LATEST UPDATE . Aviation . Hydro
SYNOPSIS. Issued at 155 PM EST Fri Dec 13 2019
* Some fog possible tonight
* Drizzle and freezing drizzle possible on Saturday
* Wintry mix may lead to slick spots on roads Saturday afternoon through Sunday morning
* Light snow possible early next week
DISCUSSION. (This evening through next Friday) Issued at 155 PM EST Fri Dec 13 2019
The main challenges over the forecast period deals with the potential for impacts.
Tonight there could some fog around the area. Temperatures will be near freezing. Thus a risk for a few icy spots exists. One limiting factor will be the cloud cover from the wave of low pressure lifting up the Appalachians. That shield of clouds will exist over much of the CWA for at least part of the night.
On Saturday and more so into Saturday night . light precipitation will be around. Temperatures during the day are forecasted to rise above freezing . thus little or no impact is projected during the day. As we go through the late afternoon hours into the the evening . the temperatures are likely to fall below freezing. Mid level height falls occur as a trough digs down. Lake moisture could feed into this system as it tracks through the Great Lakes Region. Initially the DGZ looks unsaturated later Saturday afternoon into the the first half of the night. Then it is forecasted to become barely saturated. All this points to a risk for a variety of light wintry precipitation types. Given the potential for below freezing temperatures we could see some impacts.
For Monday into Tuesday . guidance continues to track an area of low pressure up the Ohio Valley. Southern parts of the CWA from Kalamazoo to near Jackson are shown to be on the northwest fringes of the snow shield. Most model solutions keep the axis of heavier snow across Indiana and Ohio. We will feature relatively high POPs for southern parts of the CWA with light accumulations. We will need to monitor the system closely as a northward shift in the track could put more snow into our region. Following the passage of this storm system . a temporary surge of arctic air moves in. This will increase the lake effect snow which could lead to some travel impacts for the area along and west of a Big Rapids to Battle Creek line.
AVIATION. (For the 00Z TAFS through 00Z Saturday evening) Issued at 707 PM EST Fri Dec 13 2019
Expect VFR conditions to continue this evening then areas of MVFR and IFR may develop late tonight as low stratus moves in. The low clouds will persist through much of Saturday and some icing is possible in the cloud layer along with flurries or drizzle at times in the afternoon.
MARINE. Issued at 155 PM EST Fri Dec 13 2019
The pressure gradient will remain relatively weak through tonight which will act to keep the wave heights low. Then Saturday and more so Saturday night a northwest wind will develop and strengthen. We may need marine headlines to account for the wind and wave action. The potential for hazardous condition may exist into Sunday.
Another storm system early next week will be followed by the arrival of another arctic airmass. Hazardous weather conditions will likely persist/redevelop.
HYDRO. Issued at 711 PM EST Fri Dec 13 2019
River levels across most of West Michigan remain significantly higher than normal for this time of year, but are slowly trending down. The Maple River at Maple Rapids is still hovering around bankfull, but is following the trend of the other rivers with a slow drop.
Of note, a small freezeup ice jam on the Muskegon River between Big Rapids and Rogers Dam continues to cause minor flooding to several streets and a few homes in the area. Limited reports suggest water levels have been mostly steady today. Water levels around ice jams are wildly unpredictable, so some fluctuations both up and down can be expected over the next few days, but the overall trend should be slowly downward as warmer temperatures are limiting the growth of new ice that can come down the river and reinforce the ice jam.
