AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 225 PM CDT TUE APR 11 2006 .DISCUSSION... MAIN CONCERN IS POTENTIAL FOR CONVECTION THROUGH THE EVENING. THE ATTENTION WILL TURN TOWARD TEMPERATURES AFTER THAT. SYSTEM DURING THE WEEKEND STILL SEEMS STRONG ENOUGH TO WARRANT CHANCE POPS. SURFACE ANALYSIS AT 19Z SHOWED A COLD FRONT EXTENDING SOUTHWARD FROM MINNESOTA INTO WESTERN KANSAS. A 999 MB LOW PRESSURE CENTER WAS NOTED ALONG THE FRONT IN NERN NE. SURFACE DEWPOINTS SOUTH OF THE LOW HAD DROPPED INTO THE 35-45 F RANGE. ELSEWHERE...DEWPOINTS WERE MAINLY 45-50. VISIBLE SATELLITE IMAGES SHOWED CLOUDS TRYING TO DEVELOP FROM ALBION TOWARD YANKTON AND WAYNE. LATEST WATER VAPOR LOOP DEPICTED A STRONG SHORTWAVE TROUGH MOVING NORTHEAST THROUGH THE REGION. RUC INITIALIZATION AT 18Z INDICATED 12 HOUR 500 MB HEIGHT FALLS IN EXCESS OF 80 METERS IN NWRN KS. LOW LEVEL MOISTURE IS LIMITED...BUT IT APPEARS THAT THERE WILL BE ENOUGH DYNAMICS FOR SCATTERED THUNDERSTORMS LATE THIS AFTERNOON AND EVENING. SEVERE POTENTIAL IS THERE...BUT NOT OVERLY HIGH. WILL END CHANCE OF PCPN BY 06Z TONIGHT...EXCEPT OVER THE SWRN CORNER OF IOWA...WHERE WILL LINGER SOME LOW POPS UNTIL 09Z. WILL KEEP THINGS DRY FROM WEDNESDAY THROUGH THURSDAY. WEDNESDAY STILL LOOKS LIKE A GOOD DAY...WITH MUCH LIGHTER WINDS. 850 MB TEMPERATURES ARE EXPECTED TO BE 13-15 DEGREES C. THE 12Z NAM/ETA IS WARMER...AND IS PREFERRED OVER THE SLIGHTLY COOLER GFS. HIGHS SHOULD REACH 75-80. PREVIOUS SHIFT BOOSTED HIGHS THURSDAY...AND THAT WAS NOT CHANGED. LOOKS LIKE HIGHS IN THE LOWER AND MID 80S... AND COULD END UP JUST A BIT WARMER IF WE GET FULL MIXING. BY THURSDAY NIGHT...WRN IA COULD SEE SOME ISOLATED THUNDERSTORMS... IF THE ATMOSPHERE IS NOT CAPPED. BETTER CHANCE IS STILL EXPECTED OVER THE WEEKEND. THE ECMWF IS NOT AS STRONG AS THE GFS WITH THE SYSTEM. ELEVATED STORMS COULD DEVELOP LATE FRIDAY NIGHT NORTH OF THE SURFACE WARM FRONT. COLD FRONT WILL PUSH EASTWARD DURING THE DAY SATURDAY...BUT IT PROBABLY WILL NOT REACH OUR AREA UNTIL SATURDAY NIGHT. THAT IS WHEN WE HAVE THE HIGHEST CHANCE. WE MIGHT SEE SOME LINGERING SHOWERS ON SUNDAY...IF THE SYSTEM SLOWS DOWN. LEFT SOME LOW POPS IN FOR NOW IN OUR NRN AND ERN ZONES. HIGHS SATURDAY AFTERNOON SHOULD REACH THE MID 70S NORTH TO LOWER 80S SOUTH...BUT SUNDAY WILL BE 5-10 DEGREES COOLER. EARLY NEXT WEEK ...AT LEAST MONDAY AND TUESDAY...SHOULD BE DRY. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...NONE. IA...NONE. && MILLER
