Warmer with Light Rain & Fog

Yesterday we had some sun and warmer temps.  The high was 45° and the low was 27°. The temperature will be climbing today with many locations topping out in the 45 to 50-degree range. Light rain and fog may develop during the afternoon and more so this evening. A cold front arrives Friday with more showers expected. The fog could still persist.  It is not taking long for the snow to melt because of its low moisture content.  With the warming of the snowpack and higher dewpoints, we could see some fog development around the area.

Forecast Discussion

- Warm and wet weather ahead

A quasi stationary high over the Atlantic has a ridge to extend
through Nova Scotia. This has allowed warmer air to be advected
into the the Great Lakes today and into tomorrow.
 An amplifying trough the will continue deepen through the central
plains will ride the ridge bringing a tightening gradient through
SW Michigan.

The upper level trough will be amplified through the mid and
lower levels. A strong upper level jet will drive and filter
through down resulting in a low level jet that will bring gusty
winds at times today and tonight. The warm air advection today
will be coupled with drizzle and fog though the moisture will be
fairly widespread but sparse overall. The fog formation will be
aided by higher dewpoints and warming from the snow pack.
 While the ridge will slowly shift eastward, a ribbon of moisture
will form along the boundary Friday into Saturday. The moisture
however will be mainly in eastern Michigan and through the Ohio
River valley.

 A relatively mild cold front will swing through Saturday and will
drop temperatures, yet they will remain above freezing. Colder
air aloft could bring a rain/snow mix along and north of the I 96
corridor.

The warm and wet pattern will continue into next week with more
warm air advection Tuesday. Mid range models have some
differential in the mid level heights, however all solutions bring
shower through Tuesday

- Cooler weather and snow possible next weekend

Then yet another shortwave in the wave train comes on shore of
the West Coast and creates another lee side surface low.
This will bring another round of rain showers. next weekend.
However, on the back side there is a decent chance for lake effect
with colder air that could bring snow back to the ground.
