AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
1227 PM CDT MON APR 9 2012

.AVIATION...18Z KGRI TAF. VFR CONDITIONS EXPECTED THRU THE PERIOD.
HIGH PRESSURE WILL CONTINUE TO BE THE DOMINANT FEATURE SO ONLY A
FEW MID AND HIGH CLOUDS EXPECTED.

&&

PREV DISCUSSION... /ISSUED 502 AM CDT MON APR 9 2012/

SHORT TERM...TODAY THROUGH WEDNESDAY NIGHT

THE UPPER LEVEL PATTERN IS STRAIGHT-FORWARD AS A HIGHLY AMPLIFIED
RIDGE OVER THE ROCKIES EDGES EAST OVER THE COURSE OF THE SHORT TERM
FORECAST...AND RIDGE AXIS WILL EVENTUALLY CROSS THE CWA LATE
WEDNESDAY NIGHT.

A SURFACE COLD FRONT CONTINUES TO SAG SOUTH AND HAS ALMOST COMPLETELY
CLEARED THE CWA...EXCEPT FAR SOUTH/SOUTHEAST AREAS WITHIN NORTH
CENTRAL KANSAS. THIS BOUNDARY SHOULD CONTINUE TO SAG SOUTH OF THE
CWA TODAY. BASED ON VERIFICATION DATA...I ACTUALLY BUMPED UP
TEMPERATURES A BIT FOR THIS AFTERNOON FOR CENTRAL AND SOUTHERN AREAS
OF THE CWA. WE SHOULD HAVE PLENTY OF SUN TODAY WITH LIGHT
EAST/NORTHEAST WIND. RELATIVE HUMIDITY LEVELS IN THE NORTHEASTERN
CWA WILL DROP DOWN TO AROUND 20 PERCENT...BUT WITH THE ANTICIPATED
LIGHT WIND...IT APPEARS THAT FIRE WEATHER CONCERNS WILL NOT BE A
HUGE ISSUE TODAY. FREEZING TEMPERATURES SHOULD ONCE AGAIN BE AN
ISSUE IN THE NORTHERN CWA TONIGHT AS IT HAS FOR THE PAST COUPLE OF
NIGHTS. COOLER 850 MB TEMPERATURES ALONG WITH INCREASING SKY COVER
WILL COOL TEMPERATURES DOWN TUESDAY. INCREASED ISENTROPIC LIFT WILL
BRING IN CONSIDERABLE CLOUDINESS BY LATE TUESDAY NIGHT...WITH SOME
FOG POSSIBLE WITH THE INTRODUCTION OF STRATUS. SOUNDINGS SUGGEST TOO
MUCH DRY AIR IN THE BOUNDARY LAYER FOR TUESDAY NIGHT...EXCEPT THERE
COULD PERHAPS BE SOME LIGHT PRECIPITATION IN THE FAR SOUTH CWA BY
VERY LATE TUESDAY NIGHT. RAIN COULD SPREAD FARTHER NORTH ON
WEDNESDAY...BUT WHEN THE LOW-LEVEL JET KICKS IN WEDNESDAY
NIGHT...THERE WILL BE A GOOD CHANCE OF RAIN. MUCAPES ARE ALMOST
NON-EXISTENT UNTIL WEDNESDAY NIGHT ALSO.

LONG TERM...THURSDAY THROUGH SUNDAY.

THE LONG TERM PERIOD LOOKS TO BE QUITE AN ACTIVE WEATHER PATTERN
WITH SEVERAL BURSTS OF PRECIPITATION AND EVEN POTENTIAL FOR SEVERE
WEATHER. USING THE FORECAST FUNNEL...THERE APPEARS TO BE AT LEAST 7
UPPER LEVEL TROUGHS DEVELOPING AROUND THE NORTHERN HEMISPHERE BY
THURSDAY MORNING INDICATING A VERY ACTIVE PATTERN AND MOSTLY
MERIDIONAL FLOW. GLANCING AT THE CONUS...ONE UPPER LEVEL TROUGH
BEGINS TO PUSH EASTWARD ACROSS THE EAST COAST. A SECOND TROUGH
BEGINS TO DEEPENING ACROSS THE WEST COAST...WHILE A PORTION OF THE
TROUGH ENERGY TAKES THE FORM OF A SHORT WAVE TROUGH AND EJECTS OUT
ACROSS THE ROCKIES. THIS WAVE HELPS TO BREAK DOWN THE RIDGE ACROSS
THE CENTRAL PLAINS.

THE UPPER LEVEL SHORT WAVE WILL CONTINUE TO PUSH INTO MONTANA AND
CANADA WHILE A SURFACE LOW DEVELOPS ACROSS THE NORTHERN ROCKIES.
THIS SYSTEM...COMBINED WITH FAIRLY DECENT ISENTROPIC LIFT...AND
MOISTURE WILL LIKELY MAKE FOR A VERY WET THURSDAY ACROSS THE PLAINS.
THE BEST LIFT AND MOISTURE AXIS WILL BEGIN TO SHIFT EASTWARD
THURSDAY EVENING DECREASING PRECIPITATION CHANCES ACROSS THE WEST.
HOWEVER...A SECONDARY LOW PRESSURE SYSTEM WILL DEVELOP ACROSS KANSAS
AND COLORADO...ALLOWING ANY MOISTURE ACROSS THE EAST TO WRAP ACROSS
PORTIONS OF CENTRAL AND NORTHERN NEBRASKA. SATURDAY LOOKS TO BE THE
DRIEST DAY OF THE LONG TERM...AS BOTH MODELS POSITION THE DRY SLOT
OVER MUCH OF THE REGION. HIGH TEMPERATURES ON BOTH FRIDAY AND
SATURDAY MAY BE A BIT TOO LOW ESPECIALLY ACROSS THE SOUTH. WITH GOOD
MIXING AND THE POTENTIAL FOR SOME SUNSHINE DURING THE AFTERNOON
HOURS..MID 70S TO EVEN UPPER 70S SEEM FEASIBLE FOR SOUTHERN
LOCATIONS. DECIDED AGAINST ANY DRASTIC CHANGES TO THE FORECAST AT
THIS POINT AS MODELS REMAIN IN DISAGREEMENT AND TIMING AND
POSITIONING OF THE DRY SLOT COULD CHANGE.

BY SATURDAY EVENING...THE GFS SOLUTION TAKES A PROACTIVE APPROACH TO
THE WEEKEND AND SUGGESTS AN UPPER LEVEL CLOSED LOW/SHORT WAVE WILL
SLIDE ACROSS THE REGION SATURDAY NIGHT. IN TURN..THE SFC LOW STRENGTHENS
AND IS EXPECTED TO SLIDE COMPLETELY OUT OF THE REGION BY SUNDAY. AS
A RESULT...SUNDAY APPEARS TO BE DRY. HOWEVER...THE ECMWF SOLUTION
INSTEAD SUGGESTS AN UPPER LEVEL SHORT WAVE RIDGE SLIDING ACROSS THE
REGION SATURDAY NIGHT. THE SFC LOW LINGERS ACROSS THE
REGION...SUGGESTING A FAIRLY WET SUNDAY.

THE END OF THE WEEK COULD BECOME QUITE INTERESTING AS INSTABILITY
PARAMETERS CONTINUE TO SUGGEST THE POSSIBILITY FOR SEVERE WEATHER.
FOR THURSDAY AFTERNOON...MODELS INDICATE AROUND 1000 J/KG ACROSS THE
KANSAS COUNTIES DURING THE AFTERNOON. THE LARGEST SEVERE WEATHER
POTENTIAL APPEARS TO BE BOTH FRIDAY AND SATURDAY AFTERNOON.
DEPENDING UPON THE DRY SLOT AND LOCATION OF THE FRONTAL BOUNDARY/DRY
LINE...MODELS INDICATE AROUND 1700 J/KG ACROSS THE FORECAST AREA.
