[NLRS] Winipeg to Minneapolis 10GHz !

Wed, 30 Jul 2003 09:37:07 -0500

Hi Guys.
Playing with the map just now seems to indicate that when storms are ~75 mi
WSW of Fargo to ~100 mi ESE of Fargo, you should have the best chances.
There's lots of summer thunderstorm season left, and 754 km would be the new
record.  (Besides, Mike, its a new one for the count on "States Above !")
