The northern Indiana office of the National Weather Service expects isolated thunderstorm development ahead of an approaching cold front, according to an email message the office sent to SKYWARN storm spotters and others this morning. “We expect that the severe threat will be ISOLATED and SHORT LIVED,” the email reads.
The message also provides the following timing and impact information:
- Through 3 p.m. EDT: Isolated showers and thunderstorms with gusts greater than 30 mph and lightning.
- 3 p.m. to 6 p.m. EDT: More organized lines of thunderstorms with isolated severe thunderstorm potential.
- 6 p.m. to 9 p.m. EDT: Threat of thunderstorms shifts south and east across the region with best organization and threat southeast of a line from Monticello, Indiana to Hillsdale, Michigan.
Numerous fairs/festivals and football games will be going on during this time frame. All venues should be making plans for thunderstorm development, monitor NWS Web pages and have NOAA Weather Radio programmed and operational.
