Friday rain, but we'll salvage weekend in metro Detroit

You'll need your umbrella most of next week

By Paul Gross - Meteorologist

DETROIT - Yesterday I discussed the possibility of a cut-off low pressure area bringing an extended period of cool, wet weather next week, and that projection unfortunately still looks on track.

But let's start with the short term forecast, and then get to next week's bad news -- after I also remind you to follow me on Twitter at @PaulGrossLocal4 so you can receive my periodic updates.

After a possible sprinkle or light shower this evening, the rest of the night should be dry, with lows in the low 40s. East-southeast wind at 8 to 13 mph.

Friday forecast:

Rain develops probably in the middle of the Friday morning rush hour, and continues into the early afternoon. Rain will then taper off from west to east, and should clear the Detroit metro area by 3-4pm (later for you folks in Ontario, of course). The sun will come out shortly after the rain ends so, if you had dreams of grilling your Friday dinner, I think you'll be able to.

Temperatures will struggle through the 40s during the morning, and then pop into the upper 50s to near 60 as long as the sun returns by 4pm. If the sun is as little as an hour or two later in coming out, we'll stay the low to mid 50s. Variable wind at 8 to 13 mph.

Mostly cloudy Friday night, with lows in the low 40s.

Weekend forecast:

Partly cloudy to start your Saturday, then becoming mostly sunny. Highs in the mid to upper 50s. Mostly clear Saturday night, with lows in the mid 30s.

Partly cloudy on Sunday, with highs in the mid 50s. Partly cloudy Sunday night, with lows in the mid 30s.

Partly to mostly cloudy and breezy on Monday, with showers possible by mid to late afternoon (best chance is south of Detroit). Highs in the low 50s. Shower chances continue Monday night, with lows in the low 40s.

Now get ready for this: breezy with periodic rain Tuesday through Thursday, with highs generally in the upper 40s to low 50s, and overnight lows in the low 40s. Some of my long-range computer models - most notably the GFS - keep rain chances in the forecast through Saturday, while the ECMWF model tries to be a little more progressive and moves the cut-off low east a little sooner.

The bottom line is that most of next week is going to be a rough one for outdoor activities, so be ready for this high school, middle school, and little league coaches.
