Cooler Conditions Start the New Week; More Severe Weather Possible
July 20th, 2020
CHEYENNE, Wyo. (Wyoming News Now) -
As the new week gets started, the cooler conditions will be welcomed by many as there are no locations expected to eclipse the 90 degree mark. Overall the new week will be cooler, although a few locations will still see their fair share of 90+ degree days. Sunday evening saw its fair share of severe weather, with a tornado warned storm affecting Converse, Niobrara, and Northern Goshen counties. More severe weather will be possible on Monday afternoon, the main cause of which will be abundant surface heating and a dry line that has set up parallel to the Laramie Mountain Range. Higher dew points in far east Wyoming and the Panhandle of Nebraska will allow for higher humidity and a better environment for storm development. The surface heating will allow for instability and thus the formation of scattered storms in the afternoon/early evening. A few of these could be strong given the amount of energy in the atmosphere over the same region. The same region (albeit a bit further east) will likely see another opportunity for severe storm development Tuesday afternoon.
Overall through this week scattered storms will be possible each afternoon/evening with the chance that a couple could be strong to severe, however temperatures overall will be cooler when compared to last week. Also, the fire weather threat, while still a bit elevated due to hot and dry conditions for most of the state, will not be as substantial as late last week either due to an overall absence of stronger winds this week. Wind speeds could pick up late this week as a mid level trough moves through the area, bringing the fire risk up once again and also ramping up late week storm chances.
