The Storm Prediction Center (SPC) has issued a Slight Risk for a big stripe of the High Plains today.
There was no tornado threat originally, but now the SPC has bumped it up to a 5% Tornado threat.
The surface map shows a moderate south and southeasterly breeze, temperatures in the upper 70s F, and a sharpening dryline across the eastern part of Colorado.
I highlighted the dryline.
Looking at the SPC Mesoscale Map, there is a good bubble of Convective Available Potential Energy (CAPE) near Burlington, CO.
The biggest problem so far this morning is the cloud cover. Once again, we have a cirrus shield that is limiting some of our diurnal heating.
Here in Fort Morgan, it has been sunny, cloudy, and partly cloudy since I woke up, as different band of upper-level clouds have floated overhead. However, there is some clearing to our southeast.
I highlighted a feature of interest. On the satellite loop, it is moving east. Perhaps this boundary will help us?
The Supercell Parameter (SCP) hits a maximum along the I-76 corridor, but then again near Burlington, CO, later in the afternoon.
Gut feeling- we are going to have a line with a few embedded supercells. It’s going to be a mess to dodge. Our best bet may be a mesoscale accident ahead of the line, if one forms.
For now, we are headed southeast towards Siebert, CO, and I bet we trend east to Burlington before the day has finished.
Thank you for reading my post.
