AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
647 AM CDT MON MAR 14 2011
...UPDATE TO AVIATION...
.UPDATE...
UPPER LOW IS BEGINNING TO PIVOT INTO THE AREA. WAT VAP IMAGERY
INDICATES A DRY SLOT WORKING INTO THE REGION. TEMPERATURES ACROSS
CENTRAL MISSOURI ARE RIGHT AROUND FREEZING...GIVE OR TAKE A DEGREE
OR TWO AND ONGOING SNOW HAS GENERALLY AMOUNTED TO AROUND TWO
INCHES. THERE ARE A FEW SPOTS WERE A HEAVIER POCKET OF SNOW HAS
PASSED OVER...AND THIS HAS RESULTED IN A FEW REPORTS OF AROUND
FOUR TO FOUR AND AND HALF INCHES.
AS WE MOVE INTO DAYLIGHT...LIGHT SNOW AND RAIN WILL CONTINUE TO
REDEVELOP OVER THE AREA. SHORT RANGE MODELS CONTINUE TO INSIST ON
A LOSS OF CLOUD ICE SO SNOW/RAIN MIX WILL GIVE WAY TO
RAIN/FREEZING DRIZZLE AS THE MORNING PROGRESSES. CLOSE ATTENTION
WILL NEED TO BE PAID TO CLOUD ICE THIS MORNING...PARTICULARLY
ACROSS CENTRAL MO. IF IT DOES NOT COME TO FRUITION...IT COULD SNOW
LONGER HERE.
DAYTIME ACCUMULATION OF WINTRY PRECIP WILL BE HIGHLY DEPENDENT ON
SNOWFALL RATES GIVEN MID MARCH INSOLATION. WITH AROUND TWO OR SO
INCHES ON THE GROUND ALREADY...AND TEMPERATURES WAVERING AROUND
FREEZING...SNOW MAY ACCUMULATE A BIT MORE ON GRASSY/ELEVATED
SURFACES. CERTAINLY GOING TO BE A FUN...RAW WEATHER DAY ACROSS THE
REGION.
GAGAN
&&
.DISCUSSION...
VERY COMPLEX AND FRANKLY UNCERTAIN FORECAST FOR THE SHORT TERM THIS
MORNING...AS INCREASINGLY IMPRESSIVE UPPER LEVEL GYRE MAKES ITS WAY
ACROSS THE REGION. MAIN FORECAST CONCERNS DURING THE NEXT 18 OR SO
HOURS WILL SETTLE ON PARTICULARITIES OF P-TYPE AND SURFACE
TEMPERATURE EVOLUTION.
RAIN WITH EMBEDDED THUNDER HAS CONTINUED EARLY THIS MORNING OUT
AHEAD OF THE MAIN UPPER LOW. DON'T HAVE TOO MANY CONCERNS ABOUT THE
"WARM SECTOR" OF THIS SYSTEM...AND THUNDER CHANCES SHOULD DECREASE
MARKEDLY BY DAYBREAK. MAIN CONCERN THEN RAMPS UP AS COOLER AND
SOMEWHAT DRIER AIR IS ADVECTED INTO THE REGION FROM THE NORTHEAST.
ANTICIPATE SEEING AREA OF SNOW CURRENTLY OVER CENTRAL AND
NORTHWESTERN MISSOURI/NORTHEASTERN KANSAS CONTINUE MOVE INTO THE EXTREME
NORTHERN PORTIONS OF THE CWA THROUGH DAYBREAK...WITH SOME
INTERMITTENT PERIODS OF MODERATE SN POSSIBLE THROUGH MID MORNING.
AS THE CORE OF THE UPPER LOW (AND THUS CORE OF COLD AIR ALOFT) MOVES
INTO THE AREA TODAY...WILL LIKELY SEE THE COLUMN COOL BELOW FREEZING
OVER THE ENTIRE CWA. HOWEVER...MODEL GUIDANCE THIS MORNING IS ALMOST
UNIVERSALLY IN AGREEMENT IN KEEPING MOST IF NOT ALL OF THE MOISTURE
WARMER THAN -10 TO -12 DEGREES C...AND AS A RESULT HIGHLY DOUBT THAT
CLOUD ICE WILL BE AVAILABLE OVER MOST OF THE CWA. WITH THAT IN
MIND...THINK THAT FALLING PRECIP WILL REMAIN IN LIQUID OVER MOST OF
THE CWA FROM MID/LATE MORNING ON.
END RESULT OF ABOVE EVOLUTION IN P-TYPE WILL LIKELY BE WIDESPREAD
DRIZZLE AND/OR LIGHT RAIN FALLING DURING THE DAYTIME HOURS AS A
MODIFIED TROWAL WRAPS INTO THE CORE OF THE UPPER LOW. AS ALLUDED TO
ABOVE...CONCERN THE BECOMES SURFACE TEMPERATURES. IF SURFACE TEMPS
STAY ABOVE FREEZING...THEN WINTRY PRECIP CONCERNS ESSENTIALLY BECOME
NIL. UNFORTUNATELY...PERSISTENT NORTH TO NORTHEAST FLOW WILL BE
ADVECTING IN SURFACE DEWPOINTS IN THE 28-32 DEGREE RANGE. AS
-RA/DRIZZLE FALL THROUGH THAT RELATIVE DRY AIR...EVAPORATIVE COOLING
EFFECTS MAY VERY WELL COOL SURFACE TEMPS TO OR BELOW
FREEZING...ESPECIALLY FOR ANY SHADED/SHELTERED AREAS. WHERE SURFACE
TEMPS CAN GET TO FREEZING OR BELOW...OBVIOUS CONCERN BECOMES EFFECTS
OF FREEZING DRIZZLE/LIGHT FREEZING RAIN.
CONSIDERING ALL THE ABOVE...HAVE GONE AHEAD AND HOISTED A WINTER
WEATHER ADVISORY FOR ROUGHLY U.S. 60 NORTH THROUGH 21Z...PRIMARILY
WITH FREEZING DRIZZLE IMPACTS IN MIND.
DRY AND WEAK COLD FROPA ON TUESDAY WILL JUST PUT A SMALL BUMP IN THE
ROAD TO A NICE WARM UP TOWARD THE END OF THE WEEK...AS PERSISTENT WAA
TAKES HOLD. ANOTHER FRONT LOOKS TO APPROACH FOR THE WEEKEND...AND
WHILE MOISTURE QUALITY WON'T BE GREAT...WILL HAVE AT LEAST A CHANCE OF A
FEW SCATTERED THUNDERSTORMS WITH THE FRONT IN THE AREA.

.AVIATION...
/ISSUED 647 AM CDT MON MAR 14 2011/
FOR THE 12Z TAF PACKAGE...IFR CIGS LOOK TO DOMINATE THIS ENTIRE
PERIOD AS WINDS HAVE BEGUN TO SHIFT TO A PREDOMINATELY NORTHERLY
DIRECTION. BIGGEST FORECAST CHALLENGE BY FAR WILL BE PRECIPITATION
TYPE TODAY. RAIN...SNOW AND EVEN FREEZING DRIZZLE IS POSSIBLE.
RAIN/SNOW WILL BE FAVORED THROUGH AT LEAST MID MORNING. THIS
SHOULD TRANSITION TO LIGHT RAIN AND DRIZZLE WITH PROSPECTS FOR
FREEZING DRIZZLE DEPENDENT ON SURFACE TEMPERATURES WHICH WILL
SLOWLY DROP TOWARD THE FREEZING MARK. WILL UPDATE THE FORECAST AS
NECESSARY BASED ON TEMPERATURE TRENDS. PRECIPITATION WILL END BY
THIS EVENING...BUT IFR CIGS WILL REMAIN. ANY VIS RESTRICTIONS...
MAINLY INTO THE MVFR RANGE...INTIMATELY LINKED TO PRECIPITATION.
