Less Stormy Days Ahead for the Northeast, Texas in Slight Risk Area for Today

It looks like the severe/stormy weather that has been so persistent in the area of the Northeastern states over the last week or so has come to an end. This area is no longer in a risk category as the shortwave trough that is over the Northeastern States loses amplitude, and ejects northward into the New England states. As this trough loses it's amplitude heights are rising causing higher pressure to build into the area.

Along with high pressure, as most of us know, comes nicer weather, due to subsidence (sinking motion in the atmosphere). This sinking motion isn't friendly for developing storms because for those we need rising, vertical motion. Areas of high pressure lack that, therefore that's why we generally see very nice weather in these high pressure areas. Meaning that the Northeastern states should see some nicer weather after all those severe storms and tornado warned cells moved through the area all last week. The next day for potential storms in this area seems to be Sunday.

Here are a few radar images of some of the storms I have been seeing my area over the last week.







 Here are a few pictures of a shelf cloud from one of those storms. This cloud was actually associated with the last radar image. I was in meteorological bliss when snapping these photos. :)

Shelf cloud as it moved toward us.

Let's move on to where the interesting weather might be positioned for today. Taking a peek at the SPC day 1 outlooks, it seems that central Texas is in the risk area for today. Despite being in the slight risk area, it looks like the severity of the storms won't be incredibly strong. Central Texas should see widely scattered to scattered thunderstorms in clusters, that will be possible through the evening hours. Strong wind gusts and large hail are the main threats with these storms, as the tornado risk is to conditional and depends on storm scales processes, making it difficult to predict.

Short and sweet, but to right to the point folks. There isn't much more to report on. It looks like it's going to be a pretty quiet day, with the exception of the slight risk area in Texas and maybe a few other pop up storms in the green areas on the outlook map above.
