AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE POCATELLO ID 201 PM MDT TUE JUN 29 2010 .SHORT TERM...CLOUD COVER HAS HELPED HOLD SURFACE TEMPERATURES BACK SOME THIS AFTERNOON...BUT AIRMASS HAS BECOME MORE UNSTABLE FROM PORTIONS OF NORTHEAST NEVADA TO ABOUT BELLEVUE AS SUGGESTED BY SATELLITE DERIVED LIS...AND CONVECTION IS PICKING UP SOME IN THAT AREA. THE BIGGER FOCUS IS ON EMBEDDED WAVE MOVING INTO NORTHERN CALIFORNIA. THAT DISTURBANCE SHOULD TRACK INTO CENTRAL IDAHO LATER THIS EVENING. BELIEVE THE AIRMASS WILL REMAIN UNSTABLE ENOUGH FOR THUNDERSTORMS TO BE ACTIVE WELL PAST MIDNIGHT AS THAT DISTURBANCE MOVES TOWARDS MONTANA. SURFACE ANALYSIS ALSO SHOWS A LOW PRESSURE CENTER IN EXTREME NORTHEAST NEVADA. THE NAM12 MODEL MOVES A LOW FROM THAT AREA TOWARDS POCATELLO AND ALONG THE EAST SIDE OF THE SNAKE PLAIN CLOSER TO MIDNIGHT. MODELS HAVE ALSO BEEN FLIRTING WITH DOWN DRAFT POTENTIAL OF 50 PLUS MPH THE PAST FEW RUNS. THAT COULD BE MODIFIED SOME BY MOISTURE ACTUALLY PRESENT...BOISE 12Z SOUNDING PRECIPITABLE WATER WAS .89 INCH. SOUTHWESTERLY FLOW ALOFT WILL PREVAIL OVER SOUTHEAST IDAHO WEDNESDAY THROUGH FRIDAY. THE THREAT OF CONVECTION RECURS EACH AFTERNOON. THE LATEST GFS MODEL RUN SHOWS DRIER AIR CROSSING NEVADA. THAT CAN LIMIT SHOWERS AND PRECIPITATION BUT ALSO ALLOW MORE HEATING FOR THUNDERSTORM DEVELOPMENT. THE PROLONGED TROUGHING WILL MODERATE TEMPERATURES 5 TO 10 DEGREES AND COULD CONTINUE THROUGH THE 4TH OF JULY AS THE LATEST GFS SHOWS A SECOND SPOKE ON THE LOW MOVING THROUGH ABOUT SUNDAY. RS && .AVIATION...SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP THIS AFTERNOON AND WILL LIFT NORTHWARD ACROSS THE AREA INTO THE EARLY MORNING HOURS. VERY STRONG WIND GUSTS WILL BE A THREAT WITH THESE STORMS DUE TO DRY AIR AT THE LOWER LEVELS. ISOLATED TO SCATTERED THUNDERSTORMS WILL AGAIN BE POSSIBLE ON WEDNESDAY WITH THE GREATEST POTENTIAL IN THE CENTRAL MOUNTAINS. VFR CONDITIONS ARE OTHERWISE EXPECTED. && .FIRE WEATHER...SCATTERED THUNDERSTORMS ARE EXPECTED THROUGHOUT THE AREA TONIGHT BUT WILL BECOME MORE FOCUSED ON THE HIGHER TERRAIN ON WEDNESDAY. GUSTY WINDS AND MODERATE LIGHTNING WILL BE A THREAT WITH THESE STORMS. A SLOW MOVING AND BROAD SYSTEM WILL LINGER INTO THE WEEKEND. EXPECT COOLER TEMPERATURES FOR FRIDAY AND SATURDAY AND ISOLATED MOUNTAIN SHOWERS AND THUNDERSTORMS FOR THE LATER HALF OF THE WEEK. && .PIH WATCHES/WARNINGS/ADVISORIES...NONE. &&
