Area forecast discussion, Jan 8, 11:41 PM CST, 1 hour 1 minute before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
1141 PM CST FRI JAN 8 2016

.AVIATION...
THE LATEST HRRR BRINGS A FEW SHOWERS ACROSS KCLL/KUTS OVERNIGHT
BUT THE DEEPER CONVECTION IS WELL EAST OF AREA TAF SITES. LOW CIGS
AND AREAS OF FOG DEVELOPING IN THE WAKE OF THE CONVECTION WILL
CONTINUE TO HAMPER AVIATION INTERESTS OVERNIGHT. NOT MUCH
CONFIDENCE IN HOW THINGS EVENTUALLY PLAY OUT AS DRIER AIR TO THE
WEST SHOULD FILTER IN TO THE REGION OVERNIGHT. THERE COULD BE SOME
BRIEF CLEARING BEFORE WRAP AROUND CLOUDS BRING MVFR CIGS BACK TO
AREA TAF SITES FOR MUCH OF SATURDAY. WINDS WILL BE CONSIDERABLY
STRONGER ON SATURDAY AND ADDED A GUST GROUP. 43

&&

.PREV DISCUSSION... /ISSUED 923 PM CST FRI JAN 8 2016/

UPDATE...
QUICK FORECAST UPDATE TO DROP THE WESTERN TWO THIRDS OF THE
FORECAST AREA FROM SEVERE THUNDERSTORM WATCH 1 AS MAJORITY OF
CONVECTION HAS EXITED THE FORECAST AREA. HAVE ALSO ISSUED A
SHORT-FUSED DENSE FOG ADVISORY FOR THE WESTERN COUNTIES AS
VISIBILITIES HAVE DROPPED TO LESS THAN ONE MILE IN MANY LOCATIONS.
MAY POSSIBLY SEE DENSE FOG DEVELOP IN AND AROUND THE HOUSTON METRO
AS WELL... AND WILL CONTINUE TO MONITOR FOR POSSIBLE EASTWARD
EXPANSION OF THE ADVISORY. WINDS SHIFTING TO THE WEST/NORTHWEST
AHEAD OF AN APPROACHING COLD FRONT TONIGHT WILL HELP DISSIPATE
THE DENSE FOG THAT DEVELOPS... BUT GIVEN UNCERTAINTY ON TIMING THE
DENSE FOG ADVISORY MAY ALSO NEED TO BE EXTENDED IN TIME.

HUFFMAN

PREV DISCUSSION... /ISSUED 311 PM CST FRI JAN 8 2016/

DISCUSSION...
STARTING TO SEE AN INCREASE OF SHRA/TSRA ALONG AND NEAR THE UPPER
TX COAST THIS AFTN AS THE WARM FRONT (OR POSSIBLY A WEAK SFC LOW)
BEGINS TO DEVELOP/MOVE INLAND. RAIN CHANCES WILL CONTINUE TO INCREASE
THIS EVENING WITH THE APPROACH AND PASSAGE OF A STRONG UPPR LEVEL
DISTURBANCE FROM THE WEST. THERE IS A POSSIBILITY OF STRONG TO
SEVERE TSRA WITH THIS FEATURE GIVEN THE VERY STEEP LAPSE RATES AND
DYNAMIC JET STRUCTURE FOR THIS EVENING. HOWEVER..LIMITED DAYTIME
HEATING ALONG WITH A VERY DRY AIRMASS OVER SE TX ARE SOME OF THE
MAIN OBSTACLES TO OVERCOME FOR THESE STORMS TO DEVELOP. SPC'S DAY
1 OUTLOOK HAS MORE DETAILS.

THE PASSAGE OF THE STORM SYSTEM/UPPER TROF THIS EVENING WILL ALSO
DRAG A STRONG COLD FRONT ACROSS SE TX OVERNIGHT AND EARLY SAT
MORNING. COLDER/CLEARING FOR THE REST OF THE WEEKEND AS WINDS
ALOFT BECOME MORE NWLY WITH TIME. HOWEVER...AS IT HAS BEEN THE
CASE MORE OFTEN THAN NOT THIS SEASON...THE RIDGING WITH WILL BE
SHORT LIVED AS WE SEE THE RETURN OF THE SUBTROPICAL JET OVER THE
STATE WITH ANOTHER UPPER TROF DIGGING INTO NRN MEXICO. AND THEN BY
MON (WITH THE SFC HIGH MOVING OFF TO THE E/NE) WE SHOULD BEGIN TO
SEE THE RETURN OF SOME LOW POPS (COASTAL WATERS/SW PARTS OF THE
AREA)...BEFORE POPS SPREAD FURTHER INLAND (LATE WEDS/THUR) AS THE
UPPER TROF MOVES IN FROM THE WEST. 41

MARINE...
PATCHY AREAS OF DENSE SEA FOG WILL REMAIN A POSSIBILITY UNTIL 1-3AM
UNTIL A PREFRONTAL TROUGH PUSHES THRU THE WATERS. AHEAD OF THIS TROF...
WILL PROBABLY SEE SOME SCT SHOWERS/STORMS DEVELOP IN THE WATERS AS
UPPER LEVEL CONDITIONS BECOME MORE FAVORABLE. MAY SEE SOME ISOLATED
STRONGER CELLS CAPABLE OF PRODUCING WATERSPOUTS AND POSSIBLY GUSTY
WINDS. THREAT DIMINISHES AFTER MIDNIGHT ONCE WE SEE A WRLY WIND SHIFT.

COLD FRONT ITSELF WILL MOVE INTO THE AREA EARLY SAT MORNING. WINDS WILL
BECOME MORE NWRLY AND INCREASE TO CAUTION AND ADVSY CRITERIA. WINDS/SEAS
BEGIN DIMINISHING SUNDAY THEN GRADUALLY VEER TO THE NE/E INTO THE MIDWEEK
TIME PERIOD. 47
