230 AM MDT SUN OCT 4 1998

INVERTED SURFACE TROUGH AND A VERY MOIST AIRMASS REMAIN OVER NORTHEAST 
MONTANA WITH LIGHT RAIN OBSERVED AT MOST LOCATIONS. MOISTURE WILL 
CONTINUE TO STREAM NORTH AND WRAP AROUND THE LOW THAT DEEPENS OVER THE 
CENTRAL HIGH PLAINS TODAY AND TONIGHT. THIS WILL KEEP NORTHEAST MONTANA 
IN THE MOIST AIRMASS WITH SOME DRYING NOTED FROM WEST ON MONDAY AS 
SURFACE HIGH PRESSURE AND A RIDGE ALOFT TRY TO PUSH INTO THE STATE.
00Z NGM AND ETA HANDLE THE LOW THAT DEEPENS OVER THE PLAINS A LITTLE 
DIFFERENTLY. THE NGM STACKS THE LOW OVER THE NEBRASKA/SOUTH DAKOTA 
BORDER. THE ETA KEEPS THE UPPER LOW CENTER AHEAD OF THE SURFACE 
LOW...LIFTING THE SYSTEM FURTHER TO THE NORTHEAST ON MONDAY FOR A 
BETTER CHANCE OF NORTHEAST MONTANA CLEARING OUT SOMEWHAT. WILL GO 
CLOSER TO ETA SOLUTION OF MOVING PLAINS LOW FURTHER NORTHEAST AND 
SCATTERING OUT WESTERN PORTIONS OF FORECAST AREA ON MONDAY. FAR EASTERN 
SECTIONS WILL STAY UNDER RAIN TODAY...WITH LIKELY POPS THROUGH MONDAY. 
TEMPS WILL CHANGE LITTLE. LOCKHART
