CHEYENNE, Wyo. — Cool and breezy conditions are expected in southeast Wyoming today as the upper high responsible for sunny days and warmer temps has flattened, allowing for winds from the west-northwest and more atmospheric moisture.

The National Weather Service in Cheyenne has forecast a high of 74 today under mostly sunny skies, with a 30% chance for showers creeping in at noon. That is likely to persist through about 9 p.m. Afternoon thunderstorms also are possible. Between 9 and midnight, rain chances fall to 20%, according to the forecast. Expect an overnight low of 48.

Wednesday will see a similar setup with a high of 76 under sunny skies. Winds from the south-southwest will provide that slight boost to the high. At around noon, there’s a 30% chance for rain the rest of the day, again falling to 20% between 9 p.m. and midnight. The overnight low will be near 47.

Thursday may well be a dry day with no rain chances. With mostly sunny skies, the mercury should reach 73. Overnight, skies will remain clear and the low will be near 47.

This week’s greatest rain chances come with the weekend. Friday, with a high of 69, will see a 40% chance for afternoon thunderstorms. Rain chances stick around in the forecast through Saturday. Drier air is expected on Sunday, and that will help return the high to the low 70s, if the forecast holds up.
