AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
230 PM MDT MON APR 17 2006

.SHORT TERM DISCUSSION...STG SWLY WINDS THIS AFTN...SINGLE DIGIT
RELATIVE HUMIDITIES AND RECORD TEMPERATURES...HAVE WARRANTED THE
CONTINUATION OF THE RED FLAG WARNING FOR THE FRONT RANGE FOOTHILLS
...URBAN CORRIDOR AND ADJACENT PLAINS THROUGH 9 PM.  THE NEXT SYSTEM
OVER NRN UT AT 00Z IS PROGGED TO SHIFT INTO CNTRL WY AT 12Z AND
SOUTH DAKOTA BY 00Z.  BOTTOM LINE IS THAT THE MTNS WILL RECIEVE MOST
OF THE PCPN WITH THIS SYSTEM. BEST UPWARD QG OMEGA WILL OCCUR
TNGT...WITH STG SUBSIDENCE DVLPG BY 18Z TUESDAY AND CONTINUING INTO
THE AFTN.  SUFFICIENT MSTR...INSTBY AND OROGRAPHICS TO PROMPT A SNOW
ADVSY FOR THE MTNS TNGT THROUGH TUESDAY...BEST WINDOW WOULD APPEAR
TO BE FM 06Z-18Z TUESDAY. STRONGEST WINDS WILL ACTUALLY OCCUR THIS
EVENING AHEAD OF THE UPPER TROF BEFORE THE PCPN ARRIVES.  FOR THE
FRONT RANGE AND ADJACENT PLAINS...BEST CHC FOR PCPN WOULD APPEAR TO
BE ALONG THE NRN BORDER AND POSSIBLY THE PALMER DIVIDE SO WL KEEP
SCT POPS THERE.  STG DOWNSLOPE ELSEWHERE...SO WL DROP POPS BACK TO A
SLGT CHC.  STRONG COLD AIR ADVECTION AND SUBSIDENCE COUPLE WITH A
TIGHTENING NW-SE SFC PRESSURE GRADIENT WILL MAKE FOR VERY STG BORA
WINDS TUESDAY...ESPECIALLY IN THE NE PLAINS IN THE AFTN.  FOR THIS
REASON WILL GO AHEAD AND HOIST A HIGH WIND WATCH FOR PARTS OF THE
NORTHEAST PLAINS ON TUESDAY.

.LONG TERM DISCUSSION...THE UPPER LOW WILL MEANDER AROUND THE UPPER
MIDWEST THRU THURSDAY WITH RIDGING ALOFT SLOWLY BUILDING INTO THE
GREAT BASIN. THERE WILL STILL BE SOME LOW LVL MSTR ACROSS THE MTNS
TUE NIGHT BUT MSTR DEPTH IS FAIRLY SHALLOW...SO ONLY SCT ACTIVITY IN
THE EVENING. GRADUAL WARMING TREND THRU THE END OF THE WEEK WITH
DIMINISHING WINDS ON THE PLAINS TUE NIGHT.

THE NEXT SYSTEM WILL BEGIN TO EFFECT THE REGION NEXT SUNDAY AND
MONDAY TIME FRAME WITH THE NEXT CHANCE OF PRECIP AND COOLER TEMPS.
