A Relatively Cool Week On Tap For Late April Over Southeast Lower Michigan

Look for temperatures to average 5 to 10 degrees below normal over Southeast Lower Michigan through much of the week. On average, late April should bring us high temperatures in the lower to mid 60s; while lows fall into the lower to mid 40s.

First up on our weather agenda: a strong low pressure system will rev-up over the East; then pivot somewhat north-northwest toward eastern Great Lakes region - in the vicinity of Lake Ontario - by Tuesday morning.

Southeast Lower Michigan will be on the western fringe of this large storm center as it draws down cold polar air into the Eastern Great Lakes. The air should be cold enough for snow over portions of Ontario; southward into western New York and Pennsylvania along with eastern Ohio early in the work week. In our neck of the woods, the main effects from the system will be a brisk and gusty north wind and cool temperatures; along with varying amounts of cloud cover There is the outside chance of some light showers Tuesday as the large storm skirts the region; pushing its way north into eastern Canada. Temperatures into mid week will generally see highs rise into the 50s with lows in the 30s. Wednesday looks to be our warmest day at this time with readings attempting the lower 60s.

While the briefly warmer weather will return to the region by mid week it will be short lived as another re-enforcement of cold air; dives quickly southeast from southern Canada and surges across the Great Lakes later Wednesday into Thursday. Cool, below normal temperatures will continue to prevail into the weekend.
