DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1256 AM CDT SUN APR 15 2007
VALID 161200Z - 171200Z
..NO SVR TSTM AREAS FORECAST...
..SYNOPSIS...
UPPER LOW INITIALLY OVER AZ IS FORECAST TO MOVE EWD ACROSS THE SWRN
U.S. THIS PERIOD. IN RESPONSE...SURFACE PRESSURE FALLS ACROSS THE
CENTRAL AND SRN HIGH PLAINS WILL TURN LOW-LEVEL FLOW SELY ACROSS TX
AND INTO ERN NM. HOWEVER...WITH NLY/NELY FLOW OVER MOST OF THE GULF
AT THE START OF THE PERIOD IN THE WAKE OF PRIOR COLD FRONTAL
PASSAGE...DEGREE OF MOISTURE RETURN SHOULD REMAIN QUITE LIMITED
THROUGH THE END OF THE PERIOD.
..PARTS OF THE SWRN CONUS...
MEAGER BOUNDARY LAYER MOISTURE ADVECTING NWWD INTO THE HIGH PLAINS
WILL RESULT IN ONLY WEAK DESTABILIZATION AT BEST ACROSS THE HIGH
PLAINS. SCATTERED WEAK/HIGH-ELEVATION STORMS WILL BE POSSIBLE
ACROSS PARTS OF UT/CO/AZ/NM...AS WILL A FEW HIGH-BASED STORMS OVER
THE HIGH PLAINS OF ERN NM/FAR W TX. INSTABILITY SHOULD REMAIN
INSUFFICIENT...HOWEVER...FOR ANY APPRECIABLE SEVERE THREAT.
OVERNIGHT...INCREASING LOW-LEVEL JET OVER THE SRN HIGH PLAINS MAY
SUPPORT SCATTERED/ELEVATED STORMS...BUT AGAIN -- LIMITED INSTABILITY
SUGGESTS LITTLE SEVERE POTENTIAL THROUGH THE END OF THE PERIOD.
