Weather Summary

After a soaking rain yesterday that produced 3 to 6 inches of rain the Baltimore and Washington areas, today's weather was a welcome change with plenty of warm sunshine and temperatures in the lower 80s. Humidity was lower today, but a reinforcing push of cool air will move through the area on Thursday as a weak cold front moves across the area during the afternoon. Behind the front, high pressure will build over the area. Temperatures will drop into the upper 50s at many locations (except lower 60s in downtown areas) by Friday morning with highs on Friday only in the upper 70s (lower 80s in downtown areas.) High pressure will ensure the continuation of sunny and seasonably warm weather over the upcoming weekend.
