It is not all that common to see these higher level risks issued 2 to 3 days in advance. That is why we need to watch this system very closely. However, it is still too early for specifics. A lot of small details that we won't know until tomorrow or Tuesday will ultimately decide how this event plays out. It looks as though one round of storms along a warm front will move through early Wednesday, setting the stage for severe storms ahead of a cold front Wednesday afternoon and evening. All modes of severe weather will be possible, including damaging winds, tornadoes, large hail, and flash flooding. We should be able to start nailing down some specifics tomorrow.
Now is the time to prepare for severe weather Wednesday. Since this is our first widespread severe weather threat of the Spring season, here's a checklist to remind you of how you can prepare.
