Though it is not unheard of I hadn’t excepted these headlines quite this soon which generally has been in mid-October the past few years. Looking at the area matrixes for the state we could see the upper 30s south of I96 and at or near freezing north of I96. Some of the lower colder spots could drop into the upper 20s. These cold temps may be around for the next three nights. Daytime highs will be in the low to mid-60s through the weekend.
-- Cool through the weekend; nighttime frost threat -- Cold Canadian sfc high building in from the northwest brings chilly fall-like conditions into the region through the weekend with a risk of frost at night. Friday night will be the coldest night when the center of the sfc high will be overhead. Clear to partly cloudy skies and dry conditions will prevail the next several days and we`ve probably seen the last of the smoke aloft issue for a while per HRRR experimental guidance. Visible satellite imagery from yesterday confirms mostly smoke free skies under the approaching sfc high as the smoke guidance has been suggesting. Frost threat begins tonight, mainly across the nrn zones where sfc winds have the best chance of calming out. Some concern exists however regarding extent/coverage of strato-cumulus pouring swwd off Lake Huron and the HREF low cloud guidance does hint at that potential. Will issue a Frost Advisory for the nrn two rows of the GRR CWFA where confidence is highest, although it`s possible some patchy frost will develop south of that too if the winds drop off enough and skies are clear. Frost threat increases for Friday night and more of the area will be impacted, so a Frost Advisory may be needed for the entire area. Also a risk of freezing temps may develop across Osceola and Clare Counties. There will still be a frost threat on Saturday night as the sfc ridge holds, but we could have some mid and high level cloudiness coming in by that time. -- Temps rebound next week, still dry -- Guidance continues to indicate a warm up next week as upper trough lifts out and the sfc high pulls away. Still no signs of any substantial rainfall though as a dry air mass still prevails.
