&&

.DISCUSSION...
STRONG WINDS AND MUCH COOLER TEMPERATURES WILL BE THE BIG WEATHER
STORY THE NEXT COUPLE OF DAYS AS A VERY POWERFUL STORM SYSTEM
AFFECTS THE SOUTHWEST UNITED STATES. THE UPPER LOW IS CURRENTLY
CENTERED NEAR THE WASHINGTON/OREGON COAST...AND IS MOVING SOUTH
PARTIALLY IN RESPONSE TO PRONOUNCED UPSTREAM RIDGING. DARKENING
SIGNATURE TO THE SOUTH OF THE UPPER LOW IS INDICATIVE OF A
PRONOUNCED STRATOSPHERIC INTRUSION AND SYSTEM INTENSIFICATION.
NUMERICAL GUIDANCE IN EXCELLENT AGREEMENT THAT AS THIS SYSTEM MOVES
SOUTH ALONG THE COAST NEXT 12-18 HRS...IT WILL INTENSIFY AND EVOLVE
INTO A VIGOROUS NEGATIVELY-TILTED TROUGH OVER CENTRAL- SOUTHERN
CALIFORNIA BY 00Z WEDNESDAY (5 PM LOCAL TIME). ASSOCIATED STRONG

AS THE SURFACE COLD FRONT APPROACHES FROM THE WEST. FRONT EXPECTED
TO PASS EAST ACROSS SOUTH CENTRAL ARIZONA BY AROUND 12Z
WEDNESDAY...WITH WINDY CONDITIONS FROM THE WEST DURING THE DAY ON
WEDNESDAY AS PRONOUNCED COLD ADVECTION OCCURS. WIND ADVISORY HAS
ALREADY BEEN POSTED FOR SE CALIFORNIA AND WEST-CENTRAL ARIZONA...AND
THIS ADVISORY MAY NEED TO BE EXPANDED TO COVER PORTIONS OF SOUTH
CENTRAL ARIZONA AS WELL. ALSO...IT IS POSSIBLE HIGH WIND WARNING
CRITERIA MAY BE MET FOR SEVERAL HOURS OVER THE WIND PRONE REGIONS OF
FAR SOUTHEAST CALIFORNIA THIS EVENING.

SHARP THERMAL DISCONTINUITY EXISTS WITH THIS FRONTAL ZONE...WITH
FORECAST SOUNDINGS INDICATING MAX TEMPS WEDNESDAY WILL BE 15-20

NOTICEABLY COLDER MIN TEMPS WEDNESDAY NIGHT...ESPECIALLY OVER
SOUTH-CENTRAL ARIZONA WHERE LOW TEMPS THURSDAY MORNING COULD BE
10-15 DEGREES BELOW NORMAL...BUT WIND WILL BE DECREASING OVERNIGHT.
COOL CONDITIONS WILL PERSIST ON THURSDAY AS UPPER LOW SPINS NEAR THE
FOUR CORNERS REGION...THOUGH SOME MODIFICATION OF THE AIR MASS WILL
OCCUR MAINLY OVER FAR SE CALIFORNIA.

IN EXTENDED...STRONG UPPER LOW MOVES SLOWLY EAST AND REACHES THE
TEXAS PANHANDLE REGION BY 12Z SATURDAY. AS SUCH...FORECAST AREA WILL
REMAIN UNDER CYCLONIC FLOW ALOFT THROUGH AT LEAST FRIDAY. TEMPS WILL
MODERATE ON FRIDAY...BUT STILL BE BELOW NORMAL FOR MID-APRIL. MODELS
FORECAST UPPER RIDGE TO SLOWLY MOVE EAST AND BECOME THE DOMINANT
WEATHER FEATURE OVER THE WESTERN UNITED STATES THIS WEEKEND INTO
EARLY NEXT WEEK. EXPECT ADDITIONAL WARMING AS THIS OCCURS...WITH
MODEL SOUNDINGS INDICATING THAT TEMPS WILL RETURN TO NEAR NORMAL
LEVELS BY SATURDAY...AND ABOVE NORMAL LEVELS BY SUNDAY. MAX TEMPS
