AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE OMAHA/VALLEY NE
626 AM CDT SUN MAR 9 2014

.SHORT TERM...(TODAY THROUGH TUESDAY)
ISSUED AT 345 AM CDT SUN MAR 9 2014

TEMPERATURES FOR THE NEXT FEW DAYS AND THE CHANCE FOR PCPN FROM LATE
MONDAY NIGHT INTO TUESDAY NIGHT WILL PROVIDE THE MAIN FORECAST
CHALLENGES.

SOME HIGH LEVEL CLOUDINESS SHOULD MOVE OVER THE AREA TODAY BUT IS
NOT EXPECTED TO AFFECT TEMPERATURES MUCH. MILD TEMPERATURES ALOFT
(850 MB TEMPERATURES MAINLY 9 TO 12 DEGREES C) WILL BE MIXED
DOWNWARD THIS AFTERNOON WITH MODEST WEST/SOUTHWEST WINDS. MOST HIGHS
SHOULD REACH THE 60S...WITH SOME READINGS AROUND OR ABOVE 70 WEST
AND SOUTHWEST OF LINCOLN. NO PCPN IS EXPECTED THROUGH MONDAY. LOWS
TONIGHT WILL DROP INTO THE 30S. HIGHS MONDAY SHOULD BE ABOUT THE
SAME IN OUR SOUTHERN ZONES...BUT SOME COOLER AIR WILL BE SLIDING
INTO THE NORTH AND MIXING WILL PROBABLY NOT BE QUITE AS DEEP. IN
ADDITION...IT APPEARS THAT CLOUD COVER WILL BE THICKENING ABOVE
15000 FEET. SO...HAVE HIGHS MONDAY AGAIN MAINLY IN THE 60S. THESE
WILL RANGE FROM LOWER 60S FOR THE NORTHEAST 1/3 OF THE FORECAST
AREA TO AROUND 70 TO THE WEST AND SOUTH OF LINCOLN.

THINGS GET MORE INTERESTING MONDAY NIGHT THROUGH TUESDAY. LOW
PRESSURE AT THE SURFACE SHOULD ORGANIZE OVER NORTHWEST KANSAS OR
SOUTHWEST NEBRASKA MONDAY NIGHT...AS SHORTWAVE ENERGY APPROACHES
FROM THE ROCKIES. MODELS SHOW MODEST FORCING CENTERED ALONG A LINE
FROM NORTHWEST NEBRASKA INTO SOUTHEAST SOUTH DAKOTA BY 12Z TUESDAY.
THIS THEN PROGRESSES SOUTHEASTWARD ACROSS THE FORECAST AREA INTO
TUESDAY EVENING. AS THE COLD AIR DEEPENS AND MOVES SOUTHEAST...
TEMPERATURES ALOFT COOL AND WE SHOULD SEE SOME SNOW WITH THIS
SYSTEM. ANY SNOW ACCUMULATION TUESDAY MORNING WILL LIKELY STAY
ACROSS NORTHEAST NEBRASKA...BUT LIGHT ACCUMULATIONS SHOULD PUSH
TOWARD OMAHA AND LINCOLN DURING THE AFTERNOON. DYNAMICS WEAKEN
TUESDAY EVENING SO PCPN AMOUNTS SHOULD ALSO BE DECREASING.

.LONG TERM...(TUESDAY NIGHT THROUGH SATURDAY)
ISSUED AT 345 AM CDT SUN MAR 9 2014

LIGHT SNOW SHOULD END BY LATE TUESDAY NIGHT...WITH LOWS DROPPING
INTO THE 25 TO 30 DEGREE RANGE BY WEDNESDAY MORNING. MUCH OF THE
REST OF THE WEEK SHOULD BE DRY. HIGHS WILL REACH THE 40S TO AROUND
50 WEDNESDAY...THEN REACH MAINLY 50S THURSDAY THROUGH SATURDAY AS
WEAK RIDGING ALOFT TRIES TO BUILD EAST FROM THE ROCKIES. A SHORTWAVE
TROUGH DROPPING TOWARD OUR AREA IN THE NORTHWEST FLOW IS EXPECTED TO
AMPLIFY AND BRING A CHANCE OF LIGHT RAIN AND LIGHT SNOW BY SATURDAY
NIGHT AND SUNDAY.
