NATIONAL WEATHER SERVICE GOODLAND KS  
304 AM MST FRI DEC 20 2024

- BRIEFLY COOLER DOWN MAINLY EAST OF HIGHWAY 25 WITH A COLD  
FRONT PUSHING THROUGH THE AREA, BUT STILL ONLY SLIGHTLY BELOW  
NORMAL.  
 
- DRY CONDITIONS AND GENERALLY ABOVE NORMAL TEMPERATURES  
CONTINUE INTO EARLY NEXT WEEK.  
 
- LOW CHANCE (30%) OF PRECIPITATION AROUND CHRISTMAS.  
 
 
   
SHORT TERM /THROUGH SUNDAY NIGHT/  
 
ISSUED AT 303 AM MST FRI DEC 20 2024  
 
ACROSS THE REGION THIS MORNING, CLEAR SKIES PREVAIL AS A COLD FRONT  
IS CURRENTLY MOVING THROUGH THE AREA, WITH A STRONG SURFACE RIDGE  
BEHIND IT THAT STRETCHES INTO THE NORTHERN PLAINS. WITH THE RIDGE  
NOSING SOUTH INTO THE AREA, WINDS ARE LIGHT/VARIABLE AT THIS  
TIME(200 AM MST). WITH THE LIGHT WINDS AND CLEAR SKIES, DECENT  
RADIATIONAL COOLING EFFECTS AS TEMPERATURES ARE RANGING IN THE TEENS  
TO LOWER 20S.  
 
THE LATEST RAP40 500MB ANALYSIS IN COMBINATION WITH MID LEVEL WATER  
VAPOR IMAGERY IS SHOWING AN AMPLIFIED RIDGE OVER THE WESTERN PORTION  
OF THE COUNTRY, AND A BROAD TROUGH EAST. THIS PUTS THE TRI STATE  
AREA IN BETWEEN THESE SYSTEMS, ALLOWING FOR NW FLOW ALOFT TO  
PERSIST. THE LATEST RUNS OF THE GFS/NAM DO SHOW THE RIDGE TO THE  
WEST SLOWLY TREK EAST GOING INTO THE UPCOMING WEEKEND, WITH ZONAL  
FLOW EVENTUALLY BY SUNDAY.  
 
AT THE SURFACE, THE RIDGE OVER THE PLAINS REGION WILL SLOWLY MOVE  
EAST DURING THE DAY, ALLOWING FOR SOUTHERLY FLOW TO INCREASE OVER  
LOCALES WEST OF HIGHWAY 25. THE COLD POOL FROM THE ARRIVAL OF THE  
HIGH PRESSURE SYSTEM WILL REMAIN IN THE EAST THROUGH THE DAY, AS THE  
SOUTHERLY FLOW WILL NOW PUSH FAR ENOUGH EAST TO BE IMPACTFUL. THE  
SOUTHERLY FLOW OVER THE WEST WILL BE AIDED BY A DEVELOPING LEE-SIDE  
TROUGH OVER EASTERN COLORADO. THIS DOES PUSH EAST OVERNIGHT,  
ALLOWING FOR SOUTHERLY FLOW TO SHIFT MORE W/NW.  
 
GOING INTO THIS WEEKEND, THE TROUGH RESETS OVER EASTERN COLORADO  
SATURDAY. WITH THE SURFACE RIDGE FURTHER EAST OF THE AREA, THE  
SOUTHERLY WARMING FLOW WILL EXPAND AREA-WIDE. WITH NO  
MOISTURE/SYSTEM PUSHING INTO THE AREA, NO PRECIP IS EXPECTED. A LOW  
DEVELOPS ALONG THE TROUGH ON SUNDAY AND DIPS SOUTH DURING THE DAY.  
OVERALL FOR THE WEEKEND, ABOVE NORMAL TEMPS ARE EXPECTED. WITH THE  
DRY AIRMASS IN PLACE, RH VALUES DURING THE AFTERNOON HOURS EACH DAY  
WILL APPROACH THE 20% MARK. AND WITH WINDS PEAKING AROUND 10-20 MPH  
AT BEST, THINKING ANY FIRE WX CONCERNS WILL REMAIN LOW, BUT WILL BE  
MONITORED NONETHELESS.  
 
FOR TEMPS, WITH THE COLD FRONT ACROSS THE REGION TODAY, THERE WILL  
BE A WIDE RANGE FOR HIGHS. LOOKING FOR AREAS ALONG/EAST OF HIGHWAY  
83 TO SEE MID 30S TO AROUND 40F. LOWER TO MID 40S WEST OF HIGHWAY 83  
THROUGH THE HIGHWAY 25 CORRIDOR. WEST OF HIGHWAY 25 INTO COLORADO,  
UPPER 40S TO MID 50S EXPECTED, WITH WARMEST LOCALES ALONG/WEST OF  
HIGHWAY 27.  
 
GOING INTO THIS WEEKEND, SATURDAY WILL HAVE MID 40S TO MID 50S EAST  
OF HIGHWAY 25. WEST OF THERE, MID 50S TO LOWER 60S. GOING INTO  
SUNDAY, 60S EXPECTED AREA-WIDE.  
 
OVERNIGHT LOWS TONIGHT MAINLY IN THE 20S, WITH SOME MID TO UPPER  
TEENS ALONG/EAST OF HIGHWAY 83. FOR THIS WEEKEND, 20S EXPECTED EACH  
NIGHT, WITH SOME ISOLATED 30F POSSIBLE.  
 
 
   
LONG TERM /MONDAY THROUGH THURSDAY/  
 
ISSUED AT 223 AM MST FRI DEC 20 2024  
 
LITTLE CHANGE IN THE FORECAST FOR CHRISTMAS WEEK. THE UPPER PATTERN  
REMAINS FORECAST TO START ZONAL, AND THEN SEE MULTIPLE TROUGHS MOVE  
IN FROM THE WEST WITH MORE PERSISTENT TROUGHING FORECAST FOR THE END  
OF THE WEEK. THIS WILL GENERALLY KEEP TEMPERATURES AROUND AVERAGE  
WITH HIGHS BETWEEN THE 30'S AND 50'S WHILE LOWS ARE FORECAST TO BE  
IN THE 20'S. WHILE FORECAST 850MB TEMPERATURES COULD SUPPORT SOME  
HIGHS NEAR 60 (ESPECIALLY TO START THE WEEK), WAVES OF CLOUD COVER  
MOVING IN WITH THE UPPER WAVES ARE FORECAST TO HELP KEEP  
TEMPERATURES A BIT COOLER DURING THE DAY, AND A BIT WARMER AT NIGHT.  
FOR MON/TUES, NO PRECIPITATION IS EXPECTED AS MOISTURE IS FORECAST  
TO REMAIN ELEVATED (GENERALLY 700MB AND HIGHER) WITH MOISTURE MOVING  
OVER THE MOUNTAINS FROM THE WEST.  
 
LATER CHRISTMAS DAY AND INTO THURSDAY, LOW CHANCES FOR LIGHT  
RAIN/SNOW SHOWERS REMAIN FORECAST AND LOOK A BIT BETTER AS THE  
TROUGH AT MID-WEEK IS FAVORED TO TAKE A BIT MORE OF A SOUTHERLY  
TRACK. THIS WOULD KEEP THE SURFACE LOW JUST SOUTH OF THE AREA  
AND ALLOW SOME LOWER LEVEL MOISTURE TO MOVE IN FROM THE  
SOUTHEAST. IF ENOUGH MOISTURE MOVED IN AND THE TROUGH DIDN'T DIG  
TOO FAR SOUTH AND TAKE THE FORCING OUT OF THE AREA, SOME  
SHOWERS COULD FORM EITHER CHRISTMAS DAY OR THE DAY AFTER.  
PRECIPITATION WOULD BE RAIN DURING THE DAY AND SNOW AT NIGHT  
WITH NO SUGGESTION OF A STRONG COLD AIR MASS MOVING IN AND  
KEEPING PRECIPITATION AS SNOW. CURRENT ENSEMBLES KEEP QPF  
GENERALLY BELOW A TENTH OF AN INCH WITH MOST STILL SHOWING NO  
QPF. SO EVEN IF PRECIPITATION DID FALL (30% CHANCE), IT WOULD  
LIKELY BE JUST ENOUGH TO WET THE GROUND OR GIVE A TRACE OF SNOW.  
WINDS ARE CURRENTLY NOT EXPECTED TO BECOME A HAZARD WITH  
GENERALLY WEAK HEIGHT GRADIENTS AND THE LOW PRESSURE SYSTEMS  
FORECAST TO MOVE THROUGH FAIRLY QUICKLY AND WITHOUT DEEPENING  
TOO MUCH.
