGH TO SWEEP VEHICLES OFF THE ROAD. WHEN ENCOUNTERING FLOODED
ROADS MAKE THE SMART CHOICE...TURN AROUND...DONT DROWN.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
207 PM MDT FRI SEP 16 2011

.SHORT TERM...AXIS OF THE UPPER TROUGH MOVING THROUGH SOUTHEAST
IDAHO THIS AFTERNOON. MUCH OF THE CENTRAL MOUNTAINS HAS RECEIVED
.4 TO .5 INCH OF RAIN THE PAST 24 HOURS...IN THE SNAKE PLAIN .1
TO .2 INCH. VERY ISOLATED THUNDERSTORM ACTIVITY HAS POPPED UP
ALMOST EVERYWHERE IN SOUTHEAST IDAHO AT LEAST ONCE TODAY.
CURRENTLY THERE IS A MINOR WAVE MOVING SOUTH TO NORTH THROUGH
LEMHI COUNTY...A SECOND WAVE IN EAST CENTRAL NEVADA AND A THIRD
WAVE OUT NEAR MEDFORD OREGON WHICH THE NAM12 TRACKS RIGHT ALONG
THE SOUTHERN IDAHO BORDER THROUGH SATURDAY MORNING AND COULD BE
RESPONSIBLE FOR ADDITIONAL LIGHTNING STRIKES LATER THIS EVENING.
LINGERING MOISTURE AND A DISTURBANCE CROSSING SOUTHERN ALBERTA
SATURDAY WILL SUPPORT ISOLATED SHOWERS IN THE EASTERN AND SOUTH
CENTRAL HIGHLANDS. SURFACE LOW PRESSURE IN EASTERN WYOMING AND
MONTANA SATURDAY AFTERNOON WILL SUPPORT BREEZY SOUTHWEST WINDS OF
15 TO 20 MPH IN THE UPPER SNAKE PLAIN...BUT SHORT OF ADVISORY
LEVEL. FORECAST AT THE MOMENT IS ALSO JUST SHORT OF LAKE WIND
ADVISORY CRITERIA FOR AMERICAN FALLS RESERVOIR...BUT IT WILL
PROBABLY BE A LITTLE BUMPY ON THE LAKE SATURDAY. PREVIOUS FORECAST
LOW TEMPERATURES FOR SUNDAY MORNING WERE ON THE COOL SIDE. WITH
RAIN TODAY AND HIGHER DEW POINT TEMPERATURES...LOWS WERE RAISED A
COUPLE THREE DEGREES. POTENTIAL FOR FROST IS LESS LIKELY. BY
SATURDAY NIGHT MORE WESTERLY FLOW PATTERN PREVAILS...COULD BE A
STRAY RAIN SHOWER IN THE CENTRAL OR NORTHERN MOUNTAINS.

.LONG TERM...MONDAY...ANOTHER EMBEDDED DISTURBANCE IN WESTERLY
FLOW COULD BRING AN ISOLATED SHOWER TO THE CENTRAL MOUNTAINS.
TUESDAY THROUGH THURSDAY....HIGH PRESSURE RIDGE BECOMES
ESTABLISHED AND TEMPERATURES SHOULD REBOUND TO THE MID AND UPPER
70S. RS

&&

.AVIATION...IFR CEILINGS ASSOCIATED WITH A MODERATE RAINBAND OVER
IDAHO FALLS THIS AFTERNOON WITH SKIES CLEARING AND BECOMING VFR AT
OTHER TERMINALS. KIDA SHOULD BEGIN IMPROVING AROUND MID AFTERNOON AS
THE RAIN CONTINUES EASTWARD. SHOWER DEVELOPMENT MAY BE POSSIBLE
LATER THIS EVENING AROUND THE TERMINALS. HINSBERGER

&&

.FIRE WEATHER...HIGHER HUMIDITIES ABOUND TODAY THANKS TO THE RAIN
RECEIVED OVER THE LAST 24 HOURS. SOME ISOLATED LIGHTNING STRIKES ARE
POSSIBLE THROUGH TONIGHT AS AN UPPER DISTURBANCE SWINGS THROUGH THE
STATE. EXPECT WINDS TO BE GUSTY DURING THE DAY OVER THE WEEKEND AS
HIGH PRESSURE BEGINS MOVING BACK IN. HUMIDITY WILL BE TOO HIGH FOR
RED FLAG CONDITIONS HOWEVER. DRIER WEATHER WILL MOVE INTO THE AREA
NEXT WEEK AS UPPER RIDGING BUILDS IN. TEMPERATURES WILL ALSO RISE
BACK INTO THE UPPER 70S. HINSBERGER

.PIH WATCHES/WARNINGS/ADVISORIES...NONE.
