Good Tuesday morning!  I hope you have had a great start to the work week and a great holiday weekend.  We had a pretty good weekend.  My son of course got a few items for Easter and we did a few things over the weekend.  We tried painting eggs and hey he enjoyed it.  I thought it left a pretty good mess, but at least he had fun.


Temperatures warmed back up on Monday and will continue to warm today and Wednesday.  However, the winds will start to pick back up as well.  So lets turn to our next storm system that is right on track with the Heady Pattern.  Remember, we are right on a 49.5 day cycle this year.  The cycle will last a few more months before it takes a turn which will will get into here later.  So lets look at this next system.  Today looks great across the central plains.

Temperatures look great on Wednesday as well.

However, our next system pushes in fast on Wednesday.

Wednesday 500

You can see the swirl across NW KS, that is the center of the energy for the next wave on Wednesday.  This is coming out with perfect timing to give us a severe weather shot tomorrow afternoon.  However, when I look at the map above I see a positive tilt.  This means the system is leaning forward and not backward.  On the other hand we do have pretty good shear (wind changing with height) and moisture is already feeding back into the plain states.  One big key here is the surface winds will be out of the south or just a hair out of the SSE.  This usually points to a better shot for stronger supercells across the region.  Back to the other hand, we will be strong capped (lid on the atmosphere, keeping storms from firing up) which means we won’t have a widespread outbreak of storms.  So with that said, lets look at what the NAM model projects for Wednesday evening.

You can see the area of Low pressure across eastern Nebraska with a dry line stretching south into eastern KS.  The NAM model want thunderstorms to fire along the dry line during the evening hours.  So here is my take with everything mentioned above.  At this time, I think we will have SCATTERED strong to severe storms that will develop after 4 pm tomorrow from SE NB into NE KS and east central KS.  These will most likely become severe with severe thunderstorm warning with hail and gusty winds.  We also can’t rule out a few tornadoes.  This would affect areas from St. Joe, KC, Lawrence, Topeka, Emporia to Ft. Scott.  As we work farther south into SE KS and NE OK, I expect isolated supercells.  Isolated means one here and one there.  These could go severe with mainly a hail threat as these will be more of an elevated threat.  A little father south in central OK, again we will see isolated supercells, but these will have more of a tornado threat due to the low level jet being stronger and some great upper level divergence.  All of these storms will plow east and become a line during the evening and start to fall apart becoming just a hail threat.  Of course as things evolve over the next 36 hours I will keep you updated.
