Afternoon Severe UpdateApril 30th, 2014 at 1:44 pm by Jeremy Wheeler under Weather
I wrote a large blog this morning with a lot of details about today’s weather. Other than the storms firing up a little early, it has a lot of pertinent information about the forecast. Here is that blog: Jeremy’s AM blog.
One update is that there is now a tornado watch for most of the viewing area until 7pm tonight.
As predicted, storms are firing up and feeding off of the increasing instability in the atmosphere. The CAPE (amount of instability) has risen to about 2,000 – 2,500. 500 -1,000 is about the minimum for storms. Over 2,000 is pretty impressive. We had some sunshine earlier and so we have been heating up. I think the models and some forecasters underestimated the sunshine. Temperatures are in the upper 70s to near 80 already. There is some rotation in the atmosphere. So tornadoes will be a possible threat today. Again, the chance for severe weather is farther north than it has been over the last few days due to the deep moisture getting farther north. Heavy rain will definitely be a threat as well. Here is what Super Doppler 10 looked like at 1:30pm this afternoon.
Storms will increase and move east through the afternoon. Keep an eye on the sky. We will be tracking the storms the entire time. We will likely be cutting into programming. Be safe out there.
