1 PM Sunday June 5 – Within a few hours the main line of storms will erupt ahead of a cold front. Warm air and the fast winds aloft will combine to produce storms that have the potential to become severe. It is important to note the NOT ALL storms will reach severe limits, so until they form and can be tracked, we all need to be cautious. Lightning and heavy rain can occur in any storm. Severe Thunderstorms mean wind speed reach 58 mph and or hail over 1 inch diameter is present. A tornado can mean rotation within the clouds spotted by Doppler Radar or a funnel cloud/tornado has been spotted visually. See the updated rain/storm timeline below. First, two things to pay attention to this afternoon:
Watch (Severe Thunderstorm or Tornado):
- When issued, a ‘watch’ covers a large area for many hours. This means there is the potential, not a promise of severe weather developing.
Warning (Severe Thunderstorm or Tornado):
- When issued, a ‘warning’ means a storm with these conditions is active and being tracked. This will usually cover a county our two with specific towns identified with less than an hour tracking.

Note, this HRRR model was over zealous with early afternoon developing showers that didn’t fully evolve as of writing this post. The main issue still will be the main line between 4 and 8 PM. Also notice that the line of showers redevelops across southern Maryland and the beaches past midnight.
