SHORT TERM /TODAY THROUGH MONDAY/...500MB RIDGE ACROSS DEEP SOUTH
TEXAS AND NORTHEAST MEXICO WILL CONTINUE TO PROVIDE SUBSIDENCE
ACROSS THE RIO GRANDE VALLEY TODAY. THE UPPER LEVEL RIDGE WILL
SHIFT EASTWARD TONIGHT INTO MONDAY AS A 500MB TROUGH ACROSS THE
NORTHWEST UNITED STATES MOVES EASTWARD. WINDS WILL INCREASE
TONIGHT INTO MONDAY AS THE PRESSURE GRADIENT INCREASES ACROSS THE
LOWER TEXAS COAST. THE INCREASE IN WINDS TONIGHT SHOULD INHIBIT
WIDESPREAD FOG DEVELOPMENT LATE TONIGHT INTO MONDAY MORNING BUT
WILL MENTION SOME PATCHY FOG SINCE MOISTURE WILL CONTINUE TO
INCREASE AT THE SURFACE.

ALOFT FOR THE FIRST HALF OF THE WEEK. THIS WILL HELP TO HALT THE
PROGRESS OF THE INITIAL COLD FRONT MOVING THROUGH TEXAS ON
WEDNESDAY...PULLING UP SHORT WELL TO THE NORTH. DRY AIR REMAINS IN
PLACE ACROSS SOUTH TEXAS...CONTINUING TO BRING TEMPERATURES AROUND
90 AND NO RAIN CHANCES. AN H5 RIDGE ACROSS SOUTHERN CALIFORNIA
PROGRESSES INLAND FOR THE LATTER HALF OF THE WEEK...TURNING WINDS
ALOFT FROM THE NORTHWEST. THIS WILL HELP NUDGE WHATS LEFT OF THE
FRONT FURTHER SOUTH INTO SOUTH TEXAS ON FRIDAY...BUT SFC FOCUS
REMAINS VERY BROAD. WITHOUT A SHARPER FOCUS AND CONTINUED LIMITED
MOISTURE...RAIN CHANCES WILL BE MINIMAL...WITH BEST CHANCES LATE
THURSDAY INTO FRIDAY MORNING. DO NOT EXPECT MORE THAN A SLIGHT

COVER.

NEAR 6 KNOTS AT BUOY020 EARLY THIS MORNING. LIGHT SOUTHEAST WINDS

PRESSURE ACROSS THE NORTHERN GULF COAST. WINDS WILL INCREASE TONIGHT
AS LOW PRESSURE ACROSS THE CENTRAL UNITED STATES ALLOWS THE PRESSURE
GRADIENT TO INCREASE ACROSS THE WESTERN GULF OF MEXICO. MODERATE
SOUTHEAST WINDS WILL PREVAIL ACROSS THE LOWER TEXAS COAST TONIGHT
INTO MONDAY AS A RESULT.

TUESDAY THROUGH THURSDAY...SOUTHEAST WINDS WILL REMAIN BREEZY
TUESDAY WITH SLOWLY RELAXING GRADIENT BTWN FRONTAL LOW TO THE
NORTH AND GENERAL RIDGE ACROSS THE GULF. WITH THE FRONT
