Forecast discussion for Denver:
AREA FORECAST DISCUSSIONNATIONAL WEATHER SERVICE DENVER CO330 AM MST THU JAN 20 2005.
SHORT TERM...
EVERYTHING STILL ON TRACK FOR RECORD TEMPERATURES INDENVER TODAY. EARLY A.M. ACARS SOUNDING SHOWS INVERSION DEPTH ONLYABOUT 600-700 FT DEEP AROUND DIA AND PROBABLY EVEN SHALLOWER IN THE WESTERN SUBURBS WHERE CURRENT TEMPS IN THE MID 50S. ACARS SOUNDING SHOWS PARCEL TAKEN DOWN DRY ADIABATICALLY FROM 800 MB WOULD ALREADY YIELD 68F...AND MORE WARMING IN THAT LEVEL WOULD SUPPORT 72-75F FOR HIGHS. HOWEVER...THERE ARE A FEW THINGS TO WATCH OUR FOR TODAY. ONE IS MOUNTAIN WAVE ENHANCED CLOUDINESS WHICH FOR NOW HAS CONFINED ITSELF TO WYOMING. THE SHORT RANGE MODELS SEEM CONSISTENT IN ATTEMPTING TO SPREAD SOME OF THE MOISTURE INTO OUR FORECAST AREA WHICH COULD LEAD TO SOME CLOUDS. THINK MOSTLY SUNNY SHOULD SUFFICE FOR NOW THOUGH SINCE WATER VAPOR SHOWS UPPER LEVEL MOISTURE QUITE SPARSE UPSTREAM. SECOND THING IS DOWNSLOPE FLOW DECREASES DURING THE DAY. HOWEVER...INVERSIONS ARE ALREADY QUITE SHALLOW SO THINK 70F IS QUITE LIKELY ATDIA AND A FEW SPOTS IN THE WESTERN SUBURBS COULD
REACH 75F. VERYWARM IN THE MOUNTAINS AS WELL. SPRING SKIING SHOULD BE IN FULL FORCE TODAY WITH HIGHS MOSTLY IN THE 40S AND EVEN SOME 50S IN THE MOUNTAIN VALLEYS.
LONG TERM...A RATHER SIGNIFICANT SHORT WAVE WILL MOVE OVER THE BIG WESTERN U.S. RIDGE FRIDAY AND FRIDAY NIGHT. MID LEVEL COLD ADVECTION BEGINS TOMORROW MORNING...BUT THEN LOW LEVEL COLD ADVECTION REALLY KICKS IN FRIDAY NIGHT AND EARLY SATURDAY AS SURGE OF ARCTIC AIR MOVES SOUTH ACROSS THE CENTRAL PLAINS. WHILE WE WILL ONCE AGAIN BE ON THE EDGE OF ANOTHER ARCTIC
BLAST...WILL STILL HAVE TO LOWER HIGH TEMPS FOR SATURDAY BY ABOUT 10F DEGREES OVER THE PLAINS. IDEA OF ISOLATED SNOW SHOWERS IN MOUNTAINS WITH COLD ADVECTION AND VERY SHALLOW MOISTURE LOOKS GOOD.NOT MUCH NEW FOR SUNDAY THROUGH
NEXT WEDNESDAY. WARM ADVECTION MONDAY AND TUESDAY WITH WELL ABOVE NORMAL TEMPS EXPECTED. THEN POTENTIALLY SOME MODERATION THROUGH MID WEEK. PACIFIC IS GETTING ACTIVE AGAIN SO THE SOUTHWEST U.S. SHOULD TRANSITION INTO A MORE WINTERLIKE WEATHER PATTERN BEGINNING NEXT WEEKEND. .
BOU WATCHES/WARNINGS/ADVISORIES...
NONE.
