Priority 3 Saturday.
 
Area:
East of I-35
 
Time:
Noon to 5pm
 
Main Threats:
Hail to Golfball size, thunderstorm wind to 75mph, a few tornadoes
 
Summary:
Warm, humid and unstable air is in place in North TX this morning.  A dry line will move in from the west early this afternoon.  As the dry line moves east, storms will develop quickly.  The exact development point and time is still uncertain, depending on the strength of the capping inversion in the lower levels of the atmosphere.  The risk of severe storms will increase dramatically east of the metroplex, with a high risk of severe storms and tornadoes in NE TX into the Mississippi valley this evening.
 
If the dryline slows down and can move across the metroplex even an hour or two later than expected, the metroplex risk of severe storms will increase dramatically.
 
Warning/Watch chances:
severe t-storm/tornado watch:
DMA – 60%
Metro – 35%
 
severe t-storm warning:
DMA – 60%
Metro – 30%
 
tornado warning:
DMA – 40%
Metro – 15%
