Wednesday Morning Update 

This last day of the month will be memorable. Today’s weather system has already brought in the rain a little earlier than expected, and it will expand across the region for the morning commute. See the live radar and forecast simulation to compare below.

However, the main story today will be about strong winds that could gust to 50 mph. the strongest winds are likely with the final line of storms passing metro areas between 2 PM and 4 PM.

Advisory Map

The Wind Advisories as of this morning are confined to the mountains (for now) with Small Craft Advisories on the Bay.  I would still consider securing your outside decorations and pay attention for any wind restrictions.

Headlines

• Morning: Rain steady 7 AM to 11 AM, Breezy
• Mid Day: Showers 
• Afternoon: Winds Gust to 50 mph (3 PM to 6 PM)

Peak Wind Gusts

Most areas will have gusts approaching the 45 to 50 mph range.

Reminder: This can knock down tree branches, holiday decorations, take trash cans down the street, and possibly lead to some restriction on bridges.

If you are flying or meeting someone arriving, there may be delays, and definitely turbulence to talk about.

Morning Temperatures

Notice the 20s and 30s in the Mid West… That is the air mass moving in behind this weather system.

Locally we will have a mild morning with southerly winds pushing mid 40s to near 50ºF.

Morning Surface Weather

A strong cold front is moving through eastern Ohio and will cross our region this afternoon. A Mesolow/Wave is trying to develop in northern Georgia out of the severe complex from yesterday.  This will enhance the rain for southern areas in addition to the instability above.

If you are flying there maybe delays, definitely turbulence!

Forecast Snapshot (7 AM)

The HRRR Model is updated the most frequently, and yet the rain again arrived earlier than shown here. Compare to the live radar below.
