** UPDATED TO ADD A FEW EXTRA COUNTIES TO HEAT ADVISORY **

...NRN EXTEND HEAT ADVISORY/SRN EXTENT OF TSRA CHCS 2 MAIN PRBLMS...

MOST SIGNIFICANT FEATURE THIS AM IS SFC TROF THAT WAS PUSHED SOUTH
TO NEAR KS BORDER BY NRN NB MCS OUTFLOW EARLY THIS AM. UEX 88D SHOWS
THIS BOUNDARY HAS STALLED W/ PORTION TO THE WEST OF HSI STARTING TO
EDGE BACK NORTH. THIS BOUNDARY WILL SEPERATE SULTRY CONDITIONS TO
ITS NORTH FROM THE BLAST FURNACE TO ITS SOUTH. HEAT ADVISORY IN GOOD
SHAPE ALONG/SOUTH OF BOUNDARY...BUT AREAS FROM HSI NORTH WILL HAVE
DIFFICULTY REACHING THE 105 DEG HI. WILL BASICALLY TAKE A LOOK AT 20Z
SFC OBS & DEDICE ON NRN EXTENT OF ADV TNGT INTO TOMR. 1ST THOUGHT IS
TO TRIM IT BACK TO SRN ROW OF NEB CNTYS INTO NC KS.

UAA/PROFILERS SHOW SRN EDGE OF THE WESTERLIES RUNNING ALONG NEB/SD
BORDER. MCS EARLY THIS MORNING WAS FIRED BY MONSOONAL WV WHICH WAS
VERY EVIDENT ON SAT PIX YSTY. NEXT SIGNIFICANT WV IS CURRENTLY MVG
THRU UT/ERN CO. THIS PROMISES TO FIRE CONVECTION OVER ERN WY/NE CO
AND NEB PNHDL LATE TODAY W/ ANOTHER MCS LIKELY CROSSING NRN NEB/SRN
SD LATE TNGT INTO SUN AM. WILL KEEP LOW POPS IN NRN AREAS TNGT. W/
UPPER RIDGE BASICALLY CENTERED NEAR THE OZARKS...SOME OF THIS ACTVY
MAY EVEN BRUSH WRN AREAS TNGT...BEFORE FOCUSING N.

THIS WILL LIKELY THROW ANOTHER BOUNDARY INTO THE AREA TOMR AM WHICH
WILL PENETRATE TO THE NEB/KS BORDER. BANKING ON THIS LOCATION...EXPCT
AREAS ALONG/SOUTH OF BOUNDARY TO REACH ADV CRITERION TOMR W/ NRN CWA
JUST FALLING SORT...BUT STILL REMAINING HOT/HUMID AS DWPTS POOL INTO
THE 70S AGAIN IN GENERALLY EASTERLY FLOW. BIG QUESTION UP NORTH WILL
BE DEGREE OF CONVECTIVE DEBRIS THAT HANGS AROUND DURING THE DAY. WL
RANGE TEMPS FROM 90S N TO NEAR 110 FAR SOUTH.

FROM MONDAY ON...GENERAL SOLUTION OF MEDIUM RANGE MDLS IS TO SHIFT
CENTER OF RIDGE SLIGHT WEST...WHILE AMPLIFYING PATTERN AS RIDGE GROWS
THRU ROCKIES/HI PLAINS AND DEEP UPPER TROF SETS UP SHOP IN ERN CAN/
NE US. THIS WILL PUT US IN BETTER NW FLOW...ALLOWING FOR MORE NORMAL
SUMMERTIME TEMPS IN THE 80S/90S AND A BETTER CHC FOR MCS ACTIVITY.
CURRENT EXTENDED HAS THIS WELL IN HAND...AND WILL CHANGE VERY LITTLE.
