Heavy thunderstorms have erupted in central and eastern Montana. The western half of the state will have thunderstorms tonight, but it will not be hard. Parts of Far Eastern Montana are under a TORNADO CLOCK for the potential of tornadic supercell thunderstorms. Showers and thunderstorms will last tonight and pretty much all Friday. The last working day in June is cool, duschig, mostly cloudy and airy. There will be some thunderstorms capable of producing small hail, but the atmospheric energy required for heavy storms will have moved away from Big Sky Country. Highlights on Friday will be in the 60s, but 40s and 50s in the mountains. Heights over 8000 could even see wet snowflakes! This weekend will not be the best, but it will not be the worst. Saturday is partly cloudy with some showers and thunderstorms mainly over the Hi-Line and near the mountains. Heights get warm in the 60s and 70s. Sunday will be similar with a mix of sun, a few clouds, scattered showers and thunderstorms. The highs will rise to around 80 in the 70s. Next week will be a nice start to July. The highlights will be Independence Day in the 70s and 80s, but a few isolated thunderstorms will pervade each afternoon. For the 4th, strong thunderstorms in the northern part of the state are possible. Computer models have consistently produced thunderstorms scattered around July 4, so stay tuned as we get closer to vacation.
