Outflow Boundary

Everything in the world is due 4/29. I left the office at midnight last night, and overslept this morning (didn’t get up until around 6!), so I won’t be doing a full prediction today.

There is still a Slight Risk in place across the Midwest and Dixie Alley based on the same system as yesterday’s storms, though the tornado probability is much lower.

I did want to address the severe threat from yesterday. The super tornado outbreak didn’t happen; storms went linear very quickly. This did end up as a hail event, with many reports of large hail and gusty winds, however. Here are the reports as shown by the Storm Prediction Center (SPC) graphic:

Also, I did capture this radar image as the system moved through Texas. What I want you to notice is the faint blue line ahead of the squall line; that is the outflow boundary from this system. This is where the precipitation-cooled air leaving the storm has made itself a little cold front, pushing under warmer air in front of the system. Sometimes, the outflow boundary can be the trigger for more storms, or perhaps where a storm can produce a tornado, and yet other times, it can deamplify a storm. This one just pushed along ahead of the squall line.

Thank you for reading my post.
