Record High Temperatures Monday

CHEYENNE, Wyo. (Wyoming News Now) - Sunday was hot across Wyoming as weather was mostly absent. Monday will be even hotter. The only weather question is when clouds will start to fill the skies as all locations enter the max heating hours of the day. As of now, south and southeast Wyoming, to include the Nebraska panhandle, are forecasted for additional cloud coverage and the start of isolated rain showers and thunderstorms by 2 to 3pm. By this measure, it can thwart rising temperatures to reach as high as they would otherwise. My forecast for the most records is in western Nebraska, because it is hotter at lower elevations and northern Wyoming as there will be less clouds and rain in addition to temperatures hotter than the Cheyenne region.

Monday will be very breezy as winds ahead of the cold front will increase along the eastern border early Monday morning exceeding 30 mph. By the late morning and early afternoon winds in northwest Wyoming will exceed 40mph as the cold front nears. Throughout the afternoon wind speeds will increase throughout the state to 30-35 mph for many locations. Monday evening and Tuesday morning will remain breezy with winds in the mid 20 mph range as cold front continues to slowly push through Wyoming. Tuesday afternoon will be breezy as well after the cold front has passed with the frontal boundary and tight pressure gradient nearby.

Tuesday will start a reprieve from record high temperatures as some cool air behind the cold front settles in over Wyoming. While it is not a deep cold air mass, it does break the ridging from the high pressure over Colorado. This change of weather will knock down high temperatures to tolerable above average for the remainder of the week by summer standards. Wyoming gets a weather break Tuesday after the cold front passes but by Wednesday we are back area thunderstorms as desert heat and moisture are likely to spill our way for the return of summer thunderstorms.
