AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
647 PM MDT THU MAY 28 2015

.SYNOPSIS...AN UPPER LOW OVER THE NORTHERN ROCKIES WILL MOVE EAST
INTO THE PLAINS STATES TOMORROW. HIGH PRESSURE WILL STRENGTHEN
ACROSS THE REGION THIS WEEKEND...RESULTING IN A SUBSTANTIAL
WARMING AND DRYING TREND.


&&

.SHORT TERM...HAVE UPDATED THE FORECAST FOR THIS EVENING AS
SHOWERS AND THUNDERSTORMS HAVE DIMINISHED RAPIDLY LATE THIS
AFTERNOON AND EARLY EVENING ACROSS THE NORTH. THIS DUE TO LOWER
SUN ANGLE AND THE COLD POOL ALOFT MOVING EAST RESULTING IN AN AIR
MASS THAT IS QUICKLY STABILIZING. THE SOUTHERN AND CENTRAL PORTIONOF
THE CWA WILL STILL HAVE ISOLATED TO SCATTERED MOUNTAIN SHOWERS AND
THUNDERSTORMS FOR A COUPLE OF MORE HOURS AS THEY ARE BEING DRIVEN
BUT THE REMNANTS OF A MID LEVEL BOUNDARY THAT MOVED ACROSS
NORTHERN UTAH EARLIER IN THE DAY AND NOW IS REACHING THE CENTRAL
REGION OF THE STATE. THESE WILL DIE OFF THIS EVENING AND THEREFORE
HAVE REMOVED ALL CHANCES OF SHOWERS AND THUNDERSTORMS FOR THE
LATER HALF OF THE NIGHT.

SKIES HAVE ALSO CLEARED OFF ACROSS THE NORTHWEST PORTION OF UTAH
AND DISSIPATED SUBSTANTIALLY OVER THE REST OF NORTHERN UTAH AND
SOUTHWEST WYOMING IN PAST HOUR.


&&

.AVIATION...WINDS SHOULD REMAIN OUT OF THE NORTHWEST AT THE SLC
TERMINAL THROUGH AT LEAST 03Z...WITH A 40 PERCENT CHANCE OF
REMAINING NORTH THROUGH 05Z. NO OTHER WEATHER CONCERNS FOR THE SLC
TERMINAL TONIGHT.

&&

.FIRE WEATHER...FAIRLY SIMILAR TEMPERATURE/HUMIDITY FOR THE
REST OF TODAY COMPARED TO YESTERDAY. IT IS ONCE AGAIN SOMEWHAT
COOL/MOIST ACROSS THE NORTH...AND DRY AND WARM ACROSS THE SOUTH.
AFTERNOON AND EVENING THUNDERSTORMS HOWEVER SHOULD CONTINUE TO BE
MORE EVENLY DISTRIBUTED ACROSS THE STATE. THE STRONGEST ACTIVITY
WILL BRING A CHANCE FOR CLOUD TO GROUND LIGHTNING...BRIEF HEAVY
RAIN...SMALL HAIL...AND GUSTY/ERRATIC WINDS.

THE PATTERN SHIFTS TOMORROW THROUGH THE WEEKEND AS A RIDGE BUILDS
IN. EXPECT VERY WARM CONDITIONS AND A DRYING TREND ACROSS ALL OF
UTAH. THE CHANCE FOR AFTERNOON SHOWERS AND THUNDERSTORMS WILL THIN
EACH DAY AND BE RELEGATED TO THE MOUNTAINS FOR THE MOST PART.
SOUTHERLY WINDS WILL BECOME GUSTY SUNDAY...INCREASING THROUGH
TUESDAY...WITH A STRONG LIKELIHOOD OF SEEING CRITICAL METEOROLOGICAL
FIRE WEATHER CONDITIONS SUNDAY INTO EARLY NEXT WEEK.

COOLING AND MOISTENING CONDITIONS DEVELOP ACROSS THE NORTH BY MID
WEEK BEHIND THE NEXT COOL FRONT. SHOWERS SHOULD INCREASE IN COVERAGE
AGAIN YET SHOULD NOT BE AS WIDESPREAD AS THE LAST COUPLE OF WEEKS.

&&

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