CASPER, Wyo. — It’s been a wet June, but you likely don’t need the National Weather Service to tell you that. It was plainly visible Thursday as parts of Casper saw temporary flooding at overwhelmed stormwater drains such as those on Collins and Poplar streets.

By the numbers, June has seen more than normal rainfall for the whole month and it’s not even halfway over. Data from the National Weather Service in Riverton shows Casper has received 1.41 inches of rain this month so far. June’s normal is 1.34 inches.

There’s little relief in sight from afternoon storms in the coming week, and this weekend is likely to be wet throughout.

Today should see a high near 76 degrees under mostly sunny skies. There’s a 20% chance for isolated thunderstorms in Natrona County this afternoon. Winds will come from the west at 6–10 mph. Tonight’s forecast includes a continued 20% chance of isolated thunderstorms as the low falls to around 54 degrees.

Saturday will start off with a 20% chance of storms, rising to 50% as the high approaches 69 degrees, according to the forecast. Up to a quarter of an inch of rain is expected, aside from higher amounts during thunderstorms, the forecast says. There’s a 40% chance for scattered thunderstorms overnight as skies remain mostly cloudy and the low falls to around 53.

Sunday will see slightly higher chances, with a 30% chance of showers rising to 60% in the afternoon. Skies will be partly sunny as the high approaches 70 degrees. There’s a 20% chance of showers and thunderstorms continuing overnight, according to the forecast.

The wet weather pattern will continue Monday and Tuesday, with dry morning forecasts and afternoon thunderstorms.
