EVENT...LINEAR MCS
.
SATELLITE ANALYSIS AND TRENDS...THE BASE OF THE TROF HAS SHARPED QUITE A
BIT OVER THE LAST 6HR ACROSS THE HIGH PLAINS AS STRONGER 115 KT JET IS
HELPING THE SURGE OF THE COLD FRONT SOUTH ACROSS WESTERN AND CENTRAL
TX...AS THE LINEAR MCS -WEDGE- CONTINUES TO RAPIDLY EXPAND SWWARD.
INCREASING SWLY FLOW AHEAD OF THE FRONT IS LEADING TO VERY IMPRESSIVE
MOISTURE TRANSPORT THAT IS FEEDING THE MCS WITH 40-50KT 850 FLOW SEEN IN
THE VWP NETWORK ACROSS TX INTO S AR.  PERSISTENT VERY COLD TOPS FROM -55
TO -65C HAVE LEAD AUTOMATED SATELLITE ESTIMATION TO LEAVE A LARGE SWATH
OF 1" ESTIMATES WITH A FEW LOCAL MAXIMA OF 2 TO 2.5" WERE SOME OF THE
NEW DEVELOPMENT IN NE TX BEGAN TO MERGE INTO THE MAIN LINE ACROSS S AR.
A 3" 3HR ESTIMATE ENDING AT 11Z WAS LOCATED OVER CENTRAL MCCURTAIN COUNTY
OK WITH A 2.3" MAXIMA OVER DELTA COUNTY.  FURTHER NORTH INTO CENTRAL
AR...THE TOPS ARE NOT AS COLD BUT HAVE BEEN MORE EXPANSIVE AS THE MCS
SHIELD OF PRECIP HAS EXPANDED NORTHWARD BEHIND THE FRONT... LEADING
TO MODERATE RAINS THAT HAVE ALSO BE ESTIMATED OVER 2" ACROSS YELL INTO
PERRY COUNTIES.  THIS SHIELD AREA WILL CONTINUE TO EXPAND OVER THE NEXT
FEW HOURS AS THE STRONGER CELLS AT THE LEADING EDGE OF THE LINE BEGIN TO
WANE...AS SEEN BE RECENT IR TRENDS SHOW A SIGNIFICANT WARMING OCCURRING
ACROSS MUCH OF THE LINE ACROSS AR AND NE TX.
