...CORRECTED TO RED FLAG WARNING HEADLING BELOW...

.SHORT TERM...SHORTWAVE WITH QUITE A BIT OF LIGHTNING CURRENTLY
MOVING INTO NORTHWEST COLORADO...WITH TAIL END ACROS CENTRAL UTAH.
DECENT LIFT AHEAD OF TROUGH...MAINLY OVER SOUTHEAST WYOMING. LAPS
SURFACE ANALYSIS SHOWING CAPES ROUGHLY 1000-2000 J/KG NEAR NORTHERN

30 KTS EXIST ALONG WITH DEWPOINTS IN THE LOW TEENS. RED FLAG WARNING
STILL IN EFFECT THERE THROUGH 03Z. CONDITIONS MARGINAL IN PARK AND
SUMMIT COUNTIES...BUT THERE IS SOME HIGH BASED CONVECTION WHICH
COULD HELP THINGS A BIT THERE. MODELS SHOW SHORTWAVE MOVING ACROSS
NORTHERN COLORADO THROUGH THE EVENING...SO WILL KEEP THE HIGHER POPS
THERE WITH LESS FURTHER SOUTH. CROSS SECTIONS SHOW MOISTURE
DECREASING AFTER MIDNIGHT AS SUBSIDENCE MOVES IN BEHIND WAVE. COULD
SEE SOME LIGHT RAIN SHOWERS LINGERING AFTER MIDNIGHT. LAPSE RATES
DECREASE OVERNIGHT...SO WILL NOT MENTION THUNDER. ALSO...DESPITE
COOLING...WILL KEEP PRECIP AS LIQUID OVER MOUNTAINS. BOUNDARY LAYER
WIND AND MOISTURE PROGS SUGGEST POTENTIAL FOR LOW CLOUDS AND FOG
ACROSS PLAINS BETWEEN 09Z AND 15Z. WILL INCLUDE PATCHY FOG IN THE
ZONES. GUIDANCE SUGGESTS LOW CLOUDS AND POTENTIAL FOG AS FAR WEST AS
THE FOOTHILLS. WILL ONLY INCLUDE URBAN CORRIDOR FOR NOW. ON
FRIDAY...SOUTHWEST FLOW ALOFT CONTINUES AS ANOTHER SHORTWAVE ALONG
WITH A BATCH MOVES ACROSS COLORADO DURING THE AFTERNOON. MOST OF THE
ASCENT STAYS WEST OF CFWA...THOUGH SOME SPILLS ACROSS MOUNTAINS.
WITH LAPSE RATES INCREASING TO AROUND 8 C/KM DURING THE AFTERNOON...
WILL KEEP THE SLIGHT CHANCE FOR STORMS GOING ACROSS MOST OF AREA.
THINGS DO LOOK A BIT STABLE OVER FAR NORTHEAST CORNER...NO POPS
THERE. TEMPERATURE AND THICKNESS PROGS SUGGEST HIGHS IN THE 70S
ACROSS PLAINS...WITH NAM GUIDANCE SHOWING MID 70S AT DENVER. GFS
GUIDANCE A BIT WARMER AT DENVER WITH A HIGH OF 80 DEGREES. CURRENT
TEMPERATURE GRIDS ARE CLOSER TO THE GFS GUIDANCE...AND LOOKS MORE
RESONABLE.

.LONG TERM...THE SOUTHWESTERLY FLOW ALOFT WILL REMAIN IN PLACE
THROUGH THE WEEKEND. AS MID LEVEL SUBSIDENCE CONTINUES TO LIFT NORTH
FRIDAY AFTERNOON...ISOLATED TO SCATTERED TSTMS MAY DEVELOP.  NAM12
SOUNDINGS INDICATE THE BEST INSTABILITY WILL BE EAST AND SOUTHEAST
OF DENVER ALONG THE PALMER DIVIDE.  FCST CAPES AROUND 1900 J/KG OVER
THAT AREA...WITH LESSER CAPES OF AROUND 800 J/KG ALONG THE NRN
BORDER.  SHEAR SUFFICIENT ENOUGH TO PRODUCE A FEW SEVERE CELLS IF
THE STORMS DEVELOP.  WILL CONTINUE WITH 30 PERCENT COVERAGE EAST AND
SOUTH OF DENVER WITH LESSER POPS ELSEWHERE.  TEMPERATURES NEAR
NORMAL ON SATURDAY...WITH A WEAK SHORT WAVE RIDGE OVER THE AREA.
ENOUGH MOISTURE EMBEDDED THE THE FLOW WILL ALLOW FOR A SLIGHT CHANCE
OF AFTERNOON AND EVENING THUNDERSTORMS OVER THE WEEKEND.  MID LEVEL
QG ASCENT WILL BEGIN TO SPREAD ACROSS WRN CO SUNDAY NIGHT AS AN
UPPER LEVEL TROF OVER ERN NV/UT MOVES TO THE EAST-NORTHWEST.  WL GO
WITH CHC POPS IN THE MTNS SUNDAY NIGHT AND MONDAY...WITH SLGT CHC
POPS ELSEWHERE.  TEMPERATURES WARM UP SLIGHTLY ON SUNDAY AHEAD OF
THE NEXT SYSTEM.  THE MAIN FORCING WITH THE SYSTEM WILL BE IN THE
UPPER LEVELS WITH QG ASCENT AOA 700 MB.  SFC LOW NOT VERY WELL
ORGANIZED AT THIS POINT AND TOO FAR NORTH TO ALLOW FOR GOOD UPSLOPE
FLOW TO DEVELOP MONDAY. THE UPPER TROF IS PROGGED TO MOVE EAST
MONDAY NIGHT WITH A NORTHWESTERLY FLOW DEVELOPING AT THAT TIME. WILL
NOT ALTER TEMPERATURE GRIDS TOO MUCH WITH MONDAY THE COOLEST DAY OF
THE WEEK.  WL GO WITH A PERSISTENT SLIGHT CHC OF AFTN/EVNG TSTMS FOR
THE REST OF THE PERIOD.  SHOULD SEE TEMPERATURES RETURN TO ABOVE
NORMAL BY THURSDAY OF NEXT WEEK.  STILL SOME DISCREPANCIES REGARDING
THE TIMING AND STRENGTH OF THE NEXT TROF.

SOUTHEAST WINDS WILL WEAKEN DURING THE EVENING...BECOMING LIGHT
SOUTHWEST TO WEST BY 05Z. CHANCE OF MVFR CONDITIONS WITH THE
DEVELOPMENT OF STRATUS AND POSSIBLE FOG. WILL KEEP THE MVFR
CONDITONS AS A TEMPO GROUP BETWEEN 11Z AND 15Z. OTHERWISE...A SLIGHT
CHANCE OF THUNDERSTORMS AFTER 18Z AS A WEAK DISTURBANCE MOVES ACROSS
THE REGION. MAIN THREAT WILL BE GUSTY OUTFLOW WINDS AND LIGHT RAIN.
VFR CONDITIONS TO PREVAIL...WITH POSSIBLE CEILINGS AROUND 6000 FEET
AGL.

&&

.HYDROLOGY...NO MAJOR IMPACTS EXPECTED FOR THE BURN AREAS TONIGHT OR
FRIDAY. THERE IS A SLIGHT CHANCE OF THUNDERSTORMS THIS EVENING AND
AGAIN FRIDAY AFTERNOON. BUT THE STORM MOTION SHOULD BE FAST ENOUGH
TO KEEP CONCERNS LOW. RAINFALL AMOUNTS SHOULD BE AROUND A TENTH OF
AN INCH.

TEMPERATURES NEAR AVERAGE ARE EXPECTED THROUGH SUNDAY. BELOW AVERAGE
TEMPERATURES SUNDAY NIGHT THROUGH WEDNESDAY WILL SLOW THE MELTING OF
THE MOUNTAIN SNOWPACK. SEVERAL RIVERS IN JACKSON COUNTY ARE OVER
BANKFULL. THE COLORADO RIVER IS FORECAST TO RISE AS RESERVOIR
RELEASES INCREASE DUE TO MOUNTAIN SNOWMELT. ELSEWHERE IN NORTH
CENTRAL COLORADO...OVERALL IMPACTS FROM MOUNTAIN SNOWMELT RUNOFF ARE
EXPECTED TO BE LOW. HOWEVER...WITH THE INCREASED CHANCE FOR
SCATTERED SHOWERS EARLY NEXT WEEK THERE IS STILL A SLIGHT RISK FOR
EVEN HIGHER FLOWS.

FLOOD ADVISORIES ARE IN EFFECT FOR RIVERS IN JACKSON COUNTY AND THE
COLORADO RIVER IN NORTHERN GRAND COUNTY IN NORTH CENTRAL COLORADO.
