EVENT...LINEAR MCS
.
SATELLITE ANALYSIS AND TRENDS...NORTHERN PORTION OF THE LINEAR MCS
CONTINUES TO TRACK EASTWARD AND CONTINUES TO POSE A FF THREAT.  IR LOOP
SHOWS TWO LARGER CLUSTERS OF COLD TOPS ONE OVER CENTRAL IA AND THE
OTHER OVER N MO...EVEN THOUGH TOPS ARE BEGINNING TO WARM AND ONLY ONE
SIGNIFICANT OVERSHOOTING TOP CAN BE SEEN OVER JASPER COUNTY, IA... FF
GUIDANCE CAN BE EASILY ECLIPSED BY ESTIMATED TOTAL AMOUNTS ASSOCIATED
WITH LINE.  PWS ARE STILL 1.7" AND TOPS ARE COLDER THAN -60C...SO MANUAL
RATES OF 1.5-2"/HR ARE THE NORM...BUT THE ORIENTATION TO THE LLJ HAS
BECOME MORE PARALLEL TO THE N-S LINE AT 850 ACROSS THE DISCUSSED AREA
SO MORE ISENTROPIC LIFT IS OCCURRING OVER MORE E-W ORIENTED PORTIONS
OF THE THE OUTFLOW BOUNDARY ACROSS C MO AND CONSEQUENTLY  A LARGER
PRECIPITATION SHIELD HAS DEVELOPED WEST OF THE LINE AND THE LEADING EDGE
OF THE SQUALL LINE AND ASSOCIATED CLOUD TOPS HAVE WARMED BUT EXPANDED.
THIS WILL LEAD TO A LONGER DURATION OF MODERATE RAINFALL WITH 1HR TOTALS
ON THE LEADING EDGE OF .5-1.0"...BUT A FEW HOURS MORE OF .5"/HR RATES IN
THE SHIELD PRECIP...FOR 3HR TOTALS OVER 2-3"...CLEARLY EXCEEDING FFG.
OVER THE NEXT 3-6HRS...REDUCED SFC AND LLJ CONVERGENCE WILL LEAD TO
OVERALL WEAKENING OF LINE AND LOWER FF THREAT.
