AREA FORECAST DISCUSSION

322 PM CDT WED OCT 3 2012

.SHORT TERM...TONIGHT THROUGH SATURDAY.

COLDER TEMPERATURES INTO THE WEEKEND BEHIND COLD FRONT MOVING
THROUGH TONIGHT IS THE PRIMARY FORECAST CONCERN. SMALL RAIN CHANCES
TONIGHT AND FRIDAY WILL ALSO NEED ATTENTION.

GUSTY SOUTH WINDS...SUNSHINE AND DRY LOW LEVEL AIR HAVE PUSHED
TEMPERATURES INTO THE LOWER 80S AT MOST SPOTS THIS AFTERNOON.
RELATIVE HUMIDITIES HAVE DROPPED TO OR BELOW 20 PERCENT SO WILL
CONTINUE RED FLAG WARNING FOR THE REMAINDER OF THE AFTERNOON.

STRONG COLD FRONT WAS NOTED FROM CENTRAL SOUTH DAKOTA INTO WESTERN
NEBRASKA...AND WAS MAKING STEADY SOUTHEAST PROGRESS TOWARD EASTERN
NEBRASKA. EXTRAPOLATION OF MOVEMENT ALONG WITH SHORT TERM MODEL
OUTPUT POINTS TO FRONT ARRIVING IN NORTHEAST NEBRASKA THIS
EVENING...THEN OMAHA AND LINCOLN AREAS NEAR OR JUST PAST MIDNIGHT.
FRONT SHOULD BE EXITING SOUTHEAST NEBRASKA AND SOUTHWEST IOWA BY
SUNRISE THURSDAY. STRONG PRESSURE RISES BEHIND THE FRONT SUGGEST
STRONG NORTHWEST WINDS WILL FOLLOW WIND SHIFT...WITH GREATEST
IMPACT SWINGING THROUGH EASTERN SOUTH DAKOTA. COULD SEE SUSTAINED
WINDS OVER 30 AND GUSTS TO 40 FOR A SEVERAL HOUR WINDOW AROUND
MIDNIGHT IN FAR NORTHEAST NEBRASKA. WILL ISSUE A WIND ADVISORY FOR
THAT SMALL AREA OF NEBRASKA.

STRONG MID LEVEL JET ROUNDING BASE OF UPPER WAVE ROTATING THROUGH
THE DAKOTAS WILL ENHANCE LIFT ACROSS EASTERN NEBRASKA AND WESTERN
IOWA LATE TONIGHT AND THURSDAY MORNING. MOISTURE PROFILES ARE
RELATIVELY MEEK...WITH MOST SATURATION POTENTIAL ONLY AT MID LEVELS.
SO CHANCES FOR WIDESPREAD PRECIPITATION LOOK LOW...BUT CAN NOT RULE
OUT A FEW SHOWERS GIVEN DYNAMICS. AND THERE IS SOME MID LEVEL
INSTABILITY AS PER GFS/NAM 850MB CAPE/LIFTED INDEX PARAMETERS. WILL
MAINTAIN LOW POPS TONIGHT AND THURSDAY MORNING WITH ISOLATED
THUNDER MENTION IN OUR SOUTH.

CLOUDS AND PRECIP LOOK TO PUSH SOUTHEAST THROUGH THE DAY
THURSDAY...ALLOWING SOME SUNSHINE AND DECENT MIXING TO PUSH
TEMPERATURES BACK INTO THE 50S AFTER MORNING LOWS IN THE 40S.
SOUTHEAST NEBRASKA AND SOUTHWEST IOWA MAY HIT 60.

COLD SURFACE HIGH PRESSURE WILL BEGIN BUILDING INTO THE REGION
THURSDAY NIGHT AND CONTINUE INTO SATURDAY. MEANWHILE ANOTHER UPPER
WAVE WILL DROP THROUGH THE HIGH PLAINS...WHICH MAY BRING CLOUDS AND
MAYBE LIGHT RAIN TO OUR AREA ON FRIDAY. FRIDAY MORNING LOWS WILL BE
TRICKY WITH A BATTLE OF COLD AIR AND DECREASING WINDS POTENTIALLY
BEING OVERRUN BY MID/HIGH CLOUDS. THINK A QUICK COOLING THURSDAY
EVENING WILL PUSH LOWS INTO THE 20S AND 30S BEFORE THICKER CLOUDS
MOVE IN LATE THURSDAY NIGHT. THEN CLOUDS AND LIGHT NORTH WINDS
SHOULD HOLD TEMPERATURES CLOSE TO 50 ON FRIDAY. CLEARING SKIES
FRIDAY NIGHT ALONG WITH LIGHT WINDS AND COLD HIGH PRESSURE POINT TO
THE COLDEST NIGHT OF THE FALL SO FAR. HAVE LOWS IN THE 20S FOR THE
NORTHERN TWO-THIRDS OF OUR AREA. THAT COLD START SHOULD HINDER
WARMING ON SATURDAY TO NEAR 50 ONCE AGAIN DESPITE MORE SUNSHINE.

DERGAN

.LONG TERM...SATURDAY NIGHT THROUGH WEDNESDAY

QUIET WEATHER IS EXPECTED FROM LATE WEEKEND INTO EARLY NEXT WEEK.
AFTER A COLD WEEKEND...TEMPERATURES WILL MODERATE BACK TO SEASONAL
NORMALS...WITH HIGHS INTO THE 60S AND LOWS IN THE 40S.  A DEEPENING
UPPER-LEVEL GREAT LAKES TROUGH IS PROGGED TO BRING A COLD FRONT
THROUGH THE AREA LATER TUESDAY/TUESDAY NIGHT.  THE MOISTURE PROFILE
LOOKS TOO DRY FOR PRECIPITATION IN THE AREA...BUT TEMPERATURES
SHOULD DROP BACK DOWN BELOW NORMAL MID-WEEK BEHIND THAT FRONT.
