315 PM MDT SAT AUG 24 2002

STRONG CONVECTION JUST ABT READY TO MOVE OVER THE NE CORNER OF THE
STATE.  LOW LVL MSTR...STEEP LAPSE RATES AND DRIER AIR ALOFT ARE
COMBINING WITH OUTFLOW BOUNDARIES FM EARLIER NEB PANHANDLE
CONVECTION TO PRODUCE ISOLATED SEVERE STORMS WITH LARGE HAIL AND
PSBLY SOME TORNADOS.  TORNADO WATCH REMAINS IN EFFECT FOR THIS AREA
UNTIL 8 PM MDT.  THE CHANCE OF SCT THUNDERSTORMS EXTENDS ACRS THE
REST OF NE CO THRU THIS EVENING.  MOD SELY SFC WNDS ACRS NE CO HAVE
BROUGHT SFC DEWPTS INTO THE MID 50S WITH TEMPS INTO THE LOW 80S.
SFC BASED CAPES FM LAPS ARE AS HIGH AS 2200 J/KG.  OUTFLOW
BOUNDARIES CONTINUING TO MOVE SWWD WL PROBABLY BE THE FOCUSING
MECHANISM FOR ADDITIONAL THUNDERSTORM DEVELOPMENT WELL INTO THE
EVENING.  ALOFT...A 100+ KT JET IS ARCING ACROSS THE NRN BORDER OF
THE STATE AND WILL BE IN PLACE THRU 06Z.  OVR THE MTNS...A MUCH
DRIER AIRMASS IS IN PLACE AND ONLY A MINIMUM AMNT OF SHOWERS IS
EXPECTED THROUGH TONIGHT.

ON SUNDAY...SOME OF THE DRIER AIR WILL WORK ONTO THE PLAINS BUT THE
LATEST MESO-ETA STILL HANGS ONTO LOW LEVEL MSTR FM WASHINGTON COUNTY
NWD AND EWD.  THE WEAK UPR RDG OVR THE SWRN U.S. IS GOING TO BE SET
IN PLACE OVR THE NEXT FEW DAYS...SO THE GENERAL PATTERN OF AFTN
SHOWER ACTIVITY ON THE PLAINS WILL CONTINUE.  THE MTNS WL CONT TO BE
TOO DRY FOR SHOWER ACTIVITY...BUT THE WLY FLOW IS NOT GOING TO BE
STRONG ENOUGH TO FLUSH THE LOW LVL MSTR OUT OF OUR FCST AREA.  TEMPS
ARND THE DENVER AREA WILL CLIMB A FEW DEGREES WARMER...BUT FARTHER
EAST ON THE PLAINS WL BE PERSISTENT IN THEIR AFTN HIGHS.

THIS PATTERN SHOULD CONTINUE MUCH OF THE WEEK...ALTHOUGH AFTER
MONDAY IT IS HARD TO PINPOINT ANY PART OF THE PLAINS THAT HAVE A
HIGHER CHANCE OF SHOWERS THAN ANYWHERE ELSE.  INDICATIONS ARE THAT A
FRONT MOVE INTO THE AREA TUESDAY WHICH MAY BRING MSTR AND
INSTABILITY ALL THE WAY BACK TO THE FOOTHILLS.  LATER IN THE
WEEK...TEMPS MAY BE A FEW DEGS WARMER THAN TUES AND WED...WHICH WL
BE THE COOLEST DAYS OF THE WEEK.               KDRBY
