As I have discussed several times prior to this, a persistent weather pattern has been fueling the heavy rain in our region and the split jet stream carries the upper level cold air down into Mexico and up through Texas mid section and when it hits the moisture laden Gulf air flowing in  where we are...well T-storms, hail, severe weather and heavy rain just can not help itself when it shows up.  
Another way of saying the same thing....In short, a southward dip in the jet stream has been locked in place over the western states, allowing it to launch disturbances into the Plains. It is those disturbances that provide the necessary lift in the atmosphere to trigger thunderstorm development as they intercept a warm, moist air mass in place near the surface of the earth.

Ok, I could just say......Unfortunately, it appears this weather pattern will stay in place through much of the rest of thisweek and into the weekend, allowing the bouts of rain and thunderstorms to continue to do what they do....give us lotsof rain, hail, damaging winds, dangerous lightning, flooding.....and everything else that goes with the pattern....If the forecast below is correct...we may only see...less than an inch of total rain through the weekend...anyone want to bet on that?
 

My automated station rain bowl was blown of level and the rocker arm did not reflect the actual rain we caught Monday...Thank goodness I have an old fashion glass gauge...It said 3 inches...ok, so it was just 2.97 as best I can guess...but at this point in the rainy season who's counting the hundredths!!
