St. John Valley weather for March 13-19, 2019

Strong low pressure in eastern Colorado/western Kansas will track into Iowa Thursday then cross the Great Lakes into Canada Thursday night. Clouds will increase Thursday afternoon and evening as a warm front approaches producing a chance for showers across the Valley Thursday night. Light rain is expected across the region Friday as a cold front approaches. Rain tapers to showers after midnight Friday night. Showers are expected to continue Saturday before tapering to snow showers as a second cold front moves through the SJV. High pressure in Canada and the northern Great Plains builds east with colder air changing precipitation to snow showers Sunday that taper off later in the day. Partly cloudy to mostly clear skies are expected through midweek as high pressure dominates the Valley’s weather.
