Area forecast discussion, Sep 2, 2:45 PM CDT, 4 hours 27 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 245 PM CDT SAT SEP 2 2000 FRONT IS MOVING VERY SLOWLY ACROSS CENTRAL NEBRASKA. SHOULD GET SOME MODERATION AS FAR EAST AS OMA TO BIE TONIGHT ALTHOUGH STRONGEST WILL BE FURTHER WEST. CONTRAST IN TEMPS ACROSS THE AREA SHOULD BE GREATER TOMORROW. THERE APPEARS TO BE A SHORT WAVE MOVING NORTHEAST FROM NORTHEAST COLORADO WHICH WHICH IS ADDING TO THE CU DEVELOPMENT FROM GLD TO ONL. WHILE THERE MAY BE SOME CHANCE OF TSTMS WITH THIS MOST SHOULD LIFT NORTH NORTHEAST WEST IF THE CWA. THERE IS ANOTHER WAVE MOVING THROUGH NORTHEAST ARIZONA. THIS SHOULD BE HERE LATE TONIGHT AND THE FRONTAL BOUNDARY WILL HAVE MOVED EAST BEHIND THE FIRST WAVE. THIS MAKES IT PROBLEMATICAL TO TAKE OUT THE 20 PERCENT FOR TONIGHT...ESPECIALLY LATE TONIGHT. TOMORROW I WOULD ANTICIPATE THAT TEMPS WILL RANGE FROM AROUND 90 AT NLG TO AROUND 100 AT FNB. FOR NOW IT APPEARS THAT THE BEST CHANCE FOR FURTHER PRECIP IS MONDAY...WITH SOMEWHAT COOLER TEMPS DUE TO CLOUD COVER AS THE WARM FRONT STARTS NORTHEAST ACROSS THE AREA. .OMA...NONE POWERS
