National Weather Service Detroit/Pontiac MI
337 PM EDT Thu Apr 19 2018

.DISCUSSION...Tightened pressure gradient will begin to relax tonight
as high pressure builds in from the west, resulting in a reduction
in winds and gusts across the area. This high will persist through
the weekend and high temps will reach the 50s each day,
gradually moderating toward the low 60s by early next week.
Dry air filtering in will allow relative humidities to fall to the
30 to 40 percent range.
