DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0116 AM CST FRI FEB 26 2010
VALID 281200Z - 011200Z
AN UPPER-LEVEL LOW IS FORECAST TO MOVE ACROSS THE DESERT SOUTHWEST
SUNDAY AS A PRONOUNCED LOW-LEVEL JET STRENGTHENS IN THE SRN PLAINS.
THUNDERSTORMS WILL BE POSSIBLE SUNDAY AFTERNOON IN WEST TX ON THE
WRN EDGE OF THE LOW-LEVEL JET AND BENEATH THE CORE OF THE
UPPER-LEVEL TROUGH. ALTHOUGH MID-LEVEL LAPSE RATES WILL BE STEEP
ACROSS WEST TX...THE RELATIVELY DRY AIRMASS AND WEAK INSTABILITY
SHOULD LIMIT SEVERE POTENTIAL. AS THE UPPER-LEVEL TROUGH MOVES INTO
THE SRN PLAINS DURING THE OVERNIGHT PERIOD...THUNDERSTORM
DEVELOPMENT WILL BE POSSIBLE ALONG A WARM FRONT ACROSS THE LOWER TX
COASTAL PLAIN. HOWEVER...FORECAST SOUNDINGS LATE SUNDAY NIGHT SHOW A
WARM LAYER IN THE 850 TO 700 MB LAYER WITH WEAK INSTABILITY IN THE
MID-LEVELS. THIS SHOULD RESULT IN ELEVATED STORMS WITH WEAK UPDRAFTS
AND A SEVERE THREAT IS NOT ANTICIPATED.
..BROYLES.. 02/26/2010
