DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0653 PM CST SUN MAR 07 2010
VALID 080100Z - 081200Z
...NO SVR TSTM AREAS FORECAST...
...SERN NM INTO W TX...
CONVECTION PERSISTS ACROSS THE SWRN QUARTER OF THE U.S. AHEAD OF A
STRONG UPPER LOW NOW CENTERED INVOF THE LOWER CO VALLEY OF SERN
CA/SWRN AZ. STRONGEST CELLS ATTM CONTINUE EVOLVING ACROSS ERN NM
AND ADJACENT PORTIONS OF TX...WHERE DEWPOINTS AOB THE LOW 50S
COMBINED WITH DAYTIME HEATING HAVE YIELDED MODEST INSTABILITY -- AOB
500 J/KG MIXED-LAYER CAPE.
AS THE UPPER LOW SHIFTS SLOWLY EWD...MODEST INSTABILITY WILL REMAIN
THE PRIMARY LIMITING FACTOR FOR A MORE SUBSTANTIAL SEVERE THREAT. A
FEW SURFACE-BASED STORMS -- AIDED BY FAVORABLY VEERING/INCREASING
FLOW WITH HEIGHT -- MAY PRODUCE MARGINAL HAIL OR LOCALLY-GUSTY WINDS
OVER THE NEXT COUPLE OF HOURS. OVERNIGHT...STORMS SHOULD INCREASE
ACROSS ERN NM AND EXPAND EWD ACROSS W TX...BUT A COOLING BOUNDARY
LAYER AFTER SUNSET SUGGESTS THAT STORMS WILL BECOME ELEVATED.
LIMITED INSTABILITY ALOFT...THOUGH...COULD SUPPORT A
LOW-END/MARGINAL HAIL THREAT THROUGH THE END OF THE PERIOD.
