Area forecast discussion, Nov 1, 2:54 PM CST, 6 hours 35 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TOPEKA KS 254 PM CST SUN NOV 1 1998 ...MAIN FORECAST PROBLEM IS HEAVY RAIN/FLOODING THREAT OVERNIGHT... 18Z SURFACE MAP HAD LOW PRESSURE OVER CENTRAL OKLAHOMA WITH 15 TO 20 KNOT NORTHEAST FLOW OVER NORTHEAST KANSAS. RADAR LOOPS SHOW FIRST BAND OF HEAVY RAIN HAS SHIFTED NORTHWEST INTO NORTH CENTRAL KANSAS ...WITH A SECOND AREA OF HEAVY RAIN DEVELOPING OVER SOUTHEAST KANSAS. WATER VAPOR LOOPS PLACED UPPER LOW OVER WESTERN OKLAHOMA AT 20Z...MOVING EAST-NORTHEAST. GENERALLY FOLLOWED THE AVN FOR THIS FORECAST AS IT IS A GOOD COMPROMISE BETWEEN THE FASTER NGM AND SLOWER ETA. 850-700 MB AND 700-300 MB DIVERGENCE OF Q-VECTORS IMPLY STRONG UPWARD MOTION WILL SPREAD OVER NORTHEAST KANSAS OVERNIGHT AS THE UPPER LOW MOVES INTO SOUTHEAST KANSAS OVERNIGHT. HEAVY RAIN SHOULD CONTINUE OVERNIGHT AS VERY MOIST (213% OF NORMAL) IS TAPPED BY DEEP UPWARD MOTION. SHOULD SEE ANOTHER ONE TO TWO INCHES FALL BY 12Z MONDAY. THIS WILL ONLY AGGRAVATE CURRENT FLOODING PROBLEMS. WILL CONTINUE FLOOD WATCH ACROSS NORTHEAST AND EAST CENTRAL KANSAS OVERNIGHT. UPPER LOW SHEARS OUT AS IT RUNS INTO UPPER LEVEL RIDGE OVER MINNESOTA. UPPER FORCING SHOULD GRADUALLY WEAKEN DURING THE DAY AS LOW SHEARS OUT. THUS THINK THE PRIMARY HEAVY RAIN THREAT WILL BE TONIGHT. ENOUGH VERTICAL MOTION WILL REMAIN TO PRODUCE WIDESPREAD LIGHT PRECIPITATION OVER NORTHEAST KANSAS THROUGH MONDAY NIGHT. LIGHT PRECIPITATION SHOULD GRADUALLY END TUESDAY MORNING AS DIVERGENCE OF Q-VECTORS SHOW LIFT MOVING NORTHEAST OUT OF THE AREA. RELATIVE HUMIDITY FORECASTS SHOW PLENTY OF LOW LEVEL MOISTURE REMAINING OVER THE AREA THROUGH TUESDAY...SO EXPECT CLOUDS TO LINGER. AVN/FAN GUIDANCE LOOKS TOO COOL AND TRENDED TEMPERATURES TOWARD WARMER NGM/FWC NUMBERS AS CLOUDS AND PRECIPITATION SHOULD LIMIT TEMPERATURES SWINGS. .TOP...FLOOD WATCH TONIGHT SOUTHEAST OF AN ABILENE TO MARYSVILLE LINE. 58
