Wet start to weekend possible in Valley

Showers, thunderstorms in forecast late Friday night, Saturday

The St. Croix Valley could see its first significant rainfall since mid-August with showers and thunderstorms possible to start the weekend.

The National Weather Service put the chance of rain in the metro area at better than 50 percent Friday night through Saturday.

The chance of rain follows a high-pressure system that moved into the region early today, bringing breezy conditions and temperatures holding steady in the 40s much of the day.

NWS forecasters said high pressure would build over the region today, bringing clearing skies, diminishing winds and laws falling into the middle 20s tonight.

Friday will start sunny with light winds and a high near 52, forecasters said. But a vigorous low-pressure system will move northeast from the Central Plains late Friday, spreading showers and thunderstorms into central and southern Minnesota and western Wisconsin by Saturday.

There is a 70 percent chance of showers and thunderstorms in the Valley after 1 a.m. Saturday, with increasing clouds and lows near 43.

The chance of rain jumps to 80 percent Saturday with highs near 63 and southeast winds around 10 mph. There is a 70 percent chance of rain before 1 a.m. Sunday with lows falling to 47.
