..AVIATION UPDATE
 
 
   
SHORT TERM
 
(THIS EVENING THROUGH WEDNESDAY)  
ISSUED AT 245 PM CST TUE JAN 23 2018  
 
THE WEATHER HAS BEEN QUIET TODAY ASIDE FROM SOME MORNING FOG AT  
KJYR ON THE BACK EDGE OF THE STRATUS. THE FOG/VISIBILITY  
RESTRICTIONS WERE SHORTLIVED AS THE STRATUS MIGRATED TO THE EAST  
AND WINDS INCREASED FROM THE WEST.  
 
TODAY IS A TRANSITION DAY IN BETWEEN THE STORM SYSTEM WHICH PRODUCED  
BLIZZARD CONDITIONS ON MONDAY AND WARMER WEATHER POISED TO MOVE IN  
FOR THE MIDDLE OF THE WEEK. DESPITE THE RECENT SNOWFALL,  
TEMPERATURES HAVE RISEN NICELY INTO THE 30S AND 40S TODAY AIDED  
BY A WESTERN DOWNSLOPE WIND. BETWEEN THE SETTLING AND MELTING OF  
THE SNOW, THE MIDDAY SNOW DEPTH HAD ALREADY LOWERED BY A HALF OF  
AN INCH AT WFO HASTINGS.  
 
AS WE HEAD INTO TONIGHT THE SHORTWAVE TROUGH CROSSING THE PLAINS  
TODAY, BRINGING THE MID/HIGH LEVEL CLOUD COVER TO OUR AREA WILL  
DEPART TO THE EAST WITH DECREASING CLOUDS FOR THE OVERNIGHT HOURS.  
ANY MELTING WHICH OCCURRED TODAY WILL REFREEZE AS TEMPERATURES  
DROP INTO THE TEENS/LOW 20S FOR LOWS. HAVE SOME CONCERN FOR THE  
POTENTIAL FOR FOG DEVELOPMENT, HOWEVER WITH THE REFREEZE AND  
DOWNSLOPE WIND COMPONENT HAVE NOT INCLUDED IN THE FORECAST AT THIS  
TIME.  
 
WARMER WEATHER AND MORE SNOWMELT WILL BE UNDERWAY ON WEDNESDAY IN  
RISING HEIGHTS AS UPPER RIDGING EXPANDS EAST OF THE ROCKIES. THE  
COMBINATION OF THE WARMER AIRMASS AND A WEST TO SOUTHWEST  
DOWNSLOPE WIND COMPONENT OFF A LESSER SNOWPACKED AREA WILL LEAD  
TO NOTICEABLY WARMER TEMPERATURES WELL INTO THE 30S AND 40S IN  
SNOW AREAS, WITH 50S FORECAST IN NON-SNOW LOCATIONS.  
   
LONG TERM
 
(WEDNESDAY NIGHT THROUGH TUESDAY)  
ISSUED AT 245 PM CST TUE JAN 23 2018  
 
THE EXTENDED PERIODS REMAIN QUIET WITH DRY WEATHER FORECAST INTO  
NEXT WEEK. THE WARMEST DAY OF THE WEEK IS EXPECTED ON THURSDAY AS  
SUBTLE UPPER RIDGING SETTLES ACROSS THE PLAINS STATES, AND FLOW  
GRADUALLY TRANSITIONS SOUTHWEST AHEAD OF A WESTERN TROUGH. SOUTHERLY  
WINDS WILL BE ON THE INCREASE THROUGH THE AFTERNOON AND COMBINED  
WITH ANOTHER DAY OF TEMPS IN THE 40S AND 50S, ANY RESIDUAL SNOW  
SHOULD ERODE. THEN ON FRIDAY, A COLD FRONT AND UPPER TROUGH  
PASSAGE WILL COOL THINGS DOWN SEVERAL DEGREES, BUT STILL MILD FOR  
JANUARY.  
 
A REINFORCING SHOT OF COLD AIR ARRIVES SATURDAY WITH A CLIPPER  
SYSTEM AND BACK DOOR COLD FRONT, THEN SUNDAY WILL BE THE  
TRANSITION DAY BETWEEN SYSTEMS, WITH A WARMER AND FAIRLY ZONAL  
PATTERN EXPECTED FOR THE FIRST PART OF NEXT WEEK.  
 

 
   
AVIATION
 
(FOR THE 06Z KGRI/KEAR TAFS THROUGH 06Z WEDNESDAY)  
ISSUED AT 1106 PM CST TUE JAN 23 2018  
 
VFR CONDITIONS EXPECTED THROUGH THIS TAF PERIOD. BASED ON  
RAP/HRRR, IT APPEARS THAT ANY FOG SHOULD DEVELOP EAST OF THE  
FORECAST AREA TONIGHT INTO WEDNESDAY MORNING.  
 
WESTERLY WINDS BECOME SOUTHWESTERLY TODAY UNDER MOSTLY CLEAR  
SKIES.  
 
WE WILL BE KEEPING AN EYE ON THE POTENTIAL FOR FOG WEDNESDAY  
NIGHT, BUT THIS IS JUST BEYOND THE TAF PERIOD FOR NOW.
