AREA FORECAST DISCUSSION

307 AM MDT TUE JUL 11 2006

.SHORT TERM...TODAY THROUGH THURSDAY...A WEAK FRONT WILL PASS
THROUGH EASTERN IDAHO DURING THE SHORT TERM PERIOD. THESE FRONTS
WILL MAINLY IMPACT WINDS ACROSS THE AREA...WITH SOME CONVECTION
POSSIBLE AS WELL. THE FIRST FRONT...NOW APPARENT IN SATELLITE
IMAGERY WEST OF WASHINGTON AND OREGON...WILL PASS THROUGH THE
REGION OVERNIGHT. AHEAD OF THE FRONT TIGHTENING PRESSURE GRADIENTS
ALONG WITH WARM AIR ALOFT WILL MAKE FOR NEAR BREEZY AND VERY
DRY/WARM CONDITIONS. A POCKET OF MID AND UPPER-LEVEL MOISTURE OVER
NORTHERN UTAH THIS MORNING WILL BE ADVECTED OVER EASTERN IDAHO BY
THE AFTERNOON. THE COMBINATION OF VERY WARM SURFACE
TEMPERATURES...THIS MOISTURE...AND TERRAIN WILL INSTIGATE ISOLATED
SHOWERS/THUNDERSTORMS OVER THE EASTERN AND SOUTHEASTERN HIGHLANDS.
ENOUGH DRY AIR WILL EXIST OVER THE CENTRAL AND NORTHERN HIGHLANDS
TO LIMIT CONVECTION TO AREAS VERY CLOSE TO THE MONTANA AND WYOMING
BORDERS. FIRE WEATHER CONCERNS FOR THE LOWER SNAKE RIVER PLAIN AND
EASTERN MAGIC VALLEY WILL BE THE MAIN FOCUS TODAY.

OVERNIGHT THE FRONT WILL MOVE THROUGH AND ISOLATED THUNDERSTORMS
WILL AGAIN BE A POSSIBILITY OVER HIGHER TERRAIN NEAR THE WYOMING
AND MONTANA BORDERS. WINDS WILL INCREASE TO BREEZY CONDITIONS
BEHIND THE FRONT DURING THE AFTERNOON WEDNESDAY...AND TEMPERATURES
WILL SEE 3 TO 7 DEGREES OF COOLING AT MOST LOCATIONS. DRY AND WARM
SOUTHWESTERLY FLOW WILL PUSH OVER THE REGION LATE WEDNESDAY
THROUGH THURSDAY...WITH TEMPERATURES REMAINING SLIGHTLY ABOVE NORMAL.

.LONG TERM...THURSDAY NIGHT THROUGH MONDAY...HIGH PRESSURE IS
EXPECTED TO REBOUND NORTHWARD OVER THE REGION. THIS WILL KEEP WARM
TEMPERATURES AND DRY CONDITIONS IN PLACE. LATE IN THE WEEKEND
FORECAST MODELS ARE INDICATING A SMALL PUSH OF MONSOONAL MOISTURE
TO MOVE CLOSE TO AREAS NEAR THE UTAH BORDER. HAVE INDICATED A
SLIGHT CHANCE OF SHOWER ACTIVITY DURING THIS PERIOD...HOWEVER
CONFIDENCE REMAINS LUKE WARM AT THIS POINT.

&&

.AVIATION...VFR CONDITIONS WILL AGAIN BE THE RULE TODAY...WITH
ISOLATED THUNDERSTORMS POSSIBLE OVER NORTHERN AND EASTERN MOUNTAIN
AREAS.  THESE STORMS WILL AFFECT TWEB ROUTES 340...343...AND 344
WITH STORMS GENERALLY OCCURRING AFTER 20Z.

&&

.FIRE WEATHER...A SURFACE COLD FRONT WILL CROSS THE CENTRAL
MOUNTAINS NEAR 20Z TODAY WITH WIND GUSTS TO 30 MPH DEVELOPING NORTH
OF THE SNAKE RIVER AND CONTINUING THROUGH 03Z THIS EVENING. DRY AIR
WILL FOLLOW THE FRONT LOWERING RELATIVE HUMIDITY IN ZONE 409 AREA
WHERE THE CURRENT FIRE WEATHER WATCH HAS BEEN REPLACED WITH A RED
FLAG WARNING. ISOLATED TO WIDELY SCATTERED THUNDERSTORMS WILL ALSO
DEVELOP AGAIN TODAY IN MOST MOUNTAIN AREAS. THE BEST POTENTIAL FOR
WETTING RAINS WILL BE EASTERN ZONE 412 AND ZONE 413 WHERE SATELLITE
IMAGERY INDICATES MUCH DEEPER MOISTURE WILL BE THIS AFTERNOON.
WEDNESDAY AFTERNOON A DRY WEST TO SOUTHWEST FLOW ALOFT WILL CONTINUE
WITH PRECIPITABLE WATER VALUES LOWERING TO NEAR ONE HALF INCH. WEAK
H7 HIGH PRESSURE RIDGING WILL DEVELOP BY AFTERNOON WITH LIMITED
OROGRAPHIC SUPPORT FOR THUNDERSTORMS IN THE EASTERN HIGHLANDS. THUS
AFTERNOON THUNDERSTORMS WILL BE VERY ISOLATED.
