We barely broke 60° yesterday which held steady during the daylight hours with a trace of rain after 7 am. After all the sunny days we had this past summer it sure has turned dreary which is a reminder of things to come in the Great Lakes region. For the records, below are the 72-hour rainfall totals for the 6th through the 9th.
Today will once again be cloudy however we have hopes of the sun returning tomorrow.
-- Drizzle early this morning, isolated showers possible today -- Drizzle and fog will continue early this morning, but it looks like we should stay above Dense Fog Advisory criteria based on high resolution model guidance. Some wind increasing in the lowest couple thousand feet out of the north should keep the fog from going widespread 1/4 mile or less. The lowest visibilities should be seen along I-94 through 5am or 6am this morning around 1 mile or so. Cannot rule out a stray shower this morning, but high resolution models are not bullish on precipitation. High pressure is nosing in from the north and the surface boundary is well off to the south so forcing for showers will be limited. We have isolated shower wording in for this morning (20 pct). -- Patchy frost potential along U.S. 10 tonight -- Model guidance suggests that the traditionally colder spots up in across Central Lower Michigan (like Leota in Clare County) will dip into the upper 30s tonight. Most locations will likely bottom out around 40 however. The MOS guidance at Houghton Lake which I like to use as a guide for our northern row is suggesting 36-38 degrees for a low. There is a bit of wind, around 10 knots, just off the deck so not expecting lows to really bottom out tonight. Bottom line, we may see some patchy frost along U.S. 10. Not frost headlines look to be needed. -- Showers and a few storms possible Saturday into Sunday -- An upper low seen in water vapor imagery tonight over the Four Corners region of the desert southwest will move our direction over the next 48 hours and transition into an open wave as its absorbed into the westerlies. This will be the main weather maker of the next 7 days with chances for precipitation from Saturday afternoon through Sunday morning. The best chances for precip will come Saturday night. The threat for thunderstorms looks to be small, but cannot be ruled out. I-96 to the south probably stands the best chances at some isolated thunderstorms but LI`s that barely go negative and CAPE values less that 500 j/kg are not very exciting. 60-80 pct pops are our highest Saturday evening/night. -- Mainly dry early next week -- High pressure builds in behind this wave with northwest zonal flow aloft. The period of Sunday afternoon through at least Tuesday looks pretty quiet. A front will be in the vicinity on Wednesday and we may have some showers then, but for now the forecast is dry. Temperatures through the entire period will be close to normals.
