NATIONAL WEATHER SERVICE ST LOUIS MO
644 AM CDT MON MAR 18 2013

.SHORT TERM...(THROUGH LATE THIS AFTERNOON)
ISSUED AT 315 AM CDT MON MAR 18 2013

SURFACE LOW OVER WESTERN TN AS OF 07Z...WILL CONTINUE TO LIFT
NORTHEAST TODAY. MOST OF FORECAST AREA TO SEE SOME LINGERING
ISOLATED RAIN/DRIZZLE THIS MORNING. HOWEVER...MODELS AND REGIONAL
RADAR SHOWING SECONDARY SHORTWAVE OVER EASTERN KANSAS SLIDING
NORTHEAST THROUGH NORTHERN MO TODAY. SO COULD SEE SOME SHOWERS
DEVELOPING OVER CENTRAL/NORTHEAST MO...WEST CENTRAL IL THIS MORNING
BEFORE EXITING TO OUR NORTHEAST BY MIDDAY. OTHERWISE...CLOUDS TO
SLOWLY CLEAR OUT FROM WEST TO EAST MAINLY DURING THE AFTERNOON HOURS
WITH GUSTY WEST TO NORTHWEST WINDS BEHIND THIS WEATHER SYSTEM.
EXPECT GUSTS NEAR 25 MPH AT TIMES OVER NORTHERN PORTIONS OF FORECAST
AREA. HIGH TEMPERATURES WILL BE IN THE MID 40S TO LOW 50S.

.LONG TERM...(TONIGHT THROUGH SUNDAY)
ISSUED AT 315 AM CDT MON MAR 18 2013

(TONIGHT-WEDNESDAY)

NW FLOW ALOFT WILL PERSIST OVER THE REGION THROUGH MIDWEEK AS UPPER
LOW SLOWLY DRIFTS ACROSS THE GREAT LAKES REGION.   MAIN CONCERN
DURING THIS TIME IS FAST-MOVING SHORTWAVE...CLIPPERY LOOKING SYSTEM
THAT WILL ZIP THROUGH THE REGION TUESDAY AFTERNOON AND TUESDAY
EVENING.  LOW LEVEL AMS IS EXTREMELY DRY AS THE DYNAMICS WITH THIS
FEATURE FIRST BEGIN TO IMPACT OUR AREA AND CERTAINLY AT FIRST ANY
PRECIP THREAT WILL BE LIMITED TO A FEW SPRINKLES.  HOWEVER...THERE
IS CONSENSUS IN THE NAM...GFS...AND SREF THAT A SOMEWHAT ROBUST
BUT BRIEF SHOT OF WAA IN ADVANCE OF THE SHORTWAVE MAY BE ENOUGH
MOISTEN THE LOWER LEVELS AND GET A SMALL AREA OF MEASURABLE RAIN
GOING TUESDAY EVENING OVER S SECTIONS OF THE CWA. MOST IF NOT ALL
OF THIS PRECIP SHOULD EXIT BY 06Z WEDNESDAY...FOLLOWED BY ANOTHER
SE SURGE OF CANADIAN AIR ON WEDNESDAY.

TEMPS ON TUESDAY SHOULD BE SIMILAR TO THOSE OF TODAY...BUT THE
REINFORCING SHOT OF COLD AIR ON WEDNESDAY SHOULD SEND HIGHS BACK
INTO THE 30S AND LOWER 40S.

(THURSDAY-SUNDAY)
A VERY ATYPICAL LATE MARCH UA PATTERN IS FORECAST FOR THE CONUS.
UPPER LEVEL LOW OVER THE GREAT LAKES WILL COMBINE WITH SEVERAL OTHER
DISTURBANCES TO DO-SI-DO THEIR WAY FROM THE GREAT LAKES INTO THE
CANADIAN MARITIMES...WHILE A SERIES OF SHORTWAVES DEEPEN TROF OVER
THE SOUTHWESTERN U.S. NET EFFECT IS THAT MAIN BELT OF WESTERLIES
WILL REMAIN WELL SOUTH OF OUR AREA.

PATTERN IS CERTAINLY A QUIRKY ONE...AND NOT SURE HOW HEAVILY TO LEAN
ON ANY ONE SOLUTION.  THERE DOES SEEM TO BE SOME AGREEMENT THAT A
PERSISTENT RETURN FLOW WILL SET UP ON THE BACK SIDE OF SLOWLY
RETREATING SURFACE RIDGE.  THIS LIFT...WHICH AT TIMES SHOULD BE
AIDED BY SHORTWAVE ENERGY EMBEDDED IN THE WESTERLIES...WILL BRING A
THREAT OF SOME LIGHT PRECIP ON THURSDAY THROUGH FRIDAY...ESPECIALLY
OVER THE SOUTHWEST HALF OF THE CWA. FOR NOW HIGHEST POPS IN OUR
AREA REMAIN IN THE CHANCE CATEGORY...AS STRONGEST LIFT SHOULD
REMAIN SOUTHWEST OF OUR FA.

TEMPERATURES WILL BE REMAINING WELL BELOW NORMAL THROUGHOUT THE
LAST HALF OF THE WEEK AS THE UA PATTERN KEEPS SPRINGTIME WARMTH
SUPPRESSED TO OUR SOUTH.
