AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 1231 AM EST TUE FEB 19 2013 .UPDATE... THE AVIATION SECTION HAS BEEN UPDATED BELOW && .SYNOPSIS... ISSUED AT 344 PM EST MON FEB 18 2013 A STRONG LOW PRESSURE SYSTEM MOVING THROUGH THE GREAT LAKES WILL BRING RAIN TO THE AREA THIS EVENING AND POTENTIAL FOR A RAIN SNOW MIX AND SOME SNOWFLAKES OVERNIGHT. WINDS WILL REMAIN STRONG THROUGH TUESDAY WITH A TIGHT PRESSURE GRADIENT OVER THE AREA. TEMPERATURES WILL DROP QUITE A BIT AFTER THE COLD FRONTAL PASSAGE OVERNIGHT AND AFTER SOME FLURRIES TUESDAY DRY WEATHER WILL BE IN PLACE UNTIL THURSDAY. A STRONG LOW PRESSURE SYSTEM ARRIVING THURSDAY WILL BRING A WINTRY MIX WITH SOME ICE POTENTIAL TO THE AREA THROUGH THURSDAY NIGHT AND INTO FRIDAY. TEMPERATURES SHOULD MODERATE WITH THE PASSAGE OF THE THURSDAY SYSTEM. && .NEAR TERM /TONIGHT/... ISSUED AT 1010 PM EST MON FEB 18 2013 RADAR TRENDS THIS EVENING ARE SHOWS IN COLD FRONT IN PLACE ACROSS EASTERN ILLINOIS...PUSHING EAST. PLENTIFUL RAINFALL WAS FOUND AHEAD OF THE FRONT OVER CENTRAL INDIANA. BASED UPON RADAR TRENDS PRECIPITATION WILL END OVERNIGHT AS THE FRONT PASSES TO OUR EAST. 00Z 850MB ANALYSIS SHOWS STRONG CAA POISED TO PUSH INTO INDIANA IN THE WAKE OF THE FRONT WITH 850MB TEMPS OF LESS THAN -8C POISED TO ARRIVE BY DAYBREAK. WITH SURFACE TEMPS UPSTREAM ALREADY IN THE LOWER 20S AND EVEN THE TEENS IN EAST CENTRAL IA...HAVE TRENDED LOW TEMPS COOLER. LIGHTNING DETECTION DATA FAILS TO SHOW ANY STRIKES IN OR NEAR THE STATE. HAVE REMOVED THUNDER ALSO. && .SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/... ISSUED AT 344 PM EST MON FEB 18 2013 COLD AIR WILL STREAM IN IN THE WAKE OF THE COLD FRONTAL PASSAGE. THERE MAY BE A STRAY SNOW SHOWER OR TWO LEFT IN THE EAST TO BEGIN THE DAY TUESDAY AS THE LOW PRESSURE SYSTEM LIFTS NORTHEAST AWAY FROM THE GREAT LAKES. A TIGHT PRESSURE GRADIENT WILL REMAIN ACROSS THE AREA AND ANOTHER DAY WITH WIND GUSTS IN THE 30-40 MPH RANGE WILL BE IN STORE...THIS TIME WITH MUCH COLDER TEMPERATURES ON NORTHWESTERLY WINDS. ALTHOUGH MEASURABLE SNOW IS NOT ANTICIPATED...WITH THE PASSAGE OF THE UPPER TROUGH AND COLD AIR ALOFT EXPECT TO SEE SOME FLURRIES AROUND THE AREA THROUGH THE MORNING HOURS...AND THESE COULD CONTINUE ACROSS THE NORTH THROUGHOUT THE DAY. TUESDAY NIGHT EXPECT SKIES TO START CLEARING OUT AND WINDS TO DROP OFF AS PRESSURE GRADIENT WEAKENS. WITH ALL THE COLD ADVECTION FROM EARLIER IN THE DAY EXPECT TEMPERATURES TO PLUMMET INTO THE SINGLE DIGITS TO MID TEENS. WEDNESDAY WILL SEE AMPLE SUNSHINE BUT 850 MB TEMPERATURES REMAIN COLD. TEMPERATURES WILL STRUGGLE TO REBOUND AND HIGHS SHOULD MAX OUT IN THE 20S WITH LOW 30S IN THE SOUTH...WHICH WAS A GUIDANCE AVERAGE. FOR WEDNESDAY NIGHT WARM ADVECTION WILL BEGIN IN EARNEST BUT SKIES WILL REMAIN MOSTLY CLEAR SO LOWS SHOULD BE IN THE TEENS TO AROUND 20 WHICH WAS REFLECTED WELL BY THE MODEL CONSENSUS. && .LONG TERM /THURSDAY THROUGH MONDAY/... ISSUED AT 246 PM EST MON FEB 18 2013 MAIN FOCUS FOR THE EXTENDED REMAINS ON POTENTIAL FOR A WINTRY MIX WITH STORM MOVING THROUGH THE REGION THURSDAY AFTERNOON AND NIGHT WITH CHANCES FOR ADDITIONAL PRECIP RETURNING FOR EARLY NEXT WEEK. ACTIVE AND AMPLIFIED PATTERN ALOFT SETTING UP THROUGH THE PERIOD. MODEL GUIDANCE REMAINS GENERALLY CONSISTENT WITH THE MAIN FEATURES ASSOCIATED WITH LOW PRESSURE TRACKING OUT OF THE CENTRAL PLAINS AND OCCLUDING OVER THE MID MISSISSIPPI VALLEY EARLY FRIDAY. THE DETAILS HOWEVER REMAIN MURKY AS THE COMPLICATING FACTORS PRESENTED BY DRY AIR AND ITS IMPACTS ON PRECIP COVERAGE AND INTENSITY...AND SURFACE TEMPS AND THEIR IMPACT ON PRECIP TYPE. AS THE LOW OCCLUDES AND WEAKENS THURSDAY NIGHT...MAJORITY OF THE MODELS CONTINUE TO ADVERTISE A SPLITTING OF DEEPER MOISTURE TOWARDS THE UPPER LOW TO THE NORTHWEST AND ALONG THE OCCLUDED FRONT SOUTH OF THE FORECAST AREA IN THE VICINITY OF A NEW SURFACE WAVE. REMAIN CONCERNED THAT PRESENCE OF DRY AIR AND PERSISTENT EASTERLY FLOW AHEAD OF THE FRONT WILL IMPEDE PRECIP ONSET UNTIL THURSDAY AFTERNOON...AND WILL LIKELY LIMIT PRECIP ACCUMS AS THE LOWER LEVELS MOISTEN UP. SOUNDING DATA REMAINS CONSISTENT IN FAVORING LIGHT SNOW AND POSSIBLY SLEET AS MAIN PRECIP TYPES THROUGH 00Z FRIDAY. SURGE OF WARMER AIR THROUGH THE BOUNDARY LAYER NOT AS STRONG AND SLOWER THAN PREVIOUS RUNS INDICATED. TO ACCOUNT FOR THE SLIGHTLY COOLER BOUNDARY LAYER CONDITIONS... HAVE HELD ONTO SNOW AND SLEET MENTION OVER NORTHERN COUNTIES THROUGH THE EVENING WITH FREEZING RAIN DEVELOPING THEREAFTER. PRECIP SHOULD TRANSITION INCREASINGLY TOWARDS FREEZING RAIN ACROSS THE I-70 CORRIDOR WITH POSSIBILITY FOR A CHANGE TO ALL RAIN OVER FAR SOUTHERN COUNTIES AS SURFACE TEMPS REACH AND WARM PAST 32F LATE THURSDAY NIGHT. AMOUNTS REMAIN GREATLY IN QUESTION DUE TO THE POTENTIAL IMPACTS WITH DRIER AIR ALOFT AS THE FRONT PASSES...BUT POTENTIAL FOR A LIGHT ICE ACCUMULATION IS POSSIBLE OVER MUCH OF THE AREA. ALSO COULD SEE AN INCH OR SO OF SNOW ACCUM OVER NORTHERN COUNTIES. SURFACE TEMPS WILL WARM ABOVE 32F OVER ENTIRE FORECAST AREA FRIDAY WITH ANY LINGERING PRECIP FALLING AS LIGHT RAIN AND/OR DRIZZLE. WILL SEE CLOUDS PERSIST INTO SATURDAY AS A SURFACE WAVE PASSES TO THE SOUTHEAST OF THE REGION ALONG THE REMNANT FRONT. YET ANOTHER STRONG UPPER LOW SET TO EJECT OUT INTO THE CENTRAL PLAINS BY EARLY NEXT WEEK AND LOOKS POISED TO SEND OUT ANOTHER OCCLUDED SURFACE LOW INTO THE MIDWEST. WILL INTRODUCE LOW CHANCES FOR RAIN MONDAY. TEMPS WILL BE NEAR TO JUST ABOVE NORMAL OVER THE WEEKEND. && .AVIATION /DISCUSSION FOR THE 19/0600Z TAF ISSUANCE/... ISSUED AT 1230 AM EST TUE FEB 19 2013 MVFR CONDITIONS TO CONTINUE OVERNIGHT BEFORE GRADUALLY IMPROVING BY TUESDAY AFTERNOON. WIND GUSTS OF 25-30 KTS ARE EXPECTED TO CONTINUE AS A 70+ KT 850 MB JET MOVES ACROSS THE REGION. AS OF ISSUANCE TIME...THE COLD FRONT AND ASSOCIATED WIND SHIFT SHOULD HAVE JUST PASSED THROUGH KLAF AND IS EXPECTED TO PASS THROUGH ALL TERMINALS BY 07Z. PRECIPITATION ASSOCIATED WITH THIS FRONT IS MOVING QUICKLY FROM WEST TO EAST WITH THE BACK EDGE ALONG THE INDIANA/ILLINOIS STATE LINE AS OF 06Z. WITH WINDS SWITCHING TO THE NORTHWEST WITH FRONTAL PASSAGE...MUCH COLDER AIR WILL BE USHERED INTO THE REGION WITH -RA GRADUALLY TRANSITIONING TO -SN. HOWEVER...HAVE TRENDED TOWARDS MORE OF JUST FLURRIES WITHOUT ANY MAJOR VISIBILITY RESTRICTIONS WITH PRECIPITATION EXPECTED TO END NOT TOO LONG AFTER FRONTAL PASSAGE. PRECIPITATION SHOULD MOVE OUT OF ALL THE TERMINALS BY SUNRISE TUESDAY MORNING WITH STRONG NORTHWEST WINDS AND GUSTS TO 30 KTS CONTINUING. && .IND WATCHES/WARNINGS/ADVISORIES...NONE. && SYNOPSIS...CP NEAR TERM...PUMA SHORT TERM...CP LONG TERM....RYAN AVIATION...LEE
