JETLET AT 700 MB AFTER 06Z/SAT. LOCAL WIND CORRIDOR GRADIENTS ALSO
QUITE FAVORABLE FOR VERY STRONG WINDS LATE TONIGHT/SAT. 700 MB 40-60
KT JETLET CONTINUES THRU 18Z/SAT THEN WINDS DECREASE AFTER 18Z. WILL
UPGRADE THE HIGH WIND WATCH TO A HIGH WIND WARNING AND EXPAND TO WY

WILL ALSO ISSUE A WIND ADVISORY FOR SAT FOR THE WRN NEB PANHANDLE
ZONES PER LOW LEVEL GRADIENTS/WIND PROGS. THANK YOU UNR/LBF FOR
COORDINATION. WILL GO WITH ETA SOLUTION OF OROGRAPHIC SNOW SHOWERS
ACROSS CARBON CNTY/SNOWY RANGE TONIGHT...THEN SPREAD CHANCE SNOW

CLOUD COVER. THEN QUESTION GFS HANDLING OF THIS FEATURE AS IT MOVES
SOUTHEAST ACROSS WY...IT KEEPS SHORT WAVE FAIRLY STRONG AS IT MOVES
THROUGH THE RIDGE AXIS. WILL CONTINUE DRY FORECAST AS THIS SOLUTION
LOOKS UNLIKELY AND STAY IN LINE WITH SURROUNDING OFFICES. GENERALLY
EXPECT RIDGE AXIS TO HOLD OVER THE AREA THRU THE END OF THE
