After spring-like weather today, St. Lawrence County temperatures are expected to fall into a more-normal but still mild winter pattern starting Tuesday.

Temperatures rose a little higher today than had been forecast, but predictions are calling for it to be a little cooler than normal by the end of the week.

Today's sunshine will give way to clouds tonight and a 40 to 50 percent chance of some snow showers tonight and tomorrow morning, one to two inches at most, according to the National Weather Service.

The high temperature tomorrow under partly sunny skies will probably not rise much above tonight's low of about 23 degrees. Then the thermometer drops to the single digits Tuesday night before rising to near 30 on Wednesday with sunny skies.

Temps drop to below 20 Wednesday night and will rebound to the mid-30s Thursday with partial sun.

The chance of shower rises a bit on Thursday night with lows about 13, and continues Friday, with a high of about 16.

Friday, Saturday and Sunday night could see below zero temps, with cloudy daytime conditions and highs ranging from the mid-teens Saturday to near 30 on Monday.
