UPDATE
 
 
ISSUED AT 826 PM MDT SAT MAR 28 2020  
 
NO MAJOR UPDATES THIS EVENING. ADJUSTED THE TIMING REGARDING THE  
POPS AND WINDS THIS EVENING, BOTH OF WHICH CONTINUE TO DECREASE.  
OTHERWISE, THE REST OF THE GRIDS LOOK GOOD.  
 

 
   
SHORT TERM
 
(THIS EVENING THROUGH SUNDAY)  
ISSUED AT 317 PM MDT SAT MAR 28 2020  
 
WE'RE SEEING A FEW LIGHT SHOWERS ON THE BACK EDGE OF THE CLOUD  
SHIELD OVER THE EASTERN PART OF THE PLAINS, AND ALSO OVER THE  
MOUNTAINS. NONE OF THIS SHOULD PRODUCE ACCUMULATIONS. THE WIND HAS  
BEEN A LITTLE LESS THAN EARLIER EXPECTED AND HAS HAD TROUBLE  
GETTING GOING STEADILY IN THE DENVER AREA, SO WE'VE BACKED OFF OF  
THE WINDS FOR THE REST OF THE AFTERNOON. THE DECREASING GRADIENT  
SHOULD BRING SOME LESSENING DURING THE LATE AFTERNOON AND A QUICK  
DROP OFF AFTER SUNSET.  
 
THE SHALLOW MOISTURE LAYER UPSTREAM OF THE FRONT RANGE SHOULD  
PERSIST OVERNIGHT THOUGH IT WILL LIKELY HAVE SOME HOLES IN IT.  
A FEW FLURRIES WILL HANG ON AS WELL. SUNDAY MORNING WILL BRING  
INCREASING MID AND HIGH CLOUDS FROM THE SOUTHWEST SPREADING INTO  
THE CENTRAL MOUNTAINS BY MIDDAY AND ACROSS MOST OF THE PLAINS  
DURING THE AFTERNOON. IT SHOULD STILL GET WARM ENOUGH FOR SOME  
SCATTERED LIGHT SNOW SHOWERS OVER THE MOUNTAINS IN THE LATE  
AFTERNOON. LIGHT AMOUNTS AND WARM TEMPERATURES SHOULD AGAIN KEEP  
ACCUMULATIONS TO A MINIMUM. TEMPERATURES SHOULD BE 5 TO 10 DEGREES  
WARMER THAN TODAY.  
   
LONG TERM
 
(SUNDAY NIGHT THROUGH SATURDAY)  
ISSUED AT 317 PM MDT SAT MAR 28 2020  
 
AN UPPER TROUGH APPROACHING THE STATE FROM THE WEST WILL BE  
PRODUCING LIGHT SNOW IN THE MOUNTAINS TOMORROW NIGHT. AS THE  
TROUGH AXIS PROGRESSES OUT ONTO THE PLAINS MONDAY, SOME SHOWERS  
AND POSSIBLY A FEW THUNDERSTORMS ON THE FAR EASTERN PLAINS. THIS  
TROUGH WILL MOVE OUT OF THE STATE MONDAY EVENING WITH A DRYING  
TREND OVERNIGHT. MEDIUM RANGE MODELS ARE ALL IN AGREEMENT FOR THE  
MONDAY NIGHT THROUGH THURSDAY PERIOD WITH AN UPPER RIDGE BUILDING  
OVER THE STATE AS THE FLOW ALOFT TRANSITIONS TO NORTHWESTERLY.  
FLOW ALOFT WILL BE INCREASING WHICH MAY PICK UP THE SURFACE WIND  
SPEEDS OVER THE MOUNTAINS AND EASTERN SLOPES, MAINLY TUESDAY AND  
TUESDAY EVENING. BY WEDNESDAY MORNING THE UPPER LEVEL JET WILL BE  
SLIDING FAR ENOUGH EAST AND NORTHWARD TO REDUCE THE AMOUNT OF  
SUBSIDENT FORCING OVER THE STATE. MOUNTAIN AREAS WILL SEE LIGHT,  
OROGRAPHIC SNOW SHOWERS THROUGH THE MIDDLE OF THE WEEK, BUT  
AMOUNTS WILL BE LIGHT. FOR THE LATTER HALF OF THE WEEK, ZONAL FLOW  
ALOFT WILL CONTINUE ACROSS THE STATE WHICH WILL KEEP TEMPERATURES  
AROUND SEASONAL NORMALS WITH SOME SNOW SHOWERS CONTINUING IN THE  
MOUNTAINS. AGAIN, ANY ACCUMULATIONS ARE EXPECTED TO BE LIGHT.  
 

 
   
AVIATION

ISSUED AT 826 PM MDT SAT MAR 28 2020  
 
VFR THROUGH SUNDAY. WESTERLY WINDS 10-15 KTS WILL WEAKEN SOMEWHAT  
AS THEY CONTINUE TO TRANSITION TO DRAINAGE BY 04Z.
