NWS Lincoln, IL wrote its last area forecast discussion before the first event at Jun 13, 12:40 PM CST, 4 hours 20 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 140 PM CDT FRI JUN 13 2003 LATEST SURFACE ANALYSIS HAD WEAK LOW PRESSURE CENTERED OVER EAST CENTRAL ILLINOIS...WITH A WARM FRONT EXTENDING INTO INDIANA AND OHIO AND A COLD FRONT EXTENDING INTO SOUTHEAST MISSOURI. MAIN CONCERNS THIS PACKAGE REVOLVE AROUND DISPOSITION OF PRECIPITATION WITH DEPARTING SYSTEM AND THE THREAT OF ADDITIONAL PRECIPITATION OVER THE NEXT FEW DAYS. 12Z MODELS IN GOOD OVERALL AGREEMENT. THE ETA SEEMS TO HAVE INITIALIZED BETTER WITH THE WEAK SHORT WAVE OVER MONTANA AT THE MOMENT AND SLIDES IT MORE AGGRESSIVELY INTO THE REGION SUNDAY INTO MONDAY THAN THE OTHER MODELS. HAVE FOLLOWED THE SOLUTION OF THE ETA MORE CLOSELY AS A RESULT. GUIDANCE TEMPERATURES CLOSE AND REASONABLE IN DEPICTING SEASONABLE AIRMASS OVERHEAD...SO WILL NOT STRAY TOO FAR. TONIGHT...THIS WILL MARK THE TRANSITION FROM THE ACTIVE WEATHER OF THE PAST SEVERAL DAYS TO A QUIETER PATTERN. WEAKENING UPPER/SURFACE LOW WILL GRADUALLY TRACK EAST ACROSS THE OHIO VALLEY...ALLOWING UPPER RIDGING AND AN ASSOCIATED SURFACE HIGH TO BUILD IN FROM THE PLAINS. PLAN ON HAVING PRECIP END FROM WEST TO EAST DURING THE PERIOD... FOLLOWED BY A LITTLE CLEARING LATE. DO NOT EXPECT SKIES TO CLEAR OUT TOO RAPIDLY AS SUBSIDENCE/DRYING BEHIND THE SYSTEM IS NOT TOO STRONG AND LIGHT WINDS AND ABUNDANT LOW LEVEL MOISTURE FROM RECENT RAINS SHOULD ALLOW FOR FOG/STRATUS DEVELOPMENT. SATURDAY THROUGH MONDAY...NOT A WHOLE LOT TO HANG YOUR HAT ON AS FAR AS WEATHER FEATURES TO BE CONCERNED ABOUT DURING THE PERIOD. UPPER RIDGING/SURFACE HIGH BECOME BETTER ESTABLISHED OVER THE REGION WITH TIME. ENOUGH LOW LEVEL MOISTURE REMAINS TO SUPPORT DIURNAL CU DAILY (ESPECIALLY SATURDAY). PLAN ON MAINTAINING CURRENT DRY FORECAST THROUGH THE PERIOD...THOUGH I DO HAVE A FEW CONCERNS. THERE IS NOT MUCH DRYING TO SPEAK OF BEHIND DEPARTING SYSTEM...WITH MODEL SOUNDINGS SUGGESTING CAPE VALUES APPROACHING 1500 J/KG ON SATURDAY. THERE SHOULD NOT BE A FOCUSING MECHANISM PRESENT TO INITIATE CONVECTION...THOUGH THAT HAS NOT STOPPED A FEW STORMS FROM DEVELOPING ACROSS IOWA TODAY. MY OTHER MAIN CONCERN IS WITH A WEAK UPPER WAVE THAT IS FORECAST TO DROP INTO THE REGION FOR SUNDAY/MONDAY TIME FRAME (ESPECIALLY PER THE ETA). DIURNAL CAPE VALUES PROGGED TO EXCEED 1000 J/KG EACH DAY AND THIS WAVE MAY PROVIDE ENOUGH FORCING TO POP SOME STORMS (DESPITE CURRENT LACK OF A SURFACE REFLECTION IN THE MODELS). TUESDAY THROUGH FRIDAY...EXTENDED MODELS AND THEIR ENSEMBLES IN GOOD OVERALL AGREEMENT IN DEPICTING THE MAIN WEATHER FEATURES EXPECTED TO IMPACT CENTRAL ILLINOIS DURING THE PERIOD. HOWEVER...AS CAN BE EXPECTED IN A WEAK SUMMER FLOW PATTERN...THERE ARE SOME DISAGREEMENTS ON THE FINER DETAILS. SUPPER/SURFACE RIDGING EXPECTED TO BREAK DOWN/TRANSLATE EAST OF REGION AS TROFFING WORKS ITS WAY INTO CENTRAL NORTH AMERICA. MODELS HAVE TRENDED SLIGHTLY QUICKER BRINGING THIS TROFFING TOWARD ILLINOIS...SO WILL INTRODUCE A CHANCE OF SHOWERS AND THUNDERSTORMS STARTING LATE TUESDAY NIGHT. THE THREAT FOR SHOWERS/STORMS SHOULD PERSIST INTO FRIDAY...WITH THE MODELS SUGGESTING PERSISTENT TROFFING IN THE UPPER FLOW AND A FRONTAL BOUNDARY IN THE VICINITY OF CENTRAL ILLINOIS THROUGH THE PERIOD. TEMPERATURES SHOULD REMAIN NEAR SEASONAL NORMALS. .ILX...NONE. BAK
