Area forecast discussion, Mar 20, 7:49 PM EDT, 6 hours 55 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
749 PM EDT SUN MAR 20 2011

.AVIATION...
VFR CONDITIONS PERSIST ACROSS THE AREA EARLY THIS EVENING WITH
FIRST BATCH OF SHOWERS AND ISOLATED THUNDERSTORMS HAVING TRACKED
EAST AND NORTH OF THE TERMINALS. REGIONAL RADAR MOSAIC IS
INDICATING RENEWED CONVECTIVE DEVELOPMENT ACROSS NORTH CENTRAL AND
NORTHWEST ILLINOIS AS UPPER TROUGH CONSOLIDATES ACROSS THE UPPER
MIDWEST. THIS UPPER LEVEL TROUGH WILL RACE EASTWARD TONIGHT AND
MAY LEAD TO THE DEVELOPMENT OF ADDITIONAL SCATTERED SHOWERS AND
ISOLATED THUNDERSTORMS ACROSS NORTHWEST AND NORTH CENTRAL INDIANA.
GIVEN THE EXPECTED TRACK OF THIS FORCING...THE MOST WIDESPREAD
COVERAGE OF THIS PRECIPITATION IS EXPECTED TO REMAIN NORTH OF THE
TERMINALS...BUT DID ADD A VCSH MENTION WITH CB CLOUD GROUP AT KSBN
FROM 03Z-06Z. SOUTHEAST WINDS WILL VEER TO THE SOUTH THIS
EVENING...WITH A WIND SHIFT TO THE WEST BY MORNING WITH COLD
FRONTAL PASSAGE. A PERIOD OF MVFR CIGS IS POSSIBLE JUST AHEAD AND
IN THE VICINITY OF THE COLD FRONT...BUT DRY AIR ADVECTION AND
SUBSIDENCE BEHIND THE FRONT SHOULD CLEAR ANY MVFR CIGS OUT AFTER
12Z. WILL MAINTAIN MENTION OF LLWS TONIGHT AS LOW LEVEL JET AXIS
AHEAD OF THIS TROUGH SHIFTS INTO THE AREA THIS EVENING.

.PREV DISCUSSION... /ISSUED 431 PM EDT SUN MAR 20 2011/

SHORT TERM...

TONIGHT THROUGH TUESDAY NIGHT

COMPACT BUT POTENT MID LEVEL IMPULSE CONTINUES TO ADVECT EAST ACROSS
THE NORTHERN PLAINS AND WILL TRAVERSE THE WESTERN GREAT LAKES
TONIGHT. FAIRLY STRONG POS THETA-E ADVECTION IN THE H925 TO H8 LAYER
UNDER VERY STEEP MID LEVEL LAPSE RATES CONTINUES TO SUPPORT A LARGE
AREA OF RAIN AND THUNDERSTORMS...WITH THE STRONGEST STORMS OVER NE
IL WHERE THE NOSE OF THE LL THETA-E RIDGE IS IN PLACE. PRIMARY AREA
OF SHRA/TS WILL CONTINUE TO SHIFT EAST ACROSS THE AREA WITH THE
HIGHEST COVERAGE ACROSS THE NORTH CLOSER TO STRONGER DYNAMIC LIFT.
TEMPS HAVE RECOVERED WELL ACROSS THE SOUTH INTO THE UPPER 50S AND
LOW 60S...WITH TEMPS STRUGGLING ACROSS THE FAR NORTH DUE TO RAINFALL
AND WETBULB PROCESSES...ALTHOUGH TEMPS ARE EXPECTED TO REBOUND
QUICKLY AS LL WINDS VEER THIS EVENING PER THE ADVANCING LL TROUGH.
POTENT 100+ KNOT UPPER LEVEL JET STREAK WILL RAPIDLY PUSH NORTH INTO
THE GREAT LAKES TONIGHT...WITH SIG PRESSURE FALLS BEING INDUCED OVER
CENTRAL MI. THIS WILL HELP SUPPORT A LL TROUGH INTO THE REGION
OVERNIGHT...WITH ANOTHER ROUND OF SCT SHRA/ISOLD TS POSSIBLE ALONG
AND AHEAD OF THIS FEATURE. HIGHEST POPS WILL EXIST ACROSS THE NORTH
AS LARGE SCALE LIFT WILL BE MAXIMIZED OVER MI. HAVE CONTINUED LIKELY
POPS ACROSS THE NORTH...BUT TRIMMED SOME GIVEN CONCERNS ON VEERING
LL WINDS...DECREASING OVERALL CONVERGENCE BEHIND THE INITIAL WEAK
IMPULSE NOW PROPAGATING THROUGH THE REGION. TEMPS WILL ACTUALLY RISE
AT MANY LOCATIONS OVERNIGHT AS WARM AIR SURGES INTO THE
REGION...WITH MOST AREAS REMAINING IN THE 50S ALL NIGHT. T FALLS
WILL SPREAD INTO THE WEST BY DAWN AS WINDS SHIFT W/NW OFF LK MI.

MON...DRIER AIR WILL ADVECT INTO THE REGION WITH NEUTRAL H925-H8
TEMP ADVECTION. DECREASING CLOUDS WITH DEEP MIXING WILL SUPPORT
TEMPS WELL INTO THE 60S SOUTHERN HALF...WITH NORTHERN AREAS SEEING A
STRONGER INFLUENCE FROM THE GREAT LAKES WITH COOLER READINGS.
EXPECTED LK MI GRAVITY FLOW PER LONG FETCH NORTHERLY FLOW BEHIND THE
SFC TROUGH WILL SUPPORT COLD CONDITIONS IN THE FAR NW...WITH TEMPS
POSSIBLY FALLING INTO THE UPPER 30S NEAR THE LAKE SHORE IN THE
AFTERNOON. HAVE TRIED TO INCORPORATE THIS IN THE GRIDS.

MON NIGHT THROUGH TUES NIGHT...FRONTAL BOUNDARY WILL STALL SOUTH OF
THE AREA MON...WITH ANOTHER POTENT UPPER WAVE AND ASSOCIATED SFC
REFLECTION EXPECTED TO EJECT INTO THE CENTRAL PLAINS...SUPPORTING
BACKING LL FLOW AND EVENTUAL POS THETA-E ADVECTION INTO THE
REGION. HAVE RETAINED LOW CHANCE POPS FOR THIS PROCESS MON NIGHT.
BOUNDARY WILL STRUGGLE NORTH TUES PER SFC PRESSURE FALLS INTO THE
REGION SUPPORTING A HEAVY BACKING OF THE LL WINDS. THIS WILL SUPPORT
CAA ACROSS THE NORTH...WITH A STRENGTHENING BAROCLINIC ZONE ACROSS
THE AREA...LIKELY INFLUENCE FROM THE GREAT LAKES HEAT SINK. FORECAST
MODELS DIFFER ON THE TRACK OF THE SFC LOW AND WARM FRONT
DETAILS...BUT WILL CONTINUE TO SIDE MORE TOWARDS A NAM/SREF SOLUTION
GIVEN TYPICAL BETTER HANDLING OF GREAT LAKES MESOSCALE INFLUENCES IN
THE SPRING. POTENT 80-90 KNOT MID LEVEL JET STEAK WILL LIKELY
SUPPORT A SEVERE WEATHER OUTBREAK WEST AND SW OF THE FA...WITH
POSSIBLE ELEVATED THUNDERSTORMS NORTH OF THE SFC WARM FRONT INTO THE
SOUTH...WITH A POTENTIAL FOR LARGE HAIL IN THE FAR SW BY LATE TUES.
HAVE RETAINED POP NUMBERS ATTM GIVEN THE POTENTIAL FOR ONE OR TWO
WAVES OF POSITIVE THETA-E ADV OVER THE ENTRENCHED COLD
WEDGE...SUPPORTING SHRA/S NORTH OF THE WARM FRONT. TEMPS WILL BE
QUITE TRICKY IN THE PERIOD WITH THERMAL FIELDS DICTATED BY THE
AMOUNT OF RAIN REALIZED AND DEGREE OF CAA FROM THE NORTH.

LONG TERM...

WEDNESDAY THROUGH SUNDAY.

ON WEDNESDAY...UPPER LEVEL TROUGH ACROSS NORTHERN PLAINS INTO THE
UPPER MIDWEST WILL APPROACH THE GREAT LAKES REGION AND WILL BEGIN TO
BE ABSORBED BY EASTERN CANADIAN UPPER LEVEL TROUGH. ISENTROPIC
ASCENT WILL SHIFT EAST INTO THE OHIO RIVER VALLEY EARLY WEDNESDAY WITH
LOW LEVEL COLD ADVECTION EXPECTED TO STRENGTHEN ACROSS THE LOCAL
AREA FOR WEDNESDAY AFTERNOON. ELONGATED WEST TO EAST DEFORMATION
FORCING WILL LIKELY KEEP RAIN GOING THROUGH WEDNESDAY AFTERNOON
BEFORE COMING TO AN END WEDNESDAY NIGHT. THICKNESS PROFILES MAY
SUPPORT A MIX OF RAIN/SNOW SHOWERS BEFORE PRECIP COMES TO AN END
WEDNESDAY NIGHT. SURFACE HIGH WILL BUILD SOUTHWARD ACROSS THE GREAT
LAKES REGION ON THURSDAY WITH MUCH COOLER CONDITIONS AND HIGHS IN
THE MID TO UPPER 30S. FOR THE END OF THE WEEK...FORECAST AREA MAY BE
PRONE TO SOME OVERRUNNING PRECIP CHANCES...ALTHOUGH A LARGE SPREAD
IN MEDIUM RANGE MODEL SOLUTIONS REGARDING EVOLUTION OF LEAD IMPULSES
FROM AMPLIFED EASTERN PACIFIC TROUGH LENDS TO SOMEWHAT LOW FORECAST
CONFIDENCE AT THIS TIME IN REGARDS TO INSERTING ADDITIONAL POPS LATE
THIS WEEK INTO THE WEEKEND. TEMPERATURES LIKELY TO REMAIN BELOW
NORMAL THROUGH THE END OF THE PERIOD WITH SHALLOW LEVEL COOLER AIR
LIKELY LINGERING THROUGH MUCH OF THE PERIOD.
