LATE EVENING SATELLITE IMAGERY DEPICTS SHORTWAVE TROUGH PROGRESSING
STEADILY SEWD ACROSS NRN CA INTO THE GREAT BASIN AS STRONGER HIGH
LEVEL FLOW DEVELOPS TOWARD NRN AZ.  PLUME OF STEEP MID LEVEL LAPSE
RATES NORTH OF THIS JET WILL SPREAD ACROSS THE 4-CORNERS REGION
LATER TODAY ENHANCING THE THREAT FOR CONVECTION.  FORECAST SOUNDINGS
SUGGEST MUCH OF THIS CONVECTION WILL FALL AS HEAVY SNOW SHOWERS AT
HIGH ELEVATIONS WITH JUST ENOUGH INSTABILITY PRESENT FOR ISOLATED
LIGHTNING.  THIS SHOULD BE STRONGLY DIURNAL IN NATURE WITH LITTLE
CHANCE FOR TSTM ACTIVITY TO SPREAD EAST OF THE ROCKIES.

ANOTHER IN A SERIES OF SHORTWAVE TROUGHS WILL APPROACH THE WA COAST
LATE IN THE PERIOD. THIS FEATURE WILL FORCE A COLD FRONT ONSHORE
AFTER 06Z ALONG WITH COOLING PROFILES AND INCREASED PROBABILITIES
FOR LOW TOPPED CONVECTION.  EVEN SO...FORECAST SOUNDINGS SUGGEST ANY
MEANINGFUL THREAT FOR LIGHTING WILL HOLD OFFSHORE DURING THE PERIOD
DUE TO WEAK INSTABILITY.
