Weather Summary

Today's weather was a pleasant contrast to yesterday's damp, cold, and wintery weather. The pressure gradient between an exiting area of low pressure and high pressure building over the Ohio Valley created strong winds today that gusted over 30 miles per hour at times. Despite the wind, the sky was mostly sunny with afternoon temperatures in the mid 60s. Winds will gradually diminish as we head into the evening hours and temperatures will fall back into the upper 30s with a clear sky, high pressure overhead, and light winds. After a cool start to the day on Tuesday, a southerly flow around the center of high pressure will enable thermometer readings to bounce back into the mid 60s. A cold front will approach the region on Wednesday. This will produce increasing cloudiness during the afternoon hours, but it will be mild with highs approaching 70. A wave of low pressure moving along the frontal boundary is expected to result in widespread rain showers on Thursday and Friday with highs in the 50s. At the moment, it appears that both Saturday and Sunday will be mostly sunny and pleasant with highs in the 50s to near 60. The average high for early April is in the lower 60s.
