"APRIL showers bring MAY flowers."
Knoxville averages 4.01" of rain for the whole month of April. So far, McGhee Tyson Airport has only received 0.18" of rain during the first 11 days of April.
For East Tennessee...my forecast has NOT changed.
*** I am expecting 1 to 3" + of RAIN to fall on Easter afternoon and night, with locally HIGHER amounts, and where flash flooding could be an issue. ***
Here's my view of the most recent RAINFALL models for Easter. For purposes here, the "circles" below, in most cases, refer to 3, 4, 5 or more inches of rain. Hope this helps.
MODEL 1 usually underplays these types of weather situations.
MODEL 2 is by far and away the most aggressive, suggesting 3 to 6"+ of rain. I think it's too exaggerated. I'm calling MODEL 2 the "crazy rain train."
MODEL 3 tends to be more reasonable, and in this instance, is a good blend of MODEL 1 and 2.
MODEL 4, just like MODEL 3, is a more reasonable solution. The absolute worst of this storm should be to our South and West. Having said that, winds will kick into high gear here later Sunday night, and of course for the Smokies.
But what about Tornadoes ???
From the Storm Prediction Center
."..TN Valley into the OH Valley -- Sunday night...
Substantial uncertainty remains regarding the potential for destabilization from northern portions of the TN Valley into the OH Valley, due to the potential for widespread convection to the south of this area. However, rapidly strengthening wind fields in advance of the deepening cyclone will support the potential for damaging wind and perhaps a tornado risk by Sunday evening should even modest destabilization occur, as strong convection attempts to move in from the southwest in tandem with the deepening cyclone."
