[Ounce]

The front has cleared Austin. Temps went from 75 to 55.

[srainhoutx]

Just had a wind gust to 45MPH here in NW Harris County. Looks like the squall line will arrive around 6 to 7 AM. Except 20F temperature drop with the Pacific front.

It also appears to be a very changeable weather week with another storm system arriving mid week bringing in a piece of much colder air for the end of the work week. Also the potent Bering Sea cyclone has been analyzed at 924mb tying Extra Tropical Storm Nuri last November in the Bering Sea.

http://www.spc.noaa.gov/products/md/md2011.html


MESOSCALE DISCUSSION 2011
NWS STORM PREDICTION CENTER NORMAN OK
0717 AM CST SUN DEC 13 2015

AREAS AFFECTED...UPPER TX COAST

CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY

VALID 131317Z - 131445Z

PROBABILITY OF WATCH ISSUANCE...20 PERCENT

SUMMARY...A LOCALIZED WIND DAMAGE/WEAK TORNADO RISK MAY DEVELOP NEAR
GALVESTON BAY OVER THE NEXT 1-2 HOURS. LIMITED SPATIAL
COVERAGE/MAGNITUDE OF THE THREAT WILL LIKELY PRECLUDE A WATCH
ISSUANCE.

DISCUSSION...LATEST TRENDS IN KHGX RADAR IMAGERY SHOW A FEW WEAK
ROTATIONAL COUPLETS S OF GALVESTON ISLAND MOVING NNEWD AND ARE
EXTRAPOLATED TO REACH THE COAST OVER THE NEXT 1-2 HOURS. WHILE THIS
CONVECTION IS OCCURRING LARGELY IN THE ABSENCE OF DETECTED
LIGHTNING...THE VERY STRONG AND VEERING LOW-LEVEL WIND PROFILE
COUPLED WITH SUFFICIENT BUOYANCY IS SUPPORTING UPDRAFT ROTATION.
THE MAIN THREATS WITH ANY SHALLOW SUPERCELL WOULD BE A LOCALIZED
WIND DAMAGE AND WEAK/BRIEF TORNADO THREAT BEFORE THE COLD FRONT
UNDERCUTS THE STORM ACTIVITY LATER THIS MORNING.
