/ISSUED 246 PM CST FRI FEB 21 2020/  
 
SHORT TERM (TONIGHT THROUGH SATURDAY NIGHT)...  
WITH A SURFACE HIGH IN PLACE, AND CONTINUED NORTHERLY WINDS, DRIER  
AIR TONIGHT WILL RESULT IN LOW TEMPERATURES IN THE MID 30S FOR MOST  
OF THE AREA. AS THE SURFACE HIGH SHIFTS EAST, WINDS BECOME MORE  
EASTERLY, THEN RETURNING TO SOUTHEASTERLY BY SATURDAY NIGHT. THE  
HIGH FOR SATURDAY WILL STILL BE BELOW NORMAL AND IN THE UPPER 50S TO  
LOW 60S. THE SOUTHEASTERLY WINDS WILL BRING IN WARMER AND MORE MOIST  
AIR TO THE REGION, AS KEEP OVERNIGHT LOW TEMPERATURES MILD AND IN  
THE UPPER 40S TO LOW 50S. NO PRECIPITATION IS EXPECTED IN THE SHORT  
TERM.  
 
LONG TERM (SUNDAY THROUGH FRIDAY)...  
A SOUTHERLY, LOW-LEVEL WARM AIR ADVECTION PATTERN WILL SET UP  
SUNDAY IN RESPONSE TO A SOUTHERN STREAM UPPER LEVEL MOVING OUT OF  
THE SOUTHERN ROCKIES AND INTO THE TEXAS AND OKLAHOMA PANHANDLES. THIS  
WILL LEAD TO LOW CLOUDS AND PATCHY FOG IN THE MORNING. ALTHOUGH NOT  
EXPLICITLY INDICATED IN THE OFFICIAL FORECAST, THE MOISTURE DEPTH  
MAY BE JUST ENOUGH TO GENERATE ISOLATED SHOWERS BENEATH A CAPPING  
INVERSION ALONG AND EAST OF I-35 AND I-37 ON SUNDAY. WARMER ON  
SUNDAY, ESPECIALLY CLOSER TO THE RIO GRANDE WHERE AFTERNOON CLEARING  
WILL HELP TEMPERATURES TO CLIMB INTO THE MID AND UPPER 70S. ELSEWHERE  
CLOUD COVER WILL KEEP HIGH TEMPERATURES IN THE MID TO UPPER 60S.  
 
THE MAIN FORCING WITH THE AFOREMENTIONED UPPER LEVEL LOW WILL PASS  
WELL NORTH OF THE REGION. THE TAIL END OF A COLD FRONT IS FORECAST  
TO MOVE THROUGH THE REGION MONDAY MORNING. LACK OF DEEP MOISTURE AND  
FORCING WILL LIMIT CHANCES FOR ISOLATED SHOWERS TO 20% FOR ONLY  
SOUTHEASTERN AREAS. CLEARING, NORTHWEST FLOW, AND THE DRY, PACIFIC  
NATURE OF THE FRONT WILL RESULT IN EVEN WARMER AFTERNOON HIGH  
TEMPERATURES FOR MOST LOCATIONS MONDAY AFTERNOON.  
 
MODELS ARE IN GOOD AGREEMENT WITH A NORTHERN STREAM TROUGH DEEPENING  
THROUGH THE CENTRAL CONUS MONDAY NIGHT THROUGH TUESDAY. THIS WILL  
SEND A STRONGER FRONT THROUGH THE REGION TUESDAY AFTERNOON. BREEZY  
AND COLDER CONDITIONS ARE FORECAST BEHIND THE FRONT TUESDAY NIGHT  
INTO WEDNESDAY, WITH LOWS IN THE 30S AND HIGHS IN THE 50S TO AROUND  
60. A HARD FREEZE IS POSSIBLE ACROSS THE HILL COUNTRY WEDNESDAY NIGHT  
INTO THURSDAY MORNING UNDER CLEAR SKIES AND LIGHT WINDS. A LIGHT  
FREEZE OR NEAR-FREEZING CONDITIONS ARE POSSIBLE ALONG AND EAST OF  
PORTIONS OF THE I-35 CORRIDOR. A RETURN OF SOUTHERLY FLOW AND WARMING  
TREND IS FORECAST THURSDAY AND FRIDAY.
