LOW CLOUDS WERE HAVING A DIFFICULT TIME BREAKING OUT ACROSS PARTS

CONTINUE THIS EVENING AND MOST OF THE OVERNIGHT HOURS. LOW CLOUDS

EASTERN HALF OF THE CWA. THE STRONG COLD FRONT DIVING SWD ACROSS
NW TX THIS AFTERNOON WILL ARRIVE IN THE NWRN CWA IN THE EARLY
MORNING HOURS AND APPROACH THE I35 CORRIDOR BY DAYBREAK WITH A
LINE OF SCATTERED SHOWERS/ISOLATED STORMS ALONG THE FRONT. THE
COLD FRONT QUICKLY PUSHES EAST OF THE CWA BY EARLY AFTERNOON AND
THEREFORE THE SEVERE RISK IS REDUCED FOR THIS AREA AS THE COOLER
DRIER AIRMASS QUICKLY BUILDS IN BEHIND THE FRONT. WILL STILL
MENTION A FEW STRONG STORMS OVER THE FAR EASTERN COUNTIES IN THE
