AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
941 PM MDT THU OCT 23 2014

.SYNOPSIS...A WARM DRY SOUTHWEST FLOW OVER THE AREA WILL BECOME
STRONGER ON SATURDAY. A STRONG COLD FRONT WILL CROSS UTAH ON
SUNDAY.

&&

.DISCUSSION...THE AXIS OF THE HIGH OVER THE REGION IS ALONG THE
ERN UT BORDER WITH A MILD SWLY FLOW OVER THE CWA. CONSIDERABLE
HIGH CLOUDINESS HAS BEEN STREAMING THROUGH THE STATE WITH THE
THICKEST CLOUDS ACROSS THE NORTHWEST THIS EVENING.

THE RIDGE IS FORECAST TO AMPLIFY OVER THE NEXT 24 HOURS. THE
RISING HEIGHTS AND BACKING FLOW WILL SHUNT THE JETSTREAM AND
ASSOCIATED CIRRUS PLUME OFF TO THE NORTH OF THE CWA BY TOMORROW
MORNING WITH A SUNNY WARM DAY EXPECTED.

SOUTH WINDS WILL BE A LITTLE STRONGER TOMORROW AND SHOULD PROVIDE
GOOD MIXING ALLOWING TEMPS TO RISE SEVERAL DEGREES FROM TODAY.

THE LARGE TROF IN THE ERN PAC STARTS TO NOSE INLAND SAT AND THE
INCREASING FLOW ALOFT PLUS A TIGHTENING SURFACE GRADIENT SHOULD
BOOST WINDS CONSIDERABLY. TEMPS WILL STAY WARM AND MAY EVEN RISE
A LITTLE FROM FRIDAY IN THE SALT LAKE AREA.

THE NEW 00Z NAM HAS THE COLD FRONT ARRIVING IN TWO PARTS WITH AN
INITIAL PUSH BEFORE SUNRISE SUNDAY AND THE MAIN COLD PUSH SUNDAY
AFTN. IT GENERATES SOME PRECIP ACROSS THE NORTH WITH BOTH
BOUNDARIES BUT IT IS NOT GENEROUS WITH THE QPF. AT THIS TIME IT
APPEARS THE MAIN IMPACT FROM THIS SYSTEM WILL BE STRONG PRE AND
POST FRONTAL WINDS AND SIGNIFICANTLY COOLER TEMPS...WITH JUST A
FEW POCKETS OF SIGNIFICANT SNOWFALL IN THE NRN MTNS.

UPDATED EARLIER TO INCREASE SKY COVER ACROSS MUCH OF THE CWA FOR
THE FIRST PART OF THE NIGHT AND TO DECREASE IT AFTER MIDNIGHT. NO
ADDITIONAL UPDATES PLANNED.

&&

.AVIATION...WINDS AT THE SLC TERMINAL WILL BE SOUTHEASTERLY
THROUGH THE NIGHT. WINDS WILL BECOME GUSTY OUT OF THE SOUTH BY
LATE MORNING FRIDAY.

&&

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