DISCUSSION
 
HIGH PRESSURE REMAINS THE DOMINANT FEATURE OVER THE  
NORTHERN ROCKIES FOR THE NEXT SEVERAL DAYS WITH WARM AND DRY  
CONDITIONS. TODAY TEMPERATURES SHOULD WARM TO BE SLIGHTLY ABOVE  
SEASON NORMALS. THESE WARM TEMPERATURES HAVE ALLOWED THE SNOW TO  
STEADILY MELT THROUGHOUT THE LOWER ELEVATIONS OF THE NORTHERN  
ROCKIES. THANKFULLY THE OVERNIGHT TEMPERATURES HAVE BEEN DROPPING  
BELOW FREEZING SO FLOODING HAS NOT BECOME AN ISSUE.  
 
A LOW PRESSURE SYSTEM IS STILL ANTICIPATED TO UNDERCUT THE RIDGE  
BY THE LATTER PART OF THE WORK WEEK. THIS DISTURBANCE WILL  
INCREASE CLOUD COVER OVER THE LEMHI COUNTY INTO SOUTHWEST MONTANA  
ON THURSDAY AND FRIDAY. THE MODELS ARE STILL DEPICTING AN ACTIVE  
WEATHER PATTERN FOR THE WEEKEND AS SHOWERS BECOME PREVALENT. THE  
AMOUNT OF MOISTURE ASSOCIATED WITH THE SHOWER ACTIVITY IS STILL  
UNCERTAIN.  
 

 
   
AVIATION
 
VFR CONDITIONS WILL CONTINUE ACROSS WESTERN MONTANA  
AND CENTRAL IDAHO WITH GENERALLY CLEAR SKIES AND LIGHT WINDS.  
PATCHY FOG WILL BE POSSIBLE ONCE AGAIN TUESDAY MORNING, PRIMARILY  
ACROSS NORTHWEST MONTANA AND IN THE VICINITY OF KGPI.
