AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DENVER CO 305 PM MDT THU APR 14 2011 .SHORT TERM...RATHER STRENOUS SHIFT WITH MOSTLY SNOW ACROSS PLAINS...WITH SOME MIX OF RAIN FAR NORTHEAST CORNER. SOME LIGHT SNOW CONTINUING ACROSS MOUNTAINS...MAINLY ALONG CONTINENTAL DIVIDE. UPPER LOW WRAPPED NICELY IN SOUTHWEST KANSAS WITH QUITE A BIT OF MOISTURE/PRECIPITATION OVER NORTHEAST CORNER. RADAR ALSO SHOWING SOME PRECIPITATION OVER NORTHERN WELD AND NORTHEAST LARIMER COUNTIES. WITH EARLIER REPORTS OF MODERATE SNOW ACROSS WASHINGTON AND SOUTHERN LOGAN COUNTIES...NEEDED TO ISSUE WINTER WEATHER ADVISORY FOR NORTHEAST CORNER UNTIL 02Z THIS EVENING. THIS TIMING STILL ON TRACK AS UPPER LOW SHIFTS INTO CENTRAL KANSAS DURING THE EVENING AND DRIER AIR WORKS INTO REGION. SNOW SHOWERS ACROSS MOUNTAINS WILL ALSO BE ON THE DECREASE DURING THE EVENING AS THE MOISTURE DECREASES AND SUBSIDENCE MOVES ACROSS CFWA. BY MIDNIGHT... DRIER SUBSIDENT AIRMASS TO BE ACROSS MUCH OF AREA...WILL KEEP SOME SNOW SHOWERS GOING FAR NORTHEAST CORNER. OTHER WEATHER ELEMENT OF CONCERN IS THE WIND. MODELS SHOW TIGHTENING NORTHWEST GRADIENT ACROSS NORTHEAST CORNER TONIGHT IN RESPONSE TO EXITING UPPER LOW BEGING REPLACED WITH STRONG SUBSIDENCE. LATEST RUC INDICATING 50 KTS ROUGHLY 1000 FEET ABOVE SURFACE IN THIS AREA THROUGH 06Z...WHICH BOTH NAM AND GFS SHOW THROUGH MUCH OF THE DAY FRIDAY. WITH STRONG SUBSIDENCE EXPECTED OVERNIGHT AND MOST OF FRIDAY...HIGH WIND WARNING WHICH WAS ISSUED EARLIER FOR NORTHEAST CORNER (6PM THIS EVENING THROUGH 6PM FRIDAY) STILL LOOKING ON TRACK. GRADIENT DECREASES SLIGHTLY AFTER 21Z FRIDAY...SO WARNING MAY NOT BE NEEDED INTO FRIDAY EVENING. FURTHER WEST...LESS WIND TO CONTEND WITH THOUGH COULD SEE GUSTS THIS EVENING AND AGAIN FRIDAY AFTERNOON. OTHERWISE...WITH DRIER SUBSIDENT AIRMASS IN PLACE FRIDAY...NOT EXPECTING ANY PRECIPITATION. TEMPERATURE AND THICKNESS PROGS AS WELL AS GUIDANCE SHOWING FRIDAY'S HIGHS REBOUNDING INTO THE 50S ACROSS PLAINS. FOR THE MOST PART THIS LOOKS ON TRACK...BUT WILL LOWER THE HIGHS A BIT ACROSS NORTHEAST CORNER WHERE THERE MAY STILL BE SOME SNOW ON GROUND. ALSO LOWERED HIGHS ALONG FOOTHILLS WHERE THERE WAS QUITE A BIT OF SNOW. .LONG TERM...WINDS WILL DECREASE EARLY FRIDAY EVENING AS SURFACE PRESSURE GRADIENT DECREASES WITH HIGH PRESSURE BUILDING ACROSS THE STATE. BY SATURDAY...AN UPPER LEVEL SPEED MAX WILL MOVE TOWARD THE COLORADO AND WYOMING BORDER WITH AN INCREASE IN MID LEVEL MOISTURE. THIS SHOULD BE ENOUGH TO KEEP THE CHANCE OF SHOWERS IN THE FORECAST IN THE HIGH COUNTRY...WHILE THE INCREASING WESTERLY DOWNSLOPE WARMING WILL PUSH TEMPERATURES ON THE PLAINS CLOSE TO 70F. SIMILAR WEATHER CONDITIONS CAN BE EXPECTED THROUGH SUNDAY...WITH JUST A SLIGHT CHANCE OF SHOWERS MOVING ACROSS THE PLAINS IN THE AFTERNOON AS INSTABILITY INCREASES. NONETHELESS...THE INSTABILITY DOES NOT LOOK IMPRESSIVE AT THIS TIME...BUT WE WILL KEEP A SLIGHT CHANCE OF THUNDER IN FOR NOW TO MAINTAIN CONSISTENCY. FOR MONDAY INTO TUESDAY...THE MEDIUM RANGE MODELS HAVE REASONABLE AGREEMENT OF AT LEAST A WEAK SHORT WAVE MOVING ACROSS COLORADO. IN ADDITION...THERE IS ALSO GOOD AGREEMENT OF A COLD FRONT DROPPING ACROSS THE PLAINS. THIS SHOULD SET THE STAGE FOR ANOTHER PRECIPITATION EVENT...WITH TEMPERATURES TURNING COLD ENOUGH BY TUESDAY MORNING TO MENTION A RAIN/SNOW MIX DOWN ONTO THE PLAINS. WE HAVE INCREASED THE PRECIP CHANCES SLIGHTLY BASED ON THIS AGREEMENT...AND ALSO LOWERED HIGH TEMPERATURES FOR TUESDAY. AFTER THAT SYSTEM...MODEL TIMING BECOMES MORE UNCERTAIN. WE WILL LEAN TOWARD A CHANCE OF SHOWERS EACH DAY ALONG WITH NEAR OR SLIGHTLY BELOW NORMAL TEMPERATURES WITH SOMEWHAT OF AN UNSETTLED WEATHER PATTERN PROJECTED. && .AVIATION...SNOW HAS COME TO AN END...NOT EXPECTING REDEVELOPMENT. LOW MVFR CEILINGS HAVE DISSIPATED...THOUGH SOME SCATTERED BASES AROUND 1000 TO 2000 FEET AGL STILL FLOATING AROUND. SHOULD SEE VFR CONDITIONS PREVAILING THOUGH FRIDAY AS DRIER AIR CONTINUES TO WORK INTO REGION. NORTHWEST DOWNSLOPE WINDS TO PREVAIL THROUGH FRIDAY... THOUGH THE STRONGEST WINDS WILL REMAIN EAST OF THE DENVER AREA.
