Area forecast discussion 
National Weather Service Norman OK 
1150 PM CDT Thursday may 23 2013 


Aviation...06z taf issuance... 
there remains a chance for isolated showers and thunderstorms 
overnight...but given lack of confidence in coverage and 
timing...decided to leave mention out of the tafs at this time. 
Currently...VFR ceilings and visibilities will continue to 
persist. With increasing clouds through the morning...some 
locations may flirt with MVFR at times. Winds will remain breezy 
out of the east through sunrise before shifting out of the 
southeast. Winds will remain breezy through the afternoon...with 
some gusts to near 20 kts. Isolated showers and thunderstorms 
remain possible Friday afternoon...but once again...given lack of 
confidence in location and timing...decided not to mention it for 
this taf issuance.

Update... 
updated probability of precipitation 


Discussion... 
very tricky forecast this evening...with a myriad of boundaries 
and sufficient moisture...surface dew points are in the 60s across OK 
and the texoma region...isolated thunderstorms remain possible 
across the region this evening and overnight. Currently...a across 
central and western OK and western North Texas...the weather remains relatively 
quiet...however a weak updraft developed over Comanche County near 
Lawton...but continues to weaken. 


Regional radar mosaic shows redevelopment behind the initial West 
Texas line of convection. With surface dew points struggling in 
the low 50s across the lub County Warning Area...these updrafts will continue to 
struggle but may make there way slowly eastward into western North Texas... 
and remain sub-severe. 


With any storms that form overnight across the region...the best 
chances will be across southwestern OK and western North Texas...but a slight chance 
will exist across the rest of the area through sunrise. Although 
the majority of storms will likely stay below severe 
criteria...the strongest storms will be possible of winds in 
excess of 60 miles per hour and hail to the size of quarters.
