CASPER, Wyo. — The persistent pattern of daytime heating leading to afternoon showers and storms continues for central Wyoming today.
However, meteorologists with the National Weather Service in Riverton say the pattern will soon break down as the flow of moisture from the Gulf of Mexico is cut off, but that will take another day or so.
For today, Casper is looking at a high of around 69 degrees with a 30% chance of scattered showers this morning and early afternoon. Where showers don’t occur, skies will be mostly sunny. Tonight should see a partly cloudy sky with a low near 53.
Wednesday will be breezy with a west-southwest wind of 13–23 mph. The forecast high is 74 degrees with clear skies in the morning. There is a 30% chance for afternoon rain that will remain through the overnight period. The forecast low is 51 degrees.
Casper’s greatest chance for rain this week comes Thursday, which will see chances rise from 20% to 60% during the day. Showers could become thunderstorms in the afternoon as the high reaches 72 degrees. There’s a 50% chance for thunderstorms overnight with a low near 48.
Friday also looks to be rather wet with a 30% chance for showers in the morning developing into a 50% chance for thunderstorms. The high will be limited to around 68 degrees.
Drier air is expected Friday evening, leading into a breezy but sunny Saturday.
