Area forecast discussion, Jul 28, 2:35 PM CDT, 3 hours 44 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 235 PM CDT FRI JUL 28 2000 PRECIPITATION WILL BE THE FCST CHALLENGE FOR THIS PACKAGE. TWO DIFFERENT SYSTEMS EXPECTED TO INFLUENCE THE CWA OVER THE NEXT 48 HRS. UPPER LOW OVR MI IS PROJECTED TO RETROGRADE SWWD DURG THE PERIOD. A SHORT WAVE OVER NW MO IS EXPECTED TO ROTATE AROUND THE UPPER LOW AND GENERATE A WAVE IN THE FRONTOGENETIC ZONE EXTENDING FROM NRN OK TO SRN IL OVERNIGHT... PASSING SOUTH OF THE CWA. THIS SHOULD CONTINUE THE THREAT OF PRECIP OVRNIGHT...INTO THE MORNING HRS OVR THE SRN CWA...AND OVER THE ERN CWA TMRW AS THE LOW TRACKS NEWD. SECOND THREAT COMES FROM THE UPPER LOW ITSELF. DIURNAL CONVECTION FIRING NICELY BENEATH THE UPPER LOW IN MI AND ACRS NRN IL/IN. WOULD XPCT SCATTERED TSTMS TO THREATEN CWA DURING THE AFTN HRS TMRW AND SUN AS THE UPPER LOW MOVES OVER THE CWA. MOST CONVECTION SHOULD DIE OFF UNDER THE UPPER LOW BY SUNSET...SO WILL LWR POPS ACCORDINGLY. I HAVE SOME CONCERN ABOUT THE ETA DEPICTION OF A LOW LVL MSTR CONVERGENCE ZONE ACRS THE CWA THIS EVENING...BUT WITH WINDS OF 5 TO 10 KTS...DONT XPCT THIS TO BE STRONG ENOUGH TO OVERCOME THE EVENING STABILIZATION. FARTHER OUT...UPPER LOW CONTINUES ITS SOUTHWESTERN JOURNEY THRU 1ST PART OF NEXT WEEK. THIS SHUD CONTINUE THE THREAT OF DIURNAL CONVECTION THRU TUE. WILL TRY TO BRING THE PRECIP THREAT TO AN END BY WED AS THE UPPER LOW IS PROJECTED TO MOVE NEAR...TULSA? TEMPERATURES NOT TOO CLEAR CUT EITHER. ETA 2M TEMPS WERE DOING WELL THROUGH THE MORN HRS TODAY...BUT SEEMED TO NOT TAKE THE DIURNAL CLOUDS INTO EFFECT. AFTN TEMPS HAVE BEEN RUNNING A LITTLE BELOW THE ETA 2M NUMBERS. ETA TEMPS LOOK A LITTLE BETTER TMRW AND SUNDAY...SO WILL USE THEM WITH MINOR ADJUSTMENTS. ...PRELIMINARY CCF FOR COORDINATION ONLY...
