AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE POCATELLO ID 152 PM MDT MON AUG 5 2013 .DISCUSSION...SOME MID LEVEL MOISTURE IS PUSHING THROUGH THE AREA. THIS MOISTURE IS JUST ENOUGH TO FIRE A FEW THUNDERSTORMS THIS AFTERNOON OVER THE MOUNTAINS AND HIGHLANDS. UPPER LEVEL RIDGE WILL REESTABLISH ITSELF OVER THE AREA ON TUESDAY AS A CLOSED LOW SITS OFF THE COAST OF NORTHERN CALIFORNIA. THIS WILL PRODUCE DRY AND SLIGHTLY COOLER WEATHER OVER THE AREA ON TUESDAY. ON WEDNESDAY THE RIDGE WILL SLOWLY GIVE WAY TO THE LOW. SLIGHT CHANCE FOR STORMS REAPPEAR IN THE FORECAST. A BETTER CHANCE EXISTS ON THURSDAY AS MODELS ARE SHOWING A GOOD PUSH OF MOISTURE WORKING INTO THE AREA FROM THE SOUTH. THE WEEKEND LOOKS UNSETTLED BUT NOT A WASHOUT AS THE LOW PRESSURE SYSTEM GRADUALLY WEAKENS AND MOVES INLAND. VALLE && .AVIATION...TROUGH MOVING THROUGH MONTANA AND CANADA HAS INCREASED WIND BUT PROVIDED LITTLE IN THE WAY OF CLOUDS. CIG AND VSBY CONTINUE UNRESTRICTED WITH -TSRA THREAT LIMITED TO AREAS DOWNWIND OF THE AIRDROMES...THE IDAHO-MONTANA BORDER. WIND TONIGHT REVERTS TO DOWNSLOPE CONDITIONS. MESSICK && .FIRE WEATHER...WINDS ARE JUST STARTING TO GUST TO CRITICAL LEVELS WHILE HUMIDITY HAS MAINLY DROPPED BELOW 15 PERCENT THRESHOLD IN THE AFFECTED AREA FOR THE RED FLAG WARNING...SO WILL CONTINUE THEM. SOME HIGH LEVEL CLOUDS FILTERING THROUGH WITH THE TROUGH THAT HAS BROUGHT THE WIND. WIND SHOULD TAPER OFF QUICKLY TONIGHT WITH SOME ACTUAL OVERNIGHT FLOW FROM THE NORTH BRINGING IN COOLER AIR. EXPECT A SLIGHT COOL DOWN IN TEMPERATURES AND A SLIGHT RISE IN THE HUMIDITY FOR TUE...BUT A QUICK SWITCH BACK TO SOUTHERLY FLOW BRINGS BACK WARMER AIR. AN UPPER LEVEL LOW CURRENTLY OFF THE CALIFORNIA COAST WILL SLOWLY EDGE EASTWARD AND PUSH INLAND. BY THU...IT SHOULD BE INFLUENCING EASTERN IDAHO WEATHER WITH A MODERATE TO STRONG SOUTHERLY AIRFLOW. THIS WILL PUSH THE UNSTABLE MOIST AIR FROM THE SUBTROPICS NORTHWARD. THE QUESTION IS HOW MUCH WILL COME NORTH AND WILL ENOUGH MOISTURE COME WITH IT TO GENERATE WET THUNDERSTORMS AND HIGH LIGHTNING ACTIVITY LEVELS. HARD TO JUDGE AT THIS TIME...BUT THUNDERSTORM THREAT GROWS FROM AFTERNOON TO AFTERNOON DURING THE PERIOD THU THROUGH SAT. TOO FAR OUT TO HAVE ANY CONFIDENCE IN THE LIGHTNING ACTIVITY EXCEEDING RED FLAG WARNING CRITERIA AT THIS TIME...BUT IT IS POSSIBLE. MESSICK && .PIH WATCHES/WARNINGS/ADVISORIES... RED FLAG WARNING UNTIL 10 PM MDT THIS EVENING IDZ410-425. RED FLAG WARNING UNTIL 10 PM MDT THIS EVENING IDZ422. RED FLAG WARNING UNTIL 10 PM MDT THIS EVENING IDZ475-476. &&
