Hot conditions expected for the first official weekend of Summer...

It was another hot and sunny day across southern Kentucky as a ridge of high pressure continues to shift from the northeast towards the Atlantic.  High temperatures topped out in the mid-upper 80’s across the area under partly sunny skies.  Diurnal convection this afternoon helped spark some isolated showers/storms across southern Kentucky as a weak inverted trough developed over the Bluegrass Region.  Lingering shower and storm activity is expected to continue into the late afternoon hours but should quickly dissipate this evening with the loss of heating. Generally, another mild night is expected as temperatures fall into the 60’s for most locations under partly cloudy skies.  Patchy fog could develop late tonight/early tomorrow morning especially along areas that received rainfall this afternoon.  The first day of summer will feel very summer-like across southern Kentucky as highs top out in the mid-upper 80's once again under mostly sunny skies. A slight chance for an isolated shower/storm will exist into the afternoon hours. 

NOAA/WPC Short-range Forecast Valid for Friday 12Z.

Over the next few days our region will be sandwiched between the Bermuda high just to our east and a stationary low pressure area east of the Central Rockies. A southerly flow will begin to provide increasingly warm, moist air into the Ohio Valley Region over the next several days allowing temperatures to gradually warm into the upper 80’s to around 90 degrees for the first official weekend of summer.  Much like today, the chance for an isolated shower or storm will exist as day time heating could spark some isolated convection across the area.  However, pop-up chances will remain low, as most areas should remain dry through the weekend. 

A look ahead...

Friday Night: Partly cloudy. Low 66º. South wind around 5 mph. 

Saturday: Mostly Sunny. Hot. High: 90º.  South winds around 5-7 mph. 

Saturday Night: Partly cloudy. Mild. Low: 68º. 

Sunday: Mostly Sunny. Isolated shower/storm. High: 89º. Chance of Precipitation: 20%. 

Sunday Night: Partly Cloudy. Mild. Low: 71º.
