Tornado and Hail in Colorado, June 27, 2005

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
230 PM MDT MON JUN 27 2005

.SHORT TERM...LACK OF MID LEVEL MOISTURE TODAY COMPARED WITH
YESTERDAY SO CONSEQUENTLY NOTHING SO FAR AND MAY WELL NEVER GET ANY
STORMS THIS EVENING.  REMOVED ISOLATED POPS FROM SOUTHERN TWO THIRDS
OF AREA EARLIER.  CURRENT SATELLITE IMAGERY SHOWS SOME CU
DEVELOPMENT NEAR THE WY BORDER AT SOUTHERN END OF WHERE THERE IS
BETTER MID LEVEL MOISTURE.  WILL LIKELY GO AHEAD AND LEAVE THE
ISOLATED POPS OVER THE NORTHERN PORTIONS THOUGH MAY TRIM BACK TO
ZERO IF THINGS DONT DEVELOP ANY MORE IN THE NEXT HOUR OR SO.  THERE
IS ALSO AN AREA OF CU THAT HAS DEVELOPED ALONG A VERY WEAK
CONVERGENCE ZONE IN EASTERN WASHINGTON COUNTY AND THERE IS HIGHER
LOW LEVEL MOISTURE TO THE EAST SO THIS ACTIVITY COULD DEVELOP NORTH
INTO PHILLIPS AND SEDGWICK COUNTIES.  ADDITIONALLY DWFE MODELS AND
OUR LATEST MM5 LOCAL MODEL ALL SHOW STRONG DEVELOPMENT MAY OCCUR
OVER WESTERN NEBRASKA THIS EVENING AND SOME OF THIS COULD DRIFT INTO
THE NORTHEAST CORNER.  THIS ACTIVITY WILL LIKELY SEND SOME MOIST
OUTFLOW INTO THE NORTHEAST LATER TONIGHT AND THIS COULD ACT AS A
BOUNDARY FOR TOMORROWS ACTIVITY...ALTHO LATEST MODELS TEND TO DRIFT
THIS BOUNDARY FARTHER EAST AND THE ATMOSPHERE WILL LIKELY BE
CAPPED...SO WILL KEEP ANY THREAT ON THE PLAINS TO LATE IN THE DAY.
IN THE MOUNTAINS DO EXPECT CHANCE OF CONVECTION TO RETURN AS A PLUME
OF MIDLEVEL MOISTURE IS FORECAST TO MOVE NORTH FROM BOTH AZ AND FROM
MOISTURE NOW MOVING INTO SOUTHERN CA.  AGAIN LOOKS LIKE IT COULD BE
LATER IN THE AFTERNOON AND CURRENT POPS FOR THIS LOOK GOOD.

.LONG TERM...UPPER TROUGH AND ASSOCIATED SURFACE FRONT TO PASS
ACROSS AREA TUESDAY NIGHT AND WEDNESDAY. MODEL CROSS SECTIONS SHOW
LITTLE IN THE WAY OF ANY LOW LEVEL MOISTURE.  HOWEVER...INCREASING
LAPSE RATES ALONG WITH DIV-Q QG ASCENT WEDNESDAY AFTERNOON SUPPORT
SOME MAINLY HIGH BASED STORMS.  HOWEVER...BEST CHANCE FOR ANY
MEASURABLE PRECIPITATION APPEARS TO BE THURSDAY WHEN LOW LEVEL
MOISTURE INCREASES IN SOUTHEAST FLOW.  FAVORABLE LAPSE RATES AND
INCREASING VERTICAL WIND SHEAR WARRANT INCREASING THE POPS TO
SCATTERED ACROSS PLAINS.  COULD BE A FEW SEVERE STORMS AS FORECAST
CAPES DURING AFTERNOON RANGE FROM 1000-1500 J/JG.  ACTIVITY COULD
LINGER INTO THE EARLY MORNING HOURS FRIDAY AS DIV-Q QG ASCENT SHOWS
SOME LIFT LINGERING OVER AREA.  BY FRI AFTERNOON...SUBSIDENCE
BECOMES DOMINANT WHICH SHOULD PUT AN END TO ANY CONVECTION.  AS FOR
TEMPERATURES...LOWERED MAX GRIDS A BIT THURSDAY GIVEN SLIGHTLY LOWER
THICKNESS PROGS.

FROM SATURDAY THROUGH MONDAY...LOOKS WARM AND DRY AS UPPER LEVEL
RIDGE BUILDS OVER REGION.  COULD BE SOME FIRE WEATHER CONCERNS FOR
THE WEEKEND AS IT APPEARS THAT AFTERNOON HUMIDITY READINGS COULD HIT
SINGLE DIGITS.  GFS HINTS AT A FRONT MOVING INTO NORTHEAST COLORADO
LATE SUNDAY WHICH COULD PROVIDE FOR SOME CONVECTION MONDAY IF SURFACE
WINDS BECOME SOUTHEAST.  WILL KEEP THINGS DRY FOR NOW...AND WAIT
FOR LATER RUNS TO COMPOSE A CLEARER PICTURE.

.BOU...NONE.
