Severe Thunderstorm Warning 32, NWS Dodge City, KS

AREA FORECAST DISCUSSION...FINAL DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
259 AM CDT WED MAY 14 2003

DAYS 1-2...

UPPER LOW WAS LOCATED JUST OFF THE CALIFORNIA COAST THIS MORNING.
NORTHERN STREAM WESTERLIES WERE BUILDING SOUTHWARD IN THE EASTERN
PACIFIC AND WILL HELP KICK THE UPPER LOW EASTWARD OVER THE NEXT 72
HOURS. ALTHOUGH THE WARM SECTOR AND ASSOCIATED SEVERE, SURFACE BASED
CONVECTION WILL STAY TO THE SOUTH IN WEST TX, STRONG WARM ADVECTION
NORTHEAST OF THE UPPER SYSTEM WILL LEAD TO WIDESPREAD SHOWER AND
THUNDERSTORM ACTIVITY ACROSS WESTERN KANSAS. WE IGNORED THE 00Z ETA
SINCE THIS MODEL PERFORMS POORLY UNTIL SYSTEMS COME ONSHORE. THE ETA
SHOULD HAVE A MUCH BETTER HANDLE ON THE SYSTEM BY 00Z THU. THE
ECMWF/UKMET/AVN HAVE BEEN FAIRLY CONSISTENT WITH THIS SYSTEM OVER
THE PAST SEVERAL RUNS. HAVE DECIDED TO INCREASE POPS TO 90% FOR
THURSDAY NIGHT ACROSS MUCH OF THE FORECAST AREA EXCEPT FOR THE NORTH
WHERE 40-60% POPS WILL BE MAINTAINED. WILL ALSO MENTION LOCALLY
HEAVY RAINS.

TEMPERATURES WILL BE HELD DOWN THURSDAY DUE TO CLOUDS AND
PRECIPITATION, ESPECIALLY IN THE WEST WHERE IT WILL BE SOCKED IN ALL
DAY. LOWERED MAXES INTO THE 60S FAR WEST WITH WARMER 70S EAST.

DAYS 3-7...

THE ONLY REAL CHANGE MADE TO THE EXTENDED GRIDS TONIGHT WILL BE TO
INCREASE POPS FRIDAY MORNING AND SMOOTH THE FIELDS FOR BETTER
TRANSITION FROM THURSDAY NIGHT.  THE GFS AND ECMWF MOVE OUT THE
UPPER LOW FROM THE TX/OK PANHANDLES EASTWARD VERY SLOWLY.  THE
OPERATIONAL CANADIAN IS SOMEWHAT FASTER, BUT WITH SOME OF ITS
ENSEMBLE MEMBERS KEEPING THE WAVE OVER THE PLAINS, AM MORE INCLINED
TO GO WITH A GFS/ECMWF SOLUTION.  THUS, BELIEVE THAT THERE IS A GOOD
CHANCE THAT PRECIP WILL LINGER THROUGH FRIDAY MORNING, TAPERING OFF
FROM WEST TO EAST DURING THE AFTERNOON AND INTO SATURDAY NIGHT.
ALSO DECREASED FRIDAYS HIGHS DUE TO THE CLOUDS AND PRECIP.
OTHERWISE, LEFT THE REST OF THE EXTENDED ALONE.
