.DISCUSSION...TODAY THROUGH NEXT WEDNESDAY. A CLOSED LOW STORM
SYSTEM IS STILL OVER NORTHERN IDAHO. EXPECT SCATTERED VALLEY AND
NUMEROUS MOUNTAIN SHOWERS AS WELL AS ISOLATED VALLEY AND
SCATTERED MOUNTAIN THUNDERSTORMS TODAY. ACCUMULATING SMALL
HAIL...LIGHTNING AND LOCALIZED HEAVY RAINFALL WILL AGAIN BE THE
BIGGEST IMPACTS EXPECTED TODAY. MOST HAIL WILL BE UNDER ONE HALF
INCH BUT SLIGHTLY LARGER HAIL IN LOCALIZED AREAS CANNOT BE RULED
OUT. ADDITIONALLY...LOOK FOR GUSTY WINDS IN AROUND THUNDERSTORMS.
THURSDAY THE SYSTEM STARTS TO FALL APART AND MOVE EAST BUT WILL
CONTINUE TO BRING FAIRLY GOOD PRECIPITATION CHANCES MAINLY FOR OUR
EASTERN AREAS. EXPECT PRECIPITATION MAINLY ACROSS OUR EASTERN
AREAS TO AN LESSER EXTENT ON FRIDAY AS WELL. SATURDAY CONTINUES
TO LOOK LIKE THE DRIEST DAY OF THE PERIOD WITH LIGHT SHOWERS
MAINLY ALONG THE MONTANA DIVIDE. THE MODELS ARE NOW SHOWING A VERY
WEAK WAVE MOVING ACROSS THE AREA EARLY SUNDAY BRINGING LIGHT
SHOWERS. A SYSTEM IS STILL MOVING THROUGH THE AREA ON MONDAY INTO
TUESDAY. THOUGH MODELS STILL SHOW PRECIPITATION MAINLY ACROSS OUR
NORTHERN AREAS ON MONDAY...THEY ARE NOW SHOWING A CLOSED LOW
DROPPING OVER OUR AREA ON TUESDAY INTO WEDNESDAY BRINGING GOOD
PRECIPITATION CHANCES FOR OUR WHOLE AREA. LOOK FOR AT NORMAL OR
SLIGHTLY BELOW NORMAL TEMPERATURES EARLY IN THE PERIOD BEFORE
CLIMBING ABOVE NORMAL BY SATURDAY. TEMPERATURES WILL REMAIN ABOVE
NORMAL THROUGH MONDAY WITH TEMPERATURES IN THE LOW TO MID EIGHTIES
FOR LOWER ELEVATIONS PARTICULARLY ON SUNDAY. TEMPERATURES DROP TO
NEAR NORMAL TO SLIGHTLY BELOW NORMAL AGAIN BY TUESDAY AND CONTINUE
THROUGH WEDNESDAY. WYATT

.AVIATION...PLENTY OF BOUNDARY-LAYER MOISTURE AROUND IDAHO FALLS
AFTER YESTERDAY`S RAINFALL. WITH SKIES CLEARING...FOG IS A
POSSIBILITY THROUGH MID-MORNING. THIS MAY CREEP INTO THE POCATELLO
AREA THIS MORNING AS WELL AS INDICATED BY BRIEF LOWER CIGS ON THE
NAM MOS. FORECAST SOUNDINGS SHOW CONDITIONS RAPIDLY DESTABILIZING
AROUND NOON WHICH COULD LEAD TO ANOTHER REPEAT OF SHOWERS AND
ISOLATED THUNDERSTORMS.  HINSBERGER

&&

.FIRE WEATHER...SCATTERED TO NUMEROUS SHOWERS AND ISOLATED TO
SCATTERED THUNDERSTORMS ASSOCIATED WITH AN UPPER LOW WILL BE THE
MAIN THREAT FOR THIS AFTERNOON AND EVENING. THE LOW WILL SLOWLY
MOVE SOUTHEAST ACROSS CENTRAL IDAHO THIS AFTERNOON AND THROUGH
LEMHI COUNTY BY LATE TONIGHT. TOMORROW WILL BRING ANOTHER ROUND OF
SHOWERS AND ISOLATED THUNDERSTORMS AS THE UPPER LOW CONTINUES TO
SLOWLY TRACK SOUTHEASTWARD INTO WYOMING. A DRYING TREND IS IN
STORE FOR FRIDAY. MOUNTAIN SHOWERS/THUNDERSTORMS MAY RETURN BUT
WILL BE MUCH LESS WIDESPREAD. CONDITIONS SHOULD REMAIN FAIRLY DRY
AS WE HEAD INTO THE WEEKEND. HINSBERGER
