Weekly Severe Weather Discussion

Severe Weather Discussion for January 5 – 11, 2009.
Valid: 01/04/2009.

Highlights:

– Freezing rain is likely tomorrow morning across parts of North
Texas into southern Oklahoma. There may be light freezing rain or
drizzle in central Oklahoma, but impacts are expected to remain limited.

– Temperatures will be in the 30s on Monday and 50s Tuesday warming
to the upper 50s and 60s Wednesday – Friday. A cold front is expected
late Friday with temperatures in the mid 40s to mid 50s Saturday and
Sunday.

Probabilities:

Severe Thunderstorms in Oklahoma: < 5%
Storm Chase: < 5%
Winter Precip: 10%

Discussion:

Main action this forecast period will be on Monday as a southern
stream shortwave trof approaches from the southwest U.S. and
eventually phases with a northern stream system. Once this system
gets by there will be no activity until Friday when a northern stream
shortwave trof pushes a cold front through the region. 12z ECMWF
shows a small southern stream shortwave trof moving towards the area
but moisture appears limited ATTM. So, beyond Monday, going low POPs
the rest of the week.
