.PREV DISCUSSION... /ISSUED 0232 AM CDT SAT MAY 30 2015/

...SYNOPSIS...
ZONAL FLOW ALOFT WILL PERSIST OVER THE NRN CONUS...WITH THE
STRONGEST WINDS RELEGATED TO NEAR THE INTERNATIONAL BORDER AND
POINTS NORTH...IN ASSOCIATION WITH A PAIR OF SHARP IMPULSES OVER THE
CANADIAN PROVINCES. THE SWRN CONUS WILL FEATURE RISING HEIGHTS AND
WARMING TEMPS ALOFT AS A RIDGE BUILDS OVERHEAD. MEANWHILE...A TROUGH
WITH SEVERAL EMBEDDED PERTURBATIONS WILL GRADUALLY PROGRESS EWD FROM
THE PLAINS STATES. AT THE SFC...HIGH PRESSURE WILL BUILD OVER
PORTIONS OF THE PLAINS/UPPER MIDWEST IN THE WAKE OF A FRONTAL SYSTEM
OVER THE MS/OH VALLEYS. TROUGHING WILL EXIST OVER MUCH OF THE
INTER-MOUNTAIN WEST...WITH A SIGNIFICANT WARMING TREND UNDERWAY.

DIURNAL MIXING WILL WORK IN CONCERT WITH A GRADUAL INCREASE IN
MID-LEVEL FLOW TO YIELD MODESTLY BREEZY CONDITIONS ACROSS PORTIONS
OF THE WRN GREAT BASIN. WITH RH VALUES FALLING BELOW 10-15 PERCENT
OVER MUCH OF THE REGION...SOME AREAS OF ELEVATED METEOROLOGICAL
CONDITIONS WILL LIKELY MATERIALIZE. HOWEVER...RAINFALL OVER THE LAST
SEVERAL WEEKS HAS INCREASED LIVE-FUEL MOISTURE AND MAINTAINED FAIRLY
LOW ERC VALUES. IN TURN...NO ELEVATED DELINEATION IS NECESSARY WITH
THE CURRENT FORECAST.
