..UPDATED AVIATION SECTION
 
 
   
SHORT TERM
 
(TODAY AND TONIGHT)  
ISSUED AT 258 AM CST TUE DEC 12 2017  
 
MUCH CALMER AND MILD CONDITIONS CAN BE EXPECTED TODAY ACROSS  
CENTRAL AND SOUTHWEST KANSAS. THE UPPER LEVEL SHORTWAVE TROUGH  
THAT BROUGHT THE COLD FRONT THROUGH WESTERN KANSAS ON MONDAY HAS  
MOVED OFF INTO THE EASTERN SECTIONS OF THE COUNTRY. SURFACE HIGH  
PRESSURE BEHIND THE FRONT WAS MOVING SOUTH ACROSS FAR WESTERN  
KANSAS EARLY THIS MORNING. AS THIS CONTINUES SOUTH, LOW LEVEL WARM  
ADVECTION ON WESTERLY DOWNSLOPE FLOW WILL DEVELOP ACROSS THE  
FORECAST AREA. THINK THAT THE GOING TEMPERATURE FORECAST OF HIGHS  
IN THE MID/UPPER 50S TO LOW 60S IS NOT TOO FAR OFF GIVEN THAT LOW  
LEVEL MIXING AND DOWNSLOPE WIND FLOW WILL NOT HAVE QUITE THE  
IMPACT AS ON MONDAY. THE GOING FORECAST LEANS TOWARD THE WARMEST  
MODEL/MOS GUIDANCE NUMBERS AND HAVE STAYED FAIRLY CLOSE TO IT, IF  
NOT ADDING A DEGREE OR TWO HERE AND THERE.  
 
WESTERLY DOWNSLOPE WIND FLOW WILL CONTINUE INTO TONIGHT AND COULD  
ACTUALLY INCREASE SOMEWHAT FROM THE NORTHWEST TOWARD WEDNESDAY  
MORNING IN ADVANCE OF THE NEXT COLD FRONT. LOW TEMPERATURES SHOULD  
BE A FEW DEGREES WARMER THAN THIS MORNING, GENERALLY IN THE LOW  
TO MID 30S.  
   
LONG TERM
 
(WEDNESDAY THROUGH MONDAY)  
ISSUED AT 258 AM CST TUE DEC 12 2017  
 
ANOTHER FAST MOVING SHORTWAVE TROUGH AND ASSOCIATED SURFACE COLD  
FRONT WILL PUSH SOUTH THROUGH THE CENTRAL HIGH PLAINS EARLY ON  
WEDNESDAY. LOW ATMOSPHERIC TEMPERATURES BEHIND THIS FRONT LOOK  
SIMILAR, IF NOT A DEGREE OR TWO COOLER, TO THE FRONT ON MONDAY.  
EXPECT HIGH TEMPERATURES TO TOP OUT IN THE UPPER 50S TO LOW 60S.  
ON THE HEELS OF THIS WAVE, ANOTHER SHORTWAVE TROUGH WILL DROP  
SOUTH OVER THE EASTERN SLOPES OF THE ROCKIES AND ADJACENT HIGH  
PLAINS. MOISTURE WITH THIS SYSTEM WILL BE LACKING SO ONLY SOME MID  
AND HIGH LEVEL CLOUDINESS IS EXPECTED. COOLER AIR WILL BE SPREADING  
SOUTHWARD INTO WESTERN KANSAS WITH THIS SYSTEM. HIGHS ON THURSDAY  
MAY STRUGGLE TO REACH 50 DEGREES OVER MUCH OF THE AREA.  
 
ANOTHER STRONG SHORTWAVE TROUGH IS EXPECTED TO DIG A LITTLE DEEPER  
INTO THE CENTRAL AND SOUTHERN PLAINS AS IT MOVES OUT OF THE  
PACIFIC NORTHWEST SATURDAY INTO SATURDAY NIGHT.THIS WAVE COULD  
ACTUALLY BRING SOME MUCH NEEDED MOISTURE TO THE HIGH PLAINS. THE  
00Z RUN OF THE SUPERBLEND PAINTS SOME SLIGHT CHANCE POPS OVER FAR  
SOUTHWEST KANSAS SATURDAY NIGHT. WILL LEAVE THIS FORECAST INTACT  
FOR NOW. GIVEN THE POSITIVE TILT CONFIGURATION OF THIS WAVE PLUS  
THE CONTINUED LACK OF DECENT LOW LEVEL MOISTURE, AM INCLINED TO  
THINK THAT ANY MEASURABLE RAIN OR SNOW THAT DOES OCCUR WITH THIS  
SYSTEM WILL BE CONFINED TO THE UPSLOPE FAVORED AREAS ALONG THE  
COLORADO FRONT RANGE.  
 

 
   
AVIATION
 
(FOR THE 12Z TAFS THROUGH 12Z WEDNESDAY MORNING)  
ISSUED AT 423 AM CST TUE DEC 12 2017  
 
VFR CONDITIONS WILL PREVAIL TODAY WITH MOSTLY CLEAR SKIES. WINDS  
WILL START OUT FROM THE NORTHWEST THIS MORNING SHIFTING TO MORE OF  
A WESTERLY DIRECTION BY THIS AFTERNOON.  
 

 
   
FIRE WEATHER
 
 
ISSUED AT 258 AM CST TUE DEC 12 2017  
 
A STRONG COLD FRONT WILL PUSH THROUGH WESTERN KANSAS EARLY  
WEDNESDAY WITH NORTHERLY WINDS INCREASING BEHIND THE FRONT. MODEL  
TRENDS WITH THIS SYSTEM ARE STILL SUGGESTING THAT RELATIVE  
HUMIDITY LEVELS WILL FALL INTO THE UPPER TEENS TO 20 PERCENT  
DURING THE DAY...ABOVE CRITICAL RH LEVELS. STILL, IT WILL BE A  
GOOD DAY TO AVOID OUTDOOR BURNING GIVEN THE GUSTY WINDS.
