Thursday

I've been combing over some of the most recent data, and from the looks of things, most of the lifting mechanism will be North of the Mississippi Delta. It is very difficult to pinpoint things from this range, but it looks as though the Delta may dodge the bullet. Don't plan on working your fields Friday though. Rain chances begin Wednesday night. Thunderstorms will fire during the day Thursday, but the atmosphere will be primed by Thursday evening for the Delta.  This event should be a decent rainmaker, with the Gulf pumping ample moisture into our region. The Storm Prediction Center has addressed concerns of hail with this system as it begins to hammer states in the midwest. I'm just not seeing that for our area.

No need to panic about your wheat getting pounded by hail. I do, however, suggest running some water furrows to make sure things drain well. I'm sure you've all done that by this point though. The moisture profile of this system has the capability for short-lived heavy rainfall in Thunderstorms.

Something to keep an eye on:

The image above is a forecast output for 850 mb Valid Midnight Friday. The red coloring indicates very high windspeeds (The Nocturnal Low Level Jet). High winds above the surface like this can be mixed down during thunderstorms, called a MicroBurst. This usually happens when a dry slot exists in the midlevels. Precipitation falls through the dry air, evaporates, cooling the dry slot rapidly, which subsequently sinks to the surface bringing its momentum with it. I don't see this being a problem since the moisture profile is so saturated, but it is worth noting.

I have read many other opinions of this storm, and some seem to think it is getting slightly hyped. Though that may be the case, and I tend to agree, everyone should stay aware of what is going on. To tie things up, main threat seems to be heavy rain, maybe very small hail in a couple thunderstorms. Nothing that warrants getting all of the equipment under the shed.
