Afternoon Severe Update

April 30th, 2014 at 1:44 pm by 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.

    As of 2:48pm no storms or rain yet but we do have gust of wind I would say about 25 mph at times.

    I forgot to mention I’m in the downtown Suffolk area

    With high dew points and temperatures across the entire region, the warm front well to the north, and CAPE values high as well, what is the final ingredient that sets up the solid line of showers and storms out by I-95 and not here in Hampton Roads? There are no nearby cold fronts to focus energy in one area compared to another, and yet all the storms seem to “train” over the same corridor (I-95) and not here, where conditions seem ripe for storms. What is it that causes storms to form there, but not here?

      Hi Ray. It’s possible that some of the storms to our south robbed the area of some of the energy. Also I think a lot of the blowoff from the western storms helped to stabilize things. Jeremy
