AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
125 PM CDT THU APR 5 2007

.UPDATE...

NARROW BUT INTENSE BAND OF SNOW ASSOCIATED WITH THE MID LEVEL
FRONTOGENESIS CONTINUES TO BUILD SOUTHWARD. NUMEROUS OBSERVATIONS
FROM WITHIN THE BAND INDICATE VSBYS DROPPING TO 1/2SM OR LOWER
(INCLUDING ONE AT ZERO VISIBILITY IN KOGA IN SW NE). APPEARS AS
THOUGH THE INTENSITY OF THE SNOW IS COMPENSATING FOR THE WARM GROUND
WITH LSRS STREAMING IN FROM WFO ICT OF ACCUMULATIONS. BEGINNING TO
THINK AN INCH OR SO OF ACCUMULATION IS POSSIBLE AND AM LEANING
TOWARD ISSUING A SHORT FUSE SNOW ADVISORY FOR OUR SW MOST CWA. WILL
TAKE A LOOK AT A BIT MORE DATA AND HOPEFULLY HAVE A DECISION MADE
AND SOMETHING OUT BEFORE 1900 OR 1930 UTC.

.UPDATE...//ISSUED AT 1111 AM CDT THU APR 5 2007//

GROWING INCREASINGLY CONCERNED THAT WE COULD SEE A BURST OF SNOW
THIS EVENING OVER MAINLY OUR SOUTHWESTERN CWA.

WATER VAPOR IMAGERY AND REGIONAL PROFILER NETWORK BOTH SHOW A RATHER
COMPACT BUT PRONOUNCED SHORTWAVE EMERGING ONTO THE CENTRAL HIGH
PLAINS EARLY THIS MORNING. THIS FEATURE SHOULD CONTINUE TO RIDE THE
WNW FLOW AND RAPIDLY APPROACH THE AREA BY VERY LATE THIS AFTERNOON
INTO EARLY THIS EVENING. WHILE MOISTURE WILL BE LIMITED...BAND OF
STRONG FORCING IN ASSOCIATION WITH MID LEVEL FRONTOGENESIS IN
CONJUNCTION WITH WEAK STATIC STABILITY SHOULD BE SUFFICIENT TO
OVERCOME THE DRY LOW LEVELS AND ALLOW FOR TOP DOWN SATURATION AND A
A BAND OF PRECIPITATION TO AFFECT OUR SOUTHWESTERN CWA.

WET BULB TEMPS THROUGH THE DEPTH OF OUR SOUNDING THIS MORNING WERE
WELL BELOW FREEZING AND FORECAST SOUNDINGS THIS EVENING ARE ALSO
SUPPORTIVE OF ALL SNOW. GIVEN THE PRESENCE OF FRONTOGENETIC BAND AND
WEAK STABILITY COULD SEE A RATHER NARROW...BUT SOMEWHAT INTENSE BAND
SNOW SET UP. WARM SOIL/GROUND TEMPS SHOULD PREVENT ACCUMULATION
EXCEPT ON SOME ELEVATED OBJECTS...HOWEVER SNOW COULD BRIEFLY FALL
RATHER HEAVILY AT TIMES THIS EVENING LEADING TO REDUCED VISIBILITIES.

HAVE UPDATED GRIDS/DERIVED PRODUCTS AND WILL UPDATE HWO SHORTLY.

.DISCUSSION...

TEMPERATURES EARLY THIS MORNING WERE STILL IN THE LOWER AND MID 30S
AS OF 2 AM...WITH DEWPOINT TEMPS IN THE LOWER AND MID 20S. NORTHWEST
WINDS OF 5 TO 8 KNOTS HAVE KEPT TEMPERATURES FROM DROPPING TOO
QUICKLY. HOWEVER...EVEN WITH A SLOWER FALL...READINGS SHOULD DROP
AND REMAIN BELOW FREEZING FOR AT LEAST SEVERAL HOURS BETWEEN NOW AND
MID MORNING.

TO OUR WEST...WERE ALREADY SEEING INCREASED CLOUD COVER OVER THE
HIGH PLAINS AS A WELL ADVERTISED UPPER DISTURBANCE DROPS SOUTHEAST
OUT OF THE NORTHERN ROCKIES. NOT SEEING MUCH PRECIP FROM SURFACE OBS
OVER EASTERN COLORADO/WESTERN NEBRASKA YET...AND EXPECT SYSTEM TO
REMAIN MOISTURE CHALLENGED AS IT DROPS ACROSS THE CENTRAL/SOUTHERN
PLAINS TONIGHT. DECENT LIFT ON THE 305K AND 315K SURFACES SUGGEST
THAT ENOUGH MOISTURE MAY BE SQUEEZED OUT TO CARRY AT LEAST SOME
LOWER END CHANCE PROBABILITIES. THERMAL PROFILES CONTINUE TO SHOW
RAIN DURING THROUGH LATE AFTERNOON WITH POTENTIAL FOR A WINTRY MIX
TONIGHT.

A REINFORCING SHOT OF EVEN COLDER AIR WILL SURGE SOUTHWARD FRIDAY
NIGHT...DROPPING 850 MB TEMPERATURES INTO THE NEGATIVE MID TEENS
CELSIUS. EVEN WITH FULL SUN AND DEEP MIXING...SURFACE TEMPS WILL
STRUGGLE TO REACH THE LOWER AND MID 40S WE CURRENTLY HAVE GOING.
LATEST MOS GUIDANCE SHOWS SURFACE TEMPS POTENTIALLY FALLING INTO THE
MID AND UPPER TEENS BY EARLY SATURDAY MORNING. ONLY NEGATIVE FACTOR
FOR TEMPERATURES COMPLETELY TANKING WILL BE WINDS REMAINING UP
AROUND 10 MPH. FOR NOW WILL GO WITH UPPER TEENS TO LOWER 20S FOR
FRIDAY NIGHT AND SATURDAY NIGHT.

THE AIRMASS IS EXPECTED TO SLOWLY MODERATE BY SUNDAY AND MONDAY WITH
AFTERNOON HIGHS ROCKETING BACK INTO THE 50S AND 60S. UPPER LEVEL
HEIGHT PATTERN FLATTENS OUT AS UPPER LOW OVER NEW ENGLAND LIFTS
NORTHEAST INTO NOVA SCOTIA. AN INTENSIFYING UPPER TROUGH OVER THE
SOUTHWEST U.S. EARLY NEXT WEEK IS EXPECTED TO TRAVERSE OUR AREA BY
TUESDAY NIGHT AND WEDNESDAY.

.AVIATION...

FOR THE 18Z TAFS...AN UPPER LEVEL DISTURBANCE WAS HELPING TO PRODUCE
SOME LIGHT TO MODERATE SNOW ACROSS THE CENTRAL AND NORTHERN PLAINS.
CLOUDS WERE JUST TO THE WEST OF THE JLN TERMINAL LOCATION AND HAVE
MID LEVEL CLOUDS MOVING IN AT THE BEGINNING OF THE 18Z TAF CYCLE.
MAY TAKE AWHILE TO SATURATE DOWN AND HAVE CEILINGS GRADUALLY
DROPPING DURING THE AFTERNOON TO AROUND 5000 FEET TOWARDS THE LATE
AFTERNOON AND 3000 FEET BY THE EARLY EVENING.  HAVE LIGHT SNOW
BEGINNING TOWARDS 00Z AT JLN AND 02Z AT SGF WITH A TEMPORARY
CEILINGS AROUND 2000 FEET AND VISIBILITIES FROM 1 TO 2 MILES WITHIN
THE HEAVIER SNOW.  SHOULD BE A QUICK MOVING SYSTEM WITH ANY SNOW
ENDING BY 06Z AND CEILINGS RISING BACK TO AROUND 5000 FEET IN THE
OVERNIGHT HOURS.
