SHORT TERM
 
(THIS EVENING THROUGH SUNDAY NIGHT)  
ISSUED AT 246 PM CST THU FEB 20 2020  
 
A MID/UPPER RIDGE WAS SITUATED ACROSS THE SOUTHWEST EXTENDING  
NORTHWARD ACROSS THE CENTRAL GREAT BASIN AREA. DOWNSTREAM ACROSS THE  
CENTRAL PLAINS REGION, HIGH PRESSURE WAS BUILDING SOUTHWARD IN THE  
WAKE OF A COLD FRONT. DRY AND STABLE AIR IN THE WAKE OF THE FRONT  
ALLOWED CLEAR SKIES TO DEVELOP ACROSS THE REGION.  
 
AS HIGH PRESSURE TRANSLATES SLOWLY SOUTH AND EAST ACROSS THE AREA  
TONIGHT, THE BEST RADIATIONAL COOLING SHOULD OCCUR ACROSS MAINLY  
SOUTHEAST KS WITH SOUTHWESTERLY LOW LEVEL FLOW RETURNING TO WESTERN  
AND MUCH OF CENTRAL KS.  
 
TEMPERATURES WILL BE SLOW TO RECOVER ON FRIDAY WITH THE BEST LOW  
LEVEL WARM AIR ADVECTION EXPECTED ACROSS WESTERN AND PORTIONS  
OF CENTRAL KANSAS.  
 
SAT-SUN...THE LOW LEVEL THERMAL RIDGE WILL EXPAND INTO THE CENTRAL  
PLAINS OVER THE WEEKEND BRINGING MODERATING TEMPERATURES ON  
SATURDAY. BY SUNDAY, A VIGOROUS MID/UPPER TROUGH OVER THE SOUTHERN  
ROCKIES WILL EMERGE OVER THE SOUTHERN PLAINS BRINGING WIDESPREAD  
PRECIPITATION TO THE AREA ON SUNDAY-SUNDAY NIGHT. THE LATEST GFS  
CONTINUES TO TREND MUCH SLOWER RESULTING IN A SLOWER ARRIVAL OF  
PRECIPITATION AND WHAT LOOKS LIKE ANOTHER ROUND OF BENEFICIAL  
MOISTURE FOR MUCH OF THE FORECAST AREA. THE NAEFS STANDARDIZED  
ANOMALIES ARE INDICATING ABUNDANT MOISTURE AVAILABLE WITH THIS  
STORM SYSTEM WITH SPECIFIC HUMIDITIES OF 2-3 STANDARD DEVIATIONS  
ABOVE NORMAL THROUGH THE COLUMN WITH PRECIPITABLE WATER VALUES  
ALSO PROGGED TO BE 2-3 STANDARD DEVIATIONS ABOVE NORMAL. SO A  
SLOWER AND DEEPER EVOLUTION WHICH WE ALSO SEE IN THE LATEST ECMWF  
SHOULD RESULT IN A WETTER SCENARIO FOR THE CENTRAL PLAINS ON  
SUNDAY INTO MONDAY AND THE FORECAST WAS TRENDED IN THAT DIRECTION.  
INITIALLY, THE PRECIPITATION IS EXPECTED TO BE ALL RAIN, BUT A  
TRANSITION TO SNOW IS STILL POSSIBLE SUNDAY NIGHT INTO MONDAY WITH  
SOME DIFFERENCES IN TRACK AND AVAILABILITY OF COLD AIR REMAINING.  
   
LONG TERM
 
(MONDAY THROUGH THURSDAY)  
ISSUED AT 246 PM CST THU FEB 20 2020  
 
A ROBUST MID/UPPER TROUGH WILL BE IMPACTING THE CENTRAL PLAINS  
AND MIDDLE MISSISSIPPI VALLEY AREA AT THE START OF THE PERIOD AND  
THERE REMAINS SOME UNCERTAINTY IN HOW QUICKLY IT WILL DEPART.  
ANOTHER BLAST OF MODIFIED ARCTIC AIR WILL ARRIVE IN IT'S WAKE,  
MOST LIKELY MONDAY NIGHT INTO EARLY TUESDAY. MAINTAINED SOME LOWER  
POPS THROUGH EARLY IN THE WEEK AS A SUBTLE SHORTWAVE TROUGH  
ROTATES THROUGH THE AREA BUT CONFIDENCE IN THE DETAILS REMAINS  
RATHER LOW AT THIS TIME. NORTHWEST MID/UPPER FLOW WILL PREVAIL  
THROUGH THE REMAINDER OF THE FORECAST WITH BELOW NORMAL  
TEMPERATURES PREVAILING THROUGH THE PERIOD.  
 

 
   
AVIATION
 
(FOR THE 00Z TAFS THROUGH 00Z FRIDAY EVENING)  
ISSUED AT 527 PM CST THU FEB 20 2020  
 
VFR CONDITIONS THROUGHOUT THIS FORECAST PERIOD. ONLY ISSUE WILL BE  
GOING FROM LIGHT AND VARIABLE WINDS OVERNIGHT TO GUSTY SOUTHERLY  
WINDS DURING THE LATE MORNING. WITH THE LIGHT WINDS IF ANY FOG  
DOES DEVELOP, IT SHOULD BE PRETTY ISOLATED AND PATCHY. MORE  
CONCERN FOR FOG WILL BE TOMORROW NIGHT WITH THE SOUTHERLY FLOW AND  
WARM AIR ADVECTION MOVING OVER THE MOIST GROUND.
