Area forecast discussion, Jul 28, 1:46 PM MDT, 5 hours 8 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
146 PM MDT WED JUL 28 2010

.SHORT TERM...TONIGHT THROUGH SATURDAY.

SHOWERS AND THUNDERSTORMS ARE ONGOING. A LOW PRESSURE SYSTEM IS
EXPECTED TO MOVE THROUGH EASTERN OREGON AND INTO CENTRAL IDAHO
THIS EVENING. THIS LOW PRESSURE SYSTEM COMBINED WITH THE MONSOONAL
MOISTURE AND AFTERNOON HEATING WILL CONTINUE TO SUPPORT SCATTERED
TO NUMEROUS THUNDERSTORMS ACROSS THE REGION INTO THE EVENING. SOME
STORMS COULD HAVE STRONG WIND GUSTS...HAIL...FREQUENT LIGHTNING
AND HEAVY DOWNPOURS. MANY OF THESE STORMS WILL DIMINISH AFTER
SUNSET DUE TO THE LOSS OF THE AFTERNOON HEATING.

THE THREAT FOR SHOWERS AND THUNDERSTORMS WILL CONTINUE INTO
SATURDAY AS MONSOONAL MOISTURE CONTINUE TO WORK THROUGH THE
REGION. THE NAM HAS HAD MORE COVERAGE THAN THE GFS...WHICH
EXPLAINS WHY THE GFS MAX TEMPS ARE SO MUCH WARMER THAN THE NAM
GUIDANCE. THE 12Z NAM HAS BACKED OFF OF THE COVERAGE FOR THURSDAY
AND LOOKS SIMILAR TO THE GFS. PREVIOUS FORECASTS HAVE SUPPORTED
THE GFS SOLUTIONS...NOT SO MUCH THUNDERSTORM COVERAGE. SINCE THE
NAM HAS MOVED IN THAT DIRECTION FOR THURSDAY...WILL CONTINUE TO
LEAN TOWARDS THE GFS SOLUTION.

.LONG TERM...SATURDAY NIGHT THROUGH WEDNESDAY.

A COLD FRONT IS EXPECTED TO ARRIVE SATURDAY NIGHT INTO MONDAY
MORNING. THIS WILL BRING COOLER TEMPS TO THE REGION AND SHOULD
DISPLACE THE MONSOONAL MOISTURE FROM THE AREA FOR A COUPLE OF
DAYS. TRICKY PART OF THE FORECAST IS WHEN THE MONSOONAL MOISTURE
RETURNS. LATEST RUNS SUPPORT MIDWEEK.

&&

.AVIATION...SO FAR THIS AFTERNOON THUNDERSTORM ACTIVITY HAS ONLY
BEEN CLOSE TO SUN WITH NOTHING MUCH IN BYI...PIH AND IDA AREAS.
WILL KEEP VICINITY THUNDERSTORMS IN ALL TAF SITES UNTIL 9 OR 10 PM
LOCAL TIME TONIGHT.  SHOULD HAVE THUNDERSTORMS DEVELOPING ON
THURSDAY A WELL.  GUSTY WINDS NEAR THUNDERSTORMS WILL BE MAIN
AVIATION HAZARD TODAY.
GK

&&

.FIRE WEATHER...MOIST AND UNSTABLE AIR MASS REMAINS IN PLACE OVER
