BASED ON SATELLITE IMAGERY...WEATHER OBSERVATIONS...RADAR...
AND METEOROLOGICAL ANALYSIS.

BASED ON 1200 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
1545 UTC.

..ITCZ...
INTERTROPICAL CONVERGENCE ZONE...4N77W 7N85W 5N112W 7N125W
5N140W. SCATTERED MODERATE 60 NM EITHER SIDE OF AXIS FROM 101W
TO 106W.

DISCUSSION...
W OF 100W...
DEEP LAYER LONGWAVE TROUGH COVERED THE AREA N OF 25N BETWEEN
100W AND 120W. SEVERAL SHORTWAVES/VORT MAXIMA WERE ROTATING
THROUGH THE TROUGH. THE FIRST NEAR EL PASO TEXAS WAS MOVING
ENE 15-20 KT. THE SECOND WAS DROPPING SWD 20 KT DOWN THE
BACKSIDE OF THE TROUGH OVER EXTREME SOUTHERN CALIFORNIA. A
SHEAR AXIS EXTENDED FROM THE BASE OF THE TROUGH NEAR 25N110W
WSWWD ACROSS BAJA CALIFORNIA TO 22N132W TO A CYCLONIC
CIRCULATION CENTER NEAR 26N140W. THIS SHEAR AXIS WAS
UNDERCUTTING A HIGHLY AMPLIFIED RIDGE N OF THE AREA. MODERATE

ALONG 27N/28N. THE JET IS ADVECTING AN ABUNDANT AMOUNT OF
TROPICAL MOISTURE ACROSS E PAC BASIN INTO CENTRAL MEXICO AND
TEXAS. TRANSVERSE BANDING WITHIN THE CLOUD FIELD SUGGESTED
MODERATE OR GREATER CLEAR AIR TURBULENCE. SURFACE RIDGE WITH
AXIS FROM 32N132W TO 18N108W.
