Drought in Nebraska, September 1 to 30, 2012

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
1146 PM MDT FRI AUG 31 2012

.UPDATE...
ISSUED AT 903 PM MDT FRI AUG 31 2012

00Z SOUNDINGS INDICATE WELL MIXED AND VERY DRY AIR MASS SURROUNDING
THE AREA THIS EVENING AND WITH EXPECTED WIND FIELD NOT EXPECTING A
RADICAL CHANGE IN AIR MASS THROUGH TOMORROW. GIVEN THE SIMILAR
CONDITIONS HAVE UPGRADED A PORTION OF FIRE WEATHER WATCH TO RED
FLAG WARNING BUT HAVE LEFT SOUTHERN TWO COUNTIES AS WATCH AS
CONFIDENCE IN WIND SPEEDS TOO LOW TO UPGRADE ATTM.

OTHERWISE...NOTICED A SHARP INCREASE IN TDS COMING IN FROM THE
EAST AND GIVEN THE LIGHT VARIABLE WINDS AND CLEAR SKIES HAVE A FEW
CONCERNS ABOUT FOG FORMATION ACROSS NORTON AND GRAHAM COUNTIES.
FAIRLY LOW PROBABILITY AT THIS POINT...BUT THINK A PATCHY FOG
MENTION IS WARRANTED.

.SHORT TERM...(THIS EVENING THROUGH SATURDAY NIGHT)
ISSUED AT 216 PM MDT FRI AUG 31 2012

TONIGHT-SATURDAY...THE GUSTY SOUTH TO SOUTHEAST WINDS WILL QUICKLY
DECREASE BY 01Z OR SO TONIGHT AND VEER TO THE SOUTHWEST THROUGH THE
REMAINDER OF THE NIGHT BEFORE BACKING TO THE SOUTH DURING THE DAY
SATURDAY AND INCREASING SLOWLY IN SPEED. LOW TEMPERATURES TONIGHT IN
THE MID 50S TO LOW 60S WITH HIGH TEMPERATURES SATURDAY A FEW DEGREES
WARMER WITH 95-100 ACROSS THE AREA.

.LONG TERM...(SUNDAY THROUGH FRIDAY)
ISSUED AT 216 PM MDT FRI AUG 31 2012

THE UPPER LEVEL RIDGE WILL DOMINATE THE WEATHER PATTERN THROUGH
SUNDAY.  POINT SOUNDINGS CONTINUE TO SHOW DEW POINT DEPRESSIONS IN
EXCESS OF 5 DEGREES SO DO NOT FORESEE ANY CHANCE FOR PRECIPITATION.

SUNDAY A PRE-FRONTAL TROUGH WILL DEVELOP OVER THE WESTERN HALF OF
THE AREA...REMAINING THERE THROUGH THE DAY.  LATE SUNDAY AFTERNOON
AN UPPER LEVEL SHORT WAVE TROUGH AND ASSOCIATED COLD FRONT WILL MOVE
INTO THE AREA FROM THE NORTHWEST.  AS THE DAY PROGRESSES LIFT
INCREASES ALONG THE FRONT THAT WILL LAY ACROSS THE WESTERN PART OF
THE TRI-STATE AREA.  MODELS DISAGREE WITH THE AMOUNT OF MID LEVEL
MOISTURE THAT WILL BE AVAILABLE TO WORK WITH.  IN ADDITION LAPSE
RATES ABOVE 650 MB...THE BOTTOM OF THE MOIST LAYER...WILL KEEP THE
ENVIRONMENT STABLE ENOUGH TO INHIBIT CONVECTION.  WITH SURFACE
CONVERGENCE ALONG THE FRONT UP THROUGH 700 MB AS WELL AS SURFACE TO
700 FRONTOGENESIS AND A SHORT WAVE TROUGH MOVING OVER THE FRONT
DURING THE EARLY EVENING...WILL TREND POPS UPWARD BUT KEEP THEM IN
THE SILENT CATEGORY NORTH AND WEST OF A KIT CARSON TO MCCOOK LINE.
DURING THE OVERNIGHT HOURS LIFT ALONG THE FRONT DECLINES AS THE
SHORT WAVE FILLS AND THE FRONT MOVES FURTHER AWAY FROM THE TROUGH.

ON A SIDE NOTE RECORD TO NEAR RECORD HIGH TEMPERATURES CAN BE
EXPECTED SUNDAY AFTERNOON.  REFER TO CLIMATE SECTION FOR
SPECIFIC VALUES.

THE MONDAY THROUGH FRIDAY PERIOD LOOKS TO HAVE PLENTY OF CHANCES FOR
RAINFALL AS NUMEROUS UPPER LEVEL DISTURBANCES MOVE THROUGH THE
FLOW.  THE BEST CHANCES FOR RAINFALL WILL BE TUESDAY NIGHT INTO
WEDNESDAY AND AGAIN ON FRIDAY WHEN A COLD FRONT WILL MOVE THROUGH
THE AREA.  HAVE MORE CONFIDENCE WITH THE BETTER PRECIP. CHANCES WITH
THE TUESDAY NIGHT WEDNESDAY COLD FRONT THAN THE ONE ON FRIDAY SINCE
MODELS HAVE EITHER A SHORT WAVE TROUGH OR A RIDGE OVER THE TRI-STATE
AREA.  TEMPERATURES WILL BE WARMEST ON MONDAY THEN GRADUALLY COOL
THROUGH THE REST OF THE WEEK...WITH SLIGHTLY ABOVE NORMAL
TEMPERATURES BY THE END OF THE WORK WEEK.

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z SATURDAY NIGHT)
ISSUED AT 1141 PM MDT FRI AUG 31 2012

VFR CONDITIONS EXPECTED TO PREVAIL AT BOTH LOCATIONS THROUGHOUT
THE PERIOD WITH SOUTHERLY WINDS INCREASING TO AROUND 13 KTS
TOMORROW AFTERNOON. EXPECT TO SEE AT LEAST PATCHY FOG DEVELOP IN
SOUTH CENTRAL NEBRASKA SPREADING TOWARDS MCK AROUND 12Z...BUT
PROBABILITIES TOO LOW TO REDUCE FLIGHT CATEGORIES AT THIS TIME.

&&

.FIRE WEATHER...
ISSUED AT 216 PM MDT FRI AUG 31 2012

MODELS HAVE UNDERDONE WINDS THIS AFTERNOON ALONG THE CO/KS BORDER
AND AM EXPECTING THAT THEY MAY HAVE DONE THE SAME FOR SATURDAY
AFTERNOON ALTHOUGH MET/MAV GUIDANCE WINDS ARE A BIT STRONGER.
LEANING TOWARDS THE WINDS BEING SLIGHTLY HIGHER THEN MODELS DEPICT
WHICH RESULTS IN 15-20 MPH S/SE WINDS..FURTHER EAST 5-10 MPH. RH
VALUES WILL AGAIN DROP AS LOW AS 10 PERCENT RESULTING IN CRITICAL
FIRE WEATHER CONDITIONS POSSIBLY BEING MET. AS A RESULT AND PER
COORDINATION WITH SURROUNDING OFFICES HAVE ISSUED A FIRE WEATHER
WATCH FOR LOCATIONS GENERALLY ALONG THE CO/KS BORDER AND ADJACENT
COUNTIES IN FAR SOUTHWEST NEBRASKA AND NORTHWEST KANSAS.

SUNDAY AFTERNOON RELATIVE HUMIDITIES WILL RANGE FROM 15 TO 20
PERCENT.  WINDS WILL BE UP TO 20 MPH SO AM NOT TOO CONCERNED
CONDITIONS WILL MEET FIRE CRITERIA AT THIS TIME.  HOWEVER...THE DRY
FUELS IN PLACE COMBINED WITH A LIGHT BREEZE WILL MAKE FOR HAZARDOUS
FIRE WEATHER CONDITIONS.
