GUSTY WINDS WILL PERSIST COME THURSDAY, WITH THE HIGHEST GUSTS
IN THE SNAKE RIVER PLAIN. THURSDAY AFTERNOON, THE CHANCE OF 30+
MPH GUSTS ARE 80% OR GREATER FROM MOUNTAIN HOME EAST THROUGH
TWIN FALLS. HAVE UPPED THE FORECAST WINDS TO INCLUDE GUSTS OF
45-50 MPH IN THE SAME AREA DESCRIBED ABOVE. WHILE THIS IS WHERE
THE STRONGEST WINDS WILL BE SEEN, IT WILL BE BREEZY AREA-WIDE
THURSDAY FOLLOWING THE COLD FRONTAL PASSAGE. TEMPERATURES ON
THURSDAY WILL COOL TO NORMAL OR BELOW, BEFORE A WARMING TREND
ESTABLISHES ITSELF FRIDAY AND BEYOND.
NORTHWEST FLOW ALOFT WILL DOMINATE THROUGHOUT THE MAJORITY OF
THE LONG-TERM PERIOD, AS HIGH PRESSURE BUILDS IN OVER THE
NORTH PACIFIC AND A LOW CLOSES OFF NEAR THE BAJA PENINSULA.
WHILE BY SATURDAY THE RIDGING IN THE NORTH PACIFIC WILL EXTEND
EAST OVER OUR AREA, THERE WILL BE ENOUGH MOISTURE TRANSPORT IN
THE NORTHWESTERLY FLOW TO SUPPORT A SLIGHT CHANCE OF
PRECIPITATION OVER HIGHER TERRAIN THROUGHOUT THE PERIOD; WHERE
OROGRAPHIC LIFT WILL BE THE PRIMARY DRIVER OF ANY PRECIPITATION.
SUNDAY WILL BE THE WARMEST DAY AS A RESULT OF THE RIDGING, WITH
TEMPERATURES 5-10 DEGREES ABOVE NORMAL. THE RIDGING OVER OUR
AREA WILL FLATTEN MONDAY AS THE POLAR JET STREAM DIPS SOUTHWARD
WITH AN EMBEDDED SHORTWAVE. WHILE DETAILS ARE STILL FUZZY AT 7
DAYS OUT, THIS FEATURE WILL RESULT IN A 30-50% CHANCE OF
PRECIPITATION ACROSS OUR NORTHERN ZONES.
