Synopsis:
A strong Southerly flow will continue tonight ahead of sharp cold front and developing storm on the front. Readings will remain well into the 50s for a majority of the night with periods of rain. There will be dry times with areas of fog, but when the rain falls it could be heavy at times. Local flooding is possible.
The significant cold front will move through within a couple hours of sunrise. Rain is likely through early Saturday morning. The temperature gradient from the immediate coast to 150 miles North and West is extreme-from the 50s to the 20s. If the low is far enough East the cold air gets a chance to spill in before the precipitation ends over the Northwestern suburbs a freezing rain or a mix may occur. This has to monitored very closely. Whatever the case, the precipitation will end Saturday morning with temperatures falling into the 20s and 30s during the afternoon with returning sunshine.
Colder times will be with us for the rest of the weekend and into next week. A weak Alberta Clipper will race through the area on Tuesday with scattered snow showers. A more significant storm may develop off the coast on Wednesday. Where this storm forms and tracks is anybody’s guess, but it does have a low potential at this time to give the area accumulating snow.
Stay tuned.
