Above is a chance of any (measurable) rainfall map for between 10am and 10pm today generated by the percentages of all the members of the US Navy ensemble and past 6 runs of GFS that are forecasting precip.
You can see the general NW-SE oriented band of higher probabilities running down across the interior towards the southeast.
Even though a number of the storms may be dry storms, I still find probability of precip a good proxy for flagging areas for potential showers/storms, and some lucky places may get some decent falls if they can get directly under a cell. Of course there may be some locations which hardly get anything even in the higher probability areas but that's the nature of showers/storms.
