AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE NORTH PLATTE NE
658 PM CST TUE DEC 9 2003

...TONIGHTS LOWS WERE UPDATED ACROSS THE SNOW FIELD...

AT 602 PM VTN FELL TO 4F. THATS 4 BELOW THE COLDEST GUIDANCE FOR VTN
AT 12Z WEDS.  LOCAL STUDIES INDCATE THE LOW AT VTN WILL FALL 10F TO
14F BELOW GUIDANCE.  FORECAST HAS BEEN UPDATED FOR LOW TEMPS NEAR OR
JUST BELOW ZERO ACROSS THE FRESH SNOW FIELD.  SFC WINDS WILL BE
FAVORABLE FOR NEAR ZERO. PESKY LOW LEVEL MOISTURE COULD PUT THE
DAMPER ON STRONG RADIATIONAL COOLING HOWEVER BUT STUDIES INDICATE
JUST A FEW HOURS OF CLEAR SKIES WILL DO THE TRICK AND ONLY SE SFC
WINDS WILL BREAK THE INVERSION.

PREVIOUS DISCUSSION...

...FORECAST CONCERNS WILL BE TEMPERATURES AND CLOUD COVER SHORT TERM
THEN ACTIVE PATTERN AND STORM SYSTEMS IN EXTENDED...

.NEAR TERM...TODAY THROUGH THURSDAY...SNOW HAS ENDED AND CLOUDS HAVE
BEGUN TO DECREASE IN THE WEST. THIS TREND WILL CONTINUE OVERNIGHT
BECOMING PARTLY CLOUDY TO MOSTLY CLEAR. LOW TEMPERATURES COULD BE
CHILLY WITH FRESH SNOW AND DECREASING CLOUDS. WILL PROBABLY BE GOING
NEAR OR BELOW GUIDANCE NUMBERS AS WEAK HIGH PRESSURE BUILDS IN BEHIND
EXITING STORM SYSTEM. WEDNESDAY LOOKING DRY WITH TEMPERATURES IN THE
20S IN THE CENTRAL AND NORTHEAST ZONES AND STRUGGLING TO REACH THE
LOWER 30S IN THE SOUTHWEST DUE TO SNOW PACK. A FAST MOVING WEAK
DISTURBANCE TO MOVE ACROSS THE DAKOTAS AND NORTHERN NEBRASKA ON
THURSDAY WILL BRING A SLIGHT CHANCE OF SNOW TO NORTHERN ZONES AND
KEEP TEMPERATURES GENERALLY IN THE 20S.

.EXTENDED...FRIDAY THROUGH TUESDAY...MODELS CONTINUE ACTIVE PATTERN
OVER THE LOWER 48. WEAK SHORT WAVE TO MOVE THROUGH THE AREA FRIDAY
AND SATURDAY. CURRENT THOUGHT IS THAT MOST OF CENTRAL AND SOUTHERN
PLAINS COULD SEE AT LEAST LIGHT PRECIPITATION. WEAK RIDGING BEHIND
SYSTEM WILL BE SHORT LIVED AS ANOTHER SYSTEM DEVELOPS AND MOVES
ACROSS PLAINS ON MONDAY INTO TUESDAY. THIS SECOND SYSTEM APPEARS ATTM
TO POSSIBLY BE SETTING UP TO DELIVER SOME SIGNIFICANT SNOWFALL. STILL
WAY TO EARLY TO PINPOINT DETAILS OF THIS STORM SYSTEM...BUT WILL KEEP
AN EYE ON THIS OVER THE NEXT SEVERAL DAYS.

&&

.SYNOPSIS...MID LEVEL LOW SPINNING ACROSS CENTRAL KS...PER LATEST
WATER VAPOR LOOPS. ANOTHER SYSTEM PLOWING INTO THE PACIFIC COAST. AT
THE SURFACE LOW PRESSURE ROTATING ALONG THE SOUTHEAST KANSAS AND
MISSOURI BORDER...TRACKING NORTHEAST. MEANWHILE HIGH PRESSURE
BUILDING ACROSS THE WESTERN PLAINS.
