Area forecast discussion, Apr 18, 1:25 PM CST, 4 hours 35 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PADUCAH KY 225 PM CDT SUN APR 18 2004 .DISCUSSION... ALL MODELS AGREE THAT PCPN CHANCES SHOULD REMAIN PRIMARILY NORTH AND WEST OF THE PAH FA THRU TONIGHT. THIS IS NOT TO SAY LIGHT SHOWER OR SPRINKLE ACTIVITY WONT BE FLIRTING WITH THE NWRN PERIPHERY BY MORNING...BUT FOR NOW...WL FOLLOW THE LAST 3 MODEL RUN TRENDS AND LEAVE IT OUT. BEGINNING 12Z MON...MODELS HAVE BEEN REASONABLY CONSISTENT LAST SEVERAL DAYS ON OVERALL THEME OF FORECAST...WHICH IS TO YIELD A DAILY PCPN CHC THRU THE WEEK AS ACTIVE DEEPENED/MOIST SW FLOW ALOFT INTERACTS W/MEANDERING BOUNDARY ACROSS FA. WHERE MODELS HAVE OFFERED THEIR DIFFERENCES HAVE BEEN IN EXACT AREAL PLACEMENT AND TO A LESSER EXTENT THE TIMING OF THE BOUNDARY WITH RESPECT TO ITS AFFECT ON PAH FA. THE LAST RUN SHIFTED IT A BIT FUTHER NORTH AND RESULTED IN SMALLER POPS FOR OUR SRN/ERN REACHES ON OCCASION...HOWEVER...THIS RUN THE BOUNDARY COMES BACK A TAD AND MOS GUIDANCE YIELDS AT LEAST CHC CAT POPS THRU THE PERIOD. WL PLAY A MIDDLE GROUND APPROACH WITH THIS SINCE THE MODELS ARE OBVIOUSLY STILL TRYING TO SYNCHRONIZE...IE WL REMAIN IN CHC CAT BUT GENERALLY LESS THAN MOS ON POPS. MODELS ARE ALSO HAVING TROUBLE LOCKING IN ON HOW THIS WEEKS PCPN CHC AND MORE ACTIVE UPPER PATTERN IS GONNA END. YDAY ENSEMBLES SWEPT THE FRONT THRU QUICKLY WHILE MRF LAGGED IT WAY BEHIND...LINGERING POPS THRU SAT-SAT NIGHT. NOW MRF IS QUICKER BUT IS CLOSING OFF AN UPPER LOW...AND SURFACE BOUNDARY IS SOUTH AND EAST. AFTER COLLABORATION W/ILS AND LSX (THANKS)...DECIDED TO DROP THUNDER THREAT FRI NIGHT...AND PCPN THREAT BY SAT...WITH MOST OF ACTIVITY HOPEFULLY SOUTH AND EAST BY THEN. THAT IS A CAUTIOUS APPROACH CONSIDERING LOW MODEL CONFIDENCE. WARM MOS IS THE WAY TO GO NEAR TERM FOR SURE. LATER IN FORECAST IT IS MORE QUESTIONABLE BUT WE STAY ON OR JUST ABOVE MOS SINCE IT IS WANTING TO REALLY PULL IN THE COOLER AIR AND WE WANT TO APPROACH THAT LATTER FORECAST SGFPERIOD CAUTIOUSLY TOO. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...NONE. IN...NONE. KY...NONE. MO...NONE. && DH
