SUNDAY WITH VERY GOOD AGREEMENT ON TIMING BETWEEN THE NAM/GFS...
ALTHOUGH THE GFS IS SLIGHTLY STRONGER. THIS SYSTEM TO PRODUCE A WIDE
VARIETY OF WEATHER ACROSS THE CWA AS IT SHIFTS ACROSS. SNOW TO BEGIN
OVER THE SOUTHERN SIERRA SATURDAY AFTERNOON WITH LOCALLY HEAVY SNOW
SATURDAY NIGHT INTO SUNDAY WITH LOCALLY HEAVY SNOW POSSIBLE OVER THE
SOUTHERN NEVADA MOUNTAINS MAINLY ON SUNDAY...BUT FOR NOW AMOUNTS

ASSOCIATED ENERGY/DYNAMICS WILL BE NORTHEAST OF THE AREA. IT WILL
DRAG A WEAK FRONT THROUGH THE AREA EARLY TUESDAY MORNING AND AS IS
USUAL IN THIS SITUATION THE PRESSURE GRADIENT BEHIND IT STRENGTHENS
IN SOUTHERN NEVADA SETTING UP THE POTENTIAL FOR BREEZY OR GREATER
WINDS DOWN THE COLORADO RIVER VALLEY. ASIDE FROM THIS THE NEXT
SYSTEM LOOKS TO BE THURSDAY WITH SOME MODEL DISAGREEMENT ON ITS
TRACK. GFS BRINGS IN IN SIMILAR TO TUESDAYS WHILE ECMWF BRINGS IT
DOWN THE COAST. OF GFS PROVES RIGHT WE COULD AGAIN HAVE BREEZY WINDS
THURSDAY. FOR NOW HAVE LEFT IT DRY AND NO WINDS THEN. TEMPERATURES
