Area forecast discussion, Jun 19, 3:48 PM CDT, 37 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
348 PM CDT THU JUN 19 2008

.DISCUSSION...

DAYS 1-2...

THE CURRENT PATTERN HAS BEEN VERY DIFFICULT TO FCST GIVEN ALL
THE MESOSCALE SYSTEMS THAT THE MODELS DO NOT CAPTURE. THIS
WILL CONTINUE FOR THE NEXT SEVERAL DAYS SINCE WE WILL REMAIN NEAR
THE SOUTHERN EDGE OF THE WESTERLIES. CLIMATOLOGICALLY, MID JUNE
INTO EARLY JULY IS THE MOST FAVORED TIME OF THE YEAR FOR THIS
PATTERN SINCE SFC BASED INSTABILITY IS USUALLY TAKEN FOR GRANTED AND
OUR FCST AREA TENDS TO BE LOCATED ALONG THE SOUTHERN PERIPHERY OF
THE WESTERLIES.

WESTERN KANSAS WAS IN THE EXIT REGION OF AN UPPER JET STREAK AGAIN
TODAY. STORMS WERE ONGOING AND POPS FOR THIS EVENING WERE HEAVILY
INFLUENCED BY CURRENT RADAR TRENDS.

THE MODELS PUSH CONVECTION DOWN THE PLAINS TONIGHT AND STABILIZE
WESTERN KANSAS. SFC AND ELEVATED CAPES SHOULD BE LOWER ON THURSDAY
DESPITE FAVORABLE JET DYNAMICS(NOSE OF 70KT JET IN WESTERN KS).
SO TEMPS SHOULD RECOVER INTO THE 80S. GIVEN THE HIGHER STABILITY
OVER THE PLAINS, THE BEST CHANCE OF STORM INITIATION MAY BE ON THE
FRONT RANGE. BUT SOME OF THESE STORMS COULD STILL DRIFT INTO WESTERN
KANSAS IN THE LATE AFTERNOON AND EVENING.

DAYS 3-7...

THE LOW WILL AMPLIFY BY SATURDAY EVENING WITH MORE OF A NNW OR NW MID
LEVEL FLOW PATTERN. ANY STORMS DEVELOPING NEAR THE TERRAIN FEATURES
TO OUR WEST SATURDAY AFTERNOON SHOULD TEND TO STAY WEST OF OUR AREA. OUR
WESTERN COUNTIES HAVE THE BEST CHANCE OF STORMS SATURDAY NIGHT AS THE
STORMS MOVE ONTO THE LOWER TERRAIN.

UPPER RIDGING SHOULD BE SHORT LIVED SUNDAY AS THE ECMWF CONTINUES
TO SHOW AN MCS ACROSS MUCH OF THE CENTRAL PLAINS MONDAY INTO
MONDAY NIGHT AS A WEAK IMPULSE CROSSES THE AREA. POPS WERE RAISED
TO 40 PERCENT FOR THIS SYSTEM.

THE ECMWF HAS BACKED OFF ON THE LARGE TROUGH OVER THE PACIFIC NW
FOR JUNE 26-28. BUT THE GFS AND ECMWF CONTINUE TO SHOW SW KS IN
A FAVORED AREA FOR STORM CLUSTERS--NEAR THE SOUTHERN PERIPHERY OF THE
WESTERLIES.

LARGE HAIL AND DAMAGING WINDS WILL BE THE PRIMARY
THREAT...ALTHOUGH TORNADOES ARE NOT COMPLETELY OUT OF THE
QUESTION. DURING THE OVERNIGHT HOURS...THE ACTIVITY WILL MERGE
INTO A COMPLEX OF THUNDERSTORMS...BRINGING STRONG WINDS AND HEAVY
RAIN.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

STORMS MOVING OFF THE HIGH TERRAIN OF EASTERN COLORADO INTO FAR
WESTERN KANSAS COULD BRING A THREAT FOR HAIL AND HIGH WINDS FRIDAY
AFTERNOON AND NIGHT...MAINLY WEST OF A LIBERAL TO SCOTT CITY LINE.
