DAY1SVR: Day 1 Convective Outlook

ACUS01 KWNS 181617
SWODY1
SPC AC 181616

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1116 AM CDT SUN OCT 18 2009

VALID 181630Z - 191200Z

...NO SVR TSTM AREAS FORECAST...

THE COMBINATION OF STEEP LAPSE RATES WITH THE VERY WARM CONDITIONS
FOR MID OCTOBER ALONG WITH THE MEAGER BUT SUFFICIENT MOISTURE...
SHOULD LEAD TO PRIMARILY DIURNALLY DRIVEN WEAK CONVECTION OVER BOTH
THE NORTHERN INTERMOUNTAIN REGION AND HIGHER TERRAIN OF ERN AZ/WRN
NM.

THE APPROACHING S/WV TROUGH FROM OFF THE PAC COAST AND ACCOMPANYING
MID LEVEL COOLING AND ASCENT WILL LIKELY CONTINUE THE THREAT OF
WEAK CONVECTION AFTER DARK NRN INTERMOUNTAIN REGION.
