AREAS AFFECTED...NORTH-CENTRAL OREGON
CONCERNING...SEVERE THUNDERSTORM WATCH 248...
VALID 290153Z - 290330Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 248
CONTINUES.
SUMMARY...WHILE ISOLATED OCCURRENCES OF MARGINALLY SEVERE HAIL
AND/OR DAMAGING WINDS REMAIN POSSIBLE, AN OVERALL DECREASE IN STORM
INTENSITY IS EXPECTED THROUGH 03 UTC. REMAINING VALID PORTIONS OF
THE WATCH WILL LIKELY BE ALLOWED TO EXPIRE AT THAT TIME.
DISCUSSION...A CLUSTER OF STRONG THUNDERSTORMS IS ONGOING AS OF
01:45 UTC ACROSS A SMALL PART OF NORTH-CENTRAL OR, NAMELY MORROW AND
GILLIAM COUNTIES. LATEST OBJECTIVE ANALYSIS SUGGESTS THAT THE LOCAL
ENVIRONMENT REMAINS AT LEAST MARGINALLY UNSTABLE WITH INCREASING
CONVECTIVE INHIBITION. AS SUCH, THE EXPECTATION IS FOR A GRADUAL
DECREASE IN STORM INTENSITY THROUGH 03 UTC. PRIOR TO THE TIME,
CONSTRUCTIVE STORM INTERACTIONS COULD LEAD TO PERIODS OF
INTENSIFICATION, WITH AN ASSOCIATED RISK FOR MARGINALLY SEVERE HAIL
AND/OR WIND GUSTS.
SHOULD CURRENT STORM TRENDS CONTINUE, THE REMAINING VALID PORTION OF
SEVERE THUNDERSTORM WATCH 248 WILL LIKELY BE ALLOWED TO EXPIRE AT 03
UTC.
