.SYNOPSIS...AN UPPER LEVEL WEATHER DISTURBANCE OVER EASTERN NEVADA

AROUND A COMMON CENTER OVER CNTRL ID/SWRN MT.  THE NEXT VORTICITY
MAX TO AFFECT NRN UT CURRENTLY OVER E/CNTRL NV...AND LIFTING NE AT
TIME. CONVECTION HAS DEVELOPED OUT AHEAD OF THIS FEATURE OVER NW UT
ALONG AND JUST AHEAD OF THE 700 MB THERMAL BOUNDARY NEAR THE UT/NV
BORDER. EXPECTING THE VORTICITY MAX AND THE ASSOCIATED COLD FRONT
ALOFT TO RIP THROUGH NRN UT THIS MORNING/EARLY AFTERNOON.
RAINFALL AMOUNTS ARE NOT EXPECTED TO BE QUITE AS MUCH AS YESTERDAY...
WITH THE HEAVIEST AMOUNTS CONFINED TO THE FAR NORTH WHERE DYNAMICS
AND DEEP LAYER COLD ADVECTION ARE THE STRONGEST.

SUBSIDENCE SHOULD KEEP SHOWERS TO A MINIMUM THIS EVENING. THE NEXT
SHORTWAVE TO AFFECT NRN UT SCHEDULED TO ARRIVE WEDNESDAY.
CONVERGENCE ALONG THE 700MB THERMAL BOUNDARY COULD LEAD TO SOME
LIGHT SHOWERS UP NORTH LATE WEDNESDAY NIGHT...WITH THE BEST THREAT
ASSOCIATED WITH THE SHORTWAVE DURING THE DAY WEDNESDAY.  THE 06Z
NAM MODEL NOT QUITE AS STRONG OR AS FAR SOUTH AS PREVIOUS RUNS.  IF
THIS TREND HOLDS IN SUBSEQUENT MODEL RUNS...THEN THE THREAT OF
PRECIP WILL HAVE TO BE REDUCED AND PUSHED FURTHER NORTH THAN IN THE
CURRENT FORECAST.

CYCLONIC LOW-AMPLITUDE WESTERLIES ACROSS THE NRN HALF OF THE WRN
REGION LOOK TO DOMINATE THROUGH THE COMING WEEKEND.  CONFIDENCE IN
THE GFS AND ITS HANDLING OF THE DETAILS NOT ALL THAT HIGH AS OF
LATE.  FOR NOW THE BEST PATH TO FOLLOW WILL BE TO MENTION A THREAT
OF PRECIP IN THE MOUNTAINS AND FAR NORTH...BUT NOT EXPECT ANYTHING
THAT SUBSTANTIAL DURING THE EXTENDED PERIOD AS MOST OF THE ENERGY
WILL PROBABLY STAY TO OUR NORTH. TEMPS WILL REBOUND...BUT ONLY TO
READINGS CLOSE TO OR SLIGHTLY BELOW NORMAL FOR THE SECOND WEEK OF
