AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
325 PM CDT SAT APR 19 2008

.SYNOPSIS...
    AT 18Z...HAND ANALYSIS OF THE MSL DATA SHOWED A LOW PRESSURE
SYSTEM OVER NORTHWEST WYOMING WITH SEVERAL FRONTS/BOUNDARIES. ONE
FRONT WAS A WARM FRONT EXTENDING UP INTO SASKATCHEWAN AND MANITOBA
AND A BOUNDARY ACROSS WESTERN NEBRASKA. IN THE UPPER LEVELS...THE
6.7 MICRON WATER VAPOR IMAGERY SHOWED A DEVELOPING WAVE OVER
WESTERN MONTANA. OTHERWISE...BROAD ANTICYCLONIC FLOW ACROSS THE
PLAINS.
&&

.SHORT TERM...TONIGHT THROUGH TUESDAY.
    VERY WARM AND DRY CONDITIONS WILL CONTINUE SUNDAY. THE PRESSURE
GRADIENT AHEAD OF THE NEXT FRONT WILL WORK UP SOME WINDY CONDITIONS
AS WELL IN CENTRAL AND NORTH CENTRAL NEBRASKA.
    A FRONT COMING THROUGH SUNDAY NIGHT AND MONDAY WILL BRING COOLER
TEMPERATURES TO WESTERN NEBRASKA. THE UPPER SYSTEM FOLLOWING IN THE
WAKE OF THE FRONT IS LIKELY TO PRODUCE ELEVATED 2D-FRONTOGENESIS.
THIS SHOULD CREATE ENOUGH LIFT FOR SCATTERED SHOWERS ACROSS THE
NORTH AND WEST TUESDAY NIGHT. IN THE NORTHWEST...IT APPEARS THAT IT
SHOULD BE COLD ENOUGH FOR LIGHT SNOW SHOWERS...WHILE IN THE EAST...
THERE IS ENOUGH INSTABILITY TO WARRANT A MENTION OF THUNDERSTORMS.

.LONG TERM...TUESDAY NIGHT THROUGH SATURDAY.
    ANOTHER FRONT AND STORM SYSTEM IS EXPECTED TO CROSS THE CENTRAL
PLAINS WEDNESDAY NIGHT AND THURSDAY. THIS BRINGS A CHANCE OF
PRECIPITATION ONCE AGAIN TO MOST OF NEBRASKA. CONDITIONS IN SOUTHERN
AND EASTERN NEBRASKA ARE FORECAST TO BE PRETTY UNSTABLE...SO
THUNDERSTORMS ARE POSSIBLE. OTHERWISE... THE COLD AIR IS FORECAST TO
STAY WELL NORTH OF THE AREA AND SEASONABLE TEMPERATURES ARE LIKELY
INTO NEXT WEEKEND.
&&

.AVIATION...
    SOUTHERLY WINDS WILL PULL MOISTURE INTO WESTERN NEBRASKA
OVERNIGHT. LLVL RH FIELD INDICATE SOME STRATUS DEVELOPMENT ACROSS
WESTERN KANSAS INTO THE EASTERN PANHANDLE BY SUNRISE. GUIDANCE TREND
IS BACKING OFF THIS POTENTIAL SO HAVE MENTIONED ONLY SCATTERED DECK
IN LBF TAF. CIGS HGHTS IN THE WEST COULD REACH IFR CONDITIONS BUT
MVFR SEEMS MORE LIKELY IN THE 150OFT AGL RANGE. A 50+KT LLVL JET
WILL DEVELOP OVER CWA TONIGHT AND DEPENDING ON AMOUNT OF DE-COUPLING
LOW LEVEL WIND SHEAR MAY DEVELOP.
&&

.FIRE WEATHER...
    CRITICAL FIRE WEATHER CONDITIONS DEVELOPED ACROSS WESTERN CWA
TODAY...WITH CONDITIONS DRIER THAN MOST GUIDANCE INDICATED...MAINLY
BECAUSE WINDS HAVE MORE OF WESTERLY COMPONENT THAN MODELS DEPICTED.
CRITICAL CONDITIONS COULD VERY LIKELY BE MET ON SUNDAY...ESPECIALLY
CONCERNING RH LEVELS. SFC TROF WILL PULL OUT OF HIGH PLAINS INTO
WESTERN CWA AND PULL THE DRY AIR OF THE HIGHER TERRAIN IN THE
AFTERNOON. RH VALUES LOOK TO FALL INTO THE LOWER TEENS AND POSSIBLY
SINGLE DIGITS EASTERN CO/WY INTO WESTERN SANDHILLS AND SOUTHWEST
NEBRASKA. LOWER CONFIDENCE IN WIND CRITERIA IS LIMITING FACTOR IN
ISSUANCE OF FIRE WX WATCH AND SHORT LEAD TIME HEADLINES ARE MOST
PROBABLE AGAIN FOR SUNDAY. DRY AIR MOVING INTO CWA BEHIND COLD FRONT
ON MONDAY LOOKS TO DROP RH LEVELS DOWN TO NEAR 15 PERCENT AGAIN OVER
LARGE PART OF WESTERN CWA...BUT WITH HIGH PRESSURE BUILDING INTO
REGION WINDS SHOULD REMAIN UNDER 25 MPH.
&&

.LBF WATCHES/WARNINGS/ADVISORIES...RED FLAG WARNING UNTIL 7 PM MDT
FIRE ZONES 204 AND 210.
