... An active weather pattern with rain and snow chances will continue as several disturbances cross the Great Lakes region. Very cold air will arrive Wednesday night and Thursday. A modest recovery in temperature is expected on Friday.
NEAR TERM /THROUGH TONIGHT/... Stratiform rain and snow driven by warm advection aloft will continue along and nwd from the warm-frontal zone across the region. Cold air aloft has maintained solid coverage of snow DUJ-BVI-MNN, while a cold rain has prevailed swd from this zone, with warm air (55F+ in MGW) noted outside of the rain swath.
Precipitation will continue for much of today as sfc low pressure shifts ewd across central WV in association with a low-amplitude shortwave trough. In the wake of the trough, colder air will return on nwly flow, heralding a transition to light rain/snow showers.
SHORT TERM /TUESDAY THROUGH THURSDAY NIGHT/... Lake-enhanced rain/snow showers will increase in coverage on Tue as another shortwave trough swings thru the Great Lakes region. QPF is limited, and the inversion height will remain below the dendritic growth zone, which will in turn limit snow accumulation despite the arrival of colder air.
The wrn-CONUS ridge that has maintained cooler air in the ern CONUS for the last few weeks, will amplify and shift ewd slightly, promoting an amplified ern-CONUS trough. A shortwave trough and associated sfc low pressure will advance ewd across srn Canada on Wed.
In the wake of this Canadian system, cold air will funnel into the region. Trajectories will favor lake enhancement especially in the I-80 corridor, but snow showers may advance farther swd than the usual snow belt.
An arctic chill will arrive Wed night as sky clears and wind subsides, with the lowest temperature seen yet this season forecasted for Thu morning. Despite strong insolation, the cold advection will offset diurnal heating, with maxima in the 20s expected in much of the region. These maxima will flirt with record-low maxima for Thu.
LONG TERM /FRIDAY THROUGH MONDAY/... A dry forecast continues thru Fri as ridging aloft takes hold on the region. The upper ridging also will support a quick return to more-seasonable temperature in the 40s on Fri, especially in the swrn half of the forecast area.
Precipitation chances (perhaps initially wintry late Fri night) return for the weekend as a trough advances out of the central CONUS.
