LATEST UPDATE . Aviation

SYNOPSIS. Issued at 332 AM EST Thu Jan 23 2020

- Mostly light snow west and central today into this evening

- Next system brings mixed precipitation Friday that changes to mostly snow Friday night into Saturday

- Warmer than normal but not much sunshine early next week

- Complex storm middle to the end of the week

DISCUSSION. (Today through next Wednesday) Issued at 332 AM EST Thu Jan 23 2020

--Mostly light snow west and central today into this evening--

We expect light snow (possibly mix with rain in the afternoon) over most of central and western CWA today the lead shortwave tracks through the area ahead of the primary system on Friday. We are on for the most part under the upper level jet core associated with the upper wave moving through the area over the next few days. This puts us on the nose of the 1000/850 moisture transport vectors and brings our precipitable water values up from near 1/4" early this morning to around a 1/2" by evening. This will saturated the column of air over us and allow the snow currently falling over our western CWA (but not reaching the ground) to finally start reaching the ground by mid morning. Model sounding show the air cold enough for snow so the only way to get rain is to warm the surface temp into the mid 30s(which seems not to likely). With limited moisture transport, this will not be a big QPF event, likely on the oder of a tenth of an inch. Snowfall will thus be in the 1/2 inch to 1 inch range depending on how much can accumulate with marginal surface temperatures.

--Next system brings mixed precipitation Friday that changes to mostly snow Friday night into Saturday--

The more significant system for us will be Friday into Saturday morning. All of the models showing a 120 knot jet core diving into the back side of upper trough early this morning will lead to a very closed off upper low that tracks through northern Ohio Saturday morning. This puts us in the classic place for FGEN/cold conveyor belt/trowal precipitation event. Typically these sorts of events overperform. The ECMWF ensemble mean QPF for this event is around 1/2 inch. Most of this will fall during the afternoon into early morning hours of Saturday. It will be just warm enough Friday afternoon for rain in southern areas and mixed precipitation farther north. The strength of the lift will cause enough thickness cooling to turn the rain to snow over the area by mid evening. We are thinking 1 to 2 inches of snow but I could see this being more than that. We will have to see how this plays out. It will be a wet snow and with temperatures near freezing I do not see to many impacts. This all lifts out of the area by Saturday afternoon,

--Warmer than normal but not much sunshine early next week--

Thanks to shortwave ridging and the northern stream staying over the arctic, it will be warmer than normal most of this coming week.

--Complex storm middle to the end of the week--

Later in the week another strong Pacific storm moves on shore over the western CONUS and develops another deep trough over the central CONUS. This time though there may be more cold air around to work with so this could be notable system.

AVIATION. (For the 12Z TAFS through 12Z Friday morning) Issued at 629 AM EST Thu Jan 23 2020

This is one of those days were it will be largely IFR at MKG and largely VFR and JXN through the day into the evening. It just works out there is a feed of deep moisture that is more North/South and its not spreading east much. So the low clouds and snow will stay west of Lansing into the evening.

There will be two periods of precipitation in the next 24 hours. The first one is coming through now and that will for the most part by snow. The second system is more organized storm system and that comes through this area Friday. However the moisture in front of the system reaches this area tonight. It will move from south to north reaching the I-94 taf sites by midnight. This second system has warmer air with it so it should more so be snow. This will also bring widespread IFR with it.

MARINE. Issued at 332 AM EST Thu Jan 23 2020

We will let the small craft advisory expire as forecast, it is up still due to the 3 to 5 foot waves having not subsided to under 4 feet yet.

HYDROLOGY. Issued at 325 PM EST Wed Jan 22 2020

Other than a localized ice jam in the Kalamazoo River near Comstock, rivers are experiencing declining levels with little or no ice cover in place. No new ice growth is expected in the coming days given rising surface temperatures. Precipitation totals from Thursday through Sunday will likely not be significant enough to produce any substantial rises on rivers but may slow descents.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
