.DISCUSSION...
WATER VAPOR IMAGERY SHOWING STRONG CYCLONE OVER GULF OF AK WITH
ASSOC TROF MOVING ONSHORE ACROSS PAC NW/BRITISH COLUMBIA ALONG WITH
125KT+ JET. AS A RESULT U/A ANALYSIS SHOWING AMPLIFIED RIDGE ACROSS
WESTERN STATES YESTERDAY...HAS BROADENED AND MOVED OVER CENTRAL
CONUS AT 00Z THIS EVENING. THIS RIDGE WILL BE FURTHER FLATTENED
TODAY AS PAC NW ENERGY MOVES INTO CANDIAN PRAIRIES AND JET MOVES
INTO NORTHERN ROCKIES. THIS WILL MEAN ONE MORE VERY WARM DAY AGAIN
ACROSS WESTERN AND NORTH CENTRAL NEBRASKA...WITH STEEP LLVL LAPSE
RATES LEADING TO WELL MIXED PBL TAPPING INTO THE THERMAL RIDGE.
GUIDANCE GOING FOR RECORD/NEAR RECORD TEMPS AT BOTH VTN AND LBF. BC
GUIDANCE SEEMED TO BE RUNNING TOO LOW YESTERDAY AND 2M TEMPS WERE
ALSO ON THE LOW SIDE SO WILL LEAN TOWARD THE MET GUIDANCE...WITH
LOWER 80S FAR SOUTWHEST...TO MID AND UPPER 70S ELSEWHERE. EXPECT
SOME GUSTY WINDS AS WELL THIS AFTERNOON WITH THE STEEPER LAPSE
RATES...AND THIS COMBINED WITH RECORD TEMPS AND DRY CONDITIONS
SHOULD LEAD TO NEAR CRITICAL FIRE WEATHER CONDITIONS ACROSS
PANHANDLE AND SANDHILLS THIS AFTERNOON. COOL FRONT WILL PUSH THROUGH
CWA OVERNIGHT AS A NEARLY ZONAL PATTERN SETS UP ACROSS THE NORTHERN
CONUS. FAST PROGRESSIVE PATTERN CONTINUES TO LEAN TOWARD WARMER THAN
NORMAL AND MAINLY DRY CONDITIONS THROUGH THE FORECAST PERIOD.
TEMPERATURES WILL MODERATE INTO THE 60S THORUGH THE WEEKEND BEHIND
FRONT...THEN DROPPING INTO THE MID 50S TO LOWER 60S FOR THE FIRST OF
NEXT WEEK BEHIND YET ANOTHER FROPA. SMALL PRECIPITATION CHANCES
STILL POSSIBLE BEHIND THIS FRONT SUNDAY NIGHT INTO MONDAY MORNING
BUT MOISTURE STILL SEEMS TO BE THE BIG FACTOR WITH NAM PROFILES
SHOWING DRY ENOUGH LOW LAYERS TO KEEP SPRINKLES AND VIRGA A GOOD
POSSIBILITY. GFS SEEMS TO BE OUTLIER TO MUCH OF OTHER GUIDANCE WITH
STRENGTH OF TROF MOVING ACROSS NORTHERN PLAINS AND A SLOWER
FROPA...SO DECIDED TO OMIT THIS POSSIBILITY AT THIS TIME. NO BIG
CHANGES NEEDED FOR THIS PACKAGE.
