DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0748 PM CDT TUE APR 13 2010

VALID 140100Z - 141200Z

...NO SVR TSTM AREAS FORECAST...

...PARTS OF WRN AND CENTRAL NEB SSWWD INTO NERN NM AND VICINITY...
CONVECTION CONTINUES TO DIMINISH IN INTENSITY ACROSS THE
DAKOTAS...BUT A FAIRLY ORGANIZED LINE OF STORMS CONTINUES FROM N
CENTRAL NEB SSWWD INTO ERN CO. THESE STORMS ARE ONGOING ALONG A
COLD FRONT WHICH CONTINUES MOVING EWD OUT OF THE HIGH PLAINS. MORE
ISOLATED STORMS ALSO EXTEND AS FAR S AS NERN NM...AHEAD OF THE COLD
FRONT ALONG AN ERN NM DRYLINE.

AIRMASS AHEAD OF THE ONGOING STORMS REMAINS MODESTLY UNSTABLE...BUT
WITH THE ONSET OF DIURNAL BOUNDARY -LAYER COOLING...EXPECT EXISTING
STORMS TO BEGIN A SLOW DECREASE IN INTENSITY OVER THE NEXT COUPLE OF
HOURS.

UNTIL THEN...STRENGTH OF THE FLOW FIELD ALOFT SUGGESTS THE POTENTIAL
FOR A LOCALLY STRONGER/SEVERE STORMS -- CAPABLE OF PRODUCING
DAMAGING WINDS AND MARGINAL HAIL.
