AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
1122 AM CST SUN MAR 2 2014

...UPDATED FOR AVIATION DISCUSSION...

.SHORT TERM...(TODAY THROUGH TUESDAY)
ISSUED AT 327 AM CST SUN MAR 2 2014

TODAY-EARLY EVENING:
EXPECT SOME MARGINALLY CONVECTIVE PRECIPITATION TO PERSIST FOR A
BIT LONGER IN SOUTHEAST KS WHILE SECOND BAND THROUGH ICT WILL
LIKELY RE-INTENSIFY LATER THIS MORNING. ONE POSITIVE IS THAT THE
FREEZING PRECIPITATION APPEARS TO BE OVER AS COLD AIR HAS RESULTED
IN EITHER SLEET/SNOW FOR THE LAST SEVERAL HOURS. A BIT PUZZLED BY
CONFLICTING SIGNALS WITH APPROACHING WAVE...WITH LESS THAN
IMPRESSIVE 0000 UTC UPPER AIR DATA...BUT IMPRESSIVE WATER VAPOR
LOOP AND FAIR AMOUNT OF DISCREPANCIES BETWEEN MODELS ON
TIMING/LOCATION OF BEST LIFT DURING THE DAY. HOWEVER CONSISTENT
SIGNAL IS THAT SOUTH CENTRAL/SOUTHEAST KS WILL LIKELY HAVE
MULTIPLE CHANCES OF SNOW FOR ANOTHER 12 PLUS HOURS...EITHER FROM
SYNOPTIC SCALE LIFT WITH WAVE AND/OR FRONTOGENESIS. EVEN IF THE
INTENSITY IS LESS...PERSISTENCE SHOULD STILL RESULT IN AT LEAST
2-3 MORE INCHES BARRING A PREDOMINATELY SLEET EVENT. HAVE
DOWNGRADED SALINE/ELLSWORTH TO AN ADVISORY WHERE ONLY LIGHT SNOW
IS ANTICIPATED. HAVE ALSO EXTENDED THE WINTER STORM WARNING FOR
COWLEY COUNTY THROUGH THIS EVENING...AS PRECIPITATION WILL LIKELY
CONTINUE PAST 0000 UTC.

REST OF TONIGHT-MON:
RAPID CLEARING IS EXPECTED DURING THE NIGHT WITH WINDS CONTINUING
TO DIMINISH. WITH IDEAL RADIATIONAL COOLING...EXPECT TEMPERATURES
TO TANK... WITH SOME RECORD LOWS PROBABLY FALLING. GIVEN RIDGE
AXIS MOVING ACROSS AND LIGHT WINDS...TEMPERATURE RECOVERY WILL BE
DIFFICULT ON MONDAY...ESPECIALLY IF CIRRUS IS THICKER THAN
CURRENTLY EXPECTED. GFS/ECMWF AT ODDS WITH TIMING/LOCATION OF HIGH
LEVEL MOISTURE ASSOCIATED WITH ANOTHER RIPPLE IN THE UPPER FLOW.

MON NIGHT-TUE:
ANOTHER COOL NIGHT...BUT RETURN FLOW MAY LIMIT TEMPERATURE DROP
ACROSS FAR WEST. STILL KEPT TEMPERATURES COOL IN THE EAST...WITH A
NOD TO THE GEM WHICH HAS VERIFIED WELL IN THIS REGIME. MODEST
WARMUP ON TUE AS SOUTH WINDS INCREASE...ALTHOUGH TEMPERATURES
STILL RUNNING A BIT BELOW NORMAL. -HOWERTON

.LONG TERM...(WEDNESDAY THROUGH SATURDAY)
ISSUED AT 327 AM CST SUN MAR 2 2014

MEDIUM RANGE CONSENSUS CONTINUES TO SUGGEST A WEAK/MODEST
SHORTWAVE TROUGH WILL PROGRESS OVER MID-AMERICA MID-WEEK...WITH AN
ACCOMPANYING CHANCE OF A LIGHT WINTRY PRECIPITATION WED-WED NIGHT.
UPPER DYNAMICS ARE LACKING WITH THIS FEATURE AND TEMPERATURES MAY
BE ONLY MARGINALLY COLD ENOUGH FOR SNOW...SO NOT ANTICIPATING A
BIG WEATHER-MAKER...WITH ONLY VERY MINOR ACCUMULATIONS POSSIBLE.
SHORTWAVE RIDGING ENCROACHES FROM THE WEST BY LATE
WEEK...RESULTING IN WARMING TEMPERATURES FOR THU-FRI...WITH 40S-
50S A GOOD BET AND POSSIBLY NEAR 60F OVER SOUTHERN KS FRI. ECMWF
AND GEM MODELS CONTINUE TO PROGRESS A MODEST MID-LEVEL TROUGH INTO
THE AREA BY THE WEEKEND...ALONG WITH AN ASSOCIATED COLD
FRONT...WHICH COULD SPELL ANOTHER ROUND OF WINTRY WEATHER AND
COLDER TEMPERATURES BY FRI NIGHT-SAT...ALTHOUGH LIKELY NOT NEARLY
AS COLD AS CURRENT AIRMASS. THIS SCENARIO DEFINITELY IS NOT SET IN
STONE YET THOUGH...AS GFS HAS BEEN CONSISTENTLY NOT AS AGGRESSIVE
WITH THIS SYSTEM AND THE ASSOCIATED COOL DOWN. NEEDLESS TO
SAY...QUITE A BIT OF UNCERTAINTY STILL EXISTS...SO STAY TUNED FOR
LATER FORECASTS.
