Moderation Ahead Of The Arctic Blast

5:48 AM

Strong high pressure is now in control of the forecast area, which means the strong winds of the past two days are now at an end.  Clear skies can be expected today through tomorrow as high pressure slides through the forecast area.  Temperatures will rebound to near normal levels today and tomorrow as a strengthening southwesterly wind takes hold.

On Friday, the pattern changes towards the colder once again.  Clouds will increase through the day as a strong Arctic cold front plows through the Ohio Valley and moves towards the forecast area.  Ahead of the cold front, strong southwesterly winds will bring very warm conditions into the forecast area.  Temperatures will rise quickly into the 40’s and 50’s ahead of the front.  By the evening, the cold front will slowly move through the forecast area with rain, heavy at times.  There may even be some embedded thunderstorms.  The cold front is going to move slowly due to the orientation of the northern branch of the jet stream being parallel to the surface cold front.  Complicating matters will be a potential jet streak over the forecast area that may enhance wind gusts within the rainfall.  So looks like Friday nights rush hour is not going to be pretty.  

Temperatures will crash into the 20’s and 30’s behind the cold front on Friday night with rapidly clearly conditions behind the cold front passage due to the strong dry air advection.
