A WINTER WEATHER ADVISORY is in effect for mountains above 5,500′ until noon Friday. Summer officially begins at 9:54am on Friday. Rain, wind, thunderstorms and that mountain snow will continue through the first day of the new season. Snow totals on the highest peaks could reach 12″. To say the least, Friday will not feel or look like the first day of summer. A FLOOD WATCH is in effect for areas near Fort Peck Lake as 2-4″ of rain is expected on saturated soil. The worst weather for the first day of summer will be up in northeast Montana where the wind will be strong and the rain will be heavy. The rest of the state won’t be much better as showers, thunderstorms and mountain snow will continue. Highs will be in the 50s in the lower elevations, 30s and 40s in the mountains. Saturday will not be much better with more showers, thunderstorms, wind, mountain snow showers and cool temperatures will prevail again. Highs will “warm” into the 60s for most of the lower elevations, 30s and 40s in the mountains. Sunday will be the nicer weekend day with mostly sunny skies and only isolated thunderstorms. Highs will be in the 60s and low 70s. The first week of summer will have cooler than normal temperatures with highs in the 70s. Isolated thunderstorms early in the week will become more widespread by Wednesday as another storm moves in. I do not expect real summer weather until the beginning of July, as cooler than average temperatures and showers, thunderstorms and high mountain snow will fly again into the final weekend of June.
Have a great day.
