-- Changed Discussion --
A deep low pressure system will shift northeast from the Mid South into the Eastern Great Lakes through the forecast period generating a relatively lengthy period of showers and even the possibility of an isolated thunderstorm. Flight weather will gradually deteriorate to mvfr category at the terminals through the day as visibility drops below five miles in light rain showers and fog. Improving weather will develop from south to north through the day today as slightly drier air builds into the area on west to southwesterly winds behind the cold frontal boundary attached to the surface low. A healthy breeze with some gusts above 20 knots shifting from a southeasterly to westerly direction will develop at the terminals with the greatest impact at tys and tri.
