Area forecast discussion, Aug 10, 1:40 PM MST, 5 hours 56 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
240 PM MDT TUE AUG 10 2004

.DISCUSSION...ACTIVE NORTHWEST FLOW CONTINUES. FOR TONIGHT ANOTHER
SHORTWAVE CURRENTLY MOVING SOUTHEAST OUT OF THE NORTHERN PLAINS PER
WATER VAPOR IMAGERY WILL PROVIDE FORCING FOR ANOTHER ROUND OF SEVERE
STORMS ACROSS THE FORECAST AREA. LOW LEVEL CONVERGENCE/UPPER
DIVERGENCE COUPLET WILL PRODUCE A GOOD BULLSEYE OF OMEGA MOVES FROM
EASTERN COLORADO ACROSS THE REST OF THE FORECAST AREA DURING THE
EVENING. STORMS WILL FORM ALONG A STALLED FRONT/THETA E RIDGE IN
EASTERN COLORADO. CURRENT CAPE VALUES NEAR THESE BOUNDARIES ARE
AROUND 2400 J/KG. CAPE VALUES IN THE NORTHEAST FORECAST AREA ARE
MEAGER.  AT THE SURFACE...HIGH PRESSURE WILL BE OVER THE AREA WITH A
FRONT STALLED OUT IN A NORTHWEST TO SOUTHEAST ORIENTATION FROM
EASTERN COLORADO INTO WESTERN KANSAS. THIS WILL EFFECTIVELY SERVE AS
THE DIVIDING LINE FOR HIGHER POPS SOUTH OF THE FRONT AND LOWER
NORTH. PLAN TO GO LIKELY IN THE SOUTHWEST TONIGHT TAPERING TO LOW
SCATTERED POPS IN THE NORTHEAST. THIS PATTERN CONTINUES THROUGH
FRIDAY BUT LITTLE OR NO FORCING OR SHORTWAVES INDICATED BY ETA FOR
WEDNESDAY/THURSDAY. HOWEVER THE ETA IS HINTING AT THE IDEA OF STORMS
DEVELOPING ON MOUNTAINS AND MOVING SOUTHEAST JUST BRUSHING WESTERN
CHEYENNE COUNTY COLORADO AND GREELEY COUNTY KANSAS. THIS SEEMS
REASONABLE SO WILL KEEP CURRENT SLIGHT CHANCE THERE WEDNESDAY
AFTERNOON/EVENING. HOWEVER DO NOT SEE ANY FORCING FOR OVERNIGHT
ACTIVITY OVER THE REST OF THE FORECAST AREA SO WILL REMOVE
POPS/WEATHER FOR 06Z-12Z. A REPEAT OF THIS COULD HAPPEN AGAIN
THURSDAY AFTERNOON BUT DYNAMICS APPEAR TO BE FURTHER SOUTH SO WILL
LEAVE OUT POPS FOR NOW. ON FRIDAY BOTH THE GFS/ETA INDICATE ANOTHER
WAVE MOVING THROUGH BUT IT APPEARS TO AFFECT THE NORTHEAST FORECAST
AREA WHERE COOLER MORE STABLE AIR IS BEHIND THE FRONT SO WILL
DISCOUNT ANY WEAK FORCING IT PROVIDES. 850MB TEMPERATURES INDICATE A
SLIGHT WARMING TREND OF A FEW DEGREES OVER THE NEXT COUPLE OF DAYS.

DAYS 4-7...NORTHWEST FLOW CONTINUES THROUGH SUNDAY. TIMING OF WEAK
WAVES IN THE FLOW DIFFICULT THIS FAR OUT SO WILL LEAVE FORECAST DRY
UNTIL MONDAY. MONDAY/TUESDAY A 700MB TROUGH IS ADVERTISED TO MOVE
INTO THE ROCKIES AND PLAINS. FOR NOW WILL PLAY CONSERVATIVE SLIGHT
CHANCE POPS. MAX TEMPERATURES WILL BE IN THE 80S WITH LOWS NEAR
NORMAL AROUND 60.

EVENING SOUTH OF A LINE FROM YUMA COLORADO TO GOODLAND AND RUSSELL
