AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
1221 PM CDT SUN MAY 15 2011

.UPDATE...MAINLY MINOR TWEAKS TO AFTERNOON FORECAST. EXTENSIVE
STRATOCUMULUS FIELD CONTINUES TO BLANKET THE CWA EARLY THIS
AFTERNOON TO THE NORTHWEST OF H5 VORT MAX DROPPING SOUTHEAST AND
CENTERED NEAR KANSAS CITY. NAM/RUC H85 RELATIVE HUMIDITY FIELDS
HAVE A DECENT HANDLE ON THE STEADY EROSION OF THE STRATUS ACROSS
NORTHERN NEBRASKA...AND EXPECT AT LEAST PARTIAL SUNSHINE TO SPREAD
SOUTHWARD ACROSS MUCH OF THE CWA AS THE AFTERNOON/EARLY EVENING
PROGRESSES...ESPECIALLY NORTH OF I-80. INSERTED A MENTION OF
ISOLATED SPRINKLES THROUGH 21Z ACROSS SOUTHERN 2/3 OF THE CWA TO
ACCOUNT FOR WEAK RADAR RETURNS EVIDENT MAINLY SOUTH OF I-80. MADE
VERY LITTLE CHANGE TO MAX TEMPS...AS EXPECT A DECENT LITTLE JUMP
LATE IN THE DAY AS MORE BREAKS IN THE OVERCAST OCCUR. STILL ONLY
MID 50S AT BEST MOST AREAS THOUGH. WINDS WILL GRADUALLY SLACKEN A
BIT AS THE AFTERNOON WEARS ON AND TURN A BIT NORTHEASTERLY.

&&

.AVIATION...18Z KGRI TAF. MAIN ISSUE IS CURRENT MVFR CIG...WHICH
IS EXPECTED TO RISE INTO VFR LEVELS/SCATTER OUT AS THE
AFTERNOON/EARLY EVENING WEARS ON. PARTIAL CLEARING IS ALREADY
WORKING SOUTHWARD ACROSS NORTHERN NEBRASKA...AND WILL AIM FOR A
21Z RETURN TO VFR CIG HEIGHT...ALTHOUGH A BROKEN STRATOCUMULUS
DECK COULD EASILY REMAIN IN PLACE UNTIL EARLY EVENING. WINDS THIS
AFTERNOON WILL BECOME NORTHEASTERLY...WITH CONTINUED GUSTS OF
15-20KT FOR SEVERAL MORE HOURS. OVERNIGHT...CLEAR SKIES WILL DOMINATE
THE REGION...AND WINDS WILL GO LIGHT AND VARIABLE AS A SURFACE
RIDGE AXIS PARKS ITSELF NEARBY. NOT ANTICIPATING ANY VSBY
RESTRICTIONS THROUGH THE PERIOD. SKIES WILL REMAIN CLEAR MONDAY
MORNING...AS LIGHT BREEZES BECOME EASTERLY ON THE BACK SIDE OF THE
RIDGE.

&&

.PREV DISCUSSION... /ISSUED 516 AM CDT SUN MAY 15 2011/

DISCUSSION...AMPLE LOW TO MID LEVEL STRATUS STREAMED ACROSS THE
FORECAST AREA OVERNIGHT...ASSOCIATED WITH WEAK FRONTOGENESIS
INDUCED BY AN UPPER LEVEL DISTURBANCE JUST TO THE NORTHEAST OF THE
LOCAL AREA. EXPECT THIS CLOUD COVER...AND ANY ASSOCIATED LIGHT
RAIN SHOWERS OR DRIZZLE...TO CONTINUE TO WEAKEN THROUGH THE
MORNING HOURS AS THE ASSOCIATED VORTICITY MAXIMUM TRACKS RAPIDLY
SOUTHEAST AND LOCAL FORCING BECOMES LESS FAVORABLE FOR ADDITIONAL
CLOUD OR SHOWER FORMATION. HOWEVER...WITH COOL AIR IN PLACE
ALOFT...DO NOT EXPECT A SIGNIFICANT REBOUND IN TEMPERATURES
TODAY...WITH HIGHS EXPECTED TO ONLY NUDGE A FEW DEGREES ABOVE
SATURDAYS CHILLY READINGS...THANKS MOSTLY TO A FEW BREAKS IN THE
STRATUS THIS AFTERNOON WHICH SHOULD ALLOW FOR A LITTLE SUNSHINE
LATE IN THE DAY.

MAIN CONCERN IN THE SHORT TERM WILL BE THE COMBINATION OF LIGHT
WINDS...CLEARING SKIES...AND COOL AIR IN PLACE ACROSS THE REGION
OVERNIGHT...WHICH WILL LIKELY LEAD TO AREAS OF PATCHY FROST AS
TEMPERATURES ARE EXPECTED TO DROP INTO THE LOWER TO MIDDLE 30S
ACROSS MOST OF THE AREA TONIGHT. WHILE PATCHY FROST WAS ALREADY
MENTIONED IN PREVIOUS FORECAST...WENT AHEAD AND TWEAKED EXPECTED
LOWS DOWN A COUPLE OF DEGREES AS WELL AS HIGHLIGHTED FROST IN THE
HWO...WHILE LEAVING POSSIBLE FROST ADVISORY HEADLINES TO DAY SHIFT
TODAY...AS THEY WILL HAVE A BETTER HANDLE ON WHETHER OR NOT STRATUS
WILL COMPLETELY BREAK ALLOWING FOR TEMPERATURES TO TRULY PLUMMET
OVERNIGHT TONIGHT.

WHILE GENERALLY DRY WEATHER IS EXPECTED ACROSS THE CENTRAL PLAINS
TO BEGIN THE NEW WORK WEEK...AS A RIDGE OF HIGH PRESSURE
ESTABLISHES ITSELF OVER THE AREA...CONTINUED UNSEASONABLY COOL
TEMPERATURES ARE EXPECTED TO PERSIST FOR SEVERAL DAYS.
HOWEVER...EXTENDED MODELS ARE NOW IN BETTER AGREEMENT HANDLING THE
LONG WAVE TROUGH WHICH IS EXPECTED TO DIG ACROSS THE SOUTHWEST
TUESDAY AND WEDNESDAY. THIS SHOULD RESULT IN A RETURN TO SOME
UNSETTLED WEATHER LOCALLY BY MIDWEEK...WITH A CHANCE OF
THUNDERSTORMS JUSTIFIED IN CURRENT FORECAST FOR THE LATER HALF OF
THE UPCOMING WORK WEEK AND INTO NEXT WEEKEND. BEST FORCING AND
INSTABILITY AT THIS TIME APPEARS TO THE THURSDAY AND FRIDAY...WHEN
A FEW OF THESE THUNDERSTORMS COULD BECOME STRONG OR EVEN SEVERE.
