/ISSUED 0257 AM CDT SAT MAR 28 2020/  
   
..SYNOPSIS
 
 
A DEEP MID/UPPER-LEVEL TROUGH AND ATTENDANT SURFACE LOW ARE FORECAST  
TO MOVE FROM THE CENTRAL PLAINS INTO PORTIONS OF THE UPPER MIDWEST  
TODAY. A PACIFIC COLD FRONT WILL SWEEP THROUGH THE REMAINDER OF THE  
SOUTHERN PLAINS DURING THE MORNING/EARLY AFTERNOON. RELATIVELY  
DRY/BREEZY CONDITIONS WILL BRING ANOTHER DAY OF ELEVATED TO  
POTENTIALLY CRITICAL FIRE-WEATHER CONDITIONS ACROSS PORTIONS OF THE  
SOUTHERN HIGH PLAINS, POTENTIALLY EXTENDING INTO PORTIONS OF SOUTH  
TX ALONG THE RIO GRANDE.  
   
..SOUTHERN HIGH PLAINS INTO PORTIONS OF SOUTH TX
 
 
IN THE WAKE OF THE PACIFIC COLD FRONT, DRY WESTERLY FLOW WILL SPREAD  
ACROSS MUCH OF THE SOUTHERN HIGH PLAINS INTO PORTIONS OF SOUTH TX.  
SUSTAINED WINDS OF 20-25 MPH COMBINED WITH MINIMUM RH VALUES OF  
10-20% WILL SUPPORT NEAR-CRITICAL METEOROLOGICAL CONDITIONS ACROSS  
EAST-CENTRAL NM INTO ADJACENT PORTIONS OF WEST TX. HOWEVER, WITH  
RELATIVELY BENIGN FUEL CONDITIONS AND GENERALLY BELOW-AVERAGE  
TEMPERATURES EXPECTED, HAVE OPTED TO DOWNGRADE TO ELEVATED IN THIS  
AREA.  
 
CRITICAL WIND/RH CONDITIONS, WITH MUCH WARMER SURFACE TEMPERATURES,  
WILL SPREAD INTO PORTIONS OF THE MIDDLE/LOWER RIO GRANDE VALLEY THIS  
AFTERNOON, WHERE A CRITICAL AREA HAS BEEN ADDED WITH THIS OUTLOOK.  
 
A LARGE AREA OF ELEVATED TO LOCALLY CRITICAL CONDITIONS WILL  
ENCOMPASS A LARGER PORTION OF THE SOUTHERN HIGH PLAINS. THE EASTWARD  
EXTENT OF ELEVATED CONDITIONS REMAINS CONSTRAINED BY RECENT RAINFALL  
AND ONGOING GREENUP, THOUGH RELATIVELY DRY/BREEZY CONDITIONS WILL  
LIKELY SPREAD AS FAR AS EASTERN OK/NORTHEAST TX BY AFTERNOON.
