AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
923 AM MDT SAT APR 18 2015

.SYNOPSIS...NORTHWESTERLY FLOW WILL PREVAIL THROUGH THE WEEKEND.
HIGH PRESSURE WILL TEMPORARILY STRENGTHEN EARLY NEXT WEEK...BEFORE
AN UNSETTLED WEATHER PATTERN DEVELOPS FOR THE LATTER PORTION OF
THE WEEK.


&&

.DISCUSSION...THE FORECAST AREA IS UNDER NORTHERLY FLOW THIS
MORNING BEHIND THE STORM SYSTEM JUST EAST OF THE FOUR CORNERS.
ASSOCIATED CLOUDS AND LIGHT SHOWERS OVER FAR EASTERN UTAH WILL
CONTINUE TO WEAKEN THIS MORNING. THE SYSTEM WILL CONTINUE TO
SLOWLY TRACK AWAY FROM THE AREA TODAY...BUT ENOUGH RESIDUAL
MOISTURE AND INSTABILITY WILL REMAIN TO ALLOW FOR A BIT OF
CONVECTION OVER THE HIGHER TERRAIN. THE WARMING TREND IN
TEMPERATURES WILL CONTINUE TODAY...WITH MAXES RUNNING ABOUT 5F
ABOVE SEASONAL NORMS ACROSS MUCH OF THE CWA.

A WEAK SHORTWAVE IS PROGGED TO MOVE ACROSS UTAH AND SOUTHWEST
WYOMING THIS EVENING AND OVERNIGHT...CURBING THE WARMING TREND A
BIT FOR TOMORROW. IT WILL ALSO KEEP SOME INSTABILITY AROUND AS THE
FOUR CORNERS SYSTEM EXITS. WEAK HIGH PRESSURE IS EXPECTED TO BUILD
FOR MONDAY AND TUESDAY...ALLOWING FOR ADDITIONAL WARMING. SOME
AFTERNOON CONVECTION IS POSSIBLE OVER THE HIGHER TERRAIN...BUT THE
THREAT IS LESS THAN WHAT IS EXPECTED DURING THE WEEKEND. BY THE
MIDDLE OF THE WEEK...THE WEATHER PATTERN BECOMES MORE UNSETTLED.
HOWEVER...MODELS ARE SHOWING WORSE THAN USUAL RUN-TO-RUN
CONSISTENCY WITH RESPECT TO THE DETAILS.

NO UPDATES EXPECTED TO THE FORECAST THIS MORNING.

&&

.AVIATION...LIGHT AND VARIABLE WINDS AT THE SLC TERMINAL WILL BECOME
PREDOMINANTLY NORTH TO NORTHWEST BETWEEN 16-18Z.

&&

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