Maryland Weather: High Heat Will Be Present During Preakness

BALTIMORE (WJZ) — After a beautiful, dry, and sunny morning, clouds moved toward Baltimore as a warm front developed south of Maryland. 
An area of low pressure is bringing clouds and showers to areas in the Ohio Valley, and that rain is moving in this direction.
Look for showers to spread into the region, and at this point anywhere from one quarter to over half an inch of rain can be expected by the time it stops. 
All models are showing the bulk of rain over as early as 5 a.m.
