We have a cool start for today with a temperature at 5 am of 38°. Yesterday we reached 62° for the high and 45° for the low. While today will be cool and dry, a slow-moving storm system will bring periods of showers Saturday into Tuesday. Thunderstorms, though not severe are expected Sunday into Sunday night.
The outlook for October is calling for a good chance of above-normal temperatures
--Patchy Frost early, Fair weather otherwise -- Winds remain constant at about 2 to 5 mph overnight, with some areas going calm. temperatures up north have dropped to 35. Dewpoints have remained around 38 to 40. If dew`s remain above 35 with just enough wind, this will preclude frost formation. However, it could allow for shallow ground fog this morning. Any fog will dissipate shortly after sunrise as the atmosphere mixes. --Period of showers and possibly storms this weekend-- The ridge of high pressure that has given us pleasant weather Thursday will shift eastward as a negatively tilted upper level low will move through the upper mid west and through the Great Lakes region this weekend. The negatively tilted trough will protrude through the lower levels. A weak warm front will move into the region Saturday. Current temps are still a tad low currently and will adjust upward. Showers will be possible daytime Saturday, especially north of the I 96 corridor. The cold front will swing through late Saturday. An upper level jet streak that will move over the Lower peninsula will be the driver of this frontal pattern and should allow enough forcing for a chance of thunderstorms Saturday night through Sunday afternoon. Any storm formation will be dependent on frontal forcing as model soundings show weak inversions, conditional stability and a lack of CAPE. Showers, however, are likely though PWATS are only around an inch. The total QPF through Sunday will be a half an inch or less. --Showers continue through Monday-- The large closed low that will be dominating weather through the weekend will shift to the east Monday. While we will be on the backside of this low, successive troughs and copious amounts of moisture will continue to stream into the region. The winds will have shifted to the north, dropping temperatures. Rainshowers will be possible as instability with this system will continue Monday into Tuesday.
