VALID 251200Z - 261200Z  
   
..NO CRITICAL AREAS
 
 
EXAMINED NORTHWEST MINNESOTA FOR POSSIBLE ELEVATED TO NEAR CRITICAL

SNOWMELT, AND MAGNITUDE/DURATION OF WIND/RH DID NOT WARRANT  
INTRODUCTION OF AN ELEVATED AREA. THEREFORE, THERE ARE NO CHANGES TO  
THE PREVIOUS FORECAST.

/ISSUED 0118 AM CDT TUE APR 24 2018/  
   
..SYNOPSIS
 
 
A PROGRESSIVE UPPER PATTERN IS FORECAST ACROSS THE CENTRAL AND  
EASTERN CONUS ON DAY 2/WEDNESDAY. ONE UPPER TROUGH/LOW OVER THE  
CENTRAL PLAINS WEDNESDAY MORNING SHOULD CONTINUE MOVING  
SOUTHEASTWARD TO THE LOWER MS VALLEY BY THE END OF THE PERIOD.  
ANOTHER UPPER TROUGH WILL LIKELY DEVELOP SOUTHEASTWARD FROM THE  
CANADIAN PRAIRIE PROVINCES TO THE NORTHERN PLAINS. UPPER RIDGING  
SHOULD REMAIN OVER THE WESTERN CONUS. AT THE SURFACE, A COLD FRONT  
IS FORECAST TO MOVE SOUTHEASTWARD ACROSS THE NORTHERN PLAINS IN  
TANDEM WITH THE UPPER TROUGH. DRY/WARM CONDITIONS WILL PERSIST FOR  
PARTS OF THE SOUTHWEST AND GREAT BASIN WEDNESDAY AFTERNOON, BUT WEAK  
SURFACE WINDS WILL PRECLUDE ANY ELEVATED/CRITICAL CONCERNS ACROSS  
THESE AREAS.  
   
..PORTIONS OF THE NORTHERN PLAINS
 
 
THE SURFACE PRESSURE GRADIENT SHOULD STRENGTHEN SLIGHTLY AHEAD OF  
THE COLD FRONT MENTIONED PREVIOUSLY ACROSS PARTS OF THE NORTHERN  
PLAINS WEDNESDAY AFTERNOON. MODESTLY ENHANCED MID-LEVEL WINDS MAY  
ALSO SUPPORT SOME INCREASE IN SURFACE WINDS ACROSS THIS REGION. MOST  
SHORT-TERM GUIDANCE INDICATED SUSTAINED SOUTHWESTERLY WINDS OF 15-20  
MPH SHOULD OCCUR AHEAD OF THE FRONT, MAINLY ACROSS PARTS OF THE  
DAKOTAS INTO NORTHWESTERN MN. GIVEN LITTLE PROSPECT FOR SUBSTANTIAL  
LOW-LEVEL MOISTURE RETURN, RH VALUES MAY BECOME LOWERED NEAR 25% FOR  
A FEW HOURS WEDNESDAY AFTERNOON ON A BRIEF/ISOLATED BASIS. HOWEVER,  
FUELS MAY NOT BE OVERLY RECEPTIVE FOR PARTS OF THIS REGION DUE TO  
ONGOING LIGHT TO MODERATE PRECIPITATION MOVING EASTWARD ACROSS THE  
NORTHERN PLAINS ON DAY 1/TUESDAY. OVERALL, THE METEOROLOGICAL  
CONDITIONS AND FUELS APPEAR TOO BORDERLINE TO JUSTIFY THE  
INTRODUCTION OF AN ELEVATED AREA AT THIS TIME.
