AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
1148 PM CDT THU APR 18 2013

...UPDATED FOR AVIATION...

.SHORT TERM...(THIS EVENING THROUGH FRIDAY)
ISSUED AT 334 PM CDT THU APR 18 2013

AS OF 20Z...THE SURFACE LOW ASSOCIATED WITH YESTERDAY'S STORM SYSTEM
WAS SITUATED OVER EASTERN IOWA WITH A STRONG PRESSURE GRADIENT IN
PLACE ON THE WEST SIDE OF THE SYSTEM. THIS PRESSURE GRADIENT BROUGHT
GUSTY NORTHWESTERLY WINDS TO THE FORECAST AREA THIS AFTERNOON AND
WILL PERSIST INTO THE EVENING HOURS. THE ASSOCIATED UPPER LEVEL
TROUGH WAS POSITIONED OVER THE NORTHERN AND CENTRAL PLAINS...AND
WILL CONTINUE TO LIFT NORTHEASTWARD TOWARD THE GREAT LAKES REGION
TONIGHT INTO FRIDAY. AS THIS WAVE LIFTED TO THE NORTH TODAY...LIGHT SNOW
WAS BEING REPORTED ACROSS SOUTHERN NEBRASKA AND CLIPPED PORTIONS OF
EXTREME NORTH CENTRAL KANSAS. MOST OF THIS LIGHT PRECIPITATION HAD
LIFTED NORTH OF THE CWA BY EARLY AFTERNOON...HOWEVER A FEW
FLURRIES ARE STILL POSSIBLE THROUGH THE REMAINDER OF THE
AFTERNOON. AS THIS UPPER LEVEL TROUGH SHIFTS EASTWARD AND STRONG
NORTHWESTERLY FLOW PERSISTS OVER THE NORTHERN AND CENTRAL
PLAINS...MUCH COLDER AIR WILL BE ADVECTED INTO THE REGION THIS
EVENING. SURFACE WINDS WILL DIMINISH SOME OVERNIGHT WITH CLOUDS
GRADUALLY CLEARING OUT THROUGH FRIDAY MORNING...SO EXPECT
OVERNIGHT LOWS TO PLUMMET INTO THE MIDDLE 20S TO LOWER 30S. AS A
RESULT...A FREEZE WARNING IS IN EFFECT FOR THE ENTIRE FORECAST
AREA FOR TONIGHT.

HIGH PRESSURE WILL BEGIN TO SPILL SOUTH ACROSS THE NORTHERN AND
CENTRAL PLAINS ON FRIDAY WITH SKIES BECOMING MOSTLY SUNNY THROUGH
THE DAY. DESPITE THE BREEZY WEST NORTHWESTERLY WINDS...THE SUNNY
SKIES SHOULD HELP TEMPERATURES PEAK INTO THE LOW/MID 50S.
HOWEVER...THESE CONDITIONS ARE AT LEAST 10F DEGREES BELOW THE
SEASONAL NORMALS...WHICH ARE SUPPOSED TO BE AROUND THE MID/UPPER
60S.

HENNECKE

.LONG TERM...(FRIDAY NIGHT THROUGH THURSDAY)
ISSUED AT 334 PM CDT THU APR 18 2013

SATURDAY THROUGH SUNDAY WILL BE MAINLY DRY. THE FORECAST FOCUS IS
INITIALLY ON TEMPERATURES AND SUB-FREEZING POTENTIAL...AND THEN ON
LOW END PRECIP CHANCES WITH A WEAK SHORT WAVE PASSAGE. A STRONGER
STORM SYSTEM THEN IMPACTS THE AREA MONDAY INTO TUESDAY WITH
ANOTHER SHOT OF RATHER COLD AIR.

SURFACE HIGH PRESSURE WILL CROSS THE FORECAST AREA FRIDAY NIGHT AND
BE LOCATED IN EASTERN MISSOURI BY SATURDAY MORNING. GIVEN THE TIMING
OF THE SURFACE HIGH...EXPECT THE BOUNDARY LAYER TO DECOUPLE QUITE
NICELY ESPECIALLY IN EASTERN KANSAS WITH WINDS BECOMING VERY LIGHT.
CLOUDS SHOULD ALSO HOLD OFF...ESPECIALLY EAST...UNTIL NEAR SUNRISE
WHEN MID LEVEL MOISTURE BUILDS IN. THIS SHOULD ALLOW TEMPS TO DROP
OFF QUITE NICELY WITH THE MAIN UNCERTAINTY LYING IN WHETHER CLOUD
COVER BUILDS IN EARLIER OR SOUTHERLY RETURN FLOW MIXES THE BOUNDARY
LAYER EARLIER IN THE NIGHT. EITHER OF THESE SCENARIOS WOULD LEAD TO
WARMER LOWS. AT THIS TIME...SUSPECT SUB FREEZING TEMPS AT LEAST IN
NORTHEAST KANSAS WITH AT LEAST SOME POTENTIAL FOR THIS IN THE WHOLE
AREA IF THE SITUATION PLAYS OUT FAVORABLY FOR COLD TEMPS. THE RETURN
FLOW WILL INCREASE NICELY FOR SATURDAY INTO SUNDAY IN ADVANCE OF A
PAIR OF UPPER TROUGHS. THIS WILL BRING WARM ADVECTION FOR THE
WEEKEND WITH HIGHS EXPECTED TO CLIMB INTO THE 60S. THE FIRST WEAK
TROUGH WILL MOVE OVER THE PLAINS ON SUNDAY WITH SOME SLIGHT CHANCES
FOR SHOWERS AND THUNDERSTORMS LATE SATURDAY NIGHT INTO SUNDAY NIGHT.
THESE CHANCES ARE MAINLY DRIVEN BY MODERATE UPPER LEVEL FORCING AND
WEAK INSTABILITY...BUT ARE MITIGATED BY WHAT SHOULD BE LACKING
BOUNDARY LAYER MOISTURE PROFILES.

A MORE SIGNIFICANT UPPER TROUGH IS FORECAST WITH FAIRLY STRONG MODEL
CONFIDENCE TO IMPACT THE AREA FROM MONDAY INTO TUESDAY. THE MAIN
TROUGH WILL HAVE A POSITIVE TILT WHILE LEAD SHORT WAVES EJECT IN
ADVANCE OF THE MAIN TROUGH. CURRENT INDICATIONS ARE THAT MOIST
SOUTHERLY FLOW WILL BE IN PLACE OVER THE AREA FOR A GOOD PART OF
MONDAY BEFORE ONE OF THE LEAD SHORT WAVES PUSHES A COLD FRONTAL
SURGE WELL INTO SOUTHEAST KANSAS MONDAY EVENING. EXPECT
THUNDERSTORMS ALONG AND AHEAD OF THIS FRONT...AND PERHAPS SOME
ELEVATED STORMS BEHIND THE FRONT. INSTABILITY APPEARS MEAGER AT THIS
TIME OWING TO PLENTY OF CLOUD COVER AND LIMITED TEMPERATURES. THE
COLD FRONT WILL BE QUITE STRONG...WITH SUB FREEZING 850 TEMPS
OVERSPREADING THE AREA IN ITS WAKE...AND ONCE AGAIN LIGHT SNOW
APPEARS POSSIBLE IN THE COLDER AREAS WITH THE BEST CHANCES IN NORTH
CENTRAL KANSAS. WILL THEN SEE FREEZING TEMPERATURES POSSIBLE ONCE
AGAIN ON WEDNESDAY MORNING AS THIS STORM SYSTEM CLEARS THE AREA.
COLDER THAN NORMAL TEMPS PERSIST THROUGH THE REMAINDER OF THE
FORECAST WITH A SLOW WARMING TREND.

BIT TOWARDS SUNRISE BUT WILL PICK UP AGAIN DURING THE MID MORNING
