.SYNOPSIS...A WEAK WEATHER SYSTEM WILL MOVE SOUTHEAST ACROSS THE
REGION TODAY...FOLLOWED BY HIGH PRESSURE FOR THURSDAY. THE NEXT
WEAKENING STORM SYSTEM WILL CROSS THE REGION FRIDAY THROUGH
SATURDAY.

&&

.DISCUSSION...THE SURFACE COLD FRONT THAT MOVED THROUGH THE AREA
OVERNIGHT HAS NOW PUSHED INTO THE FOUR CORNERS REGION LEAVING
NORTHWEST FLOW IN ITS WAKE. GUSTY POST FRONTAL WINDS OVER THE
HIGHER TERRAIN OF THE SOUTH HAS SHOWN SIGNS OF DECREASING AND
THESE TRENDS ARE EXPECTED TO CONTINUE THROUGH THE DAY. MID AND
HIGH LEVEL CLOUDS CONTINUE TO INCREASE FROM WEST TO EAST
ASSOCIATED WITH A WEAK TRAILING WAVE OVER EASTERN NEVADA THIS
MORNING...AND HAVE INCREASED CLOUD COVERAGE AS THE ONLY NOTABLE
UPDATE TO THE FORECAST. ALTHOUGH A FEW SHOWERS REMAIN POSSIBLE
OVER THE HIGHER TERRAIN TODAY...PASSAGE OF THIS WEAK SYSTEM WILL
BRING MINIMAL CHANGES TO SENSIBLE WEATHER.

MID LEVEL RIDGING OVER THE EASTERN PACIFIC WILL SHIFT INLAND
TONIGHT THROUGH TOMORROW ALLOWING H7 TEMPS TO WARM SOME 4 TO 6
DEGREES C OVER THE NEXT 24 HOURS. EXPECTING SOME 10 DEGREES F
WARMING AT THE SURFACE FOR THURSDAY WITH ANY LINGERING CLOUD COVER
THINNING DURING THE AFTERNOON HOURS.

THE PRIMARY FORECAST CHALLENGE FOR THE DAY WILL FOCUS ON THE
TROUGH CURRENTLY ORIENTED AROUND 150W. NOT EXPECTING SIGNIFICANT
IMPACT TO THE FORECAST AREA AS THIS TROUGH SPLITS AND MOVES ON
SHORE DURING THE FRIDAY/SATURDAY PERIOD...BUT SOME SHOWER ACTIVITY
DOES LOOK TO DEVELOP AREAWIDE AS THE SOUTHERN SPLIT TRACKS THROUGH
THE DESERT SOUTHWEST AND THE NORTHERN DRAGS THEN STALLS A WEAK
FRONTAL BOUNDARY ACROSS THE NORTH.

LONG TERM WILL BE FOCUSING ON THE POTENTIAL OF A MUCH STRONGER
TROUGH FOR EARLY NEXT WEEK...BUT AS NOTED IN THE LAST PACKAGE
INCONSISTENCIES IN STRENGTH AND EVOLUTION OF THIS SYSTEM REMAIN
AND WILL LIKELY CONTINUE FOR SEVERAL RUNS.

&&

.AVIATION...WINDS AT THE SLC TERMINAL WILL REMAIN FROM THE NORTH
THROUGH THE DAY. WIND SPEED WILL INCREASE INTO THIS AFTERNOON...WITH
SPEEDS ABOVE 7 KNOTS BY 16Z TO 17Z. VFR CONDITIONS WILL PREVAIL.
