AREA FORECAST DISCUSSION...UPDATED AVIATION
NATIONAL WEATHER SERVICE ST LOUIS MO
639 AM CDT FRI APR 12 2013

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 320 AM CDT FRI APR 12 2013

THE VERTICALLY STACKED LOW CURRENTLY CENTERED IN THE VICINITY OF
NRN IOWA WILL MOVE NORTHEASTWARD INTO THE UPPER GREAT LAKES TODAY.
AN EXPANSIVE AND BROAD CYCLONIC CIRCULATION ASSOCIATED WITH THE
VORTEX WILL PERSIST ACROSS THE REGION TODAY WITH A CONTINUED FLUX
OF STRATUS AND ADDITIONAL STRATOCU DEVELOPING. THESE CONDITIONS
WILL RESULT IN ANOTHER COOL DAY WITH WELL BELOW AVERAGE HIGH
TEMPERATURES. THE SYSTEM WILL ONLY MEANDER A BIT NEWD TONIGHT
KEEPING A BROAD CYCLONIC FLOW ACROSS THE REGION. RH PROGS SUGGEST
THAT THE STRATUS SHOULD FINALLY CLEAR DURING THE EVENING HOURS.
WEAK HIGH PRESSURE ACROSS THE PLAINS WILL THEN SLIDE SEWD ACROSS
SW MO OVERNIGHT HOWEVER WSW SURFACE WINDS OF 4-8 KTS WILL PERSIST
ACROSS MUCH OF THE CWA. THIS WIND FLOW ALONG THE THE POTENTIAL FOR
AN INCREASE IN MID CLOUDS OVERNIGHT LEADS TO SOME UNCERTAINTY IN
THE POTENTIAL FOR SIGNIFICANT FROST AND MUCH LONGEVITY OF SUB-
FREEZING TEMPERATURES. AT THIS TIME I HAVE ONLY A SMALL PORTION
OF NE MO DROPPING BELOW FREEZING WITH PATCHY FROST FOR THE ENTIRE
AREA WITH LOWS IN THE 32-34 DEGREE RANGE. WILL LET THE DAY SHIFT
GET A BETTER LOOK TO ASSESS THE NEED FOR ANY FROST OR FREEZE HEADLINES.

.LONG TERM...(SATURDAY THROUGH THURSDAY)
 ISSUED AT 320 AM CDT FRI APR 12 2013

BIG CHANGES UNDERWAY DURING THIS PERIOD. THE WEAK HIGH PRESSURE
SYSTEM WILL SLOWLY RETREAT TO THE EAST ON SATURDAY AND HEIGHTS
ALOFT WILL BE ON THE RISE...RESULTING IN THE INITIAL STAGES OF
MODERATING TEMPERATURES. THE LOW LEVEL WAA REGIME WILL BEGIN TO
GET WELL UNDERWAY ON SATURDAY NIGHT AS A NEW SYSTEM MOVES INTO THE
PLAINS AND THE LOWER TROP FLOW STRENGTHENS CONSIDERABLY. A FEW
SPOTTY SHOWERS COULD RESULT ACROSS NE MO INTO WEST CENTRAL IL IN
RESPONSE. THERE SHOULD BE A BIG JUMP IN TEMPERATURES ON SUNDAY AS
STRONG SOUTHERLY FLOW TRANSPORTS WARM AIR AND MOISTURE INTO THE MS
VALLEY AHEAD OF THE ENCROACHING COLD FRONT. THESE ADVECTIONS AND
AN INCREASE IN MID LEVEL LAPSE RATES PRODUCE AN AXIS WEAK
INSTABILITY AND SUPPORT A CHANCE OF THUNDERSTORMS IN THE AFTERNOON
ACROSS NE MO ON THE LEADING EDGE OF DEEPER ASCENT. THE FRONT THEN
SETTLES SOUTHWARD SUNDAY NIGHT THROUGH MONDAY WITH AN INCREASING
CHANCE OF SHOWERS AND THUNDERSTORMS BOTH ALONG AND AHEAD OF THE
FRONT. INDICATIONS AT THIS TIME ARE THE FRONT WILL BECOME QUASI-
STATIONARY ACROSS THE SOUTHERN PORTION OF THE CWA THROUGH THE
FIRST HALF OF NEXT WEEK AS IT PARALLELS THE FLOW ALOFT. THIS WOULD
LEAD TO A STORMY PERIOD WITH PERSIST THUNDERSTORM CHANCES AS
DISTURBANCES WITHIN THE SW FLOW ALOFT TRAVERSE THE REGION AND
INTERACT WITH THE STALLED BOUNDARY.
