- Rain Today
Wave of low pressure moving along a stationary front will bring
rain and a few elevated thunderstorms today with QPF of a half to
three quarters of an inch across the Grand River basin which
could cause rises on the tributaries and mainstem rivers in the
Grand, Muskegon and Kalamazoo basins.The rain moves off to the
southeast this afternoon as sfc high pressure builds in.
- Excessive rainfall potential next week
Sunday through Thursday holds the potential for more flooding
rains as Plains lows track into the Great Lakes. This is similar
to the synoptic pattern last week that brought flooding and could
also result in severe weather depending on details that cannot be
resolved yet. Latest model guidance is suggesting this large
scale synoptic pattern persists even beyond day 7.
