AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
350 AM CDT SUN MAR 18 2012

.SHORT TERM /TODAY THROUGH MONDAY/...
WELL ADVERTISE MID TO UPPER LEVEL TROUGH DIGGING FURIOUSLY OVER
SOUTHERN CALIFORNIA THIS MORNING. THIS TROUGH SHOULD CONTINUE TO DIG
SOUTH WITH A 160+ MPH JET ON THE WEST SIDE BEFORE TURNING EASTWARD
TONIGHT. BROAD SUBTROPICAL FLOW EAST OF THE MAIN TROUGH CONTINUES TO
SPREAD A THICK CIRRUS ACROSS MUCH OF NORTHERN AND EASTERN MEXICO AND
SOUTH TEXAS. SOME CONVECTION IS OCCURRING IN THE WEAK DIVERGENT FLOW
OVER NUEVO LEON BUT HAS BEEN WEAKENING AS IT APPROACHES TAMAULIPAS.
QUESTION FOR TODAY AND TONIGHT WILL ANY ADDITIONAL CONVECTIVE
ACTIVITY FORMING OVER MEXICO REACH OUR CWA. LIMITED LOW AND MID
LEVEL MOISTURE AND STRONG CAP WILL LIKELY BE THE CONTROLLING FACTORS
IN LIMITING CONVECTION IN OUR REGION THE NEXT 24 TO 36 HOURS.
HOWEVER CAN NOT RULE OUT A FEW SHOWERS SURVIVING THE HOSTEL
ENVIRONMENT AND WORKING THEIR WAY INTO AT THE WESTERN COUNTIES. RAIN
CHANCES WILL BE LOW BUT MEASURABLE RAIN IS NOT ANTICIPATED.

ANOTHER DAY OF BREEZY CONDITIONS BEFORE STRONGER WINDS DEVELOP
MONDAY AS THE LOW PRESSURE TROUGH EDGES CLOSER. GFS MOST BULLISH
WITH THE LOW LEVEL JET STRENGTHEN TO 40 KNOTS TONIGHT AND SHOWING
LITTLE WEAKENING MONDAY BEFORE PEAKING OVER 50S KNOTS MONDAY NIGHT
A WIND ADVISORY IS NOT OUT OF THE QUESTION FOR MONDAY BUT THE
THICKER CLOUDS COVER MAY LIMIT THE MIXING OF THE STRONGEST WINDS TO
THE SURFACE. COULD SEE STRONG GUSTS OVER 30MPH WELL INTO MONDAY
EVENING.

THE THICK CLOUDS HAD A NUMBER ON TEMPERATURES YESTERDAY AFTERNOON
KEEPING HIGHS IN CHECK. LOOKING FOR SIMILAR CONDITIONS TODAY AND
MONDAY. THE COOLER OR NOT AS HOT MAV GUIDANCE WILL BE THE MODEL OF
CHOICE.  OVERNIGHT LOWS TONIGHT WILL LIKELY BE WARM WITH A STEADY
BREEZE AND THE CLOUDS COVER LIMITING MUCH OF ANY HEAT LOST. /59/

.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
MOST OF THE WEATHER IMPACTS FOR THE LONG TERM PORTION OF THE
FORECAST STILL APPEAR TO BE ASSOCIATED WITH THE PASSAGE OF A FRONT
IN THE MONDAY NIGHT/TUESDAY MORNING TIME FRAME.

THE GOOD NEWS...THE LATEST MEDIUM RANGE MODELS APPEAR TO BE IN A
LITTLE BETTER AGREEMENT EARLY THIS MORNING WITH REGARD TO THE
SYNOPTIC SCALE EVOLUTION/TIMING OF THE STORM SYSTEM.  THE BAD
NEWS...THAT DOES NOT MAKE THE FORECAST ANY EASIER.

A LONGWAVE TROUGH AXIS IS EXPECTED TO BE LOCATED JUST EAST OF THE
FOUR CORNERS REGION MONDAY NIGHT.  AN APPROACHING 250MB JET
STREAK...ROUNDING THE BASE OF THE UPPER TROUGH...WILL LIKELY AID IN
SOME SURFACE CYCLOGENESIS ALONG THE FRONT OVER THE MEXICAN STATES OF
COAHILA OR NUEVO LEON MONDAY NIGHT.  LARGE SCALE ASCENT AHEAD OF THE
STORM SYSTEM WILL LIKELY RESULT IN SOME CONVECTIVE DEVELOPMENT ALONG
THE FRONT.

THE APPROACH OF THE UPPER TROUGH WILL LIKELY RESULT IN SOME COOLING
IN THE MID-LEVELS OF THE ATMOSPHERE OVERNIGHT...AS THE SURFACE LOW
AND COLD FRONT MOVE ACROSS OUR AREA.  THIS MAY WEAKEN THE STRONG
CAPPING INVERSION JUST ENOUGH TO ALLOW A LITTLE BETTER COVERAGE OF
SHOWERS AND STORMS TO BE SEEN /ESPECIALLY/ OVER OUR NORTHERN TIER OF
COUNTIES.

THUNDERSTORM INTENSITY REMAINS IN QUESTION EARLY THIS SUNDAY
MORNING.  KINEMATIC FIELDS APPEAR TO BE INDICATIVE OF STRONG/SEVERE
STORMS...WITH BOUNDARY LAYER WIND SPEEDS BETWEEN 40 AND 50 KNOTS
ANTICIPATED.  THE LOW-LEVEL SHEAR PARAMETERS APPEAR TO BE IN PLACE
ACROSS THE REGION AS WELL...AS THE MAGNITUDE OF SURFACE TO 1KM BULK
SHEAR INCREASES REGION WIDE BETWEEN 7PM MONDAY AND 1AM TUESDAY.  THE
INSTABILITY APPEARS TO BE THERE AS WELL.  LIFTED INDICES OVER THE
UPPER VALLEY MAY RANGE BETWEEN -5 AND -7 DEGREES CELSIUS BY
MIDNIGHT...WITH SURFACE-BASED CAPE VALUES POSSIBLY IN EXCESS OF 3000
JOULES/KG SHOWN ON MODEL FORECAST SOUNDINGS.

HOWEVER...THE SAME MODEL FORECAST SOUNDINGS CONTINUE TO SHOW A
STRONG CAPPING INVERSION /3-5 DEGREES CELSIUS/ OVER THE NORTHERN
TIER OF COUNTIES AND RISING LCL HEIGHTS.  IN ADDITION...THE GREATEST
UPPER-LEVEL DIFFLUENCE APPEARS TO OCCUR NORTH OF OUR FORECAST AREA.
THIS LEADS ME TO BELIEVE THAT BOTH THE CONVECTIVE COVERAGE AND
INTENSITY WILL LIKELY REMAIN RATHER LIMITED IN OUR AREA AS THE STORM
SYSTEM MOVES THROUGH.  BECAUSE OF THIS UNCERTAINTY...THE POSSIBILITY
OF STRONG /NOT SEVERE/ STORMS WILL CONTINUE TO BE MENTIONED IN THIS
MORNING/S HAZARDOUS WEATHER OUTLOOK.  PRECIPITATION PROBABILITIES
WILL REMAIN GREATEST OVER OUR NORTHERN COUNTIES WITH THIS FORECAST
PACKAGE.

IN GENERAL...I EXPECT A RATHER NARROW LINE OF CONVECTION /A
SO-CALLED SQUEEGEE LINE/ TO MOVE ACROSS THE FORECAST AREA ALONG THE
COLD FRONT.  THUNDERSTORMS/FRONT WILL LIKELY MOVE EAST OF THE US-281
CORRIDOR SOMETIME BETWEEN 2 AND 5 AM...THEN OFFSHORE BETWEEN 7 AND 9
AM.  DRIER AIR WILL MOVE INTO THE REGION BEHIND THE FRONT...BRINGING
AN END TO ANY CONVECTION BY TUESDAY AFTERNOON.  OF COURSE...THIS FAR
OUT...THE TIMING IS SUBJECT TO CHANGE.

A CUTOFF LOW IS FORECAST TO DEVELOP OVER THE SOUTHERN PLAINS BY
TUESDAY NIGHT...AS THE LONGWAVE TROUGH BECOMES SEPARATED
/MORE-OR-LESS/ FROM THE NORTHERN STREAM ENERGY.  AS A RESULT...THE
UPPER LEVEL SYSTEM WILL LIKELY EJECT INTO THE MISSISSIPPI VALLEY
THURSDAY.  SURFACE HIGH PRESSURE/UPPER-LEVEL RIDGING SHOULD BUILD
INTO OUR AREA FROM THE WEST IN WAKE OF THE STORM SYSTEM...AND
PROVIDE DRY WEATHER CONDITIONS INTO NEXT WEEKEND.

THE TERM COLD FRONT MAY BE SOMEWHAT OF A MISNOMER THIS TIME OF
YEAR.  SLIGHTLY ABOVE NORMAL HIGHS FOR MIDDLE AND LATE MARCH /LOWER
AND MIDDLE 80S/ WILL LIKELY DROP TO NEAR NORMAL /AROUND 80/ AFTER
