SHORT TERM
 
(THIS EVENING THROUGH MONDAY)  
ISSUED AT 137 PM MST SUN DEC 4 2016  
 
CURRENTLY ACROSS THE TRI-STATE REGION THERE IS A SURFACE RIDGE. THIS  
IS ALLOWING TEMPERATURES TO REACH THE UPPER 40S TO LOW 50S. THE MAIN  
PORTION OF SURFACE RIDGE IS IN THE EASTERN PORTION OF THE AREA,  
THEREFORE THIS IS BRINGING SOUTHWEST FLOW ACROSS THE CWA. WINDS ARE  
PRIMARILY LIGHT AT 5 TO 10 MPH BUT SOME GUSTY WINDS HAVE DEVELOPED  
OVER THE EASTERN COLORADO COUNTIES AND NEBRASKA COUNTIES EARLY THIS  
AFTERNOON.  
 
THE REMAINDER OF THE DAY INTO THE EVENING ARE EXPECTED TO BE DRY  
WITH WINDS FROM THE WEST, SOUTHWEST AT 5 TO 15 MPH. THERE WILL BE  
SOME HIGH CLOUDS THAT MOVE INTO THE NORTHWEST HALF OF THE REGION  
THIS EVENING AS A SURFACE TROUGH BEGINS TO PUSH EAST INTO THE  
REGION. TEMPERATURES WILL DROP INTO THE 20S TONIGHT.  
 
AS FOR MONDAY, TEMPERATURES WILL BE IN THE 50S DUE TO WARM AIR  
MOVING ACROSS THE REGION BEFORE A COLD FRONTAL PASSAGE. CURRENT  
GUIDANCE HAS THIS COLD FRONT MOVING OVER THE REGION DURING THE MID  
TO LATE AFTERNOON HOURS. THIS WILL CAUSE THE WINDS TO SHIFT TO THE  
NORTHWEST AND INCREASE TO AROUND 10 TO 20 MPH.  
   
LONG TERM
 
(MONDAY NIGHT THROUGH SUNDAY)  
ISSUED AT 221 PM MST SUN DEC 4 2016  
 
THE FORECAST CONCERNS IN THE LONG TERM ARE THE COLD AIR MOVING  
INTO THE REGION MID-WEEK FOLLOWING THE POSSIBILITY OF ACCUMULATING  
SNOW FROM TUESDAY NIGHT NIGHT THROUGH WEDNESDAY.  
 
THE CLOSED UPPER LOW THAT HAS BEEN TRACKING SLOWLY ACROSS  
NORTHERN MEXICO AND IS EXPECTED TO MOVE ACROSS TEXAS ON MONDAY  
AND MONDAY NIGHT WILL LIFT QUICKLY INTO THE MISSISSIPPI VALLEY  
REGION AS AN OPEN TROUGH BY TUESDAY MORNING AHEAD OF A KICKER THAT  
MOVES EAST OF THE ROCKIES AND ACROSS THE NORTHERN PLAINS BY MONDAY  
EVENING.  
 
IN THE WAKE OF THIS SYSTEM, VERY COLD AIR DIVES SOUTH ALONG THE  
HIGH PLAINS ON TUESDAY. AS A RESULT, HIGH TEMPERATURES WILL DROP  
FROM THE 50S ON MONDAY INTO THE 30S ON TUESDAY. RETURN SURFACE  
FLOW AROUND THE HIGH PRESSURE AREA AS IT MOVES EAST ALONG WITH AN  
INVERTED SURFACE TROUGH MOVING INTO THE SOUTHERN HIGH PLAINS WILL  
FOCUS MOISTURE, MAINLY AT AND BELOW 700MB, ON THE REGION. AS THIS  
MOISTURE MOVES OVER AND INTO THE COLDER AIR, EXPECT LIGHT SNOW TO  
DEVELOP ACROSS THE REGION WITH A POSSIBLE BAND OF SNOW NEAR AN  
AREA OF FRONTOGENESIS STRETCHED ACROSS THE FORECAST AREA IN THE  
VICINITY OF INTERSTATE 70. CURRENT THINKING IS A FAIRLY WIDESPREAD  
AREA OF 2-4" OF SNOW IS EXPECTED WITH LOCALIZED HIGHER AND LOWER  
AMOUNTS. SOME AREAS OF BLOWING SNOW MAY BE OBSERVED AS THE  
STRONGER PRESSURE GRADIENT TRANSITIONS ACROSS MAINLY THE SOUTHERN  
PORTION OF THE FORECAST AREA ALONG WITH THE PEAK SNOWFALL BETWEEN  
06Z TUESDAY NIGHT AND 18Z WEDNESDAY MID DAY.  
 
AS THE INVERTED SURFACE TROUGH CONTINUES TO MOVE ACROSS THE  
SOUTHERN PLAINS, ANOTHER SURGE OF COLDER HIGH PRESSURE MOVES IN  
ACROSS THE CENTRAL HIGH PLAINS REGION ON WEDNESDAY AND WEDNESDAY  
NIGHT. SNOW IS EXPECTED TO COME TO AN END BY WEDNESDAY AFTERNOON.  
HIGH TEMPERATURES ON WEDNESDAY ARE ONLY EXPECTED TO BE IN THE  
TEENS TO LOWER 20S. WITH HIGH PRESSURE MOVING IN WEDNESDAY NIGHT  
AND SKIES BEGINNING TO CLEAR OUT, ESPECIALLY IN THE WEST, EXPECT  
TEMPERATURES TO DROP TO AROUND ZERO WITH WIND CHILLS IN THE TEENS  
BELOW ZERO POSSIBLE. WEDNESDAY AND WEDNESDAY NIGHT WILL HAVE THE  
COLDEST TEMPERATURES OF THE PERIOD. THURSDAY AND THURSDAY NIGHT  
WILL REMAIN COLD, BUT NOT AS COLD AS WEDNESDAY. AS THE COLD AREA  
OF HIGH PRESSURE MOVES OUT OF THE REGION BY THE END OF THE WEEK,  
EXPECT TO SEE HIGH TEMPERATURES BACK UP INTO THE 30S AND LOWER 40S  
BY SATURDAY. MODELS HINT AT A LITTLE SPOTTY MIXED PRECIPITATION IN  
THE FORECAST BORDER REGIONS THROUGH THE WEEKEND AS WEAK WAVES  
TRANSITION THE REGION IN THE WESTERLY FLOW ALFOT, BUT WITH A LACK  
OF A STRONGER SYSTEM AND BETTER CONSENSUS BETWEEN MODEL  
SOLUTIONS, NOT EXPECTING MUCH IF ANYTHING IN THE WAY OF  
ACCUMULATIONS.
