AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
931 AM MDT FRI JUL 19 2013

.SYNOPSIS...LIGHT NORTHERLY FLOW WILL ALLOW FOR THE DRYING TREND
FROM NORTH TO SOUTH TO CONTINUE THROUGH SATURDAY...WITH MOISTURE
BECOMING INCREASINGLY CONFINED TO FAR SOUTHERN UTAH OVER THE
WEEKEND. HIGH PRESSURE WILL STRENGTHEN OVER NEVADA KEEPING
TEMPERATURES WELL ABOVE NORMAL.

&&

.DISCUSSION...MODELS AND SATELLITE SHOW THE MID LEVEL RIDGE AXIS
HAS SHIFTED WESTWARD INTO NEVADA WHERE IT WILL REMAIN FOR THE NEXT
FEW DAYS. A LIGHT NORTH TO NORTHEAST FLOW ALOFT AROUND THE HIGH
WILL REMAIN ACROSS THE FORECAST AREA. THIS FLOW IS PULLING DRIER
AIR INTO NORTHERN UTAH...WHERE GOES PRECIPITABLE WATER HAS FALLEN
BELOW 0.5 INCHES NORTH OF I-80. COPIOUS MOISTURE REMAINS ACROSS
CENTRAL AND SOUTHERN UTAH.

DRIER AIR WILL CONTINUE TO WORK ITS WAY SOUTHWARD INTO CENTRAL
UTAH TODAY...WHILE MOISTURE REMAINS IN PLACE ACROSS THE SOUTH.
AS A RESULT EXPECT ANOTHER ACTIVE DAY ACROSS THE SOUTH WITH
LOCALLY HEAVY RAINFALL POSSIBLE UNDER WIDELY SCATTERED SHOWERS
AND THUNDERSTORMS. LIKE YESTERDAY...THE NORTHERLY COMPONENT TO THE
FLOW WILL PUSH CONVECTION SOUTHWARD OFF THE HIGHER TERRAIN BY
AFTERNOON. RESULTANT DOWNBASIN PROPAGATION WILL ENHANCE THE
POTENTIAL FOR LOCALIZED FLASH FLOODING OVER SOUTHERN UTAH
ESPECIALLY OVER FLOOD PRONE BASINS. BURN SCARS OVER CENTRAL AND
SOUTHERN UTAH ALSO NEED CLOSE SCRUTINY FOR POTENTIAL HEAVY RAIN.

&&

.AVIATION...THE SLC TERMINAL WILL SEE VFR CONDITIONS THROUGHOUT THE
DAY AND INTO THIS EVENING WITH MOSTLY CLEAR SKIES. SOUTHEAST
WINDS ARE EXPECTED TO SHIFT TO THE NORTHWEST BETWEEN 17Z AND 19Z.
NORMAL RETURN TO SOUTHEAST WINDS EXPECTED BETWEEN 03-04Z.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...NONE.
WY...NONE.

PUBLIC/AVIATION...YOUNG
