Short Weekend Weather Update

Sorry for the lack of posts recently. I'm going full throttle through final exam season and trying to get all those end-of-semester assignments done in time. Unfortunately, it means my internet stuff (which, as everyone knows, is much more important than my college GPA) goes by the wayside for a week or two.

I'll be back posting in earnest starting Thursday. I'll have posts in between then, though.

It looks like the weekend will be active for severe weather across the central part of the United States. On Saturday, the severe weather threat will exist in the northern Plains as all modes of severe (tornadoes, damaging winds, and very large hail). The tornado and large hail threat will occur in the afternoon when the predominate storm type is supercellular in nature, and will evolve to more of a damaging wind threat once the supercells congeal into a mesoscale convective system later in the evening into Saturday night.
Severe weather probabilities on Saturday, issued by the SPC on Friday.
The severe weather threat will move southeast on Sunday as mainly a damaging wind and large hail threat.

Here's the quantitative precipitation forecast from the HPC, showing the amount of rain expected to fall between Friday and Sunday. The heaviest rain will be in the middle of the country, and almost all precip over the lower 48 seen on this map will occur as a result of convection. Fun fact: Almost all of the spring/summer precipitation that falls in the central United States occurs as a result of thunderstorms.
Temperatures will be very warm (ranging from the upper 80s in the south and slowly decreasing as one moves north), but will start to cool off from west to east as a cold front makes its way across the country late in the weekend into early next week.
