.AVIATION...
EXPECTING VFR CONDITIONS THROUGH LATE EVENING AS WINDS TURN ONSHORE
AND BEGIN TO STRENGTHEN. LOW CLOUDS WILL BEGIN TO DEVELOP WITH THE
INCREASING MOISTURE...AND EXPECT TO SEE SOME MVFR CEILING DEVELOPMENT
TOWARD MORNING AS WINDS STAY IN A 5 TO 10 KNOT RANGE. MVFR CEILINGS
ANTICIPATED FOR MUCH OF THE DAY TOMORROW ALONG WITH STRENGTHENING
SOUTH WINDS (15 TO 20 KNOTS AND GUSTY LATE MORNING THROUGH AFTERNOON).

.PREV DISCUSSION... /ISSUED 1006 AM CST THU FEB 19 2015/

UPDATE...
MORNING WATER VAPOR IMAGERY CONTINUES TO SHOW A SUBTLE SHORTWAVE
TRANSLATING ACROSS WEST CENTRAL TEXAS...PUSHING A CIRRUS DECK
AHEAD OF IT OVER SOUTHEAST TEXAS AS IT MOVES EAST. A DIFFUSE
FRONTAL BOUNDARY /REALLY MORE OF A WIND SHIFT/ BISECTED THE
FORECAST AREA THIS MORNING ROUGHLY FROM NEAR COLLEGE STATION
SOUTHEAST TOWARDS GALVESTON. EASTERLY WINDS THIS MORNING BEHIND
THE BOUNDARY WILL VEER TO THE SOUTH AS A SURFACE TROUGH OVER WEST
TEXAS DEEPENS. SOUTHERLY WINDS AND MOSTLY CLEAR TO PARTLY CLOUDY
SKIES WILL ALLOW AFTERNOON TEMPERATURES TO CLIMB GENERALLY INTO
THE 60S. CURRENT FORECAST HANDLES THIS WELL AND ONLY MINOR
ADJUSTMENTS MADE TO HOURLY TEMPERATURE...DEW POINT...AND SKY GRIDS
BASED ON OBSERVATIONS.

HUFFMAN

PREV DISCUSSION... /ISSUED 413 AM CST THU FEB 19 2015/

DISCUSSION...

WEAK HIGH PRESSURE AT THE SURFACE THIS MORNING HAS ALLOWED FOR
CALM WINDS AND WITH CLEAR SKIES...TEMPS CONTINUE TO DROP INTO THE
UPPER 30S. SFC ANALYSIS HAS A WEAK BACK DOOR COLD FRONT ALONG A
WACO/HUNTSVILLE/LAKE CHARLES LA LINE. FRONT WILL BE NOTHING MORE
THAN A WIND SHIFT TODAY AS THE BOUNDARY STALLS ACROSS THE AREA.
SFC RIDGE WILL BE MOVING EAST TODAY AND LEE TROUGH WILL DEVELOP IN
THE HIGH PLAINS. THIS SHOULD INCREASE THE PRESSURE GRADIENT WITH
STRONG SE WINDS DEVELOPING IN THE AFTERNOON AND INTO THE
OVERNIGHT. WATER VAPOR IMAGERY SHOWS A SHORT WAVE TROUGH OVER NEW
MEX WHICH WILL REACH THE AREA BY EVENING/OVERNIGHT. THE SHORT WAVE
WILL LIKELY INCREASE CLOUD COVER BUT DO NOT EXPECT ANY PRECIP.

BROAD TROUGHING AND HUDSON BAY LOW WILL PERSIST INTO THE WEEKEND.
THIS WILL KEEP UPPER LEVEL RIDGE OVER THE PAC COAST AS ANOTHER LOW
DEVELOPS OVER THE GREAT BASIN BY SUNDAY. NORTHERLY FLOW ALOFT
THROUGH THE PLAINS ON THE BACK SIDE OF THE HUDSON BAY LOW WILL
SUPPORT ANOTHER STRONG COLD FRONT AT THE SURFACE. A 1048MB HIGH
PRESSURE SHOULD BUILD OVER THE N PLAINS ON SUNDAY WITH THE COLD
FRONT PUSHING THROUGH THE AREA. AHEAD OF THE FRONT FRI/SAT EXPECT
WARM ADVECTION PATTERN TO SUPPORT SHOWER ACTIVITY AS MOISTURE
INCREASES. PRECIP WATER VALUES INCREASE TO AROUND 1.3 TO 1.5
INCHES LATE SATURDAY INTO SUNDAY. MODEL SOUNDINGS SHOW SOME
CAPPING BUT MAY BE ENOUGH INSTABILITY TO SUPPORT A FEW ISO
THUNDERSTORMS DURING THIS TIME. RAIN CHANCES OF 30 TO 50 PERCENT
LOOK ON TRACK FOR THE AREA.

FRONT APPEARS TO TAKE ITS TIME MOVING INTO THE GULF SUNDAY INTO
MONDAY. A SHORT WAVE TROUGH EMBEDDED IN SOUTHERN BRANCH OF JET
STREAM MOVES ACROSS MONDAY MORNING INCREASING RAIN CHANCES
BRIEFLY. MODEL SOUNDINGS FOR KCLL AND KLFK SUPPORT RAIN WITH A
PRONOUNCED WARM NOSE ABOVE A SHALLOW SUB FREEZING LAYER. SEE NO
NEED TO MENTION ANY FROZEN PRECIP AT THIS TIME SINCE T/TD PROFILES
DO NOT SUPPORT IT. BUT IF THE AIRMASS IS COLDER THAN
FORECAST...THEN THERE WILL BE SOMETHING TO MONITOR. OVERALL SET UP
FOR ANY PRECIP TYPE OTHER THAN RAIN LOOKS MARGINAL AT BEST.

HIGH PRESSURE BUILDS OVER THE AREA AGAIN FOR MID WEEK. THE GFS
AND ECMWF ARE NOT IN HORRIBLE AGREEMENT FOR THE EXTENDED. LOOKS
LIKE ANOTHER UPPER LOW WILL APPROACH TX FROM THE DESERT SW WHICH
COULD INCREASE RAIN CHANCES FOR THE END OF NEXT WEEK.

39

MARINE...

ONSHORE FLOW WILL REDEVELOP TODAY AS HIGH PRESSURE MOVES
OFF TO THE EAST. AS THE PRESSURE GRADIENT TIGHTENS AND SEAS BUILD
EXPECT CAUTION STATEMENTS BY THIS EVENING WITH ADVISORY FLAGS
POSSIBLE FOR THE OFFSHORE WATERS. A STRONG COLD FRONT WILL PUSH OFF
THE COAST AROUND MIDDAY ON SUNDAY WITH STRONG NORTH TO NORTHEAST
WINDS PERSISTING INTO EARLY NEXT WEEK. 38
