SATELLITE ANALYSIS AND TRENDS...LONG LIVED QUASI-STATIONARY MCS
CONTINUES AFFECTING PRIMARILY SW NE THIS EVENING WITH THE HEAVIEST
RAIN MOSTLY CONCENTRATED FROM W PERKINS COUNTY SSW THROUGH W CHASE AND
INTO EXTREME NW DUNDY AND NE YUMA COUNTY.  THERE HAS BEEN SOME SLIGHT
WARMING TO THE OVERALL CLOUD SHIELD OF MCS BUT STILL THERE APPEARS TO
BE AN APPROXIMATE NNE/SSW AXIS ALONG THE COUNTIES MENTIONED ABOVE WHERE
NUMEROUS OVERSHOOTING TOPS WERE EVIDENT IN RECENT SATELLITE IMAGERY.
AUTOMATED SATELLITE ESTIMATES AROUND 6" WEST OF IML AND CONSIDERING THE
NOTED LOW BIAS IN THE AUTOMATED SATELLITE ESTIMATES BELIEVE THIS AMOUNT
IS LIKELY SUGGESTIVE OF TOTALS RANGING BETWEEN 6-8" OVER W PERKINS
AND W CHASE COUNTIES.  PRONOUNCED COLD POOL STILL QUITE EVIDENT IN
RECENT SURFACE OBSERVATIONS OVER SW NE AND VEERING LLJ CONTINUES TO BE
ISENTROPICALLY LIFTED OVER THIS BOUNDARY TO CONTINUE THE THREAT FOR
REGENERATING CONVECTION WITH DOWNSTREAM TRAINING.  RECENT PROFILER
DATA SUGGEST THAT NEARLY N/S LLJ AXIS ALIGNED FROM GLD INTO W THIRD
OF NE AND WITH PLENTY OF INSTABILITY UPSTREAM OF CURRENT CONVECTION
SEE NO REASON THE THREAT FOR HEAVY RAINFALL SHOULD NOT CONTINUE ON THE
SHORT TERM.  RAINFALL RATES OF OVER 2"/HR LIKELY OVER THE NEXT HOUR OR
SO WITH ADDITIONAL TOTALS OF 1-3" DURING THAT TIME FRAME.  CURRENT TRENDS
SUGGEST THAT THESE RATES AND TOTALS WILL BE FALLING OVER AREAS (W CHASE)
THAT ALREADY HAVE RECEIVED VERY HEAVY RAIN AND THIS WILL ONLY SERVE TO
EXACERBATE ONGOING SCENARIO.
