AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
858 PM MDT WED JUL 30 2014

.SYNOPSIS...HIGH PRESSURE WILL REMAIN IN PLACE ACROSS THE
REGION INTO EARLY NEXT WEEK. A WEAK DISTURBANCE WILL MOVE THROUGH
THE HIGH LATE THURSDAY THROUGH FRIDAY. THEN THE RIDGE WILL
STRENGTHEN OVER THE WEEKEND. A STRONGER DISTURBANCE WILL LIFT
THROUGH THE AREA SUNDAY NIGHT AND MONDAY.

&&

.DISCUSSION...A RIDGE HAS SET UP TO OUR WEST THIS EVE WITH A
CYCLONICALLY CURVED NORTH TO NORTHWEST FLOW OVER THE CWA AROUND
THE SHEARED REMAINS OF THE TROF AXIS THAT SITS E-W ALONG THE UINTA
MTNS.

CONVECTION ASSOCIATED WITH THE TROF AXIS HAS JUST ABOUT MOVED OUT
OF THE CWA ALTHO LIGHT OROGRAPHIC PRECIP IS LIKELY PERSISTING
UNDER THE THICK LOWER CLOUDS ACROSS SWRN WY AND OVER THE UINTAS.

MEANWHILE THE THE WEAK TROF THAT IS LIFTING INTO THE GREAT BASIN
FROM CA HAS SET UP A WEAK CONVERGENCE DOWNSTREAM ACROSS SRN NV
INTO SRN UT AND CONVECTION FIRED IN THIS AREA LATE IN THE DAY.
THIS CONTINUES AT THIS TIME WITH SOME PERSISTENT CELLS FORMING
OVER AND NEAR CAPITOL REEF NP AND OTHERS WWD ACROSS KANE CO AND W
OF MILFORD ALONG THE NV BORDER. HAVE SOME CONCERN THAT HEAVY
RUNOFF FROM THE CAPITOL REEF STORMS COULD BE RUNNING THRU THE
WASHES IN THAT AREA BUT DONT THINK IT WILL RESULT IN SIGNIFICANT
FLOODING.

LATEST MODELS KEEP CONVECTION ACTIVE ACROSS SWRN OVERNIGHT INTO
THU THEN LIFT IT NWD THU AFTN AS THE CA TROF CONTINUES TO LIFT
INTO THE GREAT BASIN. THIS FEATURE THEN MERGES WITH THE REMNANT
TROF AXIS ACROSS NRN UT AND SLIDES E THU NIGHT THRU FRI.

UPDATED FORECASTS EARLIER TO ADD POPS TO THE FAR SOUTH FOR THE
EVE. UPDATED AGAIN TO KEEP POPS ACROSS SWRN THRU THE NIGHT. NO
ADDITIONAL UPDATES PLANNED.
