4th of July Forecast: Southeast Showers and Storms

CHEYENNE, Wyo. (Wyoming News Now) – Cheyenne had two bouts of thunderstorms this afternoon with moderate to heavy rainfall the second time around. North of Cheyenne, the eastern half of the state was engulfed with numerous line and area thunderstorms as they tracked northeast toward South Dakota and Nebraska strengthening along the way. Wyoming did not have a severe thunderstorm threat today as that fell upon the surrounding states of Montana and the Dakotas again. Showers and storms will progress east Sunday evening across Wyoming and dissipate into the cooler night and morning temperatures.

Monday isn’t all clear weather-wise for the holiday. The forecast has brought general thunderstorms west slightly to include southeast Wyoming for the afternoon and early evening hours. This can put a damper on outdoor activities and early evening fireworks though the storms will be less frequent and less intense than what we saw Sunday. As a result, the southeast Wyoming region will remain cloudy until around midnight before it pushes east toward Nebraska. Tuesday is forecasted for early afternoon general storms with the exception east of Casper near the Lusk and Newcastle region where stronger storms briefly can drop small hail and high winds associated with the storm cells. A second wave of storms will originate in the early evening in Chugwater as it heads toward Scottsbluff.

Showers and storms are the repeating weather pattern for the foreseeable future with little change in the mesoscale air masses in the southeast and northwest parts of the country. This recurring pattern will impact the eastern half of Wyoming while the western half remains more sunny and dry. Temperatures are fairly consistent this week in the mid 80s to low 90s across Wyoming with hotter temperatures in the 90s in the Nebraska panhandle. Lows range from the low 60s to mid 50s throughout the week.
