A storm crawling eastward will be the culprit behind another cool, dreary day over the mid-Atlantic today. The storm will deliver periods of rain, which will extend back to Michigan and Ohio. Motorists should prepare for slow travel. This is especially true where pockets of heavier rain pour down. Areas of fog will also obscure visibility. Flight delays could ensue in New York City, Philadelphia, Pittsburgh and Baltimore.

The rain and blanket of clouds will keep temperatures significantly below typical mid-April highs. Temperatures will be held to around the 50-degree mark.

Many places over New England and upstate New York will be warmer than the mid-Atlantic states. The comfortable weather will result from more sunshine with high pressure overhead.
