.SHORT TERM...(THIS EVENING THROUGH THURSDAY)
ISSUED AT 353 PM CDT WED APR 9 2014

COLD FRONT WILL PUSH ACROSS THE AREA TONIGHT. MOISTURE IS THE BIG
QUESTION...AS VERY DRY AIR IS PRECEDING THE FRONT. MORNING SOUNDING
ONLY HAD 0.25 INCHES OF PWATS...OR 68 PERCENT OF NORMAL...AND THAT
WAS BEFORE WE SOARED TO 80 THIS AFTERNOON. DO HAVE SOME HIGH CLOUDS
SO THERE IS SOME ELEVATED MOISTURE TO WORK WITH. VERY STEEP LAPSE
RATES NEAR AND BEHIND THE FRONT AS COLD AIR ARRIVES. WILL INCLUDE A
SLIGHT CHC FOR SHOWERS AND SPRINKLES FURTHER SOUTH DUE TO MORE DRY
AIR. NEGATIVE LI/S EARLY IN THE NIGHT AND CAN NOT RULE OUT A FEW
RUMBLES OF THUNDER NEAR THE S DAKOTA BORDER EARLY. FRONT QUICKLY
MOVES SOUTH WITH PRECIP CHANCE DIMINISHING OVERNIGHT.

TOMORROW WITH PACIFIC HIGH PRESSURE SETTLING IN BEHIND THE FRONT
HIGHS SHOULD REBOUND INTO THE 60S. LATE IN THE DAY A WARM FRONT WILL
LIFT IN FROM THE WEST. LATE AFTERNOON THUNDERSTORMS POSSIBLE ACROSS
THE FRONT RANGE/PANHANDLE. DID INCLUDE SOME LOW POPS FOR THE EASTERN
PANHANDLE...WHICH MAYBE TO EARLY.

USED A BLEND FOR THE FORECAST. SHOWERS MOVING THROUGH FAST
NORTHWEST FLOW WITH WEAK COOL FRONT THURSDAY NIGHT. COULD BE AN
ISOLATED LIGHTNING STRIKE WITH WEAK INSTABILITY EARLY ON MAINLY IN
THE PANHANDLE. DROPPED POPS DOWN INTO SCHC WITH LIMITED MOISTURE.
TEMPERATURES CUT BACK INTO THE 70S BEHIND THE FRONT ON FRIDAY.
850MB TEMPERATURES AROUND 16 TO 17C ON SATURDAY BEFORE NEXT COLD
FRONT MOVES SOUTHEAST ACROSS THE FORECAST AREA ON SATURDAY.
TEMPERATURES WARMING INTO THE 70S AHEAD OF THE FRONT AND MAY HAVE
TO BE WARMED UP SOME. GENERALLY RAINSHOWERS EXPECTED BEHIND THE
FRONT BUT AS THE SYSTEM APPROACHES MAY ADD THUNDER WITH THE FROPA.
TEMPERATURES OVER NIGHT QUESTIONABLE AND HAVE A MIX OF SNOW
CONTINUING OVER NORTHWEST ZONES. TEMPERATURES COOLING INTO THE 40S
ON SUNDAY WITH TEMPERATURES COOLING THROUGH THE DAY WITH CHANCES
OF SNOW. MEX GIVING US SOME SNOW. SYSTEM SHOULD BE FAR ENOUGH
SOUTH SUNDAY NIGHT TO DROP PRECIPITATION SUNDAY NIGHT.

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z THURSDAY EVENING)
ISSUED AT 612 PM CDT WED APR 9 2014

SHOWERS CAN BE EXPECTED IN NORTHERN NEBRASKA AS A COLD FRONT PUSHES
THROUGH...BUT COVERAGE WILL BE LESS THAN 30 PERCENT. THEREFORE THE
PROBABILITY OF RAIN AT ANY ONE SITE IS LOW. MIDDLE CLOUDS AT OR
ABOVE 8000 FEET AGL AND VISIBILITY 5SM OR GREATER ARE EXPECTED AS
THE FRONT GOES THROUGH.

WIND IS THE ONLY OTHER CONCERN TONIGHT. WEST TO SOUTHWEST WIND WILL
CONTINUE AT 10-15KT UNTIL THE FRONT GOES THROUGH TOWARD 05-07Z. AT
THAT TIME THE WIND WILL BECOME 330-360 AT 13-16G24-27KT.

BRIEF INCREASE BEHIND THE FRONT CAN BE EXPECTED...WITH A SLOW
DIMINISH THROUGH THE NIGHT. SHOWERS/SPRINKLES ALONG AND BEHIND THE
FRONT...WITH A FEW LIGHTNING STRIKES POSSIBLE EARLY ON.

COOLER FOR THURSDAY WITH MIN RH VALUES REMAINING ABOVE 20 PERCENT
AND MOST AREAS CLOSER TO 30 PERCENT. WARM FRONT LATE IN THE DAY WILL
LIFT EAST ACROSS THE AREA BRINGING A CHANCE FOR THUNDERSTORMS. THIS
WILL ALSO BRING A WARM UP FOR FRIDAY. HIGHS NOT AS WARM AS
TODAY...ALTHOUGH SHOULD STILL SEE HIGHS INTO THE 70S. WILL NEED TO
MONITOR THE TEMPS AND DEW PTS AS MIN RH VALUES AROUND 20
PERCENT...AND WOULD NOT TAKE MUCH TO SEE MIN RH VALUES AROUND THE
CRITICAL 15 PERCENT.
