WIDESPREAD SHOWERS CONTINUE ACROSS MUCH OF THE
AREA THIS MORNING AS A WEAK COLD FRONT PUSHES SLOWLY SOUTH AND
EAST. SNOW LEVELS HAVE DROPPED TO AROUND 4500 TO 5500 FEET MSL
BEHIND THE FRONT, BUT PRECIPITATION HAS ENDED POST FRONTAL
PASSAGE. DRIER AIR WILL MOVE INTO THE REGION THIS AFTERNOON AS A
TRANSIENT UPPER LEVEL RIDGE BEGINS TO BUILD FROM THE WEST. THIS

SOUTHWEST IDAHO BY THIS EVENING. BREEZY CONDITIONS EXPECTED
ACROSS SOUTH-CENTRAL IDAHO WITH THE STRONGEST WINDS, GUSTS UP TO
40 MPH, IN THE CAMAS PRAIRIE AND WESTERN MAGIC VALLEY. PATCHY
FOG IS EXPECTED TO DEVELOP IN THE VALLEYS EARLY THURSDAY MORNING
GIVEN THE RECENT MOISTURE AND CLEARING SKIES. TEMPERATURES
TODAY WILL BE COOLER THAN TUESDAY, RETURNING CLOSER TO SEASONAL
NORMALS. NO UPDATES NEEDED AT THIS TIME.
