AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
330 PM CDT TUE OCT 16 2007

.SYNOPSIS...
    AT 19Z...SURFACE ANALYSIS SHOWED THE LOW HAD MOVED OFF TO
SOUTHEAST SOUTH DAKOTA WITH THE FRONT DRAGGING DOWN THROUGH EXTREME
SOUTHEAST NEBRASKA THROUGH CENTRAL KANSAS SOUTHWESTWARD INTO
NORTHERN NEW MEXICO AND BACK ALONG THE EASTERN SLOPE OF THE ROCKIES
TO A LOW IN CENTRAL MONTANA. ANOTHER STRONG CYCLONE WAS LOCATED NEAR
THE GULF OF ALASKA WITH A FRONT DRAPED ACROSS CENTRAL BRITISH
COLUMBIA TO SOUTHERN SASKATCHEWAN. IN THE UPPER LEVELS...THE 6.7U
WATER VAPOR IMAGERY SHOWED A PROMINENT VORTEX OVER SOUTHWEST
MINNESOTA AND ANOTHER OVER THE GULF OF ALASKA.
&&

.SHORT TERM...TONIGHT THROUGH THURSDAY.
    FOR WEDNESDAY NIGHT AND THURSDAY...A DEEP CYCLONE WILL DEVELOP
ON THE HIGH PLAINS WEDNESDAY AFTERNOON OR EVENING AND MOVE ACROSS
THE NORTHERN PLAINS THURSDAY. SCATTERED THUNDERSTORMS ARE EXPECTED
WEDNESDAY EVENING WITH SHOWERS CONTINUING THROUGH THURSDAY. OF
PARTICULAR CONCERN IS THE WIND THURSDAY. STRONG COLD ADVECTION AND
A TIGHT PRESSURE GRADIENT WILL GENERATE STRONG WIND. WIND IS LIKELY
TO APPROACH WARNING CRITERIA...AND A HIGH WIND WATCH MAY BE REQUIRED
WITH A SUBSEQUENT FORECAST ISSUANCE.
&&

.LONG TERM...FRIDAY THROUGH TUESDAY.
    THE LATEST RUN OF THE GLOBAL MODEL SHOWS A SOLUTION SIMILAR TO
THE 00Z EUROPEAN...THOUGH ABOUT 12 HOURS FASTER WITH THE WEEKEND
SYSTEM THAN THE EUROPEAN SHOWS. THIS WOULD INDICATE A FAIRLY
PROGRESSIVE PATTERN THROUGH EARLY NEXT WEEK.
    A SURFACE LOW COMES OUT OF THE NORTHERN HIGH PLAINS SATURDAY.
THIS IS ENOUGH FOR AT LEAST SOME CHANCE OF RAIN OVER WESTERN
NEBRASKA SATURDAY AND SATURDAY NIGHT AND OVER MOST OF WESTERN AND
NORTH CENTRAL NEBRASKA SUNDAY. CONSIDERING THE UNCERTAINTY IN THE
TIMING OF THIS FEATURE...CONFIDENCE IN THE FORECAST IS NOT HIGH.
    AFTER THE SYSTEM PASSES SUNDAY NIGHT...AN UPPER RIDGE BUILDS IN
THE WEST. THIS SHOULD BRING DRY WEATHER AND WARMER TEMPERATURES TO
WESTERN AND NORTH CENTRAL NEBRASKA EARLY NEXT WEEK.
&&

.AVIATION...
    IFR/MVFR CONDITIONS WILL PERSIST ACROSS NORTH CENTRAL INTO
EASTERN NEBRASKA THROUGH THE EVENING HOURS. THESE CONDITIONS ARE DUE
TO CIG HGHTS AS VSBYS REMAIN UNRESTRICTED. STRONG SOUTHERLY FLOW
WILL BRING A NEW FETCH OF MOISTURE INTO THE HIGH PLAINS OVERNIGHT.
STRATUS IS EXPECTED TO FORM OR ADVECT BACK INTO THE REGION DURING
THE EARLY MORNING HOURS WITH IFR CONDITIONS PREVAILING. IFR/LIFR
CONDITIONS WILL BE WIDESPREAD WITH MOST CIG HGHTS BELOW 1KFT AND
PATCHY FOG REDUCING VSBYS DOWN TO NEAR 3 MILES. SCATTERED CONVECTION
WILL ALSO BE POSSIBLE FROM NEAR SUNRISE THROUGH MUCH OF THE DAY ON
WEDNESDAY...ESPECIALLY ALONG AND EAST OF HIGHWAY 83. STORMS WILL
HAVE THE POTENTIAL TO BECOME STRONG AND MAY POSE THREAT TO SMALL
AIRCRAFT.
&&

.LBF WATCHES/WARNINGS/ADVISORIES...NONE.
