AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
234 AM MDT FRI APR 17 2015

.SHORT TERM...TODAY THROUGH SUNDAY NIGHT. UPPER LEVEL LOW IN
SOUTHERN ROCKIES VAST ENOUGH TO PERHAPS BRING SOME INSTABILITY AND
SHOWER ACTIVITY ON SAT AFTERNOON...BUT OTHERWISE TOO DRY TO DO
MUCH ELSE DURING THIS PERIOD AS THE LOW SLOWLY SLIDES EASTWARD AND
HIGH PRESSURE AT THE WEST COAST KEEPS THE FORECAST AREA IN DRY
NORTH-NORTHWESTERLY FLOW. EXPECT NEARLY CLEAR SKIES WITH THE
EXCEPTION OF SAT/SAT NIGHT. THIS WILL MEAN LARGE TEMPERATURE
SWINGS WITH TEMPERATURES GETTING ABOVE NORMAL FOR HIGHS AND NEAR
NORMAL FOR LOWS EXCEPT SUN NIGHT...WHEN THE NORTHERLY FLOW WILL
BRING IN COLDER THAN NORMAL LOWS...MANY BELOW FREEZING. NOT MUCH
EXPECTED IN THE WAY OF WIND UNDER HIGH PRESSURE.  MESSICK

.LONG TERM...MONDAY THROUGH FRIDAY. A RIDGE OF HIGH PRESSURE WILL
PRODUCE DRY WEATHER ACROSS THE REGION ON MONDAY. A LARGE BUT SLOW
MOVING LOW PRESSURE SYSTEM WILL APPROACH THE WEST COAST ON TUESDAY.
MODELS SHOW SOME MOISTURE WORKING INTO THE REGION TUESDAY
AFTERNOON...PERHAPS PRODUCING A FEW ISOLATED SHOWERS. THE LOW WILL
MOVE ONSHORE ON WEDNESDAY AND PUMP MORE MOISTURE INTO THE REGION
RESULTING IN BETTER CHANCES FOR ISOLATED TO SCATTERED SHOWERS.
MODELS SHOW SOME INSTABILITY SO A FEW RUMBLES OF THUNDER ARE
POSSIBLE AS WELL. BEST CHANCES FOR SHOWERS ARE THURSDAY AND FRIDAY
AS THE LOW MOVES FURTHER INTO THE GREAT BASIN AND A COLD FRONT
APPROACHES THE REGION. MODELS SHOW THIS FRONT MOVING THROUGH THE
REGION ON THURSDAY WHICH WILL BRING COOLER TEMPS AND CONTINUED
SHOWERS TO THE AREA ON FRIDAY.
