Area forecast discussion, Apr 27, 2:45 AM EDT, 35 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 245 AM EDT MON APR 27 2009 .DISCUSSION... FOCUS ON THE FCST IS ON WINDS/TEMPS AND PRECIP CHCS TODAY AND MAINLY PRECIP CHCS THEREAFTER THROUGH WEDS. ONLY MINOR DIFFERENCES NOTED WITH MOS GUIDANCE FOR TEMPS/PRECIP TODAY AND TONIGHT. CURRENT TEMP/PRECIP FCST REMAINS WITHIN THE ENVELOPE OF BOTH THE GFS/NAM THROUGH THE FIRST 48 HRS. ALL IN ALL EXPECT TO MAKE ONLY MINOR CHANGES TO THE FCST THROUGH WEDS WITH NO CHANGE THEREAFTER. 6Z SFC MAP SHOWED A 1005MB LOW ACROSS NW WI WITH A SECONDARY LOW ACROSS THE OK PANHANDLE. A SLOW MOVING COLD FRONT WAS LOCATED ACROSS CENTRAL IA INTO KS. WATER VAPOR SAT LOOP SHOWS ONE UPPER WAVE LIFTING INTO THE DAKOTAS WITH ANOTHER NOW MOVING INTO KS. THE STRONGEST WAVE APPEARED TO BE LOCATED ACROSS UT/CO. TODAY...DRY AIR ALONG THE WESTERN PERIPHERY OF STRONG SFC/UPPER HIGH PRESSURE ACROSS THE EASTERN U.S. WILL CONTINUE TO KEEP SFC DEWPOINTS IN THE LOW TO MID 50S WHICH ALONG WITH POOR MID LVL LAPSE RATES SHOULD KEEP STRONGER INSTABILITY WEST OF THE AREA. BOTH GFS/NAM SHOW SOME DYNAMIC LIFT AHEAD OF THE UPPER TROUGH THIS AFTERNOON. CURRENT FCST FOR HIGHER PRECIP CHCS NEAR IL LATE THIS AFTERNOON APPEAR REASONABLE AND WILL KEEP AS IS. CURRENT DAYTIME MAX TEMPS ALSO AGREE WELL WITH LATEST MOS TEMPS. MAIN ISSUE TODAY MAY BE WINDS WHICH COULD GUST TO 45 MPH FOR A BRIEF TIME THIS MORNING INTO EARLY AFTERNOON AS THE LLJ TRACKS ACROSS PARTS OF THE REGION. I WILL ISSUE A WIND ADVISORY FOR THE NW HALF OF THE CWA DUE TO THE POTENTIAL FOR GUSTS TO AROUND 45 MPH MAINLY NW OF IND TODAY. TONIGHT...SUPPORT FOR PRECIP WILL INCREASE ALOFT AS THE RIGHT ENTRANCE REGION OF THE UPPER JET MOVES ACROSS THE AREA. SCATTERED SHOWER AND THUNDERSTORM ACTIVITY WILL OCCUR WITHIN THE 850MB THETAE RIDGE AND LIKELY PRECIP CHCS LOOK GOOD ESPECIALLY AFTER 06Z. SVR THREAT APPEARS MINIMAL DUE TO LIMITED CAPE DESPITE INCREASING DEEP LAYER SHEAR. TUES...SCATTERED SHOWERS AND TSRA SHOULD PERSIST THROUGH MIDDAY BEFORE DECREASING IN COVERAGE AS THE UPPER TROUGH WEAKENS AND PULLS AWAY FROM THE REGION. MOS TEMPS ARE SIMILAR AND WILL USE A BLEND. WEDS AND BEYOND...QUIET CONDS SHOULD OCCUR WEDS BEFORE ANOTHER SYSTEM IMPACTS THE AREA THU-FRI. IF THE GFS IS CORRECT WE COULD SEE SOME SVR POTENTIAL BY FRI AS A STRONG WAVE AND COLD FRONT MOVE ACROSS THE REGION. && .AVIATION DISCUSSION...FOR THE 06Z TAFS MAIN PROBLEM FOR AVIATION WILL BE WINDS BECOMING GUSTY AFTER SUNRISE THEN THUNDERSTORMS LATE IN THE FORECAST PERIOD. TAFS WILL START OUT WITH LOW PRESSURE OVER MN. A STATIONARY FRONT EXTENDS EAST OF THE LOW INTO THE GREAT LAKES WITH A COLD FRONT EXTENDING TO THE SOUTH. THE TIGHT PRESSURE GRADIENT ALONG WITH DAYTIME HEATING WILL CAUSE STRONG WINDS TO MIX DOWN. WIND GUSTS TO 35 KTS ARE POSSIBLE AFTER 15Z. THE LOW WILL MOVE TO THE NE ON MONDAY. AT 00Z THE COLD FRONT WILL EXTEND THROUGH NORTHERN IL INTO CENTRAL MO. MOISTURE WILL QUICKLY INCREASE AS THE FRONT MOVES CLOSER TO INDIANA. SCATTERED THUNDERSTORMS WILL MOVE INTO THE LAF AREA AFTER 20Z THEN INTO THE REST OF THE TAFS FROM 00Z-04Z. THE PRECIPITATION COVERAGE WILL INCREASE AFTER 01Z IN LAF AND AFTER 05Z IN REST OF TAFS. CONDITIONS WILL DECREASE TO MVFR IN SHOWERS AND THUNDERSTORMS. THE CONDITIONS FOR SEVERE THUNDERSTORMS ARE LIMITED BUT STRONG THUNDERSTORMS ARE POSSIBLE. && .IND WATCHES/WARNINGS/ADVISORIES...WIND ADVISORY NW HALF TODAY. && AVIATION...SH PUBLIC...CO
