Actually, my issue with the cell phone weather widgets is Rogers County (they'll send an alert to Oolagah for a cell over Inola, or Chelsea for a cell in Catoosa) and the cell phone company.
In the cell phone company's case, it's how the towers "circles" of coverage cross county lines. I think this is what happened yesterday. The cell was going SW to NE across Sperry, headed for between Skiatook and Collinsville and then up towards far NW Rogers County. At the time, the warning box stopped at the Tulsa and Washington to Rogers county line (145th E Ave - as the cell was still out at or about 52nd W Ave. But the cell TOWER that my phone was affliated with is actually just west of 161st E Ave(and thus its coverage extends well into Tulsa County and in the warning polygon) but that tower only GAVE the warning because the box crosses the western half of it's coverage circle.
The cell didn't actually get within 15 miles of my house and fizzled so the warning was never extended into Rogers County proper.
I did get one later (text message from Rogers County EMA direct via their group push message) - for a storm coming out of NW Wagoner county that just clipped Inola. That one was just the county being behind the times and sending the push for their "whole world".
