Temperatures soared into the mid to upper 50s throughout southern Idaho on Tuesday, more typical for late March. A modest northwest breeze kept temperatures a touch cooler today, but hit-or-miss showers and thunderstorms still developed during the afternoon. There may be a quick heavy downpour with thunder this evening, but the area will dry out overnight.
Lingering moisture could lead to fog in valleys tonight into Thursday morning. However, we have spectacular late winter weather ahead. A building high pressure ridge will bring sunshine and warming temperatures each day, with temperatures approaching 60° by Sunday.
A dramatic shift is expected early next week. Temperatures will drop by 10-20°, with rain and snow showers in the valleys and heavy snow in the mountains. While it will be a shock to the system, the cold air will only stick around for a few days.
