UPPER TROF DIGGING INTO CENTRAL CALIFORNIA WITH CORRESPONDING
BUILDING OF THE UPPER RIDGE OVER WYOMING.  THIS WELL-EVIDENCED ON
WATER VAPOR IMAGERY WHERE DEEP MOISTURE PLUME ASSOCIATED WITH STRONG
ELONGATED SHORTWAVE IS BEING PUSHED BACK NORTH AND WEST.  THIS RIDGE
BUILDING ALLOWING THE PERIPHERY OF MONSOONAL MOISTURE TO INCH CLOSER
TO SWEETWATER COUNTY.  COULD PERHAPS SEE A STRAY SHOWER OR STORM
CREEP INTO THE SOUTH THIS EVENING...BUT CANNOT FIND MUCH IN THE WAY
OF LIFT TO ENHANCE THE DEEPER MOISTURE COMING UP TO PRODUCE THAT
WOULD BE SIGNIFICANT.  MORNING MODELS IN DECENT AGREEMENT AS TO
EVOLUTION OF THINGS NEXT 24 HOURS OR SO.  TROF EXPECTED TO BUMP INTO
THE RIDGE AND WEAKEN IT SLIGHTLY WHILE RIDING UP AND OVER ACROSS
MONTANA TONIGHT AND TOMORROW.  MEANWHILE A SURFACE FRONT IS DRIVEN
ACROSS THE NORTHERN PART OF THE AREA TONIGHT.  JET CROSSES THE WEST
AND NORTH BEGINNING LATER TONIGHT AND CONTINUING THRU TOMORROW.
HOWEVER...BEST DYNAMICS WITH JET REMAIN OVER MONTANA WHERE THE 500
COLD POOL CROSSES...AS DOES THE LIONS SHARE OF THE MOISTURE.  WHAT
DYNAMICS THE JET DOES PROVIDE FARTHER SOUTH IN THE RRQ GETS WASTED
IN DRY AIR.  WIND BEHIND FRONT SHIFTS TO NORTH NORTHEAST LATER THIS
EVENING AND TONIGHT...BUT QUICKLY BACKS TO WEST AGAIN TOMORROW AS
SURFACE HIGH COMES IN FROM THE WEST AND GRADIENT TIGHTENS
SUBSTANTIALLY.  SO PERHAPS SOME SHOWERS OR THUNDERSTORMS FOR THE
NORTHWEST AND NORTH TONIGHT...AND THAT APPEARS TO BE ABOUT IT.  SOME
HELP FOR THE NORTHWEST FIRES PERHAPS...BUT WITH FLOW QUICKLY BACKING
TO WEST TOMORROW THE INCREASED DEWPOINTS OF TONIGHT WILL DROP
QUICKLY AND WIND WILL PICK UP AGAIN.  THEN APPEARS WE GO BACK TO A MAINLY
DRY SCENARIO LIKE WE JUST HAD UNTIL THE WEEKEND...WHEN MODELS
INDICATING ANOTHER POTENTIAL TROF PASSAGE AND MAYBE SOME MONSOONAL
MOISTURE.  WILL DO VERY LITTLE FOR EXTENDED AS IT SEEMS TO BE IN
DECENT SHAPE WITH MAINLY DRY CONDITIONS EXPECTED EXCEPT FOR MAYBE
FRIDAY AND SATURDAY WHEN SOME MOISTURE COULD GET IN.
