Winter Relapse?

After a very active weather week across the region, cool and unsettle weather will visit for the weekend. Temperatures steadily warmed through the week and peaked in the lower eighties (80's) on Thursday before a cool front moved through that night. Severe weather during the week spawned numerous tornadoes which claimed two lives in Oklahoma. This weekend will feature quieter weather across the Nation with the exception of the Great Lakes and Northeast Region where an upper level low pressure will become established leading to cool and wet weather conditions. The weather over the weekend will be more typical of Fall as an air mass from the polar regions arrives. The low lifts out during the week and an airflow out of the south and west will moderate temperatures across the East as a trough becomes established over the West by next weekend.

Currently a strong cool front is moving through Great Lakes and Northeast regions. Rain showers will mark the arrival of the cool front and high temperatures will be fifteen to twenty (15-20) degrees below normal today and Sunday. Instability and lake effect showers will be possible as the coldest air arrives. Overnight Saturday snow may mix in across the highest elevations and Sunday night scattered frost will be possible for many areas away from Lake Erie.  On Monday high temperatures will rebound to around sixty(60) degrees as the next storm system approaches the area.

On Tuesday the next cool front will approach the region. High temperatures will once again be around sixty(60) with showers accompanying the frontal passage. High pressure will once again influence the weather on Wednesday with dry conditions and high temperatures in the lower sixties (60's).  Severe weather will possible on Tuesday as a storm system affects the southern Plains. Additional severe weather will be possible with this system as it moves across the Nation.

On Thursday the overall weather pattern will begin to change as high pressure dominates the East and a trough of low pressure moves onshore across the Northwest.  Conditions will remain dry and high temperatures will continue to rise and locally may reach the upper sixties (60's).
