NATIONAL WEATHER SERVICE POCATELLO ID
329 AM MST THU JAN 29 2015

.SHORT TERM...TODAY THROUGH SATURDAY NIGHT. LOOKING AT CURRENT
WEB CAMS ACROSS THE AREA...MOST OF THE DENSE FOG HAS LIFTED TO LOW
CEILINGS OR AREAS WITH 3 TO 5 MILES OF VISIBILITY. ONLY A FEW AREAS
LIKE RIRIE AND ANTELOPE FLATS STILL HAVE DENSE FOG. AS A
RESULT...HAVE LET THE DENSE FOG ADVISORY EXPIRE. LOOK FOR FOG
FRIDAY MORNING AS WELL BUT FOG WILL NOT BE AS WIDE SPREAD. A
SYSTEM WILL APPROACH FROM THE SOUTH FRIDAY MORNING BUT LOOK FOR
ONLY A SLIGHT CHANCE OF SNOW AND RAIN SHOWERS ALONG THE UTAH LINE.
A WAVE WILL MOVE OVER MONTANA SATURDAY BRINGING BREEZY WINDS
ACROSS THE AREA AND A SLIGHT CHANCE OF SNOW...MAINLY FOR THE
EXTREME NORTHERN AREA OF THE UPPER SNAKE HIGHLANDS. WYATT

.LONG TERM...SUNDAY THROUGH THURSDAY.
BOTH GFS AND EUROPEAN MODELS INDICATE RIDGE BREAKING DOWN A BIT
LATE SUNDAY INTO MONDAY AND HAVE HIGHEST PRECIPITATION CHANCES
MONDAY INTO TUESDAY. RIDGE REBUILDS TO WEST AND REDUCED POPS
WEDNESDAY AND THURSDAY WITH ONLY A SLIGHT CHANCE OF MAINLY
MOUNTAIN PRECIPITATION. SHOULD NOT SEE MUCH CHANGE IN
TEMPERATURES WITH WELL ABOVE NORMAL HIGH TEMPERATURES EXPECTED
THROUGH THE ENTIRE LONG TERM PERIOD. GK

&&

.AVIATION...HEIGHT OF STRATUS HAS LIFTED TO MVFR CATEGORIES AT
BYI...PIH AND IDA WHILE LOW IFR MOVED INTO SUN AFTER MIDNIGHT AS
NORTHWEST WINDS SUBSIDED THERE. DIFFICULT FORECAST WITH HIGH
UNCERTAINTY ON LEVELS OF CLOUDS AND INTENSITY OF FOG. SUN WILL
DEPEND ON WIND AS IF NORTHWEST WIND RETURNS IFR WILL CLEAR OUT
BUT COULD MOVE BACK THIS AFTERNOON WITH SOUTHEAST WIND. EXPECT AT
LEAST MVFR CONDITIONS AT BYI...PIH AND IDA TODAY AND COULD SEE A
RETURN TO IFR CEILINGS TONIGHT WHERE IT HAS LIFTED.
