Quick Dry…Then Storms Return

tempNOAARainTotals           Yesterdays storms missed most of Acadiana but there was some flooding mainly west near Lake Charles.   Rain fell at a rate of more than 2inches per hour.   This was a case of…”So close but yet so far”.  But not far enough.  The rain only saturated the ground further and any excessive rain will be problem  We have used much of the forgivness with soil saturation.  Meaning there is only so much the ground can hold, once saturated any rain will all become runoff.  Possibly you tested this in school using a dry sponge.   Soak the sponge in water, premeasured amount, and the sponge expand and hold’s the water within.  Then additional water added to the sponge is not help and runs out.  Same theory withthe earths soil.  Topsoil will only hold so much before it loses that ability.  Some soils have a greater capacity to hold water, soil with larger amounts of peat or organic materials hold more than soils contain clay    or sand.  tempWeatherServiceRainThe next storm system forecasted to be here by Thursday leaves us with little or no time to dry and not have additional Flood problems for Acadiana.   You can see how strong the storms were yesterday and what impact they had on the area. 

         The past storm systems have been progressive, moving quickly in and out, we have just seen more of them coming closer together.   Thursday’s weather will be a little different in that it will lack a definitive focus point for storms to develop.  The forecast calls for scattered storms first then followed by a strong to severe “squall line”,  with the Front when moving overhead in Acadiana.    Not going to take very long before the moisture returns to Acadiana and my focus remains on when the precipatation begins and how much we can expect.   Point is the ground is wet and if we see storms developing over the same area or the system slows some we will see flooding.
