AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
339 AM MDT WED AUG 22 2007

.SHORT TERM...TODAY THROUGH FRIDAY. CWA REMAINS UNDER THE
INFLUENCE OF THE JET STREAM ALBEIT WITH LITTLE MOISTURE. NEXT WAVE
TO MOVE ACROSS THE AREA LATER TODAY SHOULD BRING THE BEST CHANCE
OF PRECIPITATION TO THE EASTERN AND SOUTHERN HIGHLANDS. OTHERWISE
COMFORTABLE TEMPERATURES WILL AGAIN RULE BUT LESS WIND THAN
YESTERDAY. ANOTHER COMFORTABLE DAY THURSDAY WITH REASONABLE
TEMPERATURES AND LITTLE WIND BEFORE WARMING BEGINS FRIDAY.

.LONG TERM...FRIDAY NIGHT THROUGH WEDNESDAY. PERIOD DOES NOT SHOW
MUCH IN THE WAY OF PRECIPITATION BUT OUR TEMPERATURES DO WARM OVER
THE WEEKEND. A QUICK HITTING TROUGH BRINGS A FEW DEGREES OF
COOLING SUNDAY BUT WE WARM RIGHT BACK UP MONDAY AND TUESDAY. ONE
THING TO KEEP AN EYE ON IS THE MOISTURE REMNANT FROM DEAN. SO FAR
NO INDICATION WITH PRESENT FLOW PATTERN THAT THE MOISTURE WOULD
WORK ITS WAY UP THIS FAR NORTH BUT IT IS WORTH WATCHING.
