AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE POCATELLO ID 147 PM MDT MON JUL 4 2011 .DISCUSSION... CONSIDERABLE AMOUNT OF CLOUD COVER OVER EASTERN IDAHO HAS KEPT TEMPERATURES COOL INTO THE EARLY AFTERNOON. TEMPERATES SHOULD RISE QUICKLY IN THE AFTERNOON HEAT AND EXPECT THUNDERSTORM DEVELOPMENT OVER THE SOUTHERN AND EASTERN HIGHLANDS AND ALONG THE MONTANA BORDER. MUCH OF THIS ACTIVITY SHOULD DIMINISH AFTER SUNSET. MORE ISOLATED THUNDERSTORMS ARE EXPECTED TUESDAY INTO WEDNESDAY AS MONSOONAL MOISTURE CONTINUES TO MOVE THROUGH THE REGION. THE SOUTHEAST HIGHLANDS WILL CONTINUE TO HAVE THE BEST CHANCES FOR DEVELOPMENT. A COLD FRONT IS EXPECTED TO ARRIVE ON THURSDAY. THIS WILL MIX WITH A HEALTHY PUSH OF MOISTURE FROM THE SOUTH TO PRODUCE THE BEST CHANCES FOR THUNDERSTORMS AREAWIDE. AM TEMPTED TO RAISE CHANCES...BUT WOULD PREFER TO SEE ANOTHER RUN OR TWO FIRST. WOULDNT BE SURPRISED IF A FEW STORMS PRODUCE STRONG GUSTY WINDS. THIS WILL BE TRUE EACH DAY...BUT ESPECIALLY ON THURSDAY WITH THE AID OF THE COLD FRONT. COOLER TEMPS...CLOSER TO NORMAL ARE EXPECTED FRIDAY AND INTO THE WEEKEND. THE MONSOONAL MOISTURE SHOULD HANG AROUND WHICH WILL CONTINUE THE ISOLATED THUNDERSTORMS. VALLE && .AVIATION...WV IMAGERY SHOWS MOISTURE PLUME FROM THE SOUTHWEST BEING SHUNTED INTO WYOMING. SOME EARLY AFTERNOON CLEARING WILL LEAD DESTABILIZATION OF THE LOW LEVELS AND SOME MORE CONVECTIVE DEVELOPMENT...ESPECIALLY OVER THE MOUNTAINS. GUIDANCE SHOWS 30 TO 35 PERCENT TS CHANCES THIS AFTERNOON INTO EARLY EVENING. HAVE WORKED VCTS IN TAFS WITH TEMPO GUSTS IN THE LATTER HALF OF THE AFTERNOON. HINSBERGER && .FIRE WEATHER...MONSOON MOISTURE WILL CONTINUE SURGING THROUGH SOUTHEAST IDAHO OVER THE COMING WEEK. THIS WILL BRING CHANCES OF ISOLATED THUNDERSTORMS MAINLY OVER THE SOUTHERN AND EASTERN HIGHLANDS. THESE STORMS SHOULD CARRY LITTLE PRECIPITATION WITH THEM AND GUSTY WINDS WITH SUDDEN WIND SHIFTS. HINSBERGER && .PIH WATCHES/WARNINGS/ADVISORIES... NONE. &&
