Shifting Pattern Brings Warmth to the Stateline

An incoming cold front brings a brief chilly snap midweek before warmer pattern takes precedence.

After a chilly Wednesday with highs stuck in the 50's, cloudy skies, scattered showers, and northerly winds will make it an uncomfortable day. But the dreary weather doesn't stick around as the pattern begins to change. In the upper levels of the atmosphere, low pressure will slide and anchor into the east coast as high pressure builds in the center of the United States; then a secondary low develops to the west near the Rockies. This pattern is called an Omega Block and resembles the Greek letter Omega. It's a blocking pattern that 'stops up' the movement of weather patterns as the atmosphere gets somewhat bogged down.

This brings cooler and wet weather to the east coast with the area of low pressure close by, as well as upward vertical motion in the atmosphere providing lift needed for rain. But this will bring reprieve to the rain soaked and water logged plains, with sunshine and warmer temperatures through the plains and into the Midwest. Expect temperatures to warm into the mid 60's on Thursday under a mostly sunny sky. The forecast gets better on Friday through, with highs warming into the upper 70's and low 80's.

Unfortunately the warmth and dry weather won't last as long as we'd like. Low pressure slides down the ridge, a cold front will follow on Saturday sinking south through the Stateline. This will bring more cloud cover, cooler temperatures, and scattered showers and possible storms through the afternoon.
