SOUTH CENTRAL NEBRASKA/NORTH CENTRAL KANSAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE HASTINGS NE 250 PM CDT SAT JUL 7 2001 ** 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.
