We have some drizzle this morning passing through Otsego with a temp of 49°. Most of the rain today will fall mainly south of Grand Rapids with the greater amounts in SE Michigan. Rainfall amounts of a tenth to a quarter-inch will fall in Grand Rapids and a quarter to a half in Kalamazoo. Of course, as usual, these are guesses and this past month the guesses seem to have erred on the high side. This should all clear out by tonight and temps will drop into the mid to upper 30s.
I am still waiting for enough rain to push the fertilizer on my lawn down far enough to kill the roots on the weeds – we have a nice crop of dandelions in the yard that shouldn’t be there. I generally don’t have many because I usually get the fertilizer down in early to mid-April and we generally have sufficient rain to work it down into the soil.
This is another reason to take short-range forecasts with a grain of salt. It is hard to forecast system precipitation more than a day out.
-- Light showers today -- Regional radar shows that we are just missing out on beneficial rain. A large band of showers and storms extends from the southern Plains northeast across Indiana, just nosing into far southern Lower. This is associated with low pressure moving over the northern Ohio Valley. Short range models suggest that some light rain will develop a little farther north and perhaps clip the southern CWA south of I-96. There are hints of that now in the latest composite radar profile. -- Frost Friday night, then warmer -- Colder air will flow into the CWA behind the departing low today. A look at h8 temps shows we`ll be cold advecting by mid morning today; temperatures will only top out around 60 today. Friday will be colder as h8 temps fall to -2c resulting in sfc temps in the lower to mid 50s. Frost is likely Friday night as the temperature falls to around freezing. Temperatures will rebound significantly over the weekend with upper 60s/lower 70s Saturday and mid 70s expected Sunday. -- Showers Monday -- Monday looks like the best chance for rain. Low pressure will move along a warm front across Lower Michigan beginning Sunday night and continuing through Monday. We may see some thunder Sunday night but instability wanes quite a bit by Monday and so just showers are expected.
