AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 636 AM EST FRI DEC 22 2006 .AVIATION... DISCUSSION FOR 12Z TAFS. SURFACE LOW CURRENTLY IN WEST CENTRAL ILLINOIS IS EXPECTED TO LIFT OVER KORD AND INTO THE UPPER PENINSULA BY 00Z. RAIN...IFR CIGS AND VSBYS WILL CONTINUE FOR SEVERAL MORE HOURS. A VERY PRONOUNCED DRY SLOT OUT TO THE WEST WILL PUSH IN AROUND 18Z AND THIS SHOULD QUICKLY END THE LOW CEILINGS AND VSBY AND PROVIDE VFR CONDITIONS AFTER 18-21Z. OVERNIGHT THESE VFR CONDITIONS SHOULD CONTINUE. CONSIDERED THE POSSIBILITY OF FOG OVERNIGHT BUT NOT COMPLETELY FAVORABLE CONDITIONS...SO HAVE LEFT IT OUT. && .PREV DISCUSSION... (ISSUED 330 AM EST FRI DEC 22 2006) DISCUSSION FOR ZONE AND GRID FORECASTS... MAIN FORECAST CONCERNS WILL THE RAIN TODAY AND ANY CHANCES OF PRECIPITATION AROUND CHRISTMAS. UPPER AIR AND WV SATELLITE SHOWS UPR LOW OVER ERN KS AND SE NE. WIND PROFILERS SHOW AN 85 KNOT SPEED MAX ROTATING NORTHEAST INTO THE MID MISSISSIPPI VALLEY AHEAD OF THE UPR LOW. THIS WAS CAUSING INCREASED UPR DIFFLUENCE ACROSS OUR AREA AND NUMEROUS SHOWERS WILL BE THE RULE TO AT LEAST MID MORNING. ADDITIONAL RAIN AMOUNTS FROM 1/2 INCH TO ONE INCH ARE POSSIBLE. A CHECK OF AREA SMALL CREEKS AND STREAMS SHOWS THAT MOST ARE JUST NOW RESPONDING TO THE DAYS RAIN. I WOULD EXPECT THAT MANY WILL APPROACH AND SOME MAY EXCEED FLOOD STAGE BY MIDDAY FRI IF ADDITIONAL WIDESPREAD ONE INCH RAINS OCCUR. AN URBAN AND SMALL STREAM FLOOD ADVISORY HAS BEEN ISSUED UNTIL MID MORNING OVER THE SOUTHERN HALF OF OUR FORECAST AREA. SURFACE ANALYSIS SHOWS A 1009 MB SURFACE LOW OVER NORTHEAST MISSOURI AND A COLD FRONT EXTENDING SOUTH FROM THIS LOW ACROSS EASTERN MISSOURI AND EASTERN ARKANSAS. THIS FRONT WILL MOVE EAST ACROSS OUR REGION THIS AFTERNOON. MODELS ALSO SHOW DRIER AIR SPREADING EAST ACROSS OUR REGION TODAY. MODELS ARE IN GENERAL AGREEMENT WITH DRIER AIR SPREADING EAST ACROSS OUR FORECAST AREA AFTER MID MORNING. RAIN SHOULD DECREASE INTO THE CHANCE CATEGORY MOST AREAS BY THIS AFTERNOON AND END BY TONIGHT. WITH CLOUDS AND PRECIP WILL GO CLOSER TO COOLER MET/FWC MOS TEMPERATURES TODAY. LONG TERM... THIS WEEKEND WILL USHER IN TRANQUIL CONDITIONS ACROSS OUR REGION AS THE DEPARTING SYSTEM CURRENTLY BRINGING THE WET WEATHER...MOVES TO THE NORTHEAST OF THE GREAT LAKES. FORECAST TEMPS THOUGH NOT QUITE AS WARM SHOULD REMAIN SLIGHTLY ABOVE AVERAGE BECAUSE OF THE MODIFIED AIRMASS MOVING IN FROM THE PLAINS. HIGH TEMPERATURES YESTERDAY WERE IN THE 40S OVER THE CENTRAL PLAINS. MODELS THIS WEEKEND INDICATE A SPLIT FLOW OVER THE WESTERN AND CENTRAL U.S. WITH AN UPPER LOW MOVING EAST INTO THE SOUTHERN PLAINS AND A S/W DIGGING INTO THE NORTHERN PLAINS BY LATE SUNDAY. THERE HAS BEEN CONSIDERABLE DISAGREEMENT FROM RUN TO RUN ON HOW QUICK THESE SYSTEMS PHASE AND WHETHER THE SOUTHERN SYSTEM WILL SPREAD PRECIPITATION NORTH INTO OUR REGION BY CHRISTMAS DAY. CURRENT GFS...WRF AND EWCF SHOW SOME PHASING BY CHRISTMAS AND THEY ALSO TAKE A SURFACE LOW WEST OF THE APPALACHIANS. EWCF AND WRF ARE A LITTLE SLOWER THAN GFS. WITH THE UNCERTAINTY BETWEEN RUNS AND NCEP PREFERRING TO NOT PHASING THESE SYSTEMS UNTIL THEY ARE EAST OF HERE...WILL KEEP PRECIP IN SLIGHT CHANCE FOR NOW. HOWEVER SE INDIANA MAY SEE A BETTER CHANCE FOR PRECIP. PUBLIC...JH && .IND WATCHES/WARNINGS/ADVISORIES... NONE. && AVIATION...JOHNSON
