Area forecast discussion, Jun 18, 3:41 PM CDT, 1 hour 4 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
341 PM CDT THU JUN 18 2009

.DISCUSSION...

DAYS 1-2...

THUNDERSTORM CHANCES ARE THE MAIN FORECAST CHALLENGE.

UA ANALYSIS AND WATER VAPOR IMAGERY SHOW A LONGWAVE TROUGH OVER
WESTERN NORTH AMERICA. TO THE EAST OF THE TROUGH A MOIST TROPICAL
FEED WAS EVIDENT IN THE WATER VAPOR IMAGERY FROM THE TROPICS INTO
THE CENTRAL HIGH PLAINS. WEAK DISTURBANCES CONTINUE TO RIDE UP
INTO THE PLAINS ON THE EAST SIDE OF THE UPPER TROUGH. AT THE SURFACE
A DRYLINE WAS EVIDENT IN THE ANALYSIS FROM THE WEST TEXAS PANHANDLE
INTO SOUTHWEST KANSAS. THE SPC MESO ANALYSIS PAGE SHOWED SOME SURFACE
CONVERGENCE ALONG THE DRYLINE. NOT MUCH CONVECTION ALONG THE DRYLINE
SO FAR THIS AFTERNOON AS THE NEXT UPPER DISTURBANCE IN THE FLOW
WAS JUST COMING ACROSS THE RIO GRANDE. THERE WAS A 90 KNOT JET AT
250 MB OVER THE EASTERN SLOPES THIS MORNING WITH THE RIGHT
ENTRANCE REGION OVER THE CENTRAL HIGH PLAINS. COULD BE ENOUGH
CONVERGENCE TO WORK WITH THIS UVV TO GET A FEW STORMS TO FIRE
ALONG THE DRYLINE THIS AFTERNOON AND EVENING. STORMS SHOULD
DIMINISH AFTER WE LOSE HEATING BUT A FEW STORMS COULD LINGER
ACROSS THE CENTRAL HIGH PLAINS TONIGHT AS THE UPPER DISTURBANCE
APPROACHES.

ON FRIDAY THE UPPER WAVE SHEARS OUT WITH THE NORTHERN PORTION
HEADING INTO THE NORTHERN PLAINS. THE MODELS SHOW THE SURFACE
FRONT ASSOCIATED WITH THIS HEADING SOUTH ACROSS WESTERN KANSAS
DURING THE DAY AND BECOMING STATIONARY OVER THE SOUTHERN CWA
FRIDAY EVENING. THE NAM SHOWS THE AREA CONTINUING UNDER THE RIGHT
ENTRANCE REGION OF THE UPPER JET. EXPECT THAT WE WILL BE SEEING
SOME WIDELY SCATTERED STORMS ALONG THE FRONT AND INCREASING AS THE
BOUNDARY SLIDES SOUTH AND DAYTIME HEATING MAXIMIZES.

THUNDERSTORM CHANCES WILL CONTINUE INTO FRIDAY NIGHT AND INCREASE
ON SATURDAY AS THE REMAINS OF THE UPPER TROUGH OVER BAJA
CALIFORNIA GET KICKED OUT TO THE NORTHEAST ACROSS THE PLAINS. HAVE
CONTINUE THE HIGH CHANCE TO LIKELY POPS AND INCREASED QPF VALUES
SOMEWHAT GIVEN THE MOIST TROPICAL FEED. GERARD

DAYS 3-7...

THE UPPER PATTERN WILL CONTINUE TO TRANSITION TO A WESTERN TROUGH
WITH INCREASING NORTHERN PLAINS  SHORTWAVE ACTIVITY, AND A
SUBTROPICAL HIGH PRESSURE ALOFT RETROGRADING INTO THE LOWER
MISSISSIPPI VALLEY AND SOUTHERN-CENTRAL GREAT PLAINS.

BY SATURDAY ONGOING RAIN OR RAIN WITH EMBEDDED ROUNDS OF
THUNDERSTORMS ARE PROBABLE AS STRONG 850-700 MB MOISTURE TRANSPORT
SIGNAL IN ALL THE MODELS CONTINUES ALONG WITH JET ENERGY ALOFT AT 300
MB ALLOWS UPPER DIVERGENCE. WITH PRECIPITATION AND CLOUDS EXPECTED
SATURDAY, HAVE TRIMMED HIGHS BACK A BIT TO AROUND OR BELOW THE
COOLER MOS GUIDANCE. BY SUNDAY INTO MONDAY TEMPERATURES ALOFT WILL
INCREASE WHICH SHOULD DIMINISH PRECIPITATION CHANCES UNTIL A FRONT
FROM THE NORTHERN PLAINS BEGINS TO SAG SOUTHWARD TOWARD TUESDAY AND
WEDNESDAY (DAY 7). AFTER THIS WEEKEND TEMPERATURES WILL AGAIN WARM
INTO THE MID 90S TO UPPER 90S, AND MONDAY MAY BE PERHAPS THE WARMEST
DAY IN THE FORECAST.

&&

AVIATION...

ATMOSPHERE SETUPS THIS EVENING IN MUCH THE SAME PATTERN AS 24 HOURS
AGO, WITH INCREASING INSTABILITY LATE IN THE AFTERNOON AND A CHANCE
FOR A FEW STRONG TO SEVERE THUNDERSTORM TO PRODUCE OUTFLOW ACROSS
SOUTHWEST KANSAS. HAVE INCLUDED VCTS TO TERMINALS GENERALLY FORM
AROUND 00 TO 02 UTC AND WILL MONITOR TRENDS. AS THUNDERSTORMS
DECREASE DIURNALLY AND CLOD FRONT SHOULD SHIFT INTO THE FORECAST
AREA EARLY FRIDAY SHIFTING WINDS TO A NORTHWEST DIRECTION.
CONVECTIVE CHANCES WILL DECREASE INTO FRIDAY AFTERNOON AS DRIER AIR
WORKS INTO WESTERN KANSAS, THUS MANLY VFR CONDITIONS ARE ANTICIPATED
FOR FRIDAY AT THIS TIME. RUSSELL
