It's all about timing.
A dry line that was expected to help produce thunderstorms Friday in North Texas blew through Tarrant County around noon before anything significant could develop.
Only .09 inches of rain was recorded at DFW Airport, said Steve Fano, meteorologist with the National Weather Service in Fort Worth. Nearly .33 of an inch, however, was recorded at Alliance Airport.
"Tarrant County is pretty much done for this event," Fano said at 12:30 p.m. "It looks like the dry line is half way through Dallas County."

North Texas Friday morning was chock full of gulf coast moisture that could have been converted into thunderstorms, but a key ingredient -- unstable air aloft -- was missing from the formula, Fano said.
Dry lines usually don't come through until mid to late afternoon, which gives the atmosphere a chance to become unstable by daytime heating, Fano explained.
"(But) this dry line is moving through much earlier than a typical weather event," Fano said.
Fierce thunderstorms, meanwhile, were raking central Oklahoma and Kansas -- all part of the same system, said Mark Fox, another weather service meteorologist.
Kansas City TV stations reported 85 mph winds, numerous power outages and lots of wind damage.
But, while Tarrant County was spared of severe weather, East Texas was expected see the exact opposite as the dry line continued to move.
Strong but isolated thundershowers were spotted on radar moving across East Texas Friday afternoon, but the most powerful storms stretched deep into the nation's mid section and as far north as Minnesota.
