If conditions become unrepresentative...contact the National Weather Service. .DISCUSSION... Good morning, Afternoon showers and thunderstorms will be possible tomorrow evening after 3PM. Storms will be diurnally driven and isolated in nature, but given the day time heating and an approaching front it's likely that Roswell will at the very least be in the vicinity of a thunderstorm tomorrow evening. Highs in the upper 80s are anticipated under increasingly cloudy skies as the day goes on. Winds will be southwest at less than 10mph but could be gusty and erratic as a result of thunderstorm outflow boundaries. We'll be happy to run the spot again tomorrow morning and provide radar support during the time of the event. If you have any or questions or concerns, please feel free to give us a call. .THURSDAY... Sky/weather.........Partly sunny (50-60 percent).
