AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
307 PM CDT MON MAY 13 2013

.DISCUSSION...
SOUTHEAST TEXAS WILL SEE INCREASING CLOUDS AND WARMER TEMPERATURES THIS
WEEK UNDER A LIGHT TO MODERATE ONSHORE FLOW. RAIN CHANCES COME BACK
INTO THE FORECAST TUESDAY NIGHT THROUGH WEDNESDAY EVENING AS THE CUTOFF
LOW OVER MEXICO OPENS UP AND KICKS OUT ACROSS THE STATE AND HELPS TO
GENERATE SCATTERED SHOWERS AND THUNDERSTORMS. UPPER RIDGING IS STILL
EXPECTED TO BUILD BACK OVERHEAD AS THE MIDWEEK STORM SYSTEM MOVES OFF
TO THE EAST DURING THE SECOND HALF OF THE WEEK...AND THIS WILL BRING
INCREASING TEMPERATURES AND HUMIDITY TO ALL OF SOUTHEAST TEXAS UNDER
THE PERSISTENT ONSHORE WINDS. MODELS STILL HAVE THE RIDGE FLATTENING
OVER THE WEEKEND AND INTO THE EARLY PART OF NEXT WEEK IN RESPONSE TO
THE NEXT STORM SYSTEM MOVING EASTWARD ACROSS THE PLAINS. THIS COULD
EVENTUALLY ALLOW A WEAK FRONTAL BOUNDARY TO SAG INTO OUR AREA AND
POSSIBLY GIVE US OUR NEXT RAIN CHANCES.  42

.MARINE...
HIGH PRESSURE RIDGING POSITIONING ITSELF OFF ACROSS THE SOUTHEASTERN
U.S. THROUGH MID-WEEK WILL MAINTAIN A LONG DURATION SOUTHEASTERLY
FLOW. A NORTHEASTERN-PASSING UPPER LEVEL DISTURBANCE WEDNESDAY WILL
INCREASE THE PROBABILITY OF SCATTERED RAIN SHOWERS AND PERIODS OF
THUNDERSTORM ACTIVITY. 31
