AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
159 PM MDT WED JUL 3 2013

.SHORT TERM...UPPER AIR SOUNDING AT BOISE THIS MORNING SHOWED
PRECIPITABLE WATER AT 1.34 INCH...CLOSE TO 4 STANDARD DEVIATIONS
ABOVE NORMAL. IN SATELLITE IMAGERY...THE DEEPER MOISTURE OVER
SOUTH EAST OREGON SHOULD ROTATE AROUND THE CENTER OF THE HIGH
PRESSURE RIDGE LOCATED NEAR THE EXTREME SOUTHEAST CORNER OF IDAHO.
EXPECT THIS WILL ENHANCE SHOWERS AND THUNDERSTORMS IN WESTERN
CASSIA COUNTY AREA THIS AFTERNOON AND EVENING....INCLUDING THE
MINIDOKA WILDFIRE COMPLEX FROM 2012 JUST WEST OF OAKLEY. HAVE
ISSUED A FLOOD WATCH FOR FLASH FLOODING FOR THAT AREA. QUICK RUN
OFF FROM HYDROPHOBIC SOILS MAY ONLY NEED A QUARTER INCH OF RAIN TO
CAUSE MUD OR ASH SLIDES. IN THE MEANTIME...COMPLEX SHEARED FLOW

AREA....WHILE BREAKS IN CLOUDS SOUTH TOWARDS BURLEY ALLOW MORE
SURFACE HEATING. SOME CONVECTION BEGINNING ACROSS THE BORDER IN
NEVADA. MAY TAKE A COUPLE HOURS YET BEFORE CASSIA COUNTY SEES
THUNDERSTORMS. RS

.LONG TERM...A LOW PRESSURE TROUGH IN THE PACIFIC NORTHWEST SUNDAY AND MONDAY
WILL CONTINUE TO SUPPRESS THE HIGH PRESSURE RIDGE AND IT EVENTUALLY
CROSSES INTO THE UPPER MID WEST TUESDAY AND WEDNESDAY A LITTLE
REBOUND OF THE HIGH PRESSURE RIDGE. THE ECMWF SHOWS MORE DRY AIR
NOSING INTO THE CENTRAL MOUNTAINS IN KEEPING WITH YESTERDAYS GFS
MODEL WHICH SUPPORTS LOWERING THE CHANCE OF PRECIPITATION MID WEEK A
BIT. VALLEY TEMPERATURES RETURN TO THE LOWER 90S...ABOVE
NORMAL...BUT NOT THE RECORD HEAT OF THE PAST FEW DAYS. RS

WITH WIND GUSTS NEAR 40 MPH. WYATT
