UPDATED AVIATION SECTION

.DISCUSSION...

TONIGHT THROUGH SUNDAY...THE REGION WILL REMAIN UNDERNEATH
MOIST...SOUTHWEST FLOW ALOFT WHILE TO THE WEST...A LOW PRESSURE TROF
WILL MOVE TOWARDS THE WEST COAST. STRONG WINDS ALOFT WILL
CONTINUE TO BRING STRONG AND GUSTY WINDS TO THE LOWER LEVELS
ACROSS THE CWA BUT THESE WINDS WILL WEAKEN QUICKLY DURING THE
EVENING. THE UPPER LEVEL LOW PRESSURE TROF WILL APPROACH THE WEST
COAST BY SATURDAY AFTERNOON AND SURFACE LOW PRESSURE WILL DEVELOP
ACROSS THE ZONES UNDERNEATH THE SOUTHWEST FLOW AHEAD OF THE TROF.
TEMPS WILL WARM WELL ABOVE NORMALS...AND MANY NEAR RECORD HIGHS
ARE EXPECTED ACROSS THE ZONES. WITH THE HEATING...THE AIRMASS WILL
BECOME SLIGHTLY UNSTABLE BY AFTERNOON AND THE CONVECTIVE OUTLOOK
PUTS MOST OF THE ZONES UNDERNEATH GENERAL THUNDERSTORMS. CAPE WILL
BE STRONGEST ACROSS CENTRAL AND SOUTHWEST ZONES. THE TROF WILL
BEGIN TO SPLIT SATURDAY NIGHT WITH THE STRONGEST DYNAMICS MOVING
WELL SOUTH OVER THE SOUTHWEST US...FLOW THROUGH THE TROF OVER THE
ZONES WILL BE RATHER WEAK. WINDS AT LOWER LEVELS SHOULD SHIFT AS A
COLD FRONT PASSES BEFORE OR AROUND MIDNIGHT ACROSS MOST OF THE
CWA...SOUTHERLY LOW LEVEL FLOW COULD CONTINUE ACROSS THE NORTHEAST
ZONES PAST MIDNIGHT. THE AIRMASS WILL COOL BEHIND THE COLD FRONT
WITH COOLER TEMPS ON SUNDAY. FLOW THROUGH THE TROF WILL REMAIN

WITH AN UPPER TROF EXITING TO THE EAST SUNDAY NIGHT AND HIGH
PRESSURE BUILDING OVER THE AREA ON MONDAY AND PERSISTING THROUGH
TUESDAY. DRY CONDITIONS WITH GENERALLY LIGHT WINDS WILL START THE
PERIOD. THE UPPER RIDGE AXIS MOVES TO THE NORTHERN PLAINS ON
WEDNESDAY AS AN UPPER TROF DIGS ALONG THE WEST COAST. INCREASING
SOUTHWEST FLOW ALOFT WILL BRING MOISTURE AND PRECIPITATION TO THE
WESTERN AND SOUTHWEST MOUNTAINS. THE UPPER TROF MOVES INLAND ON
THURSDAY WITH THE MAIN ENERGY CONTINUING TO DIG SOUTH. STRONG
SOUTHWEST FLOW ALOFT AND A COLD FRONT MOVING ACROSS THE AREA WILL
ALLOW FOR RAIN SHOWERS OVER THE PLAINS AND SNOW IN THE MOUNTAINS TO
INCREASE IN AREAL COVERAGE. MODELS BEGIN TO EXHIBIT TIMING
DIFFERENCES WITH THEIR SOLUTIONS FOR FRIDAY BUT AGREE ON CONTINUED
SHOWERS FOR THE AREA. TEMPERATURES WILL BE ABOVE SEASONAL AVERAGES
TO START THE PERIOD BUT DROP TO NEAR SEASONAL AVERAGES ON THURSDAY.
