.DISCUSSION...
215 PM MDT THU MAY 8 2008

16Z WATER VAPOR IMAGERY INDICATED SHORT WAVE TROUGH UPSTREAM OF THE
AREA AND NEARING THE FOUR CORNERS AREA. AT THE SFC...COLD FRONT WAS
MOVING ACROSS THE NEB PANHANDLE AND NORTHERN COLORADO. DESPITE
CHILLY START TO THE MORNING...MOISTURE RETURN APPEARS WELL UNDERWAY
WITH LOWER 50 TDS ALREADY ENTERING SOUTHERN/CENTRAL CWA.

PRIMARY FORECAST CONCERNS WILL BE THUNDERSTORM CHANCES/SEVERE WX
TONIGHT AND TOMORROW.

TONIGHT...SHORT WAVE TROUGH WILL CONTINUE TO MOVE ACROSS THE AREA
AND EXPECT WIDESPREAD CONVECTION TO BE ONGOING AHEAD OF THE TROUGH
AND ALONG ADVANCING COLD FRONT. BASED ON CURRENT OBSERVATIONS AND
MODIFIED SOUNDINGS...LOOKS LIKE SUFFICIENT INSTABILITY AND SHEAR WILL
BE PRESENT FOR STRONG/SEVERE THUNDERSTORMS THROUGH THE EARLY
EVENING. SHEAR VECTORS STILL RUNNING ROUGHLY PARALLEL TO THE
FRONT...AND WITH LARGE SCALE FORCING FOR ASCENT WOULD EXPECT
THUNDERSTORMS TO FORM A SOLID LINE ALONG THE FRONT. CURRENT POP
FORECAST LOOKS REASONABLE...BUT WILL FINE TUNE AS CONVECTION
DEVELOPS THIS AFTERNOON. OTHER CONCERN FOR NIGHT WILL BE FOG
POTENTIAL. SURPRISINGLY BOTH NAM AND GFS INDICATING FAVORABLE
SOUNDINGS FOR FOG DEVELOPMENT OVERNIGHT. ONLY QUESTION IS IF WINDS
WILL WEAKEN QUICKLY ENOUGH BEHIND THE FRONT TO ALLOW ENOUGH
COOLING...BUT PATCHY FOG LOOKS POSSIBLE EARLY THIS MORNING.

TOMORROW-TOMORROW NIGHT...TONIGHTS COLD FRONT SHOULD RETREAT
NORTHWARD AS A WARM FRONT AS ANOTHER STRONG SHORT WAVE TROUGH
APPROACHES THE AREA. GFS AND NAM CONTINUE TO DISAGREE WITH
PLACEMENT/STRENGTH OF THIS FEATURE. GFS HAS BEEN CONSISTENT WITH
DEVELOPING AN AXIS OF WEAK INSTABILITY ALONG AND NORTH OF THE WARM
FRONT...AND CANADIAN SEEMS TO BE TRENDING IN THIS SAME DIRECTION.
MODEL DIFFERENCES CONTINUE THROUGH THE NIGHT AHEAD OF NEXT SHORT
WAVE TROUGH. NAM APPEARS SLIGHTLY FASTER WITH UPPER TROUGH AND COLD
FRONT...RESULTING IN FAIRLY STRONG FORCING AT H85 AS LLJ IMPINGES ON
COLD FRONT. GFS AND CANADIAN APPEAR TO TAKE THE SLOWER ROUTE...AND
BASED ON PAST PERFORMANCE WOULD TEND TO LEAN TOWARDS THE GFS. EVEN
USING SLOWER MODEL SOLUTIONS...AREA H85-H7 FRONTOGENESIS DOES BEGIN
TO OVERSPREAD THE AREA AFTER 06Z. ALTHOUGH THERE IS PLENTY OF
UNCERTAINTY IN EVOLUTION OF THIS SYSTEM...ENOUGH FORCING PRESENT
EVEN IN THE SLOWER MODELS TO UP POPS OVERNIGHT AND IF NAM FORECAST
VERIFIES WILL HAVE TO INCREASES CHANCES/AMOUNTS SIGNIFICANTLY.

SATURDAY-SATURDAY NIGHT...H5 TROUGH WILL SWEEP ACROSS THE AREA
DURING THE DAY...WITH DIV Q FIELDS INDICATING BEST WIDESPREAD
FORCING FOR ASCENT SWEEPING ACROSS THE CENTRAL AND NORTHERN CWA
DURING THE MORNING HOURS. AS MENTIONED BEFORE...LARGE SPREAD IN
MODEL SOLUTIONS KEEP CONFIDENCE LOW IN POST FRONTAL PRECIP
POTENTIAL...BUT WITH STEEP LAPSE RATES IN PLACE IN AHEAD OF TROUGH
AND STRONG FORCING...PRECIPITATION SEEMS REASONABLE. STABILITY
PROFILES STABILIZE QUICKLY AND AS FAST AS THE FRONTOGENESIS FORCING
MOVES THROUGH DO NOT ANTICIPATE A LOT OF PRECIPITATION. STRONG
FORCING FOR SUBSIDENCE OVERSPREADS THE AREA AROUND 00Z...BRINGING AN
END TO PRECIPITATION AND GRADUALLY CLEARING THE SKYS.

SUNDAY...COLD AND DRY HIGH PRESSURE WILL SETTLE OVER THE REGION
DURING THE MORNING HOURS LEADING TO A FAIRLY CHILLY START TO THE
DAY. ALTHOUGH HIGH SHIFTS TO THE EAST AND SFC TROUGH DEVELOPS OVER
THE WEST...COOL AND DRY SURFACE AIR WILL KEEP ATMOSPHERE STABLE
DURING PEAK HEATING.

IN THE EXTENDED...HIGH DEGREE OF UNCERTAINTY CONTINUES THROUGH THE
PERIOD AS MEDIUM RANGE MODELS CONTINUE TO JUMP AROUND QUITE A BIT
WITH SYNOPTIC SCALE FLOW ALOFT. GFS AND ECMWF HAVE PRETTY MUCH
SWAPPED SOLUTIONS WITH EACH OTHER...WITH ECMWF NOW MUCH MORE
PROGRESSIVE WITH ITS MID WEEK TROUGH AND GFS NOW MUCH SLOWER. ECMWF
LOOKS SIMILAR TO YESTERDAYS 12Z RUN...WHILE GFS MUCH DIFFERENT BUT
HARD TO SAY EITHER ONE HAS HAD GOOD RUN TO RUN CONSISTENCY.
CANADIAN...AT LEAST THROUGH 144 HOURS SEEMS TO FAVOR THE ECMWF
SOLUTION. 00/06Z ENS MEAN ALSO FAVORS THIS SOLUTION WITH THE MOST
CLUSTERING IN THE THE MORE PROGRESSIVE SOULTION...ALTHOUGH THERE
ARE SEVERAL MEMBERS IN THE SLOWER GFS CAMP. SEEMS LIKE A BULK OF
MODEL DATA LEANING MORE TOWARDS THE ECMWF SOLUTION SO WILL GENERALLY
TRY TO TREND FORECAST IN THIS DIRECTION.
