AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
114 PM MDT THU JUL 24 2014

.SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT. DRY WEATHER WILL
CONTINUE AS WE HEAD INTO THE WEEKEND. WE ARE SEEING FULL MIXING OF
STRONG WINDS AND VERY DRY ALOFT TO THE SURFACE THIS AFTERNOON.
SUSTAINED WINDS OF 15-30 MPH WITH HIGHER GUSTS ARE COMMON...WITH
SUSTAINED WINDS UPWARDS OF 35 MPH ARE ONGOING ACROSS PORTIONS OF
THE SNAKE PLAIN. NEEDLESS TO SAY...THE WIND ADVISORY WILL REMAIN
IN EFFECT THROUGH THIS EVENING ACROSS THE SNAKE PLAIN. WITH DRY
AIR IN PLACE...WE WILL SEE RATHER COOL OVERNIGHT LOWS DURING THIS
PERIOD. THERE WILL BE PLENTY OF 40S FOR THE VALLEYS AND 20S/30S IN
THE MOUNTAINS. IN FACT...SOME HIGHER MOUNTAIN VALLEYS WILL SEE A
FREEZE TONIGHT. WE WILL BE FLIRTING WITH RECORDS TONIGHT FOR
STANLEY...CHALLIS AND IDAHO FALLS. A GAP WIND WILL KEEP THINGS A
BIT WARMER FOR POCATELLO AND BURLEY. ON THE FLIP SIDE...THE DRY
AIR WILL ALLOW FOR A NICE WARM UP EACH AFTERNOON. TEMPERATURES
OVERALL WILL GRADUALLY WARM UP. IT WILL BE LESS BREEZY EACH DAY AS
HIGH PRESSURE SLIPS BACK TOWARD US. KEYES

.LONG TERM...SUNDAY THROUGH NEXT THURSDAY. MONSOON MOISTURE
BEGINS CREEPING BACK INTO EASTERN IDAHO FOR SUNDAY AND BEYOND. WE
MAY SEE A ROGUE DRY THUNDERSTORM DEVELOP CLOSER TO THE UTAH BORDER
SUNDAY AFTERNOON. IT APPEARS THOUGH THAT BETTER DEVELOPMENT WILL
WAIT UNTIL SUNDAY NIGHT OR MONDAY AS DEEPER MOISTURE ARRIVES.
MONDAY MAY BE THE DAY WITH BETTER COVERAGE...AS THE MODELS
CONTINUE TO SHIFT THE RIDGE AXIS BACK TO THE NORTHWEST AND OVER
THE STATE. THE MODELS ARE SHOWING MOISTURE ROTATING THROUGH
EASTERN IDAHO FOR SOME CHANCE OF THUNDERSTORMS EACH DAY. WE WILL
BACK INTO 90S AND LIKELY SOME HUMIDITY TO MAKE IT FEEL A BIT
STICKY. KEYES

&&

.AVIATION...VFR CONDITIONS ARE EXPECTED THROUGH THE PERIOD. WINDY
CONDITIONS WILL PERSIST UNTIL SUNSET AS A DRY COLD FRONT EXISTS THE
REGION. DRY AND WARM CONDITIONS WILL CONTINUE THROUGH THE WEEKEND
WITH BREEZY AFTERNOONS.

.FIRE WEATHER...GUSTY WINDS HAVE RAMPED UP AS EXPECTED TODAY ACROSS
MUCH OF THE AREA BEHIND A DRY COLD FRONT THAT HAS BEEN MOVING

BOTTOM OUT BELOW 15 PERCENT FOR MANY LOCATIONS. THE RED FLAG WARNING
FOR THE CRITICAL ZONES 422 425 427 AND 410 WILL CONTINUE THROUGH 9
PM TONIGHT. AFTER SUNSET WINDS WILL CALM...AND DRY AND WARM
CONDITIONS ARE EXPECTED TO CONTINUE THROUGH THE WEEKEND. THE NEXT
CHANCE OF THUNDERSTORMS LOOKS TO RETURN SOMETIME EARLY NEXT WEEK
WITH THE RETURN OF MONSOON MOISTURE.  EP
