Patchy early morning fog is expected. In some areas, the fog could be locally dense with limited visibility. By mid-morning, fog should have burned off, and we can expect mostly sunny skies for the rest of the day. Highs will be in the upper 60s to around 70 today with light and variable winds anticipated. Another system will slowly cross the Upper Midwest into the Great Lakes by Friday night into Saturday. This looks to be a slow-moving system, though not much in the way of rain is expected at this time. A few rumbles of thunder are possible Saturday, and perhaps again Sunday afternoon as the front slowly moves through. Looking forward the CPC is guessing warmer than normal temperatures and drier conditions for the state.

Temperatures are chilly early this morning over the northern cwa. Leota is currently at 35 degrees. Most other readings are in the 40s. The Frost Advisory will remain in effect until 8 am. High pressure will be overhead today and begin drifting east tonight and Friday. Sunny skies are expected today and Friday with clear skies tonight. Highs in the mid to upper 60s are expected today and a few degrees warmer Friday. Lows tonight will fall into the 40s again under good radiational conditions. Look for lows in the upper 30s to lower 40s near US-10 and mid 40s elsewhere. Similar to today, some patchy fog is possible in low lying areas. -- Limited chances for precipitation in the long term -- The only real chance for precipitation during the long term period is during the Saturday through Sunday time frame. Southwest flow aloft will be in place to begin the period Friday night continuing into Saturday. An upper trough in the Northern Plains during this time will begin to push into Lower Michigan on Saturday. The first chances for a few rain showers will occur on Saturday across Central Lower Michigan. A small chance for a thunderstorm or two exists on Saturday as MUCAPE values try to approach 500 J/KG or so. Certainly not a lot of instability, but maybe just enough for a few rumbles. Our pops on Saturday are small across Central Lower Michigan, 20-30 percent. The best chances for showers and a few thunderstorms will come Saturday night into Sunday when the surface cold front associated with the upper wave is moving through. We have 30-50 percent pops in the forecast during this time frame. Instability fades a bit Saturday night, but returns on Sunday. Sunday will likely be the best chance for a few storms during the long term period as MUCAPE rises to around 1,000 J/KG. Dry weather is then forecast for the remainder of the long term from Sunday night all the way through next Thursday. Upper ridging gradually builds into the Great Lakes region for the middle of next week. -- Temperatures warming into the middle of next week -- Temperatures will be near normal on Saturday in a southwest flow at the surface. Highs will likely top out in many areas in the lower 70s. A cold front moving through on Sunday will bring clouds and precipitation that keep temperatures down a bit and below normal in the 60s. A warming trend begins from there with highs pushing into the upper 70s or near 80 for next Wednesday and Thursday. Both the 6- 10 day and 8-14 day temperature forecasts from CPC are showing above normal readings for our area. Much above normal heights are seen with either ridging or deep southwest flow in place aloft towards the end of next week.
