What would most likely happen if a continental polar air mass clashed with a continental tropical air mass?

• The clouds would disappear and the day would become clear and sunny
• Cumulus clouds would form, and a big thunderstorm would occur
• Stratus clouds would form, and they would make the day warmer
• Clouds would form, and they would bring light and steady rainfall

Which best describes the effect on weather in an area if low clouds cover the sky during the daytime?
